(1) {(1,2), (3,4),(4,5), (5,6)}
(2) {(3,1),(2,1),(1,2), (3,2)}
(3) {(4,1),(5,1),(6,1),(7.1)}
(4) {(0,0), (1,1),(2,2), (3,3)}

Answer:

the answer is x= 2,-4

Step-by-step explanation:

zeros = 2, -4

Answer: 1/4

Step-by-step explanation:

Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:

= ⅜ + ½ + ¼

= 3/8 + 4/8 + 2/8

= 9/8

= 1 1/8

Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:

= 1/4 + 3/8 + 1/4

= 2/8 + 3/8 + 2/8

= 7/8

The numybe of paint that Destiny use more than Carla will be:

= 1 1/8 - 7/8

= 2/8

= 1/4

Destiny used 1/4 paint more than Carla

Answer:

126

Step-by-step explanation:

trust

Answer:

if your base is 14 and your height is 18 or the other way around then its:

14 x 18 = 252

252 divided by 2 = 126

Step-by-step explanation:

Formula of a triangle:

BH x 1/2 (basically dividing by 2)

B is your base which is the length on the bottom of the triangle and the height is the line that is put in between the triangle. You multiply those then divide by 2 since your multiply 2 with it.

Answer:

F

Step-by-step explanation:

The x and y do not match up

Answer:

It is F.

Step-by-step explanation:

It is F because all the x's are the same as that cannot happen.

Answer:

A. 20

Step-by-step explanation:

Firstly, you have an equation  where x is unknown.

It is said to find the result of this equation if x is 5.

That means you have to substitute 5 instead of x in your equation.

That will be:

3*5+4*5-15

When you calculate that, you get number 20.

Answer:

72

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

you divide 140 by 5 so 28 is the answer

B .28cm

Step-by-step explanation:

if 1cm=5m

then,140=×

1cm=5cm

cross multiply to get;

140÷5=28(cm)

=28cm

Answer:

Ralph walked to Sherwood at a constant speed.

Step-by-step explanation:

Any horizontal lines on a distance time graph represent a moment where you are still, so that rules out graph 4 and graph 3. Because Ralph is at a constant speed, the gradient of the line won’t change, meaning the answer has to be Ralph walked to Sherwood at a constant speed.

IS the formula for square pyramid.

Answer:

The formula for a lateral area formula of a square pyramid:

2a√((a^2/4)+h^2)

a = is the base

h = height of triangle

Answer:

A. (-4, -4)

Step-by-step explanation:

According to the word problem, a dilation of (0.75x, 0.75y) is applied to a triangle.

This means the original coordinates were enlarged/multiplied by 0.75.

We can multiply the coordinates at the bottom by 0.75 to see if we get any of the resulting images' coordinates.

OR

We could divide the resulting images' coordinates by 0.75 to see if we get any of the answers on the bottom.

For instance,

(-3, -3)

-3 / 0.75 = -4 (x-coordinate)

-3 / 0.75 = -4 (y-coordinate)

This means (-4, -4) were the original coordinates of (-3, -3) before the dilation of 0.75.

Answer:

5.73cm

Step-by-step explanation:

r=C/2pi=36/2*pi=5.73

Answer:

5.73 cm

Step-by-step explanation:

[tex]C=2\pi r[/tex]

Plug in the circumference 36 cm

[tex]36=2\pi r[/tex]

Divide both sides by 2π

[tex]\frac{36}{2\pi }=\frac{2\pi r}{2\pi } \\5.73=r[/tex]

Therefore, the radius of the circle is approximately 5.73 cm.

Step-by-step explanation:

[tex]\angle TPR=8x+7-75=360-150-91-75\\8x=112\\x=14[/tex]

Answer:

Step-by-step explanation:

Given :

Using cosine rule :

c² = a² + b² - 2abCosC

c² = 45² + 25² - 2(45)(25) - cos70

c² = 2650 - 2250 * - 0.3420201

c² = 2650 + 769.54532

c² = 3419.5453

c = sqrt(3419.5453)

c = 58.476

c = 58.5 feets

Answer:

Angle RUS = 160°

Step-by-step explanation:

Angle QUT is 160, and since angles QUT and RUS are vertical angles, they are congruent to each other.

So, Angle RUS = 160°

Answer:

first: 140

second: 9

third: 19

Step-by-step explanation:

the first question is x=140 because they are opposite angles.

second is also opposite so 4x=36, x=9

third is also opposite so 4x+5=81, 4x=81-5, x=19

Answer:

  -3x³y∛9

Step-by-step explanation:

The expression can be simplified by removing perfect cubes from under the radical.

  [tex]\sqrt[3]{-243x^9y^3}=\sqrt[3]{(-3x^3y)^3\cdot9}=\boxed{-3x^3y\sqrt[3]{9}}[/tex]

It helps to realize that 243 = 3^5 = (3^3)(3^2).

Answer:

Length = 75 ft

Width = 72 feet

Volume = 32,400 ft3

Water is around 242,998 gallons

Step-by-step explanation:

Just convert the yards to feet

25 yards long = 75 ft in length

8 lanes * 3 yards wide = 24 yards = 72 feet wide

And then for the volume, since it's a swimming pool, the formula will be l*w*h, and if we plug in the numbers (75 * 72 * 6 (it's 6 because they said the depth was six and in a pool the depth = height)) and that'll equal 32,400 ft to the third power

For the water, we just have to multiply the volume by 7.5 gallons by converting 7.5 gallons to feet, and then multiplying that by the volume, and then converting that to feet, and the final answer is about 242,998 gallons

Answer:

Length; 75 ft  

Width; 72 feet  

Volume; 32,400  

Water is around 243k gallons

Answer:

SA= 222cm ^2

Step-by-step explanation:

Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)

Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8

                                      = 30

Area of the base = 8×5 - 2×2 = 36 cm²

Surface area of the prism = 30×5 + 2×(36)= 222 cm²

Answer:

60in

Step-by-step explanation:

Given data

Length= 24 in

Width = 18 in

Diagonally, we need to find using the Pythagoras theorem

D^2= L^2+W^2

D^2= 24^2+18^2

D^2= 576+324

D^2= 900

Square both sides

D= √900

D= 30 in

For both sides

=30*2= 60in

Answer:

(-2, 1)

Step-by-step explanation:

consider the following equations: -x-y=1 y=x+3

For the lines to intersect, the  values must be the same

-x-y=1

x + y = -1

y = -x - 1

Equating the y values

-x - 1 = x+ 3

-x-x = 3 + 1

-2x = 4

x = 4/-2

x = -2

Substitute x = -2 into y = x+3

y = -2 + 3

y = 1

Hence the required coordinate is (-2, 1)
