Which of the following numbers are irrational?
Slav-nsk [51]

The numbers that are irrational are ∛4  and 4 + √5

<h3>How to determine which of the numbers are irrational?</h3>

The numbers are given as:

negative four and 8237 ten thousandths, one half pi, cube root of four, and four plus the square root of twenty-five

Rewrite properly as:

-4.8237, π/2, ∛4 and 4 + √5

When the above numbers are evaluated, we have:

-4.8237 = -4.8237

π/2 = 11/7

∛4 = 1.5874.....

4 + √5 = 6.23606.....

Irrational numbers are numbers that cannot be represented as a fraction of two integers and they are always non-terminating decimals

∛4  and 4 + √5 are non-terminating decimals

Hence, the numbers that are irrational are ∛4  and 4 + √5

35. To find the solution to this problem, we need to add up all of the juice. 

5 3/4 + 4 1/2 + 2 3/4 = 13

The answer for this question would be C.


36. Since each square tile is 1 cm by 1 cm:

7 * 12 = 84
84/1 = 84

The answer is 84.

Caitlin recently rode her bicycle to visit her friend who lives 9 miles away. On her way
aniked [119]

Answer:

12 mph & 4 mph

Step-by-step explanation:

Let s and s - 8 be the speed of Caitlin going on her friend and her speed on her way home respectively.

Distance = Speed × Time

Distance/Speed = Time

9/s + 9/(s - 8) = 3

9(s - 8) + 9s = 3s(s - 8)

9s - 72 + 9s = 3s² - 24s

3s² - 42s + 72 = 0

s² - 14s + 24 = 0

(s - 2)(s - 12) = 0

s - 2 = 0

s = 2

s - 12 = 0

s = 12

If s = 2, then s - 8 = - 6 < 0. We want s and s - 8 to be positive so s = 12 mph. It follows that her speed on her way home is 4 mph.

PLEAE HELP ME OUT HURRY!!!
frutty [35]

Answer:

m = 123°

k = 57°

h = 123°

p = 99°

q = 81°

f = 99°

g = 81°

s = 42°

r = 57°

u = 57°

v = 123°

Step-by-step explanation:

<em>Using basic angle relationships, we should be able to tell these angles easily</em>.

If the 57° is supplementary to m, then m will be 180 - 57 = 123 degrees.

k is also supplementary to m, so k is 180-123=57 degrees - we also know this because it is an alternate interior angle to the other 57°.

h is an alternate interior angle to m, so h is the measure of m : 123°.

q is the same measure as the 81° angle, since they are corresponding angles. q is also 81°.

p is supplementary to q, so p is 180-81=99 degrees.

f is an alternate interior angle to p, so f is also 99°.

g is also an alternate interior angle to q, so g is 81°.

The measure of s will be 180-k-g since all 3 sides of a triangle add up to 180°: so 180-57-81=42 degrees.

r will be supplementary to the 81° angle and s, 42, so r is 180 - 81 - 42=57 degrees.

u is an alternate interior angle to r, so u is also 57 degrees.

v is supplementary to u, so v will be 180-57=123 degrees.

Hope this helped!
