Which of the following can be represented by the inequality below? 69h + 126 > 540 A. Yvonne is driving more than 540 miles on a trip. She has already driven 126 miles and drives 69 miles each hour. B. Yvonne is driving less than 540 miles on a trip. She has already driven 126 miles and drives 69 miles each hour. C. Yvonne is driving less than 126 miles on a trip. She has already driven 69 miles and drives 540 miles each hour. D. Yvonne is driving more than 540 miles on a trip. She has already driven 69 miles and drives 126 miles each hour.
Answer:
The answer is A.
Step-by-step explanation:
The inequality states that the amount that Yvonne drives is more than 540 miles. Since h represents the number of hours, we know that 69 probably means the number of miles Yvonne can drive per hour. Finally, 126 shows the amount of miles that Yvonne has already driven.

A football team consists of 20 offensive and 20 defensive players. The players are to be paired in groups of 2 for the purpose of determining roommates. If the pairing is done at random, (1) how many ways are there to divide the 40 players into unordered pairs of 2 each
Answer:
780 ways
Step-by-step explanation:
We have a football team consisting of 20 offensive and 20 defensive players.
The total number of the team would be:
20 + 20 = 40
Now, we must choose pairs, that is, 2, people, therefore it would be the combinations of 2 of 40 (40C2)
nCr = n! / (r! * (n-r)!)
replacing we have:
40C2 = 40! / (2! * (40-2)!) = 780
I mean there are a total of 780 ways

Answer:
w=80
Step-by-step explanation:
The Exterior Angle Theorem states: The exterior angle formed by an extended sign of the triangle is the sum of the two angles in the triangle that it is not directly next to.
In this case, the exterior angle is w+44.
The interior angles we can use are w and w-36.
We can set up an equation:
w+44=w+w-36
Combine like terms.
w+44=2w-36
Add 36 to both sides.
w+80=2w
Subtract w from both sides.
w=80

The graphs below have the same shape. What is the equation of the blue
graph?
Answer:
Option (A)
Step-by-step explanation:
Parent function (in red) graph is represented by,
f(x) = x²
If this function is translated by 'a' units to the right, rule to be followed,
f(x) → f(x - a)
If the parent function is shifted by 4 units to the right (blue graph), the new function will be,
g(x) = f(x - 4)
g(x) = (x - 4)²
Therefore, Option (A) will be the correct option.

Find the missing side length
a plane flies 90 kilometres on a bearing 030 and then flies 150 kilometres due east how far east of the of the starting point is the plane
Answer: 45√3 + 150 ≈ 227.94
Step-by-step explanation:
A bearing of 30° means we can create a 30-60-90 triangle. We are looking for the x-value = 45√3 ≈ 77.94
Add to that value, the additional 150 due east.
77.94 + 150 ≈ 227.94

Answer:
TUV=52
Step-by-step explanation:
2z+65+59+26z=180
28z+124=180
28z=56
z=2
26*2=52
Answer:
TV
Step-by-step explanation:
The sum of the angles of a triangle are 180
z+59 + z+65 + 26z = 180
Combine like terms
28z + 124 = 180
Subtract 124
28z = 180-125
28z =56
Divide by 28
28z/28 = 56/28
z=2
The smallest side is opposite the smallest angle
26*2 = 52
<u is the smallest angle so TV is the smallest side
In a local ice sculpture contest, one group sculpted a block into a rectangular based pyramid. The dimensions of the base were 3 m by 5 m, and the pyramid was 3.6 m high. Calculate the amount of ice needed for this sculpture.
Answer:
87.6m²
Step-by-step explanation:
From the above question, we are given the following information
The dimensions of the base were 3 m by 5 m:
Length = 3m
Width = 5m
The pyramid was 3.6 m high
Height = 3.6m
To calculate the amount of ice needed for this sculpture, we would have to find the Surface Area of the Rectangular Prism
This is calculated as:
Surface Area =2(wl+hl+hw)
= 2(3 × 5 + 3.6 × 3 + 3.6 × 5)
= 2(15 + 10.8 + 18)
= 2(43.8)
= 87.6m²
The amount of ice needed for this sculpture is 87.6m²

For the data set 7, 5, 10, 11, 12, the mean, x, is 9. What is the standard
deviation?
==================================================
Explanation:
The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the [tex](x-\overline{x})^2[/tex] terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so [tex]\sum(x-\overline{x})^2 = 34[/tex]
From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list
So,
[tex]s = \sqrt{\frac{1}{n-1}\sum(x-\overline{x})^2} \\\\s = \sqrt{\frac{1}{5-1}*34} \\\\s = \sqrt{\frac{1}{4}*34} \\\\s = \sqrt{0.25*34} \\\\s = \sqrt{8.5} \\\\s \approx 2.91547594742266 \\\\s \approx 2.9 \\\\[/tex]
This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.

WILL GIVE BRAINLIEST 5 STARS AND THANKS....An automated machine takes any cardboard rectangle and cuts off a square whose side length is equal to the shorter side length of the rectangle. Peter had a rectangle and, using only the machine, got out of it 2 large squares, 3 medium squares, and 5 small squares whose side length is 10 cm. What were the dimensions of Peter's rectangle?
Answer:
Dimensions:
x = 130 cm
y = 10 cm
Step-by-step explanation:
Let´s call "x" and "d" sides of the cardboard rectangle x > y
then we have to cut along x three pieces of y length to get three squares of sides "y".
We have two squares of side y, the third one we cut in half and get two rectangles with sides y and y/2, we cut to get 4 squares with sides y/2 then so far we have
2 large squares ( side y )
4 medium squares (side y/2) we just need three
We need to cut the available square side y/2 in 4 to get y/4 squares
Finally, we need y/4 length to get the fifth y/4 square
Then dimensions of the cardboard
x and y
We cut 3 times at "y" length and need additional 10 cm
Then the side y/4 is equal to 10 cm then y = 40 cm
and x = 3*y + y/4
x = 3*40 + 10 = 130 cm

Avery wants to buy a car and has a choice between two different banks. One bank is offering a simple interest rate of 3.2% and the other bank is offering a rate of 3% compounded annually. If Avery decides to deposit $7,000 for 5 years, which bank would be the better deal? 1. a simple interest rate of 3.2% 2. a compound interest rate of 3%
Answer: a simple interest rate of 3.2% will be the better deal.
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r/n) nt
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Nominal Interest Rate (decimal form, 3/100= 0.03)
n= number of compounding periods in each year (1)
Replacing with the values given
A = 7000 (1+0.03/1)^(1x5)
A = 7000( 1.03)^5 = $8,114.92
For simple interest:
I = p x r x t
Where:
I = interest
Replacing with the values given:
I = 7000 x (3.2/100) x 5 = $1,120
Adding the principal amount: 7000+1120 = $8,120
Since 8,120 (simple) >8,114.92(compound)
a simple interest rate of 3.2% will be the better deal.

,
Calculate,
(i) area of sector,
Answer:
The area of the sector is 21.39 cm^2
Step-by-step explanation:
Mathematically, to calculate the area of a sector, the formula to use is;
A = Theta/360 * pi * r^2
where Theta is the angle subtended at the center of the circle = 50 degrees
r is the radius of the circle = 7cm
pi = 22/7
Substituting these values into the area of sector equation, we have;
A = 50/360 * 22/7 * 7 * 7 = (5 * 22*7 )/36 = 21.39 cm^2
