Answer:
3.75 is a decimal and 375/100 or 375% is the percentage for 15/4.
Step-by-step explanation:
AB = √(8^2 + 6^2)
AB = √100
AB = 10
AC = √(8^2 + 15^2)
AC = √289
AC = 17
BC = 9
P= AB + AC + BC
P = 10 + 17 + 9
P = 36 units
34)
Area of ABC = 1/2 x 8 x 9
A = 36 square units
Answer:
15,600 meters
Step-by-step explanation:
there are 3600 seconds in an hour. if you divide that by 15 you get 240. multiply 65 by 240 (which is every 15 seconds) and you get 15,600
Answer:
B
Step-by-step explanation:
The first step of any problem solution is <em>look at the given information</em>. Here, we are given the equation of a line in (almost) standard form, and we want to match the equation with a graph. We notice that the coefficients of the variables are factors of the constant, so the intercepts are integer values easily found.
We can compare the line's intercepts to those shown on the graphs to choose the correct graph.
<u>x-intercept</u>
The x-intercept is found by setting y=0 and solving for x:
-3x +5(0) = -15
x = -15/-3 = 5
Only one graph shows a line with an x-intercept of (5, 0): graph B.
<u>y-intercept</u>
We can confirm graph B by finding the y-intercept. For this, we set x=0 and solve for y.
-3(0) +5y = -15
y = -15/5 = -3
Graph B also has a y-intercept of (0, -3), confirming it is the correct choice.

<em>Additional comment</em>
Part of "look at the given information" is "look at the answer choices." What you look for is <em>what makes one choice different from the others</em>. Here, the lines have x- and y-intercepts of ±3 and ±5. The y-intercepts are the same for graphs A and B, and for graphs C and D.
However, the x-intercepts are different for all of them. This tells you that finding the x-intercept is the fastest way to find the correct graph.
Multiply it by 1/4 because the dimensions are already 1/4
