Answer:

C. 1324.7 cm³

Step-by-step explanation:

Volume of cylinder = πr²h

π = 3.14

radius (r) = ½ of 15 = 7.5 cm

Height (h) = 7.5 cm

Plug in the values

Volume = 3.14*7.5²*7.5 = 1324.7 cm³

Answer:

15/8 minutes

Step-by-step explanation:

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

where k is a constant.

You are given a t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.  Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]

minutes.

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

We have given,

The time t  for am ice cube to melt. is inversely proportional to the

temperature T of the water in the ice cube is placed.

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

Where k is a constant.

You have given a  t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.

Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80} =\frac{15}{8}[/tex]

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

Answer:

x=1

Step-by-step explanation:

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

3x+8x-8 = 3

11x-8 = 3

11x = 11

x = 11/11 = 1

The solution for x in the expression 3x + 2 (4x- 4) = 3 is,

⇒ x = 1

The given expression is,

⇒ 3x + 2 (4x- 4) = 3

We can simplify by apply distributive property and combine like term,

⇒ 3x + 2 (4x- 4) = 3

Apply distributive property,

⇒ 3x + 8x - 8 = 3

Combine like term,

⇒ 11x - 8 = 3

Add 8 both side,

⇒ 11x = 3 + 8

⇒ 11x = 11

Divide by 11,

⇒ x = 11 / 11

⇒ x = 1

Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,

⇒ x = 1

Answer:

Step-by-step explanation:

You are given the equation g(x)=5x-2. You simply take the values given and put those values into the equation.

g(-4)=5(-4)-2=-20-2=-22

g(-7)=5(-7)-2=-35-2=-37

g(0)=5(0)-2=-2

g(23)=5(23)-2=115-2=113

g(38)=5(38)-2=190-2=188

Adult ticket : 6.5

Child ticket: 3

Answer: $150

Step-by-step explanation:

Becky spends 3/5 of her Money and is left with 2/5 of her money.

Hence 2 parts = $60

And 5 parts = $150

Becky has $150 at first.

Becky starts with $150.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Becky spends 3/5 of her money she has left £60 left.

let Becky earned be x.

so, x- 3/5x= 60

2x/5 = 60

x= 300/ 2

x=$150

Hence, Becky starts with $150.

Step-by-step explanation:

Step 1: Define Systems

4x - 3y = -20

-x - 8y = 5

Step 2: Rewrite Systems

-x - 8y = 5

Step 3: Redefine Systems

4x - 3y = -20

x = -8y - 5

Step 4: Solve for y

Substitution

Step 5: Solve for x

Answer:

x = -5

y = 0

Step-by-step explanation:

4x-3y=-20

-x-8y=5  then x = 8y-5

substitute for x

4(8y-5)-3y = -20

32y-20-3y = -20

29y = 0

y = 0

4x-0 = -20

x = -5

Answer:

  40 ft by 85 ft

Step-by-step explanation:

The total length of the three "vertical" partitions is ...

  3x = vertical partitions

The total length of the horizontal sides is ...

  2(x +(x +5)) = 4x +10

Then the perimeter is ...

  P = vertical partitions + horizontal sides

  290 = 3x +4x +10

  280 = 7x

  x = 40

  2x+5 = 85

The overall dimensions are 40 ft by 85 ft.
