By using the fact that the two triangles are equivalent, we will find that the value of n must be 18.4

<h3></h3><h3>How to find the length of n?</h3>

Here we can see that the horizontal line divides the triangle in such a way that the left and right sides are divided in two halfs. (we can see this because both parts have the same symbol on them)

Also both of these triangles are equivalent, so:

if x is the measure of each part in the right side we can write the equivalent relation

11.3/x = (n + 4.2)/(2x)

Now wen solve this for n:

(11.3/x)*2x = (n + 4.2)

22.6 = n + 4.2

22.6 - 4.2 = n

18.4 = n

The prices for different types and amounts of building bricks are given. Select the options that have the same cost per brick.
pickupchik [31]

Answer:

35 bricks for $25.90

35 bricks for $25.90

230 bricks for $170.2

Step-by-step explanation:

Cost per brick = number of bricks / price of bricks

1500/$1110 = $1.35

1300 / $845 = $1.54

230 / $170.20 = $1.35

100 / $75 = $1.33

35 / $25.90 = $1.35

Based on these calculations, the bricks that have the same cost per brick are :

35 bricks for $25.90

35 bricks for $25.90

230 bricks for $170.20

Which can be the first step in finding the equation of the line that passes through the points (5, -4) and (-1, 8) in slope-inte
abruzzese [7]

Answer:

y = -2x + 6

Step-by-step explanation:

Slope = (-4 - 8)/(5 + 1)

= -12/6

= -2

Equation

y - 8 = -2(x + 1)

y - 8 = -2x - 2

y = -2x + 6  <-----------slope-intercept form

I NEED HELP VOLUME OF SPHERES 5 QUESTIONS ASAP!!!!
Alexeev081 [22]

Answer:

1.)4188.79

2.) 7238.23

3.)1.02

4.)4189

5.)170 cm³

Step-by-step explanation:

1.) 4πr2 * 5

2.) 4πr2 * 12

3.) V = 4/3(PI*r3). *4.5

4.) V = 4/3 π r ^3 * 10

5.) Given:

Cylindrical container: height = 18 cm ; diameter = 6 cm.

3 balls each have a radius of 3 cm.

Volume of a cylinder = π r² h

V = 3.14 * (3cm)² * 18 cm

V = 508.68 cm³

Volume of rubber ball = 4/3  π r³

V = 4/3 * 3.14 * (3cm)³

V = 113.04 cm³

113.04 cm³  * 3 balls = 339.12 cm³

508.68 cm³ - 339.12 cm³ = 169.56 cm³ or 170 cm³

There is 170 cm³ free space in the container.
