solniwko [45]

Answer:

The area of the actual wall is 693 square feet.

Step-by-step explanation:

Step 1 : Finding the length of the wall in feet.

Length of the wall in the scale drawing = 28 inches

Length of the actual wall = $28 \times \frac{3}{2}$ feet

Length of the actual wall = $\frac{84}{2}$ feet

Length of the actual wall = 42 feet

Step 2 : Finding the width of the wall in feet.

Width of the wall in the scale drawing = 11 inches

Width of the actual wall = $11 \times \frac{3}{2}$ feet

Width of the actual wall = $\frac{33}{2}$ feet

Width of the actual wall = 16.5 feet

Step 3 :

Find area of the wall in square feet.

Area of the actual wall = Length x Width

Area of the actual wall = 42 x 16.5

Area of the actual wall = 693 square feet.

Greg’s house is 0.8 miles from the library. So far, Greg has walked 5/6 of the distance. How many miles has he walked in fractio

Anastaziya [24]

Greg has walked $\frac{2}{3}$ miles

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

Given that, Greg’s house is 0.8 miles from the library

Distance between house and library = 0.8 miles

Greg has walked $\frac{5}{6}$ of the distance

Therefore,

Distance walked = $\frac{5}{6}$ of the distance between house and library

Here "of" means multiplication

Thus we get,

$\text{Distance walked } = \frac{5}{6} \text{ of } 0.8$

$\rightarrow \frac{5}{6} \times 0.8 = \frac{5}{6} \times \frac{8}{10}\\\\\text{Simplify the above fraction by reducing to lowest terms }\\\\\rightarrow \frac{5}{6} \times \frac{8}{10}=\frac{2}{3}$

Thus Greg has walked $\frac{2}{3}$ miles

Using the following data, calculate the mean absolute deviation:

Len [333]

Answer:

The mean absolute deviation of the data set is 2.4

Step-by-step explanation:

To determine the mean absolute deviation (MAD) of the data, we start by finding the mean of the data set.

The mean is obtained by finding the sum of the data values, and then dividing the sum by the number of data values.

Find the absolute value of the difference between each data value and the mean: |data value – mean|.

Find the sum of the absolute values of the differences.

Divide the sum of the absolute values of the differences by the number of data values.

Chase scored 11 points on monday, and he doubled his score each day thereafter. how many points did he score on friday? 176 poin

Levart [38]

Jacob adds a factor of 2 with each passing day. We have

$11 = 11 \cdot 2^0$ on Monday

$22 = 11 \cdot 2^1$ on Tuesday

$44 = 11 \cdot 2^2$ on Wednesday

$88= 11 \cdot 2^3$ on Thursday

$176= 11 \cdot 2^4$ on Friday
