Area is 6s^2 and that’s one side: a cube has 6 sides so the surface area is 6(6s^2) = 36s^2 cm

Select the equation that contains the point (3, -9), and in which the graph of the line has a positive slope.

Kamila [148]

First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).

I need an answer what is 1.03 ÷ (-10.3)=?

Sloan [31]

The answer is $- \frac{1}{10}$
To figure this out, convert both numbers to fractions. 1.03 = 1 $\frac{3}{100}$ and (-10.3) = -10 $\frac{3}{10}$ . Now, convert to improper fractions.
1 $\frac{3}{100} = [tex] \frac{103}{100}$
-10 $\frac{3}{10}$ = $- \frac{103}{10}$
Now, divide. Dividing fractions is the same as multiplying by the reciporical. So:
$-\frac{103}{10} \ becomes\ \frac{10}{103}$
$\frac{103}{100} *- \frac{10}{103} = -\frac{1030}{10300} = - \frac{1}{10}$

If 2 cups of ketchup= 1 cup of tomato sauce, then ____ cups of ketchup= 2.25 cups of tomato sauce.

SashulF [63]

We have an equation: 2/1= ?/2.25

Cross multiply:
1*?= 2*2.25
⇒ ?= 2*2.25= 4.5

The final answer is 4.5~
