Step-by-step explanation:

It is halfway between -3 and -4

Answer:

Michelle = 25

Alyssa = 13

Amanda = 9

Step-by-step explanation:

         We will set up equations for this problem to help us solve this problem mathematically. Let x be Alyssa, y be Michelle, and z be Amanda.

    [] Alyssa is 12 years younger than Michelle.

x = y - 12

    [] Michelle 25 ()is 7 years older than twice Amanda's age.

y = (2x) + 7

    [] The sum of all three ages is 47.

x + y + z = 47

    You gave that y = 25,

Michelle is 25.

    Since we know that Alyssa is 12 years younger than Michelle, we can solve for Alyssa.

x = 25 - 12

x = 13

Alyssa is 13.

    Lastly, the sum of all three ages is 47.

x + y + z = 47

13 + 25 + z = 47

z = 9

Amanda is 9.

The coordinates of vertex A' are (-2, 1)

The coordinates of vertex B' are (-3, 3)

The coordinates of vertex C' are (-1, 3)

Answer:

Vertex A is (-2,1)

Vertex B is (-3,3)

Vertex C is (-1,3)

Step-by-step explanation: When finding Vertex, all you nees to do is find the ordered pairs. Ordered pairs are a set of numbers that are graphed at certain numbers on the x-axis and the y-axis. To find ordered pairs, start with the x-axis (the horizontal line) and find what number it is on. Then use the y-axis (the vertical line) and find what number the point is on.

I am a high schooler and I know that math is hard. Just keep a positive mindset and power through it. You got this!

Answer:

(4/3)×3×4^3=256

Step by Step Explanation:

First, replace all the letters and signs with number, which will look like (4/3)×3×4^3. The r in the equation means radius and radius is half of the diameter (which is the 8), so that means the r is 4. Then, on your calculator, type in (4/3)×3. you should get 4. then take the 4 and muktuplmultiple

Answer:

256cm³

Step-by-step explanation:

Answer:

The parabola is translated down 2 units

Step-by-step explanation:

Look at the picture below

Red = F(x) = 2x^2 -5x +3

Blue = F(x) = 2x^2 -5x +1

as you can see the parabola is translated down 2 units

id say a and d but i dont know about b

Step-by-step explanation:

616 ÷ 22=28

480 ÷ 17=28.2352941176

224 ÷ 18=12.4444444444

784 ÷ 28=28

Answer:

$1187.22

Step-by-step explanation:

The balance was $1568.45 on 1/18 then she decided to withdraw $765.23 on 1/30, so we subtract 765.23 from 1568.45 which is 803.22 but then she added $384 to the account on 2/7 so we add 384+803.22 which equals to $1187.22, which would be the total balance on her account.

Answer:

$1,187.22

Step-by-step explanation:

After all of the Transactions, she will end up with $1,187.22

$1,568.45-$765.23= 803.22

$803.22+384=$1,187.22

Answer: $1,187.22

Answer: [tex]V=47,721.9in^3[/tex]

Step-by-step explanation:

The volume of a hemisphere would be 1/2 of the volume of a sphere. The volume of a sphere is defined to be:

[tex]V=\frac{4}{3} \pi r^3[/tex]

Therefore the volume of a hemisphere would be:

[tex]V=\frac{1}{2}( \frac{4}{3} \pi r^3)=\frac{2}{3} \pi r^3[/tex]

Plug everything in:

[tex]V=\frac{2}{3} \pi r^3=\frac{2}{3} \pi (28.35)^3=47,721.9in^3[/tex]

Answer:

46 minutes

Step-by-step explanation:

Answer:

47 minutes

Step-by-step explanation:

from 3:37 to 4:00 is 23 minutes

Answer:

False

Step-by-step explanation:

An independent event is an event in which the outcome isn't affected by another event.

Answer:

the answer for this one should be the second choice s=7t because first of all you have to divide 21 and 3 and the answer you get is 7 for everything so choice c could not be neither d and a so b is the answer.

Answer: 16/3 (written as a fraction)

Step-by-step explanation:

14=(3*x)-2

x=16/3

Answer:

Step-by-step explanation:

To find the Scale factor we use this formula:

Scale factor / K  = Dimension of the new shape ÷ Dimension of the original shape

Substitute any 2 corresponding sides into the formula:

I took 1 and 4:

K = 1 / 4

K = 0.25

I'm not sure which form the question is so I will leave it here.

Hope this helped. Brainliest please?

Answer:

4:1

Step-by-step explanation:

its ask from A to B

A is the bigger

if you divide a side from the bigger one

by the same side of the smaller one you'll get 4

6÷1.5 = 4

4.4÷1.1 = 4

4÷1 = 1

Answer:

The area of a trench is 5.5 m² .

Step-by-step explanation:

Formula

Area of a rectangle = Length × Width

As given

Tanya has a garden with a trench around it.

i.e

Put in the above formula

                            = 5 m²

As given

i.e

                                                 = 10.5 m²

Area of the trench = Area of garden with trench - Area of garden

Put the value in the above

Area of the trench = 10.5 m² - 5 m²

                              = 5.5 m ²

Therefore the area of a trench is 5.5 m² .

Answer:

[tex]2\pir[/tex]

2 × 22/7 ×4

8×22/7

25.136ft

25.14ft

To solve this problem,

    ⇒ must use PEMDAS and fractional conversions

        ⇒ I attached an image of what is PEMDAS below

Let's solve:

  [tex]2(x+7)-18x+\frac{4}{5} =2x+14-18x+\frac{4}{5} =14-16x+\frac{4}{5}[/tex]

  Here we convert 14 into a fraction with a denominator of 5 so that we

  can add it to 4/5

  [tex]14*1-16x+\frac{4}{5} =14*\frac{5}{5} -16x+\frac{4}{5} =*\frac{14*5}{5} -16x+\frac{4}{5} \\=\frac{70}{5} -16x+\frac{4}{5} =\frac{70}{5} +\frac{4}{5} -16x=\frac{70+4}{5}-16x\\ =\frac{74}{5} -16x=-16+\frac{74}{5} \\=-16+\frac{74}{5}[/tex]

Answer: Thus the expression equivalent to the function given is (C)
