At the World Cup, 25% of the teams are from South American countries. If there are 40 teams in the World Cup, how many are from South American countries? Construct a double number line if needed.
Answer:
10
Step-by-step explanation:
100% = 40 teams
1% = 40 ÷ 100 = 0.40
25% = 0.40 x 25 = 10
Answer:
10
Step-by-step explanation:
100%/4=25%
40/4=10
You have to divide 100% by 4 because 25 goes into 100 four times.
What ever you do on the bottom or top you to do it top or bottom.
So 40 divide by 4 is 10.
Then you have you answer.

1.) What is the average rate of change between x=2 and x=5?
2) What is the average rate of change between x=3 and x=6?
3) What is the average rate of change between x=2 and x=4?
Answer:
Rate of change = 150%
Rate of change = 100%
Rate of change = 100%
Step-by-step explanation:
Find:
Rate of change
x=2 and x=5
x=3 and x=6
x=2 and x=4
Rate of change = [(5-2)/2]100
Rate of change = 150%
Rate of change = [(6-3)/3]100
Rate of change = 100%
Rate of change = [(4-2)/2]100
Rate of change = 100%

Which of the following points solves the system shown below?
y = 5x -9
y = -2x + 12
Choose from the following...
1) (1, -4) 2) (2,8) 3) (3,6) 4) (-3, 18)
Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)

what is the domain of the function a^x
Answer:
The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
Step-by-step explanation:
Answer:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
Step-by-step explanation:
Identify the input values.
Since there is an even root, exclude any real numbers that result in a negative number in the radicand. ...
The solution(s) are the domain of the function.

Step-by-step explanation:
3x-4y=16 slope and intercept form
Answer:
y=3/4x-4
Step-by-step explanation:
The form is y=mx+b so isolate y
-4y=16-3x
y=-16/4-3x/-4
y=3/4x-4
Answer:
y = 3/4x - 4
Step-by-step explanation:
Slope intercept form: y = mx + b
3x - 4y= 16
-4y = 16 - 3x
4y = -16 + 3x
y = -4 + 3/4x
y = 3/4x - 4
When you have an x value of zero in a point like this one (0,8) where is the point located on the graph? When you have a y value of zero in a point like this ( -3,0) where is the point located on the graph?
plz explain
Answer:
well I don't have a picture to explain it but (0,8) would be on the y axis and 8 on the x-axis ( it would go up 8 times and stay on the same line)
it would be -3 on the y axis and it wouldn't move up or down (move 3 points to the left)
Step-by-step explanation:
(x,y) when the x is 0 it doesn't move on the x-axis (left or right) and when it is 0 it doesn't move on the y-axis (up or down)
hope that makes sense!
Sam has striped and spotted socks in his draw in
the ratio 3:7. He has 6 striped socks.
How many spotted socks does he have?
Answer:
14 spotted socks
Step-by-step explanation:
Sam has 3 units of striped socks and 6 of them.
Find one unit.
3 units = 6
1 unit = 6 ÷ 3 = 2
Sam has 7 units of spotted socks.
7 units = 2 x 7 = 14
-. A scale model of an oil tanker truck can hold 1 gallon of oil. If a trucking company wants the full size-truck to hold 8,000 gallons of oil, what scale factor must they apply to the model.
Answer: 8,000
Step-by-step explanation:
If the scale model can only hold 1 gallon of oil but the full size truck needs to hold 8,000 gallons, you can find a relevant scale factor using cross multiplication:
1 : 1
x : 8,000
x = 8,000
They should apply a scale factor of 8,000.
The scale factor that they must apply to the model is 1 is to 8000.
How to calculate scale factor:A scale factor of a given quality is what is multiplies the quantity to give a total.
The original content of the oil tanker truck is 1 gallon
The new full size truck is to hold 8000 gallons
That is 1 × 8000 of the old oil tanker truck.
Therefore, the scale factor that they must apply to the model is 1 is to 8000.

FIND M∠R (GIVING BRAINLIEST, 25 PTS)
Answer:
76Step-by-step explanation:
to understand thisyou need to know about:trianglesequationPEMDASgiven:[tex]M\angle T=2x+2[/tex][tex]M\angle R=3x+1[/tex]tips and formulas:this is an isosceles triangle since two sides are equal therefore [tex]\angle T=\angle S[/tex]a triangle contains 180°let's solve:according to the question
2x+2+2x+2+3x+1=180
solve:
collect like terms:7x+5=180substract 5 from both sides:=>7x+5-5=180-5=>7x=175divide both sides by 7: =>7x/7=175/7x=25given:
M∠R=3x+1
substitute the value of x
3×25+1
75+1
76
Answer:
M∠R=76°
Step-by-step explanation:
First, I realized that ∠S was equal to ∠T, meaning ∠S=2x+2. I then added all 3 angles together and set them equal to 180, seeing the angles of a triangle must add up to 180 (2x+2+2x+2+3x+1=7x+5=180)
After that, I subtracted 5 from 180 and then divided by 7 to get x=25. I then solved the equation 3x+1 by plugging 25 in for x and ended up with 76 as my final answer.

Given:
The equation is
[tex]\dfrac{2a-4}{3}=8[/tex]
To find:
The reason for second step.
Solution:
We have,
[tex]\dfrac{2a-4}{3}=8[/tex]
Using multiplication property of equality, multiply both sides by 3.
[tex]3\left(\dfrac{2a-4}{3}\right)=3(8)[/tex]
[tex]2a-4=24[/tex]
Using addition property of equality, add 4 on both sides.
[tex]2a-4+4=24+4[/tex]
[tex]2a=28[/tex]
Using division property of equality, divide both sides by 2.
[tex]\dfrac{2a}{2}=\dfrac{28}{2}[/tex]
[tex]a=14[/tex]
So, the reason for second step is multiplication property (=).
Therefore, the correct option is D.

What is the question asking for??
Step-by-step explanation:
area of the square=7*10=70cm2
area of the semi circle=πr^2/2
=22/7*5*5/2
. =39.25cm2
total area=39.25+70=109.25cm2
Point $Y$ is on a circle and point $P$ lies outside the circle such that $\overline{PY}$ is tangent to the circle. Point $A$ is on the circle such that segment $\overline{PA}$ meets the circle again at point $B$. If $PA = 15$ and $PY = 9$, then what is $AB$? [asy] unitsize(2 cm); pair A, B, P, Y; Y = dir(130); A = dir(20); B = dir(180); P = extension(Y, Y + rotate(90)*(Y), A, B); draw(Circle((0,0),1)); draw(Y--P--A); label("$A$", A, E); label("$B$", B, SW); label("$P$", P, W); label("$Y$", Y, N); [/asy]
Answer:
48/5
Step-by-step explanation:
By power of a point on P, we have PB * PA = PY^2. Therefore,
PB = PY^2/PA = 9^2/15 = 27/5. Then AB = PA - PB = 15 - 27/5 = 48/5
Problem: A pole is being held up with a 10 meter rope. The cable is making a 42° of elevation from the ground to
the top of the pole. What is the distance from the base of the pole to the base of the rope ? Round your answer
to the nearest tenth of a meter.
Answer:
x = 7.4
Step-by-step explanation:
cos(42°) = x/10 or distance from bases / rope length
Using the calculator find the value of cos(42°):
cos(42°) = 0.74 = x/10
Find x using the value of cos(42°):
x/10 = 0.74
x = 7.4
