Answer:
there are 2 a cute angles in a triangle
Answer:
Perimeter = 34ft Area = 72ft squared
Step-by-step explanation:
The perimeter of an object is all of it's sides combined. Because you stated two values, I assumed your shape is a rectangle. So the perimeter would be:
8 + 8 + 9 + 9 = 34
The area is length times width, so:
8 x 9 = 72
Because it is area, the units are squared.
Answer: She has 76 dimes and 78 quarters.
Step-by-step explanation:
Given data:
Total = $27.20
Solution:
Q = d + 2
Each quarter is 25 cents, or 0.25 of a dollar = 0.25q
Each dime is 10 cents = 0.10d
0.25q+0.10d = $27.20
Where q = d-2
Substitute in this equation:
0.25(d+2)+0.10d = 27.20
0.25d + 0.5 + 0.10d = 27.20
0.35d = 26.7
Divide both sides by 0.35
d = 76
She has 76 dimes and 76 + 2 = 78 quarters.
1st. is definitely 150.
2nd. is a i think
3rd. is 100
