podryga [215]

Answer:

The small box contains 21 cans

Step-by-step explanation:

Represent the small box with S and the large with L.

For Estelle:

$3L + 5S = 170$

For the boy:

$4L + 4S = 184$

Required

Determine the cans in the small box

$3L + 5S = 170$ --- (1)

$4L + 4S = 184$ --- (2)

Divide (2) through by 4

$L + S = 46$

Make L the subject

$L = 46 -S$

Substitute 46 - S for L in (1)

$3L + 5S = 170$

$3(46 - S) + 5S = 170$

Open bracket

$128 - 3S + 5S = 170$

$128 + 2S = 170$

Collect Like Terms

$2S = 170-128$

$2S = 42$

Divide both sides by 2

$S = 21$

<em>Hence, the small box contains 21 cans</em>

I need help please help!

Blababa [14]

Answer:

50.5 m^3

Step-by-step explanation:

Volume of pyramid = 1/3 × base area × height.

Height: 11
Base Dimensions: 4.3 and 3.2

Area of Base:

$4.3 * 3.2$
$13.76$

Next, we multiply 13.76 by 11.

13.76 × 11
151.36

Lastly, divide by 3 and round to nearest tenth.

151.36 ÷ 3
50.453333..
≈ 50.5

Therefore, the answer is 50.5 m^3

A truck traveled a distance of 280 kilometers in 4 hrs.

erica [24]

In this question, it is necessary to first check all the details that are already provided in the question. Then after they are noted down the final thing required is to find the answer to the question by correct calculations.
Distance for which the truck traveled = 280 kilometers
Time taken to travel the given distance = 4 hours.
Then
Speed of the truck = Distance traveled/Time taken
= 280/4 km/hr
= 70 km/hr
So the truck was traveling at a speed of 70 kilometers per hour. This is the answer to both the questions that have been put up. So there is no need for any kind of second calculation.
