Answer:

1. x=6

2. C <-26

3. p<6

4. -5x-44

Step-by-step explanation:

1. 2x = 3(x-2) - 3(x-6)

Distribute

2x= 3x-6 -3x+18

Combine like terms

2x =12

Divide by 2

2x/2 =12/2

x=6

2. C+6<-20

Subtract 6 from each side

C+6-6 < -20-6

C <-26

3. -5p > -30

Divide by -5. Remember to flip the inequality when dividing by a negative

-5p/-5 < -30/-5

p<6

4. -4 - 5(X+8)

Distribute

-4 -5x-40

Combine like terms

-5x-44

An acute angle θ is in a right triangle with sin θ = eight ninths. What is the value of cot θ? nine divided by the square root o

snow_lady [41]

Answer:

$\frac{\sqrt{17} }{9}$

Step-by-step explanation:

a^2 +b^2 =c^2 Use pythagorean theorem

8^2 +b^2 =9^2 Substitute in your known values

b= $\sqrt{17} , -\sqrt{17}$

b= $\sqrt{17}$ A triangle leg cannot be a negative length

$\frac{\sqrt{17} }{9}$ Find cosine of angle theta.

If X=20°, Y=135°, what will Z be

Veronika [31]

The value of Z would be 225°

<h3>What is the angle at a point?</h3>

The angle at a point are angles that add up to 360°

Thus, X + Y + Z = 360°

X = 20°

Y = 135°

Then, Z = 360° - X - Y

Z = 360° - 20° + 135°

Z = 360° - 155°

Z = 205°

Therefore, the value of Z is 205°

Bananas are being sold for $0.59 a pound at Store A and $0.55 a pound at Store B. A customer wants to buy 10 pounds of bananas.

andre [41]

Answer:

The customer saves 5.9 - 5.5 = $0.5

when he shops at store B

Step-by-step explanation:

Stores A and B sells bananas at different prices per pound.

Bananas are being sold for $0.59 a pound at Store A and $0.55 a pound at Store B.

If a customer wants to buy 10 pounds of bananas from store A and store B,

The customer would spend 0.59 × 10 pounds of bananas = $5.9

buying from store A and

The customer would spend 0.55 × 10 pounds of bananas = $5.5

buying from store B.

The customer spends more for 10 pounds of bananas if he buys from shop A.

The customer saves 5.9 - 5.5 = $0.5

when he shops at store B

Helene claimed that the expected value when rolling a fair die was 3.5. Steve said that wasn't possible. He said that the expect

Nesterboy [21]

Answer:

Helene is right

Step-by-step explanation:

Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:

x = ∑ p *i,

where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.

Now, for the case of a dice, the expected value would be:

x = 1 * $\frac{1}{6}$ + 2 * $\frac{1}{6}$ + 3 * $\frac{1}{6}$ + 4 * $\frac{1}{6}$ + 5* $\frac{1}{6}$ + 6 * $\frac{1}{6}$ ,

as every outcome has the same chance of happenning. Solving we get that:

x= $\frac{1}{6}$ *(1 +2 +3 +4+5+6) = $\frac{1}{6}$ * 21 = 3.5

Helene is right.
