Answer:
The answer is 10 and 10i .
ANSWER
The car moves at 32 mi/hr
EXPLANATION
This question is asking us to determine how fast is a train that makes 330 mile trip in 4 hours.
This is the same as calculating the speed of the train:
Speed = distance covered/time taken
The distance covered is 330 mile
The time taken is 4 hours.
Speed =330/4 =82.5 mi/hr
I don't see an inequality, but I can tell you that the sign of the inequality is flipped whenever you multiply or divide by a negative number.
Answer: 1064 square meters
Step-by-step explanation: area of a triangle is a= 1/2xhxw a=1/2xhx28
h= 76 (90-14)
a=1/2x76x28=1064
The area of the composite solid in the image given is: 399.6 m².
<h3>What is the Surface Area of a Composite Solid?</h3>
The surface are of the composite solid = area of the 3 triangular face of the top solid + area of the triangular base of the bottom solid + 3(area of rectangular face of the bottom solid).
Area of the 3 triangular face of the top solid = 3(1/2bh) = 3(1/2 × 8 × 7) = 84 m²
Area of the triangular base of the bottom solid = 1/2bh = 1/2 × 8 × 6.9 = 27.6 m²
3(area of rectangular face of the bottom solid) = 3(length × width) = 3(12 × 8) = 288 m²
Surface area of the solid = 84 + 27.6 + 288 = 399.6 m²
