Answer:
47 miles per hour
Step-by-step explanation:
so you have to do distance/time and divide the numbers.
so put 258.5 at the top because it's the distance then you put the time under it so 5.5 hour and divide that and you get 47 mph
Answer:each piece has 1/5 of 3 meters of fabric.
Step-by-step explanation:
Answer:
n = 3
Step-by-step explanation:
<u>Equation: 17.1 = 5.7 * n</u>
<em>Divide both sides by 5.7 to get n by itself.</em>
<u>Step 1: Divide both sides by 5.7</u>
17.1 = 5.7 * n
17.1 <u>/ 5.7</u> = 5.7 * n <u>/ 5.7</u>
divide divide
<em>3 = n</em>
Answer: n = 3
Answer:
132cm²
Step-by-step explanation:
You can find the area of the entire shape by calculating the area of seperate smaller shapes.
You can split them up into 2 rectangles, one with a base of 7cm and height of 4cm, and another one with a base of 7cm and height of 8cm. You also have 2 triangles, with a base of 19cm - 7cm / 2 = 6cm since it is the entire bottom line subtracted by the top; they will have a height of 8cm each.
To calculate the rectangles areas, simply do length x width, which are:
4cm x 7cm = 28cm²
8cm x 7cm = 56cm²
Next, since the triangles are similar in measurements, instead of doing the normal calculation to find the area of a triangle, you can do base times height again, which is:
6cm x 8cm = 48cm²
Add all the answers together to get the final area, which is 132cm².
