A student earns Php 280.00 for a 5 hour shift on his summer job. The amount
of money he earns varies directly to the number of hours worked. Find the
constant k, and the amount of money he will earn for an 8-hour shift.

Answers

Answer 1

Answer:

y=k5, 448 after an 8 hour shift

Step-by-step explanation:

Answer 2

The amount of money he will earn for an 8-hour shift is Php448

Let the amount  of money he earns be A

Let the number of hours worked is "h"

If the amount  of money he earns varies directly to the number of hours worked is expressed as:

A = kx

k = A/x

GIven that A = Php 280.00, x = 5 hours

k = 280/5

k = 56

If x = 8 hours, the amount of money A = kx

A = 56 * 8

A = Php448

Hence the amount of money he will earn for an 8-hour shift is Php448

for every 6 white roses, there are 8 pink roses. If the floral arrangement is proportional then how many pink roses are in a arrangement with 10 white roses

Answers

Answer:

13.33 pink roses

Step-by-step explanation:

We are told the floral arrangements are proportional , hence:

6 white roses = 8 pink roses

10 white roses = x

Cross Multiply

6 white roses × x = 10 white rose × 8 pink roses

x = 10 white roses × 8 pink roses/6 white roses

x = 13.333333333 pink roses

x ≈ 13.33 pink roses

Step-by-step explanation:

If we know that d is 10 we can substitute d for 10 thus giving us 10 - 7 which is 3

Answer :

We are given,

d - 7 .....[eqⁿ (i)]

and we are also given the value of d :

d = 10

Now, just put the value of d = 10 in eqⁿ (i) we get :

10 - 73

Hence your final answer is 3.

I walk each day to school. By what percentage would I need to increase my usual average speed in order for the journey to take 20% less time than usual? C:

Answers

Answer:

25%

Step-by-step explanation:

Let v, t be the current average speed and the time taken to reach the school respectively.

As distance = speed x time, so,

distance, d=vt...(i)

Let V be the new average speed in order to to take 20% less time than t.

So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t

As distance is constant, so

d= V(0.8t)= 0.8Vt

hBy using equation (i), we have

0.8Vt = vt

0.8 V = v

V= v/0.8=1.25v

Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]

[tex]=\frac{1.25v-v}{v}\times 100[/tex]

=25%

Hence, the percentage increase in the average speed is 25%.

17 apples and 12 oranges cost $10.44. 3 apples and 4 oranges cost $2.84. How much does 1 orange cost?

Answers

Answer:

0.48$

Step-by-step explanation:

Cost of 1 Apple = A

 

Cost of 1 Orange = O

 

 

Six apples and three oranges cost $3.36 equivalent to:

 

6A + 3O = 3.36 (1st equation).

 

Two apples and five oranges cost $3.04 equivalent to:

 

2A + 5O = 3.04 (2nd equation).

 

 

Now we have to solve the 2 equations with 2 uknowns (the cost of 1 Apple = A, and the cost of 1 Orange = O).

 

6A + 3O = 3.36 (Equation 1)

2A + 5O = 3.04 (Equation 2), multiplying this equation by 3 we get:

 

6A + 3O = 3.36 (Equation 1)

6A + 15O = 9.12 (Equation 2), Now equation 2 minus equation 1 we get:

 

 

6A-6A +15O -3O = 9.12-3.36 equivalent to:

 

12O = 5.76 => O = 5.76/12 = 0.48 ( the cost of one Orange is 0.48$)

 

Go back to equation 1 and solve for the cost of 1 apple:

 

6A + 3x0.48 = 3.36 =>

6A + 1.44 = 3.36 =>

6A = 1.92 =>

A = 1.92/6 = 0.32 ( the cost of one apple is 0.32$)

 

Summary: The cost of one apple is 0.32$ and the cost of one orange is 0.48$.

The answer is 48¢... Hope it helps!!

Answer: (4,2). Explanation: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable. The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
variable equation. It is relatively difficult to determine the values of x and y without manipulating the equations. If one adds the two equations together, the x s cancel out; the x is eliminated from the problem. Hence it is called the "elimination method”.

Hey guys this is confusing, someone plz help

Answers

Answer: x = 13

Step-by-step explanation:

To find the value of x, you have to find ∠QRP

∠QRP + ∠QRS = 180

∠QRP + 95 = 180

Subtract 95 from both sides

∠QRP = 85

∠RQP + ∠QPR + ∠QRP = 180   Definition of triangle

(4x + 3) + (3x + 1) + 85 = 180

Subtract 85 from both sides

(4x + 3) + (3x + 1) = 95

7x + 4 = 95

Subtract 4 from both sides

7x = 91

Divide 7 from both sides

x = 13
