The area of a rectangular field is 48m2 and one of its sides is 6m . How long will a lady take to cross the field diagonally at the rate of 20m/min

Answers

Answer:

It will take her approximately 28 seconds to cross the diagonal of the pitch

Step-by-step explanation:

If we can find the length of the diameter of the field (in Metres), we can easily find the time it takes her to cross this length using motion equations.

Step one: Find the length of the field from its area.

The field is rectangular in shape. The area of the field is 48m^2. To get the area of the field, we had to multiply its length and its breadth.

i.e area = length X breadth.

Let us assume that the breadth = 6m

its length will be area / breadth = 42/ 6 = 7m

The length of the pitch = 7 m

Step Two: Find the length of the diagonal using Pythagoras' theorem.

From Pythagoras'theorem, the length of the diagonal can be obtained by

[tex]diagonal = \sqrt{l^2 +b^2}[/tex]

[tex]diagonal = \sqrt{6^2+ 7^2} = 9.22m[/tex]

The length of the diagonal is 9.22m

Step three: Find the time using her speed and the distance she needs to cover.

Time = distance / speed

time = 9.22 /20 = 0.46 minutes

It will take her approximately 28 seconds to cross the diagonal of the pitch

To get from (16,12) to (12,9) you would multiply both 16 and 12 by 3/4 to get 12 and 9.

3/4 (12x+8)=-13- (2x+3)

Answers

Answer: = − 2

Step-by-step explanation:

Remove parentheses.

3/4 (12x+8)=−13−2x−3

Simplify 3/4(12x+8) to 3(12x+8)/4.
3(12x+8)/4=-13-2x-3

Factor out the common term 4.
3x4(3x+2)/4=-13-2x-3

Simplify 3×4(3x+2) to 12(3x+2).
12(3x+2)/4=-13-2x-3

Simplify 12(3x+2)/4 to 3(3x+2)
3(3x+2)=−13−2x−3

Simplify −13−2x−3 to −2x−16
3(3x+2)=−2x−16

Expand
9x+6=−2x−16

Add 2x to both sides.
9x+6+2x=−16

Simplify 9x+6+2x to 11x+6.
11x+6=−16

Subtract 6 from both sides.
11x=−16−6

Simplify −16−6 to −22
11x=−22

Divide both sides by 11.
x=− 22/11

Simplify 22/11 to 2.
x=−2

Change means “difference in price”. Difference means subtraction.....so:
New price - old price = difference

If you want per year, there were 5 years between prices so divide by 5:

Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Gabriel remembers he has a coupon for $2 off his bill.

Gabriel has $30 to pay for the groceries. What simplified expression would represent the amount of change he should receive

Answers

Answer:

32 - 2.5x - 2y

Step-by-step explanation:

He bought 2.5 pounds weight of apples for x dollars a pound. Thus, cost is 2.5x.

He bought 2 bags of lettuce for y dollars each. Thus, cost is 2y

Total bill cost = 2.5x + 2y

We are told he has a coupon for $2 off his bill.

This means the amount he will pay will now be;

2.5x + 2y - 2

Gabriel has $30 to pay for the groceries.

Thus, his change will be;

30 - (2.5x + 2y - 2)

This gives;

32 - 2.5x - 2y

The height of a rectangular pyramid is 4 inches

The base of the pyramid measures 9 inches by 9 inches.

We need to find the volume of the rectangular pyramid. The formula for the volume of the rectangular pyramid is given by :

[tex]V=\dfrac{lbh}{3}[/tex]

Substitute all the values,

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.

At the end of the 4 years, how much interest in dollars and cents did the account earn?

Answers

Answer:

$1105

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 6500 × 0.0425 × 4 = 1105

I = $ 1,105.00

The simple interest accumulated

on a principal of $ 6,500.00

at a rate of 4.25% per year

for 4 years is $ 1,105.00.

Rearrange to make subject x 4(x-3)/a=y

Answers

Answer:

answer is x = ay + 12/4

Step-by-step explanation:

first we cross multiply on both sides which will give us this

4( x -3)=ay

we then open the brackets by multiplying 4 with x and -3 which gives

4x - 12= ay

then take 12 to the other side

4x - 12+12= ay + 12

4x = ay + 12

divide 4 on both sides

4x /4= ay + 12/ 4

therefore x = ay + 12/ 4
