Answer:
The correct answer is second option
380 square feet
Step-by-step explanation:
Area of composite solid = Base area + area of side rectangles + area of triangles
<u>To find the area of base</u>
Base area = length * width
= 10 * 10 = 100 ft²
<u>To find the area of side rectangle</u>
There are 4 rectangles with length 10 ft and width 6 ft
Area = 4 * area of one rectangle
= 4 * (10 * 6)
= 240 ft²
<u>To find the area of triangle</u>
Here base of triangle = 10 ft and height = 7 ft
Area of 4 triangles =4 * area of single triangle = 4 * (bh)/2
= 4 *(10 * 7)/2 = 140 ft²
To find the total area = Base area + area of side rectangles + area of triangles
= 100 + 240 + 140
= 380 square feet
The correct answer is second option
380 square feet
Answer:
The population is expected to grow by the function p(t)=50e.85t, where t is in years.a) What will be the population in 2015?
Step-by-step explanation:
First you have to find the number of fish per boat.
600 divided by 15 is 40.
then you multiply 40 by 7 to find how many fish for 7 boats.
40 x 7= 280.
280 fish if they use 7 boats.
Answer: He made $90 last week.
Assumption :
Let, Luis made $X last week.
He made $72 this week which is 80% of $X that he made last week
⇒ X * 80% = 72
⇒ X * 80/100 = 72
⇒ X = (72 * 100)/80
⇒ X = 90
Therefore, he made $90 last week.
To remember :
While solving this type of problems, be careful to understand which one of last time and current time is not given; just assume that one and input other conditions, the problem will be solved.
