Find the area of a triangle with the following sides
Step-by-step explanation:
step 1. The easiest way is to use Herons formula.
step 2. s = (a + b + c)/2 = (3 + 5 + 6)/2 = 7
step 3. A = sqrt(7(7-4)(7-5)(7-6))
step 4. A = sqrt(7(3)(2)(1))
step 5. A = sqrt(42)
step 6. A = 6.4807 = 6.5cm^2.
Simplify: 10(48 1/4)-3(3 1/4)
Answer:
472.75 or 472 3/4
Step-by-step explanation:
10(48 1/4)-3(3 1/4) =
10(48.25) - 3(3.25) =
482.5 - 9.75 =
472.75
In fraction form, this is 472 3/4

(25-a) divided by 7=3
Answer:
a = -0.57
rounded to the nearest tenth: a = -0.6
Step-by-step explanation:
(25 - a) ÷ 7 = 3
25 - a ÷ 7 = 3
25 ÷ 7 - a = 3
3.6 - a = 3
3.57 - 3.57 - a = 3 - 3.57
a = -0.57
The value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.
To find the value of "a" in the equation (25 - a) ÷ 7 = 3.
we can solve for "a" by isolating it on one side of the equation.
(25 - a)/7 = 3.
Multiply both sides of the equation by 7 to get rid of the division:
7(25 - a)/7 = 3 × 7.
25 - a = 21.
To isolate "a," subtract 25 from both sides of the equation:
25 - a - 25 = 21 - 25.
Simplifying further, we get:
-a = -4.
Multiply both sides of the equation by -1 to solve for "a":
-1 × (-a) = -1× (-4).
a = 4.
Therefore, the value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.
