It's a 45-45-90 triangle,
where the legs are congruent, and the hypotenuse is sqrt(2) times the length of a leg.
Answer: 10%
Step-by-step explanation: The formula to calculate simple interest is Interest = Principal x Rate x Time
With the number in the formula, 112.50 = 1,250 x r x 1
Simplify:
112.50 = 1,250r
Divide both sides by 1,250:
.1 = r
Therefore, the rate is 10%
Answer:
A
Step-by-step explanation:
Six hundred seventy-two thousandths = 0.672
0.672 < 0.8
Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7
Answer:
The distributive property teaches us how to properly multiply in examples like the answer I have given.
In my example : 2 * (4 + 12x) = 8 + 24x
We would take the 2 that is on the outside of the equation in the parenthesis and multiply it first with the 4, and then with the 12x. This results in 8 + 24x.
A simplified version would be to just remove the x.
When we do that we see that 8 + 24 is equal to 32.
What it also demonstrates is that:
2 * (4 + 12) is the same as saying 8 + 24, both equal 32.
