Simplify the expression: 3(x + 3)

Answer:

Divide both to get the specific number of rolls which is 5

Step-by-step explanation: Notice that the angle diagonal

of the 114° is a vertical angle and vertical <'s are ≅.

Now, notice that we have two parallel lines cut by a transversal.

If two parallel lines are cut by a transversal, then

consecutive interior angles are supplementary.

So we can setup the equation 114 + y + 12 = 180.

Simplifying on the left gives us 126 + y = 180.

Now subtract 126 from both sides to get y = 54.

Answer:

P (34<X<39) = 0.5899

Step-by-step explanation:

When the distribution is normal, we use 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.

In this question, we have that:

[tex]\mu = 37, \sigma = 3[/tex]

What is the probability that a cat would return to it's dish between 34 and 39 times a day.

This is the pvalue of Z when X = 39 subtracted by the pvalue of Z when X = 34. So

X = 39

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

[tex]Z = \frac{39 - 37}{3}[/tex]

[tex]Z = 0.67[/tex]

[tex]Z = 0.67[/tex] has a pvalue of 0.7486

X = 34

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

[tex]Z = \frac{34 - 37}{3}[/tex]

[tex]Z = -1[/tex]

[tex]Z = -1[/tex] has a pvalue of 0.1587

0.7486 - 0.1587 = 0.5899

So

P (34<X<39) = 0.5899

Answer:

Tax on 2400 naira = 190 kobo

Step-by-step explanation:

Given that:

The first 500 naira is tax free.

Amount earned = 2400 naira

Amount to be taxed = 2400 - 500 = 1900 naira

Payable tax = 10 kobo on every naira

1 naira = 10 kobo

1900 naira = [tex]\frac{1900*10}{100}[/tex]

1900 naira = 190 kobo

Hence,

Tax on 2400 naira = 190 kobo

Answer:

Greenland offers the lowest unit rate, dollars per pound

Step-by-step explanation:

For McCoy, $4.5 = 5 pounds

Therefore $1 = 5pounds/4.5= 1.11 pounds

1 pound= 1/1.11= $0.9009

For Eat smart

$3=2 pounds

Therefore $1=2pounds/3 = 0.667 pounds

1 pound = 1/0.667= $1.499

For Greenland

$1/5= 1/4 pounds

$0.2=0.25 pounds

$1= 1.25 pounds

Therefore 1 pound= 1/1.25= $0.8

For Mother Nature

$0.95= 1 pound

Therefore Greenland offers the lowest unit rate at $0.8 per pound

Answer: Approximately d = 208.72

============================================================

Work Shown:

Make sure your calculator is in radian mode

A quick way to check is to compute cos(pi) and you should get -1

cos(angle) = adjacent/hypotenuse

cos(x) = 200/d

cos(0.29) = 200/d

d*cos(0.29) = 200

d = 200/cos(0.29)

d = 208.715135166392 which is approximate

d = 208.72

I rounded to two decimal places since x is rounded in that manner as well. Round however else you need if your teacher instructs.

Answer:

8 pounds

Step-by-step explanation:

8.75 / 3.5 = 2.5

20/2.5 = 8

Answer: 8 pounds of strawberries

Step-by-step explanation:

$8.75 - 3.5 pound

? - 1 pound

1 pound - 8.75 ÷ 3.5 = 2.5

$2.50 = 1 pound

$20.00 = ?

$20 = 20 ÷ 2.5 = 8

$20.00 = 8

Allison can buy 8 pounds of strawberries with $20.00

Hope that helped!

Answer:

Step-by-step explanation: So theres 10 marbles total in the bag. 5 is one half of 10 so the probability to get a blue marble is 5/10 or 1/2 and the probablility of getting an orange one is 1/10 so you have to first get lucky and get that 5/10 chance, and then get even more lucky and get the 1/10 chance and so I believe that it would be 1/20

Answer:

B. y=1/4x+2

Step-by-step explanation:

Equation of a Line

We are given a graph and we must select which of the proposed equations corresponds with the graph.

Let's identify two clear points in the graph. They are (0,2) and (4,3)

Substituting x=0 in the correct equation should give y=2. All the equations but C. give y=2 when x=0

Now when x=4, y should be 3.

Substituting in the each equation:

y=4x+2 = 4*4+2=18

y=1/4(4)+2=3

y=3x+2=3*4+2=14

The only equation that passes through both points is:

B. y=1/4x+2

Answer:

The equation best represents the relationship  between x and y in the graph is:

y =1/4x + 2

Hence, option B is correct.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Taking two points from the given graph

Determining the slope between (0, 2) and (4, 3)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [3 - 2] / [4 - 0]

               = 1 / 4            

Thus, the slope of the line = m = 1/4

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept b = 2

now substituting m = 1/4 and b = 2

y = mx+b

y =1/4x + 2

Therefore, the equation best represents the relationship  between x and y in the graph is:

y =1/4x + 2

Hence, option B is correct.
