The base of the prism in the diagram is rectangular, but the edges that are not parallel to the base are tilted. What is the vol

Aneli [31]

Answer:

Volume of the prism is 648 $cm^3$

Step-by-step explanation:

Given:

Base of the prism is rectangular in shape

Height of the prism = 6 cm

Base length of the prism= 12 cm

Base width of the prism= 9 cm

To Find:

Volume of the prism=?

Solution:

Volume of the prism ,

V= Base area of the prism x Height of the prism

Here in the figure base of the prism is in Rectangular form

So the base area of the prism = area of the rectangle

We know that the area of the rectangle is = length x height

Substituting the values

Area of the Rectangle = 12 x 9

Area of the Rectangle = 108

So the are of the base of the prism is 108 $cm^2$

Now

Volume of the prism,

V= 108 X 6

V= 648 $cm^3$

At the beginning of the school year, Jayden's mother put $80 in his cafeteria account. Each time Jayden orders lunch, it deducts

Gnoma [55]

Answer:

$y = 80 - 2.75n$

Step-by-step explanation:

Given

$Beginning = 80$

$Rate = 2.75$

Required

Model the situation using an equation

Represent the number of orders with n

Represent the balance with y

y is calculated as:

$y = Beginning - Rate * n$

We used minus because the amount is being deducted

$y = 80 - 2.75* n$

$y = 80 - 2.75n$

Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mista

SSSSS [86.1K]

Complete Question:

Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?

s(t)•h(t)= (3x-4)(2x-8)

= 6x² - 24x -8x - 32

= 6x² - 32x - 32

Answer:

Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.

Advice: Jamie should take note of the rule that applies when multiplying signs.

Step-by-step Explanation::

To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:

s(t)•h(t)= (3x-4)(2x-8)

Using distributive property, do the following:

$3x(2x - 8) -4(2x - 8)$

$3x*2x -3x*8 -4*2x -4*-8$

$6x^2 - 24x - 8x + 32$ (this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)

Add like terms

$6x^2 - 32x + 32$

Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.

Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.
