You have a function that takes in an X value and produces a Y value. The y value equals 24 times the x value, plus 4 more. What'

lapo4ka [179]

Answer:

100

Step-by-step explanation:

First, write out the equation

y = 24x + 4

Then plug in x = 4 to solve for y

y = 24x + 4

y = (24)(4) + 4

y = 100

A solid silver paperweight in the form of a square pyramid is shown below. If silver costs $0.12 per cubic centimeter, how much

Rufina [12.5K]

Answer:

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

$V=a^2\frac{h}{3}$

So its just:

$8.8^2\frac{12.5}{3} = 322.67 cm^3$

Then you just multiply the volume by the cost per cubic centimetre:

$322.67cm^3*$0.12=$38.704$

After just multiply the cost of one by how many you want, which is 6:

$38/704*6=232.32$

Please help. I am getting in trouble so please try to be correct...

vichka [17]

Answer: The answer is A 17in2

Step-by-step explanation:

In the question it states that the triangles are congruent (both the same).

first I found the area of the top orange triangle.

the formula to find the area of a triangle is $\frac{1}{2} bh$ (base times Height).

so I did $\frac{1}{2} 3.23* 5.12$ which gave me 8.27.

Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.

the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)
