Answer» Answer: 3.125m Step-by-step explanation: 3.125 metres This question is testing on finding the area of solids The area of a rectangle is l × w Where l is the length and w is the width We have been TOLD that a pit 13 centimeters long and 12centimetres wide was dug meaning we are supposed to FIND the area of the remaining part which was not dug To find the remaining piece which was not dug we find the area of the bigger rectangle minus the area of the smaller rectangle (78 m × 27 m) - (13m × 12m) 2106 m - 156 m = 1950 metres We have been told also that soil from the pit was spread up to a layer of 25 centimeters We can there find the total amount of soil from the pit. This soil was spread on the remaining area of the plot To find the total amount of soil we take the area of the remaining plot multiply by the layer of soil We first change the height into metres hope it helps you plzz mark me as ur brainliast ❤️❤️❤️ 25 CM ÷ 100 = 0.25 m 1950 × 0.25 = 487.5 m³ This area that we have found is the same as the area of the pit To find the height of the pit ,we divide it by the area of the rectangle forming the mouth of the pit. 487.5 ÷ 156 = 3.125 metres

Please give me right ans

Answer»

Answer:

3.125m

Step-by-step explanation:

3.125 metres

This question is testing on finding the area of solids

The area of a rectangle is l × w

Where l is the length and w is the width

We have been TOLD that a pit 13 centimeters long and 12centimetres wide was dug meaning we are supposed to FIND the area of the remaining part which was not dug

To find the remaining piece which was not dug we find the area of the bigger rectangle minus the area of the smaller rectangle

(78 m × 27 m) - (13m × 12m)

2106 m - 156 m = 1950 metres

We have been told also that soil from the pit was spread up to a layer of 25 centimeters

We can there find the total amount of soil from the pit.

This soil was spread on the remaining area of the plot

To find the total amount of soil we take the area of the remaining plot multiply by the layer of soil

We first change the height into metres

hope it helps you

plzz mark me as ur brainliast ❤️❤️❤️

25 CM ÷ 100 = 0.25 m

1950 × 0.25 = 487.5 m³

This area that we have found is the same as the area of the pit

To find the height of the pit ,we divide it by the area of the rectangle forming the mouth of the pit.

487.5 ÷ 156 = 3.125 metres

34.	the sum of two numbers is 80. If the larger number exceeds four times the smaller by 5, what is the smaller number?
Answer» ✬ Smaller Number = 15 ✬ Step-by-step explanation: Given: SUM of two numbers is 80. Larger numbers exceeds FOUR times the smaller by 5. To Find: What is the smaller number ? Solution: Let the larger number be x. Therefore, ➱ Smaller number = 80 – x A/q Larger number exceeds four times the smaller number by 5. $\implies{\rm }$ x = 4 $\times$ (80 – x) + 5 $\implies{\rm }$ x = 320 – 4x + 5 $\implies{\rm }$ x = 325 – 4x $\implies{\rm }$ x + 4x = 325 $\implies{\rm }$ 5x = 325 $\implies{\rm }$ x = 325/5 $\implies{\rm }$ x = 65 So, ➽ Larger number = x = 65 ➽ Smaller number = 80 – x => 80 – 65 => 15

34.

the sum of two numbers is 80. If the larger number exceeds four times the smaller by 5, what is the smaller number?

Answer»

✬ Smaller Number = 15 ✬

Step-by-step explanation:

Given:

SUM of two numbers is 80.
Larger numbers exceeds FOUR times the smaller by 5.

To Find:

What is the smaller number ?

Solution: Let the larger number be x. Therefore,

➱ Smaller number = 80 – x

A/q

Larger number exceeds four times the smaller number by 5.

$\implies{\rm }$ x = 4 $\times$ (80 – x) + 5

$\implies{\rm }$ x = 320 – 4x + 5

$\implies{\rm }$ x = 325 – 4x

$\implies{\rm }$ x + 4x = 325

$\implies{\rm }$ 5x = 325

$\implies{\rm }$ x = 325/5

$\implies{\rm }$ x = 65

So,

➽ Larger number = x = 65

➽ Smaller number = 80 – x

=> 80 – 65

=> 15
