If the dimensions of the following cylinder are tripled, what will be the volume of the new cylinder?
15,260.4 cm
45,781.2 cm
61,041.6 cm
183,124.8 cm
Answer: [tex]45781.2\text{ cm}^3 [/tex]
Step-by-step explanation:
From the given picture, the diameter of the base of cylinder = 12 cm
i.e. the radius of the cylinder =[tex]r=\dfrac{12}{2}=6\ cm[/tex]
Height = 15 cm
If the dimensions of the following cylinder are tripled, then the radius of cylinder =[tex]3\times6=18\ cm[/tex]
Height=[tex]3\times15=45\ cm[/tex]
We know that the volume of a cylinder is given by :-
[tex]\text{Volume}=\pi r^2 h\\\\\Rightarrow\\text{Volume}=(3.14)(18)^2(45)\\\\\Rightarrow\text{Volume}=45781.2\text{ cm}^3 [/tex]
Ice is placed around a bowl of water to lower the temperature. The equation D=−7/5t+22 shows the time, t, measured in minutes and temperature, D, measured in degrees Celsius. Which statement is correct?
a)The temperature of the water decreases 5°C every 7 minutes.
b)The temperature of the water increases 7°C every 5 minutes.
c)The temperature of the ice that is around the bowl is 22°C
d)Before cooling begins, the temperature of the water is 22°C
Answer:
d)Before cooling begins, the temperature of the water is 22°C
Step-by-step explanation:
Given equation that shows the temperature of the bowl after t minutes,
[tex]D=-\frac{7}{5}t+22[/tex]
Initially ( when ice is not placed ) t = 0,
So, the temperature of the water,
[tex]D=(0) + 22 = 22^{\circ}[/tex]
i.e. Option d) is correct.
If t = 7 minutes,
The temperature would be,
[tex]D=-\frac{7}{5}\times 7+22[/tex]
[tex]=-\frac{49}{5}+22[/tex]
[tex]=-\frac{49+110}{5}[/tex]
[tex]=\frac{61}{5}[/tex]
[tex]=12.2^{\circ}C[/tex]
So, the change in temperature = 12.2° - 22° = -9.8°,
Thus, option a) is incorrect.
If x = 5 minutes,
The temperature would be,
[tex]D=-\frac{7}{5}\times 5+22=-7+22 = 15^{\circ}[/tex]
Change in temperature = 15° - 22° = -7°,
So, Option b) is incorrect.
∵ The temperature of the ice must be less than 22°,
Thus, option c) is incorrect.

In softball, a batting average is the number of hits divided by the number of times at bat. Does Eva or Michelle have the higher batting average?
Player Hits At Bats
Eva 42 90
Michelle 38 80
Answer:
Michelle has a higher batting average with 0.475
Step-by-step explanation:
Batting average is equal to the number of hits divided by the number of times at bat:
First, we have to know the batting average of both players:
Eva:
Hits = 42
Times at bat = 90
Now we divide to get the batting average:
42/90 = 0.466
Michelle:
Hits = 38
Times at bat = 80
Now we divide to get the batting average:
38/80 = 0.475
Michelle has a batting average of 0.475 compared to Eva's which is a 0.466, so Michelle's has a higher batting average.

How do I solve 2q+10=7q
Final answer:
To solve the equation 2q + 10 = 7q, subtract 2q from both sides and then divide by 5, resulting in q = 2.
Explanation:
To solve the equation 2q + 10 = 7q, you need to isolate the variable q on one side. Here are the steps you should follow:
Subtract 2q from both sides to get all q terms on one side of the equation: 2q + 10 - 2q = 7q - 2q, which simplifies to 10 = 5q.
Divide both sides by 5 to solve for q: 10 / 5 = 5q / 5, resulting in q = 2.
Therefore, the value of q that solves the equation is 2.
Michael earned $159 mowing lawns all summer. If he mowed 39 lawns, about how much did he make per lawn?
Michael made approximately $4.08 per lawn by dividing the total earnings of $159 by the total number of lawns 39 he mowed.
To find out how much Michael made per lawn, we need to divide the total amount of money he earned by the number of lawns he mowed. Michael earned $159 over the summer and mowed 39 lawns. Therefore, we calculate the earnings per lawn using the following equation:
Earnings per lawn = Total money earned \/ Number of lawns mowed
Earnings per lawn = $159 / 39
Now, let's do the calculation:
Earnings per lawn = $4.0769...
To provide an approximate value, we round the amount to the nearest cent, which gives us an answer of approximately $4.08 per lawn.
m<2=34 find m<4 and explain how you know
Angle 4 equals 34 degrees since angle 2 and 4 are opposite angles and opposite angles are congruent
Given only that m<2 = 34, we can't find the value of m<4. More information about the relationship between these angles is needed to solve the problem.
Explanation:The question asks to find the value of m<4 given that m<2=34.
It's important to note here that 'm<2' and 'm<4' are two different angle measures. Without more information about their relationship, such as them being supplementary, complementary or vertically opposite angles, it's impossible to find the measure of m<4 based on m<2 alone.
So, we can't find the value of m<4 using only the information provided. You might need to look back at the original problem or figure to see if there is additional information available about these angles.

How can area models be used to solve multiplication problems
Area models can be used to solve multiplication problems by visually representing the multiplication as the area of a rectangle or square. The model is divided into equal-sized sections, with the number of sections representing one factor and the size of each section representing the other factor. The total area of the model gives the product of the two factors.

The model is divided into equal-sized sections, with the number of sections representing one factor and the size of each section representing the other factor. The total area of the model gives the product of the two factors. For example, if we have a model representing 4 × 3, we can divide the model into 4 equal sections horizontally and 3 equal sections vertically, and the total area will be 12, which is the product of 4 and 3.
