Kaitlin bought 4 pounds of coffee.
70-39.24=30.76
30.76 ÷ 7.69= 4
Answer:
( 1/3, 5 2/3) Or (0.33, 5.66)
Step-by-step explanation:
If you graph the 2 equations and see where they intersect, they will land on the answer.
If the shape on the red image is scaled to the shape on the blue image, the scale factor is 0.2777.
Explanation:
- The original shape's base in the red image is measured. The base of the red image is measured to be 9 units. Now we measure the same side of the blue image. The base of the blue image is measured to be 2.5 units. So after scaling, the length of the painting will be 2.5 units.
- To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the base of both images. So The scale factor =
=
= 0.2777. - So the red image is dilated by a scale factor of 0.2777 to produce the blue image.
Answer:
D.) 7:3
Step-by-step explanation:
First, find the LCM of the numbers, which is 8.
Then divide each number by 8
56÷8=7 24÷8= 3
Then, put them in a ratio
7:3
Angle A would be 10 degrees.
Complementary angles add to 90 degrees.
So 90-80=10
