Answer:

I'll find X for you; the next step is by you.

Step-by-step explanation:

we have two similar pentagons

I will do it in 2 ways.

1.

=> 48/4x = (x+2)/x

=> 12/x = (x+2)/x

Because of pentagons so x > 0

=> 12 = x + 2 => x = 10

2.

k is unknown number

=> 4x = k.x and 48 = k.(x + 2) (x > 0)

=> k = 4 and 48 = 4.(x + 2)

=> 12 = x + 2 => x = 10

Forty-five percent of the 300 shoppers in a supermarket bought milk. How many of the shoppers in a supermarket bought milk?
Orlov [11]
Turn 45% into a decimal.  You get 0.45,  because you move the decimal two places to the left.

Then multiply 300*0.45
You get 135

135 Shoppers in the supermarket bought milk.

Which equation can be used to represent six added to twice the sum of a numbee and four is equal to one half of the difference o
Ronch [10]

Answer:  6 + 2 (x+4) =   \frac{3}{2}(3-x)

Step-by-step explanation:

let the number be x , then :

six added to twice the sum of a number and four means :

6 + 2 (x+4)

one half of the difference of three and the number means :

\frac{3}{2}(3-x)

combining the two , we have

6 + 2 (x+4) = \frac{3}{2}(3-x)

arsen [322]

Answer:

It will take 10 hours.

Step-by-step explanation:

By using the formula of motion,

v = u + at

Here, v = Final speed of an object

u = initial speed

a = Acceleration by which the speed is increasing

t = Duration or time

Now substitute the values given in the question,

80 = 50 + 3t

3t = 30

t = 10 hours

Therefore, after 10 hours speed of the bus will be 80 mph.

Jermaine has just painted a large mural. It is 8 1/2 feet wide. The wall he wants to place it on is 11 3/4 feet wide. About how
PolarNik [594]
First turn 1/2 to 2/4 so you have a common denominator.
Next turn the mixed numbers into improper fractions:
11 3/4 --> 47/4 and 8 2/4 --> 34/4
Subtract:
47/4 - 34/4 = 13/4
Divide:
13/4 = 3.25
3.25/2 --> 1.625 or 1 5/8
Therefore, he will have to place it 1 5/8 feet from each side

Hope this helps!
