The answer would be a number squared. 3 squared is 9, 4 squared is 16 and so on. All you have to do is keep on squaring the x value, and you will get you answer.

How much is 4x+5=41

GREYUIT [131]

Answer:

x = 9

Step-by-step explanation:

4x+5=41

To solve for x, we subtract 5 from each side

4x+5-5=41-5

4x = 36

Divide each side by 4

4x/4 = 36/3

x = 9

The volume of a spherical sculpture is 256 ft³. Rhianna wants to estimate the surface area of the sculpture. To do the estimate,

Brrunno [24]

Answer:

192 $ft^2$

Step-by-step explanation:

Given that

Volume of spherical sculpture = 256 ft³

$\pi$ is used as 3.

To find:

Surface area of sculpture = ?

Solution:

First of all, let us learn about the formula for Volume and Surface Area of Sphere:

1. $Volume =\frac{4}{3}\pi r^3$

2. $Surface\ Area = 4\pi r^2$

Given volume is 256 ft³.

$256 = \dfrac{4}{3}\pi r^3\\\Rightarrow 256 = \dfrac{4}{3}\times 3 r^3\\\Rightarrow 256 = 4 r^3\\\Rightarrow r^3=64\\\Rightarrow \bold{r = 4\ ft}$

Now, let us put r = 4 in the formula of Surface Area to find the value of Surface Area:

$Surface\ Area = 4\pi 4^2 = 4 \times 3 \times 16 = \bold{192\ ft^2}$

So, approximate surface area of sculpture is 192 $ft^2$ .

Order the sides of the triangle from shortest to longest.

Genrish500 [490]

Answers:

Shortest Length = LN
Middle Length = LM
Longest Length = MN

========================================

Explanation:

Let's find the missing angle.

For any triangle, the three interior angles always add to 180

L+M+N = 180

75+50+N = 180

N+125 = 180

N = 180-125

N = 55

So we know the three angles of the triangle are

L = 75
M = 50
N = 55

We see that M = 50 is the smallest angle, so the smallest side is the segment opposite this angle. The smallest side is LN. The smallest side is always opposite the smallest angle.

Similarly, the largest side is always opposite the largest angle. The largest angle here is L = 75, so the largest side is MN.

The middle side must therefore be LM.

The diagram below shows a visual summary.
