First add all the numbers together. Then add all the 90 and above answers together. Make a fraction of the 90s and above over the total. then divide the numerator by the denominator.
Answer:
20in²
Step-by-step explanation:
The area of a triangle is calculated using the formula A = bh/2
"A" means area.
"b" is for the base.
"h" is for the height.
It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.
5in can be the height.
8in can be the base.
Put the base and height measurements into the formula.
A = bh/2
A = (8in)(5in)/2 Multiply the measurements and the units.
A = (40in²)/2 Divide by 2
A = 20in² Area of the triangle
When you multiply units, in X in becomes in².
"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.
in¹ X in¹ = in¹⁺¹ = in²
<span>A number divided by 5 is 3 more than –6.
Let the number be "x".
x/5 = -6 + 3
First combine like terms.
x/5 = -3
Now multiply both sides by 5 to get x on one side.
x = -15
The answer is
C. -15

Answer:
C
Step-by-step explanation:
Since they are pythagorian triplets, ABC is a right angled triangle at the angle between the arc 3 and arc 4. Theta is the angle opposite to 3 and hence tan(theta)=3/4
Answer:
21 drawings
Step-by-step explanation:
7 divided by 1/3
when dividing fractions multiply by the reciprocal
7/1 x 3/1 = 21/1
