What is equivalent to 5^3 ( Choose all that apply)

Mathematics
1 answer:
Tema [17]3 years ago
8 0

Answer:

A, and D

Step-by-step explanation:

A works because when you multiply like bases, you add exponents, so we have...

  5^7*5^-4 = 5^(7+(-4)) = 5^(7 -4) = 5^3

B  doesn't work because when you divide like bases, you subtract the exponent of the denominator from the exponent of the denominator...

  5^12/5^4 = 5^(12 - 4) = 5^8

C doesn't work because there is addition.  

 5 + 5² = 5 + 25 = 30, and 5³ = 125

D works because 5^0 = 1, so we have

  5^0(5^3) = 1(5^3) = 5^3

E doesn't work because there is subtraction...

  5^3 - 5^0 = 5^3 - 1 = 124

Angles of triangle sand explain how u got each question and answer pls ! ((:
horsena [70]

Answer:

m∠1 = 41°

m∠2 = 85°

m∠3 = 95°

m∠4 = 85°

m∠5 = 36°

m∠6 = 49°

m∠7 = 96°

Step-by-step explanation:

Alright, so to start we have 2 quadrilaterals intersecting to form a triangle, which means that in the shapes with 4 angles, all angles will add up to 360°, while the triangle's angles will add up to 180°

Right off the bat, we can tell that ∠3 and ∠95° are going to be the same, because they're at a perpendicular intersection, which also means that ∠2 and ∠4 will be the same as well

Knowing the ∠3 = 95° means that ∠5 and ∠6 must add up to equal 85°, so that the whole of the triangle equals 180°

Considering that in the first quadrilateral we already have ∠90° and ∠144°, this means that ∠1 and ∠2 have to add up to 126°, to make an even 360° total

If ∠95° is supplementary to ∠2, this means ∠2 = 85°, and since ∠4 and ∠2 are the same, ∠4 also equals 85° - This leaves 41° left for ∠1, and now we can move on to the other quadrilateral

So since we know ∠4 = 85°, and we already have ∠38°, this means that ∠7 and the unmarked angle will add up to equal 237°, so that the entire shape has 360°

Since we know that ∠5 and ∠144° are supplementary, this means ∠5 is equal to 36°, which would make ∠6 = 39°

And lastly we have ∠7, which since ∠6 = 39° this means our unmarked supplementary angle must equal 141° - Now that means that ∠4 + ∠38° + ∠141° = 264° out of 360°, which leaves ∠7 to equal 96°

James has organised a game to raise money for charity at a local fair. He rolls a fair six sided dice and flips a fair coin. If
Scorpion4ik [409]

The total amount that was raised for charity is £75.

<h3>What is the total amount raised?</h3>

Here is the sample space

                  1               2            3            4            5           6

Heads        1               4            9           16            25        36

Tails           1               8            27          64           125        216

Probability of getting a number greater than 30 = 4/12 = 1/3

1/3 x 450 = 150

Total value of people getting more than 30 : 150 x £1 = £150

Total amount paid = 50 x 450 = £225

Amount raised = £225 - 150 = £75
