Step-by-step explanation:
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
find the value of x

Step-by-step explanation:
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.

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

Answer:
50° for angle FEG
Step-by-step explanation:
Following the Verticle Angles Theorem, the angle on the other side of 140 must also be 140. Since it is split up and we know one of them is a right angle, we must subtract 90 from 140.
140 - 90 = 50.
Thus, angle FEG is 50°.

Answer:
a) x=-a, x=a+b
b) x=5/2a, x=1/3b
c) x=1/2a, x=a/a-2
Step-by-step explanation:
a) (x-a)(x-a)-b(x+a)=0
(x+a)(x-a-b)=0
x=-a, x=a+b
b) 3x(2x-5a)-b(2x-5a)=0
(2x-5a)(3x-b)=0
x=5/2a, x=1/3b
c) (2a-4)x^2=a^2(x-1)
(2x-a)(ax-2x-a)=0
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

Please help 50 points: A ball is thrown straight up, from 3 m above the ground, with a velocity of 14m/s. When does it hit the ground? Use vertical motion formula.
Answer:
3.058s
Step-by-step explanation:
i cant rewrite everything i solve in the paper sorry
Step-by-step explanation:
In this question, to find the total height first, we must also take into consideration the acceleration due to gravity as well. To find the distance by which acceleration due to gravity pulls the ball down must know the Initial velocity.
In the answer key, it says that gravity changes the ball's height by a distance of -5t^2
Is initial velocity in this question 0 or 14m/s? Because if it is 14, then gravity should change the balls position by -(14+5t^2), not -5t^2, because if I remember correctly, the formula for finding distance is vt(initial velocity)+(1/2)at^2 ,and not just (1/2)at^2

scott wants to rent a boat and spend at most $79. The boat costs 8 per hour, and Scott has a discount coupon for $9 off. What are the possible numbers of hours Scott could rent the boat?
Answer:
11 hours
Step-by-step explanation:
Using the $79 dollars, Scott can get up to 9 hours with the boat. Scott will be left with $7, adding the $7 to the $9 coupon, Scott will then have $16 which can give Scott an additional 2 hours summing the total hours up to 11 hours Scott can rent the boat for.

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
Find f(3) and interpret its meaning.
Answer:
f(3) = 425
f(3) is the elevation of a mountain climber after 3 hours of climbing.
Step-by-step explanation:
So we are given a line that relates time to elevation. We are also given that the equation of the line is f(x) = 125x + 50. From looking at the graph given, we can see that x is the time, in hours, and y, or f(x), is the height, in feet. We are asked to find f(3) and interpret it's meaning.
To find f(3), we would have to find what f(x) is when x = 3. To do this, lets plug in 3 for x into the given equation:
f(3) = 125(3) + 50 = 425
So f(3) = 425. Now, we already know that x is the time in hours and y, or f(x), is the elevation in feet. We set x to 3 when solving for f(3). We have also found that f(3), or y when x = 3, is 425. So f(3), or 425, is the elevation after 3 hours.
I hope you find my answer and explanation to be helpful. Happy studying.
