Answer:
525
Step-by-step explanation:
first we need to work out the percentage of the children who attended to to do this we need to add 47% with 32% which is 79%. Then you need to take away 79% from 100% which is 21%. After that you now know that 21% is the children who attended but you wanted to know how many children so to work this out you would find 21% of 2500 which would give you 525.

Solve for x in the diagram below.
9514 1404 393
Answer:
x = 20
Step-by-step explanation:
The sum of the given angle expressions is 90°, the measure of the right angle:
x + (3x +10) = 90
4x = 80 . . . . . . . . . subtract 10
x = 20 . . . . . . . . . . divide by 4
Answer:
x = 20
Step-by-step explanation:
Key skills needed: Complementary Angles, Equations
1) We are given this diagram and we want to find out x.
The 2 angles (One with the measure "x degrees" and the other with the measure of "3x+10") are complementary. This means that both their measures add up to equal the measure of a right, or 90 degrees.
2) This means we can make the equation --> [tex]x + 3x + 10 = 90[/tex]
To solve:
Combine like terms (3x + x = 4x) --> [tex]4x + 10 = 90[/tex]
To get "x" by itself, subtract 10 from both sides (90 - 10 = 80)
This means it would be --> [tex]4x = 80[/tex]
Divide by 4 from both sides (80 divided by 4 is 20) and get x = 20
Therefore 20 is your answer.

Larson uses 2 tablespoons (tbsp) of oil for every 5 tablespoons of vinegar in a science experiment. He uses a total of 20 tablespoons of vinegar. The tape diagram below represents this situation.
image 7ab5bfdf0ba844ca8e92c8aff1fdf52a
How many tablespoons of oil should Larson use?
Answer:
8 tablespoons
Step-by-step explanation:
your ratio is 5:2 so for every 5 we will need 2. so 5 times what is 20. well 4 so now we need to multiply 2 by 4 to get 8 and your ratio becomes 20:8.

Rhona can run at a rate of 6 miles per hour. Mira can run 8 miles in 6 hours. Who sis the faster runner
Answer:
Mira
Step-by-step explanation:
Rhona runs a measly 6 mph, nd Mira runs about 1.3. You gotta divide 8 by 6.
OR,
u can make common denominators. Make Rhona's 1 hour 6 hours, then multiply 6 by 6. Therefore, in 6 hours, Rhona runs 36 miles.
Evaluate f(x)=4x+5 when x=4.
21
Step-by-step explanation:
=4x+5
=4*4+5
=16+5
=21
The value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = 4x + 5
Plug x = 4
f(4) = 4(4) + 5
f(4) = 16 + 5
f(4) = 21
Thus, the value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.

Mark has a piece of wood that is 11 1/4 ft long. He cuts the wood into as many 2 1/2 ft pieces as he can. How long is the leftover piece of wood?
Answer:
1 1/4 ft
Step-by-step explanation:
First lets convert the fractions to decimals so it will be easier to divide. We need to divide to know how many leftover pieces of wood are there. 11.25 (11 1/4) divide by 2.5 (2 1/2) is 4 with the reminder of 1.25. So there are 4 (2 1/2 ft) wood pieces and 1 1/4 ft leftover piece of wood.

Eva and Jamir like to bake cookies. Eva baked 24 chocolate chip cookies, and Jamir baked p peanut butter
cookies. Together they baked a total of 56 cookies,
Write an equation to describe this situation.
How many cookies did Jamir bake?
Answer:
Step-by-step explanation:
1) 24+P=56
You then would subtract 24 from the left and move it to the 56 side of the equation.
2)P=56-24
You then take 56-24=32.
3) P=32
a half of whats johns age was 4 years ago is equal to one third of what will be in 5 years time. how old is john now?
Let x = John's age now
half of what johns age was 4 years ago: (1/2)(x-4)
is equal to one third of what it will be in 5 years time: (1/3)(x+5)
(1/2)(x-4) = (1/3)(x+5)
3(x-4) = 2(x+5)

Find the equation of the exponential function represented by the table below:
Answer:
y = 4 [tex](2)^{x}[/tex]
Step-by-step explanation:
For an exponential function in standard form
y = a [tex](b)^{x}[/tex]
To find the values of a and b, use ordered pairs from the table
Using (0, 4 ), then
4 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so
a = 4
y = 4[tex]b^{x}[/tex]
Using (1, 8 ), then
8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
2 = b
Thus
y = 4 [tex](2)^{x}[/tex] ← exponential function
The distance between 2 cities is 7,200 miles. How long will it take a plane that flies at 600 miles h to travel between the 2 cities?
Answer:
It would be 12 hours for the plane to go from a city to another/the other city
Step-by-step explanation:
(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)
If you would apply the formula for time then
7,200m ÷ 600m/h = 12 hours
The plane flying at 600 miles per hour can cover a distance of 7200 miles in 12 hours.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, The distance between 2 cities is 7,200 miles and a plane can fly 600 miles per hour.
∴ The time required to cover the distance of 7200 miles is,
= (7200/600) h.
= 72/6 h.
= 12 h.
