The volume of prism A is 60 cubic units, and the volume of prism B is half the volume of prism A. What is the value of a?

Answer: Isosceles Triangle

Step-by-step explanation:

Looking at this problem, we can easily say this this is a right triangle, by looking at the labeled angle. This questions asks for you to look at the angles and side lengths. Because the sides are both equal in length, this is an isosceles triangle.

Answer:

52

Step-by-step explanation:

If ABCD ~ EFGH

AND AB = 15 and EF = 18 and ABCD = 40

then

each side of ABCD should be 3cm less then side of EFGH

AB + BC + CD + DA = 40

AB + 3 + BC + 3 + CD +3 + DA + 3= P(EFGH)

40+12 = 52 = P(EFGH)

Answer:

Scientific notation simply refers to the process of expressing long numbers in decimal.

Answer:

Step-by-step explanation  

Scientific notation is a way of writing numbers that is often used by scientists and mathematicians to make it easier to write large and small numbers. A number that is written in scientific notation has several properties that make it very useful to local scientists. It makes very large numbers into smaller numbers using decimals and exponents.

Answer:

250+20 = 270 cents or $2.70

Step-by-step explanation:

Each quarter is 25 cents

Each dime is 10 cents

Answer:

230

Step-by-step explanation:

Okay, so if Lidia got 75% means that Henry got 25%, right?

Then Lidia got 50% more than Henry did. So that 460 = 50%

So Henry got 25% which is 460/2 = 230 snow globes

Answer:

A1= 10×15=150

A2= 5²×3.14/2=39.3

so the A total is 150+39.3=189.3

Answer: 0.12

Step-by-step explanation:

An exponential decay can be written as:

C(t) = A*r^t

Where A is the initial amount of cookies, A = 100

r is the rate that we are searching.

t is time in minutes, we know that at t= 0m

C(0) = 100*r^0 = 100

so at t = 0m we have 100 cookies.

now, we know that at t = 15m we have.

C(15s) = 100*r^(15m) = 15

r^15 = 15/100 = 0.15

r = (0.15)^(1/15) = 0.88

So the rate at which the cookies decrease is 0.88, and 1 - r = 0.12 is the rate at which the kids eat the cookies (meaning that the students ate 12% of the cookies per minute), so the answer is 0.12

Answer:

The depth of oil in the tin is 9cm

Step-by-step explanation:

The first thing we need to do here is to calculate the volume of the cylindrical tin.

Mathematically, that would be;

V = pi * r^2 * h

now, r = d/2 = 12/2 = 6cm

h = 14 cm

Thus the volume would be;

V = 22/7 * 14 * 6^2 = 1,584 cm^3

Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.

Now let’s say the height of the tin is x, this means its volume which is l * b * h = 16 * 11 * x = 176x

So the depth x would be;

176x = 1584

x = 1584/176 = 9 cm

Answer:

16x+5

Step-by-step explanation:

First, we have to distribute.

2(5x+4)+3(2x-1)

2(5x)+2(4)+3(2x)+3(-1)

10x+8+6x-3

Combine Like Terms

10+6x+8-3

Answer:

They sold 120 milkshakes.

Step-by-step explanation:

Step-by-step explanation:

x³ - 4x = 0

x (x² - 4) = 0

x (x + 2) (x - 2) = 0

Thus the answer is (b) (-2 , 0) , (0 , 0) , (2 , 0)

Answer:

Step-by-step explanation:

This models the standard form of an exponential equation:

[tex]y=a(b)^x[/tex], where a is the intial value and b is the growth rate. The number in our function that holds position a is 1200. So the initial population is 1200.

Answer:

[tex]3x-7y[/tex]

Step-by-step explanation:

[tex]9x-7y-6x[/tex]

[tex]9x+-7y+-6x[/tex]

[tex]9x+-6x+-7y[/tex]

[tex]3x+-7y[/tex]

Answer:

3x-7y

Step-by-step explanation:

9x and 6x are like terms

We subtract 6x from 9x because it is a negative

9x-6x= 3x

7y is also negative that's why the answer is 9x-7y

But you can also do -7y + 3x

It doesn't matter it's still the same

Description:

The base of the prism is a square with sides measuring 5 cm, so its area is

(5cm)*(5cm)= 25 square cm

So the volume of the prism, in cubic cm, is

25*12=300

The volume of a pyramid is (1/3)(area of base)(height) .

It is 1/3 of the volume of a rectangular prism with the same base and height.

So the volume of the pyramid in this problem, in cubic cm, is

1/3*300=100

So the volume of the space outside the pyramid but inside the prism, in cubic cm, is

300-100= 200

Answer: =200

Answer:

g(x)=2(x-4)(x+3)​

Step-by-step explanation:

Answer:

Hello,

g(x) = 2 (x + 3) (x - 4)

Step-by-step explanation:

g(x) = 2x²- 2x - 24​

⇔ g(x) = 2 (x² - x - 12)

⇔ g(x) = 2 ((x - 1/2)² - (1/2)² - 12)

⇔ g(x) = 2 ((x - 1/2)² - 12.25)

⇔ g(x) = 2 ((x - 1/2)² - 3.5²)

⇔ g(x) = 2 ((x - 1/2)² - (7/2)²)

⇔ g(x) = 2 (x - 1/2 + 7/2) (x - 1/2 - 7/2)

⇔ g(x) = 2 (x + 3) (x - 4)

Answer:

Step-by-step explanation:

To find the value of x, solve the equation. Do this by rearranging the equation to make x the subject.

Answer:

x=32761 /4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+7=32768

Step 2: Subtract 7 from both sides.

4x+7−7=32768−7

4x=32761

Step 3: Divide both sides by 4.

answer 19-11+(-17)+(-19)+11= -17

Step-by-step explanation:

Answer:

y = 2x or x = 1/2y or if you would like numerical values then x = 3, y = 6 and z=4

Step-by-step explanation:

x : y = 1 : 2

y : z = 3 : 2

If x : y = 1 : 2 then we know that 1y = 2x ∴ y = 2x or x = 1/2y

If y : z = 3 : 2 then we know that 3z = 2y ∴ z = 2/3y

Answer:

I think y is 2 as well as 3
