A circular race track is 62.8 miles around. A driver is moving at 5 miles an hour driving from the outside to the center of the track. How long will it take for him to arrive?
Calculate the time it takes to travel to the center.
G I V E N
Speed of driver = 5 miles/hours
Distance to be covered = 62.8 miles
F O R M U L A ~ U S E D
Speed = Distance/Time
S O L U T I O N
Time = Distance/Speed
= 62.8 miles / 5 miles / hour
= 12.56 hours
It will take 12.56 hours to cover 62.8 miles, if the driver is moving
with 5 miles/hours

Write a linear equation that gives the rule for this table.
Hint: Linear Functions are of the form y=mx+b
Answer:
y=x
Step-by-step explanation:
If we look at this then this is a y=mx+b graph
first lets find the rise/run
so rise = how much it goes up and run = how much it goes right or left
the rise/run of this graph is 1 because each time it goes one up it goes one right.
B= y intercept and the y intercept is 0
So it is y=1x+0 or y=x
answer = y=x

what is 15% of 80? use an equation to solve.
Answer:
1215. percent *80 =
(15.:100)*80 =
(15.*80):100 =
1200:100 = 12
Now we have: 15. percent of 80 = 12
Percentage solution with steps:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with
Step 3: From step 1 above
Step 4: Similarly
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives

Robin was given a $40 monthly allowance. She wants to go to the movies as many times as possible and have at least $12.50 left at the end of the month to go to a concert. A movie ticket costs $5. How many times can she go to the movies?
Answer:
5 times
Step-by-step explanation:
5*5 is 25
40-25=15$ left
any more movie tickets would be too much money spent
If Robin was given a $40 monthly allowance. She wants to go to the movies as many times as possible and have at least $12.50 left at the end of the month to go to a concert. A movie ticket costs $5. Then she can go six times to the movies.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Robin was given a $40 monthly allowance.
She wants to go to the movies as many times as possible and have at least $12.50 left at the end of the month to go to a concert.
The amount spent on movies
40-12.5
$27.5
A movie ticket costs $5.
We need to find how many times can she go to the movies.
To find this we need to divide $27.5 by 5
$27.5/5=5.5
Robin can go 6 times to the movies.

Select the correct answer.
Solve the system of equations.
y = x + 3
[tex]y=x^{2} +7x+8[/tex]
A.
(-1,-4) and (-5,-8)
B.
(-1,2) and (-5,-2)
C.
(1,4) and (5,8)
D.
(-1,-2) and (-5,2)
Answer:
B. (-1,2) and (-5,-2)
Step-by-step explanation:
Substitute x + 3 in for y in the second equation. you get
[tex]x + 3 = x^{2} + 7x + 8\\x^{2} + 6x + 5 = 0[/tex]
(x + 1)(x + 5) = 0
x + 1 = 0 or x + 5 = 0
x = - 1 or x = -5
Using the first equation, let x = -1 and x = -5 in order to get the corresponding values for y
y = -1 + 3 = 2 and y = -5 + 3 = -2
So, B is the correct answer.
Find the unknown angle
Answer:
77 degrees
Step-by-step explanation:
Right triangles always add up to 180 degrees. We know that one angle is 23 degrees, angle A is missing, and the last angle is a right angle which is equal to 90 degrees. Knowing what we know, we must subtract the two known angles from 180 to get angle A.
180 - 90 = 90
90 - 23 = 77
Angle A is equal to 77 degrees.

Simon wants to find out which shop has the best frozen fruit drink in town. How could Simon conduct a survey with a sample that is representative of the population
Answer:
Step-by-step explanation:
The best way to do this would be to choose a random number of individuals that have bought a frozen fruit drink to survey. Then this same number of individuals should be surveyed in every single shop in the town. This would allow you to gather data from all of the shops and make sure that the sample is completely representative of the population as long as the individuals are chosen completely at random without introducing any external bias to the choice.
