Answer:

Subtraction property of equality (a)

The answer is A because the subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.

Answer:

h= 2v / πr²

Step-by-step explanation:

height of a cone is twice of it's volume divided by π and square of radius

Step-by-step explanation:

v = 1/2 πr²h

v / 1/2 πr² = 1/2 πr²h / 1/2 πr² (Divide both sides of the equation by 1/2 πr² to find the formula for height (h).

v / 1/2 πr² = h or h = 2v / πr²

Answer:

95⁰

Step-by-step explanation:

next time you want to figure this out, here's how

- they are supplementary angles, so you just subtract 45⁰ from 180⁰

180-45=95

so, you would get the answer 95⁰

for next time, you might not have as much information as you do in this equation so be careful

hope this helps!

Answer:

70

Step-by-step explanation:

Since this is supplementary, these two angles add up to 180 degrees. Therefore:

180 - 45 = 135

135 = 2x - 5

140 = 2x

x = 70

Each loft was $0.70 cents?

Step-by-step explanation:

$16.59/ 21 =$0.70

I just read the including tax part. How much was the tax?

Answer:

$.84

Step-by-step explanation:

16.59 * .06 = .9954

.9954 + 16.59 = 17.5854

17.5854 / 21 = .8374

.8374 rounded to the nearest hundredth is .84

Answer:

they should meet at point (1, 1)

Answer:

Step-by-step explanation:

The equation takes the form (x - h)² + (y - k)² = r², where  h is the x coordinate, k is the y coordinate of the center and r is the radius of the circle.

The center of circle is the middle of diameter.

The radius is the distance between the center and any point from the circumference of a circle.

The middle of diameter:

[tex]\left(\frac{18+4}2\,;\,\frac{-13-3}2\right)=\left(\frac{22}2\,;\,\frac{-16}2\right)= \left(11\,;-8\right)[/tex]   ⇒ h = 11, k = -8

The distance between the center and point (4,-3)

[tex]r=\sqrt{(11-4)^2+(-8-(-3))^2}=\sqrt{7^2+(-5)^2}=\sqrt{49+25}=\sqrt{74}[/tex]

so the equation:

(x - 11)² + (y - (-8))² = (√74)²

(x - 11)² + (y + 8)² = 74

Answer:

Step-by-step explanation:

Looking at the first graph, we see that if x increases from 0 to 1, y decreases from 2 to 0:

m = rise / run = -2/1 = -2

Arbitrarily choose the reference point (1, 0).  

Then y = mx + b becomes 0 = -2(1) + b, where b is the y-intercept.

Then b = 2, and the desired equation is

y = -2x + 2  

Answer:

15. slope=-2

y-intercept=2

16. slope=2

y-intercept=1

Answer:

Step-by-step explanation:

Chloe = 18inches of red licorice.

Reid = 6inches of red licorice

Total = 18 inches + 6 inches

= 24 inches

what fraction of a yard of red licorice do Chloe and Reid have together

Chloe and Reid have 24 inches altogether

1 yard = 36 inches

Fraction = 24 inches / 36 inches

= 2/3

Answer: 108 liters of gasoline is needed.

Hope this helps! :)

Given parameters:

Distance  = 140km

 Volume of gasoline  = 35liters

Unknown:

Volume of gasoline needed for 432km  = ?

Solution:

Let us first find the rate of gasoline consumption per mile. Using this value, we can then determine the volume of gasoline used for the distance given.

  Rate of gasoline consumption by the boat = [tex]\frac{volume of gasoline}{distance}[/tex]

                                                    = [tex]\frac{35}{140}[/tex]  

                                                    = 0.25liters/km

Now, the volume of gasoline needed for 432km;

   Volume of gasoline needed  = rate of gasoline consumption x distance

                                                    = 0.25 x 432

                                                    = 108liters of gasoline

Hi there !

x + 13 + x + 23 = 90

2x = 90 - (13+23)

2x = 90 - 36

2x = 54

x = 54 : 2

x = 27°

Good luck !

Answer: 5x*10

Step-by-step explanation:

Answer:it's 5x*10 other guys right

Step-by-step explanation:

Answer:

D. 1, 5, 7, 9, 11, 14, 16

Step-by-step explanation:

The following angles has the same measure as <3 = 20°:

m<7 = m<3 (corresponding angles are congruent)

m<5 = m<3 (alternate interior angles are congruent)

m<1 = m<3 (vertical angles are congruent)

m<14 = m<3 (corresponding angles are congruent)

m<16 = m<3 (alternate exterior angles are congruent)

m<9 = m<14 = m<3 (corresponding angles are congruent)

m<11 = m<9 = m<3 (vertical angles theorem and corresponding angles theorem)

Therefore, angles labelled D. 1, 5, 7, 9, 11, 14, and 16 all have the measure of 20°.

Answer:

the slope should be 4/2

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Slope (m) =  

ΔY

ΔX

=  

4

1

= 4

θ =  

arctan( ΔY )

ΔX

= 75.963756532074°

ΔX = 4 – 2 = 2

ΔY = 16 – 8 = 8

Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353
