u = 8

Step-by-step explanation:

log(10) u = log(10) 4^(3/2)

or

u = 4^(3/2)

= [sqrt(4)]^3

= (2)^3

= 8

Answer:

$208

Step-by-step explanation:

First, divide.

80 ÷ 5 = 16

Next, multiply.

16 × 13 = 208

Lastly, have a wonderful day! :)

Answer:

At the same rate, Latoya would make $208 for 13 hours of work.

Step-by-step explanation:

Since Latoya made $80 for 5 hours of work, that means she made a unit rate of $16 per hour. By working at the same rate for 13 hours, she would make a total of [tex]16 * 13 =[/tex] $208.

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

Since the scale is in equilibrium, both sides must be equal. Therefore, we have the following equation:

[tex][\text{Left Side} ]3x+3=[\text{Right Side}]9[/tex]

Solving for [tex]x[/tex]:

[tex]3x+3=9,\\3x=6,\\x=\boxed{2}[/tex]

Answer:x=2

Step-by-step explanation: try to first set up an equation. First we can see the scale is balanced so we know each side is equal to each other. You have 3 x boxes and 3 circles so our first side will be 3x+3. Now let’s move onto the second side. It has 9 circles so 3x+3=9. Now let’s solve!

Subtract 3

3x=6

Now divide by 3

X=2

Answer:

2x= 38.5

Step-by-step explanation:

I'm not sure where u got 12x but 2 x = 38.5:

2x + 5 =82

subtract 5 for 82

2x = 77

77 divided by 2 is 38.5

x = 38.5

hope this helps :)

Answer:

Elimination

x = 2

y = -2

Step-by-step explanation:

Elimination

2x + 4y = -4

2x - y = 6

Subtract the second equation from the first

5y = -10

Divide both sides by 5

y = -2

---------------------

Substitute for y = -2 in the second equation

2x - -2 = 6

2x + 2 = 6

subtract 2 from both sides

2x = 4

Divide both sides by 2

x = 2

Answer: 990 ways

Step-by-step explanation:

For the first chicken, there are 11 slots it could be, or 11.  For the next chicken, there are 10 available, or 10.  Same thing for the third chicken, with 9.  Thus, simply do 11*10*9 to get 990.

Answer:

6.4 cm

Step-by-step explanation:

i think you'd use pythagoras theorem if you don't know any of the angles . a^2 + b^2 = c^2 . so 4^2 + 5^2 = square root 41 ,, = 6.403124237 cm

i apologise if it is incorrect ^^

Answer:

The teacher can make 8 different 3 person teams

Step-by-step explanation:

Since there is a total of 24 students and the teacher wants to make as many 3 person groups as he/she can you would just do 24 divided by 3 which would equal 8 different teams of 3 people. So the teacher can make 8 different groups of 3 people

Answer:

The probability that his bill will be less than $50 a month or more than $150 for a single month is 0.3728 = 37.28%.

Step-by-step explanation:

Normal Probability Distribution:

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

A salesman who uses his car extensively finds that his gasoline bills average $125.32 per month with a standard deviation of $49.51.

This means that [tex]\mu = 125.32, \sigma = 49.51[/tex]

Less than 50:

p-value of Z when X = 50. So

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

[tex]Z = \frac{50 - 125.32}{49.51}[/tex]

[tex]Z = -1.52[/tex]

[tex]Z = -1.52[/tex] has a p-value of 0.0643

More than 150

1 subtracted by the p-value of Z when X = 150. So

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

[tex]Z = \frac{150 - 125.32}{49.51}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a p-value of 0.6915

1 - 0.6915 = 0.3085

The probability that his bill will be less than $50 a month or more than $150 for a single month is:

0.0643 + 0.3085 = 0.3728

The probability that his bill will be less than $50 a month or more than $150 for a single month is 0.3728 = 37.28%.

Answer:

  3.  C(−1, −5), D(2, −5)

Step-by-step explanation:

The given points are 2 -(-1) = 3 units apart horizontally, so the remaining points will need to be 18/3 = 6 units below, vertically. Translating the given points down 6 gives ...

  D = A -(0, 6) = (2, 1) -(0, 6) = (2, -5)

  C = B -(0, 6) = (-1, 1) -(0, 6) = (-1, -5)

The two points required to make a rectangle with an area of 18 square units are ...

  C(-1, -5), D(2, -5)

_____

The area of a rectangle is the product of length and width. If the area is 18 square units, and the width is 3 units, then the length must be 6 units. 3×6=18.

Step-by-step explanation:

common ratio r = 98/140

first term a = 140

geometric sequence formula is an = ar^(n-1)

an = 98^(n-1)

where n is the number of terms in the sequence
