Answer:
The tree is 28 feet in height.
Step-by-step explanation:
This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.
74 / x = 102/39 Cross Multiply

The quotient of y and 6 is 29 find the value of y
Answer:
Addition → 23
Since 29 is a prime number and does not have least common factors beside itself and 1, there is only addition here, which would be 23 + 6.
Answer:
174
Step-by-step explanation:
If y/6 is 29, we need to do an inverse operation to find Y.
The inverse operation of division is multiplication.
29*6=174
Meaning, we've found y! Y=174
How to check?
174/29=6.

Answer:
3/20
Step-by-step explanation:
Given:
Probability that it is Monday and that a student is absent is 3/100
Probability that a randomly selected day of the school week is monday is 1/5
To Find:
What is the probability that a student is absent given that today is Monday.
Solve:
It may be different if it were on a Wednesday. Because we expect fewer absentees on Wednesday than on Monday/ Friday. In these cases the conditional probability, P(absent/weekday) would differ depending on the day of the week.
3/100 ÷ 1/5 = 3/20
The probability that a student is absent on a Monday is 3/20

suppose y=2x-16 and y=x+2. what is the value of x?
Step-by-step explanation:
Set two equations equal to each other
2x -16 = x+2
x = 18
Answer:
18
Step-by-step explanation:
Make the two equations to each other by subbing out the y
2x - 16 = x + 2
Move the like terms to one side
Subtract x from both sides
2x - 16 = x + 2
-x -x
x - 16 = 2
Add 16 to both sides
x - 16 = 2
+ 16 + 16
x = 18
X will have to be 18 for these equations to be true.
how many natural numbers less than 50 have exactly 4 positive factors?
Options:
a) 13
b) 15
c) 17
d) 11
Answer:
15
Step-by-step explanation:
We will use the Tao function for our use. If there are 4 factors of a number then Tao function has a value of 4.
According to the Tao function, (a1 + 1)(a2 + 1).....(an + 1) = 4. So, by comparison We have two cases.
Case 1: a1 + 1 = 4
So, in that case a1 = 3 and we see there are two cubes less than 50.
Case 2: a1 + 1 = 2, a2 + 1 = 2
So, a1 = 1 and a2 = 1. Thus, it's a pure multiple of linear primes. And we notice there are 13 such numbers.
Write an equation of the line passing through the points (4,6) and (-2, - 18).

Use slope formula and plug in your numbers: [tex]m = \frac{-18-6}{-2-4 }[/tex]Solve for slope [tex]m = 4[/tex]Use the point-slope formula to solve for the equation: [tex]y-6=4\left(x-4\right)[/tex]Solve and find equation: [tex]y=4x-10[/tex]Note: When given two points you only need to pick one for the point-slope formula! Best to choose the positive one so you don't have to deal with the negatives!

Explain why Justine is correct or incorrect.
the second claim of justine is that the only angle of rotation that shows rotational symmetry is 120 degree is correct.
A rotational symmetry implies that the shape remains the same when rotated
Justine's claim is correct
How to determine the true statementThe angle of rotational symmetry is calculated as:
[tex]\theta = \frac{360}n[/tex]
Where n represents the number of sides.
From the complete question, the shape is a regular hexagon.
This means that n = 6.
So, we have:
[tex]\theta = \frac{360}6[/tex]
Divide
[tex]n = 60[/tex]
Other angles of rotational symmetry are:
[tex]n = 60, 120, 180, 240.....[/tex]
120 degrees is part of the list of possible angles of rotational symmetry.
Hence, Justine's claim is correct

What is (3. 1 times 10 Superscript 5 Baseline) (2. 2 times 10 Superscript 7 Baseline) in scientific notation? 5. 5 times 10 Superscript 12 6. 82 times 10 Superscript 12 5. 5 times 10 Superscript 35 6. 82 times 10 Superscript 35.
The sum of the numbers expressed in scientific notations is given by: Option B: [tex]6.82 \times 10^{12}[/tex]
How does scientific notations work?The number is written in the form [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
Better readability due to compact representationIts value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.The given expression is:
[tex](3.1 \times 10^5) \times (2.2 \times 10^7)[/tex]
Evaluating the multiplication, we get:
[tex]3.1 \times 2.2 \times 10^5 \times 10^7 = 6.82 \times 10^{5 +7} = 6.82 \times 10^{12}[/tex]
It is because of exponent rule that [tex]a^b \times a^c = a^{b+c}[/tex], and because of commutative property of addition.

Justin wants to buy a new pair of jeans. If the jeans were originally $50.00, but are on sale with a 30% discount, how much will Justin have to pay for the jeans?
Answer:
$35.00
Step-by-step explanation:
Step 1: Multiply 30 by 50.
30 × 50 = 1500Step 2: Divide 1500 by 100.
1500 ÷ 100 = 15Step 3: Subtract 15 from 50.
50 - 15 = $35.00Answer:
35 dollars.
Step-by-step explanation:
The easiest way of calculating discount is, in this case to multiply the normal price is $50 by 30 then divide it by 100. So, the discount is equal to $15. To calculate the sales price, simply deduct the discount of $15 from the original price $50 then get $35 as the sales price.

Solve the system:

y=-2x-2
(__,__)?
Answer:
(-3, 4)
Step-by-step explanation:
First, substitute y=-2x-2. We have 3(-2x-2)=9-x ---> -6x-6=9-x Then isolate the x. -5x=15 Simplify, we have x=-3. Then we can input this x-value back into one of the equations. We have 3y=9--3 ---> 3y=12 ---> y=4. So the solution to this system is (-3, 4).
