The perimeter of a rectangular pool is 240 yd. If the length is 30 yd unless the four times the width, find the length and the width.
Answer:
270 is the answer if you add
Answer:
Step-by-step explanation:
P = 2L + 2W
L = 4w - 30
w = w
P = 2(4w - 30) + 2W
but P = 240
2(4w - 30) + 2w = 240 Remove the brackets.
8w - 60 + 2w = 240 Combine
10w - 60 = 240 Add 60
10w - 60 + 60 = 240+60 Combine
10w = 300 Divide by 10
w = 30
L = 4w - 30
L = 4*30 - 30
L = 120 - 30
L = 90

larry mitchell invested part of his $27,000 advance at 2% annual simple interest and the rest at 6% annual simple interest. If his total yearly interest from both accounts was $860, find the amount invested at each rate
Answer:
$19000 at 2%, $8000 at 6%Step-by-step explanation:
Let x is the amount at 2%, then 27000 - x is the amount at 6%.
The total interest is:
0.02x + 0.06(27000 - x) = 8600.02x - 0.06x + 1620 = 8600.04x = 1620 - 8600.04x = 760x = 760/0.04x = 19000The amount at 6% is:
$27000 - $19000 = $8000Find the distance between each pair of points.
(6,2), (-2,6)
Help please!!
Answer:
This represents an absolute value graph, therefore the distance between them is 8.944272
Step-by-step explanation:
d = 8.944272
For:
(X1, Y1) = (6, 2)
(X2, Y2) = (-2, 6)
Distance Equation Solution:
d=(−2−6)2+(6−2)2−−−−−−−−−−−−−−−−√
d=(−8)2+(4)2−−−−−−−−−−√
d=64+16−−−−−−√
d=80−−√
d=8.944272

What’s -4 1/2 divided by (-1 3/8) Diving Mixed Numbers with negatives?
Answer:
3 3/11
Step-by-step explanation:
The best way to divide fractions is to not divide them at all.
Convert both mixed numbers into improper fractions.
4 times 2 is 8
8 + 1 is 9
I have 9/2 halves. Don't forget to put the negative back in.
1 times 8 is 8
8 + 3 is 11
I have 11/8 eighths. Dont forget to put the negative back in.
You will end up with
-9/2 ÷ -11/8
Flip the second fraction and change the division sign to a multiply sign
-9/2 × 8/-11
Multiply the numerators together and the denominators together
-9 x 8 and 2 x -11
-72 / -22
Dividing a negative by a negative will give us a positive
72 / 22
Simplify by dividing the top and bottom by 2

[tex] = - 4 \frac{1}{2} \div -1 \frac{3}{8} [/tex]
[tex] = \frac{(2 \times ( - 4) + 1)}{2} \div \frac{(8 \times ( - 1) + 3}{8} [/tex]
[tex] = \frac{ - 7}{2} \div \frac{ - 5}{8} [/tex]
[tex]= \frac{ - 7}{2} \times \frac{8}{ - 5} [/tex]

Answer:
f(4) = (4-1) = 3
f(2) = (2-1) = 1
f(-27) = (-27 -1) = -28
There isn't any error while describing the functions and everything looks fine.

At a sale this week, a table is being sold for $403. This is a 38% discount from the original price. What is the original price?
Answer:
$650. This was the original price.
Step-by-step explanation:
Let p represent the original price.
The following expression calculates the value of p: (1 - 0.38)p = $403. Note that '1' indicates full price and that '0.38' indicates a 38% discount.
(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.
Dividing both sides by 0.62 yields $650. This was the original price.
Answer:
$650
Step-by-step explanation:
Line up $ with $ and % with % then cross multiply
$403 represents ........100% full price -38% discounted = 62%
$ x amount of the original price represents .........................100%
x*62 = 403*100, cross multiply
x = (403*100)/62, divide both sides by 62
x = $650

A Ferris wheel can accommodate 40 people in 20 minutes. How many people
could ride the ferris wheel in 3 hours? What was that rate per hour?
Answer:
360 people in 3 hours. 120 people per hour.
Step-by-step explanation:
How many times do 20 minutes go into 3 hours?
Well, 60 min. ÷ 20 min. = 3
So, 3 x 3 = 9
So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.
So 3 hours would be 9 x 40 = 360
120 people per hour because 40 x 3 = 120
and 20 minutes (3) times equals 1 hour.

m=y2-y1/x2-x1 solve for x2
Answer:
[tex]x2=\frac{y2-y1}{m} +x1[/tex]
Step-by-step explanation:
Step 1: Multiply both sides by (x2-x1)
m(x2-x1)=y2-y1
Step 2: Divide both sides by m
x2-x1=(y2-y1)/m
Step 3: Add x1 to both sides
[tex]x2=\frac{y2-y1}{m} +x1[/tex]
Find the general solution of the given higher-order differential equation. y''' − 7y'' + 8y' + 16y = 0
The ODE
y''' - 7y'' + 8y' + 16y = 0
has characteristic equation
r ³ - 7r ² + 8r + 16 = 0
which can be factorized as
(r - 4)² (r + 1) = 0
Then the characteristic solution to the ODE is
y(x) = C₁ e ⁴ˣ + C₂ x e ⁴ˣ + C₃ e ⁻ˣ
