Left on together, the cold and hot water faucets of a certain bathtub take 4 minutes to fill the tub. If it takes the cold water faucet 12 minutes to fill the tub by itself, how long will it take the hot water faucet to fill the tub on its own

Answer:

3.2 miles

Step-by-step explanation:

Given the following question:

Yesterday Janice jogged 2.35 miles
Today Janice jogged 2.45 miles

[tex]2.45+2.35=4.8[/tex]

Janice ran 4.8 miles in total, so if she wants to run approximately eight miles by tomorrow, she needs to run....

[tex]8-4.8=3.2[/tex]

Janice needs to run another 3.2 miles if she wants to run a total of eight miles.

Hope this helps.

Step-by-step explanation:

    2 1/12

Answer: 2 1/12

Answer: 2 an 1/12

Step-by-step explanation:

You can do this 2 ways
1. 6 and 8/12 - 4 and 7/12
--Start by subtracting the wholes.
-6-4=2
--Next subtract the individual fractions
-8/12-7/12= 1/12
-- All together you would get 2 and 1/12
However most questions might not be this easy (the next way will work every time)
2. 6 and 8/12 - 4 and 7/12
--Start by Making the numbers into improper fractions( that means that the number on top is larger than the one on bottom)
-(do this by multiplying the whole (6 or 4) by the denominator (12) then add that number to the numerator of the fraction)

6*12=72  
72/12 + 8/12 = 80/12
6 and 8/12= 80/12

4*12=48
48/12 +7/12 = 55/12
4 and 7/12= 55/12
--Next subtract the new improper fractions
-80/12-55/12= 25/12
-- last convert this improper fraction into a mixed fraction
You do this by seeing how many times the denominator (12) can go into the numerator(25)
12 can go into 25 two times because 12*2=24
This 2 is the whole number

Because 24 is one less than 25 there is 1 left over

This is the numerator of the fraction  2 AND (1/12)

The area of the circle is 36π m² and 9π m².

A circle is the locus of a point such that all set of points are equidistant from a fixed point known as the center.

The area (A) of a circle with a radius r is given by:

A = πr²

For the first circle, the radius is 6m:

A = π(6)² = 36π m²

The second circle has a diameter of 6m, hence the radius is 3m, hence:

A = π(3)² = 9π m²

From the table, the area of the circle is 36π m² and 9π m².

i got it right on Imagine Math.. :)

Step-by-step explanation:

First. plug in values of x and try to form a curve. Since this a quadratic, we will get a parabola( a U shaped graph).

Plug in values from -3 to 4.

for x.

[tex]f( - 3) = 2( - 3) {}^{2} - 3( - 3) - 5 = 22[/tex]

[tex]f( - 2) = 2( - 2) {}^{2} - 3( - 2) - 5 = 9[/tex]

[tex]f( - 1) = 2 + 3 - 5 = 0[/tex]

Keep going until you get until you get to 4 for x.

The graph above should be your curve.

1. The roots of a quadratic are the x values when y=0, here it is 2.5 and -1.

2. Since the leading degree coeffecient is positive, we have a minimum value. It hard to tell the minimum here so let put this in vertex form, we have

[tex] 2{x}^{2} - 3x - 5[/tex]

First. we do

[tex] \frac{ - b}{2a} [/tex]

[tex] \frac{ - ( - 3)}{4} [/tex]

[tex] = \frac{3}{4} [/tex]

Now, we plug that in to find our y intercept of the minimum.

[tex]2( \frac{3}{4} ) {}^{2} - 3( \frac{3}{4} ) - 5 = \frac{18}{16} - \frac{9}{4} - 5 = - \frac{ 18}{16} - 5 = - \frac{98}{16} [/tex]

So we have

(3/4,-98/16).

or

(3/4,-6.125).

[tex]\frac{n^4}{144m^4}[/tex]

Step-by-step explanation:

So here we have our equation: [tex](\frac{3m^-^5n^2}{4m^-^2n^0} )^2*(\frac{mn^4}{9n})^2[/tex]

Begin with separating them both and only focusing on [tex](\frac{3m^-^5n^2}{4m^-^2n^0} )^2[/tex] for now. We have the exponent 2 on the outside of the parenthesis which means everything on the inside will be given this exponent, and with variables that have already been given exponents, you simply multiply those exponents together as basic numbers. Our result will be [tex](\frac{3^2m^-^1^0n^4}{4^2m^-^4n^0} )[/tex], now we're going to deal with those negative exponents, when they're negative you need to switch the side of the fraction they're on, say if it's on the bottom and it is negative that variable alone will be transferred to the top, the same goes with if the negative exponent is on the top, it'll basically be brought down to the denominator position. We now have [tex](\frac{3^2n^4m^4}{4^2n^0m^1^0} )[/tex] all that's left is to solve 3^2, 4^2, and n^0 as anything to the power of 0 will always be 1. And we now have our solution for the first segment; [tex](\frac{9n^4m^4}{16m^1^0} )[/tex] :)

Moving on, now focusing on [tex](\frac{mn^4}{9n})^2[/tex] we once again distribute the power of 2 to each variable, which we receive [tex](\frac{m^2n^8}{9^2n^2})[/tex] from. We have no negative exponents so we can skip the part of this process and now move on to factoring 9^2 which is 81 giving us [tex](\frac{m^2n^8}{81n^2})[/tex]!

Our last step is to multiply [tex](\frac{9n^4m^4}{16m^1^0} )[/tex] and [tex](\frac{m^2n^8}{81n^2})[/tex], I'm super sorry but I haven't even personally gotten this far in my lessons so I can't give the answer from myself but I already spent a whole lot of time thinking I'd be able to finish haha, but the result will be [tex]\frac{n^4}{144m^4}[/tex].

Answer:16a+20

Step-by-step explanation:multiply 4 times 4a in the parentheses. And 4a times 5. Hopefully this helps.

Answer:

B, C, D

Step-by-step explanation:

Use the distributive property. Multiply both terms inside the parentheses by 4.

4(4a + 5) = 4 × 4a + 4 × 5 = 16a + 20

Now let's look at each choice:

A. 16a + 5, not equal to 16a + 20. Incorrect.

B. 16a + 20. Correct.

C. 12a + 20 + 4a = 12a + 4a + 20 = 16a + 20. Correct.

D. 2(8a + 10) = 2 × 8a + 2 × 10 = 16a + 20. Correct.

E. 16a + 5 + 4 = 16a + 9, not equal to 16a + 20. Incorrect.

Answer:

Step-by-step explanation:

Consider -7-4r=-15. Adding 7 on both sides of the equation,

-4r=-8 --- r = 2

Plug in value of r in r/2 + 9 = 2/2+9 = 1+9 = 10

Answer: (3, 3)

Step-by-step explanation:

the graphs of [tex]f[/tex] and [tex]f^{-1[/tex] are flipped: if the point [tex](x, y)[/tex] is on the graph of [tex]f[/tex], then the point [tex](y, x)[/tex] is on the graph of [tex]f^{-1[/tex].

Any points of intersection will satisfy [tex](x, y) = (y, x)[/tex]. A point that satisfies this property must have the same x and y coordinate. (Think about it.) The only point on [tex]f[/tex] like that is [tex](3, 3)[/tex], so that is the point of intersection.
