Answer 1

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.

If line m || line n and Ð2 measures 35°, what is the measure of Ð5?

Answers

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]

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

Answers

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]

part b: The probability for it ending open end up is 50/100. Same with open end down. For on its side, there is 25/100 probability.

part c: In 1000 tosses, I predict the cup will land 250 times on its side.

part d:If we tape a quarter to the bottom of the cup, it will most likely land up end up. This is because the quarter is weighting down the cup, causing it to land upwards.

If your answer is incorrect then you do not get brainly

Answers

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.

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%

Answers

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! :)

The percentage of people at the pool and in the water is a representation of the fraction of people in the water to the total people at the pool, written like this.

people in water / total people at the pool

Substituting the given numbers:

54 / (54 + 66)

54 / 120

Solve the fraction and multiply by 100 to find the percentage:

54 / 120 = 0.45 x 100 = 45%

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?

Answers

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.

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?

Answers

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.
