Are these parallel, perpendicular, or neither?

Answer:

x = 7

Step-by-step explanation:

From the above question, we are told that:

∠A and ∠B vertical angles.

It is important to note that vertical angles are equal to each other

Hence:

∠A = ∠B

From the question,

∠A = (5x−2)°

∠B = (3x+12)°

Hence:

(5x−2)°= (3x+12)°

5x - 2 = 3x + 12

Collect like terms

5x - 3x = 12 +2

2x = 14

x = 14/2

x = 7

Answer:

X=14

Answer:

[tex]3(-2m + 3)[/tex]

Step-by-step explanation:

Given

[tex]-6m + 9[/tex]

Required

Factorize

Expression: [tex]-6m + 9[/tex]

Start by expressing the expression as a sum of products.

[tex]-6m = 3 * -2m[/tex] and

[tex]9 = 3 * 3[/tex]

So;

[tex]3 * -2m + 3 * 3[/tex]

Notice that constant 3 is common in both terms.

This can then be factorizes as:

[tex]3(-2m + 3)[/tex]

Hence:

[tex]-6m + 9 = 3(-2m + 3)[/tex]

Answer:

3(-2m+3)

0t−15−7.5t=6−0.5t

2 Simplify  10t-15-7.5t10t−15−7.5t  to  2.5t-152.5t−15.

2.5t-15=6-0.5t2.5t−15=6−0.5t

3 Add 1515 to both sides.

2.5t=6-0.5t+152.5t=6−0.5t+15

4 Simplify  6-0.5t+156−0.5t+15  to  -0.5t+21−0.5t+21.

2.5t=-0.5t+212.5t=−0.5t+21

5 Add 0.5t0.5t to both sides.

2.5t+0.5t=212.5t+0.5t=21

6 Simplify  2.5t+0.5t2.5t+0.5t  to  3t3t.

Answer:

k = 0.25t^2

Step-by-step explanation:

Given the equation :

b = 0.25t

b = number of inches that has burned away

t = time

From our knowledge of variation;

Since candle length will decrease with time ;

b α 1/ t

b = k/t

Where k is the proportionality constant

Comparing the equation :

b = 0.25t

k/t = 0.25t

k = 0.25t^2

Step-by-step explanation:

An equilateral polygon has congruent sides, like a rhombus.

An equiangular polygon has congruent interior angles, like a rectangle.

In other words: Equilateral doesn't necessarily have congruent INTERIOR angles while equiangular does have/need congruent interior angles.

THEY STOLE $50 FROM MY GRANDPA'S PAYPAL !!!

Answer:

89.10 / 4.95 is 18. so the first one is 18.

6 and 9, so we have to find the LCM. 6,12,18 and 9,18, so the first one to get a red and blue cap is the 18th bottle.

We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90  10,20,30,40,50,60,70,80,90.

The first one to get all three is  the 90th bottle.

Hope this helps plz hit the crown :D

Answer:

x = -1

Step-by-step explanation:

i multiplied the first equation by 2 to eliminate the fractions and got:

-4x + y = 3

used substitution method:  y = 3 + 4x

x - 3(3 + 4x) = 2

x - 9 -12x = 2

-11x = 11

x = -1

Answer:

I don't know what's I don't know I'm really sorry very very very very very very very very very very very very sorry very sorry

first you combine like terms

25m + 43,200 = 45,675 - 200m

then you add 200m to both sides

225m + 43,200 = 45,675

then you subtract 43,200 from both sides

225m = 2,475

then you divide both sides by 225

m = 11

Lateral Surface Area of a Cone

Given a right circular cone of base radius r and height h, the lateral surface area is given by:

[tex]A=\pi r\sqrt{r^2+h^2}[/tex]

We are given the lateral area of a funnel as A=236.64 square cm and the radius is r=4.75 cm. It's required to find the height of the cone. It can be calculated by solving for h.

Squaring:

[tex]A^2=\pi^2 r^2(r^2+h^2)[/tex]

Dividing by [tex]\pi r^2[/tex]

[tex]\displaystyle \frac{A^2}{\pi^2 r^2}=r^2+h^2[/tex]

Subtracting [tex]r^2[/tex]:

[tex]\displaystyle \frac{A^2}{\pi^2 r^2}-r^2=h^2[/tex]

Taking square root:

[tex]\displaystyle h=\sqrt{ \frac{A^2}{\pi^2 r^2}-r^2}[/tex]

Substituting the values:

[tex]\displaystyle h=\sqrt{ 251.472-22.5625}[/tex]

[tex]\displaystyle h=\sqrt{ 228.909}[/tex]

h = 15.13 cm

Answer:

the computer will cost 864.5

Step-by-step explanation:

15% of 950 is 142.5.

950-142.5=807.5

6% of 950 is 57

Answer:

$855.95

Step-by-step explanation:

So We can first multiply the original price by 0.85 becuase its 15 percent off and we’re paying 85 percent of the original price basically.

You’ll get 807.50.

Now to find the sales tax we multiply that by 1.06 becuase the 100 percent is the price now and we’re just adding 6 percent so 1.06, and you’ll get 855.95

So no adding and subtracting and that takes off 2 steps and its way quicker

So the final answer is $855.95

Answer:

91.6 km/h

Step-by-step explanation:

Let v = average speed of van = 65 km/h and v' = average speed of car. Let t be the time the car starts to move. The van started 35 minutes earlier at t' = (t + 35/60) h.

Since distance d = vt where v = velocity and t = time, the distance moved by the van d = vt' = v(t + 35/60) and that moved by the car is d' = v't.

Since the car catches up with the van after it had moved a distance of 130 km,  d = d' = 130 km.

So d = v(t + 0.583)

Substituting d = 130 km and v = 65 km/h, we have

130 km = 65 km/h(t + 0.583)

130 km = (65t + 37.895 )km

subtracting 37.895 from both sides, we have

130 km - 37.895 km = 65t

92.105 = 65t

dividing both sides by 65, we have

t = 92.105/65

= 1.417 h

≅ 1.42 h

Since d = d' = v't,

v' = d'/t

= 130 km/1.42 h

= 91.55 km/h

≅ 91.6 km/h

So, the average speed of the car is 91.6 km/h
