It takes 8 feet to wrap the small box and 12 feet to wrap the large box
Step-by-step explanation:
The cheerleaders from Campo high school are doing a gift wrapping fundraiser at a clothing store
Yesterday, they wrapped 36 small clothing boxes and 25 large clothing boxes, using a total of 588 feet of wrapping paper
The day before, they wrap 27 small clothing boxes and 29 large clothing boxes, using a total of 564 feet of gift wrap
We need to find how much paper it takes to wrap each size of box
Assume that they need x feet to wrap a small box and y feet to wrap a large box
∵ The small box is wrapped by x feet
∵ The large box is wrapped by y feet
∵ They wrapped 36 small clothing boxes and 25 large clothing
boxes, using a total of 588 feet
∴ 36x + 25y = 588 ⇒ (1)
∵ They wrapped 27 small clothing boxes and 29 large clothing
boxes, using a total of 564 feet
∴ 27x + 29y = 564 ⇒(2)
Now we have a system of equation to solve it
Multiply equation (1) by -3 and equation (2) by 4 to eliminate x
∵ -108x - 75y = -1764 ⇒ (3)
∵ 108x + 116y = 2256 ⇒ (4)
- Add equations (3) and (4)
∴ 41y = 492
- Divide both sides by 41
∴ y = 12
- Substitute the value of y in equation (1) or (2)
∵ 27x + 29(12) = 564
∴ 27x + 348 = 564
- Subtract 348 from both sides
∴ 27x = 216
- Divide both sides by 27
∴ x = 8
It takes 8 feet to wrap the small box and 12 feet to wrap the large box

Answer:
417.5500
because 49 is lower than 50
can anyone do these ?
Answer:
1. (x-6)(x+1)
Verify = x² + x - 6x - 6 = x² - 5x - 6
2. (x+8)(x-5)
Verify = x² - 5x + 8x - 40 = x² +3x - 40
3. (x-10)(x+3)
Verify = x² + 3x - 10x - 30 = x² - 7x - 30
how to find the missing side of a triangle in trig for geometry
Step-by-step explanation:
cosine is cos(angle)= adjacent/hypotenuse
sine is sin(angle) = opposite/hypotenuse
Tangent is tan(angle)= opposite/adjacent
for all of those
if the equation is something like tan(69)= x/69
multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator
if it is something like tan(69)= 69/x
just swap x and tan(69)
it is much easier
it will then be 69/tan(69) and put that in the calculator

What is the reflection of the point (-5,2) in the line y=2?
Answer:
-2/5
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

- solve the system using elimination....
x - 3y = -11
-x + 2y = 7
We minus these equations : x - 3y - (-x + 2y) = -18
= x - 3y + x - 2y = -18
2x - 5y = -18
Now, we add these equations :
x - 3y = -11
-x + 2y = 7
-> x - 3y - x + 2y = -4
-y = -4
y = 4
Replace it in 2x - 5y = -18
2x - 20 = -18
2x = -18 + 20 = 2
x = 1
Recheck : 1 - 3 x 4 = -11
-1 + 8 = 7.
Two congruent squares and a parallelogram were used to form the figure shown.

What is the area of the figure in square meters?
25.8 m2
40.8 m2
34.8 m2
28.8 m2
Answer:
the answer is 40.8 m2
Step-by-step explanation:
The area of a figure is the amount of space the figure occupies
The surface area of the figure is 34.8 square meters
How to determine the area of the shape
From the question, we have:
The dimensions of the congruent squares are 3 m by 3 m
The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 * Area of square + Area of parallelogram
This gives
Evaluate the products
Evaluate the sum
Hence, the surface area of the figure is 34.8 square meters

so the answer is 40.8 m2
The area of a figure is the amount of space the figure occupies
Hence, The surface area of the figure is 34.8 square meters
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Now, From the question, we have:
The dimensions of the congruent squares are 3 m by 3 m
The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 × Area of square + Area of parallelogram
This gives;
Area = 2 × 3 × 3 + 2.8 × 6
Area = 18 + 16.8
Area = 34.8 m²
Hence, The surface area of the figure is. 34.8 square meters

explain how the unit circle definition of sin and cos is related to the equations sin(theta)=O/H and cos(theta)=A/H
The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex].
How cosine and sine are related in the unit circleThe unit circle is a particular case of the Pythagorean theorem, in which hypotenuse ([tex]r[/tex]) has a measure of a unit. That is:
[tex]x^{2}+y^{2} = r^{2}[/tex] (1)
Where:
[tex]x[/tex] - Horizontal leg[tex]y[/tex] - Vertical legIf we divide the entire expression by [tex]r^{2}[/tex], then we have the following identity:
[tex]\left(\frac{x}{r} \right)^{2}+\left(\frac{y}{r} \right)^{2} = 1[/tex]
And by trigonometric relations, we have the following formula:
[tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex] (2)
The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex]. [tex]\blacksquare[/tex]

1. A bottling company uses a machine to fill the bottles with olive oil. These bottles are
designed to contain 475 millilitres (ml). In fact, the contents vary according to a normal
distribution with a mean of 473 ml and standard deviation of 3 ml. A) What is the distribution, mean, and standard error of the sample mean of six randomly
selected bottles?
Using the Central Limit Theorem, it is found that the distribution of the sample mean of six randomly selected bottles is approximately normal, with mean 473 ml and standard error of 1.22 ml.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this problem, for the population, we have that:
[tex]\mu = 473, \sigma = 3[/tex]
Then, for the sample of n = 6:
[tex]s = \frac{3}{\sqrt{6}} = 1.22[/tex]

songs, n, are NOT pop?
How can you draw a picture and write an equation to
represent the problem?
Answer:
7/12
Step-by-step explanation:
Draw a rectangle with 12 squares. 5 of them will be pop and 7 will not.
The equation will be 12/12 = 5/12 + n. You will subtract 5/12 from each side and get 7/12 = n.

a family buys 5 airline tickets online. The family buys travel insurance that costs $17 per ticket. The total cost is $1,495. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Answer:
$282
Step-by-step explanation:
The price per ticket can be found by dividing the total cost by the number of tickets, then subtracting the value of any per-ticket add-ons.
5(x +17) = 1495 . . . . . total cost of 5 tickets with 17 per ticket ins charge
x +17 = 299 . . . . . . divide by 5
x = 282 . . . . . . . price of 1 ticket
The price of one ticket is $282.
