Priya is simplifying the expression $$ Her work is shown to the left. Priya's work is incorrect. Explain the error she made

Answers

Answer 1

Step-by-step explanation:

P.S - The exact question is -

Given - Priya is simplifying the expression -2(4 - 2x) - 3 - 2x  Her work is shown to the left.  

To find - Priya's work is incorrect.  Explain the error she made.

Proof -

Priya simplified the problem as follows :

-2( 4 - 2x ) - 3 - 2x

-8 - 2x - 3 - 2x

-11 - 4x

But the simplification has to be like

-2( 4 - 2x ) - 3 - 2x

⇒-2(4) - 2(-2x) - 3 - 2x

⇒-8 + 4x - 3 - 2x

⇒-8 - 3 + 4x - 2x

⇒-11 + 2x

So, Priya made an error in the second line.

In the second line it has to be -8 + 4x - 3 - 2x but Priya has written -8 - 2x - 3 - 2x.

The base of a cone has a radius of 6 centimeters. The cone is 7 centimeters tall. What is the volume of the cone to the nearest tenth

Answers

Answer:264cm^3

Step-by-step explanation:

Volume of a cone= 1/3×A×h, where A is base area

Base area=πr^2

=22/7× 6^2

Solve for x . x/2 + 1.1= -2.1

Answers

Answer: x = 1.6

Step-by-step explanation:

Start by Identifying what you need to keep, in this case that would be X. In order to solve for x, you would need to get rid of any co-efficients. (example: +1.1) To get rid of them, you have to do the opposite action of what it's doing to the equation. (subtraction)

1.1- (-2.1) = 3.2 (if you subtract a negative, it turns positive/ you add) leaving you with x/2 = 3.2.

Now that we have our coefficient out the way, we have to get rid of the division so we can only solve for x. We do that by dividing the remainder of the equation by 2

3.2/2 = 1.6

Leaving us with the answer, x = 1.6

The mean price of eggs over this 11-year period is The median price of eggs over this 11 -year period is

Answers

Answer:

Mean price of eggs = $1.64

Median price of eggs = $1.69

Step-by-step explanation:

Mean is the average of the given data

Mean = sum of data/sample size

Sum of data = 1.19+1.21+1.50+1.93+1.50+1.52+1.69+1.69+1.87+2.00+1.96

Sum of data = $18.06

Sample size = 11

Mean price of eggs =18.06/11

Mean price of eggs = $1.64

Hence the mean price of eggs over this 11-year period is $1.64

Median is the price in the middle after rearrangement

Rearranging the data

1.19, 1.21, 1.50, 1.50, 1.52,) 1.69, (1.69, 1.87, 1.93, 1.96, 2.00

Since 1.69 falls in the middle after rearranging;

Hence the median price of eggs over this 11 -year period is $1.69

Step-by-step explanation:

Think of the shape being made up of a square on top that is 4 units by 4 units and a trapezoid on the bottom with bases 4 and 2 and height 4.

area = area of rectangle + area of trapezoid

area = LW + (b1 + b2)h/2

area = 4 * 4 + (4 + 2)(4)/2

area = 16 + 12

area = 28

a. What transformation maps square 1 onto square 2?
b. What transformation maps square 2 onto square 3?
c. What transformation maps square 1 onto square 5?

Answers

Answer:

A) Translation

B) Reflection

C) Rotation

Step-by-step explanation:

The transformation types in mathematics are;

Reflection, translation, rotation and dilation.

We can see that the squares are all the same size, it's just the position of the stars that will aid us in knowing the specific transformation.

A) We can see that square 2 is the exact same thing as square 1. Just that it was shifted to the right of square 1. Thus, it was translated and the transformation is translation.

B) We can see that the star in square 3 is the exact mirror copy and location from square 2. Thus, this is a reflection.

C) We can see that the position of the star in square 5 is top while that in square 1 is at the left corner. This can only be achieved by rotation.

The ratio of the length to the width to the height of an open rectangular tank is 10: 5: 8. The height is 18 feet longer than the width. What is the volume of the tank

Answers

Answer:

hi

Step-by-step explanation:

how are you

Answer:  A: L: W: H = 10: 5: 8

Step-by-step explanation:  The height of the tank is 18 feet longer than the width

H = 8 parts, W = 5 parts => 8 – 5 parts = 18 feet i.e. 3 parts = 18, 1 part = 6 feet

Hence, L = 10 * 6 = 60 feet

W = 5 * 6 = 30 feet

H = 8 * 6 = 48 feet

Volume = 60 * 30 * 48 = 86400 ft³

Surface Area = 2 * (30 * 60 + 48 * 60 + 30 * 48) =12240 ft²
