F is inversely proportional to d^2. When F=9, d=4 Work out d (positive value rounded to 2 DP) when F=6

Answers

Answer 1

Answer:

d = 4.90

Step-by-step explanation:

Given the following data;

F = 9

d = 4

For an inversely proportional relationship, we have;

F = k/d²

Now, we would find the constant, k;

9 = k/4²

k = 9*16

k = 144

Next, to find d, when F = 6

d² = k/F

d² = 144/6

d² = 24

Taking the square root of both sides, we have;

d = 4.90

Joe and Josh each want to buy a video game. Joe has $14 and saves $10 a
week. Josh has $26 and $7 a week. In how many weeks will they have the
same amount?

pls help and give a step by step explanation

Answers

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:

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.

A sidewalk is 15cm high, 30m wide and 60m long. The volume of concrete that was used to pour the sidewalk is


A. 270 m3
B. 2700 cm3
C. 27 m3
D. 270000 cm3​

Answers

It’s D because you have to multiply the height by the base and length so it makes 270000 cm3

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).

Answers

Solution:-

The remainder is 5 when 54 is divided by 7.

What is Division?

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.

A triangular prism is 17 yards long and has a triangular face with a base of 12 yards and a height of 8 yards. The other two sides of the triangle are each 10 yards. What is the surface area of the triangular prism?

Answers

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

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

What is the volume of this cylinder?

Answers

Step-by-step explanation:

V=pi r^2h

V=3.14x3^2x7

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 )

C

1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)

2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)

3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D

4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B
