Answer:
The effect of doubling the diameter is increased the area to paint as 4 times. So, paint needed is 4 times than it was before. And the area is increased by 9 times when the diameter is increased by a factor of 3. So, paint needed is 9 times than before.
Step-by-step explanation:
Please remember the concept
If side lengths are in the ratio a : b
Then the area are in the ratio of a^2 :b^2
The volume are in the ratio of a^3 :b^3,
When diameter is doubled, the area ratio becomes [tex]x^{2} :(2x)^{2}[/tex] which is simplified to [tex]x^{2} :4x^{2}[/tex]
So, the area is increased by 4 times.
According to this concept , the diameter is increased by the scale factor 3.
Let the diameter of tank is 'x', so the diameter becomes "3x"
So, it's area ratio would be [tex]x^{2} :(3x)^{2}[/tex]
If we simplify it we get [tex]x^{2} :9x^{2}[/tex]
We conclude that area to be increased by 9 times.
Contestant and like terms. What do they mean?
Answer:
Step-by-step explanation:
Like Terms: terms that have the same variable raised to the same power. So like 5x plus 5x plus 5. 5x and 5x are like terms.
I'm going to assume you mean Constant instead of contestant so
Constant: Terms without variables
Example: 5x+2x+7
5x and 2x are like terms
7 is a Constant

A caterpillar moves across the grass at a rate of 4 feet every 7 minutes. How fast does the caterpillar move in feet per minute?
Answer:
0.57 feet per minute.
Step-by-step explanation:
If the caterpillar moves 4 feet every 7 minutes, it can be written as a ratio: 4/7. When you divide 4 by 7, you'll find the feet per minute rate.

If f (x)
-3x + 2 and g (2) = x + 1 find g(f(x)) please helppp
[tex]\left \{ {{f(x)=-3x+2} \atop {g(x)=x+1}} \right.[/tex]
To find g(f(x)), Substitute f(x) in g(x).
[tex]g(-3x+2)[/tex]
Then substitute x = -3x+2 in g(x) = x+1
[tex]g(-3x+2)=(-3x+2)+1\\g(-3x+2)=-3x+2+1\\g(-3x+2)=-3x+3[/tex]
Therefore, the answer is [tex]g(f(x))=-3x+3[/tex]

Solve the equation. -0.2(30) + 0.5x = 0.2(30 + x)
Answer:
x=40
Step-by-step explanation:
Use the slope-intercept form to graph the equation y=-8/3x+3
Answer:
See below :)
Step-by-step explanation:
The easiest way to graph this is to find the x-intercept and y-intercept,
y-intercept:
The y-intercept is extremely easy to find as it's just the "b" in "y = mx + b"
If there is no b, it's (0,0). If there is a b, its (0,b)
This is because the y-intercept is where the lines hits the y-axis so we know x must be 0. We can plug in x as 0 to find y:
y = m(0) + b
y = b
In this case, the y-intercept is (0,3) because the b in y = -8/3x + 3
x-intercept:
The x-intercept requires a little more work. It's the same as the y-intercept. The x-intercept is where the lines hits the x-axis so we know y must be 0. The x-intercept is (x,0)
We can use this to plug in y as 0:
0 = mx + b
mx = -b
Now we use this to find the the x-intercept:
0 = -8/3x + 3
8/3x = 3
Divide both sides by 8/3:
x = 3 * 3/8
x = 9/8
In this case, the x-intercept is (9/8,0)
Now we can use these points and connect a line to them and then the lines keeps going forever. Look at the picture I uploaded :)

the second one
Answer:
area of a square
Step-by-step explanation:
area is found by multiplying length times width. perimeter is found by adding. the area of a triangle wouldn't work because in order to find that, you would need to multiply by all three sides.

Step-by-step explanation:
Tamara has a cell phone plan that charges $0.07 per minute plus a monthly fee of $19.00. She budgets $29.50 per month for total cell phone expenses. What is the maximum number of minutes Tamara could use her phone each month in order to stay within her budget?
Answer:
525 minutes
Step-by-step explanation:
Given that the monthly fee for the phone is $19 and the call charges rate is $0.02 per minute.
Her monthly budget is $29.50.
Let Tamara can make a maximum number of n minutes call in a month.
So, call charges for n minutes = $0.02n
Total monthly expenses on her phone = 19+0.02n
As her monthly budget is $29.50.
So, 19+0.02n=29.50
0.02n=29.50-19
0.02n=10.50
n=10.50/0.02
n=525
Hence, she can make a maximum of 525 minutes call.
