The correct inequality that describes the problem is 4x ≥ 40. Thus, the correct answer is A.
The answer is A because Ms. Wells is ordering 4 large cheese pizzas, and she expects to spend at least $40 on the pizzas. The inequality 4x ≥ 40 represents the total cost of the pizzas, which is 4 times the cost of each pizza (4x) and should be greater than or equal to $40. This inequality tells us that the total cost of the pizzas is at least $40, which is what Ms. Wells expects.
Option B, 4x > 40x, is incorrect because it doesn't make sense mathematically. The right side of the inequality is 40x, which is not related to the problem, and it also doesn't make sense that each pizza will cost 40 dollars.
Option C, 4x ≤ 40, is incorrect because it represents the total cost of the pizzas as less than or equal to $40, which doesn't match with Ms. Wells' expectation that she expects to spend at least $40 on the pizzas.
This question should be provided with answer choices, which are:
A. 4x ≥ 40B. 4x > 40xC. 4x ≤ 40The correct answer is A.

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run

7 3/4 subtracted by 2 2/5
show your work
Answer:
5 7/20
Step-by-step explanation:
basically, you are going to want to turn these into improper fractions
7 3/4 = 28/4 + 3/4
= 31/4 (no further simplification)
2 2/5 = 10/5 + 2/5
= 12/5
now get common denominator to subtract
31/4 - 12/5
155/20 - 48/20 = 107/20
if you want this back into mixed fraction then convert
107/20 = 5 7/20

Sally has 30 feet of ribbon. She cuts strips each of length 2 2/5 feet from the ribbon. Sally says I can cut 13 of these strips from this ribbon.
Answer: See explanation
Step-by-step explanation:
For us to know the number of strips that Sally can cut from the ribbon, we have to divide 30 feet by 2 2/5 feet. This will be:
= 30 ÷ 2 2/5
= 30 ÷ 12/5
= 30 × 5/12
= 25/2
= 12 1/2 strips
Therefore, the maximum number of strips that Sally can cut is 12 and not 13.

16 is the geometric mean of 8 and what other number n
9514 1404 393
Answer:
32
Step-by-step explanation:
The geometric mean relation says ...
16 = √(8n)
256 = 8n . . . . . square both sides
32 = n . . . . . . . . divide by 8
The other number n is 32.
Wayne is going to send some flowers to his wife. Belmont Florist charges $1 per rose, plus $35 for the vase. Darrell's Flowers, in contrast, charges $2 per rose and $10 for the vase. If Wayne orders the bouquet with a certain number of roses, the cost will be the same with either flower shop. How many roses would there be? What would the total cost be?

the ordered pairs (0,-1),(1,0),(2,3),(3,8),(4,15) represents the function
Write an equation that represents the function. y =?
Answer:
y = x² - 1Step-by-step explanation:
y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula
If we add 1 to y-coordinate of every given point we get the squares of x-coordinate:
(1, 0): 1² - 1 = 0
(2, 3): 2² - 1 = 4 - 1 = 3
(3, 8): 3² - 1 = 9 - 1 = 8
(4, 15): 4² - 1 = 16 - 1 = 15
So for any x:
(x, y) y = x² - 1
The perimeter of a rectangle is 61 centimeters. The length is 4 centimeters longer than the width, w. Which equation can be used to find the width of this rectangle?
A= 2w + 2(w +4) = 61
B= 1/2w + 2 (w+4) =61
C=2w + 1/2 (w +4) =61
D= 1/2 w + 1/2 (w +4) =61
Answer:
A
Step-by-step explanation:
P=2L+2w
P=61
W=W
Since length is 4cm longer
Therefore length=W+4
General equation=2w+2(w+4)=61

What is Cos^-1( -sq2/2)? Pleaseee help ASAPOL
Answer:
s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant
Step-by-step explanation:
Take the integral:
integral cos^(-1)(-(q^2 s)/2) ds
For the integrand cos^(-1)(-(q^2 s)/2), substitute u = -(q^2 s)/2 and du = -q^2/2 ds:
= -2/q^2 integral cos^(-1)(u) du
For the integrand cos^(-1)(u), integrate by parts, integral f dg = f g - integral g df, where
f = cos^(-1)(u), dg = du, df = -1/sqrt(1 - u^2) du, g = u:
= -(2 u cos^(-1)(u))/q^2 + 2/q^2 integral-u/sqrt(1 - u^2) du
Factor out constants:
= -(2 u cos^(-1)(u))/q^2 - 2/q^2 integral u/sqrt(1 - u^2) du
For the integrand u/sqrt(1 - u^2), substitute p = 1 - u^2 and dp = -2 u du:
= -(2 u cos^(-1)(u))/q^2 + 1/q^2 integral1/sqrt(p) dp
The integral of 1/sqrt(p) is 2 sqrt(p):
= (2 sqrt(p))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for p = 1 - u^2:
= (2 sqrt(1 - u^2))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for u = -(q^2 s)/2:
Answer: = s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant
A turkey was cut into 10 equal pieces. If Katie ate 210 of the turkey, and Lorenzo ate 510 of the turkey, how many whole pieces of the turkey are left?
Answer:
3 Whole pieces
Step-by-step explanation:
A turkey was cut into 10 equal pieces.
For Katie
If Katie ate 2/10 of the turkey
Number of Whole pieces of turkey Katie ate =
2/10 × 10 whole pieces = 2 whole pieces
For Lorenzo
Lorenzo ate 5/10 of the turkey
Number of Whole pieces of turkey Lorenzo ate =
5/10 × 10 whole pieces = 5 whole pieces
how many whole pieces of the turkey are left?
This is calculated as:
10 pieces - (2 piece + 5 pieces)
10 pieces - 7 pieces
= 3 pieces
Therefore, we have 3 whole pieces of turkey left.
Answer:
3 Whole pieces
Step-by-step explanation:
A turkey was cut into 10 equal pieces.
For Katie
If Katie ate 2/10 of the turkey
Number of Whole pieces of turkey Katie ate =
2/10 × 10 whole pieces = 2 whole pieces
For Lorenzo
Lorenzo ate 5/10 of the turkey
Number of Whole pieces of turkey Lorenzo ate =
5/10 × 10 whole pieces = 5 whole pieces
how many whole pieces of the turkey are left?
This is calculated as:
10 pieces - (2 piece + 5 pieces)
10 pieces - 7 pieces
= 3 pieces
Therefore, we have 3 whole pieces of turkey left.

Cody bought two pairs of gloves and four hats for $43. Tori bought two pairs of gloves and two hats for $30. What are the prices for the gloves and hats? Write a system of equations!
Answer:
2g + 4h = 43
2g + 2h = 30
Step-by-step explanation:
Answer:
pairs of gloves = x
hats = y
2x + 4y = 43
2x + 2y = 30
hats = $6.50
gloves = $8.50
Step-by-step explanation:
use the elimination method to solve this system.
subtract the first equation by the second.
2x + 4y = 43
- 2x + 2y = 30
--------------------
2y = 13
y = 6.5
plug in the y value to find x
2x + 4 (6.5) = 43
2x + 26 = 43
2x = 17
x = 8.5
