Answer:
n³ + 15n² + 56n
Step-by-step explanation:
The formula for the volume of a rectangular prism is V = l × w × h.
We are given the dimensions of this rectangular prism: n, n + 7, n + 8.
We can assume that these are the length, width, and height of the rectangular prism (not in any specific order).
Let's substitute these values into the formula to find the volume of the prism, written as a polynomial in standard form.
V = l × w × hV = (n) × (n + 7) × (n + 8) V = (n² + 7n) × (n + 8) V = n³ + 8n² + 7n² + 56n V = n³ + 15n² + 56nThe volume of the prism is n³ + 15n² + 56n. This is in standard form because the terms are listed in descending power order.
if $40 equals 15 gallons, how much money is in 3 gallos? this is due soon pls help
Answer:
$8
Step-by-step explanation:
$40:15 gallons
:3 gallons
So first you say what did you do to 15 to get three?
15÷3= 5
Now you divide forty by five since that is what you did to 15 to get three.
40÷5= 8
rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, a in seconds, by the given equation. Using this equation, find out
the time at which the rocket will reach its max, to the nearest 100th of a second.
y=16x^2+ +225x+79
Answer:
7.03 seconds
Step-by-step explanation:
First, you need to differentiate the equation (The derivative of y represents the rocket's velocity):
y' = 32x + 225
Then, set y' to 0 and solve for x
0 = 32x + 225
x = 7.03s
Can two obtuse angles be supplementary? Explain why or why not
Answer:
no
Step-by-step explanation:
No, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°. It will not satisfy the property of the supplementary angles when we add obtuse angles.
Answer: the answer is No
Step-by-step explanation: the answer is no because, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°. It will not satisfy the property of the supplementary angles when we add obtuse angles.

Rectangle 1 has length 10 and width 20. Rectangle 2 is made by multiplying each dimension of Rectangle 1 by a factor of k=3
Answer:
30cm, 60cm
Step-by-step explanation:
Given data
Dimensions of the first rectangle
Length =10cm
Width =20cm
We are told that the dimensions of the second rectangle is gotten by multiplying the first rectangle by 3
Hence the dimensions of the second rectangle is
Length =10*3= 30cm
Width = 20*3= 60cm
Any help please? (pre-algebra) Please provide an explanation, if not it’s fine but one would be appreciated.
Answer:
Option C
Step-by-step explanation:
Height of the rocket is modeled by,
h(t) = -16t² + 125t + 24
Height of the rocket in t = 0.1 seconds
h(0.1) = -16(0.1)² + 125(0.1) + 24
= -0.16 + 12.5 + 24
= 36.34 feet
At t = 5 seconds,
h(0.5) = -16(5)² + 125(5) + 24
= -400 + 625 + 24
= 249 feet
At t = 5.6 seconds,
h(5.6) = -16(5.6)²+ 125(5.6) + 24
= -501.76 + 700 + 24
= 222.24 feet
At t = 7.8 seconds,
h(7.8) = -16(7.8)² + 125(7.8) + 24
= -973.44 + 975 + 24
= 25.56 feet
Therefore, change in height is maximum at t = 5.6 seconds
Option C will be the answer.

The sum of 3 consecutive integers is 30.
What is the third number in this sequence?
Answer:
11
Step-by-step explanation:
the 3 numbers are 9, 10, 11
Answer:
Third number = 11
Step-by-step explanation:
Let 3 consecutive numbers be x ,x +1 , x +2
x +x+1 + x+ 2 = 30
x +x +x + 1 + 2 = 30 {Combine like terms}
3x + 3 = 30 {Subtract 3 from both sides}
3x = 30 - 3
3x = 27 {Divide both sides by 3}
x = 27/3
x = 9
Third number =x + 2 = 9 + 2 = 11

Find the area of the region shaded in green. Use 3.14 to approximate pi.
Answer:
254 cm² (to 3 s.f.)
Step-by-step explanation:
Area of shaded region
= area of large circle -area of smaller circle
[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]
Radius of large circle= 15cm
Radius of smaller circle= 12cm
Area of shaded region
= π(15²) -π(12²)
= 225π -144π
= 81π
= 81(3.14)
= 254.34
= 254 cm² (3 s.f.)

A delivery driver is traveling a total of 250 miles from a warehouse to a store at an average speed of 45 miles per hour. The function f(x)=250-45xf(x)=250−45x represents the distance remaining, in miles, after traveling for xx hours.
Answer:
115miles
Step-by-step explanation:
Given the function of the distance remaining represented by the function
f(x) =250-45x where;
x is the time taken in hours
Since we are not told what to loom for, we can calculate the distance remaining after 3hrs.
Substitute x =3 into the equation
f(3) = 250-45(3)
f(3) = 250-135
f(3) = 115
Hence the distance remaining after 3 hrs is 115miles

find the value of x
please help
Answer:
Here we can see that two lines are intersecting so that the angles formed will be vertically opposite angles,
Thus, the value of both angles will be equal
i.e., x+3 = 84
⇒ x = 84 - 3
⇒ x = 81
Thus the value of x is 81

Hallie made 12 quarts of homemade yogurt. She put the yogurt in 34-cup containers. How many containers did Hallie fill?
Answer:
1 container and 14 cups
Step-by-step explanation:
We know that 1 quart = 4 cups
therefore, 12 quart = 48 cups
each container has 34 cups
so one container would be full and remaining 48-34 =14 cups can be filled in another container.

the solution of the system is ( , ).?
Answer:
The solution of the system is (9,-8)
Step-by-step explanation:
2x+2y=2
3x-2y= 43
5x = 45
x = 9
2(9) + 2y = 2
18 + 2y = 2
2y = -16
y = -8
