Answer:
Step-by-step explanation:
(5d^4 - 8)^2
This is a perfect square.
Note an exponent multiplied by an exponent is the addition of them so
d^4 X d^4 = d^8
or
(d^4)(d^4)=d^8
h(x) = -(x + 3)(x - 2)
Answer: To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (−3,0),(2,0)
y-intercept(s): (0,6)

2x+10=2(x-5)
-2(x+5)=2x-10
-2x-10=-2(x+5)
-2(x-5)=-2x-10
Answer:
Third
Step-by-step explanation:
First would be, simplified, 2x+10=2x-10
Second, simplified, -2x-10=2x-10
Third, simplified, -2x-10=-2x-10
Fourth, simplified, -2x+10=2x-10
So it's third :)

for each serving, how many servings can be made from one pint?
1 gallon 4 quarts
1
quart
2 pints
1 pint = 2 cups
1 cup = 8 fluid ounces
Before you try that problem, answer the question below.
How many cups will you need to find the number of
servings for?
Answer: 4 servings
4 cups of milk = 8 servings
2 cups of milk = 4 servings
I divided both sides by 2 to change "4 cups milk" into "2 cups milk".
The reason why I want 2 cups of milk is because the chart you're given shows 1 pint is 2 cups.
Therefore, 1 pint of milk will get you 4 servings.

Answer:
sorry to answer as I kinda want the points
for me when problem solving it gave me 10%
as I'll show the work and why
Step-by-step explanation:
first dividng the two will make it clear
300,000/30,000
will give you
10 x%
30,000 will make it as 90% since it's 1/10 away from 30,000
300000 is 100% since it is our output value.
so 100% / 300,000
so x% / 30,000
300000(1) = 100%
x% / 30,000(2)
x%/30,00
100%/300,000

Step-by-step explanation:
In the xy-plane, the point (p,r) lies on the line with equation y=x+b, where b is a constant. The point with coordinates (2p,5r) lies on the line with equation y=2x+b. If p≠0, what is the value of r/p?
A)
2/5
B)
3/4
C)
4/3
D)
5/2
Answer:
hi
Step-by-step explanation:
I'm anmol kulkar from India thanks for free points by
Answer:
The correct answer is B,
3/4.
Step-by-step explanation:
choices A and D, you may have incorrectly formed your answer out of the coefficients in the point (2p,5r). If you picked Choice C, you may have confused r and p.
y=2x+b gives:
5r=2(2p)+b
5r=4p+b
b = 5r−4p.
Next, we can set the two equations equal to b equal to each other and simplify:
b=r−p=5r−4p
3p=4r
Finally, to find
r/p
divide both sides of the equation by p and by 4:
3p=4r
3=4r/p
3/4=r/p
Which expression gives the best estimate of 45 percent of 76?
One-fourth (80)
One-fifth (80)
One-half (80)
StartFraction 1 Over 9 EndFraction (80)
Answer:
1/2 of 80Step-by-step explanation:
45% is close to 1/2 (50%) and 76 is close to 80, so 1/2 of 80 is the best answer.
1/2 of 80 is 40
45% of 76 is 76 x 0.45 is 34.2
Answer:
1/2 of 80

v= u + at
u=2 a= -5 t=1 half
What’s the value of v?
Answer:
Prime number
Step-by-step explanation: because it doesn't have a value so yeah its a prime number.
Answer:
V = 0.5
Step-by-step explanation:
V = u + at
If U = 2, a = -5, and t = 1/2, then you can replace these in the equation to make the equation: V= 2 + (-5 x 1/2)
Solve the parenthesis first. -5 times 1/2 is -2.5.
Now the equation is V= 2 + -2.5
Simplifying that even more, 2 + -2.5 is 0.5
Therefore, V = 0.5

Andrew needs a ladder to hang holiday lights. His house is 24 feet tall and he has a flower bed that extends 4 feet out from the side of the house. How long of a ladder will he need to reach the top and be out of the flower bed?
Answer:
24.33 feet
Step-by-step explanation:
The flower bed, the ladder and the house form a right angled triangle where the length of the ladder is the hypotenuse side.
Let L = length of ladder, H = height of house = 24 feet and l = length of flower bed = 4 feet.
Using Pythagoras' theorem,
L² = H² + l²
So, L = √(H² + l²)
substituting the values of the variables, we have
L = √[(24 ft)² + (4 ft)²]
L = √[576 ft² + 16 ft²]
L = √[592 ft²]
L = 24.33 ft
The ladder must be at least 24.33 feet long to reach the top and be out of the flower bed

Mrs. Jones is creating a seating chart for the front row of her classroom. She has 10 possible students to place in the front row. If there are 30,240 different for the seating chart, how many seats are in the front row?
Answer:
5 seats
Step-by-step explanation:
if I'm getting the right idea, the seats are NOT enough
since the number of arrangement of 10 people in a row is
10! = 3628800 which is a lot larger than 30240.
---------------------------------------------------------------------------------------
Let number of seats be
10PX = 30240
[tex]\frac{10!}{(10-X)!}[/tex] = 30240
(10-X)! = [tex]\frac{10!}{30240}[/tex]
(10-X)! = 120
(10-X)! = 5!
10-X = 5
X = 5

A cylindrical tank has a radius of 5.5 ft and an altitude of 16 ft. If a gallon of paint will cover 130ft^2 of surface, how much paint is needed to put two coats of paint on the entire surface of the tank?
Answer:
Approximately 11 gallons of paintStep-by-step explanation:
First we need to calculate the Total surface area of the cylindrical tank as shown;
TSA of the tank = 2πr² + 2πrh
TSA of the tank = 2πr(r+ h) where;
r is the radius of the tank
h is the height
Given
radius = 5.5ft
height = 16ft
Get the surface area;
TSA = 2π(5.5)(5.5+ 16)
TSA = 2π(5.5)(21.5)
TSA = 2π(118.25)
TSA = 2(3.14)(118.25)
TSA = 742.61ft²
If a gallon of paint will cover 130ft^2 of surface, then the total number of paint needed will be;
Total number of paint needed = 742.61/130
Total number of paint needed = 5.7
For one coat we will need 5.7gallons of paint
For two coats we will need 2 * 5.7gallons = 11.4
Hence approximately 11 gallons of paints will be needed for the two coats
