(please give explanation too)

Answers

The sum is a+1*(-5)  since you have a multiplication with different signs (+ -).

Multiplication Sign Rules

The rules to multiplication of numbers are:

+  +  or  -   -

      The result presents a positive sign (+) because the signs are same.

+  - or   -   +

     The result presents a negative sign (-) because the signs are different.

The given function is a linear equation with one variable (a). You can rewrite the expression  a-5 as a sum. See below.

Iman had twice as much money as Daphne at first. After Iman had spent $128 of her money on a bag and Daphne had spent $40 of her money on a dress, they had an equal amount of money left. How much money did each of them have left? pls help me.​

Answers

Step-by-step explanation:

x = Iman's money

y = Daphne's money

x = 2y

x - 128 = y - 40

now we use the first equation as identity in the second equation and get

2y - 128 = y - 40

y - 128 = -40

y = $88

x = 2y = $176

these were the starting values.

now, after spending, they have both left

176 - 128 = 88 - 40 = $48

Write an equation describing the relationship of the given variables.

y =

Answers

Answer:

[tex]y = 2x^4[/tex]

Step-by-step explanation:

The given statement can be represented as:

[tex]y\ \alpha\ x^4[/tex]

[tex]x =3; y = 162[/tex]

Given

Represent this as an equation

[tex]y\ \alpha\ x^4[/tex]

Convert variation to equation

[tex]y = kx^4[/tex]

Where k is a constant of variation.

Substitute [tex]x =3; y = 162[/tex]

[tex]162 = k * 3^4[/tex]

[tex]162 = k * 81[/tex]

Solve for k

[tex]k = 162/81[/tex]

[tex]k =2[/tex]

To get the equation, we have:

[tex]y = kx^4[/tex]

Substitute 2 for k

[tex]y = 2x^4[/tex]

The equation describing the relationship of the given variables is [tex]y=\frac{81}{162}x^4[/tex]

If y varies directly to the fourth power of x, this can be expressed as:

[tex]y \alpha x^4\\y=kx^4\\[/tex]

Given that x = 3 and y = 162, the equation becomes;

[tex]162 = k(3^4)\\162 = 81k\\k=\frac{81}{162}[/tex]

Substitute the value of k into the expression above to have:

[tex]y=kx^4\\y=\frac{81}{162}x^4[/tex]

Hence the equation describing the relationship of the given variables is [tex]y=\frac{81}{162}x^4[/tex]

[tex]x + y = 90[/tex]

[tex]x = 3y[/tex]

[tex]3y + y = 90[/tex]

[tex]4y = 90[/tex]

[tex]y = 15[/tex]

[tex]x = 3(15) = 45[/tex]

Answer:

45 °

Step-by-step explanation:

Knowing that:

Supplementary Angle = 180 °

Angle x is 3 time the measure of angle y.

Solve:

Equation below:

x + y = 180

x = 3y

Substitute

3y + y =180

4y = 180

Divide both sides by 4

4y/4 = 180/4

y = 45

Value of x:

x = 3 × 45

x = 135

Therefore the measure of angle x is 135.

x = 45

y = 135

sale price: $66.30 percent of discount: 65%
find the regular price​

Answers

Answer:

$189.43

Step-by-step explanation:

P = regular price

65% as a decimal = [tex]\frac{65}{100}[/tex] = .65

Discount = .65

To get the amount of the discount we would multiply P * .65

To find the sale price we subtract the discount from the original price.

Now we write our equation:

P - P(.65) = $66.30  

Solve for P

P - P(.65) = $66.30  

1P - P(.65) = $66.30  

1P - .65P = $66.30  

.35P = 66.30   Divide each side by .35

.35P.35 = 66.30/.35

P = 66.30/.35

P ≈ $189.43

What formula to use for determining the probability that the mean stress level for a sample of 70 employees will fall above 52? (mean =50; STD 10)

Answers

Answer:

0.4207

Step-by-step explanation:

Determine z-score

[tex]z=\frac{\bar{x}-\mu}{\sigma/\sqrt{n}}\\ \\z=\frac{52-50}{10/\sqrt{70}}\\ \\z\approx1.6733[/tex]

Find P(Z>1.6733)

[tex]P(Z > 1.6733)=normalcdf(1.6733,\infty)\approx0.4207[/tex]

Therefore, the probability that the mean stress level for a sample of 70 employees will fall above 52 is 0.4207

A man won a lotto jackpot and he spent 2/5 of the money on luxury cars and 1/4 on buying a house. What fraction of his lotto earnings is remaining​

Answers

spent : 2/5 + 1/4 = 8/20 + 5/20 = 13/20

remains = 7/20

The 7/20th fraction of his lotto earnings is remaining.

Let us say the man has $100

Money spent on luxury cars = 2/5 of the money

Money spent on luxury cars = 2/5 * 100 = $40

Money spent on buying a house = 1/4 of the money

Money spent on buying a house = 1/4 * 100 =$25

Money left with the man = 100-40-25 = $35

$35 is what fraction of $100?

$35 is 35/100 fraction of $100.

35/100 = 7/20

So, the 7/20th fraction of his lotto earnings is remaining.

Hence, the 7/20th fraction of his lotto earnings is remaining.
