Answer:
It is true that both cars are traveling at the same speed.
Step-by-step explanation:
Given that car A travels 20 miles over half an hour, we know that this car is traveling at a speed of 40 miles per hour.
Car B travels 30 miles in 3/4 of an hour, let us set up a proportion to solve whether or not Car B is traveling at the same rate as Car A
30 miles / (3/4 hour) = x miles / 1 hour Cross multiply
30 = (3/4) x Divide both sides by (3/4)
40 = x
Therefore, both Car A and Car B are traveling at the same rate.

Answer:
The answer is B
Step-by-step explanation:
3x - 2x^2 + 3 -(-5x^2 + 3x + 5)
3x - 2x^2 + 3 + 5x^2 - 3x - 5

Surface area of a triangular prism
Answer:
Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A=bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

a) Work out (8 x 10^-3)(2 x 10^-4
Give your answer in
standard form.
(
Answer:
1.6 x 10^-6.
Step-by-step explanation:
a) Work out (8 x 10^-3)(2 x 10^-4)
= 8 x 2 x 10^(-3 + -4)
= 16 x 10^-7
Convert this to standard form by dividing the first part by 10 and multiplying the second by 10.
= 1.6 x 10^-6.
Lines A and B have
the same y-intercept,
but different slopes.
Both slopes are
negative.
PARALLEL PERPENDICULAR OR NEITHER
Answer:
Neither
Step-by-step explanation:
Since line a and b have different slope, it isnt parallel, and since the slopes both negative, its not an opposite reciprocal, so that isnt perpendicular, thus leading to neither

Help PLSS Thanks ………………….
Answer:
3rd option
Step-by-step explanation:
Given z is inversely proportional to (y - 2)² then the equation relating them is
z = [tex]\frac{k}{(y-2)^2}[/tex] ← k is the constant of proportion
To find k use the condition when y = 5, z = 9 , then
9 = [tex]\frac{k}{(5-2)^2}[/tex] = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
81 = k
z = [tex]\frac{81}{(y-2)^2}[/tex] ← equation of proportion

The required solution to the given numerical expressions is 88.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
We have to determine the solution of 1.25 × 4 + 3 × 2 divided by (1/2) to the 3rd power
According to the given question,
⇒ (1.25 × 4 + 3 × 2) / (1/2)³
Apply the multiplication operation in the terms of the numerator,
⇒ (5 + 6) / (1/2)³
Apply the addition operation in the terms and expand the power of the denominator,
⇒ (11) / (1/8)
Reciprocal the term of denominator,
⇒ (11) × 8
⇒ 88

0.8 = 8/10
True
False
Answer:
true
Step-by-step explanation:
0.8 is out of 1.0 so 0.8 + 0.2 = 1.0 and same for 8/10
Answer: True
Step-by-step explanation:
In order to see if the two given numbers are equal to each other, you need to turn one of them into either a fraction or a decimal so both of them are the same and you are able to compare.
In order to turn [tex]\frac{8}{10}[/tex] into a decimal, you divide 10 by 8.
8 ÷ 10 = 0.8
Both of the decimals are the same therefore the numbers are equal to each other and the statement is true.
