evablogger [386]

Answer:

The total yards of cloth needed for the flags = 28

Step-by-step explanation:

Given:

Jake and his dad are making (6,12,18) different types of flags.

Each flag takes $(\frac{2}{3},\frac{3}{4},\frac{5}{6})$ of a yard of cloth.

To find the total yards of cloth needed in all.

Solution:

Flag A :

Each flag requires = $\frac{2}{3}$ of a yard of cloth

Total number of this flag = 6

Total cloth required for this flag = $\frac{2}{3}\times 6 = 4\ yd$

Flag B:

Each flag requires = $\frac{3}{4}$ of a yard of cloth

Total number of this flag = 12

Total cloth required for this flag = $\frac{3}{4}\times 12 = 9\ yd$

Flag C:

Each flag requires = $\frac{5}{6}$ of a yard of cloth

Total number of this flag = 18

Total cloth required for this flag = $\frac{5}{6}\times 18 = 15\ yd$

Thus, total yards of cloth needed for the flags = $4\ yd+9\ yd+15\ yd =28\ yd$

Three months later, Pepe averaged a speed of 4/5 of a mile in 1/10 of an hour, while Paula averaged 5/6 of a mile in 1/12 of an

MAVERICK [17]

Answer:

2 miles per hour

Step-by-step explanation:

We have to calculate the miles per hour of each person

Formula = Distance in miles/ Time in hours

a) For Pepe

Pepe averaged a speed of 4/5 of a mile in 1/10 of an hour

Hence,

= 4/5 miles / 1/10 hour

= 4/5 miles ÷ 1/10 hour

= 4/5 miles × 10/1 hour

= 8 miles per hour

b) For Paula

Paula averaged 5/6 of a mile in 1/12 of an hour.

Hence,

= 5/6 miles / 1/12 hour

= 5/6 miles ÷ 1/12 hour

= 5/6 miles × 12 hour

= 10 miles per hour

Therefore, In miles per hour, the number of miles Paula ran faster than Pepe is calculated as:

10 miles per hour - 8 miles per hour

= 2 miles per hour

Raymond was riding a zip-cable from the top of a viewing post. The cable is 65 yards long. The viewing post is 52 yards high and

grin007 [14]

In order to figure out the horizontal distance Raymond travels using his zip cable, we may simply apply Pythagoras theorem which is, for a right triangle:
hypotenuse² = base² + height²
base = √(hypotenuse² - height²)
base = √(65² - 52²)
base = 39 yards
Raymond will travel a horizontal distance of 39 yards.
