The ratio will be 100/20 or 5:1. Read as for every 5 purple disks , there is 1 green disk.
Answer:
A Linear function is an equation whose graph is a straight line. It has the following form; y = a + bx.
A linear function contains one independent variable and one dependent variable. X is the independent variable and y is the dependent variable.
The answer is a) y = 3x + 5

Answer:
a) yes; 12/15/17 ~ 20/25/x; SAS
b) x = 28 1/3
Step-by-step explanation:
The left-side segments are in the ratio ...
top : bottom = 12 : 8 = 3 : 2
The right side segments are in the ratio ...
top : bottom = 15 : 10 = 3 : 2
These are the same ratio, and the angle at the peak is the same in both triangles, so the triangles are similar by the SAS postulate.
Normally, a similarity statement would identify the triangles by the labels on their vertices. Here, there are no such labels, so we choose to write the statement in terms of the side lengths, shortest to longest:
12/15/17 ~ 20/25/x
__
The sides of similar triangles are proportional, so the ratio of longest to shortest sides will be the same in the two triangles. In the smaller triangle, the longest side is 17/12 times the length of the shortest side. The value of x will be 17/12 times the length of the shortest side in the larger triangle:
x = 17/12 · 20 = 340/12
x = 28 1/3
A baker can decorate 1.4 cupcakes in 1 minute.
Step-by-step explanation:
42 cupcakes are decorated in 30 minutes by the baker. We need to find how many cupcakes can the baker decorate per minute?
Solving:
In 30 minutes cupcakes are decorated = 42
in 1 minute cupcakes are decorated = 42/30 = 1.4
So, A baker can decorate 1.4 cupcakes in 1 minute.
