John earns $437 a week after a 15% pay rise. What was his pay initially? Round your answer to the nearest dollar.
Answer:
380 dollars
Step-by-step explanation:
John earns $437 a week after a 15% pay rise.
Let the initially pay of John be x
x + (15% of x) = 437
x + 0.15x = 437
1.15x = 437
x = \frac{437}{1.15}
1.15

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train. If the two trains are 480 miles apart after 3 hours, what is the rate of the eastbound train?
73 is the rate of the eastbound train while The speed of the westbound train is 59 miles per hour.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train.
Eastbound train:
time = 3 hrs, rate = x mph, distance = 3x miles
Westbound train:
time = 3 hrs ; rate = x-14 ; distance = 3x-42 miles
3x + 3x - 42 = 480
6x = 438
x = 73 (rate of the eastbound train)
To find the rate of the westbound train:
rate = x -14
rate = 73 - 14
rate of westbound train = 59
Therefore, The speed of the westbound train is 59 miles per hour.

Write a paragraph proof for the following conjecture: m∠1 + m∠2 = m∠4
Prove: m∠3 + m∠1 + m∠2 = 180°
Given: ∠1 + ∠2 = ∠ 4
∠4 + ∠3 must be 180° because they are supplementary
If ∠4 + ∠3 is 180, and ∠1 + ∠2 = ∠4, you can substitute ∠4 in the first equation for ∠1 + ∠2.
Hence, we arrive at the answer ∠1 + ∠2 + ∠3 = 180.

Answer:
0.64761904761
Step-by-step explanation:
A couple realizes a real estate financing of R $ 180,000.00, to be paid in 360 monthly installments, with an effective interest rate of 1% per month. The first installment is paid one month after the funds are released and the monthly installment is R $ 500.00 plus 1% interest on the outstanding balance (amount due before payment). Note that, with each payment, the outstanding balance is reduced by R $ 500.00 and consider that there is no arrears. By making the payment in this way, the amount, in reais, to be paid to the bank in the tenth installment is
a) 2,075.00.
b) 2,093.00.
c) 2,138.00.
d) 2 255.00.
e) 2 300.00.
Answer:
ANSWER: letter D
Step-by-step explanation:
In the tenth installment, the debit balance is, in reais, of
180000 - 9. 500 = 175500
The 1% interest on this amount results in:
1% . 175 500 = 1755
Thus, the tenth installment is, in reais, 500 + 1755 = 2255

You track inventory at a furniture store. On Monday, the delivery truck delivers 15 new mattresses. Your team sells seven mattresses on Monday, two mattresses on Tuesday, zero on Wednesday, and five on Thursday. You receive a new order Friday morning of 15 mattresses. How many mattresses do you now have available?
Answer: 16
Step-by-step explanation: You started with 15 , you lose 7 Monday which leaves you with 8 , 2 on Tuesday which leaves you with 6 , 5 on Thursday which leaves you with 1 and then you received 15 on Friday which brings you to 16
The number of mattresses available now is 16.
Given that, On Monday, the delivery truck delivers 15 new mattresses. Number of mattresses sold on Monday=7, number of mattresses sold on Tuesday=2, number of mattresses sold on Wednesday=0, and number of mattresses sold on Thursday=5.
What is an equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.
Let number of mattresses do you now have available be x.
Given that, receive a new order Friday morning of 15 mattresses.
So, x=15-(7+2+0+5)+15
=30-14=16
Therefore, the number of mattresses available now is 16.

Robin can clean 727272 rooms in 666 days. how many rooms do she clean in 9 days
Answer:
Robin can clean 9828 rooms in 9 days
Step-by-step explanation:
Since Robin can clean 727272 rooms in 666 days, we can find how many rooms she can clean in 1 day by dividing 727272 by 666
number of rooms cleaned by Robin in 1 day = 727272 rooms/666 days = 1092 rooms/day
We can then find how many rooms she can clean in 9 days by multiplying 1092 by 9
1092 rooms/day * 9 days = 9829 rooms
What is one third of 1296?
Answer:
four hundred thirty-two

= 1 × 1296 / 3
= 1296/3
Let us try to simplify this fraction . Both the numerator and the denominator is divisible by 3 .
Then ,
= 1296 ÷ 3 / 3 ÷ 3
= 432/1
= 432
Therefore , one third of 1296 is 432
