Answer:

549.5 cm³

Step-by-step explanation:

___________________________________________________________

FORMULA USED IN THE QUESTION :-

Volume of a cylinder whose height is 'h' and radius is 'r' = [tex]\pi \times r^2 \times h[/tex]

___________________________________________________________

According to the question ,

Height of cylinder (h) = 7 cm

Radius of cylinder (r) = 5 cm

Volume of cylinder = [tex]\pi \times 5^2 \times 7 = 3.14 \times 25 \times 7 = 549.5 \: cm^3[/tex]

Answer:

113

Step-by-step explanation:

note: to find the circumference of a circle using the radius, you use this equation -- 2[tex]\pi[/tex]r. since the radius is 18, you make the equation 2[tex]\pi[/tex]18. that gets you 36[tex]\pi[/tex], which, if put into the calculator, is about 113.

Answer:

Step-by-step explanation:

1. 6f+45+15=180

6f=180-45-15

6f=130

f=130/6=65/6=21.66666666666666....

2. d=6f=130/6=65/6=21.66666666666666....

(They are vertical angles, opposite angles)

Answer:

R = 23 ohms

Step-by-step explanation:

Start with V = I*R.  Solve for R:  R = V/I

Here I = 8 amps and V = 184 volts, and so

R  = (184 volts) / (8 amps) = 23 ohms

Answer:

none or vertical

Answer: 4 gallons per day

Step-by-step explanation:

From the question, we are informed that the Snyder family uses up a 12 -gallon jug of milk every 3 days.

The rate at which they drink milk will be gotten by dividing the gallons of milk they drink by the number of days. This will be:

= 12/3

= 4 gallons per day

Therefore, the rate they use in taking milk is 4 gallons per day.

Answer:

it is within 5 minutes ahead or behind 5 minutes of 64 minutes

Answer:

$240.92

Step-by-step explanation:

From the question,

The distance traveled by the truck is directly proportional to the amount of petrol used.

I.e,

d ∝ v............... Equation 1

d = kv

d/v = k

d₁/v₁ = d₂/v₂............. Equation 2

Where d₁ and d₂ are initial and final distance respectively, v₁ and v₂ are initial and final amount of petrol used respectively.

Given: d₁ = 450 km, d₂ = 1050 km, v₁ = 35 liters

Substitute into equation 2 and solve for v₂

450/35 = 1050/v₂

v₂ = (1050×35)/450

v₂ = 36750/450

v₂ = 81.67 Liters.

If a liter of petrol cost $2.95,

Then,

81.67 liters will cost (81.67×$2.95) = $240.92

Step-by-step explanation:

Volume of the prism is the product of the base area and the height

Base area is:

Volume is:

Answer:

The base is representing a trapezium.

So,

Area = ½ × 10 × 3.6

Area = 5 × 3.6

Area = 18 m²

Now,

Volume = 5 × Area

Volume = 5 × 18

Volume = 90 m²

12x -36yz

Step-by-step explanation:

hope this helps!

Hello!

In order to simplify this expression, all we have to do is multiply 3 times the terms inside the parentheses:

3(4x-12yz)

12x-36yz

That's the final answer, because there are no like terms here, so we cannot simplify this expression any further.

Hope everything is clear.

Answer: C

In vertex form a(x - h)2 + k, values of a indicate the horizontal stretch/compression. From there just knowing that values less than 1 stretch the graph, while values greater than 1 compress it. Graphing it out on your own by simply inputting values into x will make this pretty clear.

Hope this helps!

Step-by-step explanation:

Answer:

Height of the house will reduce by 22 feet after 11 days.

Step-by-step explanation:

A house is sinking at the rate of 2 inches per day.

That means rate of sinking of the house is 2 inches in a day.

Therefore, house will sink or change in height of the house in 11 days

= Rate o change in height × Number of days

= 2 × 11

= 22 feet

Height of the house will reduce by 22 feet after 11 days.

Answer:

y=5

Step-by-step explanation:

16-11= 5.

Answer:

(x,y) = (-2,7)

Step-by-step explanation:

7x+2y=0

9x+4y=10

y = -9x/4 + 5/2

7x+2 (-9x/4 + 5/2) = 0

5x/2 = -5

5x = -10

x = -2

use x and substitute to get y

y = -(9/4) (-2) +5/2 = 7

Answer:

6/10

Step-by-step explanation:

hope this helps:) plz mark me brainliest

Answer:

3/5

Step-by-step explanation:

alrighty, so this is a standard rate and multiplication problem. How do we know? Well, because there's a steady rate of 2/10 per day, and for 3 days so:

2/10 x 3 = 6/10

6/10 can be simplified:

6/10 ÷ 2 = 3/5

So Daniel eats 3/5 yogurt over the course of 3 days

hope this helps:)

Answer:

B = 115

Step-by-step explanation:

Since A and B are supplementary, they add up to 180 degrees.

Thus, 65 + B = 180, and B = 115

Answer:

Certain

Step-by-step explanation:

The answer is certain because all the numbers on a cube are less than 7. So it's impossible to get a number more than 7, or equal to 7.

Answer:

71.77cm

Step-by-step explanation:

Answer:

71.76 cm^2

Step-by-step explanation:

The composite figure is made up of a rectangle with a missing half circle and a triangle.

area = area of rectangle + area of triangle - area of half circle

For the circle, radius = r = diameter/2 = 7 cm/2 = 3.5 cm.

area = LW + bh/2 - (pi)r^2/2

area = 10 cm * 7 cm + 7 cm * 6 cm/2 + (3.14)(3.5 cm)^2/2

area = 70 cm^2 + 21 cm^2 - 19.24 cm^2

area = 71.77 cm^2

Answer: 71.76 cm^2
