Answer:

Option D. 11.148 sq. meters

Step-by-step explanation:

Area of an office is given as 120 square ft. and we have to convert the measurement in square meters.

Since 1 feet = 0.3048 meter

and 1 square feet = (0.3048)² meter²

1 square feet = 0.093 met²

Therefore 120 sq. feet = 120×0.093 = 11.148 sq. meters.

Answer is option D. 11.148 sq meters.

Part B. Mr. Jefferson could ride 3 miles in 12 minutes

Step-by-step explanation:

Part A. 4 being the time it takes him to travel 1 mile and x being the number of miles rode.

Part B. To find the time it took him to travel each mile I divided 20 by 5 which gave me four. Then to find the miles he could ride in 12 minutes I divided 12 from 4 which gave me three, stating that he could travel 3 miles in 12 minutes.

Simplify the expression so there’s only one positive power for the base, -5.

Yuri [45]

Given:

The expression is

$(-5)^7\div (-5)^2$

To find:

The simplified form of the given expression so there is only one positive power for the baser -5.

Solution:

We have,

$(-5)^7\div (-5)^2$

$=\dfrac{(-5)^7}{(-5)^2}$

Using the properties of exponents, the given expression can be written as

$=(-5)^{7-2}$ $[\because \dfrac{a^m}{a^n}=a^{m-n}]$

$=(-5)^{5}$

Here, the base is -5 and the exponent is 5.

Therefore, the correct option is C.

A = 360 cm^2

Step-by-step explanation:

Using Pythagorean theorem, the length AB is given by

AB^2 = 17^2 - 8^2 = 225 cm^2

AB = 15 cm

Since the ratio BC: CD = 1:2 and BC = 8 cm, this means that CD = 2×(8 cm) = 16 cm

so the length BD is

BD = BC + CD = 8cm + 16 cm = 24 cm

There the area of the rectangle is

A = AB×BD

= 15cm×24cm

= 360 cm^2
