Lets LA lateral area and SA surface area, b base and l slant height, h the height:
LA= 3(1/2 b l)= 3/2 (10)(8)= 120 cm²
SA= 1/2 bh+3/2 bl
SA=1/2 (8.66)(10)+120cm²= 163.3 cm²
Answer: 79.2
Explanation: 110% as a decimal is 1.10
1.10 x 72=79.2
Answer:
h = 8.78
Step-by-step explanation:
Remark
Since this is a right angle triangle, you could find the area 2 different ways.
Area 1. Use the arms of the right angle to find the area.
Area = 1/2 * a * b
a = 9
b = 40
Area = 1/2 40 * 9
Area = 180 m^2
The other way is to multiply the height by the hypotenuse
h = ?
hypotenuse = 41
Area = 1/2 * 41 * h
But we already know the area
1/2 41 * h = 180 Multiply by 2
41 * h = 2 * 180
41 * h = 360 Divide by 41
h = 360 / 41
h = 8.78
Answer:
Evening walk is shorter.
Step-by-step explanation:
We have been given that a nature center offers 2 guided walks. The morning walk is two-third mile. The evening walk is three-sixths mile. We are asked to find the shorter walk.
Let us compare both fractions by making the same denominator.
Upon making common denominator, we can see that two-thirds are equal to four sixths.
Since three-sixths is less than four-sixths, therefore, evening walk is shorter.
We will draw two rectangles, one with 6 sub-parts and other with three sub-parts.
We will shade 2 parts out of 3 sub-parts to represent 2/3 and shade 3 parts out of 6 sub-parts to represent 3/6.
Then we will further divide three sub-parts into 6 sub-parts as shown in the diagram that will represent 4/6.
