Answer: the answer is to divide and you will come up with the answer 1/12
Step-by-step explanation:
Answer:
-2 =y
Step-by-step explanation:
We can find the slope of the first line
m = (y2-y1)/(x2-x1)
= (2-8)/(-1-6)
= -6/-7
=6/7
Perpendicular lines have negative reciprocal slopes, so flip the slope and negate it
The perpendicular slope is -7/6
-7/6 = (y2-y1)/(x2-x1)
Put in the points
-7/6 = (y-5)/(5--1)
-7/6 = (y-5)/(5+1)
-7/6 = (y-5)/6
The numerators must be equal since the denominators are equal
-7 = y-5
Add 5 to each side
-7+5 = y-5+5
-2 =y
The amount of wrapping paper he use is 62.4 square inches
<h3>How to calculate the surface area of a prism</h3>
The formula for calculating the total surface area is expressed as:
Area = 4(area of triangle)
Find the area of the triangle
A = 0.5(6)(5.2)
A =3(5.2)
A = 15.6 square inches
TSA = 4(15.6)
TSA = 62.4 square inches
Hence the amount of wrapping paper he uses is 62.4 square inches

Answer:
20.25
Step-by-step explanation:
i think its asking for the long side
the pythagorean theorem states that in a right triangle a^2+b^2=c^2
a is 19
b is 7
c is the long side
19^2= 361
6^2= 49
361+49=410
410 =c^2
square root of 410 = ~20.25
Answer:
2 x 2 x 7
Step-by-step explanation:
if you want to get a number in it's prime factors, you will have to divide the number step by step until it gets to 1. How I got my answer is by writing 28 divide by 2 you will get 14 divide by 2 you will get 7 divide by 7. That how I got 2 x 2 x 7.
