write fractions for each type of song out of the total

10/45 country

15/45 pop

5/45 r&b

10/45 rap

5/45 techno

write these fractions in their simplest forms

2/9 country

1/3 pop

1/9 r&b

2/9 rap

1/9 techno

<em>the chances of the next song played on shuffle being pop is 15/45, or 1/3</em>

Answer:

correct answer is \frac{1}{3}

Step-by-step explanation:

Total number of song which include country song, pop song, R &B song, rap song and techno song is 45

Therefore total number of POSSIBLE outcome is 45

outcomes of having pop song =  15

On reshuffle probability of pop song is\frac{15}{45} = \frac{1}{3}

therefore correct answer is \frac{1}{3}

4. A number m is such that when it is divided by 30, 36, and 45 the remainder is always 7,
Bezzdna [24]

Answer:

187

Step-by-step explanation:

A number m is such that when it is divided by 30, 36 and 45 the remainder is always 7.

We should first find the LCM of 30, 36 and 45

We get that the LCM of the three numbers is 280 (working attached).

So now;

\frac{180}{30} = 6

\frac{180}{36} = 5

\frac{180}{45} = 4

But we need a number that leaves a remainder of 7 so we add 7 to 180 to get; 180 + 7 = 187.

5. Katie makes and sells scarves. Her monthly profit is given by P(s) = -s2 + 25s - 100, where "s" is the selling price. For wha
Marat540 [252]

Answer: s > 5

Step-by-step explanation:

-s² + 25s - 100 > 0

Coefficient of s² is -1, multiply the equation through by -1.

-1 × (-s² + 25s - 100)

s² — 25s + 100

ax² + bx + c

Then you get the factors x and y that gives x + y = b and xy = c

b = -25 and c = 100, x = -20 and y = -5

-20 × -5 = 100 and -20 + -5 = -25

Then

s² — 20s — 5s + 100 > 0

Factorising,

s (s — 20) — 5(s — 20) > 0

(s — 5)(s — 20) > 0

(s — 5) > 0 and (s — 20) > 0

s>5 and s>20

s > 5

Hope this Helps?

Can anyone help me answer this question (find x)? (15 points)
Greeley [361]

Answer:

The answer to your question is x = 6

Step-by-step explanation:

Process

1.- We can prove that the triangles are congruent.

Two angles measure the same 23°

Two sides measure the same 9

Two angles measure the same the are vertical angles

The third angle measure the same

From this information, we conclude that the triangles are congruent  ASA

2.- If the triangles are congruent then x = 6, the sides are congruent

4<br> Simplify.<br> Rewrite the expression in the form b".<br> 610<br> 66<br> -
m_a_m_a [10]

Applying the division rule of exponents, 6^10/6^6 can be rewritten in the form of b^n as: 6^10/6^6 =  6^4.

<h3>What is the Division Rule of Exponents?</h3>

The division rule of exponents state that if we have a numerator and a denominator with the same base, the quotient will be the base, while we subtract the exponent value of the denominator from the exponent value of the numerator.

For example, if we have, a³/a², the division rule of exponents states that:

a^(3 - 2) = a^1 = a.

Given the expression, 6^10/6^6, we can rewrite the expression in the form of b^n by applying the division rule of exponents as shown below:

6^10/6^6 = 6^(10 - 6)

6^10/6^6 =  6^4

In conclusion, applying the division rule of exponents, 6^10/6^6 can be rewritten in the form of b^n as: 6^10/6^6 =  6^4.
