in a class of c children there are 16 boys what fraction of the class are boys
Answer:
16/c of the class are boys
Step-by-step explanation:
If there are a total number of children, c, and 16 of them are boys, you are going to put the total number of children on the bottom of the fraction as the denominator and put the number that are boys on top of the fraction as the numerator.
(I hoped this helped)
Answer:
Step-by-step explanation:
if the number of the children is c and we have 16 boys
the fraction will be c/16

how do you find y-intercept of the line of a graph
Answer:
If you know what the formula y = mx +b is, then you know that mx is the slope and b is the y-intercept.
Let`s suppose the equation is y = 2x + 1. The line should be intersecting with the coordinate (0, 1) on it`s way across.
The y axis will ALWAYS be the vertical line. Whatever coordinate the line crosses on the y-axis is the y-intercept.
The y-intercept can also be a negative number.
Hope that helps. If you have any questions just comment them.
Your friend loans you $550 to buy a PS5. They are going to charge you 3% interest rate. After some time you pay your friend back the $550 plus $33 in interest. How long did it take you to pay your friend back?
Answer:
2 years
Step-by-step explanation:
3% of $550 = 0.03 * $550 = $16.50
3% interest on $550 for 1 year is $16.50
$33/$16.50 = 2
Since 2 * $16.50 = $33, the loan was for 2 years.

What match the decimal with its equivalent percent.
0.0402
Answer:
The answer would be 4.02% or simply 4%
Step-by-step explanation:
When you have a decimal like 0.0402 for example you move the decimal point to the right twice to get the percentage. Another example would be if you had the decimal 0.08 you would have the percentage 8%. Hope this helped!! If you have the time please mark brainlest?

how to tell if a sequence is arethmetic
Answer:
If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference, denoted by the letter d.

Answer:B
Step-by-step explanation:first subtract 2x from
3x+2=2x+4 Both sides .subtract 2 from
-2 -2 Both sides.after divide 1x from 1x
1x+2=4 To cancel 1.divide 2 and 1.then
-2 -2 You will get 2.

A 5 foot tall person walks away from a 12 foot tall lamppost at a constant rate of 4 feet per second. What is the rate that the tip of the shadow moves away from the lamppost when the person is 9 feet away from the pole?
Solution :
Given :
The height of the person is 5 foot.
The height of the lamppost is 12 foot.
Speed of the person away from the lamppost = 4 ft/s
Let the distance of the tip of the shadow of the perosn to the pole at t seconds after the person started walking away from the pole be d(t).
By similarity of the triangles, we see that
[tex]$\frac{12}{d}=\frac{5}{x}$[/tex] .................(i)
Here x is the distance from the person to the tip of the shadow. As it is given the speed of the person is 4 ft/s, then the distance of the person from the pole 4t. So we have,
x = d - 4t .............(ii)
Putting (ii) in (i) and solving for d is
d(t) = 6.85 t
So now if we derive d(t), we will get the wanted rate of the tip of the shadow.
∴ d'(t) = 6.85 ft/s

Answer:
Where is the graph?
Step-by-step explanation:
Solve the simultaneous equations
2x + 5y + 11 = 0
3x - y-8= 0
Answer:
x = 1[tex]\frac{12}{17}[/tex], y = -2[tex]\frac{15}{17}[/tex]
Step-by-step explanation:
2x + 5y + 11 = 0 --- Equation 1
3x - y - 8 = 0
15x - 5y - 40 = 0 --- Equation 2
Equations 1+2: 2x + 5y + 11 + 15x - 5y - 40 = 0 + 0
17x - 29 = 0
17x = 29
x = 29 ÷ 17
x = 1[tex]\frac{12}{17}[/tex]
Substitute x = 1[tex]\frac{12}{17}[/tex] into Equation 1:
2x + 5y + 11 = 0
2(1[tex]\frac{12}{17}[/tex]) + 5y + 11 = 0
3[tex]\frac{7}{17}[/tex] + 5y = -11
5y = -11 - 3[tex]\frac{7}{17}[/tex]
= -14[tex]\frac{7}{17}[/tex]
y = -14[tex]\frac{7}{17}[/tex] ÷ 5
y = -2[tex]\frac{15}{17}[/tex]
which function represents the graph?
Answer:
y=3sin(x)
Step-by-step explanation:
The best way to check if it's right is to use a graphing calculator. The negative trigonometric functions are going upwards from 1pi to 2pi and the positive ones are going downwards from 1pi to 2pi. Since the cos sign is shifted two units left, we can assure that 3sin(x) gives the most accurate answer.
please help. What is the solution to the system of equations below?
y = 3x – 2
X + y = 6
Answer:
A. (2,4)
Step-by-step explanation:
use the substitution method.
for the second equation, subtract x on both sides to get y = 6-x
substitute that into the first equation
6 - x = 3x - 2
add x on both sides: 6 = 4x-2
add 2 on both sides: 4x = 8
divide by 4: x = 2
y = 6-2 = 4

A. (2, 4)
