Answers

Answer 1

Answer:

It will cost a total amount of $4.89 to rent a movie for 7 days

Word Problem

Given Data

Cost per day = $1.39

Fee per additional day = $0.50

Number of added days = 7

Let us find the mathematical expression for the above question

Total Cost = 1.39+ 0.5*7

Total cost = 1.39+ 3.5

Total cost = $4.89

Answer 2

Answer: Lets just simply solve:-

Days:- 1 2 3 4 5 6 7
1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = Cost to rent a movie for 7 days.

1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = 4.39

So, to rent a movie for 7 days it would cost $4.39.

Question :-

A cylinder has a diameter of 4 cm and a height of 8.2 cm. What is the surface area of the cylinder?

Answer :-

The surface area of the cylinder is 128.112 cm². Thus, the 2nd option, B makes it as the correct answer.

Diagram :-

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{2 \: cm}}\put(9,17.5){\sf{8.2 \: cm}}\end{picture}$

Solution :-

As per the provided information in the given question, we have been given that the diameter of the cylinder is 4 cm. Thus, the radius of the cylinder is 2 cm. The height of the cylinder is 8.2 cm. We have been asked to find or calculate the surface area of the cylinder.

To calculate the surface area of the cylinder, we will use the formula below :-

$\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_((Cylinder)) = 2\pi r^2 + 2\pi rh \:\:}}$

Substitute the given values into the above formula and solve for surfacearea:

$\sf:\implies Surface \: Area_((Cylinder)) = 2\pi r^2 + 2\pi rh$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(3.14)(2 \: cm)^2 + (2)(3.14)(2 \: cm)(8.2\:cm)$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(3.14)(4 \: cm^2) + (2)(3.14)(16.4\:cm^2)$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(12.56 \: cm^2) + (2)(51.496 \: cm^2)$

$\sf:\implies Surface \: Area_((Cylinder)) = 25.12 \: cm^2 + 102.992 \: cm^2$

$\sf:\implies \bf{Surface \: Area_((Cylinder)) = 128.112 \: cm^2}$

Therefore :-

The surface area of the cylinder is 128.112 cm². Thus, the 2ndoption, B makes it as the correctanswer.

the length of a rectangle is 5 less than 3 times the width. the perimeter is 150 centimeters. what is the length and width?

Answers

The lenght: x
The width: y
x = 3y-5 (cm)
x + y = 150/2 = 75 (cm)
=> 3y-5+y = 75
=> 4y = 80
=> y = 20 (cm)
=> x = 3×20-5 = 55 (cm)

Micheal was solving an equation and the last line of his work was 5=7.Which statement best describes the solution to the equation Micheal was solving?A. the solution is 5
B. The solution is 7
C. There equation has infinitely many solutions
D. There equation has no solution

P.S. There no equation to show you guys sorry.... :(

Answers

The equation has no solution.

For example, the equation could be

3x + 5 = 3x + 7

Subtract 3x
from each side: 5 = 7

No value of ' x ' can make 5 equal to 7,
so the equation has no solution.

D because in no way can 5=7

Emily's meal costs $32.75 and Darren's meal costs $39.88. Emily treats Darren by paying for both meals and leave a 14% tip. find the total cost

Answers

The best thing to do is to find the cost of the two meals then find the tip. $32.75+$39.88= $72.63
You've then got to find the 14% tip, you can either do this by finding 1% and then multiplying by 14. Or, you can divide the total answer by 100, and mutiply by 14.
$72.63/100= $0.73 (rounded) and then multiply this by 14, gives you $10.22
You've then got to add $72.63 to $10.22, and this gives you $82.85
Therefore, the total cost of the meal is $82.85
Hope this helps :)
