Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

Darryl Dixon shoots an arrow at a zombie. The path of the arrow can be modeled with the equation y=-x^2 42x-80, where x is time in seconds and y is the height in feet. How long does it take for the arrow to reach its maximum?

Answers

We need to find time taken to reach arrow to its maximum.

The path of the arrow can be modeled with the equation [tex]y=-x^2+ 42x-80[/tex] .

Differentiating the given equation w.r.t x and equate it to zero.

[tex]\dfrac{dy}{dx}=-2x + 42 \\\\42 - 2x = 0\\\\x = 21\ seconds[/tex]

Putting value of x = 21 sec in given equation, we get :

[tex]y=-x^2+ 42x-80\\\\y = -(21)^2 + (42\times 21) - 80\\\\y = 361 \ feet[/tex]

Therefore, time taken to reach maximum height is 21 seconds.

A student pays for pounds of apples with a ​$ bill. How much change does the student​ receive? Answer parts a and b. a. What do you do first to solve the​ problem? ▼ the number of pounds of apples by the price per pound

Answers

A student pays for 8.9 pounds of apples with a 10$ bill. Its $1.09 per pound. How much change does the student receive? What do you do first to solve the​ problem?

Answer:

$0.299

Step-by-step explanation:

Given that :

Pounds of apple purchased = 8.9 pounds

Price per pounds of apple = $1.09

Bill issued = $10

First, we calculate the total cost of 8.9 pounds of apple :

(Number of pounds * price per pound)

($8.9 * 1.09) = $9.701

Amount of Change :

Bill issued - total cost

$10 - $9.701

= $0.299

Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21

Answers

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

(-10, 9)

Step-by-step explanation:

9x+9y=-9

Use substitution method

9(-10)+9y=-9

Order of operations(PEMDAS)

-90+9y=-9

Add 90 to both sides

(-90+90)+9y= -9+90

9y=81

Divide 9 from both sides

(9/9)y=81/9

y=9

Hope this helps. Have a nice day. May it be filled with joy and happiness. Please, stay safe and wash your hands. Happy Holidays.

Answer:

Step-by-step explanation:

in this case, we already know that x=   -10 so we can substitute in the other problem, -10x9 = -90 so now we can get rid of that by adding + 90 on each side making it 9y=81 by this time, we see that both sides are divisable by 9 divide both by nine and you get: 1y=9 from that you can finally answer the question with

x= -10 y= 9

(2x + 127)° = 107°
