The area of a rectangle is 25/42 and its width is 5/6. What is the length? ASAP
Serhud [2]

Answer:

<h2>length =  \frac{25}{28}</h2>

Step-by-step explanation:

Let the length of the rectangle be l

Area of a rectangle = length × width

From the question

Area = 25/42

width = 5/6

Substitute the values into the above formula and solve for the length

That's

<h3>length =  \frac{area}{width}</h3>

So we have

<h3>length =  \frac{25}{42}  \div  \frac{4}{6}  \\  =  \frac{25}{42}  \times  \frac{6}{4}  \\  =  \frac{25}{7}  \times  \frac{1}{4}</h3>

We have the final answer as

<h3>\frac{25}{28}</h3>

Hope this helps you

What is the surface are of a rectangular prism of the length is 18cm the width 6cm and the height 3cm
Harlamova29_29 [7]

The surface area of rectangular prism is 360 square inches

<em><u>Solution:</u></em>

Given that rectangular prism of the length is 18 cm the width 6 cm and the height 3 cm

To find: Surface area of rectangular prism

<em><u>The Surface area of rectangular prism is given by formula:</u></em>

A=2(wl+hl+hw)

Where,

"l" is the length and "h" is the height and "w" is the width of prism

From given,

l = 18 cm

w = 6 cm

h = 3 cm

<em><u>Substituting the values in formula,</u></em>

A = 2((6 \times 18) + (3 \times 18) + (3 \times 6))\\\\A = 2(108+54+18)\\\\A = 2 \times 180\\\\A = 360

Thus surface area of rectangular prism is 360 square inches

Is the following relation a function? <br><br><br> Need answer now
pishuonlain [190]
<h3>Answer: No, it is not a function</h3>

If you can draw a vertical line through more than one point on the curve, then it's not a function. In this case, we can draw such a line. The graph is said to have failed the vertical line test.

What this means is that some x inputs lead to more than one y outputs. A function is only possible if any x input leads to exactly one y output. The x input must be in the domain.

What is the radius of a hemisphere with a volume of 165\text{ cm}^3,165 cm 3 , to the nearest tenth of a centimeter?
DanielleElmas [232]

Answer:

4.3cm

Step-by-step explanation:

the radius of the hemisphere can be determined its volume

volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

(2/3) x (22/7) x( r^3) = 165 cm^3

44/21 x r^3 = 165

divide both sides of the equation by 21/44

165 x 21/44

r^3 = 78.75

find the cube root

r = 4.2863 cm

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

the 100th terms, 8 is greater than 6, so add 1 to 2. this give 4.3cm
