PLEASE HELP ASAP!!
The diameter of each of the three circular lights in a traffic signal is 7 inches. In this activity, you will find the total area of the three lights.

Part A
Each circular light has a diameter of 7 inches. What is the radius of each light?

Answer:

14 marble

Step-by-step explanation:

here's your solution

=> Total number of marble = 35

=> ratio of David and Jason = 2 : 3

=> let the ratio be in x

=> now, 2x + 3x = 35

=> 5x = 35

=> x = 35/5

=> x = 7

=> number of marble with David = 7*2 = 14

=> number of marble with Jason = 7*3 = 21

hope it helps

Answer:

number of marbles that David had=

[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]

Answer:

[tex]b = l\times w[/tex] to guarantee that both formulas are the same.

Step-by-step explanation:

Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that [tex]l,w,h[/tex] have length units, whereas [tex]b[/tex] have area unit, that is, the square of length.

Hence, [tex]b = l\times w[/tex] to guarantee that both formulas are the same.

Answer: 240 birds are blue

Step-by-step explanation:

Takes 35 x 2=70 so 20 x 35 is 700 then do 12 x 20 and your answer is 240

Answer: 17/21

Step-by-step explanation:

Number of cities = 42

Fraction of cities that has lake = 5/42

Fraction of cities that have rivers = 29/42

The fraction of these 42 cities that have a lake or river running through them will then be:

= 5/42 + 29/42

= 34/42

= 17/21

Answer: Simplifying

4x + 50 = 6x + 20

Reorder the terms:

50 + 4x = 6x + 20

Reorder the terms:

50 + 4x = 20 + 6x

Solving

50 + 4x = 20 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

50 + 4x + -6x = 20 + 6x + -6x

Combine like terms: 4x + -6x = -2x

50 + -2x = 20 + 6x + -6x

Combine like terms: 6x + -6x = 0

50 + -2x = 20 + 0

50 + -2x = 20

Add '-50' to each side of the equation.

50 + -50 + -2x = 20 + -50

Combine like terms: 50 + -50 = 0

0 + -2x = 20 + -50

-2x = 20 + -50

Combine like terms: 20 + -50 = -30

-2x = -30

Divide each side by '-2'.

x = 15

Simplifying

x = 15

Answer:

y = 2x + 4

Step-by-step explanation:

Figure out the slope.

y2 - y1 / x2 - x1       8 - 6/ 2 - 1 = 2

Find out the y-intercept. Your equation so far is y = 2x + b.

8 = 2(2) + b

8 = 4 + b

4 = b

Answer:

55°

Step-by-step explanation:

∠KJL=180° - 125 = 55°

KL=KJ

so, ∠KJL= ∠KLJ =55°

Answer:

Acute triangle

Step-by-step explanation:

All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.

If any one of the three angles is 90, then it is right triangle.

If any one of the three angle is more than 90, then it is obtuse triangle.

Answer:

square root of (1-5)²+(-12+8)²

square root of (16+16)

square root of 32

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.

Answer:

You need to rent

14

videos, and you'll pay the same amount for both. Renting

15

will make the membership a better method of payment.

Explanation:

We can create an equation. Say the number of videos you rent is given by

n

. We can write that, if we rent

n

videos without membership, we'll have to pay

4

n

. If we rent the same amount of videos with membership, we'll have to pay

21

+

2.5

n

.

To find the value of

n

such that the amount you pay without membership is equal to the amount you pay with, we write:

4

n

=

21

+

2.5

n

1.5

n

=

21

n

=

1.5

n

Answer:

4

Step-by-step explanation:

okay since there was a 50% INCREASE, 6 is (100%+50%) greater than last months amount.

100%+50%=150%=1.5

let's say that x is last months amount

6=1.5x

x=6/1.5

x=4

There were 4 musicians in the band last month.

Answer:

1/2 or .5

Step-by-step explanation:

Hey There!

So the first step of this problem is to get y on one side and everything else on the other side

to do so we use inverse operations

so to get rid of the 2x we subtract 2x from each side

we would end up with -4y=5-2x

now want to get rid of the -4 on the y

to do so we would divide each side by -4

we would end up with

[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]

so we can conclude that the slope is 1/2 or .5
