what is the answer to 3?
Answer:
Step-by-step explanation:
First, you have to find the perimeter of the base. You do that by adding all the sides,
There are two sides that are 13 mm and two sides that are 6 mm
13 + 13 is 26
6 + 6 is 12
26 + 12 is 38
Now you have the perimeter. Now you have to multiply is by the highest
So 38*14 (532)

Analysing a company's fundamentals will tell you a stock's intrinsic value, as opposed to the value at which it is being traded.

PLEASE PLEASE HELP ME!! I AM IN TESPARATE NEED OF HELP!!! PLEASE I AM BEGGING AT THIS POINT!!
Answer:
a) 13/10
b) [tex]y+15=\dfrac{13}{10}(x-5)[/tex]
c) [tex]y+2=\dfrac{13}{10}(x-15)[/tex]
d) Both equations are [tex]y=\dfrac{13}{10}x-\dfrac{43}{2}[/tex] so represent the same line
e) [tex]-\dfrac{43}{2}[/tex] °F ⇒ y-intercept
Step-by-step explanation:
a) Choose two ordered pairs from the table: (5, -15) and (15, -2)
Let [tex](x_1,y_1)[/tex] = (5, -15)
Let [tex](x_2,y_2)[/tex] = (15, -2)
Use the slope formula to find slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\implies m=\dfrac{-2+15}{15-5}=\dfrac{13}{10}[/tex]
b) Use point-slope with (5, -15)
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y+15=\dfrac{13}{10}(x-5)[/tex]
c) Use point-slope with (15, -2)
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y+2=\dfrac{13}{10}(x-15)[/tex]
d)
[tex]\implies y+15=\dfrac{13}{10}(x-5)[/tex]
[tex]\implies y=\dfrac{13}{10}x-\dfrac{43}{2}[/tex]
[tex]\implies y+2=\dfrac{13}{10}(x-15)[/tex]
[tex]\implies y=\dfrac{13}{10}x-\dfrac{43}{2}[/tex]
Therefore, they represent the same line
e) when x = 0:
[tex]y=\dfrac{13}{10}(0)-\dfrac{43}{2}=-\dfrac{43}{2}[/tex] °F
Represents the y-intercept on the graph

An animal shelter has 10 cats. Each day 20 cans of food are noworo
used for the cats. If each cat eats the same amount of food,
how many cans of food does each cat eat in a day?
Answer:
[tex]\huge\boxed{\bf\:\boxed{\mathfrak{2}}\:cans\:each}[/tex]
Step-by-step explanation:
We need to find the number of cans of food each cat in the animal shelter gets per day.
Given,
Total number of cats in the animal shelter = 10Total number of cans used = 20So,
Number of cans for each cat:
= Total number of cans / Total number of cats
= 20/10
= 2 cans each

vincent sells potatoes. He doesn’t sell potatoes my weight or one at a time. he insists on selling them in pairs.his customer graham wants a potato that weighs exactly 200g. Vincent tells him I only have 3 potatoes left. HERe they are A,B and C. A and B together weigh 300g, A and C together weigh 500g, B and C together weigh 400g. You can have any pair of them. Which if any of the potatoes weighs 200g? Which pair of potatoes should graham buy?
By solving a system of equations we will see that the best pair to buy is A and C.
Finding the equations:Here we have 3 potatoes, A, B, and C. Let's use these variables to define the weight of each potato.
Then, from the given information, we know that:
A + C = 500g
B + C = 400g
A + B = 300g
Then we have a system of equations, to solve it, first we isolate one of the variables in one of the equations. I will isolate A on the first one:
A + C = 500g
A = 500g - C
Now we can replace that in the third equation, now we have:
B + C = 400g
500g - C + B = 300g
Now we do the same thing, this time I will isolate C.
C = 400g - B
Let's replace this on the other equation:
500g - (400g - B) + B = 300g
500g - 400g + 2*B = 300g
100g + 2*B = 300g
B = (300g - 100g)/2 = 100g
So potato B weighs 100g.
We can use that to find the weight of the other two:
C = 400g - B = 400g - 100g = 300g
A = 500g - 300g = 200g
What pair should Graham buy?He wants 200g of potato, so he should buy one pair that includes potato A, which weight exactly 200g. And to get the most of his money, he should buy the pair that contains potato A and that weighs more. So the best pair will be A and C.

A store manager was trying to figure out how many people did their shopping online compared to doing it in stores. To do this she polled several houses in the nearby neighborhoods. The results are shown below:
Based on the information presented can you infer anything about the number of people who did their shopping online vs. in-store?
Based off of this information, it looks like there are more online shoppers than in-store shoppers, more simply because there are 4 arrays that have more online shoppers than in-store shoppers, and 3 arrays that have more in-store shoppers than online shoppers, and 1 array that has an even amount of shoppers. But if you add up the numbers for a total of 160/161, you see there are more in-store shoppers than online shoppers.
So there are more in-store shoppers total.

A triangle has angle measurements of 13°, 104°, and 63°. What kind of triangle is it?
Answer:
Obtuse
Step-by-step explanation:
Has angle >90.
Answer:
Obtuse
Step-by-step explanation:
An acute triangle has three angles that each measure less than 90 degrees. An equilateral triangle is a triangle in which all three sides are the same length. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.
Since the largest angle is 104 and is larger than 90 it is an obtuse triangle
