Answer:

3.4%

Step-by-step explanation:

Find the percent increase by dividing the difference in the temperatures by the original temperature, then multiplying it by 100:

((362 - 350) / 350) x 100

(12 / 350) x 100

= approximately 3.4

So, the percent increase in temperature was approximately 3.4%

after a school election,Jamie had 3/8 of the votes Richard the only other candidate had 75 votes how many people voted for jaime
dalvyx [7]
Jamie and Richard are the only contestants of the election.

Jamie got 3/8 of the total votes.

Richard got = 1 - 3/8 = (8-3)/8 = 5/8 of total votes

Number of votes Richard got = 75

So 5/8 of total votes = 75

Total votes = 75 ÷ 5/8 = 75 × 8/5 = 120

Jamie got = 120 - 75 = 45 Votes

Adam is 159 centimeters tall and casts a shadow 105 centimeters in height. If Cara is 140 centimeters tall, how many centimeters
vodomira [7]

Answer:

The answer to your question is 12.55 cm

Step-by-step explanation:

Data

Adam                                  Cara

height = 159 cm                  height = 140 cm

shadow = 105 cm                shadow = x

Process

1.- To solve this problem use the Thales' theorem

         Cara's shadow / Cara's height = Adam's shadow / Adam's height

- Substitution

                                     x / 140 = 105 / 159

-Solve for x

                                     x = 105 (140) / 159

-Simplification

                                     x = 14700 / 159

                                     x = 92.45 cm

Cara's shadow is 92.45 cm long.

2.- If both shadows are in line, then Cara must walk forward

                105 - 92.45 cm

                12.55 cm
