The surface area of a solid is just the total area of all its faces. We know a cube has 6 identical faces with area s^2 where s is the side length.

So 6s^2 is the surface area. We can use this to find s.

6s^2 = 600

s^2 = 100

s = 10 cm

If sine theta equals three over four, what are the values of cos θ and tan θ?
ratelena [41]

Answer:

In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus  three over root seven

Step-by-step explanation:

Given that sin ∅ =3/4 It means the ratio of the opposite side to the hypotenuse side is 3:4.

Using the Pythagoras theorem we can calculate the hypotenuse adjacent as follows.

a²+b²=c²

a²=c²-b²

a²=4²-3²

a²=16-9

a²=7

a=√7

Then Cos ∅= opposite/ adjacent

=√7/4

Then Tan ∅ = opposite/adjacent

=3/√7

In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus  three over root seven.

What is the sample space for a 5 sided number cube?
grigory [225]

Answer:

{1, 2, 3, 4, 5}

Step-by-step explanation:

Sample space is the set of all possible outcomes. Supposing that the 5 sided number cube has numbers one to five on its sides, the possible outcomes are the numbers that can be rolled, then its sample space is: {1, 2, 3, 4, 5}

Colton earns $7 per hour plus $1.50 for each pizza delivery. The expression 7h + 1.50d can be used to find the total earings aft
Rina8888 [55]
Since the expression 7h + 1.50d can be used to find the total earnings. We just need to substitute the given data to the expression to solve the problem.

7(15) + 1.50(8)
105 + 12 = 117

Colton's total earnings after working 15 hours and making 8 deliveries is 117 dollars.
