198

Answer:

C

Step-by-step explanation:

The most common number of hours volunteered is 34, so the answer can't be A or D. 7 students volunteered more than 30 hours, while 12 students did less than 30 hours, which means B is incorrect. There are 3 students that volunteered more than 40 hours and 6 that volunteered between 9 and 20 hours, which means C is correct.

Answer:

0.045 m^3

Step-by-step explanation:

0.2 m x 0.15 m x 0.5 m = 0.015 m^3

0.2 m x 0.3 m x 0.5 m = 0.03 m^3

0.045 m^3

Answer:

Square : 320

Semicircle: 32π

Total Area: 320 + 32π

Step-by-step explanation:

The rectangle is 16 x 20 = 320.

We know the semicircle's diameter is 16, so the radius is 8.

the area of a semicircle is \(\frac{1}{2}\pi r^2\)

the radius is 8, we plug that in to get:

\(\frac{1}{2}\pi (8^2)\ = \frac{1}{2}\pi (64) = 32\pi\)

The area of the total shape is 320 + 32π

Answer:

320+32π

Step-by-step explanation:

Let's find the rectangle by multiplying both sides.

16*20=320

Let's find the radius of the semi-circle:

16:2=8

Let's find the area of the circle and divide it by two:

The formula for the area of the circle is πr². r is the radius. Now we can plug in the information we have.

8²*π=64π

64π is the whole circle but we only need half of the circle, so we divide by 2.

64π/2=32π

We can now add the two areas in order to get the area of the full figure.

320+32π

Answer:

$950.51

Step-by-step explanation:

First, find the area of the room, the total square footage, so we know how many tiles to buy. 15*14=210. 210 tiles to buy, $4.25 each. 210*4.25=892.5. If you're not allowed to use a calculator, you can do (210*4)+(210*0.25). The cost before tax is $892.50. What is 6.5% of 892.5? The answer is 58.0125, however, we can't go past the second decimal point or the hundredths digit when deal with money. Rounding to the nearest hundredth, you get $58.01. Add this to cost before tax, 892.50+58.01=950.51. The total cost is $950.51

Answer:

72

Step-by-step explanation:

First, we will multiply the number of posts (7) by the posts' width (6) to get 42.

Since there is a chain between each post, there are 6 chains.

Multiplying the number of chains (6) by the chains' length (5), we get 30.

The question asks us to find the total length of the fence, so we add 42 and 30 and get 72.

Hope this helps!

Hey!!!

Solution,

2x+10+X+5=180 ( sum of co-interior angles)

or, 2x+X+10+5=180

or,3x+15=180

or,3x=180-15

or,3x=165

or, X=165/3

X=55

Hope it helps...

Good luck on your assignment

STAY SAFE......

--------------------------------------------------------

Answer:

Step-by-step explanation:

2x + 10 + x + 5 = 180  (Sum of co-interior angles}

Add the like terms

3x + 15 = 180   {Subtract 15 form both sides}

3x +15 - 15 = 180 - 15

3x = 165  {Divide both sides by 3}

3x/3 = 165/3

x = 55°

Answer:

\(\huge{\left[\begin{array}{cc}94 \text{ percent brown}&6 \text{ percent black}\\42 \text{ percent brown}&58 \text{ percent black}\end{array}\right]}\\ \huge{\text{ which signifies that the black variation}}\\ \text{ was much better suited for survival}\)

Step-by-step explanation:

To solve for percentages, simply divide the given group by the total.

i.e.,

188/200 = 94% of grasshoppers have brown bodies at the start, and

12/200 = 6% of grasshoppers have brown bodies at the start

Then, for the end

147/350 = 42% of grasshoppers have brown bodies at the end, and

203/350 = 58% of grasshoppers have black bodies at the end.

Answer:

y < 1/2x + 8y <

Step-by-step explanation:

y = mx+b
m = slope
b = y - intercept

slope = 1 1/2

y - intercept = 8

Line is dotted so its not equal to

The shade is underneath so its less than.

Answer: 12 yards

Step-by-step explanation:

4 times 3 is 12

The amount of money raised and the number of students who attended the dance will be directly proportional to each other, meaning both are positively dependent on each other. This type of a relationship is called a linear relationship, which can be represented by a type of graphical method called the "linear graph".

To accurately represent the data, on the x axis you need to plot the the number of students attending the dance; and on the y axis you need to plot the amount raised and you'll obtain a positive slope of 10.

The starting point of the graph would have the coordinates (0,100) or x = 0 and y = 100, because even if there are no students attending the event, the decoration cost of 100 dollars would still have to be paid.

The equation for the same should be written as: Amount of money raised = 10 x no. of students + 100

Answer:

Step-by-step explanation:

Im no expert but you would need information on the length and width of the rectangular garden and walkway. To figure this out you would need the information on the width of the walkway and length and width of the rectangle.

Let's pretend a rectangle has a width of 4 and length of 6. I would do 4x6. Then for the walkway lets pretend the width is 3. Since the we know the length of the rectangle is 6 and the width 4, I would do 2(6x3)+2(4x3).

Area = 52x + 5

Step-by-step explanation:

Area = Length × Width

Length = 6.5 ft

Width = 8x+5 ft

Area = 6.5 × (8x+5)

Area = 52x + 5

Answer: Z=14

Step-by-step explanation:

Simplify the equation: 1/4z=7/2

then multiple both sides by 4:

4 (1/4) = 4 (7/2)

z= 14

Answer: z=14

Step-by-step explanation: very easy

1/4z = 3 1/2 Divide each side by 1/4 to isolate z

3 1/2 will be divided by 1/4

How to divide 3 1/2 by 1/4?
Keep, change, flip.

First: Convert 3 1/2 to an improper fraction which is 7/2

Second: 7/2 / 1/4 keep 7/2

7/2 x 1/4 change from dividing to multiplying

7/2 x 4/1 flip 1/4 around to make it 4/1

28/2 multiply and then simplify to 14.

so the answer is 14

Answer:

diameter = 9 inches

radius = 9/2inches

Now, area = pie×r.square

it should be x=log(7)/10*log(2) and x=in(7)/10*in(2)

The required solution for the expression is \(x = ln7/(10*ln2)\).  Option D is correct

To solve \(2800 = 400.2^{10x}\) for x.

The function which is in format f(x) = \(a^x\)  where, a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).  

\(2800 = 400.2^{10x}\)
\(2800/400= 2^{10x}\)
\(7=2^{10x}\)
taking log on both sides.
\(log_27=10x\\x=log_27/10\\x = log_e7/(10*log_e2)\\x =ln7/(ln2*10)\)    
(By properties of logarithm log can be separated to common base e)

The required solution for the expression is \(x = ln7/(10*ln2)\).

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.
