At a high school football game, 4 out of every 7 students in line to buy a ticket wore a hat.
If 350 students bought a ticket, how many students wore a hat? How many students did not wear a hat?
Be sure to answer both questions in sentence form. Also, describe how you got your answers in sentence form.
Answer:
Out of 350 students in line, 200 of them wore a hat.
Out of 350 students, 150 did not wear a hat.
Step-by-step explanation:
I divided 350 by 7 and got 50. Then, I multiplied 50 by 4 (the number of students out of 7 that wore a hat) to get 200, which is the number of students in line that did wear a hat. The rest did not wear a hat, so to find that number I subtracted 200 from 350 and got 150, which is the number of students that didn't wear a hat.
hope this helps :)
Answer:
200 kids wore a hat, and 150 kids did not wear a hat.
Step-by-step explanation:
first, we need to find out how many "batches" of 7 students there are. 350 divided by 7 = 50. now, we can do 4*50 because that's how many "batches" of students there are. 4*50=200. 200 kids wore a hat. as for the kids who didn't wear a hat, 350-200=150 students with no hats.
Which statements apply to the expression (three-fifths) cubed? Check all that apply. The base is Three-fifths. The base is 3. The exponent is 3. The expanded form is Three-fifths times three-fifths times three-fifths. The expanded form is StartFraction 3 times 3 times 3 Over 5 EndFraction. (Three-fifths) cubed = StartFraction 9 Over 15 EndFraction (Three-fifths) cubed = StartFraction 27 Over 125 EndFraction
Answer:
The answers are 1, 3, 4, 7
the base is 3/5
the exponent is 3

The perimeter of a rectangle is 40 feet its length is 12 feet what is the width
Answer:
8 feet
Step-by-step explanation:
In a rectangle
length (L) = 12 feet
perimeter (p) = 40 feet
width (b) = ?
We know
p = 2(L + b)
40 = 2 ( 12 + b)
40/2 = 12 + b
20 = 12 + b
b = 20 - 12
b = 8 feet
Answer:
12 feet
Step-by-step explanation:
Perimeter of rectangle = 2( l + b )
40 = 2( 12 + b )
40 = 24 + 2b
40 - 24 / 2 = b
12 feet = b (width)

Answer:
1. 34 2. 4.42 3. A
Step-by-step explanation:
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
Answer:
length of foot = y
length of forearm = x = 17
Equation: y = 0.860x + 3.302
Plug in 17 for x in the equation, and simplify. Remember to follow PEMDAS, first multiply, then combine like terms:
y = (0.860)(17) + 3.302
y = 14.62 + 3.302
y = 17.922
length of foot = y = 17.922 inches long
Step-by-step explanation:
If the forearm of a person is 17 inches long then his foot would be 17.922 inches long.
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
We have been given an equation y = 0.860x + 3.302
y = length of the foot and x = length of the forearm
The equation below can be used to find the length of a foot or forearm when you know one or the other.
We need to find the foot of a person be if his forearm was 17 inches long.
For x = 17 inches, we need to find the value of y.
Substitute x = 17 in the given equation.
⇒ y = 0.860x + 3.302
⇒ y = 0.860 (17) + 3.302
⇒ y = 14.62 + 3.302
⇒ y = 17.922
Therefore, if the forearm of a person is 17 inches long then his foot would be 17.922 inches long.

Darryl deposits $ 1,500.00 into a savings account that has a simple interest rate of 2.7% Lori deposits $ 1,400.00 into a savings account that has a simple interest rate of 3.8% If no other transactions are made whose account will have more money after 10 years?
Answer:
Daryl
He deposits $1,500 at an interest rate of 2.7%
We now turn the percentage into a decimal 2.7%--->0.027
We multiply $1,500 x [tex]1.027^{10}[/tex] to get 1,957.92
Lori deposits $1,400 at an interest rate of 3.8%
We once again turn the percentage into a decimal 3.8%--->0.038
We multiply $1,400 x [tex]1.038^{10}[/tex] to get 2032.83
Meaning Lori has more at the ned of the 10 years
