Joshua drove his car a distance of 321.7 miles, and it required 13.6 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answer:
1005.68 litres
Step-by-step explanation:
Steps to answering this question
Convert miles to kilometers and gallons to litresThen divide the converted miles by the converted gallons Multiply the value gotten from the above step by 100 km1 gallon = 3.78541 litres
13.6 gallons x 3.78541 = 51.48 litres
1 mile = 1.60934 km
321.7 miles x 1.60934 = 517.72 km
Litre needed per kilometer = 517.72 km / 51.48 = 10.06
Litres needed for 100 km = 100km x 10.06 = 1005.68 litres

Answer:
$180.
Step-by-step explanation:
First lets find the interest rate.
6.1 ÷ 100 = 0.061
0.061 x $200 = 12.2
based on the calculations, 12.2 is our interest rate in a year. Now lets find the interest rate in 15 years.
12.2 x 15 = $183
So $183 is our precise interest rate in 15 years, but lets round the interest rate to the nearest 10 dollars. Therefore, $180 is our answer.

What is the measure of the smaller of two complementary angles if one angle is 4x and the other is 2x + 18?
Answer:
42°
Step-by-step explanation:
4x + 2x + 18 = 90 because they are complementary angles (add up to 90°)
reduce:
6x = 72
x = 12
one angle = 4(12) = 48°
other angle = 2(12) +18 = 42°
mia hired a moving company, it charged 500$ for service mia give them a 16% tip.How much did she tip the movers,
Answer: 80 dollars
Step-by-step explanation:
You can find a percentage with one of two ways.
For hundreds like this, oftentimes it's quicker and more simple to think of it as just 100. The proportion from 100 to 500 is just 5. 16% of 100 is 16. So, multiply 16 * 5. You would get 80.
The second method is you can use 0.16 * 500. It's the more conventional method, and you get 80, like the last method.

In kite PQRS, m_OPO = 50° and m_ORO = 70°. Find m2PSR
Answer:
m<PSR = 60°
Step-by-step explanation:
Given:
m<OPQ = 50°
m<ORQ = 70°
Required:
m<PSR
Solution:
m<PQR + m<OPQ + m<ORQ = 180° (Sum of triangle)
m<PQR + 50 + 70 = 180 (Substitution)
m<PQR + 120 = 180
m<PQR = 180 - 120
m<PQR = 60°
One of the properties of a kite states that the angles where the unequal sides meets are congruent to each other. Therefore:
m<PSR = m<PQR
m<PSR = 60° (substitution)

Sarah buys a car for £44,000.
It depreciates at a rate of 4% per year.
How many years will it take to be worth less than £40,000?
Answer:
2.3 years or 2 and a half years
Step-by-step explanation:
bc 4% of 44000 is 1760 and we multiply that by 2.5 and get 4400 and minus that by 44000 and get 39600
The number of years it would take for the car to be worth less than £40,000 is 2.38 years.
When would the car be worth less than £40,000?Deprecation is when the value of an asset declines with the passage of time as a result of wear and tear.
Number of years = (In fv /pv) / r
FV = future valuePV = present valuer = rate of depreciation(In 40,000 / 44,000) / 0.04 = 2.38 years

Step-by-step explanation:
First, we need to find the volume of the pyramid. The formula for its volume is pictured below. We know all the sides and dimensions of the pyramid, so that is why we are doing this first.
14 * 4 * 12 = 672
672 divided by 3 is 224. The volume of the pyramid is 224 in cubed.
Now, we need to find the area of the rectangular prism. We can use that and divide the volume of the pyramid with it. Doing so will give us the value of x.
8 * 7 = 56.
224 divided by 56 = 4
X equals 4.
