The answer is, x=11
hope this helps!
The straight arrow at the bottom represents 180 degrees.There 3 x's in eqaution so you divide 180 by 3 and you get 60 degrees
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
Answer:
1. 37.0 in²
2. 55 m²
Step-by-step explanation:
1) all angles in an equilateral triangle are 60°
The dotted line is an angle bisector which also divides the triangle into two congruent right angle triangles
Find the base using trig ratio
cos(30) = 8/base
base = 16sqrt(3)/3
Area = ½ × 16sqrt(3)/3 × 8
= 36.95041723 in²
2. d1: 5 + 5 = 10
d2: 3 + 8 = 11
Area = ½ × 10 × 11
= 55 m²
.25 is the answer because the next number should be half of the previous number and the opposite sign of the previous number.
