This shape consists of:
1- A 4 triangles with dimensions of ( 6.5 & 3 inches) 
2- A square with  dimensions of ( 6.5 x 6.5 inches) 

The total Area= Area of 4 triangles + Area of the square 
= 4 *(6.5 * 3) + (6.5 *6.5) 
= 120.25 inches²

What is the ratio of 364:78
Klio2033 [76]
You'd want to simplify that by dividing both terms by the greatest common factor which is the product of the shared primes of both numbers prime factorization...

364=2*2*7*13, 78=2*3*13, so the GCF is 2*13=26, now divide both terms by 26

A machine covers 5/8 square foot in 1/4 hour. what is the unit rate?
Ilia_Sergeevich [38]

we know that

<u>Unit Rate</u> is the ratio of two measurements in which the second term is one

so

to find the unit rate divide (5/8) by (1/4)

Unit\ rate=\frac{(5/8)}{(1/4)}= \frac{5}{8}*4= \frac{2.5}{1} =2.5 \frac{ft^{2}}{hour}

therefore

<u>the answer is</u>

The unit rate is 2.5 \frac{ft^{2}}{hour}

For each formula,rearrange so a is by itself:
vichka [17]

Step-by-step explanation:

a) 6-9b=3a

First:Subtract

3b=3a

Second: Devide

3b/3a

=(3÷3)(b÷a)

=1b/a

= b/a

B) 6b+2a=3a

First:Transpose (Group the like terms. signs will change.)

-3a+2a=-6b

=-1a=-6b

Second:Divide

=-1a/-6b:(-1÷-6)(a÷b)

=1a/6b

=a/6b

C)a/3=b+2

First: Transpose

a=3+2+b

=a/6+b

Find the value of x and m∠HKL.
frosja888 [35]

Answer:

x = 25 degrees   ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25
