V Find the value of x in the triangle. 55° 629 c. 63​

Answer:

28cm

Step-by-step explanation:

7x4

or

7+7+7+7

Answer:

(-7,-3)

Step-by-step explanation:

You keep the -3 since that is the y but the x will become negative because you are reflecting to the left and not the right, making the x then negative.

Answer: (-7,-3)

Step-by-step explanation:

The point (7,-3) is located in the fourth quadrant  mean that if you reflect the point across the  y a-xis, it should end up in the third quadrant.

If you flip a point over the y axis, the x coordinate switches.

(7,-3) ⇒ (-7,-3)

Hi, did you forget to attach the two-way table to the question? I can't seem to see it, so I can't answer your question

Step-by-step explanation:

the answer is explained above

Answer:

x=8

Step-by-step explanation:

You would set them equal to each other to get 9x-13=6x+11.

You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.

Then move the -13 over so add 13 to both sides to get 3x=24

Then get x by itself so divide by 3 to get x=24/3.

Then that simplified is 8

Answer: Mary Jane got 51 questions correct.

Step-by-step explanation: x/60 and 85/100. Multiply 60 and 85. When you get your answer, divide it by 100. It should give you the answer.

Answer:

[tex]9\pi \: \mathrm{ft^2\:or}\: 28.27 \mathrm{\: ft^2}[/tex]

Step-by-step explanation:

The area of a circle is given by [tex]r^2\pi[/tex] where [tex]r[/tex] is the radius of the circle. The diameter is given as [tex]6[/tex] feet, so the radius of this circle is [tex]\frac{6}{2}=3[/tex] feet.

Plugging in our values, we get:

[tex]3^2\pi=9\pi\approx28.27[/tex].

If there are 80 marbles, and Raquel has collected 3/8 of them, he has collected 30

Answer:

below

Step-by-step explanation:

Geometric series with first term 3 and common ratio r.

Last variety = 3 * 2^(12-1) = 6144.

Total =  3 * (2^12 - 1) / (2-1)

= 12285

Answer:

C

Step-by-step explanation:

Step-by-step explanation:

3√(x - 4) + 7 = -14

3√(x - 4) = -21 (subtract 7 from both sides)

√(x - 4) = -7 (divide 3 on both sides)

However √y is non-negative for all values of y in the domain of √y.

Hence there is no real solution for x.

Answer:

a≤9

Step-by-step explanation:

Answer:

a ≤ 9

Step-by-step explanation:

2a-5 ≤ 13

add +5 then divide both sides by 2 to isolate the variable

step 1: 2a-5+5 ≤ 13+5 → 2a ≤ 18

step 2: 2a/2 ≤ 18/2 → a ≤ 9

Answer:

Trevor is just under halfway through his homework

Step-by-step explanation:

The following information is given in the question

Trevor has completed 5 of his 12 homework problems

So here the total number of homework is 12

And, out of them trevor has completed 5

So if we do the half of 12 than it would come 6

This means that trevor just under halfway the homeowrk

Therefore the last option is correct

The answer is

x ≤ -3  

Step-by-step explanation:

Distance traveled in 10 hours = 5,000 miles

Distance travelled in 3 hours = 5,000 * (3/10)

= 1,500 miles.

Hence the airplane travelled 1,500 miles in 3 hours.

Step-by-step explanation:

Assuming it traveled at a constant speed, you can set up a proportion

[tex] \frac{5000}{10} = \frac{x}{3} [/tex]

X = (3*5000)/10

X = 1500 miles

each day is 24 hours.

so minus 11 from 24 , 5 times, since theyre 7 days in a week.

Answer:

1/19

Step-by-step explanation:

y = number of yellow cubes

3y = number of blue cubes

5(3y) = number of green cubes

total number of cubes = 19

P(yellow) = 1/19

Answer:

1 1/2

Step-by-step explanation:

set up a proportion:

8 = 12

1        x

cross-multiply:  8x = 12

                          x = 12/8

                          x = 3/2 (simplified)

Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.

Step-by-step explanation:

360/2 = 180

therfore it has 180 sides

Answer:

y=-4+5x

Step-by-step explanation:

To get y by itself you need to move the -10x to the other side, to do that you need to add 10x on both sides

2y-10x+10x=-8+10x

Simplify and you will get 2y=-8+10x

Now divide everything by 2

2y/2=-8/2+10x/2

Simplify and you will get y=-4+5x

Answer:

I(20) is 600 dollars

Step-by-step explanation:

From the given function, I(p) = p(50 - p)

Where I is the income in dollars and p is price dollars.

To determine I(20), that is, to determine the income in dollars when the ticket price is 20 dollars.

From

I(p) = p(50 - p)

When p = 20

Then,

I(20) = 20(50 - 20)

I(20) = 20(30)

I(20) = 20 × 30

I(20) = 600

Hence, I(20) is 600 dollars

That is, the income is 600 dollars when the ticket price is 20 dollars.
