What radius of a circle is 2.6 cm. Find the circumference to the nearest tenth.

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:

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: 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:

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:give them a 100$ bill and ask for change

Step-by-step explanation:

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:

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.

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

first you have to see the triangle BCD

then hypotheses and perpendicular are given so you have to find base

after finding base. In rectangle ABCD DC is length and BC is breadth so now you can find area by using the formula A = l×b
