Place each triangle in a fraction (side over side), and set each equal to each other.

6/9 = x/15

Isolate the x, cross multiply

6(15) = 9(x)

Simplify.

90 = 9x

Isolate the x, divide 9 from both sides

90/9 = 9x/9

x = 90/9

x = 10

Find the scale factor, find out what number is being multiplied to make the measurements become from one number to the other. Divide one of the larger triangle's sides with the smaller.

15/9 = 1.67 (rounded).

The scale factor is ~1.67

hope this helps

2x – 5 > 3 or 11 – 3x > -2
IRISSAK [1]

Answer:

x > 4 and x <3

Step-by-step explanation:

Given the system of inequalities

2x – 5 > 3 or 11 – 3x > -2

for 2x – 5 > 3

2x > 3+5

2x>8

x>8/2

x> 4

For 11-3x > -2

-3x > 2-11

-3x > -9

x < -9/-3

x<3

hence the result will be x > 4 and x <3

Finger [1]

Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase
