3: 240 cm2

Answers
Answer:
4: 20 cm3
Step-by-step explanation:
6 x 4 = 24
24 x 10 = 240
it is cubic since it is volume
Answer: 6
Step-by-step explanation:
4 x 6 = 24
24 x 10 = 240
So the total volume is 240, but without the units it could mean anything. 240 inches or cows, so we have to add cm, but this number could also mean any measurement of centimeters, length, area, perimeter, so we add the 3 to get
240cm3
the 3 is the symbol for cubed, meaning it's measuring the volume of a three dimensional area.

3. Anayah is playing a game. She started with 10 points. In the first round she
lost 20 points. In the second round she won 45 points. Which of the
following shows the changes in Anayah scores?
a) 10 - 20 +45
b) 10 - 20 – 45
c) -10 - 20 + 45
d) -10 – 20 - 45
Answers
Answer:
A.
Step-by-step explanation:
It's set up exactly as it is said. She starts with 10 points automatically so you would put:
10
Then it says that she lost 20 points. Losing is subtraction. You would add this to the equation:
10-20
Then it says she won 45 points. Winning is addition. You would add this to the equation:
10-20+45
This equation matches up with A. thus A. being the correct answer. If they ask for the answer, it is 35 by the way. Hope this helps!
a) 10 - 20 +45
Step-by-step explanation:
Is known :
She started with 10 points.
In the first round she lost 20 points.
In the second round she won 45 points.
Asked :

The speed of a bus weighing 2000 kg increases from 50 mls to 60 m/s in 4 s. Calculate the change in its momentum and the Force applied on it
Answers
Answer:
Momentum = 20 000 kgm/s
Force applied = 5000 N
Step-by-step explanation:
Momentum = Mass * Velocity
= 2000 kg * 10 m/s
= 20 000 kgm/s
Force = Mass * Acceleration
Acceleration = v - u / t
= 60-50/4
= 10/4
= 2.5 m/s^2
F = m*a
= 2000 * 2.5
= 5 000 N

3) 78°
4) 33°
Answers
9514 1404 393
Answer:
3) 78°
Step-by-step explanation:
Let x represent the angle. Then 180-x is its supplement, and the difference is ...
(180 -x) -x = 24
90 -x = 12 . . . . . . . divide by 2
x = 90 -12 = 78 . . . . degrees
The measure of the angle is 78°.

Susanne runs a bakery. Five years ago the bakery sold 224 loaves of bread each day. Today they sell 329 loaves each day. What percent of increase in the number of loaves sold each day?
The percent of increase is %
(type a whole number or a decimal)
Answers
224-329/224=
46.875% increase
Answer:
46.875% - (rounded answers shown below)
Step-by-step explanation:
Percent increase can be calculated by this formula:
(new-original)/original * 100.
In this problem, the 'new' value is 329 because it is the large value and is the more recent out of the two values. Therefore, the 'original' value is 224, because it is the value that is less recent than 329.
So, plugging this into the formula, (329-224)/224. This becomes 105/224, which is 0.46875. We multiply this by 100, and the value then becomes 46.875.
If you want to round this percent, it becomes 47% (whole number) or 46.9% (decimal rounded to the nearest tenth)

Using the mean concept, it is found that the mean of the distribution is of 0.64.
The mean of a probability distribution is given by the sum of each outcome multiplied by it's probability.
In this problem, the probability of each outcome is given by:
[tex]P(X = 0) = 0.513[/tex]
[tex]P(X = 1) = 0.357[/tex]
[tex]P(X = 2) = 0.109[/tex]
[tex]P(X = 3) = 0.019[/tex]
[tex]P(X = 4) = 0.002[/tex]
The, the mean is:
[tex]E(X) = 0.513(0) + 0.357(1) + 0.109(2) + 0.019(3) + 0.002(4) = 0.64[/tex]
The mean of this distribution is 0.64.

5x -4y = 76
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For the given point and slope, this equation is ...
y -(-9) = 5/4(x -8)
Multiplying by 4 gives ...
4y +36 = 5x -40
Subttracting 4y and adding 40 puts this into the desired form.
5x -4y = 76
