In order to complete the circuit, the curved plate on the topmost right side of the circuit must be moved downwards to the end. The length of the total plates to be added is 100cm. Refer to the use of polygons.

<h3>How did we arrive at 100cm above?</h3>

Step 1

In order to complete the circuit, the curved plate on the topmost right side of the circuit must be moved downwards to the end. This is already existing on the circuit so it is not part of the plate to be added.

Step 2

Using the plate with the straight line, the other spaces which are 5 in number will be completed. The total length of plates used will amount to 100cm.

Because the plate is equal in length and height, the total number of plates used is:

20 * 4 = 100cm.

Alice is thinking of a number n that she wants her sister to guess. Her first clue is that two less than six times her number is

Alik [6]

Answer:

10 < 6n -2 ≤ 34

n= {3, 4, 5, 6}

Step-by-step explanation:

number

⇒ n

two less than six times the number

⇒ 6n -2

it is between ten and thirty-four (inclusive)

⇒ 10 < 6n -2 ≤ 34

we can solve it as:

10 < 6n -2 ≤ 34 ⇒ add 2 to all sides
12 < 6n ≤ 36 ⇒ divide by 6 all sides
2 < n ≤ 6
n= (2, 6]

n= {3, 4, 5, 6}

Please help me I tried all day

1) Rent:
2200*0.3 = 660

2)Utilities:
2200/4 = 550

3)Transportation:
2200*0.1 = 220

4)Groceries:
2200*0.2 = 440

5)Entertainment:
2200*0.1 = 220

6)Other:
2200/20 = 110

Thus the thing that costs 550 is the utilities.
Hope this helps! :)

The shape of the distribution of the time required to get an oil change at a 15-minute oil-change facility is unknown. However,

Mars2501 [29]

Answer:

(a) Probability that a random sample of n = 45 oil changes results in a sample mean time < 10 minutes i=0.0001.

(b) The mean oil-change time is 15.55 minutes.

Step-by-step explanation:

Let us denote the sample mean time as x

From the Then x = mean time = 16.2 minutes

The given standard deviation = 3.4 minutes

The value of n sample size = 45

Alex Ar [27]

Answer:

answer c-[150-25(pi)]h cm

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

(Please have a look at the attached photo)

My answer:

Given the information:

box length-15
box width-10
box and jar height unknown (h)
radius of jar-5

As we all know that, the formula used to determine the volume of the box is:

V = the length* the width * the height

In this situation, we have:

V = 15*10*h

= 150h cubic units

The volume of the jar

V = the base*the height

In this situation, we have:

V = h*π $r^{2}$

<=> V = $5^{2} h$ π = 25πh

=> The volume of the box that is not occupied by the jar

= The volume of the box - The volume of the jar

= 150h - 25πh

= h(150 - 25π)

We choose C
