HELP ASAP!! AND PLEASE EXPLAIN! The pyramid has a square base of 230 meters on each side and a height of 147 meters. Find the volume of the pyramid if the slant height is 186.63 meters.

Step-by-step explanation:

the slope of a line or linear equation is always the factor of the driving variable.

usually in the form of

y = ax + b

x is the variable, and a the slope.

but in our case the variable is called "n".

it does not matter, the same principle applies.

the slope is the factor of n : 1050.

and as the slope is always the ratio y/x, we are looking for a fraction form, and that would be 1050/1.

so, the third answer is correct.

Answer:

Step-by-step explanation:

5x is greater than -20 because if you look at the worst possible solution which is 5(0) it's still larger than -20 because of the number line 0 is greater than -20 so yes 5x is greater than -20

Answer:

x = 20

y = √3 / 10

Step-by-step explanation:

The cosine ratio gives the ratio between the adjacent side and the hypotenuse.

The sine ratio gives the ratio between the opposite side and the hypotenuse.

Taking cosine ratio to find x :

cos 60° = 10/x

1/2 = 10/x

x = 20

Taking sine ratio to find y :

sin 60° = y/x

√3 / 2 = y/20

y = √3 / 10

Answer:

x= 20 ,  y= 10√3

Step-by-step explanation:

This question is clearly a trigonometry question

Please bare in mind :

Cos 60 = 1/2

Sin 60 = √3/2

Tan 60 = √3

Side x is the hypotenuse (h)

Side y is the Opposite (o)

And side with length of 10 is adjacent (a)

To find x, we have a, and we need h

So we use C = a/h

Cos 60 = 10/h

h = 10/Cos 60

h = 10/0.5

h = 20 ,  x=20

To find y, we can use pythagaros as we found the value of x :

10² + y² = x²

10² + y² = 20²

y² = 20²-10²

y² = 300

y = √300

y= √100×3   y=√100 × √3

y = 10√3

This is our y value

Another way to find y is trigonometry :

We have a and we need o so we use :

T = o/a

Tan 60  = o/10

o = 10×tan 60

o = 10×√3

o = 10√3 ,  y=10√3

a) Angles ACB in ∆ABC and ECD in ∆EDC are congruent, since they form a vertical angle pair.

Angles ABC and EDC are clearly congruent, since they are both right angles.

The legs AB and ED are parallel, so angles BAC and DEC are congruent alternating interior angles.

Then ∆ABC is similar to ∆CDE by the angle-angle-angle postulate.

b) Because they're similar, corresponding sides occur in a fixed ratio, which tells us that

CD/BC = ED/AB

r = 9 feet

We know that,

Volume of cylinder is,

V = πr²h

Substitute all the values, we get;

V = 3.14 × 9² × 8

Answer:

175 degrees.

Step-by-step explanation:

Supplementary angles add up to 180 degrees

Therefore the answer is:

180 - 5

= 175 degrees.

Hi Student!

The first step to almost any problem is that we must concentrate the important information that is given to us in the problem.  This problem gives us information including that the measure of an angle is 5 degrees and that this angle is part of a supplementary pair.  Let's define what a supplementary pair or angles are.

Now that we have our definitions and important information, we can move onto the next part which is actually finding the other angle.  This step is simple now that we know that supplementary angles add up to 180.  We can just create an equation that will help us determine our solution.

[tex]angle_1\ +\ angle_2 = 180\ degrees[/tex]

[tex]5\ degrees\ +\ angle_2 = 180\ degrees[/tex]

[tex]5\ degrees-5\ degrees\ +\ angle_2 = 180\ degrees-5\ degrees[/tex]

[tex]angle_2 = 175\ degrees[/tex]

Therefore, our final solution to the supplementary angle of 5 degrees is 175 degrees which can be found by subtracting the given angle from 180.

Answer:

173

Step-by-step explanation:

Assume the natural number is x.

x/12 = ... R 5

x/15 = ... R 8

x/18 = ... R 11

Thus, x+7 is divisible by 12, 15 and 18 all together.

