Answer:

Option D is correct answer.

Step-by-step explanation:

For the area of Trapezoid we apply The formula

\frac{1}{2} sum of parallel  sides X distance between them

Here in the question we have area = 98 square units

parallel sides are 20 units and 8 units ,Plugging them in the above formula

Let d be the distance between them

98=\frac{1}{2} [ 8+20]  X d

98=14 X d

d= \frac{98}{14}

d = 7 units

Answer:

x = 7 units

Step-by-step explanation:

The area of the trapezoid is

A = 1/2 (b1+b2) *h

where b1 and b2 are the top and bottom and h is the height

Substituting what we know

 98 =1/2 (20 +8) *x

Combine like terms

98 = 1/2 (28)x

98 = 14x

Divide by 14 on each side

98/14 = 14x/14

7 =x

The difference of six times a number and seven results in 35.
Drupady [299]
Answer is A. add 7, and then divide by 6. Your equation would be 6x-7= 35, so first you add 7 to both sides. 6x=42, and then divide by 6. x= 7

Solve the equation 2p/3-12=-2
-BARSIC- [3]
Hey there! 

\frac{2p}{3} - 12 = -2

Firstly, we are going add 12 on each of the sides that we're working with. like ↓ 

p - 12 + 12 \\ \\ = -2 + 12

This gives us \frac{2}{3}p = 10 (if you are wondering how we got the out come of 10 it is because I added -2 + 12 = 10

Now multiply \frac{3}{2} on each of your sides 

\frac{3}{2} ( \frac{2}{3}p)  \\ \\  =  \frac{3}{2} (10)

Cancel the first set and you will find the value of p

p = 15

Good luck on your assignment and enjoy your day

3.95174 rounded to nearest hundredths
OlgaM077 [116]

The hundredths place is where the 5 is.

Look to the right of the hundredths place and determine if the number is 5 or more or if the number is 4 or less.

In this problem, the number to the right of 5 is 1, and 1 is less than 4.

This means you can keep the 5 the same and every number after the 5 becomes imaginary zeroes.

3.95174 becomes 3.95 (rounded to nearest hundredth).

What is the diameter of a sphere with volume of 7483
elena-14-01-66 [18.8K]

Answer:

The diameter of the sphere with the given volume is 24.268 units

Step-by-step explanation:

Volume of a sphere is given by the equation:

V=4/3\pi r^3

Plug in your volume and solve for r

7483=4/3\pi r^3

7483(3/4)=\pi r^3

5612.25=\pi r^3

5612.25/\pi =r^3

1786.43=r^3

\sqrt[3]{1786.43}=r

r = 12.134 units

d = 2r

d = 2(12.134)

d = 24.268 units
