Angles X and Y are supplementary. Angle X is 3 times the measure of angle Y. What is the measure of angle X?
45°
60°
120°
135°
[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

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
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.

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.
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

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)
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-5
(please give explanation too)
The sum is a+1*(-5) since you have a multiplication with different signs (+ -).
Multiplication Sign RulesThe 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.

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]

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