Answer:
(a)
let m represents renting movie and c represents the total cost of buying a rental card.
As per the given statement: A video store charges $10 for a rental card plus $2 per movie.
⇒ c(m) = 2m + 10 ......[1]
which implies that this equation represents the slope intercept form(i.e y = ax+b) where 2 is the slope and a y-intercepts of 10.
(b)
Graph of the given equation:
c(m) = 2m + 10
you can see in the figure given below.
(c)
now, to find the cost of buying a rental card and renting 6 movies.
⇒ m = 6 [ as m represents renting movie]
Substitute this m =6 in equation [1];
c(6) = 2(6) + 10
c(6) = 12 + 10
c(6) = 22.
Therefore, the total cost of buying a rental card and renting 6 movies is, $22.

Points A and B are 200 mi apart. A cyclist started from point A and a motorcyclist started from point B, moving towards each other.The speed of the cyclist was 17 mph, the speed of motorcyclist was 83 mph. At what distance from point A will they meet?
Answers
Answer:
D from A = 34 miles
Step-by-step explanation:
We know the total distance is 200 miles (this would be when they meet)
The rate for cyclist A is 17
The rate for cyclist B is 83
We know the time is equal
Distance = rate * time
Distance for A = 17t
Distance for B = 83 t
The total distance = distance for A + distance for B
200 = 17t + 83t
Combine like terms
200 = 100t
Divide each side by t
200/100 = 100t/100
They will meet at t =2 hours
I know you say we need the distance
Distance for A
D = 17*t
We now know t
D = 17*2
D = 34 miles
Answer:
Step-by-step explanation:
cyclist going 17 mph n motorcyclist going 83 mph opposite way
so their net closing speed=17+83=100mph
A n B 200 mi apart
so they will meet in 200/100=2hrs
at dat time, cyclist will be 2x17=34mi from pt A

Answers
Answer:
The rover would travel 75.95 centimeters in 15 1/2 seconds.
Step-by-step explanation:
Simply multiply 4.9 by 15 1/2.
Hope it helps!
Answer:
75.95 cm
Step-by-step explanation:
We know that distance = rate times time
d =rt
We know the rate = 4.9 cm/s
and time = 15 1/2 s = 15.5 s
Substituting these into d=rt
d = (4.9 cm/s) * 15.5 s = 75.95 cm
In a shipment if 1,000 bulbs 1/40 of bulbs were defective.How many bulbs were Not defective
Answers
Answer:
975 bulbs
Step-by-step explanation:
1/40 bulbs were defective
That means 1-1/40 were not defective
40/40 - 1/40 = 39/40 were not defective

Multiply the number of bulbs by the fraction that is not defective to get the number of bulbs that should not be defective.
1000 * 39/40 = 975 bulbs
You invest 23,400 annual interest rate of 4% compounded annually for seven years what is the balance of the account at the end of that time
Answers
Answer: 30792.80
=====================================
Work Shown:
We deposit P = 23400 dollars for t = 7 years, which is compounded n = 1 times per year at an interest rate of r = 4% = 0.04 (we'll use the decimal form of the interest rate)
So this means...
A = P*(1+r/n)^(n*t)
A = 23400*(1+0.04/1)^(1*7)
A = 23400*(1+0.04)^(7)
A = 23400*(1.04)^(7)
A = 23400*1.31593177923584
A = 30792.8036341187
A = 30792.80

if the ratio of 7 less than a number and 7 more than the number 2, what is the number?
Answers
Answer:
Step-by-step explanation:
I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".
Let x be the number.
Ratio is division.
(x-7)/(x+7)=2
Multiply by (x+7) on each side:

