Question 4 the answer is 30 degrees.
Question 5 the answer is 132 degrees because angles on a straight line equal to 180 so 180-48.
Question 6: 90+25=115, 180-115=65
Question 7: 180-149= 31
Answer:
1 to 1
Step-by-step explanation:
8 to 8 = 8:8 = 8/8
You can treat a ratio as a fraction. Reduce the fraction 8/8 by dividing the numerator and denominator by 8.
8/8 = 1/1
8 to 8 = 1 to 1
Answer:
uhhhh I don't know how to explain how to graph it
Step-by-step explanation:
Answer:
320in²
Step-by-step explanation:
Labelled diagram shown above.
Surface area : base × height
The surface area of most of the sides will be the same because the sides are the same.
Top/bottom = 5 × 8 = 40 + 40 = 80in²
Side/Side = 5 × 10 = 50 + 50 = 100in²
Front/Back = 8 × 10 = 80 + 80 = 160in²
Add them all together.
160 + 100 + 80 = 340in²
D is 11
2d - 5 = 17 add 5 to both sides
2d = 22 divide by 2
d = 11 answer
