Answers

Answer 1

Answer: The total surface area is 633.9

Step-by-step explanation:

12.25 times 15.75, then divide by 2 = 96.46875 (this is the area of the triangle

Then times 4 = 385.875 (Because there are four triangles

15.75 times 15.75 = 248.0625 (The area of the square)

The sum is 633.9375

Rounded = 633.9

identify the slope and y-intercept of the function y= -5x+4

Answers

Answer:

The slope is -5 and the y intercept is (0,4). (D).

Step-by-step explanation:

The formula for this is y=mx+b. With m equaling the slope, and b equaling the y intercept. In the place of m, there is -5, getting you your slope of -5 and in the place of b there is 4 (meaning the coordinate (0,4)), getting you your answer. I hope this helps! :)

Answer: D

The answer to your question is 44.

can someone explain how to do this, I don't want the answer?

Answers

The table is filled out by following these steps:

Step 1) Pick any number you want for x. Usually small values work such as x = 0, but you can choose anything you want. Be sure it fits within the window of the graph.Step 2) Replace x with that number you picked. If you picked x = 0, then y = (1/3)x becomes y = (1/3)*0 = 0. Meaning x = 0 leads to y = 0. The point (0,0) is on the graph.Step 3) Go back to step 1 and repeat the process with other x values. I recommend picking multiples of 3 so you can avoid fractional values of y.

Follow those steps listed above so you can fill out the table. Each row of the table generates a different (x,y) point on the graph. Then draw a line or curve through the points. In this case, it's a straight line.

This straight line has a slope of 1/3 because y = (1/3)x is in slope-intercept form y = mx+b where,

m = 1/3 = slopeb = 0 = y intercept

A slope of 1/3 means "go up 1, over to the right 3" when hopping from point to point along the line.

The unit rate and slope are the same thing when it comes to linear equations.

You have the slope already, you need to find the unit rate with the slope, you just have to put 1/3 in the graph and use rise/run

Find the volume of the cone. Round to two decimal places

Answers

Answer:

564.44

11*7 squared                    

Answer:

V = 564.15 ft^3

Step-by-step explanation:

The formula for the volume of a cone of base radius r and height h is

V = (1/3)(pi)(r^2)(h).  Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is

V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3

Answers

Answer:

The best buy item is the Frito-Lay mi Variety Pack. Going for only 0.35 per item.

Step-by-step explanation:

All I did was the equations and then I compared the answer, the lowest answer is the best buy since it is the lowest price found.

Frito-Lay:

9.88/28 = 0.35

Unit rate is 35 cents

Pringles:

6.48/18 = 0.36

Unit rate is 36 cents
Pack of 18:

11.21/18 = 0.6

Unit rate is 60 cents

Pack of 24:

15.85/24 = 0.66

Unit rate is 66 cents

GC:

14.75/30 = 0.49

Unit rate is 49 cents

Sweet Treats:

10.75/25 = 0.43

Unit rate is 43 cents

Comparing all of this data, it can easily be seen that the Frito-Lay mi Variety Pack is the best deal you can find out of these 6 deals.

The amount of sports drink in a cooler during practice is modeled by the equation y = 648 -24x

y = the number of ounces in the cooler after practice
x = the number of players at practice who take drinks from the cooler

What does the Y-INTERCEPT mean?

Answers

When x is 0 what’s the y , is that what u r asking
The answer would be C. Because it is asking what the Y intercept means. They tell us y= the number of ounces in the cooler after practice. We do not know how much the kids drank, but they do tell us X=the number of players who take drinks from the cooler. Since the question is 24X we can assume the 24 means the amount the students drank. If we solved that, we would know how much was left after practice which is what Y is asking us. So the answer is C because it tells us what the Y intercept means (Each person drank approximately 24 OZ of water at the practice. 648-24x)

Hope this helps!

12 square units

Step-by-step explanation:

The answer might be a little easier to see if we slide that triangle on the left over to turn this shape into a rectangle! This is a technique you can apply to any parallelogram. Looking at the newly constructed rectangle, we can find its area by multiplying its length (2) and width (6) for an area of 2 · 6 = 12 square units.

Answer:

12 units squared

Step-by-step explanation:

Formula for area of a parallelogram:

A = b • h

The base of the parallelogram is 6 units. The height of the parallelogram is 2 units. Multiply the two numbers together. 6 • 2 = 12 units squared.

A map of a town has no scale. You know that the distance between the post office and the park is 2 mi. On the map it is 2 in. Also, on the map you know the distance from the park to the school is 8 in. What is the actual distance in miles between the park and the school?
A. 0.5 mi.
B. 4 mi.
C. 8 mi.
D. 16 mi.

Answers

The answer is C

If you are given a 2 inch distance from the post office to the park and it’s known that 2 inches= 2 miles and you also know that the distance from the park to the school is 8 inches which is 4 times more than the distance from the post office to the park then you know that the amount of miles will be 4 times more than 2 miles so, 4x2=8 which means that the distance between the park and school is 8 miles.

Hope that makes sense :))
It’s eight miles, as you can see 2 miles = 2 inches which means every inch is one mile, so eight inches means eight miles! Hope this helps.

A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.

Answers

Answer:

75 total tickets

Step-by-step explanation:

METHOD 1:

We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.

So, basically, we solve for x:

We have, 60% × x = 45

or, 60/100 × x = 45

Multiplying both sides by 100 and dividing both sides by 60,

we have x = 45 × 100/60

x = 75

If using calculator, enter 45x100/60, which will give you the answer.

------------------------

METHOD 2:

Division is the opposite of multiplication

Start with the formula to calculate the percentage of total

y=value÷ percentage/100

Substitute values in the equation

y=45÷60/100

Simplify and solve

y=45÷0.6

y=75

Both methods give you 75, therefore 75 tickets have been sold

So your supposed to do 1.50/1 x 60% which is 90
