Answer:
27 trees needs to be in the orchard.
Step-by-step explanation:
amber needs to harvest at least 2293 of plums to cover the cost of running the orchard.
but also wants to donate 280 plums.
each tree produces an average of 83 plums
find: how many plums of trees needed to be in the orchard?
number of trees required = total harvest / number of plums produced per tree
therefore,
number of trees required = 2293 / 83 ≅ 27 trees needs to be in the orchard.
so Amber can donate 280 plums to charity.

Answer:
$125$65, $65, $65 -- they are all the sameStep-by-step explanation:
The quantity of food required for the two cats for one day is ...
(3/4 can) + (1/2 can) = (3/4 +2/4) can = 5/4 can
Then the cost per day for cat food is ...
$5/(3 cans) × (5/4 can/day) = $25/12 /day
We note that the cost for some number of days will be the product of this factor and the number of days, rounded up to the next higher $5.
1. The cost for 60 days is ...
(60 days)($25/12 /day) = $25 × 60/12 = $125
A 60-day supply of cat food costs $125.
__
2. A 29-day supply costs ...
(29 day) × $25/12 /day = $60 5/12, rounds up to $65 for 29 days
A 30-day supply costs ...
(30 day) × ($25/12 /day) = $62.50, rounds up to $65 for 30 days
A 31-day supply costs ...
(31 days) × ($25/12 /day) = $64 7/12, rounds up to $65 for 31 days.
These costs are all the same.

In general, what can you conclude about a pair of angles that are both congruent and supplementary?
Answer:
Both angles are right angles.
Step-by-step explanation:
Supplementary angles sum to 180°. Since we know that both angles are congruent, let's call them x and x. We can write the following equation:
x + x = 180
2x = 180
x = 90°
Therefore, we can conclude that both angles are right angles.
Answer:
Angles that are both congruent and supplementary each have a measurement that is equal to 90°.
Step-by-step explanation:
Eric took $7000 of his income last year and invested it, part at 7% and the rest at 9%. He earned $570 from investments. How much did he invest at each rate?
Answer:
He invested 3,000 at 7% and 4,000 at 9%.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=7,000 (1)
0.07x+0.09y=570 (2)
You can solve for x in (1)
x=7,000-y (3)
Now, you can replace (3) in (1) and solve for "y":
0.07(7,000-y)+0.09y=570
490-0.07y+0.09y=570
0.02y=80
y=80/0.02
y=4,000
Finally, you can replace the value of "y" in (3):
x=7,000-4,000
x=3,000
According to this, the answer is that he invested 3,000 at 7% and 4,000 at 9%.
Which row of table reveals the x-intercept
The row of table reveals the x-intercept could be second ( -4, 0).
What is x-intercept of a function?The x-intercept of a function of variable x ( y = f(x) ) form is an intersection fo the x-axis and the curve of the function.
The x-intercept for a function y = f(x) is a solution to the equation f(x) = 0 because at that value of x, the function f(x) lies on x-axis where y is 0.
Values of x-intercept for a function f(x) are also called roots or solution of f(x) = 0 equation.

d) How many three-digit numbers greater than 330 can be formed from the digits 0, 1, 2, 3, 4, 5, and 6?(
The question is incomplete. Here is the complete question.
(a) How many three-digit numbers can be formed from the digits 0,1,2,3,4,5 and 6, if each digit can be used only once?
(b) How many of these are odd numbers?
(c) How many are greater than 330?
Answer: (a) 180
(b) 75
(c) 105
Step-by-step explanation:
(a) In the group, there are 7 digits. A three-digit number can not start with zero, otherwise, it will be a 2-digit number. So:
For the hundreds position, there are 6 choices.
For the tens position, since the digit can be used only once, there are 6 choices.
For the unit position, there are 5 choices.
The total three-digit number formed is: 6*6*5 = 180
(b) To form an odd number, the unit position must be an odd digit, then:
unit position has 3 choices;
hundreds position has 5 choices;
tens position has 5 remaining choices.
The total three-digit odd number is: 3*5*5 = 75
(c) The number formed must be greater than 330, so:
If the number start with a 3, to be greater, there are 3 other choices (4, 5 and 6), so Tens position has 3 choices and Unit position has 5 choices.
Total number is: 3*5 = 15
Another possibility is the number starts with a digit bigger than 3 and so, there are 3 choices.
Tens position has 6 choices;
Unit position has 5 choices;
Total possibilities are: 3*6*5 = 90
The total number of ways a three-digit number is greater than 330 is:
90 + 15 = 105
. In double integration , we keep one variable say x fixed and _______ a. Reliable the order variable y b. Varying the order variable y
Answer:
A double integral can be written as:
[tex]\int\limits {f(x, y)} \, dx dy[/tex]
Now, to do this integral, we first can fix one of the variables, like in this case, we can fix x.
Now, with x fixed, this will be a function of only one variable, y, then we can do the integration over y.
Once the function is integrated over y, we can now do the integration over x.
Then the correct option will be:
" Varying the order variable y"
We keep x fixed, and integrate over the other variable.
if you are dealt 4 cards from a shuffled deck of 52 cards find the probability that all 4 are hearts
Answer:
Probability of getting 4 hearts = 11/833
Step-by-step explanation:
Find:
Probability of getting 4 hearts
Computation:
Probability of getting 1st heart = 13 / 52
Probability of getting 2nd heart = 12 / 51
Probability of getting 3rd heart = 11 / 50
Probability of getting 4th heart = 10 / 49
Probability of getting 4 hearts = [(13 / 52)(12 / 51)(11 / 50)(10 / 49)]
Probability of getting 4 hearts = 11/833
What is the top of the flag pole above ground in inches?
Answer:
13ft 10.2in
Step-by-step explanation:
First let's convert 3ft to in.
3 * 12 = 36 in
Now let's find the angle
We use tangent because we know the opposite and adjacent distances.
tan x = 36/13
tan x = 2.7692
On your calculator, input the value of your tangent. Then press "inv." This should give you the angle associated with that value. The angle associated with tan 2.7692 is 70.14 degrees.
Now that we know the angle we can find the height.
We use tangent again.
tan 70.14 = x / 5 We don't know the opposite but we know the adjacent length is 5ft.
2.77 * 5 = x
13.85 ft = x
To get it in ft and inches multiply .85 by 12
.85 * 12 = 10.2
13ft 10.2in

