(6a + 6) + (3x - 2) + (2a + 4)

Answer:

a. About 263.08 m²

Step-by-step explanation:

First find the radius (r):

Area of sector = central angle/360 ×πr²

Area of sector = 85.5 m²

Central angle = 117°

Plug in the values into the equation

85.5 = 117/360 × π*r²

85.5 = 1.02 × r²

85.5 - 1.02 = r²

84.48 = r²

r = √84.48

r = 9.19 m

✔️Find the area of the circle

Area of the circle = πr²

Where,

r = 9.19

Plug in the value

Area = π*9.2²

Area = 265.326663 (this is close to 263.08 cm²)

Area therefore is about 263.08 cm².

Answer:

4000 miles

Step-by-step explanation:

320x1.5=480

(320x5)+(480x5)=4000

4000 miles

Answer:

[tex]4,000\text{ miles}[/tex]

Step-by-step explanation:

Let's say that the two planes travel at point [tex]p[/tex]. Without loss of generality, let's say that the first plane travels left and the second plane travels right.

Distance is given by [tex]d=rt[/tex], where [tex]r[/tex] is rate or speed and [tex]t[/tex] is time.

If the first plane travels at a speed of 320 mph and the second plane travels 1.5 times this, the second plane must travel [tex]320\cdot 1.5=480[/tex] mph.

Using [tex]d=rt[/tex], the first plane must travel:

[tex]d=320\cdot 5=1600[/tex] miles

The second plane must travel:

[tex]d=480 \cdot 5=2400[/tex] miles

However, these are the planes' respective distances from point [tex]p[/tex]. Since they travelled in opposite directions, the total distance between them is equal to [tex]1600+2400=\boxed{4,000\text{ miles}}[/tex]

Answer:

The probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 24.50%.

Step-by-step explanation:

Given that out of 449 applicants for a job, 253 have over 5 years of experience and 62 have over 5 years of experience and have a graduate degree, to determine what is the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, the following calculation must be performed:

253 = 100

62 = X

62 x 100/253 = X

6,200 / 253 = X

24.50 = X

Therefore, the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 24.50%.

Answer:

not sure man... goodluck tho

Answer:

Step-by-step explanation:

diameter=12 cm

radius r=12/2=6 cm

area A=πr²=3(6)²=108 cm²

Answer:

YOUR ANSWER IS B

Step-by-step explanation:

if RD is 12cm so AR is 12cm too... since the R is placed in the middle and we can analyze too that the AD is 24cm since RD is 12cm and AR is 12cm so...

12+12=24

AR= 12cm

Answer:

y=12, x=6

Step-by-step explanation:

y+3=15

3x-6=12

y=3x+6

Use

y=mx+b

to calculate the equation of the line, where

m

represents the slope and

b

represents the y-intercept.

Slope is equal to the change in

y

over the change in

x

, or rise over run.

Answer:

The graph below shows the answer to

2x - 3y < 12

Also shown as

-3y < -2x + 12

Step-by-step explanation:

You can rearrange the inequality by subtracting 2x from both sides to isolate the y.

You now have -3y < 12 -2x

which can be put into the standard linear equation form of

-3y < -2x + 12

Then you divide both sides by -3 to get singular value of y, which is something like

-3/-3y < -2/-3x + 12/-3

which is

y > 2/3x -4

Note: I switched direction of the inequality because you are dividing both sides by a negative value.

Hey there!

Since the given equation is subtracting, we're going to do the opposite of s traction which addition; whereas addition opposite is subtraction, division is multiplication, and multiplication is division. Now that we got that information out the way, we can finally answer your question

The very first step to solving c - 7 = 13 is ADDING 7 to BOTH SIDES because it is the opposite of subtracting

Answer you're looking for: Option A. Add 7 to both sides of the equation

Good luck on your assignment and enjoy your day!

~Amphitrite1040:)

Answer:

Step-by-step explanation:

First you need to put the equation in slope intercept form.

y = mx + b   (m = slope and b = y-intercept)

5x + 2y = 12   (subtract 5x)

2y = -5x + 12   (now you need to isolate y. Therefore, divide all by 2)

y = -5/2x + 6

Now you have your slope and y-intercept. Your y-intercept will be 6. So on the graph you need to begin at 6 on the y-axis (the line that goes up and down). Make your first point there. Your slope is the -5/2x. Slope is looked at as rise/run. This means from your point at 6, you will go down (down because it's negative. If it was a positive, you would go up, i.e rise) 5 units. Then you will go over to the right 2 units (to the right because it is positive. Only the top one will be negative.) Place your point once you have done that. Then draw a line between those two points.

(note that on my screenshot, the tiny squares do not equal 1 unit. The larger ones with the bunch of tiny squares inside equal 1 unit)

I hope this helped :)

Answer:

B

Step-by-step explanation:

This one takes a little trial and error but you can probably find the answer quickly.

Answer:

x = 15

Step-by-step explanation:

Create a proportional relationship to solve for x

3/2 = x/10

Cross multiply

2x = 30

Divide both sides by 2

x = 15

Answer:

Step-by-step explanation:

10/(10 + 2) = x/(x + 3)      Combine left denominator

10/12 = x/(x + 3)              Cross multiply  

10(x + 3) = 12*x                Remove the brackets on the left

10x + 30 = 12x                Subtract 10x from both sides

-10x           -10x

         30 = 2x                Divide by 2

2x/2 = 30/2

x = 15

Step-by-step explanation:

<5 is congruent to <3 ( parallel lines form alternate interior angles)

the sum of angles 1,2,3 equal 180 as well

Answer:

[tex]3 \to[/tex] Coefficient of x

[tex](x+2)\to[/tex] Variable

[tex]4 \to[/tex] Constant

Step-by-step explanation:

Given

[tex]3x + 2(x +2) + 4[/tex]

Required

Complete the statements

In 3x, x is the variable; so:

[tex]3 \to[/tex] Coefficient of x

In 2(x + 2), 2 is the variable so:

[tex](x+2)\to[/tex] Variable

4 stands alone. So, it is a constant

[tex]4 \to[/tex] Constant

Answer: In the first term, 3 is a coefficient

In the second term, (x + 2) is a factor

In the last term, 4 is a constant

Step-by-step explanation:

The 3 in the first term is multiplied by a variable, x. So it is a coefficient.

The (x + 2) in the second term is multiplied by 2. So, it is a factor.

The 4 in the last term is not multiplied by anything. It is a fixed value, so it is a constant.
