Cindy made a triangular shaped sculpture with an area of 63 square inches. The height of the sculpture is 9 inches. What is the base length of the sculpture?

Answers

Answer 1

Answer: area=base times height times 1/2
63=area
9=height
63=bsae times 9 times 1/2
multiply both sides by 2 to get rid of 1/2
126=base times 9
divide both sides by 9
14=base

base legnth=14 inches

Answer 2

Answer: the base is 14 because 14× 9 = 126 and 126÷2 =63

19. If the scale is 1:100 on a plan, and a fence is 7,500 mm,how many millimetres will it measure on the plan?
mm

Answers

Answer:

It will measure 75 millimetres on the plan.

Step-by-step explanation:

Given:

Scale on the plan = 1:100

Length of the fence = 7,500 mm

To find:

how many millimetres will it measure on the plan

Solution:

As the ratio on the plan is 1: 100, the for 7500 the ratio will

x : 7500

Now by cross multiplication we get

$7500 * 1 = x * 100$

$7500 = 100x$

$x =( 7500)/(100)$

x = 75

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $155 for 100 minutes of usage and $245 for 200 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x?Draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 0.9
Draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 1.1
Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 1.1
Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

Answers

The solution is "Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9"

the points are (minute,cost) pairs like the assignment states
the slope is the difference of both costs (90) divided by the minute difference (100)
so k=90/100=0.9

so the last option
