PLEASE ANSWER
each angle of a regular pentagon measures 108 degrees is it possible to fit copies of a regular pentagon snugly around a point if yes how many copies does it take if not why not ?
Answer:
mark brainliest please.
Step-by-step explanation:
Three copies of a regular hexagon snugly around a point because 360 ÷ 120 = 3. Each interior angle of a regular pentagon measures 108°. 360 ÷ 108 = 3 1/3, which is not a whole number. This means that it would not be possible to fit the copies of a regular pentagon snugly around a point.
Tom is 4 inches taller than Sally together their heights equal 124 inches
a.create an equation to represent the situation.
b.Solve your equation
c. How tall is Sally?
d. How tall is Tom?
Answer:
Tom's height = x = 64 inches
Sally's height = y = 60 inches
Step-by-step explanation:
Let us represent
Tom's height = x
Sally's height = y
Tom is 4 inches taller than Sally
x = y + 4
Together their heights equal 124 inches
x + y = 124
We substitute y + 4 for x
y + 4 + y = 124
2y + 4 = 124
Collect like terms
2y = 124 - 4
2y = 120
y = 120/2
y = 60
Solving for x
x = y + 4
x = 60 + 4
x = 64
Therefore,
Tom's height = x = 64 inches
Sally's height = y = 60 inches

Polly’s Pasta and Pizza Supply sells wholesale goods to local restaurants. They keep track of revenue earned from selling kitchen supplies and food products. The function K m odels revenue from kitchen supplies in a given month and the function F models revenue from food product sales for a given month, where t represents the number of the month (January is month 1, February is month 2, etc.)
Complete question :
Polly’s Pasta and Pizza Supply sells wholesale goods to local restaurants. They keep track of revenue earned from selling kitchen supplies and food products. The function K models revenue from kitchen supplies and the function F models revenue from food product sales for one year in dollars, where t represents the number of the month (1 – 12) on the last day of the month.
K(t)=15t^3–312t^2+1600t+1100
F(t)=36t3–720t2+3800t–1600
In which month was her revenue from food products the greatest? The least?
Answer:
greatest revenue = 4384
Leat revenue = 400 ; October
Step-by-step explanation:
Using the model :
Claculating the revenue from. Food sales from January through December :
F(t)=36t^3–720t^2+3800t–1600
Put t = 1, 2, 3,.. 12 for January through December
t = 1
F(1)=36(1^3) - 720(1^2) + 3800(1) - 1600 = 1516
t = 2
F(2) = 36(2^3) - 720(2^2) + 3800(2) - 1600 = 3408
Inputting the t values up to 12 to cover for January thkorugh December :
We have the data:
t1 = 1516
t2 = 3408
t3 = 4292
t4 = 4384
t5 = 3900
t6 = 3056
t7 = 2068
t8 = 1152
t9 = 514
t10 = 400
t11 = 996
t12 = 2528
Hence, greatest revenue = 4384 (month of April)
Least revenue is at t10(October) ; Lowest revenue is at t 10 = 400

Step-by-step explanation:
A line has a slope of m = 3/4 and goes through the point (16, -2). Which of these is the equation of the line?
Answer:
y = (3/4)*x - 14
Step-by-step explanation:
The slope-point general equation of the straight line is:
y = m*x + b
In that equation, m is the slope and b is the intercept with y-axis
The equation has two parameters to determine m and b. for a different pair of values we get just one unique straight line equation. To do that we need two conditions.
Here we have m = 3/4 and the point P ( 16 , -2), by substitution
y = (3/4)*x + b and
- 2 = (3/4)*16 + b - 2 = 3*4 +b -2 = 12 +b b = -14
Then the final equation is:
y = (3/4)*x - 14

4/5 - 1/10=
A. 7/10
B.3/5
C.3/10
D.2/25
Answer
A 7/10
Step-by-step explanation:
if you make it even, you double the 4/5 to make it a 8/10, if you every have a number that is like 4/6-2/18, you triple the 4 to make 12, and triple the 6 to make it 18. so you now have 12/18-2/18=10
So 8/10-1/10=7/10

The length of a rectangle is 5 centimeters less than 2 times the width.
a. Write a polynomial expression that represents ( 2 points )
the area of the rectangle. Simplify the expression.
Find the area of the rectangle when width is 10 centimeters.
Answer:
A = 2w² - 5w
150 sq.cm
Step-by-step explanation:
Let the length be L and width be w
If the length of a rectangle is 5 centimeters less than 2 times the width, then;
L = 2w - 5
Area of the rectangle A = Lw
Since L = 2w - 5
A = (2w-5)w
Expand
A = 2w² - 5w
b) if w = 10cm
A = 2w² - 5w
A = 2(10)² - 5(10)
A = 200 - 50
A = 150 sq.cm
Hence the required area is 150 sq.cm

Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom bought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups.
Answer:
Cups = 24
Plates = 48
Balloons = 12
Total = 84
Step-by-step explanation:
Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom brought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups. If Serena's mom bought 84 items, how many of each item did she buy.
Let
c = number of cups
Serena's mom bought twice as many plates as cups.
2c = number of plates
number of balloons Serena's mom bought was half the number of cups
0.5c = the number of balloons
Total items = 84
c + 2c + 0.5c = 84
3.5c = 84
Divide both sides by 3.5
3.5c / 3.5 = 84 / 3.5
c = 24
c = number of cups = 24
2c = number of plates = 2 * 24 = 48
0.5c = the number of balloons = 0.5*24 = 12
Cups = 24
Plates = 48
Balloons = 12
Total = 84

Akiko ate 60 hot dogs in 10 hours. At that rate, how many hot dogs would she eat in 20 minutes?
Akiko ate per hour:-
Total hot dogs/Total hours60/106dogs/hourSo
20min=1/3h
Total hot dogs
6/32Answer:
2 hot dogs
Step-by-step explanation:
Total hot dogs she ate in 10 hours,
→ 60 hot dogs
Total hot dogs she ate in 1 hour,
→ 60/10
→ 6 hot dogs
The fraction of 20 minutes in a hour,
→ 20 minutes/1 hour
→ 20/60
→ 2/6 = [ 1/3 ]
Rate of hot dogs she ate in 20 minutes,
→ 6 × 1/3
→ 6/3
→ [ 2 hot dogs ]
So, Akiko ate 2 hot dogs in 20 minutes.

Helen recorded the number of tomatoes on each of her tomato plants and then arranged the numbers from smallest to largest. The number of tomatoes on each plant were 5, 5, 5, 6, 9, 10, 10,10, 10, and 10. The mean number of tomatoes was 8. What is the mean absolute deviation?
Answer:
2.2
Step-by-step explanation:
Given the data :
X = 5, 5, 5, 6, 9, 10, 10,10, 10, and 10
Mean of the data, xbar = 8
The mean absolute deviation, MAD is obtained thus :
Σ|x - xbar| / n
n = sample size
Σ|x - xbar| = (3 + 3 + 3 + 2 + 1 + 2 + 2 + 2 + 2 + 2)
Σ|x - xbar| / n = 22 / 10
MAD = 2.2
Tyler has a stack of cards. He picks a card, records the color, and returns the card to the stack. He repeats this 60 times and chooses a red card 24 times. What is the experimental probability of choosing a red card from the stack?
Answer:
24/60 = 2/5
Step-by-step explanation: dont have one
Answer:
2/5, or 40%
Step-by-step explanation:
The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.
