The awnser is D to your question
Answer: I can only see the big boxes so will answer them
5/6 - 1/3
Multiply the two denominators together get 18
Then multiply the bottom denominator with the opposite numerator
The sum has now changed to:
15/18 - 6/18
15 - 6 = 9
9/18 can then be simplified to 1/2
Answer:
Sasha's grandma will need 48 square feet of fabric to sew the umbrella.
Step-by-step explanation:
Since Sasha's grandma is going to sew an umbrella for Sasha, which will be made of 4 identical triangles, if each triangle is 3 feet long and 4 feet high, to determine how many square feet of fabric does Sasha's grandma need, the following calculation must be done:
(3 x 4) x 4 = X
12 x 4 = X
48 = X
Therefore, Sasha's grandma will need 48 square feet of fabric to sew the umbrella.
Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees
