The volume of concrete that was used to pour the sidewalk is 270 cubic meters and this can be determined by using the formula of volume.

Given :

A sidewalk is 15cm high, 30m wide, and 60m long.

The following steps can be used in order to determine the volume of concrete that was used to pour the sidewalk:

Step 1 - The formula of volume can be used in order to determine the volume of concrete that was used to pour the sidewalk.

Step 2 - The formula of volume is given below:

[tex]\rm V = L\times W \times H[/tex]

where L is the length, W is the width, and H is the height.

Step 3 - Now, substitute the values of the known terms in the above formula.

[tex]\rm V = 60\times 30 \times \dfrac{15}{100}[/tex]

Step 4 - Simplify the above expression.

V = 270 cubic meters

Therefore, the correct option is A).

Answer:

$505.385

Step-by-step explanation:

Given that:

Worker's one month salary is 4380

The number of working days in the month is not given ; However the average number of working days in a month usually range from 22 to about 26 days

Lets assume the number of working days for the firm in question is 26 days

Daily salary will be calculated as :

Monthly salary / number of working days

4380 / 26

= 168.46153

3 days salary :

168.46153 * 3

= $505.385

The remainder is 5 when 54 is divided by 7.

Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.

Given:

We have to divide 54 by 7.

So, the division is

                            7 | 54 | 7

                                  49

                              -_____

                                     5

Then, the remainder is 5 because we do not have number further and 5 is smaller than divisor.

Answer:

Number of week they have same amount = 4 week

Step-by-step explanation:

Given:

Amount Joe have = $14

Joe's saving per week = $10

Amount Josh have = $26

Josh saving per week = $7

Find:

Number of week they have same amount

Assume;

Number of week they have same amount = a

So,

(14 + 10a) = (26 + 7a)

3a = 12

a = 4

So,

Number of week they have same amount = 4 week

Step-by-step explanation:

V=pi r^2h

V=3.14x3^2x7

=197.82

Answer:

V ≈ 198 m³

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here diameter = 6, then radius r = 3 and h = 7 , then

V = 3.14 × 3² × 7 = 3.14 × 63 ≈ 198 m³ ( to the nearest whole number )

Answer:

Answer:

If using one pound of pumpkin the baker needs to use 4 pounds of flour mixture

Step-by-step explanation:

step 1: I am going to convert the measurements

into decimals

8/5=1.6

2/5=.4

step 2: I will use cross multiplication to find out how much pumpkin for one pound of flour

1.6=.4

 1=?

1*.4=.4/1.6=.25

step 3:  I will convert .25 into a fraction

.25=1/4

for every 1/4 pound pumpkin, I will use 1 pound of flour

which is why

If using one pound of pumpkin the baker needs to use 4 pounds of flour mixture

Answer:

640 yard²

Step-by-step explanation:

From the question,

The surface are of a triangular prism is given as

A = bh+2ls+lb.................. Equation 1

Where A = Surface area of the triangular prism, b = base of of the triangular face, h = height of the triangular face, l = length of the triangular prism, s =  length of one of the other sides of the triangle

Given: l = 17 yards, b = 12 yards, h = 8 yards, s = 10 yards.

Substitute these values into equation 1

A = [(12×8)+(2×17×10)+(17×12)]

A = 96+340+204

A = 640 Yard²

Answer:

4

Step-by-step explanation:

30*4=120 because 12=3*4 and 30*4 is basically 3*4*10, and since it's asking for the scale factor, we test to see if 12*4=48, which it does.

Answer:

8

Step-by-step explanation:

The formula for area is length x width or length x height, height and width mean the same thing in some problems such as this one. To find the height, you need to divide the area by the width. 38 divided by 4 3/4 = 8.
