Step-by-step explanation:
I wasn't sure if 16mm was the radius or diameter. If it's the diameter then use the first answer. If it was the radius then use the second answer.
In order to find the area of a circle use equation
[tex]A=\pi r^2[/tex]
r = radius, which is half of the line along the circle. If you have the diameter simply divide it by two and you have the radius.

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During one particular week, the two cars went a combined total of 1100 miles, for a total gas consumption of 35 gallons. How many gallons were consumed by each of the two cars that week?
Answers
Answer:
Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.
Step-by-step explanation:
fuel efficiency = distance in miles/gallons of gas
fuel efficiency * gallons of gas = distance in miles
Car 1: 20 mpg
Car 2: 40 mpg
Total miles: 1100
Miles of Car 1: x
Miles of Car 2: 1100 - x
Total gallons: 35
Gallons for Car 1: y
Gallons for Car 2: 35 - y
Car 1:
fuel efficiency * gallons of gas = distance in miles
20 * y = x
Car 2:
fuel efficiency * gallons of gas = distance in miles
40 * (35 - y) = 1100 - x
20y = x
1400 - 40y = 1100 - x
20y = x
x = 40y - 300
40y - 300 = 20y
20y = 300
y = 15
35 - y = 35 - 15 = 20
Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.

Answers
Answer:
m = 8.2 × 10³ grams
Step-by-step explanation:
Given that,
The weight of a monkey = 8.2 kilograms.
We need to convert its mass from kilograms to grams.
We know that,
1 kg = 1000 grams
or
1 kg = 10³ grams
In 8.2 kg,
8.2 kg = 8.2 × 10³ grams
Hence, the weight of the monkey is equal to 8.2 × 10³ grams.

Hi!
ok so the Pythagorean theorem is
[tex]c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10[/tex]
so the other side is 10.
the square 8 is 8*8
and square 6 is 6*6
so the other square is 10*10=100.
so the area of the blank square is 100.

Three people take 2 hours to deliver leaflets to 270 houses.
Assuming all people deliver leaflets at the same rate, how long will it take five people to deliver
leaflets to 405 houses?
Give your answer in hours and minutes
Answers
Answer:
1 hour and 48 minutes
Step-by-step explanation:
270/2 hours = 135 per hour for 3 people
135/3 people = 45, so each person delivers 45 per hour
45 x 5 people =225 per hour
405/225 = 1.8 hours
It will take 1.8 hours for five people to deliver leaflets to 405 houses.
Given that, 3 people take 2 hours to deliver leaflets to 270 houses.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here,
270/2 hours = 135 leaflets per hour for 3 people
135/3 people = 45, so each person delivers 45 leaflets per hour
45 x 5 people =225 per hour
405/225 = 1.8 hours
Hence, it will take 1.8 hours for five people to deliver leaflets to 405 houses.

The sum of two numbers is 147. The difference of the two numbers is 25.
What are the two numbers? Show your work.
Answers
x + y = 147
x - y = 25
I always found second setting that second equation up was hardest. How do I know which one comes first? You just keep them in the same order as the first math equation.
So let’s solve for x in terms of y:
x - y = 25
x = 25 + y
Then substitute that into your first equation:
x + y = 147
(25 + y) + y = 147
2y = 122
y = 61
x = 25 + y = 25 + 61 = 86

enta al 4% de interés anual y otra al 5% anual. Calcula ambas partes
que el capital acumulado al cabo de un año es de $9,400.00 dólares.
Answers
Answer:
La respuesta al ejercicio es:
$4,000.00 al 5% anual.$5,000.00 al 4% anual.Step-by-step explanation:
Teniendo en cuenta que el capital inicial es de $9,000.00 y el capital tras un año es de $9,400.00, se identifica en primera instancia que la ganancia gracias al interés anual fue de $400, por lo cual se pueden tener en cuenta las siguientes variables:
x = monto de dinero al 5% anual.y = monto de dinero al 4% anual.Y el siguiente sistema de ecuaciones:
x + y = 9000x * 5% + y * 4% = 400En la segunda ecuación, cambiaremos los porcentajes para facilitar los cálculos posteriores:
2. x * 0.05 + y * 0.04 = 400
Lo cual también se puede representar como:
2. 0.05x + 0.04y = 400
Procedemos a despejar una variable, en este caso despejaré la variable y de la primera ecuación:
x + y = 9000y = 9000 - xY la reemplazaré en la segunda ecuación:
0.05x + 0.04y = 4000.05x + 0.04 (9000 - x) = 400Ahora operamos:
0.05x + 360 - 0.04x = 400Restamos las variables x:
0.01x + 360 = 400Y despejamos el valor real de x:
0.01x = 400 - 360x = 40 / 0.01x = 4000Ya que x es el monto de dinero puesto al 5% anual, ahora sabemos que dicho monto fue $4,000.00, por último, reemplazamos este valor en la primera ecuación para identificar el valor de y:
x + y = 90004000 + y = 9000y = 9000 - 4000y = 5000Por último, sabemos que el monto de dinero puesto al 4% fue $5,000.00.