The smallest possible number of x+7 can be calculated with prime factorization.

12=2^2 * 3

15=3 * 5

18=2 * 3^2

The smallest possible number for x+7 is 2^2 * 3^2 * 5 = 4 * 9 * 5 = 180.

Therefore, the smallest possible solution for x is 180 - 7 = 173.

Answer:

a ............,....

Step-by-step explanation:

....

....,,

Step-by-step explanation:

a.

the arc angle AC = 180° (since this is a diameter).

the arc angle BC = 60°.

so,

arc angle AB = arc angle AC - arc angle BC = 120°.

b.

the exterior angle of a circle segment at the circle arc is half of the interior angle at the center of the same segment.

the angle A = arc angle BC / 2 = 30°.

c.

the same principle as in b.

the angle C = arc angle AB /2 = 60°.

d.

the arc angle AD = the angle at AOD (that is how arc angles are defined).

the angle AOD = the angle AOF.

the sum of all angles in a triangle is always 180°.

angle AOD = AOF = 180 - 90 - angle A = 60°.

e.

as explained, this is the same as the arc angle AD and therefore the same as d.

it is 60°.

f.

the arc angle CE = the arc angle AD = 60°.

remember, the angles of intersecting lines are the same (just side mirrored) on both sides of each line.

g.

the arc angle ABE = arc angle AB + arc angle BC +

+ arc angle CE = 120 + 60 + 60 =

= 240°

h.

the angle AOE = the arc angle AE = the remainder of 360 minus the arc angle ABE of g.

so, angle AOE = 360 - 240 = 120°

By solving a little system of equations we will see that the two numbers are 12 and 31.

Let's define the two numbers as a and b.

We know that one of the numbers is 7 more than twice the other, so we have:

a = 2b + 7

We also know that the sum of the two numbers is 43, so we get:

a + b = 43

Replacing the first equation into the second one we get:

2b + 7 + b = 43

3b = 43 - 7 = 36

b = 36/3 = 12

Now that we know b, we can find a:

a = 2*12 + 7 = 31

So the numbers are 12 and 31.

The total amount of change, in cents, that was found is determined as 96 cents.

The total amount of change is calculated as follows;

let the total = T

there was at least one coin of each type

T = p + n + d + q

more than half of the coins were pennies

[tex]\frac{p+n + d + q }{2} \leq p[/tex]

more than half = pennies

next, we have; nickels + dimes + quarters

y(dimes) = $0.25

y(0.1) = 0.25

y = 0.25/0.1

y = 2.5 ≅ 3

dimes = 3 coins

since dimes = 3 coins, number of nickels is now calculated as;

x(0.05) = 3(0.1)

x = (0.3)/(0.05)

x = 6 coins

nickels = 6 coins

Total coins = nickels + dimes + quarters + pennies

Total coins = nickels + dimes + quarters + pennies

let pennies = 7

Total coins = 6 + 3 + 1 + 7

Total coins = 17

half of 17 = 8.5

7 is less than half (8.5), number of pennies cannot be 7, since more than half of the coins are pennies.

let pennies = 11

Total coins = 6 + 3 + 1 + 11

Total coins = 21

half = 10.5

more than half = number of pennies = 11

11($0.01) + 6($0.05) + 3($0.1) + 1($0.25) = $0.96 = 96 cents

Step-by-step explanation:

hope it helps and give brainliest

Step-by-step explanation:

when throwing 2 coins, there are 4 equally probable outcomes :

1 head 1 tail

1 tail 1 head

2 heads

2 tails

so, each outcome has a probability of 1/4.

the probability to not get 2 tails is the sum of the probabilities of 3 of these outcomes. so, it is

3/4.

to get 2 tails first at the xth attempt means that it did not happen at all x-1 attempts before.

that probability for that is

(3/4)^(x-1)

and then it happens. the probability for that is 1/4.

so, the total probability for that event is

(3/4)^(x-1) × 1/4 = (3^(x-1)) / (4^x)

so, for x = 7 that gives us a probability of
