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.
can anyone help me? I'm so lost on this question. thanks!!
Answer:
a. -21
b. -16
c. -11
d. -9
Step-by-step explanation:
if x is less than -2, then u have to use the equation 5(x)-1
if x is greater than or equal to -2, then you have to use the equation (x)-9
Answer:
Step-by-step explanation:
This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.
So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.
f(-4)=5(-4)-1=-20-1=-21
f(-3)=5(-3)-1=-15-1=-16
Since the second two x values are not less than -2, you sub the x values into the second equation x-9
f(-2)=-2-9=-11
f(0)=-0-9=-9
On a map, 1 inch equals 5 miles. Two cities are 3 inches apart on the map. What is the actual distance between the cities?
The actual distance between the cities is ___ miles.
Answer:
15
Step-by-step explanation:
cross multiplying, [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{x}[/tex]
then it would be 15 =1x
and 1x is basically just one, so 15 = x
find the value of y
Answer:
Step-by-step explanation:
[tex]sin90/10=sin45/y\\ \\ y=10sin45\\ \\ y=5\sqrt{2}[/tex]
Answer:
The answer is
[tex]5 \sqrt{2} [/tex]
Step-by-step explanation:
By using Pythagoras
Then
[tex] {y}^{2} + {y}^{2} = {10}^{2} \\ 2 {y}^{2} = 100 \\ {y}^{2} = 50 \\ y = \sqrt{50} = \sqrt{2 \times 25} = 5 \sqrt{2} [/tex]
The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?
Answer:
6x-4
Step-by-step explanation:
the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter
11x-7 = 4x+2 + x-5 + y
solve for y
11x-7 = 5x -3 + y
11x-4 = 5x + y
6x-4 = y

Rebecca ran 21 miles in 5 hours. If she ran at a constant speed, how many miles did she run in 2 hours? 8.4 miles 42 miles 4.2 miles 1.2 miles
Answer: 8.4 miles
Step-by-step explanation:
d = rt
Solve for her rate
21 = 5r
r = 21/5
r = 4.2
Solve for if the time is 2 hours and rate (solved previously) is 4.2
d = 4.2*2
d = 8.4
The distance traveled by Rebecca in 2 hours is given by d = 8.4 miles and the speed is S = 4.2 miles / hour
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the total distance ran by Rebecca be D = 21 miles
The time taken by her to travel 21 miles T = 5 hours
So , the speed of Rebecca S = D / T
On simplifying , we get
S = 21/5
S = 4.2 miles per hour
Therefore , the speed of Rebecca is 4.2 miles / hour
Now , let the time taken be T₂ = 2 hours
So , the distance traveled in 2 hours , D = ST₂
D = 4.2 x 2
D = 8.4 miles
Hence , the distance traveled is 8.4 miles

What is the perimeter of JKL?
Answer:
The perimeter of JKL is 60 units.
Step-by-step explanation:
The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?
A. $2.15; $2.83
B. $0.40; $5.13
C. $0.40; $1.08
D. $1.75; $2.15
Answer:
A. $2.15; $2.83
Step-by-step explanation:
2.83
c = 0.4. * 2.7 + 1.75
=> c = 2.83
4(2.7)+1.75
1.08+1.75=2.83
$2.83 is correct.
c=0.40(2.7)+1.75
c=1.08+1.75
c=2.83
Answer:
2.83 dollars
Step-by-step explanation:
Fixed charges made by the taxi company for a ride =
Additional charge for each mile travelled =
Hence equation for cost is given by
where m is thenumber of miles travelled.
To find out the charge for a 2.7 mile ride substitute m = 2.7
Total cost for 2.7 mile ride is 2.83 dollars

Which type of function is most likely to model these data?
A
linear function with positive rate of change
O
B
linear function with negative rate of change.
non-linear function that decreases then increases
D
non-linear function that increases then decreases
Answer:
D
Step-by-step explanation:
I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.