The bank charged Travis a $20 fee because his balance dropped below $0. He knows that he currently had an outstanding charge for $7.85 that he had not recorded yet. How much money will Travis have to deposit into his account so that the outstanding charge does not create another bank fee
Answers
Final answer:
Travis must deposit $27.85 to cover the $7.85 outstanding charge and the previous $20 overdraft fee, to avoid further overdraft fees and bring his account balance back to at least $0.
Explanation:
Travis needs to not only cover the outstanding charge to avoid further overdraft fees but also bring his account balance back to at least $0. If Travis currently has an outstanding charge of $7.85, and overdraft fees are typically $35 or higher, it's clear that merely covering the charge won't be enough; he must also compensate for any negative balance incurred from previous overdraft fees.
Assuming the $20 fee has already been applied to his account and his balance is now at -$20 (not considering any other transactions that have taken place), Travis would need to deposit enough money to cover both the fee and the outstanding charge. Therefore, he would need to deposit a total of $20 (to bring his balance to $0) plus the $7.85 outstanding charge, which sums up to $27.85. By depositing this amount, Travis would avoid a second overdraft fee and any additional monetary penalties.
It is worth noting that financial literacy is essential to manage personal finances effectively and avoid potential overdraft situations which could lead to a cycle of fees and negative balances.
In the first week students at RSM solved 25 percent of their monthly quota of problems. In the second week, they solved 110 percent of the number of problems solved in the first week. In the third week they solved 60 percent of the number of problems they had solved in the first two weeks and, in the fourth week, they solved the remaining 320 problems. How many problems did students solve in the four-week month?
Answers
Answer:
The number of problems solved = 2000
Step-by-step explanation:
Let us assume the monthly quota of problems be x
number of problem solved in first week = 25 % of x =[tex]0.25x[/tex]
number of problems solved in 2nd week = 110% of (problems solved in 1st week)
= [tex]1.10 (0.25x)[/tex]
=[tex]0.275x[/tex]
number of problem solved 3rd week= 60% of ( problems solved in 1st and 2nd week)
= [tex]0.60(0.25x+0.275x)[/tex]
=[tex]0.60(0.525x)[/tex]
=[tex]0.315x[/tex]
number of problem solved in 4th week = [tex]320[/tex]
now we have
number of problems solved in ll 4 weeks = x
[tex]0.25x +0.275x+0.315x+320=x[/tex]
[tex]0.84x+320=x[/tex]
[tex]320=x-0.84x[/tex]
[tex]320=0.16 x[/tex]
[tex]x=\frac{320}{0.16}[/tex]
[tex]x=2000[/tex]
Hence the number of problems solved = 2000
Final answer:
In the third week they solved 60% of the number of problems they had solved in the first two weeks and, in the fourth week, they solved the remaining 320 problems. The total number of problems solved in the four-week month is 492.
Explanation:
To solve this problem, we need to find the number of problems solved in each week and then add them together to get the total number of problems solved in the four-week month.
In the first week, the students solved 25% of their monthly quota of problems. Let's say their monthly quota is 'x'. So, they solved 0.25x problems in the first week.
In the second week, they solved 110% of the number of problems solved in the first week. That means they solved 1.1 * 0.25x = 0.275x problems in the second week.
In the third week, they solved 60% of the number of problems they had solved in the first two weeks. So, they solved 0.6 * (0.25x + 0.275x) = 0.345x problems in the third week.
In the fourth week, they solved the remaining 320 problems. This means the total number of problems solved in the first three weeks is 0.345x, and we can set up the following equation to find x: 0.345x + 320 = x.
Solving this equation, we get x = 491.429. Since we can't have a fractional number of problems, we can round x up to 492. Therefore, the students solved a total of 492 problems in the four-week month.

4)parallelogram
How determine if a quadrilateral is a parallelogramTo classify a shape as a parallelogram, the following four conditions must be satisfied
1. Opposite sides are equal in length.
2. Opposite angles are equal.
3. Consecutive angles are supplementary
4. Diagonals bisect each other.
Each of these conditions contributes to the definition of a parallelogram, and all of them must be satisfied for a shape to be considered a parallelogram.
From the figures
1) Not necessarily a parallelogram
The opposite sides are not equal.
GH is congruent to Gl and HJ is congruent to IJ. These are adjacent sides instead of opposite sides equality.
2) Given
RS is parallel to TU
SU is parallel to R(Converse of the Opposite Sides Are Congruent (OSAC) Theorem)
Since the both pairs of opposite sides of the quadrilateral are congruent, then the quadrilateral is a parallelogram.
3) Given PQRS
PQ||RS(given)
PR||QS(Converse of the Opposite Sides Are Congruent (OSAC) Theorem)
Since the both pairs of opposite sides of the quadrilateral are congruent, then the quadrilateral is a parallelogram.
4) <ABC ≅ DCB(alternate angles, AB||CD BC is transversal)
<ACB ≅ DBC(alternate angles,AC||BD,BC is transversal)
Therefore
Opposite angles are equal.
Pairs of opposite sides are parallel.
Adjacent angles are supplementary.
so, the quadrilateral is a parallelogram.

The formula for converting Celsius temperatures to Fahrenheit temperatures is a linear equation. Water freezes at 0 °C, or 32 °F, and it boils at 100 °C, or 212 °F. Find the slope and y-intercept for a graph that gives degrees Celsius on the horizontal axis and degrees Fahrenheit on the vertical axis. Then write an equation in slope-intercept form that converts degrees Celsius into degrees Fahrenheit.
Answers
The equation for converting a Celsius temperature into a Fahrenheit one is given by the linear equation F = 1.8C + 32. The slope of this equation is 1.8 and the y-intercept is 32.
Explanation:
The subject of this question is Mathematics, specifically the study of linear equations. To find the slope and the y-intercept of the equation that transforms a Celsius temperature into a Fahrenheit one, we can use the two points you provided: (0, 32) and (100, 212). The slope can be calculated as follow: (212 - 32) ÷ (100 - 0) = 180 ÷ 100 = 1.8. The y-intercept is the Fahrenheit temperature when the Celsius temperature is zero, so it's 32. Therefore, the equation you are looking for in slope-intercept form is: F = 1.8C + 32, where F is the temperature in Fahrenheit and C is the temperature in Celsius.
