Slope = Change in y direction / Change in x direction

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{-5-(-10)}{-2-(-9)} = \frac{5}{7}$

I believe you would subtract 64 from 180 (since it’s the measurement of the straight line) that would leave you with 116. From there you would divide that by 2 since it’s split in 1/2 which would leave you with 58. Therefore, the answer is x=58

Find the surface area of the square pyramid shown below. (Measurements in picture)

Sloan [31]

Given:

Side length of base = 8

Slant height = 6

To find:

The surface area of the square pyramid.

Solution:

Surface area:

$$SA=A+\frac{1}{2} p s$

where A is the area of base

p is the perimeter of base

s is the slant height

Area of base (A) = 8 × 8

= 64

Perimeter of base(P) = 4 × 8

= 32

Substitute these in the formula:

$$SA=64+\frac{1}{2} \times 32 \times 6$

$$SA=64+96$

$$SA=160$

The surface area of the square pyramid is 160 unit².

Find the volume of this sphere. Use 3 for TT. V V ~ [?]cm3 V = nr3 r=6cm

Katen [24]

Answer:

$V = 864cm^3$

Step-by-step explanation:

Given

$r = 6$

$\pi = 3$

Required

The volume of the sphere

This is calculated as:

$V = \frac{4}{3} \pi r^3$

So, we have:

$V = \frac{4}{3} *3 *6^3$

$V = \frac{4}{3} *3 *216$

This gives:

$V = 4 *216$

$V = 864$

Please help me I will offer 20 points

sveticcg [70]

Answer:

9.3 x 8.5 = 79.05

7.6 x 2.4 = 18.24

an easier way to multiply decimals is to take away decimals and add later

example: 9.3x8.5 > 93x85 = 7905 since there are two places behind the decimal add that many to the solution 7905 > 79.05
