Step-by-step explanation:

I just kinda know I'm good with cups and gallons

Answer:

12kg

Step-by-step explanation:

the total money is =1500

each kg =25

so, we first multiply 25 as each kg by 5kg. To have the kg remaining

25×5 = 125

then

1500÷125

=12kg

he bought 12kg,

Answer:

Step 1) P = 600, Decimal format: 0.04, Balance = 624

Step 2) Principle = 624, Balance = 648.96

Step 3) Principle = 648.96, Balance = 674.92

Step-by-step explanation:

Use the formula of A = P(1 + r/n)^n*t

P = 600, r = 4%, n = 1, t = 1 years.

Plug in

A = 600(1 + 0.04/1)^1*1

A = 600 * 1.04^1

A = 600 * 1.04

A = 624

To find the seperate interest

A = P + I

624 = 600 + I

I = 624 - 600

I = 24

Repeat for Step 2

P = 624, r = 4%, n = 1, t = 1

A = 624(1 + 0.04/1)^1*1

A = 624 * 1.04^1

A = 624 * 1.04

A = 648.96

Repeat for interest

648.96 = 624 + I

I = 648.96 - 624

I = 24.96

Repeat for step 3

A = 648.96, r = 4%, n = 1, t = 1

A = 648.96(1 + 0.04/1)^1*1

A = 648.96 * 1.04^1

A = 648.96 * 1.04

A = 674.92

Interest repeat

674.92 = 648.96 + I

I = 674.92 - 648.96

I = 25.96

The time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.

The rule of 72 is the easy way to calculate the number of years required the investment with the given interest rate. It can be calculated as,

[tex]t\approx\dfrac{72}{r}[/tex]

Here, (t) is the time period and (r) is the rate of return.

The invested amount is $1500 and the value of APR is 8%. The time we have to calculate using the rule of 72.

The final amount of the investment is $3000 which is double the initial amount. Thus, the time period required to double the investment with 8% of interest is,

[tex]t\approx\dfrac{72}{8}\\t\approx9[/tex]

Thus, the time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.

The x value for the third quartile for this distribution is 106.8

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

where μ is the mean, x = raw score and σ is the standard deviation.

Given μ = 100, σ = 10.

The third quartile correspond with a z score of 0.675, hence:

0.675 = (x - 100) / 10

x = 106.8

Answer:

y = 2

Step-by-step explanation:

So we need to find the slope first.

m = y_2 - y_1/x_2 - x_1

Substitute

m = 2 - (2)/8 - (-3)

Simplify now.

Multiply -1 by 2

m = 2 - 2/(8 - (-3)

2 from 2

m = 0/8 - (-3)

Now we need to simplify the denominator.

To do so lets multiply -1 by -3

m = 0/8 + 3

m = 0/11

m = 0

Now we have the slope of 0 and the given point of (-3, 2)

So y - (2) = 0 * (x - (-3)) (Formula > y - y_1 = m(x - x_1) this comes from the original slope equation]

Simplify further

y - 2 = 0 * (x + 3)

Now we solve for y

Multiply 0 by x + 3

y - 2 = 0

Add 2 to both sides

y = 2

Answer:

-3,2 and 8,2

Step-by-step explanation:

Answer:

y=3x-10

Step-by-step explanation:

When you have to find a parallel line, you take the slope of the other line, so we already know y=3x+b. Then, plug in 2 and -4 as your x and y values and you get -4=3(2)+b. Then solve 3×2=6, so -4=6+b, subtract 6 from both sides, -10=b.

I THINK!!!!!! (x, y) = (-4, -25) im not completely sure tho

Step-by-step explanation:

substitute y = 7x + 3 in equation 2

9x - 2y = 14

9x - 2(7x + 3) = 14

9x - 14x + 6 = 14

-5x + 6 = 14

-5x = 14 - 6

x = 8 ÷ 5

x = 1.6

subs x = 1.6 into equation 1

y = 7x + 3

y = 7(1.6) + 3

y = 11.2 + 3

y = 14.2

thus, x = 1.6, y = 14.2

Answer:

513,000,000

Step-by-step explanation:

To write five hundred thirteen million in numbers change “five hundred thirteen million” to “513”, then multiply 513 by 106.

Alternatively, move the decimal point 6 places to the left:

513 × 106 = 513000000,

513 → 5,130 → 51,300 → 513,000 → 5,130,000 → 51,300,000 → 513,000,000.

Besides, five hundred thirteen million means:

Answer:

  a) y = 10x +500

  b) $500

  c) $15 for 100; $10.50 for 1000

Step-by-step explanation:

We assume the given "cost per unit" is the variable cost per unit. The total cost (y) for x units, given some fixed cost (b), is ...

  y = 10x +b

For 100 units, this is ...

  1500 = 10(100) +b

  500 = b . . . . . . . . subtract 1000

The cost function rule is ...

  y = 10x +500

__

The fixed cost is the cost of producing 0 units:

  y = 10(0) +500

  y = 500 . . . . . . . the fixed cost in dollars

__

The average cost (ac) of producing n units is the total cost divided by n:

  ac(n) = (10n +500)/n = 10 +500/n

The average cost for 100 units is

  ac(100) = 10 +500/100 = 15 . . . average dollar cost for 100 units

The average cost for 1000 units is ...

  ac(1000) = 10 +500/1000 = 10.50 . . . average dollar cost for 1000 units

Answer:

-6

Step-by-step explanation:

x-intercept is y = 0, so the point is (-6, 0), answer is -6

The Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).

The term "intercept" refers to the location where a line or curve crosses a graph's axis. The x-intercept is the point at which the x-axis is crossed. The y-intercept is the point at which the y-axis is crossed.

The x- or y-axis intersection point is what is meant when a line has an intercept. The y-axis is often taken into account if the axis is not stated. The letter "b" is typically used to represent it.

We know that the x intercept can be find where the value of y=0

So, From the table attached,

For x = -1, f(-1) = 0

For x = 2, f(2) = 0

For x = 3, f(3) = 0

Thus, Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).
