Find the missing length ‘x’

Answers

Answer 1

Answer:

x = 13

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here A = 55, h = 5. b₁ = x, b₂ = 9, then

[tex]\frac{1}{2}[/tex] × 5 × (x + 9) = 55

2.5(x + 9) = 55 ( divide both sides by 2.5 )

x + 9 = 22 ( subtract 9 from both sides )

x = 13

Hailey invested $1,700 in an account paying an interest rate of 2.2% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $2,590?

Answers

It would take approximately 19 years for the value of the account to reach $2,590.

How long would it take for the value of the account to reach $2,590?

The formula accrued amount in a compounded interest is expressed as;

A = P( 1 + r/n )^( n × t )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given that:

Principal P = $1,700Compounded monthly n = 12Interest rate r = 2.2%Accrued amount A = $2,590Time t = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 2.2/100

r = 0.022 per year.

Plug the given values into the above formula and solve for time t.

A = P( 1 + r/n )^( n × t )

t = In(A/P) / n[ In( 1 + r/n ) ]

t = In( $2,590/$1,700 ) / ( 12[ In( 1 + 0.022/12 ) ] )

t = 19.155 years

t = 19 years

Therefore, the time taken is approximately 19 years.

System of equations will be important here. We have two pieces of information: how many tickets were sold, and the total price.

A= adults, S = students

A + S = 155 (# of tickets)
7A + 3S = 645 (total profit)

S = 155 - A , based on the first equation

Now substitute S into the second equation.

7A + 3(155 - A) = 645

7A + 465 - 3A = 645

4A = 180

180/4 = 45 adult tickets sold.

peter buys 4 1/2 pounds of fertilizer for his front yard every 5 weeks. He uses the same amount every time he gardens. How many kilograms of fertilizer will he buy each year

Answers

I believe the answer is 21.23 kilograms.

Explanation
You take 52 and divide by 5 because you’re trying to figure out for the whole year. Then you take what 52 divided by 5 is and multiply by 4.5 since he buys 4.5 pounds every 5 weeks. Then you convert that number which is 46.8 into kilograms which gives you 21.22812

One of the spokes on the bicycle wheel broke and DJ wanted to fix it. What is the measurement of the bicycle spoke(Radius) if the circumference of the bicycle wheel is 50.24 cm?

Answers

Answer:

Radius = 7.995944341

Step-by-step explanation:

You use the circumference formula. C=2πr

Since you have the circumference 50.24 cm. You plug in the circumference.

50.24 = 2πr

You divide by 2 and get 25.12.

25.12 = πr

Then, you divide 25.12 by π.

Your answer is

7.995944341 = r
