The designer sketched a model of the pond. The model drawing had a circumference of 24 inches. What is the AREA of the model she drew? Show your work. Round your answer to the nearest tenth.
Answer:
Area of model pond = 45.6 inch² (Approx.)
Step-by-step explanation:
Given:
Circumference of circular pond = 24 inches
Find:
Area of model pond
Computation:
Circumference of circle = 2πr
Circumference of circular pond = 2πr
24 = 2[22/7][r]
Radius r = [24 x 7] / [2 x 22]
Radius r = 3.81 inch (Approx.)
Area of circle = πr²
Area of model pond = πr²
Area of model pond = (22/7)(3.81)²
Area of model pond = [3.1428][14.5161]
Area of model pond = 45.6 inch² (Approx.)

What whole number best approximates the value of x?
The answer is 87
For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up
Hope this helps :)

A woman bought a bag of rice for $5700 and in 3 weeks later,she could only buy 3/4 of a bag for $5700. Find the percentage increase.
Answer: 25%
Step-by-step explanation:
3/4x=5700
x = 7600
7600 - 5700 = 1900
19/76 = 25/100 which is 25%
Hope this helps!
what would I put to show my work?
Answer:
x = 23
Step-by-step explanation:
These are supplementary angles so the sum of those angles add up to 180:
3x + 16 + 5x - 20 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23
70% of s is 455, what is s?
Answer:
650
Step-by-step explanation:
[tex]7/10s = 455\\7s = 4550\\s = 650[/tex]
Answer:
650
Step-by-step explanation:
[tex]\frac{70}{100} =\frac{455}{y}[/tex]
First, to answer this you cross multiply. This means:
[tex]45,500=70y[/tex]
Now you divide each side by 70, and you get 650
The length of a rectangle is 3yd longer than its width. If the perimeter of the rectangle is 26 yd ,find its area
Answer:
A=40
Step-by-step explanation:
There are two sides of a rectangle that are the length.
So at 3 twice.
3+3=6
Subtract it from 26.
26-6=20
Divide by 4
20/4=5
Width= 5
Add 3 to 5
3+5=8
L=8
Check:
5+8+5+8=26
10+16=26
26=26
Area= L*W
8x5=40
A=40
Hope I'm correct!
Guys pls help me!!!!!!
Answer:
Horizontal lines have no vertical change -- it continues straight left or right. In other words, the change in the y values between any points on the graph is 0, since there is no change. This means that the slope of a horizontal line is 0
Step-by-step explanation:
hope this helps
Answer:
0
Step-by-step explanation:
The line's slope remains constant throughout, its a line that passes through the y - axis therefore it's slope will be 0.
Which number is an integer?
Answer:
Step-by-step explanation:
Can you please specify on that question
Answer:
Integers are numbers that include the negatives, zero and positives.
Step-by-step explanation:
If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!
First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.
Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.
Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.
Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.
I hope this strategy helped and if it didn't here's that circle chart!!
I really hope this did help tho!!
Find the volume of the cone. Round your answer to the nearest tenth.
8 ft.
2 ft.
Answer:
134 is your answer hope it helps
Step-by-step explanation:
Happy Paws charges $20.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answer:
8 hours
Step-by-step explanation:
Create an equation that sets the costs equal to each other, where h is the number of hours
3.5h + 20 = 4.75h + 10
Solve for h
3.5h + 20 = 4.75h + 10
20 = 1.25h + 10
10 = 1.25h
8 = h
So, it will take 8 hours for the costs to be equal

13 = r
Find the area of the trapezoid, I will give brainlist. If you can please explain how you got the answer
Answer:
36 sq inches
Step-by-step explanation:
bases are the two parallel sides -- 8" and 4"
height is perpendicular to the base -- 6"
formula for area of a trapezoid: A = 1/2h·(sum of bases)
A = 1/2(6)(8 + 4)
A = 3(12)
A = 36 sq inches
