To solve this problem you must apply the proccedure shown below:
1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle <span>if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into </span>A'=3bh/4, you obtain:
<span>
A'=186 units</span>²
<span>
The answer is: </span>186 units²
Answer:
-23.3
Step-by-step explanation:
Given:
a = 3, b = -2, c = 5. 1
Equation;
2a + 3b - 3c + 4b
Find:
Solution
Computation:
2a + 3b - 3c + 4b
2(3) + 3(-2) - 3(5.1) + 4(-2)
6 - 6 - 15.3 - 8
-23.3
Answer:
2 2/3 - 1 3/4 = 11/12
Step-by-step explanation:
You could convert them both to improper fractions then you would make them have common denominators so the least common denominator for the would be 12 so you would multiply them and then you would subtract them to get your answer of 11/12.
2 2/3 = 8/3 times 4 = 32/12
1 3/4 = 7/4 times 3 = 21/12
32/12 - 21/12 = 11/12
First of all how you ain’t get this & it’s left
The answer is 2:1 because at first your ratio would be 18:9 but if you divide that by 9 (for simplifying purposes) than its 2:1
