The statement is false because not all the corresponding point have been translated correctly from the original.

Here are the correct answers:

C: (-3, 1) to (0,5). CORRECT!
D: (1,5) to (4, 9) INCORRECT IN THE CHOICE
E: (5, 1) to (8, 5) INCORRECT IN THE CHOICE
F: (1, -3) to (4, 1) INCORRECT IN THE CHOICE

Answer:

Answer in terms of π=144π m^3

Answer by replacing π with 3.14 is 452.16 approximately 452.2m^3

Answer to the nearest whole no. is 452m^3

Step-by-step explanation:

$volume \: of \: a \: cone = \frac{1}{3} \pi {r}^{2} h$

$radius = \frac{diametre}{2}$

$radius = 24$

$height = 18$

$slant \: height \: = 30$

$first \: step$

$the \: exact \: volume \: of \: the \: cone \: in \: terms \: of \: \pi$

$v = \frac{1}{3} \pi {r}^{2} h$

$\: \: = \frac{1}{3} \times \pi \times 24 \times 18$

$\: \: \: = \frac{432\pi}{3}$

$\: \: \: = 144\pi$

$second \: step$

$approximate \: answer \: using \: 3.14 \: in \: place \: of \: \pi$

$144 \times 3.14$

$= 452.16$

$approximately \: 452.2$

$last \: step$

$answer \: to \: the \: nearest \: whole \: number$

$452 {m}^{3}$

5v– 1/2 =4+ 3/2 v<br><br> How does one person solve this if the like terms are on opposite sides?

Fofino [41]

Answer:

Step-by-step explanation:

Given

$5v - 1/2 = 4 + 3/2v$

Required

Solve

We have:

$5v - 1/2 = 4 + 3/2v\\$

Collect like terms

$5v - 3/2v = 4 + 1/2$

Express fractions as decimals

$5v - 1.5v = 4 + 0.5$

$3.5v = 4.5$

Make v the subject

$v= \frac{4.5}{3.5}$

Divide by .5

$v= \frac{9}{7}$

A stray dog 18 of your muffins. That was 2/3 of them . With how many did u start with

White raven [17]

27 because half of 18 would be 1/3 of your muffins, 1/3 of the muffins is 9 and add that third to the 2/3 and you're back to your original amount.

Ammar hikes 2 3/4 miles of nature trail in 1 hour and 15 minutes. How many miles of trail does Ammar hike per hour?

krok68 [10]

2 3/4 miles in 1 hour and 15 minutes.
To makes things simpler , the fraction for miles will be converted into an improper fraction, so it will be 11/4.
For the time, there is 60 minutes in one hour, so 60 plus the 15 minutes is 75.

Now that the numbers are simpler, we can start to create cross products.

In 11/4 miles it takes 74 minutes. How many in 60 minutes ? So to find that, take 11/4 over x equals to 75 over 60. Cross multiply:
11/4 * 69 = 165
75 * x = 75x
The equation is now 75x = 165
Divide 75 in both sides to isolate variable x.
x = 2.2
2.2 in fraction form is 2 1/5 .
So finally it takes Amman to walk 2 1/5 miles per every hour.
