Answer:
9
Step-by-step explanation:
How I got my answer:
a+ bc turns into 7 + 4 x 1/2
First, you do 4 x 1/2 which equals 2 ( 4/1 x 1/2 = 2)
Then, you add 7 and 2
=9
Answer:
reason A
Step-by-step explanation:
AB and AC both are the radii of the first circle
AB=AC
also AB and BC both are the radii of the second circle
hence
AB=BC
By using transitive property
AB=AC and AB=BC
so AC=BC
Therefore reason A "AB and AC are the radii of the same circle and AB and BC are the radii of the same circle so AB=AC and AB=BC and AC=BC" !
The answer to that question is 24
Answer:
$ 1.2 and $ 0.7
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x is the value of clif bars
let y is the value of an apple
Thus:
4 * x + 2 * y = 6.2
5 * x + 3 * y = 8.1 => x = (8.1 - 3 * y) / 5
replacing, we are left with:
4 * ((8.1 - 3 * y) / 5) + 2 * y = 6.2
6.48 - 2.4 * y + 2 * y = 6.2
2.4 * y - 2 * y = 6.48 - 6.2
0.4 * y = 0.28
y = 0.28 / 0.4
y = 0.7
Now to calculate x:
x = (8.1 - 3 * 0.7) / 5
x = 1.2
So the value of clif bars is $ 1.2 and the value of an apple is $ 0.7
Answer:
70%
Step-by-step explanation:
Well, you have 3 hours to work with, which is 180 minutes. You subtract 30 minutes from warm up, then subtract another 24 minutes for group work time, and you're left with 126 minutes. Now, to figure out the percent, you take 126 divided by the total time (3 hours or 180 minutes)
126 / 180 is 0.70, which as a percent is 70%.
