Abdul wants to rent a boat and spend at most $35. The boat costs $8 per hour, and Abdul has a discount coupon for $5 off. What are the possible numbers of hours Abdul coult rent the boat?
Use t for the number of hours, write your awnser as an inequality solved for t.
Answers
Answer:
Abdul can rent the boat for at most 5 hours.
Step-by-step explanation:
Let's call the number of hours Abdul rents the boat "t".
The cost of renting the boat without the discount coupon is $8 per hour, so the cost would be 8t dollars.
With the discount coupon, the cost of renting the boat would be 8t - 5 dollars.
We know that Abdul wants to spend at most $35, so we can write the inequality:
8t - 5 ≤ 35
Solving for t, we get:
8t ≤ 40
t ≤ 5
Therefore, Abdul can rent the boat for at most 5 hours.

(Surface Area of Cylinders MC)
Determine the exact surface area of the cylinder in terms of π.
cylinder with radius labeled 1 and one fourth centimeters and a height labeled 3 and three fourths centimeters
39 and one fourth times pi square centimeters
14 and one sixteenth times pi square centimeters
12 and one half times pi square centimeters
10 and 15 sixteenths times pi square centimeters
Answers
The surface area of a cylinder can be found by adding the areas of the top and bottom circles, as well as the area of the side (lateral) surface.
The radius of the cylinder is 1 and one fourth centimeters, which can be written as 5/4 cm. The height of the cylinder is 3 and three fourths centimeters, which can be written as 15/4 cm.
The area of each circle is πr^2, where r is the radius. So, the area of the top and bottom circles is:
2π(5/4)^2 = 25/2 π square centimeters
The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height. So, the lateral surface area of the cylinder is:
2π(5/4)(15/4) = 75/2 π square centimeters
Therefore, the total surface area of the cylinder is:
25/2 π + 75/2 π = 100/2 π = 50 π square centimeters
So, the exact surface area of the cylinder in terms of π is 50π square centimeters. None of the given options matches this answer.

Step-by-step explanation:
-6.1 in mixed number form is -6 1/10, making it greater than -6 4/9. This is because, if the numbers were positive, -6 4/9 would be greater than -6.1, but since the numbers are negative, it's opposite.
Therefore, the answer is:

A photo of a beetle in a science book is increased to 778% as large as the actual size. If the beetle is 15 mm, what is the size of the beetle in the photo
Answers
Answer:
Step-by-step explanation:
If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:
Size of beetle in photo = Actual size of beetle x 7.78
Substituting the given value of the actual size, we get:
Size of beetle in photo = 15 mm x 7.78
= 116.7 mm
Therefore, the size of the beetle in the photo is 116.7 mm.

You want to factor out the greatest common factor from ...
50x -6015x +6Greatest common factorThe greatest common factor is the largest expression that is a factor of both terms. Here, one term is a constant, so the GCF will be the largest constant that is a factor of both the coefficient and the constant.
For these numbers, your familiarity with multiplication tables will tell you the greatest common factors. More formally, you can find the GCF a couple of different ways.
FactoringYou can factor the numbers involved, and identify the set of common factors. The GCF will be the product of the numbers in that set:
50 = 2·5²; 60 = 2²·3·5; gcf = 2·5 = 1015 = 3·5; 6 = 2·3; gcf = 3Euclid's methodRepeatedly divide by the smaller of the two numbers or the remainder, until the remainder is 0. The last divisor is the GCF.
60/50 = 1r10; 50/10 = 5r0; gcf = 1015/6 = 2r3; 6/3 = 2r0; gcf = 3Factored formFactoring out the greatest common factor, we have ...

month. When will the amount of homeless pets surpass the amount of foster
homes available?

C) Approximate the solution(s). Why is this the approximate solution?
D) Using graph paper (and the table of values), sketch the situation to

Answers
Answer:
A) Let f(x) represent the number of foster homes available after x months, and let g(x) represent the number of homeless pets after x months.
f(x) = 20 + 2x (since 2 additional people are expected to foster each month)
g(x) = 10(1.15)^x (since the number of homeless pets is growing at a rate of 15% per month)

Write the following in slope intercept form:

Answers
Answer:
The equation y + 2 = 3/4x can be written in slope-intercept form by isolating the y-term and rearranging the equation. The slope-intercept form of the equation is y = 3/4x - 2
Answer:
y = 3/4x - 2
Step-by-step explanation:
The slope intercept formula y = mx + b
so y + 2 = 3/4x
=> y + 2 -2 = 3/4x - 2
=> y = 3/4x - 2
Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answers
74 meters
Step-by-step explanation:
The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.
2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.

How to find the equation of linear regression?To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.
The points for this problem are given as follows:
(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).
Inserting these points into a calculator, the equation is given as follows:
y = 1.05x - 10.43.
The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:
31 = 1.05x - 10.43
x = 41.43/1.05
x = 39.46.

What is $400 at 3% for 5 years?
A. Find interest earned
B. Find the balance of the account
Answers
The interest earned is $60 and the balance of the account is $460. The interest and the balance of the account will be both calculated with their given formulas.
An expense or payment for using borrowed money is interest; it is occasionally stated as a percentage of the principal borrowed. It could also be applied to the returns on investments or savings. Interest is the cost that a borrower typically reimburses a lender for the use of their funds.
A. We must use the formula-
Interest = Principal x Rate x Time, to calculate the interest earned.
Here, Interest = $400 divided by 0.03 and multiplied by 5.
Earned interest is $60.
B. We must utilize the formula-
Balance = Principal + Interest, to determine the account's balance.
Balance = $400 + computed interest in this instance.
Balance: $400 + $60.
The account's balance is $460.
