Answer:The height of the building which caste a shadow 20.5 m in length is 17.5 m.

Step-by-step explanation:

Given : At a particular time of a day, a 7 high flagstaff castes a shadow which is 8.2 m long.

To find : What is the height of the building which castes a shadow 20.5 meters in length at the same moment?

Solution :

A 7 high flagstaff castes a shadow which is 8.2 m long.

i.e. Shadow of length 8.2 m = 7 m

The shadow of length 1 m = m

The shadow of length 20.5 m = m

The shadow of length 20.5 m = 17.5 m

Therefore, The height of the building which caste a shadow 20.5 m in length is 17.5 m.

<span>Tabia spent 15/24 of this week's allowance on gummy bears. She can calculate that by multiplying 3/4 times 5/6. To do that, she multiplies the top numbers of each fraction together (3 times 5 equals 15), and to get the top number of the fraction.

Answer:

see below

Step-by-step explanation:

To find the combined length of Pine and Elm and the lengths together

Pine +Elm

We are estimating by rounding to the nearest whole number

Pine is 2.7 so it rounds to 3 because we look at the .7 and since .7 is greater than .5 it rounds the 2 to 3

Elm is 8.9 so it rounds to 9 because we look at the .9 and since .9 is greater than .5 it rounds the 8 to 9

2.7 + 8.9 rounds to 3+9 = 12

12 is reasonable because the actual answer is 2.7+8.9 = 11.6 which rounds to 12

ruslelena [56]

Answer:

A. 8.

Step-by-step explanation:

The marginal product is the increase in output (units produced) resulting from employing one more worker. Therefore, the marginal product of the second worker (M2) is given by the difference between the total product with two workers and the total product with one worker.

$M_2 =32-24\\M_2 =8$

The answer is A. 8.

$\frac{ \frac{8}{5} + ( - \frac{5}{6}) }{ \frac{1}{6} } \\ = \frac{ \frac{8}{5} - \frac{5}{6} }{ \frac{1}{6} } \\ = \frac{ \frac{48- 25}{30} }{ \frac{1}{6} } \\ = \frac{ \frac{23}{30} }{ \frac{1}{6} } \\ = \frac{23}{30} \times 6 \\ = \frac{23}{5}$
