The shower block on the campsite has an area of 144 m2 The length of the shower block is 24 m.What is the width?

1 answer:

8 0

Since the shower block is in the form of a rectangle. The shower block has an area of 144 $m^{2}$ . It has a length of 24m. We need to calculate the width of the shower block.

Area of rectangular shower block = length $\times$ width

144 $m^{2}$ = 24 m $\times$ width

width = $= \frac{144m^{2}}{24m}$

width = 6m

So, the width of the shower block is 6 meters.

If 2 liters of sea water contain 70 grams of salt, how much salt is in 32 liters of sea water?

OLga [1]

Answer:

1120 grams

Step-by-step explanation:

The amount of sea water is directly proportional to the amount of salt in the water.

Let the amount of sea water be W and the amount of salt be S.

This means that:

W α S

=> W = kS

where k = constant of proportionality

2 liters of sea water contain 70 grams of salt Therefore:

2 = k * 70

k = 2 / 70 = 1/35

Therefore, for 32 liters of sea water:

32 = 1/35 * S

S = 35 * 32

S = 1120 grams

There are 1120 grams of salt in 32 liters of water.

For the data set given below, calculate the 70th percentile. (answer with an integer or decimal.) 24 45 52 78 90 120 34 67 111 1

Mashutka [201]

we know that

To calculate the percentile of a data set, we should first order all the values in the data set from smallest to largest.

[10,24,34,45,52,67,78,90,111,120]

As their are
10
data points

and
70% of this is
(70/100)*10=7

Take the index and the next greatest number and find the average.

Because,the index is a whole number

[10,24,34,45,52,67,78,90,111,120]

(78+90) /2=84

70th
percentile is equal to 84

the answer is

The 70th percentile is 84
