Which estimation could be used to make sure the answer is reasonable? Claudia mixed 16.7 pounds of sand with 12.6 pounds of soil

. She used 22.1 pounds of this mixture to fill a garden pot. How much of the mixture was left over? A. Answer: The amount left over was 7.2 pounds. Estimation: 16.7 + 12.6 is about 30. 30 pounds – 22 pounds = 8 pounds The amount left over was a little less than 8 pounds. B. Answer: The amount left over was 51.4 pounds. Estimation: 16.7 + 12.6 is about 30. 30 pounds + 22 pounds = 52 pounds The amount left over was about 52 pounds. C. Answer: The amount left over was 5.9 pounds. Estimation: 16 + 12 is about 28. 28 pounds – 22 pounds = 6 pounds The amount left over was a little less than 6 pounds.

The answer for your question is a). Because if you add 12.6 pounds by 16.7 pounds you will get 29.3 as your answer.the estimated answer is 30 and,22.1 estimated is 22.Finally,you just subtract 30 by 22 and you get your answer as 8.

Use the graph shown to find the following
navik [9.2K]

Answer:

Step-by-step explanation:

Domain of the function will be,

{x ∈ R | x ≠ -2}

Range of the function is,

{y ∈ R | y ≠ -4}

Intercepts of the function,

Their are no intercepts of the given rational function.

Horizontal asymptotes:

Horizontal line parallel to x-axis representing discontinuity.

y = -4

Vertical asymptotes:

Vertical line parallel to y-axis representing discontinuity.

x = -2

No oblique asymptotes.

What is the value of 36X negative Y over to when X equals three and Y equals -6
Rus_ich [418]

<u><em>Note:</em></u>

<em>Your question is a little unclear. But, from my understanding, I assume you may be asking the evaluation of the expression 36x - y when x = 3 and y = -6.</em>

<em>so I will solve based on my assumption which anyways would clear your concept.</em>

Answer:

The value of 36x - y when x = 3 and y = -6 will be: 114

Step-by-step explanation:

Given

Assuming the expression

36x - y

To Determine

Evaluate 36x - y when x = 3 and y = -6

Given the expression

36x - y

substitute x = 3 and y = -6 to evaluate the expression

36x-y= 36(3) - (-6)

            = 108+6

            = 114

Therefore, the value of 36x - y when x = 3 and y = -6 will be: 114

Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother. What percent of the baseball cards di
jeka94

Answer:

85%

Step-by-step explanation:

Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother.

The number of baseball cards he gave to his brother is :

120 - 18 = 102 baseball cards

The percent of the baseball cards he gave to his brother is calculated as:

(Number of baseball cards given to his brother/ Total number of baseball cards) × 100

= 102/120 × 100

= 85%

The percent of baseball cards Evans gave his brother is 85%

A three inch diameter pulley on an electric motor that runs at 1800
Bezzdna [24]

Answer:

a) 3 inch pulley: 11,309.7 radians/min

6) 6 inch pulley: 5654.7 radians/min

b) 900 RPM (revolutions per minute)

Step-by-step explanation:

Hi!

When a pulley wirh radius R rotantes an angle θ, the arc length travelled by a point on its rim is Rθ.  Then the tangential speed V is related to angular speed  ω as:

V=R\omega

When you connect two pulleys with a belt, if the belt doesn't slip, each point of the belt has the same speed as each point in the rim of both pulleys: Then, both pulleys have the same tangential speed:

\omega_1 R_1 = \omega_2 R_2\\

\omega_2 = \omega_1 \frac{R_1}{R_2} =1800RPM* \frac{3}{6}= 900RPM

We need to convert RPM to radias per minute. One revolution is 2π radians, then:

\omega_1 = 1800*2\pi \frac{radians}{min} = 11,309.7\frac{radians}{min}

\omega_2 = 5654.7 \frac{radians}{min}

The saw rotates with the same angular speed as the 6 inch pulley: 900RPM
