Answer:
37,000 milliliters = 37 liters
Step-by-step explanation:
A Litre is a
1,000
unit greater than a milliliter, so
multiply
the number of liters by
1,000
to find the number of milliliter. Therefore, 37 liters is equal to
37,000

The survey included 80 students. How many students chose bananas?
Answer:
20 Students chose bananas.
Step-by-step explanation:
You can see that the bananas take up 25% or 1/4 of the chart. To find 1/4 of a number find half of the number twice. Half of 80 is 40 and half of 40 is 20. So, 20 students chose bananas.
y + 6 = 5(x – 4)
Write a formula fpr f(x) in terms of x.
Answer:
f(x) = 5x - 26
Step-by-step explanation:
y + 6 = 5(x - 4) ← distribute parenthesis by 5
y + 6 = 5x - 20 ( subtract 6 from both sides )
y = 5x - 26
Now y = f(x) , then
f(x) = 5x - 26
Answer:
f(x) = 5x - 26
Step-by-step explanation:
y + 6 = 5(x – 4)
Distribute
y +6 = 5x - 20
Solve for y
y +6-6 = 5x-20+-6
y = 5x - 26
Replace y with f(x)
f(x) = 5x - 26

Find the value of for X
(Show working out)
Answer:
[tex]x = \frac{11}{2}[/tex]
Step-by-step explanation:
4+2 (x-1)=13
⇒ 2 (x - 1) = 13 - 4
⇒ 2 (x - 1) = 9
⇒ 2 x - 2 = 9
⇒ 2 x = 9 + 2
⇒ 2 x = 11

3. What is the surface area of this composite solid? Show your work.
5 ft
5 ft
3 ft
4 ft
10 ft
8 ft
By finding the area of the simpler parts, we will see that the total surface area of the figure is 348 ft^2
How we do get the surface area?
We can divide this in smaller parts. First, remember that for a triangle of base b and height h, the area is:
A = b*h/2
Then for each of the triangles in the image, the area is:
A = 8ft*3ft/2 = 12 ft^2
And we have two of these.
Then we have the base, a rectangle of 8ft by 10ft, with an area:
A' = 8ft*10ft = 80ft^2
Then we have the front and back sides, rectangles of 8ft by 4ft, with an area:
A'' = 8ft*4ft = 32 ft^2 (we have two of these).
Then the lateral sides, rectangles of 10ft by 4ft, with an area:
A''' = 10ft*4ft = 40ft^2 (we have two of these)
Finally, we have the top rectangles, of 5ft by 10ft, each with an area:
A'''' = 5ft*10ft = 50ft^2 (we have two of these).
Adding all the areas, we get:
Area = 2*(12 ft^2 + 32 ft^2 + 40ft^2 + 50ft^2) + 80ft^2 = 348 ft^2

Divide the solid into 2 cones.
SA of a cone
= πrl
l of cone 1
l² = r² + h²
l² = 9² + 12²
l² = 81 + 144
l² = 225
l = √225
l = 15cm
SA of cone 1
= πrl
= π × 9 × 15
= π × 135
= 135π
l of cone 2
l² = r² + h²
l² = 9² + 40²
l² = 81 + 1600
l² = 16081
l² = 126cm
SA of cone 2
= πrl
= π × 9 × 126
= π × 1134
= 1134π
SA of solid
= 135π + 1134π
= 1269π

The baseball diamond at a playground is a square with sides that measure 70 feet. About how long would a straight line be from home plate to second base? Round your answer to the nearest tenth.
A baseball diamond represented by a square oriented so that the diagonal of the square running from home plate to 2nd base is vertical.
70 feet
140 feet
9,800 feet
99 feet
Answer:
70 if you walk directly across, 140 if you're running the bases
Step-by-step explanation:
So, if the distance between one is 70, than from home>first>second is 140 feet. Because it is a square, if you travel across the field from home directly to second, it is half that distance and only 70.
Andy is building a model train. A train in real life has a wheel diameter of 33 inches, a length of 20 feet, a width of 10 feet, and a height of 12 feet. If his model has a width of 8 inches, what does the height need to be?
A) 0.96 inches
B) 9.6 inches
C) 16 inches
D) 48 inches
Answer: B) 9.6 inches
Step-by-step explanation:
We will set up a proportion to solve. I will have the width of the model (in inches) as my numerator, and the height of the model (in inches) as the denominator.
-> To convert feet into inches, we multiply by 12.
[tex]\displaystyle \frac{120}{144} = \frac{8}{x}[/tex]
Cross multiply:
120 * x = 144 * 8
120x = 1,152

x = 9.6
9.6 inches
The height should be B) 9.6 inches.

A local weather enthusiast wants to see if the last five summers have been warmer than normal for eloy, arizona. from the national oceanic and atmospheric administration (noaa), he knows the 30-year average for july was 90° with a standard deviation of 2.1°. the last five summers recorded have an average of 93.5°. if he uses a = 5%, which of the following would be valid based on the data he has gathered? he can conclude that the summers have been warmer than the 30-year average. he can conclude that the summers will continue to be warmer for the next 10 years. he does not have enough information to make a decision. the average for the last five years fits with the 30-year average.
For the local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of a population
N = number of observations of population
X = mean
μ = population mean
The 30-year average for July was 90°. The standard deviation for this average is 2.1°. Thus, the temperature lies in the range around of 90° in July.
Therefore, the range of the temperature is,
t = 90 - 2.1 = 87.9
t = 90 + 2.1 = 92.1
The last five summers recorded have an average of 93. 5° and the value of a is 5%. Thus, the reduction is,
t = 92 - (92 x 2.5/100)
t = 89.70
This value of temperature lies in the range of 87.9-92.1 degrees Celsius. Hence, the two averages are probably the same.
Hence, for the local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average. Option D is correct.

at $26.76 per share. What is the total cost of the stocks including the commission?
Dan Hostetler purchases 2,000 shares of Ballon Synergy stock at $4.10 per share. Thus, The total cost of stock including the commission is $15917.
What are stocks?Stocks are types of security to shareholders that represent fractional ownership of equity in any organization.
Dan Hostetler purchases 2,000 shares of Ballon Synergy stock at $4.10 per share. He also purchased 500 shares of Matell Scientific at $26.76 per share.
We have a number of shares at $44.41 per share = 100
Number of shares at $19.08 per share = 600
Total number of shares = 700
Broker's charges per share = $0.04
Hence, The total cost of the stock including the commission
= Cost of stock + commission
= (100 × 44.41) + (600 × 19.08) + (700 × 0.04)
= 15,917
Thus, the total cost of stock including the commission is $15917.

You want the average round-trip speed if the speed to London was 480 mph and the return trip to Boston was 600 mph.
SpeedThe average speed will be the total distance divided by the total time. The time is found by dividing the distance by the speed.
If the distance is d, the total time in hours is ...
d/480 +d/600 = (3/800)d . . . . . hours
Then the average speed is ...
2d/(3/800d) = 1600/3 ≈ 533.3 . . . . miles per hour
