Answers

Answer 1

Answer:

Answer:

$14

Step-by-step explanation:

x/17.5=20/100, do the butterfly method

17.5x20=350

350/100= 3.5

17.5-3.5=14

Answer 2

Answer:

Answer:14.00

Step-by-step explanation:

17.50*80/100 = 14.00

Find the equation of the line that passes through the midpoint of the line segment between P1(2, 4) and P2(−4, 2) and has slope 7. Let y be the dependent variable and let x be the independent variable.

Answers

The midpoint of the points is the average of the x-coordinate and y-coordinate. So in this case, the midpoint would be (-1, 3). So equations can be written in the form y=mx+b. Since the slope is 7, the m value is also 7. Substituting the point (-1, 3) as x and y makes the equation 3=7(-1)+b. So after isolating the b, the value of b is not 10. So the final equation is y=7x+10

-13=7d+64 what is the answer

Answers

Step 1: move 64 to a left side, -13 - 64 = 7d

Step 2: -77 = 7d

Step 3: $(-77)/(7)$ = d

Step 4: d = -11

it is d=11
because u subtract the negative 64 with a positive for a positive and negative turn 0 then u got to do the same side with -13-(-64)=7d then u add -13+-64=77 after u done that it will be 77=7d divide it by 7 on both side then u get d=11

A common rule is that housing expenses plus other debt payments should not be more than 36% of your monthly income. Your monthly income is $4,300, and you have student loan payments of $321 per month. How much can you spend on housing?

Answers

Answer:

We can spend $1,227 on housing.

Step-by-step explanation:

Given: A common rule is that housing expenses plus other debt payments should not be more than 36% of your monthly income.

Your monthly income is $4,300.

It means we can spend 36% of $4,300 on housing and other debts.

So 36% of $4,300 = 0.36 times $4,300 = $1,548.

So we can spend $1,548 on housing and other debts. It says you have student loan payments of $321 per month.

Housing expenses = $1,548 - $321 = $1,227.

Hence, we can spend $1,227 on housing.

Common rule of your salary
=> housing expenses + other debt payment should not be more than 36% of you monthly income.
=> 4 300 dollars is you monthly income.
Let's solve the 36% of it
=> 4300 * .36 = 1548
=> 1548 - 321 for you student loan = 1227 dollars - the housing expenses.

A spinner and 6 cards are shown below: A spinner with 3 equal sectors is shown in the figure. The colors Green, Blue, and Red are marked on it. The arrow points at the green color. Six cards are shown on the right side. The colors Purple, Green, Red, Yellow, Blue, and Pink are marked on them. Jordan spins the spinner and picks up a card without looking. What is the probability that the spinner stops at green and a yellow card is selected? 1 over 36 1 over 18 1 over 6 1 over 3

Answers

This is a case of joint probability: you want to know what the odds are of this event AND that event occurring. For a joint probability, the formula is usually given as:

P(A and B)=P(A)*P(B)

where P(A) is the probability of event A happening, P(B) is the probability of event B happening, and P(A and B) is the probability of both happening.

For this problem, let's say that event A is the probability that the spinner stops at the green color. Since the spinner has 3 colors and they have equal area (sector) occupied in the circle, each color has the same chance, 1/3 chance of being picked. Thus, there's a 1/3 chance of the spinner stopping at the green color so P(A)=1/3.

Event B is the probability of Jordan picking up the yellow card. There are six possible colors to pick and since Jordan picked up the card without peeking, each color has an equal chance to be picked. Thus, there's a 1/6 chance that the yellow card will be selected so P(B)=1/6.

Using the formula, we can then calculate P(A and B), the probability that the spinner stops at green and a yellow card is selected:

P(A and B)=P(A)*P(B)=1/3*1/6=1/18

Answer: the answer is 1/18, got it right on the test

Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 4 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups
