La respuesta es:

Un dia - 2/5 del dia - 1/74 del dia - 3/7 del dia.

= 1 - (2/5) - (1/74) - (3/7)

= $${\mathtt{1}}{\mathtt{\,-\,}}\left({\frac{{\mathtt{2}}}{{\mathtt{5}}}}\right){\mathtt{\,-\,}}\left({\frac{{\mathtt{1}}}{{\mathtt{74}}}}\right){\mathtt{\,-\,}}\left({\frac{{\mathtt{3}}}{{\mathtt{7}}}}\right) = {\frac{{\mathtt{409}}}{{\mathtt{2\,590}}}} = {\mathtt{0.157\: \!915\: \!057\: \!915\: \!057\: \!9}}$$ del dia.

Por lo tanto, es (409/2590) del dia.

En horas, es:

= $$\left({\frac{{\mathtt{409}}}{{\mathtt{2\,590}}}}\right){\mathtt{\,\times\,}}{\mathtt{24}} = {\frac{{\mathtt{4\,908}}}{{\mathtt{1\,295}}}} = {\mathtt{3.789\: \!961\: \!389\: \!961\: \!39}}$$

~ 3.8 horas.

Los metros ella utilizó son:

(3/5) * 80

= 48 metros.

You are very welcome, DragonSlayer554. Good luck in math and in life:)

Since you want to convert that number to square feet, Anonymous, I'm assuming you meant 37200 square inches.

You would divide 37200 by 144, since 1 foot equals 12 inches. 1 square foot would equal (12*12) square inches, or 144 square inches.

So $${\frac{{\mathtt{37\,200}}}{{\mathtt{144}}}} = {\frac{{\mathtt{775}}}{{\mathtt{3}}}} = {\mathtt{258.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

It would be 258 and one-third square feet.

First. write this scenario into an inequality:

x/-6 > 3

Now multiply both sides by -6.

x < 3 * -6

(The inequality symbol is flipped because you are dividing by a negative number).

x < -18, so it would be the third choice.

To check, you can plug in a number less than -18 for x, such as -19.

$${\mathtt{\,-\,}}{\frac{{\mathtt{19}}}{-{\mathtt{6}}}} = {\frac{{\mathtt{19}}}{{\mathtt{6}}}} = {\mathtt{3.166\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

3.16666... is greater than 3, so the answer is correct.

Hello Anonymous,

To 'match each equation with its solution", you would need to solve each equation. First, write each term as an equation.  So here we go:

1st equation:  g/3 + 4 = 2

Subtract 4.

g/3 = -2

Divide by 3.

g = -6, so the first term would match to B.

2nd equation:  11 - u = -7

Subtract 11.

-u = -18

Divide by -1.

u = 18, so the second term matches to C.

3rd equation: y/2 - 7 = -13

Add 7.

y/2 = -6

Multiply by 2.

y = -12, so the third term matches D.

Now you can use the process of elimination to find that the fourth term matches A, but you can also work it out:

4th equation: 2n - 5 = 1

Add 5.

2n = 6

Divide by 2.

n = 3

Hello Alan:) Perhaps Anonymous reposted, but I didn't see any pictures with the question . . . just the question and four answer choices.

And thanks, Ninja!

It depends on what information you have on the cone.

If you know the volume of the cone as well as its height, you could use the formula for the volume of a cone to find the radius, multiply that by 2, and find the diameter.

The formula is: $${\mathtt{V}} = \left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}$$ (the volume equals one-third times pi times the radius squared, times height.)

If you have the area or circumference of the cone's base, use the formulas for area and circumference of a circle.

Circumference: $${\mathtt{C}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{d}}$$

Area: $${\mathtt{A}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}$$

Since Beth added 11.2 gallons of gasoline to fill her tank to 18 gallons, this is the total gas in the tank.

The total gas (18 gal) would equal the 11.2 gallons she added plus the original amount of gas in the tank. The total amount of gas she ends up with in the tank would be whatever amount it held earlier, plus the amount of gas she added (choice 2).
