ABCD is a rectangle. Its diagonals are AC and BD. If AC = 12cm, then BD = _______cm

defon

Answer:

$BD = 12\ cm$

Step-by-step explanation:

Given

Shape: Rectangle

Diagonals: AC and BD

$AC = 12\ cm$

Required

Determine BD

From the question, we understand that the shape is a rectangle and its diagonals are AC and BD

Every rectangle has 2 diagonals, both of which are equal.

This implies that:

$BD = AC$

Recall that:

$AC = 12\ cm$

Hence,

$BD = 12\ cm$

A cylinder has a radius of 5x + 4 and a height of 2x + 5. Which polynomial in standard form best describes the total volume of t

Nana76 [90]

Answer:

Step-by-step explanation:

Volume = pi·(r^2)*h

r = radius = (5x+4)

h = height = (2x+5)

Volume = pi·(r^2)

Volume = pi·(5x+4)^2*(2x+8)

Volume = pi·(25x^2+40x+16)*(2x+8)

Volume = pi·(50x^2+80x+32+200x^2+32x+128)

Volume = pi·(250x^2+112x+160)

what is consecutive whole numbers? I have to write an algebraic expression for the sum of three consecutive whole numbers... :(

Agata [3.3K]

Answer:

Consecutive whole numbers (or integers) are numbers that directly follow one another.

Eg: 1, 2, 3, 4, 5 are consecutive whole numbers.

Step-by-step explanation:

Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108.

let the three consecutive whole numbers is x, x+1,and x+2

x + x+1 + x+2 = 4+2(x+1)

3x+3=4+2x+2

3x-2x=6-3

x=3

the other two numbers are 3+1=4,and 3+2=5

so the three numbers are 3,4 and 5

Price-club sells a 12-ounce package of spaghetti noodles for $3.44 and Shop Mart sells a 2-pound box of spaghetti noodles for $8

Eva8 [605]

The unit price per ounce at Price club is $0.29 and the unit price per ounce at Shop Mart is $0.26

Step-by-step explanation:

Price of 12 ounce package at Price Club = $3.44

Unit rate per ounce = $\frac{Price\ of\ package}{Weight\ of\ package}$

Unit rate per ounce = $\frac{3.44}{12} = \$0.29$

Price of 2 pound box at Shop Mart= $8.35

1 pound = 16 ounce

2 pound = 16*2 = 32 ounces

Unit rate per ounce = $\frac{Price\ of\ package}{Weight\ of\ package}$

Unit rate per ounce = $\frac{8.35}{32} = \$0.26$

The unit price per ounce at Price club is $0.29 and the unit price per ounce at Shop Mart is $0.26
