What is the volume of the rectangular prism?
pls explain and thank you
Answers
Answer:
416 mm^3
Step-by-step explanation:
The equation for the volume of a rectangular prism is
[tex]Volume = Length * Width * Height[/tex]
We will use Length = 5 mm, Width = 10.4 mm, and Height = 8 mm
[tex]V = 5mm * 10.4mm * 8mm\\\\=416 mm^3[/tex]
Important things to note:
- The unit in the final answer is mm^3 because when you multiply "like terms" together, their exponents are added together
[tex]a^b*a^c*a^d\\\\= a^b^+^c^+^d[/tex]
Step by step explanation:
To find the volume you need to use this formula:
Length x width x height
So you need to do 10.4mm x 5mm x 8mm!
And that’s how you get the answer of 416mm!

Constance has an apple that weighs 85,000 milligrams and a peach that weighs 0.15 kilograms. Which fruit has the greater mass? Choose the words and numbers to complete the statements. Convert the masses of both fruits to the same unit.85,000 milligrams is the same as Choose... grams.0.15 kilograms is the same as Choose... grams. The Choose... has the greater mass.
Answers
Step-by-step explanation:
it is important to understand the meaning of the syllables in the terms :
kilo means 1000
milli means 1/1000
so, 1 kg means 1000 g (grams).
1 mg means 1/1000 g.
therefore,
85,000 mg = 85 g = 0.085 kg
0.15 kg = 150 g = 150,000 mg
so, it is clear that the peach has the greater mass.

The percent of voters between the ages of 18 and 29 that participated in each United States presidential election between the years 1988 to 2016 are shown in the table.
The function P gives the percent of voters between 18 and 29 years old that participated in the election in year t.
Determine the average rate of change for P between 1992 and 2000.
Do not include units (%) in your answer.
Round your answer to the nearest thousandth.
Answers
Answer:
2,4
Step-by-step explanation:
The average rate of change for P between 1992 and 2000 is -1.025.
What is Average rate of change?Average rate of change function is the average rate by which a quantity is changed with respect to another quantity.
It can be calculated as the amount of change in a quantity divided by the amount of change in another quantity.
Average rate of change for a function 'f' in the interval [a, b] is,
A = [tex]\frac{f(b) - f(a)}{b - a\\}[/tex]
Here P is the function which is the percent of voters between ages 18 and 29 in the interval 1992 to 2000
Average rate of change for P = P(2000) - P(1992) / 2000 - 1992
A = [34.5 - 42.7] /[2000 - 1992]
A = -8.2 / 8
A = -1.025
Hence, the average rate of change for P between 1992 and 2000 is -1.025.

Answers
The length of the rectangle is 15 feet.
What is Rectangle?Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles.
Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given that,
Area of a rectangle = 120 square feet
Width = 8 feet
Let length of the rectangle be x.
We know that,
Area of a rectangle = Length × Width
8x = 120
x = 120 / 8 = 15 feet
Hence the length of the rectangle is 15 feet.

The percent decrease in the population is 12%
What is a percent?Percentages are essentially fractions where the denominator is 100.
Given that, the population of a city was 51,000. Several years later it was 44,880.
We are asked to find percent decrease,
Percent decrease = Final element - initial element / initial element x 100
Percent decrease = 44880 - 51000 / 51000 x 100
= -6120 / 51000 x 100
= --0.12 x 100
= -12%
Here, - sign is showing the decrease.
