Answer: 65°

<u>Step-by-step explanation:</u>

$E=w(t_f-t_o)\\\\E: 10\ cubic\ feet\times \dfrac{1000\ BTU}{1\ cubic\ foot}\times \ 60\%\quad \rightarrow \quad E=6000\ BTU\\\\\\w:50\ gallons\times \dfrac{8\ pounds}{1\ gallon}\quad \rightarrow \quad w=400\ pounds\\\\\\\\E=w(t_f-t_o)\\\\6000=400(t_f-50)\\\\\dfrac{6000}{400}=\dfrac{400(t_f-50)}{400}\\\\.\quad 15=t_f-50\\\\\\.\quad 15=t_f-50\\.\ \underline{+50}\quad \underline{\quad \ +50}\\.\quad 65=t_f$

2. Mrs. Siebenaller bought a “bus” for $25,000 with a 7% interest rate. Mrs. S. gets a loan to pay off in 5 years. How much inte

PSYCHO15rus [73]

Answer: the correct option is A

Step-by-step explanation:

Cost of the bus is $25000. She took a loan of $25000 to be paid of in 5 years at an interest rate of 7%.

The formula for simple interest is expressed as

I = PRT/100

Where

I = interest

P = principal or initial amount borrowed

T = time in years

R = interest rate in percentage

From the information given,

P = 25000

R = 7%

T = 5 years

Therefore

I = (25000 × 7 × 5)/100 = 875000/100

I = $8750

Which line shows theINITIAL error in volume work?

aliina [53]

In step 2, V = $\frac{4}{3}(3.14)(37.5)$ show the error in volume work.

Solution:

Given data:

The steps shows it is sphere.

Radius of the sphere = 12.5

The value of π = 3.14

Volume of the sphere = $\frac{4}{3} \pi r^3$

Step 1:

$$V=\frac{4}{3} (3.14)(12.5)^3$

$$V=\frac{4}{3} (3.14)(12.5)(12.5)(12.5)$

Step 2:

$$V=\frac{4}{3} (3.14)(1953.125)$

Step 3:

$$V=\frac{4}{3} (6132.81)$

Step 4:

V = 8177.08 cubic units

This is the correct solution.

But in the given options, in step 2, 12.5 is multiplied by 3.

That is not the correct step. You have to do 12.5 × 12.5 × 12.5.

Hence in step 2, V = $\frac{4}{3}(3.14)(37.5)$ show the error in volume work.
