Two planes leave an airport at the same​ time, one flying​ east, the other flying west. The eastbound plane travels 130 mph slower. They are 3850 mi apart after 5 hr. Find the speed of each plane.

Answers

Answer:

Speed of the slower plane = 320 mph

Speed of the faster plane = 450 mph

Step-by-step explanation:

Let the speed of the slower plane = x mph

And the speed of the faster plane = y mph

Difference in their speeds = 130 mph

y - x = 130 --------(1)

Formula for the distance traveled = Speed × time

Distance traveled by the faster plane in 5 hours = 5y miles

Distance traveled by the slower plane in 5 hours = 5x miles

Total distance traveled by both the planes in 5 hours = 5(x + y) miles

5(x + y) = 3850

x + y = 770 ---------(2)

By adding equations (1) and (2)

2y = 900

y = 450 mph

From equation (2)

x = 770 - 450

x = 320 mph

You can work a total of no more than 15 hours each week at your two jobs. Housecleaning pays $8 per hour and your sales job pays $10 per hour.
You need to earn at least $130 each week to pay your bills.

Write a system of inequalities to represent this situation. DO NOT SOLVE.
Let x = # of hours housecleaning and y = # of hours at the sales job

8x + 10y = 130 is the equation

The table above shows the height of a plant
at the end of each week. The height
increases by the same amount each week. If
this pattern continues, what will be the
height, in inches, of the plant at the end of
the 7th week?
(A) 1.25 in
(B) 1.50 in
(C) 1.75 in
(D) 2.00 in

Answers

Answer:

(C) 1.75 in

Step-by-step explanation:

It give you a clue in the question that the height increases by the same amount each week. This means that if you add 0.25 you will get a constant answer. What I mean by constant is this :-

0.25 + 0.25 = 0.5 in

I can also do it by multiplying it by 2.

2 × 0.25 = 0.5 in

If you add 0.25 every time or if you multiply 0.25 by the number of weeks you will get your answer same. So,

7 × 0.25 = 1.75 in

Hope this helps, thank you !!

Substitute for "g" and solve for "b"::

 

b+38 + b = 48

2b = 10

b = 5 (# of blue marbles)

Find the 25th term in the arithmetic sequence: 23, 223, 423, 623,...

Answers

Answer:

Step-by-step explanation:

Assuming that 23 is the first term

4823

25th term of arithmetic sequence is 4,823

Given arithmetic sequence:

23, 223, 423, 623,...

Find:

25th term of arithmetic sequence

Computation:

First term a = 23

Common difference d = A2 - A1

Common difference d = 223 - 23

Common difference d = 200

Number of term n = 25

So,

An = a + (n - 1)d

A25 = 23 + (25 - 1)(200)

A25 = 23 + (24)(200)

A25 = 23 + 4,800

A25 = 4,823

Hester sells televisions. she earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Hester sells 13 televisions with extended​ warranties, she earns 13,00. How much is the fixed amount earns for each​ television?

Answers

Using proportions, it is found that the fixed amount that she earns for each television is of $70.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, she sold 13 televisions with warranty, hence earning a total in bonus of 13 x $30 = $390.

Hence, the sum of the 13 fixed amounts is of 1300 - 390 = 910, hence the fixed amount she earns is given by:

$910/13 = 70.

Therefore, c/e in the original position = e'/d in the flipped position.
