Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, wh

Elanso [62]

Answer:

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

Step-by-step explanation:

we know that

The dimensions of the garden in the actual are 10 ft by 5 ft

The dimensions of the garden on the scale drawing are 12 in. by 6 in

step 1

Find the scale factor

To find the scale factor divide the corresponding side on the scale drawing by the corresponding side in the actual

$\frac{12}{10}\ \frac{in}{ft}$

simplify

$1.2\ \frac{in}{ft}$

That means

1.2 inches in the drawing represent 1 foot in the actual

step 2

Find out the dimensions of the herb garden on the scale drawing

we know that

The dimensions of the herb garden in the actual are 2 ft by 5 ft

Multiply by the scale factor

$2\ ft=2(1.2)=2.4\ in$

$5\ ft=5(1.2)=6\ in$

therefore

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

Trina rolled a number cube three times determine the probability of rolling and even number on each roll

1/2 x 1/2 x 1/2 = 0.125

Assuming the dice is six-sided, we know that there are three even numbers. 3/6 can be simplified to 1/2. Since you want to get an even number three times, and you are using the same dice, you must multiple 1/2 by itself three times.

Geri ran in a marathon race. It took her 3 hours and 28 minutes to run 26 miles. How many minutes did it take her to run 1 mile

ankoles [38]

Answer:

8/mile = 8

Step-by-step explanation:

convert hours to minutes. 3 hours, 28 minutes converted to minutes is...

3*60 (60 minutes in an hour)

=180

180+28 (don't forget to add what was already converted to minutes!)

=208

208/26 (divide time by distance ran)

=8 (8 minutes per mile)
