Answer:
Step-by-step explanation:
A=1/2b *h
base(b)= 5/3x
height(h) = h
1/2(5/3x)*x=
5/6x*x=
5/6x^2
Answer: see graphs
<u>Step-by-step explanation:</u>
start at the origin and draw an arrow...
2) 60° counterclockwise = 60°
3) 135° clockwise (360 - 135) = 225°
4) one full ring counterclockwise plus (450 - 360) = 90°
5) three full rings clockwise plus (360(4) - 1125) = 315°
Answer:
she can make 8 batches
Step-by-step explanation:
In this question , we are concerned with calculating the number of batches of cupcakes keith can make.
To make a batch, 5/8 of a cup is required.
Now she has 5 cups. The number of batches she can make will be 5/(5/8) = 5 * 8/5 = 8
Answer:
The builder worked roughly 12 hours and the plumber worked around 13. The builder got paid 330.75 so just divide 28 by that to get 11.9... then add 330.75 and 106.75 (which will be 437.50) and divide the sum by 35 the get 12.5.

Step-by-step explanation:
30 - 60 - 90 triangles have angles in the triangle measuring 30, 60, and 90 degrees. A 30 - 60 - 90 triangle also has special side ratios according to a side's location in the triangle.
The side across from the 30 degree angle is represented by x.
The side across from the 60 degree angle is represented by x
.
The side across from the 90 degree angle is represented by 2x.
45 - 45 - 90 triangles have angles in the triangle measuring 45, 45, and 90 degrees. A 45 - 45 - 90 triangle has special side ratios similar to the 30 - 60 - 90 triangle.
The side across from either of the 45 degree angles is represented by x.
The side across from the 90 degree angle is represented by x
.
These ratios can be used to find missing sides. If you know that a triangle is one of these special triangles and you also know one of its side lengths, you can plug the known length in for x in the proper place.
EX: you have a 30 - 60 - 90 triangle with a side length of 2 across from the 30 degree angle. You then know that the side across from 60 is 2
and the side across from 90 is 4.
