Answer:1072.3

Step by step:

use the hemisphere formula which is 2/3*pie*r^3

substitute 8 centimeters into the equation.

The Volume of a hemisphere is,

⇒ Volume of hemisphere = 1071.78 cm³

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Radius of hemisphere = 8 centimeters

We know that;

Volume of hemisphere = 2/3 (πr³)

Hence, We get;

⇒ Volume of hemisphere = 2/3 × 3.14 × 8³

⇒ Volume of hemisphere = 1071.78 cm³

Thus, The Volume of a hemisphere is,

⇒ Volume of hemisphere = 1071.78 cm³

Answer:

120

Step-by-step explanation:

The rules of multiplication state, that when there are two negatives being multiplied by each other, they become positive. You will multiply -10 x -12, and since there are two negatives, they cancel out.

Now it becomes simple multiplication. Simply multiply 10 x 12, without the negatives since they have been canceled out.

-10 x (-12) = 120

Answer:

x=-1

y=15

Step-by-step explanation:

This works because completing the square is essentially demonstrating what g(x)  - where g(x) in this case = x^2 - would have to be translated by to give the function you have.

So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.

Answer:

13

Step-by-step explanation:

Given data

flat amount =$10

let the number of dogs walked be x

and let the money earned be y

y= 10+5x

for y= 75

let us find x

75= 10+5x

75-10= 5x

65= 5x

divide both sides by 5

x= 65/5

x=13

Hence the number of dogs is 13

Answer:

x = 12

Step-by-step explanation:

Formula for area of a triangke is;

A = ½bh

Where;

b is base

h is height

From the triangle diagram given;

b = x + 6

h = x

Thus;

A = ½(x + 6)x

A = ½x² + 3x

Now we are told that the area is 108 m², Thus;

½x² + 3x = 108

Multiply through by 2 to get;

x² + 6x = 216

x² + 6x - 216 = 0

Using quadratic formula, we arrive at;

x = -18 or 12

x can't be negative, thus; x = 12

Answer:

362.35N/m²

Step-by-step explanation:

Pressure = Force/Area

Area = πr²

Area = 3.14(0.75)²

Area = 3.14(0.5625)

Area = 1.76625m²

Force = 640N

Pressure = 640/1.76625

Pressure = 362.35N/m²

Answer: She has enough.

Step-by-step explanation:

You need to add up the quantities of water needed first. That will then tell if she has enough water.

Convert the fractions to decimals then add them up:

3/8 = 0.375

1/4 = 0.25

= 0.25 + 0.375

= 0.625 cups of water is required.

This is less than the 1 cup she has so she has enough water to make the snack.

Answer:

option 3

Step-by-step explanation:

Δ AEB and Δ ADC are similar, so ratios of corresponding sides are equal, that is

[tex]\frac{AB}{AC}[/tex] = [tex]\frac{AE}{AD}[/tex] , substitute values

[tex]\frac{9.2}{AC}[/tex] = [tex]\frac{9}{14}[/tex] ( cross- multiply )

9AC = 128.8 ( divide both sides by 9 )

AC ≈ 14.3 (to the nearest tenth )
