Answer:
2571.14 m^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The diameter is 17 so the radius is 1/2 of the diameter or 17/2 =8.5
V = 4/3 (3.14) (8.5)^3
= 2571.13666
Rounding to the nearest hundredth
= 2571.14 m^3
=================================================
Work Shown:
V = (4/3)*pi*r^3
V = (4/3)*3.14*(8.5)^3
V = 2571.13666666667 which is approximate
V = 2571.14
-------------
Notes:
The units for the volume are in cubic meters, or m^3. Think of a 1 m by 1 m by 1 m block, the volume of which is 1*1*1 = 1 m^3.The diameter is 17 meters, half of which is 17/2 = 8.5 meters. So the radius is r = 8.5In the second to last line, the '6's go on forever. It's only due to rounding is why that '7' shows up.The answer above is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate volume. However, your teacher wants you to use pi = 3.145. Find the area of the composite figure *

Answer:
187.5 ft²
Step-by-step explanation:
15 x 15 = 225
1/2(5 x 15) = 37.5
225 - 37.5 = 187.5
Answer:
the area is 187.5
Step-by-step explanation:
First we must split this figure into two, now we have a triangle on top of a rectangle (we know this is a rectangle because the length is longer than the width)
to find the area of a rectangle we must use the equation l*w=A so
15*10=150
Now that we have the area of the rectangle we must find the area of the triangle
We can see one side is longer, this shows us that the triangle is 5 units tall and 15 units long
the formula to find the area of a right triangle is ab/2=A
5*15/2=A
75/2=A
37.5=A
now we have both areas we add them together
37.5+150=187.5
187.5 is your answer
Find the indicated side of the triangle.

During one month, the mean high temperature in Boise, Idaho, was 52.1°F with a standard deviation of 6.5° F. During the same month, the mean high temperature in Death Valley, California, was 81.9° F with a standard deviation of 6.4° F. Select all the statements that are true.
Answers
Answer:
B. The average high temperature in Death Valley was greater than the average in Boise
C. The variation of high temperature in Death valley was about the same as the variation in Boise
Step-by-step explanation:
Step 1: In a normal distribution, about 95% of the values are ±2 standard deviations from the mean. ±2 standard deviation from the mean high temperature of Boise is 39.1 to 65.1. Therefore, option A is wrong
Step 2: The average temperature high temperature of each of the places isngiven by their mean high temperatures.
The mean high temperature in Boise, Idaho, was 52.1°F while the mean high temperature in Death Valley, California, was 81.9°F.
Difference between the mean high temperatures is (81.9 - 52.1) = 29.8°F
Therefore, the average high temperature in Death Valley was greater than the average in Boise. Option B is correct.
Step 3: Standard deviation measures how spread out data is. It is a measure of variation of data.
The standard deviation of the high temperature in Boise, Idaho was 6.5° F, while the standard deviation of the high temperature in Death Valley, California was 6.4° F. This two values are about the same. Therefore, option C is correct.
Step 4: In a normal distribution, about 68% of the values are ±1 standard deviations from the mean. ±1 standard deviation from the mean high temperature of Death Valley is 75.5 to 88.3. Therefore, option D is wrong
Step 5: In a normal distribution, about 99.7% of the values are ±3 standard deviations from the mean. ±3 standard deviation from the mean high temperature of Boise is 32.6 to 71.6. Therefore, option E is wrong

From a horizontal distance of 80 m, the angle of elevation to the top of a flagpole is 18 degree. Calculate the height of the flagpole to the nearest whole meter.
Answers
Answer:
26m
Step-by-step explanation:
The value of the opposite side (height of the flagpole) is to be determined given the angle and the value of the adjacent side(horizontal distance )
We would use tan 18 to determine the value of the missing side
tan 18 = opposite / adjacent
0.3249 = opposite / 80
0.3249 x 80 = 26m

