Answer:
This circumference of the pond is 2πr (or 2π48), which equals 301.44m(assumine pi is 3.14). How long it takes to walk around depends on the rate of speed.
Find the arc length of the partial circle.
Either enter an exact answer in terms of π or use 3.14 π and enter your answer as a decimal.
Answer:
1/2 pi
Step-by-step explanation:
This is 1/4 of a circle
Find the circumference and multiply by 1/4
1/4 C
1/4 ( 2*pi*r) where r is the radius
The radius is 1
1/2 pi*1
1/2 pi
Answer:
Step-by-step explanation:
A full circle has a circumference of 2*pi * r
r = 1
so Full Circle = 2 * PI
1/4 Circle = 2*pi / 4 = 1/2 pi
The length of the arc length = 1/2 pi
Just in case you prefer the more numerical answer, 1/2 * 3.14 = 1.57

Math problem for high school
Answer:
50/3
Step-by-step explanation:
area of triangle = 10
area of circle = 10
area of triangle + area of circle = 20
The white sector of the circle has central angle 60°.
Its area is 1/6 the area of the circle.
To find the gray area, you must subtract the white area from the area of the circle and also subtract the white area from the area of the triangle. Two times the white area is 1/3 the area of the circle.
gray area = 20 - (1/3)10
gray area = 20 - 10/3
gray area = 60/3 - 10/3
gray area = 50/3
Answer:
The white sector of the circle = (1/6) (10) = 10/6 = 5/3
So....the grey area = 10 + 10 - 2 (5/3) = 20 - 10/3 = 60/3 - 10/3 = 50 / 3

(4.5y +9)-(6.2-3.1y)= 7.2y+2.8
Answer:
0
Step-by-step explanation:
(4.5y+9)-(6.2-3.1y)=7.2y+2.8
4.5y+9-6.2+3.1y=7.2y+2.8
4.5y+3.1y+9-6.2=7.2y+2.8
7.6y+2.8=7.2y+2.8
7.6y-7.2y=2.8-2.8
0.4y/0.4=0/0.4

Write a ratio and a percent for the shaded figure.
Total Squares = 10 × 10
= 100
Shaded Squares = 100 - (6×6)
= 64
Non Shaded = 6 × 6
= 36
Now Ratio of shaded portion is 64:100
= 16:25
Percentage = 64/100 × 100
= 64%

Given the expression: 4x10 − 64x2
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
Part B: Factor the entire expression completely. Show the steps of your work. (6 points)
Answer:
Step-by-step explanation:
a) 4x¹⁰ = 2² * x¹⁰
64x² = 2⁶ *x²
GCF = 2² * x² = 4x²
b) 4x¹⁰ - 64x² = 4x²*(x⁸ - 16)
=4x² *[ (x⁴)² - 4²]
= 4x² * (x⁴ + 4) (x⁴ - 4)
= 4x² * (x⁴ + 4)* [(x²)²- 2²]
=4x² * (x⁴ + 4) * (x² + 2)(x² - 2)

pls help i need the answer soon
Answer:
[tex]x = 2.4[/tex]
Step-by-step explanation:
Step 1: Find the length of AB
[tex]\frac{ED}{EA} = \frac{EC}{EB}[/tex]
[tex]\frac{15}{12} = \frac{18}{12+x}[/tex]
Cross Multiply
[tex]15(12+x) = 12(18)[/tex]
Distribute
[tex](15*12)+(15*x) = 216[/tex]
[tex]180 + 15x = 216[/tex]
Divide
[tex]15x / 15 = 36 / 15[/tex]
[tex]x = 2.4[/tex]
Answer: [tex]x = 2.4[/tex]
You used 6 3/4 cups of sugar while baking muffins and nut bread for a class party. You used a total of 1 1/2 cups of sugar for the muffins. Your nutbread recipe calls for 1 3/4 cups of sugar per loaf. How many loaves of nutbread did you make?
Answer:
Step-by-step explanation:
1. Convert to decimals.
[tex]6\frac{3}{4}[/tex] = 6.75 cups of sugar - Total Sugar
[tex]1\frac{1}{2}[/tex] = 1.50 cups of sugar - Muffin Sugar
[tex]1\frac{3}{4}[/tex] = 1.75 cups of sugar - Nutbread sugar
2. Subtract muffin sugar from total sugar
6.75 cups total sugar - 1.50 cups fir muffins = 5.25 cups remaining
3. Divide remaining sugar by amount used per loaf nutbread
5.25 cups sugar / 1.75 cups for each loaf nutbread = 3
3 Loaves of nutbread were made.

A group of eight golfers paid $445 to play a round of golf. Of the golfers, one is a member of the club and seven are nonmembers. Another group of golfers consists of three members and two nonmembers. They paid a total of $195 . What is the cost for a member to play a round of golf, and what is the cost for a nonmember?
Answer:
the cost for a member to play a round of golf: $95
the cost for a nonmember: $50
Step-by-step explanation:
the cost for a member to play a round of golf: $x
the cost for a nonmember: $y
x+7y=445
x+2y=195
=> y=50, x=95
Answer:
member: $95, nonmember: $50

PLEASE HELP! If 2580 people watched one show and 2920 people watched another show. How many people need to watch the third show for there to be a 3000 people average attendance per show?
Answer:
3480
Step-by-step explanation:
Set it up so it looks like this.
(2580 + 2930 + x )/3 = 3000 Combine the terms on the left
(5510 + x) / 3 = 3000 Multiply by 3
5510 + x = 9000 Subtract 5510
x = 9000 - 5510
x = 3490
Does that really work?
2580 + 2930 + 3490 = 9000
Which says it does work.
Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers
1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number
Answer:
option 3.
Step-by-step explanation:
alright, ima explain each option.
1. "smallest odd numbers" 2 is an even number. that's out of the playing field.
2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.
3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]
4. they do multiply to 30, but this does not help break the composite numbers down.
5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.
