Answer:

Option C. 12√3

Step-by-step explanation:

Lateral area of the solid figure will be = 3×(one lateral side )

Area of a lateral side of the given triangle = (1/2) × (height) × (Base)

Height of an isosceles triangle with a side 4 will be = √(4² - 2²) = √(16-4)= √12 = 2√3

Now area of one lateral side = (1/2)×(2√3)×(4) = 4√3

Therefore lateral area of the solid figure = 3×(4√3) = 12√3

Answer:

from (-4,1) the line will go up to (-2,2) then (0,3)

Step-by-step explanation:

the slope 1/2 dictates that the line will go up by 1 unit for every 2 units, then we just plot said line from the point given (-4,1) where we go up y by 1 and we go left on x by 2

image could not be provided at this time, tho the line will have a slope that is between horizontal and increasing (to the left) at roughly 30 degrees ish

Step-by-step explanation:

We will first find the prime factorization of 32 and 39. After we will calculate the factors of 32 and 39 and find the biggest common factor number .

32=2^5

39=3^1*13^1

-

List of positive integer factors of 32 that divides 32 without a remainder.

1,2,4,8,16

List of positive integer factors of 39 that divides 32 without a remainder.

1,3,13

We found the factors and prime factorization of 32 and 39. The biggest common factor number is the GCF number.

So the greatest common factor 32 and 39 is 1.

Answer:

The formula for volume of a cone is area of a circle times height, divided by 3.

Therefore volume is pi times radius squared times height, divided by 3.

V = (3.14)(14)^2 (14)/3

V = (3.14) (196)(14)/3

V = (3.14) (2744)/3

V = 8616.16/3

V = 2872.05333

to the nearest hundredth is 2872.05 cubic yards.

∠ACB

Step-by-step explanation:

we have three options for angles in triangle ABC:

- ∠CAB

- ∠ABC

- ∠ACB

∠ACB is the only angle out of the three given that doesn't directly touch side AB, so this must be our answer

Answer:

(PQ) = (TU)              (UV) = (QR)            m∠T= m∠P 

m∠R= m∠V            (TV) = (PR)

m∠Q= m∠U           m∠U= m∠Q

The coin is an illustration of probability, and the probability of getting two heads and a tail is 3/8

The sample space of tossing a coin three times is:

S = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

On the sample space, we have:

Two heads and a tail = 3

Sample size = 8

The required probability is then calculated using:

P = 3/8

Hence, the probability of getting two heads and a tail is 3/8