Using the online regression calculator :
The regression model obtained in the form:
ŷ = mx + c is ;
ŷ = 1.792X + 52.176
Where ŷ is the predicted or dependent variable
m = 1.792 is the gradient or slope of the regression line
x = the independent variable
c = 52.176 = intercept, where the line of best fit intersects the y axis.
Given the following x values, predict ŷ
(a) x= 11.5
ŷ = 1.792(11.5) + 52.176 = 72.784
(b) x= 8.0
ŷ = 1.792(8.0) + 52.176 = 72.784 = 66.512
(c) x = 15.5
ŷ = 1.792(15.5) + 52.176 = 79.952
(d) x = 10.0
ŷ = 1.792(10.0) + 52.176 = 70.096
The predicted values are meaningful as they show are very close to the actual values of height (y). This could be attributed to the high correlation Coefficient of 0.9299 which exists between both variables
The distance from home plate to the fence in dead center at the Oak Lawn Little League field is 280 feet. How far is it from the fence in dead center to third base? [Hint: The distance between the bases in Little League is 60 feet.]
Answer:
241.3 feet
Step-by-step explanation:
From the above question, we solve for this using the law of cosines
Law of cosines
a² = b² + c² -2bc Cos A
a = √b² + c² -2bc Cos A
a = The distance between the bases in Little League = 60 feet
b = ???
c = The distance from home plate to the fence in dead center at the Oak Lawn Little League field = 280 feet
A = It makes an angle of 45°
This is because the distance 60 feet and 280 feet are perpendicular to each other and they meet at a point that divides a right angle 90° into equal parts.
a = √280² + 60² - 2 × 280 × 60 × Cos 45
a = 241.33216 feet
Approximately = 241.3 feet
How far is it from the fence in dead center to third base? 241.3 feet

Step-by-step explanation:
Architectural Design The "rise to run" ratio of the
roof of a house determines the steepness of the roof.
The rise to run ratio of the roof in the figure is 3 to 4.
Determine the maximum height in the attic of the house
if the house is 32 feet wide.
Answer:
12 feet
Step-by-step explanation:
For an inclined roof, the rise is the vertical distance from the roof rafter to the vertical top plate while the run is the distance from the edge of the wall to half of the center of the ridge.
The slope is the ratio of the rise to run. Given a rise to run ratio of 3 to 4. The house is 32 feet wide.
The run of the roof = half of the width of the roof = 1/2 × 32 feet = 16 feet
Let the rise of the roof (height of the attic) be x, hence:
rise to run ratio = height of attic/ run of roof
3/4 = x/16
x = 3/4 × 16
x = 12 feet
The height of the attic is 12 feet

$1000 invested with compound interest at a rate of 15% per year for 9 years. Formula: M = P(1+ i)n Group of answer choices $3517.88 $424.36 $1519.38 $888.15 $1788.14
Answer:
Option A.
Step-by-step explanation:
Note: Let as consider, we have to find the total amount after 9 years.
It is given that,
Principal amount = $1000
Rate of compound (yearly) interest = 15% = 0.15
Time = 9 year
The formula for total amount is
[tex]M=P(1+i)^n[/tex]
where, P is principal, i is rate of interest and n is number of years.
Substituting P=1000, i=0.15 and n=9, we get
[tex]M=1000(1+0.15)^9[/tex]
[tex]M=1000(1.15)^9[/tex]
[tex]M=1000(3.5178763)[/tex]
[tex]M=3517.8763[/tex]
[tex]M\approx 3517.88[/tex]
So, the total amount after 9 years is $3517.88.
Therefore, the correct option is A.
graph the piecewise function
show how you got the function
(4). If we break down this piecewise function, we have 3 main expressions to deal with, 'h(x) = 5 if {x ≥ 4}' (represented by the green graph) 'h(x) = x if {0 ≤ x ≤ 4}' (represented by the blue graph) and 'h(x) = 1 / 2x + 2 if {x < 0}' (represented by the red graph).
Take a look at the attachment below for your graph of these 3 functions / expressions.
(5). For this part we want to determine the average rate of change of the function f(x) = 4x² - 5x - 8 over the interval [- 2,3]. Remember that to calculate average rate of change between the 2 points we use the following formula...
f(b) - f(a) / b - a,
f(3) = 4(3)² - 5(3) - 8 = 4(9) - 15 - 8 = 36 - 15 - 8 = 13,
f(- 2) = 4(- 2)² - 5(- 2) - 8 = 4(4) + 10 - 8 = 16 + 10 - 8 = 18
13 - 18 / 3 - (- 2) = - 5 / 5 = - 1
Therefore the average rate of change of the function f(x) = 4x² - 5x - 8 over the interval [- 2,3] will be - 1.
