Step-by-step explanation:

the outer left side is also 50 ft.

in inner (upper) left side is also 13 ft.

the bottom line is 10+20+11 = 41 ft

this is all possible because all the angles are clearly right angles (90°).

so, the perimeter is

2×(10+20+11) + 2×50 + 2×13 = 82 + 100 + 26 = 208 ft

Write a division equation that can be solved by multiplying each side by <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B

sveta [45]

For example:
(4/9) x=8

Now can solve this equation multiplying each side by 9/4.

(9/4)(4/9)x=(9/4)8
x=18

To check:
(4/9)(18)=(4*18)/9=72/9=8

The question is:

A fair was attended by 350 people of which two thirds are adolescents and a quarter adults and a fifth are children from 10 to 12 what amount corresponds to adults .

Solution:

Total number of people attending the fair is, <em>N</em> = 350.

The proportion of adults is: P (Adults) = <em>p</em> = 0.25.

Compute the number of adults in the fair as follows:

$\text{Number of adults in the fair}=N\times p$

$=350\times 0.25\\\\=87.5\\\\\approx 88$

Thus, there are approximately 88 adults.

Evgesh-ka [11]

Answer:

(Thermometer B reading - Thermometer A reading)

The thermometer reading aren't given in the question.

However, hypothetically.

The difference between two temperature values (morning and evening values) would be :

Temperature in the evening - morning temperature

Therefore,

If ;

Thermometer A reading = morning temperature

Thermometer B reading = evening temperature

Difference in the temperature :

(Thermometer B reading - Thermometer A reading)
