The answer is C I just finished taking the test
Answer:
12 square feet
Step-by-step explanation:
To find the area of a triangle you have to multiply the base and height and divide it by two
6 * 4 = 24
24 / 2 = 12
Answer:
c
Step-by-step explanation:
1. We can asume that a = 2, b = 4. Then solve and find which option matches with the answer.
2. Equation itself plugged in with a = 2, and b = 4. 2^2 + 2 x 2 x 4 + 4^2 = 36 / (2 + 4)^3
3. 36 / 216 = 1/6
Find any option that matches your answer and plug in a for 2 and b for 4.
a. a + b = 2 + 4 = 6 - No doesn’t match 1/6
b. a^2 + b^2 = 2^2 + 4^2 = 4 + 16 = 20 - No doesn’t match 1/6
c. 1 / a + b = 1 / 2 + 4 = 1/6 - Yes does match 1/6
d. 1 / (a + b)^2 = 1 / (2 + 4)^2 = 1/36 - No doesn’t match 1/6
Answer:
$22.20
Step-by-step explanation:
We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.
Let's set up our equation by making 13.32 into a fraction.
13.32/x
We will represent the present's actual cost with the letter x.
13.32/x = 3/5
We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a <em>fraction </em>of the present's cost, not the whole cost.
We solve this by doing cross multiplication. Multiply the 13.32 by the 5.
13.32 x 5 = 66.6
Next we divide 66.6 by 3 to get 22.2
66.6/3 = 22.2
This gives us our final answer of $22.20. This means that the cost of the original present was $22.20
