B - 9 + 6b = 30
You need to add all the b's up on the left side of the equation first. So it rewrites like this:
7b - 9 = 30
next you add 9 to each side to get 7b alone on the left side.
7b = 39
now divide both sides by 7 so that b is all by itself.
b = 5 4/7 or 5.57

The function f(x) is shown in this graph please help because I can’t understand this concept

Pavlova-9 [17]

Answer:

d) the slope of f(x) is greater than the slope of g(x)

Step-by-step explanation:

to find the slope of an equation, you look at its rise/run. for f(x), you can see that from one point (0, 3) to another (1, 1) it goes down 2 values (3 - 1) and over 1 value (0 + 1). because it goes down 2 values, the rise is -2, and because it moves to the side 1 value positively, the run is +1.

-2/+1 = -2. this means the slope of f(x) = -2.

finally, it says the slope of g(x) = -6, and -2 > -6. i hope this helps! :)

A company makes a cone-shaped container with a height of 15 in. The area of its base is about 78.8in.2 Approximately what is the

MakcuM [25]

Answer:

Approximately the volume of cone-shaped container is <u>393 in³</u>.

Step-by-step explanation:

Given:

A company makes a cone-shaped container with a height of 15 in.

The area of its base is about 78.8 in².

Now, to get the cone-shaped container volume.

So, we find the radius first by using formula:

Let the radius be $r.$

<u><em>(Using the value π = 3.14)</em></u>

$A_{B}=78.8\ in^2.$

$A_{B}=\pi r^2$

$78.8=3.14\times r^2$

<em>Dividing both sides by 3.14 we get:</em>

<em /> $25.09=r^2$ <em />

<em>Using square root on both sides we get:</em>

$5.00=r$

$r=5\ in.$

Thus, the radius ( $r$ ) = 5 in.

<u>The height (</u> $h$ <u>) = 15 in.</u>

Now, to get the volume of the cone-shaped container we put formula:

$Volume=\pi r^2\frac{h}{3}$

$Volume=3.14\times 5^2\times \frac{15}{3} \\\\Volume=3.14\times 25\times 5\\\\Volume=392.50\ in^3.$

Therefore, approximately the volume of the cone-shaped container is 393 in³.

3/4 of a piece of metal has a mass of 15kg.what is the mass of 2/5 of the piece of metal

olga2289 [7]

3/4=15
let,
total mass is x
x=4×15/3
=20 kg
so, total mass = 20 kg

=2×20/5
=2×4
=8 kg

Hope this helps!
