Step-by-step explanation:
the area of :
1) inside surface = (3.14× 1.25²)+(3.14×2.5×1.5)
= 4.90625 + 11.775 = 16.68125 m²
2) upper side surface= (3.14 × (1.35²-1.25²))
= 3.14× (1.8225-1.5625)= 3.14×0.26=0.8164m²
3) lateral surface= 3.14×2.7×1.6=13.5648m²
the total amount of vinyl required for the spa =
16.68125+0.8164+13.5648 = 31.06245 m²
Given the vertices of a triangle ABC below, find the midpoint and length of the midsegment. Give your length in simplified radical form.
Answer:
Midpoint of AC = (-1, 1)
Midpoint of BC = (1, -2)
Length of the midsegment = [tex]\sqrt{13}[/tex]
Step-by-step explanation:
Vertices of a triangle ABC are A(0, 5), B(4, -1) and C(-2, -3).
Midpoint of segment AC = [tex]\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}[/tex]
= [tex](\frac{0-2}{2},\frac{5-3}{2})[/tex]
= (-1, 1)
Midpoint of BC = [tex](\frac{4-2}{2},\frac{-1-3}{2})[/tex]
= [tex](1,-2)[/tex]
Length of the mid segment = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
= [tex]\sqrt{(-1-1)^2+(-2-1)^2}[/tex]
= [tex]\sqrt{4+9}[/tex]
= [tex]\sqrt{13}[/tex]

Which of the following formulas is used to find the circumference of a circle?
O A. C = op?
B. C = 23d
O C. C = 8012
O D. C = 281
helpp someoneee
Answer:
D.
Step-by-step explanation:
Circumference of a circle is also referred to as the perimeter bordering the circle.
Thus, it is given as:
C = 2πr
C is circumference
r = half of the diameter of the circle = r
This formula used in finding the circumference of a circle is C = 2πr
The function f(x)=-\x-4/+6 is increasing
through the interval -
A. 6
C. 4
B. -00< x < 4
D. 4
:)
Answer:
Option B
Step-by-step explanation:
Given function is,
f(x) = -|x - 4| + 6
By using a graphing tool we can get the graph of the given function.
From the graph attached slope of the line drawn from [tex]x=-\infty[/tex] to [tex]x=4[/tex] is positive while slope of the line from [tex]x=4[/tex] to [tex]x=\infty[/tex] is negative.
Therefore, segment showing a positive slope will be increasing in the given interval [tex]-\infty<x<4[/tex].
Function 'f' is increasing in the interval [tex]-\infty<x<4[/tex].
Option B will be the correct option.
The topic is about secant tangent angles
Answer:
x = 71
Step-by-step explanation:
The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is
x = [tex]\frac{1}{2}[/tex] (92 + 50) = 0.5 × 142 = 71
John brother Ricky also works part time in the summer. Ricky started working at the same time as John with a. Account balance of $227and deposit $24 each week. Writ an expression for the amount Ricky has in the bank after w week
Answer:
$227 + $24w
Step-by-step explanation:
Initial balance = $227
Amount deposited per week = $24
Amount in account after w weeks
Total amount = initial balance + total weekly deposit
Total Weekly deposit = $24 * number of weeks
Number of weeks = w
Hence,.
Total deposit = $227 + $24w
What is the standard equation of a circle with center (-2,0) and radius 4?
Answer:
B(x+2)^2+y^2=16
Step-by-step explanation:
since you have an x-coordinate only and it is negative and a y coordinate which is 0..basically x will appear positive with its conjecture x^2 and the y value will be independent...y^2...bare in Mind that radius is always squared hence it is 16 instead of 4

Write a division equation and solve (Hint: write the mixed number as an improper fraction): If the host intends to serve each guest at the party 1/5 of a pizza, how many servings can be made with the remaining 2 1/2 pizzas?
Answer:
Step-by-step explanation:
fraction of pizza=5/2
host serves to each guest=1/5*5/2
=5/10
so no of serving that can be done with the remaining 21/2 pizza
5/10-1/5
5*1-1*2/10
5-2/10

what is the value of x
Answer:
20
Step-by-step explanation:
Those angles are the same so you can put them in an equation like this:
x + 60 = 4x
Then you subtract x from both sides to get variables on one side and constants on the other:
60 = 3x
Now divide by three to find what just x is:
20 = x
And there you go <3

Help
Answer:
36 ft
Step-by-step explanation:
Given :
12 yards.We need to convert it into feets. We know that ,
[tex] \implies[/tex] 1 yard = 3 feet
[tex] \implies[/tex] 12 yards = 12 * 3 ft
[tex] \implies[/tex] 12 yards = 36 ft .
Hence the required answer is 36 feets .
Answer:
the formula for converting yards into feet: 1 yard is equal to 3 feet. Write out the necessary math problem or use a calculator. If you want to convert 21 yards, for example, the problem would be 21 multiplied by 3 (21 x 3). Finish the conversion.
SO,
12 yd 36.00 ft

Jorge got a hit 8/25 of the times that he
batted. What percent of the times did
he get a hit?
Answer:
32%
Step-by-step explanation:
Percent means out of 100 so we need the denominator to be 100
8/25 * 4/4 = 32/100
The percent is the numerator since it is now out of 100
32%
Answer: 32%
Step-by-step explanation:

The ages of two groups of karate students are shown in the following dot plots:
A dot plot shows Age in years on the horizontal axis. For Group A, there are 2 dots on 4, 5 dots on 5, 3 dots on 7, 4 dots on 8, 2 dots on 9, 2 dots on 11, and 1 dot on 14. For Group B, there is 1 dot on 7, 2 dots on 8, 1 dot on 9, 1 dot on 11, 1 dot on 16, 2 dots on 19, 2 dots on 20, 2 dots on 21, and 1 dot on 26.
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
Group A has greater variability in the data.
Group A has less variability in the data.
Group B has a lower range.
Group B has a lower mean.
Answer:
Group A has greater variability in the data.
Step-by-step explanation:
We use elimination. Clearly, from the MAD, Group A has greater variability in the data.
So, choice 1.
Rewrite the expression in the form zn.
Answer:
zⁿ = z³
Step-by-step explanation:
We have the expression:
√(z/ z^⅓)
Hence
= z^½/ (z^⅓)^½
= z^½/ (z^⅙)
= z^(½ ÷⅙)
= z ^(1/2 × 6/1)
= z³
Therefore: zⁿ = z³

Wants to wrap a shipping box shaped like a rectangular prism. The box is 25 inches tall and has a square base with sides that each measure 6 inches. How much paper will she use?
Answer:
672 square inches
Step-by-step explanation:
Given data
Height= 25inches
Lenght = 6 inches
Width= 6 inches
The expression for the area of the box is given as
TSA= 2 (lh + lw+ hw)
TSA= 2(6*25+ 6*6+ 25*6)
TSA= 2(150+ 36+150 )
TSA= 2*(336)
TSA= 672 square inches
