Answer 1
On the table, x is in the left column, y is in the right.
Using the equation y = kx, we need to find k for that data
150 = k(1250)
150/1250 = k
0.12 = k

You can confirm that by doing the same with the second row, but I won’t put that here. It’s the same.

Dollars/kilowatt-hour is the label for the k of each equation (0.12, 0.15). We calculated dollars divided by (per) kWh.

Company P is less expensive than company M, because 0.12 < 0.15.

We need to buy 2,375 kWh of electricity from company P. The equation y = kx applies, where y is unknown, k = 0.12, and x = 2,375

y = (0.12)(2375)
y = $285

Let me know if you have any questions.

Step-by-step explanation:

Ronald’s parents have $35,000 saved and want to save a total of $125,000 for Ronald to go to college. Ronald’s parents began saving when Ronald was born and plan to save until he is 18 years old. Ronald is 5 years old now. About how much money do Ronald’s parents need to save each month?

Answers

Answer:

Money need to save each month  = $576.92 each month

Step-by-step explanation:

Given:

Amount of money need to save = $125,000 - $35,000 = $90,000

Number of year remain = 18 - 5 = 13 year

Number of months = 13 x 12 = 156 months

Find:

Money need to save each month

Computation:

Money need to save each month = 90,000 / 156

Money need to save each month  = $576.92 each month

Find two numbers whose sum is 8 and whose product is 17. Show all steps.

Answers

Answer:

See the solution below

Step-by-step explanation:

Find two numbers whose sum is 8 and whose product is 17. Show all steps.

Given data

Let the first number be x

and the second number be y

so

x+y= 8---------1

x*y= 17---------2

from 1

x= 8-y

put the value of x in 2

(8-y)*y= 17

8y-y^2= 17

collect like terms

y^2-8y+17= 0

Let us check the discriminant

y=  √b^2-4ac

y=   √-8^2-4*1*17

y= √64-4*1*17

y= √64-68

y= √-4

Hence the problem has no real solution because the discriminant is negative

Answers

Answer:

1) 27.374

2)9.177

Step-by-step explanation:

1) To get the value of x , we use the appropriate trigonometric ratio

From what we are given;

we have the hypotenuse ( the side facing the right angle) and the adjacent

The trigonometric identity to use here is the cos

The cos of an angle is the ratio of the adjacent to the hypotenuse

cos 64 = 12/x

x = 12/cos 64

x = 27.374

2) Here, we are given the hypotenuse and the opposite

The trigonometric ratio to use here is the sine

the sine of an angle is the ratio of the opposite to the hypotenuse

thus, we have it that;

sin 35 = x/16

x = 16 sin 35

x = 9.177

-2/8, -0.2, -3/7 from least to greatest???

Answers

Answer:

-3/7, -2/8, -0.2

Step-by-step explanation:

-0.2 = -1/5

We have -3/7, -2/8 and -1/5

For positive b and d:

a/b < c/d if and only if a*d < c*b

-3/7 < -2/8 if and only if -3*8 < -2*7; obviously true

-2/8 < -1/5 if and only if -2*5 < -1*8; -10 < -8; true

so we get -3/7 < -2/8 < -0.2

Solve the equation 17=5k-3

Answers

Answer:

k = 4

Step-by-step explanation:

17 = 5k - 3

+3.         +3

20/5 = 5k/5

4 = k

k = 4

Answer: k = 4

17=5k-3

1. In order to solve this linear equation, we'll need to group all the variable terms on one side, and all the constant terms on the other side of the equation. In the problem, term -3 will be moved on the left side. Notice the sign changes when you move it to the left.

17=5k-3 ⇒ 17 + 3 = (5k - 3) + 3

20 = 5k - 3 + 3

2. Add the numerical terms.

20 = 5k - (3 + 3) = 6. Note: We don't need the six in the 3rd step.

20 = 5k

3. Switch the variable term. (Ex: 3x + 9 ⇒ 9 + 3x)

20 = 5k ⇒ 5k = 20

5k = 20

4. We will need to isolate the variable, to do that, get rid of the coefficient that it multiples. We can do that by dividing 5 by both sides.

5k/5 ÷ 20/5 = 1k/4

5k/5

5. We'll need to reduce 5k/5 to its lowest terms. We can divide the factors that appear both in the numerator and denominator. If we look at 5k/5, 5 appears both in the numerator and denominator.

5k/5 ⇒ k = 2²· 5/5

6. Lastly, we can do the same thing as we did in the 5th step. That'll lead us to k = 2²

7. Solve for 2²

2 x 2 = 4.

Hence, our answer is 4.
