Answer:
The weight of the water in the pool is approximately 60,000 lb·f
Step-by-step explanation:
The details of the swimming pool are;
The dimensions of the rectangular cross-section of the swimming pool = 10 feet × 20 feet
The depth of the pool = 5 feet
The density of the water in the pool = 60 pounds per cubic foot
From the question, we have;
The weight of the water in Pound force = W = The volume of water in the pool given in ft.³ × The density of water in the pool given in lb/ft.³ × Acceleration due to gravity, g
The volume of water in the pool = Cross-sectional area × Depth
∴ The volume of water in the pool = 10 ft. × 20 ft. × 5 ft. = 1,000 ft.³
Acceleration due to gravity, g ≈ 32.09 ft./s²
∴ W = 1,000 ft.³ × 60 lb/ft.³ × 32.09 ft./s² = 266,196.089 N
266,196.089 N ≈ 60,000 lb·f
The weight of the water in the pool ≈ 60,000 lb·f
James bought 3 books for $8 each and 4 DVDs for $15 each he paid with a $100 how much change did he receive?
Answer:
He received $16 change
Step-by-step explanation:
3 books for $18 is $24
4 DVDs for $15 is $60
His total is $84
$100 - $84 = $16
Answer:
6 dollars
Step-by-step explanation:
you multiply 3 by 8 which is 24. Then you multiply 4 by 15 and that's 70. So then you add 24 and 70 together which is 94. Lastly you subtract 94 from 100 and you get 6.

Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft2 and she painted 288 ft2 yellow, what percent of the room did she paint green?
Answer:
Total percent of the room did she paint green = 60%
Step-by-step explanation:
Given - Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft² and she painted 288 ft² yellow.
To find - What percent of the room did she paint green ?
Proof -
Given that,
The surface area of the walls in her room = 720 ft²
Total area painted in yellow color = 288 ft²
So,
Total area painted in green color would be = 720 - 288 = 432 ft²
Now,
Let the total percent green color painted = x
So,
720 × x% = 432
⇒[tex]720*\frac{x}{100} = 432[/tex]
⇒ x = [tex]\frac{432*100}{720}[/tex] = 60
∴ we get
Total percent of the room did she paint green = 60%

Answer: reminder u are loved. <3
Step-by-step explanation:
the topic is piecewise functions, can someone help? i’m a little confused :)
Given:
The piecewise function is:
[tex]f(x)=\begin{cases}x+5&x<-2\\x^2+2x+3&x\geq -2\end{cases}[/tex]
To find:
The values of [tex]f(-4),f(-2),f(0),f(3)[/tex].
Solution:
For [tex]x<-2[/tex], the function is
[tex]f(x)=x+5[/tex]
For [tex]x\geq -2[/tex], the function is
[tex]f(x)=x^2+2x+3[/tex]
a) The value of [tex]f(-4)[/tex] is:
[tex]f(-4)=-4+5[/tex]
[tex]f(-4)=1[/tex]
b) The value of [tex]f(-2)[/tex] is:
[tex]f(-2)=(-2)^2+2(-2)+3[/tex]
[tex]f(-2)=4-4+3[/tex]
[tex]f(-2)=3[/tex]
c) The value of [tex]f(0)[/tex] is:
[tex]f(0)=(0)^2+2(0)+3[/tex]
[tex]f(0)=0-0+3[/tex]
[tex]f(0)=3[/tex]
d) The value of [tex]f(3)[/tex] is:
[tex]f(3)=(3)^2+2(3)+3[/tex]
[tex]f(3)=9+6+3[/tex]
[tex]f(3)=18[/tex]
Therefore, the required values are [tex]f(-4)=1,f(-2)=3,f(0)=3,f(3)=18[/tex].
what is 2x-15+21= -18
Answer:
2x - 15 +21 = -18
2x + 6 + 18 = 0
2x + 24 =0 ...it is a linear equation
if u want to solve for X then..
2x = -24
X = - 24

How to solve this triangle, please help me.
Answer:
sum of angles in a triangle is 180
so 70+60+ 8x+2 = 180
132+ 8x = 180
8x = 180-132
x = 48/8
x= 6
then find the angle by substituting value of x
8x + 2
8*6 + 2
= 50°
what is the value of x
Step-by-step explanation:
2x = x + 11
x = 11

f(1) = -3
f(n) = 2. f(n − 1) +1
f(2)=
f ( 2 ) = 2 × f ( 2 - 1 ) + 1
f ( 2 ) = 2 × f ( 1 ) + 1
f ( 2 ) = 2 × ( - 3 ) + 1
f ( 2 ) = - 6 + 1
f ( 2 ) = - 5

Answer:

Step-by-step explanation:
Calculate distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
(1) with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 8)
d = [tex]\sqrt{6-0)^2+(8-0)^2}[/tex]
= √(6² + 8²)
= √ (36 + 64)
= √ 100
= 10 → B
(2)
Using (x₁, y₁ ) = (- 5, 3) and (x₂, y₂ ) = (3, 15)
d = √ (3 + 5)² + (15 - 3)²
= √ 8² + 12²
= √ 64 + 144
= √ 208
≈ 14.4 ( to the nearest tenth ) → A

Blake, Chang, and Grace together sold 71 tickets for the school banquet. Blake sold 27 tickets and Chang sold 28 tickets. How many tickets did Grace sell? (5 points) 16 43 44 55
Answer:
16
Step-by-step explanation:
because to get what you need add 27 and 28 and you get 55 then subtract 71 by 55 to get 16
71-(27+28)
Answer:
Grace sold 16 tickets.
Step-by-step explanation:
We have a total of 71 tickets sold between 3 people. Blake sold 27 tickets and Chang sold 28 tickets. Adding those sold by Blake and those sold by Chang, gives us: 27 + 28 = 55, if that amount is subtracted from the total sales that are 71 tickets, the result would be: 71 - 55 = 16, which would be the tickets sold by Grace.
