Answer:

The surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.

Step-by-step explanation:

Slant height of square pyramid = l = 13 mm

Base length of square pyramid = b = 11 mm

Formula of surface area of square pyramid = $b^2+2bl$

Substitute the values in the formula :

Surface area of square pyramid = $11^2+2(11)(13)$

Surface area of square pyramid =407 sq.mm.

Hence the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.

I NEED A LOT OF HELP PLEASE! I WILL FAIL IF IT DOESNT GET DONE!

In order to solve for this, we need to find the volumes of both the cylinder and cone described.

In order to find the area of the cylinder:
We use the equation V= $\pi r^{2} h$
So, V= $\pi 6^{2}16$
The volume of the cylinder is therefore approximately <span>1809.56 $m^{3}$

For the cone:
V= $\pi r^{2} \frac{h}{3}$
So, V= $\pi 6^{2} \frac{3}{3}$
Thus, the volume of the cone is 113.1 $m^{3}$

We add these volumes together to derive the solution, which is 1922.66 $m^{3}$ </span>

In this situation, choose length and width such that 12.75=l*w. writing it as a mixed number you have 51/4=sqrt51/2*sqrt51/2 or any other combination you can use.

What is 8 square root of 3 divided by 2? no decimals, ill mark brainlist.

katovenus [111]

2.828
Step-by-step explanation:
Given : Number = 8
To Find : find the square root of 8 upto 2 decimal places
Solution :
We are supposed to find the square root of 8
Group the digits into pairs
For digits to the left of the decimal point, pair them from right to left.
For digits after decimal point, pair them from left to right).
So, we have , 08
Refer the attached figure for further steps
√8 = 2.828
Hence the square root is 2.828
Since , you asked for 2 decimal places so the answer is:
Answer:
2.82
Step-by-step explanation:
√8=2*√2= 2*1.41= 2.82

A company sells boxes of small blue pom-poms (b) for $42 and boxes of large orange pom-poms (p) for $52. They make batches of sm

Strike441 [17]

Answer:

b = 40 - p

42b + 52p = 350

Step-by-step explanation:

Given : No. of small blue pom-pom boxes = b

No. of large orange pom-poms = p

cost of 1 box of blue pom pom = $42

cost of one large orange pom-pom box = $52

Solution:

Since we are given that the company has only 40 boxes

⇒b+p=40

⇒b=40-p

Since cost of 1 box of blue pom pom = $42

So, cost of b box of blue pom pom = $42b

Since,cost of one large orange pom-pom box = $52

So,cost of p large orange pom-pom box = $52p

We are also given that the company plan to make $350

⇒42b+52p=350

Hence Option b is correct

b = 40 - p

42b + 52p = 350

What is the slope-intercept form of the equation of the line with the slope of -5/8 that passes through the point (-14,6)

inessss [21]

Step-by-step explanation:

y-y1 = m(x-x1) is the equation for a linear line in y=mx+b (slope intercept)

slope = m = -5/8

x1 = -14

y1 = 6

y-6 = -5/8 (x--14)

y-6 = -5/8 (x+14)

y-6 = -5/8x-70/8

y-48/8= -5/8x-70/8

y = -5/8x - 22/8

When x = 0, y = -22/8, which makes (0, -22/8) your y intercept
