Answer:

Slope: 5

Y-Intercept: -7

Answer:

$37.20 per day

Step-by-step explanation:

Since $1.55 is the amount per pound you would multiply 1.55 x 24 to get 37.5 and since it is money you would add a zero at the end, it would look like so,

$37.20

Hope that helps and have a great day!

Answer:37.2

Step-by-step explanation:

so first you do 24 since its the pounds and since that's for a whole day so if you do a 24 times 1.55 which is 37.2 i hope this helps and can i get the brainiest

Step-by-step explanation:

53y+52=5 13−3x6=−16x+8=5

Answer:

The slope is -4, and the y-intercept is 1. The equation is y=-4x+1.

Step-by-step explanation:

To find slope use this equation:

(y2-y1)/(x2-x1)= slope (m)

And the y-intercept is b and you can find that just by looking at the graph.

Answer:

ad =4

Step-by-step explanation:

Answer:

1) The first filter to use is that if dealt between 5 people, there are 2 cards left over:

=> the number of cards must end in 2 or 7.

2) But if dealt between 4 people, 3 cards remain:

=> it is not possible for the number of cards to end in 2 as there cannot be a remainder of 3 with any even number, hence number must end in 7.

3) If the cards are dealt between 3 people to give n cards each, then 2 cards remain:

If 3n+remainder 2 ends in 7

=>3n ends in 5.

4) If 3n < 50 then the only possible numbers for 3n are 15 and 45.

We are told that a small number of cards are lost, so check 3n=45:

3n+ remainder 2= 47, and we are told that dealing between 4 leaves remainder 3:

47/4+= 11 remainder 3.

Hence the number of cards is 47.

the number of cards lost are 5 and the cards left are 47.

Step-by-step explanation:

We are given that certain number of cards are lost.

When divided among the four people, 3 cards are remaining. This implies that the number of cards lost may be 1,5 or 9 then only we will get the 3 cards left. Going by this approach, the number of cards available should be 52–1=51; 52–5=47; 52–9=43

Case 1: when one card is lost (available cards will be 51)

When 51 cards are divided among four people will give 3 remainders (48+3) which satisfies the given condition.

When 51 cards are divided among three people will give no remainder. But we expect the remainder to be 2. So, this case cannot be true.

Case 2: When 5 cards are lost (available cards will be 47)

When 47 cards are divided among four people will give 3 as remainder (44+3) which satisfies the given condition.

When 47 cards are divided among three people will give 2 as remainder (45+2) which satisfies the given condition.

When 47 cards are divided among five people will give 2 as remainder (45+2) which satisfies the given condition.

Answer:

Kevin's income is expected to be:

$8,880.

Step-by-step explanation:

Income from part-time job = $80 a week

For 36 weeks, he will earn $2,880 ($80 * 36)

Federal grants = $3,000 per semester

For semesters = $6,000 ($3,000 * 2)

Total income = income from part-time job plus the Federal grants

= $8,880 ($2,880 + $6,000)

The implication is that Kevin cannot spend above $8,880 towards his college education, unless he has another source of support during the year.  Otherwise, he may resort to borrowing, via college loans.

Answer:

Step-by-step explanation:

Compare your equation ...

  y = (-2/5)x +(-2)

to the slope-intercept form ...

  y = mx + b . . . . where m is the slope and b is the y-intercept.

Matching these patterns, you should be able to see that ...

  m = -2/5 = slope

  b = -2 = y-intercept

A family is saving up for a house payment. If they deposit $400 each month into an account that pays 4.8% interest compounded monthly how much money will they have in 8 years from now

The formula =

P = d( (1 + r/k)^nk - 1)/r/k

d = Amount deposited monthly = $400

r = interest rate = 4.8% = 0.048

k = compounding frequency = 12 months

n = number of years = 8

P = 400((1 + 0.048/12)^8 × 12 - 1)/0.048/12

P = (400 ( 1 + 0.004)^96 - 1)/0.004

P = (400 ( 1.4495569791 - 1)/0.004

P = 40(0.4495569791)/0.004

P = 179.82279162/0.004

P = 44955.697906

Approximately

P = 44,956

yan na yung answer sana maka tulong

Answer:

(3/14)

Step-by-step explanation:

(-1/2)/x = (-7/3)

(-1/2) = (-7/3)x

(-3/6) = (-14/6)x

(-3/6) = (-14/6)(3/14)

(-3/6) = (-42/84)

(-1/2) = (-1/2)

(-1/2)/x = (-7/3)

(-1/2)/(3/14) = (-7/3)

(-1/2) x (14/3) = (-7/3)

(-14/6) = (-7/3)

(-7/3) = (-7/3)

This question has no direct question, so here are some facts if you want them:

This equation can be expressed as a linear equation.

The equation can be expressed as: y =40x + 500

The y-intercept is 500, and the slope is 40.

If you type in a graphing website like desmos, then you can actually graph the line if you wanted (or needed) to.

I'm not really sure what the question is, but maybe if you needed help, here you go.

Answer:

1/4

Step-by-step explanation:

The fraction 1/2 of 1/2 is 1/4 so Darcy ingests 1/4 part of a candy bar.

The fraction is the division of the two numbers but the division is not wholly complete.

If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Amount of candy Darcy and Jordan have = 1/2

Amount of candy bar Darcy ate = 1/2 of 1/2

⇒ 1/2 (1/2) = 1/4

Hence "The fraction 1/2 of 1/2 is 1/4 so Darcy ingests 1/4 part of a candy bar".

One kilogram is equal to approximately 2.2 pounds.

To Find :

Which measurement is closest to the number of pounds that john lost.

Solution :

1 kg = 2.2 pounds .

Let, John lost x pounds.

x = 2.2 × 1.44 pounds

x = 3.168 pounds

Therefore, the number of pounds that john lost is 3.168 .

Hence, this is the required solution.

Average is determined by the sum of test scores divided by total number of tests. This can be represented in this equation:

95 + X / 2 = 92 ⇒ Multiply both sides by 2 to get of the divided by 2

95 + X /2 (2) = 92 (2)

95 + X = 184 ⇒ Subtract 95 from both sides to isolate x

95 -95 + X = 184 -95

X = 89

Therefore, they must get at least 89% to maintain an A.

Answer:

At this rate, 50 balloons will cost $37.50.

Answer:

No solution

Step-by-step explanation:

First we have to solve the equation;

10x + 28 - 3x = 7x + 38

Collect like terms;

7x + 28 = 7x + 38

Subtract 7x from both sides;

28 ≠ 38

No solution, because the number does not equal each other.
