Which of the following is the equation of the line that is perpendicular to
stiv31 [10]

When a line is perpendicular to another line with a given slope, you can use the given slope of the original line to find the slope of the perpendicular line. All you need to do is flip the reciprocals. Since the slope of the given line is -1/8x, the slope of the perpendicular line would be 8x. Since there is only one line with a slope of 8x in the answer choices, your answer would be:

a. y=8x+13

Hope this helps!

The owner of a toy store received a shipment of 1,552 party favors. The party favors came in 28 boxes. The same number of party
Svetradugi [14.3K]

let 


x = the number of party favors in each of the 27 boxes

y = the number of party favors in the last box


the total number of party favors is 1,552


27x + y = 1,552


since 1552 = 57*27 + 13


if we assume that y<x we conclude that there are 57 party favors in each of the 27 boxes and 13 party favors in the last box.

The area of an artist square canvas can hold 113 square square inches of paint. What is the approximate length of one side of th
Pavel [41]

Answer:

The approximate length of one side of the canvas (approximate to the nearest hundredth inch)= 10.63

Step-by-step explanation:

There are two ways to solve this problem . One is the use of the calculator and the other is the use of the fraction.

Now the square has equal sides length = breadth .

So we can simply find the length on one side by taking square root with the help of the calculator .

So when you press the symbol of square root after entering the number 113 we get the answer 10.63

Square = Length * breadth

Square = Length * length

Square = L²

One side =√ L²= L so √113= 10.63

The approximate length of one side of the canvas (approximate to the nearest hundredth inch)= 10.63