Solve the following system of equations using Substitution, showing all work.
y= 2x + 3
2x + 5y = 3
Answers
Answer: (x,y) = (-1, 1)
This means that x = -1 and y = 1
========================================================
Explanation:
The first equation says that y is the same as 2x+3
That allows us to substitute y for 2x+3 in the second equation like so:
2x+5y = 3
2x+5( y ) = 3
2x + 5(2x+3) = 3 .... y replaced with 2x+3
2x+10x+15 = 3
12x+15 = 3
12x = 3-15
12x = -12
x = -12/12
x = -1
Then we'll substitute this into the first equation to find y
y = 2x+3
y = 2(-1) + 3 .... x replaced with -1
y = -2+3
y = 1
Together x = -1 and y = 1 pair up to form the ordered pair solution (x,y) = (-1,1)
If you were to graph y = 2x+3 and 2x+5y=3 on the same xy grid, then you should see that the two lines intersect at the location (-1,1). This is a visual way to determine the solution quickly through use of a graphing calculator.

Answers
Answer:
El total que la señora Rina pagó por sus frutas, en términos de b, es:
5b - 7Step-by-step explanation:
Para resolver este ejercicio, primero sacaremos las variable que nos brindan:
Costo de la pera = bCosto de la manzana = b - 7 (esto se debe a que la manzana cuesta 7 pesos menos que la pera, tal como dice el enunciado).Ahora, nos centraremos en la compra realizada por la señora Rina, donde se menciona que:
Compra de la señora Rina = 4 peras + 1 manzanaAhora, como si esto fuera una ecuación, vamos a reemplazar las manzanas y las peras por las variables que tenemos de su costo:
Compra de la señora Rina = 4b + b - 7Y procedemos a operar:
Compra de la señora Rina = 5b - 7 (sumando 4b + b)Por lo tanto, la compra de la señora Rina, en términos de b, le ha costado 5b - 7.

The highest common factor of 10 and 18
Answers
Answer:
The highest common factor of 10 and 18 is 2
Step-by-step explanation:
10: 1,10,2,5
18: 1,18,2,9,3,6,
Look which is common in both of these and both of them have 2 in common.
The HCF of 10 and 18 is 2.
To find the highest common factor (HCF) of 10 and 18, we can determine the largest number that divides evenly into both of them.
We can start by listing the factors of each number:
Factors of 10: 1, 2, 5, 10
Factors of 18: 1, 2, 3, 6, 9, 18
From the lists, we can see that the common factors of 10 and 18 are 1 and 2.
To find the HCF, we select the largest common factor, which is 2. Therefore, the HCF of 10 and 18 is 2.
The HCF represents the largest number that divides evenly into both given numbers, without leaving any remainder. In this case, 2 is the highest common factor, as it is the largest number that can divide both 10 and 18 without leaving any remainder.

Q4: If x and y are two supplementary angles whereas m<x=70 then find the m<y.
The sum of two supplementary angles is 180degrees, hence;
m<x + m<y = 180
70 + m<y = 180
m<y = 180 - 70
m<y = 110degrees

Find sec 0, sin 0, and tan 0, where is the angle shown in the figure.
Give exact values, not decimal approximations.
Answers
Answer:
Secθ = 11 / 9.22 or sec33°
Sinθ = 6 / 11 or Sin33°
Tanθ = 6 / 9.22 or Tan33°
θ = 33°
Step-by-step explanation:
Given:
Hypotenuse = 11 unit
Perpendicular = 6 unit
Find:
Secθ
Sinθ
Tanθ
Computation:
Base = √Hypotenuse² - Perpendicular²
Base = √11² - 6²
Base = √121 - 36
Base = √85
Base = 9.22 unit (Approx.)
Secθ = Hypotenuse / Base
Secθ = 11 / 9.22 or sec33°
Sinθ = Perpendicular / Hypotenuse
Sinθ = 6 / 11 or Sin33°
Tanθ = Perpendicular / Base
Tanθ = 6 / 9.22 or Tan33°
So value of θ = 33°

you can see x=6 and y=1.
that is then the point (6,1).
we could also define the equations of both lines and then calculate the value of x, where both equations deliver the same (y) value.
but for that we would need to get the (x,y) coordinates of the 4 marked points in the same way we got them for the crossing point already. waste of time and effort.
