Aphotographer charges a sitting fee of $15, and charges $4 for each 5-in. by 7 in. photograph the customer orders. the linear function can be used to calculate the customer’s cost (c) based on the number of photographs (n) purchased. how many photographs can be purchased if you cannot spend more than $50.00?

Fast! find the length of cu. the triangles are similar. show your work.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.

The table below shows the angle measurements for triangle abc and triangle xyz. if triangle abc is similar to triangle xyz, what does angle z equal, in degrees?
