Answer:
40
Step-by-step explanation:
Two ways we can solve this problem:
1. Graphically
2. Mathematically
Because you already solved it graphically, I will show you how to do so mathematically. Of course, graphically is much much easier and more efficient in this problem.
Let's break the problem down.
First, we are given a graph which contains a slope.
To find slope, we use the technique -> rise/run
Picking 2 obvious points from the graph, we can see
1st point -> (10, 20)
2nd point -> (40, 80)
Now, let's find the slope
[tex]\frac{80-20}{40-10} = \frac{60}{30} = 2[/tex]
Now, we have an equation y = 2x, where y = number of pies and x = cups of sugar
We want to find how many cups of sugar we need to bake 80 pies. Simply substitute 80 = number of pies = y
y = 2x -> 80 = 2x
Solving for x, divide both sides by 2
40 = x
We need 40 cups of sugar.
Of all the people at a community swimming pool, 54 are in the water and 66 are not in the water. What percentage of the people at the pool are in the water?
10%
45%
82%
55%
Answer: 45%.
Step-by-step explanation: When you solve problems like these, you need to make the total 100%. The total amount of people at the community pool is 120. 120 can be our 100%. 66 people aren't in the water and 54 are in the water. As you can see, less than half of the total number of people at the community swimming pool is in the water, which means that is 45%. The 66 people who aren't in the water are 55% of the total people that are at the community swimming pool. So in summary, 45% of the total people who are in the community swimming pool are in the water.
Have a great day! :)

Answer:
x=-2
y=9
Step-by-step explanation:
Multiply one of the equations to get negative terms with equal y coefficients. Add them together then solve for x.
Substitute x in one of the equations then solve for y.
You can check your answer by substituting x and y into one equation and solving to obtain the same answer on the right side of the equation.

Answer:
<
Step-by-step explanation:
The reason why this is your answer is that because the two numbers are in Negatives, the higher the number closer to 0, the larger than it is to a number farther to zero on the left side of the number line.
so hence, your answer is <

Answer:
<
Step-by-step explanation:
-4 < -1
Note:
< → Less than
> → Greater than
= → Equal
Explain:
if you put -4 and -1 on a number line it on the left. But -4 is more on the left than -1. Thus, we can know that -4 is less than -1.

Calculate the snow load for the low-slop (flat) roof. For this structure, we will use the following coefficients. Cs = 1.0 Ce = 1.0 Ct = 1.0 Is = 1.1 Pg = 25
Answer:
The width of member is as follows:
b = 3 ft
b = 3 × 12 in.
b= 36 in.
The depth of member is as follows:
d = 8 ft
d = 8 × 12 in.
d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d
A= (36 - 7/8) × 96
[tex]A = 3372in^{2}[/tex]
Calculate the maximum axial tensile load by ASD method as follows:
P = f × A
P = 1000 x 3372
P = 3372000 lbs
P = 3372 kips

If line m || line n and Ð2 measures 35°, what is the measure of Ð5?
Answer:
145
Step-by-step explanation:
angle 2 = angle 3
=> angle 3 = 35
now, we have
=> 35+angle 5 = 180
=> angle 5 = 180 - 35
=> angle 5 = 145
Answer:
145°
Step-by-step explanation:
line m || line (Given)
[tex]m\angle 2 = 35\degree ......(1)[/tex] (Given)
[tex]m\angle 3 = m\angle 2 ......(2)[/tex] (vertical angles)
From equations (1) and (2)
[tex]\implies m\angle 3 = 35\degree[/tex]
[tex]m\angle 3 +m\angle 5 = 180\degree[/tex] (interior angles on the same side of transversal)
[tex] \implies 35\degree +m\angle 5 = 180\degree[/tex]
[tex] \implies m\angle 5 = 180\degree-35\degree[/tex]
[tex] \implies m\angle 5 = 145\degree[/tex]

Susan has two dogs named Murphy and Fido. She feeds each of them the same type of dog food. Murphy eats 2/3 of a can of dog food each day. Fido eats 1/2 of a can of dog food each day. Each can of dog food costs $1.75. The pet store is offering a sale that allows customers to buy one can of food and get one free. Susan wants to buy a 60-day supply of dog food during the sale. To the nearest cent, what would be the cost of Susan's dog food purchase before tax?
Answer:
$61.25
Step-by-step explanation:
The quantity for a 60-day supply is 60 times the 1-day usage. The BOGO offer means the sale price is effectively half the usual price.
__
One day supply: 2/3 can + 1/2 can = (4/6 +3/6) = 7/6 can
60-day supply: 60 × 7/6 can = 70 cans
Susan will be paying for 70/2 = 35 cans of dog food. (She will get 35 cans free.) So, her cost will be ...
35 × $1.75 = $61.25
The cost of Susan's dog food purchase would be $61.25 before tax.
You flip a coin and roll a dice. The resultant outcome table where H means heads, T means Tails, and the number represents what number was rolled on the dice. The outcome list is as follows
What is the probability that the coin reads heads or tails and the dices number is less than or equal to 6?
Answer:
hee-hee
Step-by-step explanation:
We first have to find out how many possible outcomes are in total.
There are 2 outcomes for the coin, either that the coin reads heads or tails.
There are 6 outcomes for the die, from 1 to 6.
2 x 6 = 12
There are 12 possible outcomes.
Now let's move on to the favorable outcomes.
We want to get the coin to flip on either heads or tails, and that the die has a number greater than or equal to 6.
The coin can only flip heads or tails.
The die's sides only goes up to 6.
The probability that the coin reads head and tails and that the dices number is less than or equal to 6 is 12/12 or 1. It is certain.

The stem-and-leaf plot lists the number of different ingredients found in different industrial cleaners. How many cleaners had more than 80 ingredients? Enter the answer in the box. cleaners
If your answer is incorrect then you do not get brainly
Answer:
Step-by-step explanation:
A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).
Since the key says 4|0= 40 the answer to your question is 12. Twelve cleaners have more than 80 ingredients.
Answer: 12.
Step-by-step explanation: According to the key, 4|0 means 40, which applies to any other stem and leaf on the chart. For example, on the chart, any numbers to the other side of the 8 are more than 0 which can be 8|2 or 8|5, so those count. 9|0 or 90, is way bigger than 80, so any numbers next to 90 count as well. I circled all the numbers that are correct, which is 12.

The original price of a truck is $30,100. There is a sale going on that offers 35% off. What is the total selling price of the truck?
A. $36,120
B. $31,605
C. $19,565
D. $10,535
Answer:
19,565
Step-by-step explanation:
35% of 30,100=10,535
subtract that by 30100
30100-10535=19565
quick mafss
Answer:
c
Step-by-step explanation:
original price=30100
35% off = 30100 * 35% = 30100 * 0.35 = 10535
10535 is the savings, so substract this from the original price to get new price
30100-10535= [19565]
