Answer C is correct because 2×(4×305) is the same as (2×4)×305 and 2×4=8.
Answer:
21+j=55
Step-by-step explanation:
It says sum, which means to add(+). So you add 21 and j (21+j) and that equals 55 (=55). Then you add all the pieces together and you get 21+j=55
3/5 = 6/10 (which is 60%) 100% - 60% = 40%
Answer:
The regular polygon that she should use is an equilateral triangle
Step-by-step explanation:
The parameters given are;
Interior angles = 0.5 × Exterior angles
Exterior angles of a regular polygon = 360/n
Sum of interior angles of a regular polygon = (n - 2) × 180
Where n = the number of sides
Therefore, the sum of exterior angles of a regular polygon = 360°
Hence we have;
(n - 2) × 180 = 360/2 = 180
n - 2 = 180/180 = 1
n = 1 + 2 = 3 which is a three sided regular polygon or an equilateral triangle
Therefore, the regular polygon that she should use is an equilateral triangle
Answer:
x = 5.95
Step-by-step explanation:
Given
= 3.5
Multiply both sides by 1.7 to clear the fraction
x = 1.7 × 3.5 = 5.95
