Correct question is;
Which of these expressions is equivalent to log (9^2)?
Answer:
D: 2•log 9
Step-by-step explanation:
From log rules, we know that;
log(a^n) = n•log(a)
Applying that rule to this question, we can simplify log (9^2) as;
log (9^2) = 2•log 9
Looking at the options, the correct one is Option D
Caleb cut a rope into 4 pieces. The lengths of the pieces of rope are 5 2/8 inches, 7 7/8 inches, 4 1/8 inches, and 3 3/8 inches. Which choice is the closest estimate of the length of the original rope
Answer:
the actual answer is 20.625 and since there aren't any choices I'll give u my estimated answer: 20
Step-by-step explanation:
I got my estimated answer by rounding each length of rope down or up according to if it was less than 4/8 or higher. example: rounded 7 7/8 to 8

Suppose you know the total cost of the gas but do not know the price per gallon.
Explain how you would work backward to find the cost per gallon.
9514 1404 393
Answer:
price per gallon = (total cost)/(number of gallons)
Step-by-step explanation:
Price per gallon is found by dividing the price by the number of gallons:
price per gallon = (total cost)/(number of gallons)

40% of 350 is 140
7% of 140 is 9.8
A glassblower can produce several sets of simple glasses in about 3 hours. When the glassblower works with
an apprentice, the job takes about 2 hours. Write an equation that can be used to find the amount of time t, in
hours, it would take for the apprentice to make the same number of sets of glasses when working alone.
Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are:
Glassblower: 1/3.Apprentice: 1/x.Together: 1/2.Hence, applying the equation for the together rate:
[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]
[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]
[tex]2x + 6 = 3x[/tex]
[tex]x = 6[/tex]
It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

Answer:
1) 27.374
2)9.177
Step-by-step explanation:
1) To get the value of x , we use the appropriate trigonometric ratio
From what we are given;
we have the hypotenuse ( the side facing the right angle) and the adjacent
The trigonometric identity to use here is the cos
The cos of an angle is the ratio of the adjacent to the hypotenuse
cos 64 = 12/x
x = 12/cos 64
x = 27.374
2) Here, we are given the hypotenuse and the opposite
The trigonometric ratio to use here is the sine
the sine of an angle is the ratio of the opposite to the hypotenuse
thus, we have it that;
sin 35 = x/16
x = 16 sin 35
x = 9.177

A tree casts a shadow 31 feet long when the angle of
elevation of the sun is 58º. Find the height of the tree.
Answer:
x=24.2198542
ROUND IF NEEDED
Step-by-step explanation:
We are trying to find the height of the tree or the vertical side
We are given
The angle of elevation or the angle at the ground ,38The horizontal length, 31.Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle
we are going to use tangent
[tex] \tan(x) = \frac{opp}{adj} [/tex]
plug 38 in for x or theta, x for opp side and 31 for adjacent side
[tex] \tan(38) = \frac{x}{31} [/tex]
Multiply 31 by both sides to find x
x=24.2198542
ROUND IF NEEDED.
divide 600 in the ratio 2: 3: 4
Answer:
133.33, 200, 266.66
Step-by-step explanation:
GIven data
This is a ratio problem, and we will use the part to all method to get the solution
The given ratio is
= 2: 3: 4
the total ratio
=2+3+4
=9
Hence the first part is
2/9= x/600
cross multiply
9x= 1200
x= 1200/9
x= 133.33
The second part
3/9=x/600
1/3=x/600
3x=600
x=200
The third part
4/9=x/600
4/9=x/600
9x=600*4
9x=2400
x=2400/9
x=266.66
Therefore the figures are
133.33, 200, 266.66

If 400,000 tourists contribute $67 million to a local economy, how much would 600,000 tourists contribute?
Answer:
[tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
Step-by-step explanation:
Given that,
400,000 tourists contribute $67 million to the local economy.
We need to find how much would 600,000 tourists contribute.
400,000 tourists = $67 million
1 tourist = [tex](\dfrac{67}{400,000 })\ \text{million}[/tex]
So, 600,000 tourists contribution is :
[tex]600000\ \text{tourists}=(\dfrac{67}{400,000 })\times 600000\ \text{million}\\\\=100.5\ \text{million}[/tex]
Hence, [tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.
which of the following is NOT a characteristic of a parallelogram
Answer:
If all the points do not connect then you do not have a parallelogram. If all of the sides are not of equal length, them being parallel than this is not a parallelogram. Opposite edges and angles have to be congruent for it to be a parallelogram.

There is 5 yellow 3 red 4 green 2 blue and 2 white what is the probability of picking white then green
Answer:
2 (I think)
Step-by-step explanation:
4-2=2
Answer:
1/30
Step-by-step explanation:
the probability of picking white is 2/16 simplified to 1/8
the probability of picking a green would equal to 4/15
notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.
you would then multiply
1/8 x 4/15
= 4/120
simplified to
1/30
