Answer:
106 cm²
Step-by-step explanation:
the surface area is the sum of the areas of the faces of the prism
area of 2 rectangles (left/ right ) = 2 × 7 × 5 = 70 cm²
area of central rectangle = 3 × 7 = 21 cm²
area of 2 congruent triangles = 2 × × 3 × 5 = 3 × 5 = 15 cm²
surface area = 70 + 21 + 15 = 106 cm²
Answer:
3 , 6 , 4
Step-by-step explanation:
Given:
There are three groups of shots in basketball.
First group carry = 1 point
Second group carry = 2 points
Third group carry = 3 points
Sarah scored a total of 25 points by making 13 total baskets.
She made twice as many 2 point shots as she did 3 point shots.
Question asked:
How many of each type of shot did she make ?
Solution:
Let number of baskets, she made which carry 3 points =
Then, number of baskets, she made which carry 2 points =
Total number of baskets, she made = 13
Then, number of baskets, she made which carry 1 points =
Now,
Sarah scored a total number of points = 25
Subtracting both sides by 13
Dividing both sides by 4
By substituting the value:-
Number of baskets, she made which carry 3 points = = 3
Number of baskets, she made which carry 2 points = =
Number of baskets, she made which carry 1 points =
Thus, she made 3 baskets of 3 points, 6 baskets of 2 points and 4 baskets of 1 point.
