Answer:

<h3>The answer is 70cm</h3>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where

l is the length

w is the width

From the question

The length of a rectangle six times its width which is written as

l = 6w

Area = 150cm²

Substitute these values into the formula for finding the area

That's

150 = 6w²

Divide both sides by 6

w² = 25

Find the square root of both sides

width = 5cm

Substitute this value into l = 6w

That's

l = 6(5)

length = 30cm

So the perimeter of the rectangle is

2(30) + 2(5)

= 60 + 10

Hope this helps you

svet-max [94.6K]

Answer:

Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.

Step-by-step explanation:

Given

Minutes: 10 || 16 || ? || 48

-----Miles: 2.5 || 4 || 7.5 || 12

Required

Which statements solve for the missing value?

First, we need to calculate the ratio of minutes to mile

$Ratio = \frac{Minutes}{Mile}$

When minutes = 16; mile = 4

So, we have:

$Ratio = \frac{16}{4}$

$Ratio = 4$

Next, we multiply the ratio by 7.5

$Minutes = Ratio * 7.5$

$Minutes =4 * 7.5$

$Minutes = 30$

<em>Hence, option B answers the question.</em>

Write the standard form of the equation of the circle with radius 7 and center (5,−7).

olya-2409 [2.1K]

Answer:

$(x-5)^2+(y+7)^2=49$

Step-by-step explanation:

Use $(x-h)^2+(y-k)^2=r^2$ for the equation of a circle in standard form with radius $r$ and center $(h,k)$ . Therefore, the equation of the circle in standard form is $(x-5)^2+(y+7)^2=49$

Answer:

6.1 m

Step-by-step explanation:

Always draw a diagram! And now pythagorean theorem. a^2 + b^2 = c^2

Substitution:

a^2 + 2.8^2 = 6.7^2

a^2 + 7.84 = 44.89

a^2 = 37.05

a = 6.086...

Rounding <u>up</u> to one decimal point, thats 6.1 m
