The exchange rate in some prehistoric village was 6 jagged rocks for every 2 smooth pebbles. Also, one shiny rock could be traded for 3 smooth pebbles. If Joaquin has 30 jagged rocks, what is the maximum number of shiny rocks he could trade for?

A. 6
B. 4
C. 5
D. 3

Answers

Answer 1

30 Jagged rocks are the same 3 shiny rocks using the exchange rates provided(i.e. option D)

What is an exchange rate?

Exchange rate means the rate at which one item exchanges hands with another, for instance, in this case, 6 jagged rocks are equivalent to 2 smooth pebbles.

6 jagged rocks=2 smooth pebbles

divide both sides by 2

6/2 jagged rocks=2/2 smooth pebbles

3 jagged rocks=1 smooth pebble

We can rewrite as below:

1 jagged rock=1/3 smooth pebble

30jagged rocks=1/3*30 smooth pebbles

30 jagged rocks=10 smooth pebbles

Now we need to convert 10 smooth pebbles to shiny rock equivalence

3 smooth pebbles=1 shiny rock

1 smooth pebble=1/3 shiny rock

10 smooth pebbles=1/3*10 shiny rocks

10 smooth pebbles=3 shiny rocks( even though it is 3.33, but the final answer should be rounded to a whole number)

Answer:

Socko gained 3/5 kg from month 1 to month 2.

Step-by-step explanation:

Socko mass was 3/10 kg in month 1 and 9/10 kg in month 2.

The amount of mass he gained is k.

3/10 + k = 9/10

Subtract 3/10 from both sides.

k = 6/10

Reduce the fraction.

k = 3/5

Answer: Socko gained 3/5 kg from month 1 to month 2.

In triangle ABC , M and N are midpoints of sides. If MN = 2x + 5 and BC = x2 − 2, find the possible lengths for MN.
A. 17
B. 6 and 2
C. 1 and 17
D. 2 and 34

Answers

Answer:

A.17

Step-by-step explanation:

The possible lengths for MN are 17 and 1, so the correct answer is C. 1 and 17

How to get the lengths

Since MN = 2x + 5 and BC = x^2 − 2, we can write the equation

[tex]2x + 5 = (1/2)(x^2 - 2)[/tex]

Solving for x, we get:

[tex]2x + 5 = (1/2)(x^2 - 2)[/tex]

[tex]4x + 10 = x^2 - 2[/tex]

0 = [tex]x^2- 4x-12[/tex]

0 = (x - 6)(x + 2)

This equation has two solutions: x = 6 and x = -2.

Substituting these values into the expression for MN, we find that MN can have two possible lengths:

MN = 2(6) + 5 = 17 or

MN = 2(-2) + 5 = 1.

Therefore, the possible lengths for MN are 17 and 1, so the correct answer is 17 and 1.

Solve for r 5r^2+5=130

Answers

Answer:

Simplifying

5r2 + 5 = 130

Reorder the terms:

5 + 5r2 = 130

Solving

5 + 5r2 = 130

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-5' to each side of the equation.

5 + -5 + 5r2 = 130 + -5

Combine like terms: 5 + -5 = 0

0 + 5r2 = 130 + -5

5r2 = 130 + -5

Combine like terms: 130 + -5 = 125

5r2 = 125

Divide each side by '5'.

r2 = 25

Simplifying

r2 = 25

Take the square root of each side:

r = {-5, 5

Melanie purchases 6 basketballs and 2 volleyballs for $114. A volleyball cost her $3 less than a basketball. How much did each volleyball cost?

Answers

Answer:

a volleyball is $16.5

Step-by-step explanation:

6b+2v= 114

v=b-3

6b+2(b-3)= 114

6b + 2b - 6

8b - 6 = 114

8b = 108

b= 13.5

substitute b in

6(13.5) + 2v = 114

81 + 2v = 114

2v = 33

v= 16.5

A normal distribution has a mean of 15 and a standard deviation of 2. Find the value that corresponds to the 75th percentile.

Answers

Answer:

The value that corresponds to the 75th percentile is 16.35.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

A normal distribution has a mean of 15 and a standard deviation of 2.

This means that [tex]\mu = 15, \sigma = 2[/tex]

Find the value that corresponds to the 75th percentile.

This is X when Z has a pvalue of 0.75. So X when [tex]Z = 0.675[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 15}{2}[/tex]

[tex]X - 15 = 2*0.675[/tex]

[tex]X = 2*0.675 + 15[/tex]

[tex]X = 16.35[/tex]

The value that corresponds to the 75th percentile is 16.35.
