This question was answered but no solution was given.
We already solve for the B or area of the triangular base which was 5.25cm².
There are 2 triangular faces in the prism so 5.25cm² x 2 = 10.50cm²
There are 3 rectangular face in the prism, we need to get the area of each.
area of a rectangle = length x width
rectangle 1: 5 cm x 4 cm = 20 cm²
same dimension with rectangle 2. so, area is 20 cm² also
rectangle 3: 5 cm x 2.8 cm = 14 cm²
let us all add up the area of each surface.
2 triangle = 10.50 cm²
3 rectangles = 20 cm² + 20 cm² + 14 cm² = 54 cm²
10.50 cm² + 54 cm² = 64.50 cm²
Answer: 0.25 feet
Step-by-step explanation:
Given: Jonathon has paper strips that are all equal in length.
Let x be the length of each paper strip.
Since John lines them up end to end, the length of the line of paper strips= 3 feet
Also total strips used= 12
Therefore, length of line of strips=
hence, if Jonathan is correct then the length of each strip will be 0.25 feet.
I have done this question yesterday it is 1 and 3
<h2>
Answer:</h2>
The the number of students who sign up for all three clubs = 6
<h2>
Step-by-step explanation:</h2>
The total number of students in the class is given by:
Total number of students= Number of students in poetry club+Number of students in history club+Number of students in writing club-Number of students in exactly 2 clubs-2×Number of students in all the three clubs.
Based on the information we have:
Total number of students= 59
Number of students in poetry club= 22
Number of students in history club= 27
Number of students in writing club= 28
and number of students in exactly two clubs=6
Let the number of students in the three club= x
Hence, we have:
59=22+27+28-6-2x
i.e.
59=71-2x
i.e.
2x=71-59
i.e.
2x=12
i.e.
x=6
Hence, the answer is: 6
