A flagpole casts a shadow of 25.5 meters long. Tim stands at a distance of 15.4 meters from the base of the flagpole, such that the end of Tim's shadow meets the end of the flagpole's shadow. If Tim is 2.3 meters tall, determine and state the height of the flagpole to the nearest tenth of a meter.

Answers

Answer:

5.8 meters

Step-by-step explanation:

The formula to calculate this is given as:

Height/ Shadow

Shadow of the pole = 25.5 m

Height of the pole = x m

Tim's shadow = Height of the pole - Tim's distance

25.5 m - 15.4 m = 10.1 m

Tim's height = 2.3 m

Hence:

x/25.5 = 2.3/10.1

Cross Multiply

10.1x = 25.5 × 2.3

x = 25.5 × 2.3/10.1

x = 5.8069306931 m

Approximately = 5.8m

Hence, the height of the flagpole = 5.8m

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store. The 0.425 kg box was on sale for $3.59, the 0.74 kg box was on sale for $4.88, and the 0.95 kg box was on sale for $7.29. Which box of cookies was the best buy? Explain your reasoning. To get you started: 3.59 : 0.425 1kg/ 0.425kg= 2.35 0.425 x 2.35= 1kg $3.59 x 2.35= $8.44 3.59 : 0.425 -> $8.44 : 1kg

Answers

Answer:

The best buy is the 0.74 kg box

Step-by-step explanation:

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.

We find the unit price for 1 box

a) The 0.425 kg box was on sale for $3.59

= 1 kg = $3.25/0.425

= $7.6470588235

b) the 0.74 kg box was on sale for $4.88,

1 kg = $4.88/0.7$

= $6.5945945946

c) the 0.95 kg box was on sale for $7.29.

1 kg = $7.29/0.95

= $7.6736842105

Which box of cookies was the best buy?

The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.

if $850 grows to $1125 at an interest rate of 12.6% compounded continuously, how long has the money been in the account?

Answers

Answer:

22 years approx.

Step-by-step explanation:

Step one

Given data

Principal P= $850

final amount A= $1125

rate r= 12.6%

Calculate time, solve for t

t = ln(A/P) / r

Step two:

Substitute

t= ln (1125/850)/0.0126

t=ln 1.32/0.0126

t= 0.277/0.0126

t=21.9

t= 22 years approx.
