5 = 2 + c
c = 3

Answer: y = 2x + 3

Perpendicular

m = - 1/2

(The slope is the inverse and negative for perpendicular lines)

The number of necklaces Lilly can make varies directly with the amount of time she spends making the necklaces. She can make 6 necklaces in ⅖ hour. How many necklaces can Lilly make in 5 hours?

Answers

Answer:

75

Step-by-step explanation:

Number of necklace= k × amount of time spent

6= k × 2/5

K = 6÷2/5

K= 6×5/2

K= 15

Therefore the number of necklace made in 5 hours can be calculated as follows

15 = number of necklace ÷ 5

Number of necklace = 15 ×5

Number of necklace = 75

Mr. Christian is giving away special candies for Halloween. He has decided to spend $75 on Halloween candies. Each bag of candied raisins costs
$2.25 and each bags of Snickers costs $3.50.
1. Write the equation that represents this situation. Be sure to include what your variables stand for.
2. If Mr. Christian decides to buy 10 bags of candied raisins, how many bags of Snickers did he buy?

Answers

Answer:

1. For the candied raisins, r can represent the candied raisins

r = $2.25

t can equal total

t = total

And for the snickers, s can represent them

s = $3.50

Our equation would be: r + s = t

2. $52.50

10 bags of candied raisins would cost $22.50 so then we would subtract $22.50 from $75.00 because Mr. Christian wants to spend his full amount. We would get $52.50 from subtracting which is the amount he spent on the Snickers!

I hope that this can help you

Answer:

1: 2.25r + 3.50s = 75 ( r = raisins and s = snickers )

2: 15

Step-by-step explanation:

If you are creating an equation, you need to know which parts of the question should be included. The parts included in this equation would be $75 (total amount of money spent on candy), $2.25 (cost of 1 bag of candied raisins ), and $3.50 (cost of 1 bag of snickers).In order to make the equation, you would need to multiply both 2.25 and 3.50 by the amount of bags bought, however we do not know that yet, so we use variables. I chose to use r to represent the bags of candied raisins bought, and s to represent the bags of snickers bought. So that would leave you with 2.25r + 3.50s. Now since 75 is the total amount of money spent, you would set 2.25r + 3.50s equal to 75.

The answer to number 2 is 15. If you were to substitute r for 15, the new equation would be 2.25(10) + 3.50s = 75. When you multiply 2.25(10), you get 22.50. you would then subtract that from 75, giving you 50.50. The equation is now 3.50s = 50.50. The next step is to divide 3.50 on both sides, which would result in just the variable on the left side, and 15 on the right side of the equals sign ( s = 15 )

Banks provide a number of services including all of the following except __________.

A. Payday Lending
B. Safety Deposit Boxes
C. Checking Assets
D. Cashier's Checks

Answers

Answer:

A. Payday Lending

Explanation:

Payday Lending is common for small lending companies and not banks. They assist clients who have a minimal amount of salary to borrow a small amount of money with a high interest. The amount of money he can borrow will depend on the amount of salary he receives per month. The client will not be required to give any form of collateral for the borrowed money, thus, the client is said to be high-risk. However, he will have to return the money over a short period of time with an interest rate that is high. Though it is easy to get a loan with this kind of service, you have to make sure that you are employed.

Banks prefer to offer loans to people who have a steady income and a certain amount of salary.

Answers

Answer:

[tex]Vanillas = \$5.6[/tex]

Step-by-step explanation:

Given

[tex]Cup\ Cakes = 24[/tex]

[tex]Cost = \$0.35[/tex] (each)

[tex]Vanilla = \frac{2}{3}[/tex]

[tex]Chocolate = \frac{1}{2}[/tex]

Required

Determine the cost of all vanilla cupcakes

First, we need to determine the number of vanilla cakes.

This is calculated by multiplying the fraction of Vanilla by number of cupcakes

So:

[tex]Vanilla = \frac{2}{3} * 24[/tex]

[tex]Vanilla = \frac{2 * 24}{3}[/tex]

[tex]Vanilla = \frac{48}{3}[/tex]

[tex]Vanilla = 16[/tex]

Since 1 cupcake costs $0.35.

16 would cost 16 * $0.35

So:

Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]

6. A farmer sows a certain crop. It costs $240,000 to buy the seed, prepare the ground, and sow the crop. In one year's time it will cost $93,200 to harvest the crop. If the crop will be worth $350,000, and the interest rate is 7%, what is the net present value (NPV) of this investment?

Answers

Answer:

$0

Step-by-step explanation:

Given that:

Preparation and sowing cost = $240,000

Cost of harvest after a year = $93,200

Worth of crop = $350,000

Interest rate (r) = 7% = 0.07

Net present value of Investment :

[(worth - Cost after 1 year) / (1 + r)] - initial investment cost

[(350,000 - 93,200) ÷ (1 + 0.07)] - 240,000

[256,800 / 1.07] - 240,000

$240,000 - $240,000

= $0

The vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards. So, option A is correct.

What is the Pythagoras theorem?

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

In order to find the length of a point to another point that has different y and x points, we will use the pythagorean theorem

(a^2 + b^2 = c^2)

Here, 16 and 11 are the distances from her house,

16^2 + 11^2 = c^2

c^2 = 377

c = 19.416...

Now, we have to convert this to yards;

19.416 x 10 = 194.16 yards

Hence, the vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards.

So, option A is correct.

Delilah and a group of friends had excellent service at a restaurant. They would like to give the server a 25 percent gratuity on their $140 bill.

Answers

Answer:

Here we want to calculate the 25% of $140.

Well, first we assume that:

$140 = 100%.

Now, assuming that, we can write the equation:

X = 25%

Where X is the 25% of $140.

Then we have the equations:

$140 = 100%

X = 25%

Let's take the quotient between these equations:

$140/X = (100%/25%)

Now let's solve this for X:

X = (25%/100%)*$140 = 0.25*$140 = $35

Then the tip will be of $35

35

you have to split 140 into 4 parts which is division

your  expression would be 140 divided by 4
