Find two integers whose sum is 11 and product is 24
Step-by-step explanation:
if the two integers are x and y
x+y=11
xy= 24
x+24/x=11
x2-11x+24=0
(x-8)(x-3)=0
x =8 or x=3
if x=8,y=3
if x=3,y=8
so the two integers are 3 and 8

Monica estimates the recipe makes about 5 cups of fruit salad. Which explanation describes whether Monica's estimate is reasonable?
A Not reasonable. Four fractions cannot equal more than 4 cups.
B) Not reasonable. The whole numbers add up to 3 so the total sum cannot be 5 cups.
C с Reasonable. The grapes and apples is about 2 cups and pears and oranges is exactly 3 cups.
D Reasonable. The pears and apples is about 3 cups and the grapes and oranges is exactly 2 cups.
Answer:
A.
Step-by-step explanation:
Not reasonable, Why did you put that as your answer?
The whole numbers add up to more then 4 cups.
Ai Mi went to the store to buy some chicken. The price per pound of the chicken is $3.50 per pound and she has a coupon for $2.50 off the final amount. With the coupon, how much would Ai Mi have to pay to buy 3 pounds of chicken? Also, write an expression for the cost to buy pp pounds of chicken, assuming at least one pound is purchased.
Answer:
$8 for 3 pounds
cost for p pounds: 3.50p - 2.50
Step-by-step explanation:
Cost of 3 pounds:
Original cost = Cost per pound x 3
= 3.50 x 3
= 10.50
Coupon = 2.50
Final cost = Original cost - Coupon
= 10.50 - 2.50
= $8
Cost of p pounds:
Original cost = Cost per pound x p
= 3.50 x p
= 3.50p
Coupon = 2.50
Final Cost = Original Cost - Coupon
= 3.50p - 2.50

A 8-kg load stretches an elastic belt 0.02 m. How much will a 12-kg load stretch the belt?
Answer:
A 12-kg load stretches an elastic the belt 0.03m
Step-by-step explanation:
we know A 8-kg load stretches an elastic belt 0.02 m.
=> 0.02 / 8 = 0.0025
so A 1-kg load can stretch an elastic belt 0.02 m.
=> 12 * 0.0025 = 0.03 m
A 12-kg load stretches an elastic the belt 0.03m

•Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer. (2 pts.)
Answer:
answer should be 105 degrees.
Step-by-step explanation:
this is becuase the 75 degree angle given creates a 105 degree angle to its left. and the car turning left onto 3rd street would be a corresponding angle to the 105 degree angle on the top. sorry if its confusing, but the answer is 105 degrees. hope it helps
Answer:The angle formed by turning from traveling southwest on King Avenue to 3rd street is a corresponding angle to the 75° angle. This means its measure is 75°. here is your answer!

out with this problem please ?
Answer:
Step-by-step explanation:
If you are looking for the value of x, use the Pythagorean Theorem.
x² = 58² - 40² = 1764
x = √1764 = 42
Answer: 42cm
Step-by-step explanation:
Using the formula
(Hypotenuse^2)= (Opposite^2) + (Adjacent^2)
Hypotenuse= 58cm
Opposite= 40cm
Adjacent= x
Therefore
(58^2)= (40^2) + (x^2)
3364= 1600 + x^2
3364-1600= x^2
1764= x^2
x= 1764^1/2
x= 42
Adjacent= 42cm

Step-by-step explanation:
Why might algebra tiles not be a good tool to use to factor x2 + 18x + 80? Explain.
Step-by-step explanation:
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.
There are a lot of tiles to drag onto the board.
You would need to create a rectangle from 99 tiles.
80 is a multiple of 10, so it has factors of 10 and 8, which add to 18.

explain why the miniscus of mercury is bent upwards
Answer:
Step-by-step explanation:
A concave meniscus, which is what you normally will see, occurs when the molecules of the liquid are attracted to those of the container. This occurs with water and a glass tube. A convex meniscus occurs when the molecules have a stronger attraction to each other than to the container, as with mercury and glass.
if the height of cylinder 40cm and radius 10.5 find total surface and volume
Answer:
TSA of cylinder= 2πrh+2πr²
(2*3.14*40*10.5)+(2*3.14*10.5*10.5)
= 2,638.93+692.72
= 3,331.66
Volume= πr²h
= 3.14*10.5*10.5*40
= 13,854.42

The area of a square in square feet is repersented by
[tex] {z}^{2} + 12z + 36[/tex]
Find an expression for a side length of the square.
Find the perimeter of the square when z=12.
1. Find an expression for a side length of the square.
For this case, the first thing to do is to know that the area of a square is:
A = L ^ 2
Where
L: side of the square.
We then have to factorize the given polynomial:
z ^ 2 + 12z + 36
(z + 6) * (z + 6)
Rewriting:
z ^ 2 + 12z + 36 = (z + 6) ^ 2
Answer:
The side of the square is:
L = (z + 6)
2. Find the perimeter when z = 12.
The perimeter of a square by definition is:
P = 4L
Where
L: side of the square.
Substituting we have:
P = 4 (z + 6)
For z = 12 we have:
P = 4 (12 + 6)
P = 72
Answer:
the perimeter when z = 12 is:
P = 72

What is the extraneous solution of the given absolute value equation?
-2|-2x-4|=-12
9514 1404 393
Answer:
is no extraneous solution
Step-by-step explanation:
An absolute value equation typically does not have extraneous solutions. The solutions to this one are ...
x ∈ {-5, 1}
__
Unless there is some domain restriction, this equation has no extraneous solutions.
_____
For -2x-4 < 0
-2(2x +4) = -12
x +2 = 3
x = 1 . . . . . . -2(1)-4 = -6 < 0. Not an extraneous solution
__
For -2x-4 > 0
-2(-2x -4) = -12
4x +8 = -12
4x = -20
x = -5 . . . . . . -2(-5) -4 = 6 > 0. Not an extraneous solution
