Answer:
A. 34in
Step-by-step explanation:
If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;
P = 2(68.2) = 136.4in
Since the perimeter of a square is expressed as:
P = 4L
136.4 = 4L
L = 136.4/4
L = 34.1in
Hence the measurement of one side of the square poster is closest to 34in
Answer:
1. 109
2. 29
3. 71
Step-by-step explanation:
1. since a triangle's interior angles always add up to 180, you can add 35 and 36 to get 71, then subtract that from 180 to find the third angle
2. the unnamed angle in triangle RUV is supplementary to <1.Supplementary angles are angle the add up to 180. So you can subtract 109 from 180 to find the unnamed angle. It is 71. Now you can repeat the steps in question one to find <2 in triangle RUV. You get that <2 is 29
3. Angle 3 and the unnamed angle are vertical angles. This means that they are opposite to each other and are congruent. This means that they have the same measure. Knowing that the unnamed angle is 71, we can say that angle 3 is also 71.
Answer:
the number is -2/7
Step-by-step explanation:
let the number be x
2x ×4= 7x-2/7
8x = 7x-2/7
collect like terms
8x-7x = -2/7
X= -2/7
