Answer:

m ∠ M L N = 120

m < QLP =50

Step-by-step explanation:

Ray lq at 0 or 180,

ray lp at 50 or 130,

ray ol at 90,

ray ln at 60 or 120

and ray lm at 0 or 180

Lets substitute the values of the angles to check the given options

1) ∠ Q L P + m ∠ P L O =m< MLN+m< NLO m

50 +40= 120+30

90 is not equal to 150

2) m < QLO- m < QLP =m < MLO-m< MLN m

90-50 = 90-120

40 is not equal to 30

3) m< MLN\:=\:120  From the figure based on observation this is correct.

4) m < QLP =50   From the figure based on observation this is also correct.

Answer:

18 pieces

Step-by-step explanation:

This is a division problem.

1 m = 100 cm

To convert from cm to m we divide the length in cm by 100.

40 m + 50 cm = 40 m + 50/100 m = 40.5 m

The rope is 40.5 m long.

9/4 m = 2.25 m

Each piece is 2.25 m long.

[tex] \dfrac{40.5~m}{2.25~m} = 18 [/tex]

Answer: 18 pieces

Answer:

Mae used 1/4 of the whole bag on Wednesday.

Step-by-step explanation:

From the question, we understand that the fraction of the whole bag that Mae used on Monday is 3/4.

On Wednesday, we are then told that Mae uses 1/3 as much fruit as on Monday.  

This means that Mae uses 1/3 of the fruits she used on Monday. The fruits she used on Monday was actually 3/4 of the whole.

This means that on Wednesday, Mae used 1/3 of 3/4 fruits.

In Mathematics, the word "of" there stands for multiplication. Hence, Mae used 1/3 X 3/4 = 1/4 of the whole bag

Mae used 1/4 of the whole bag

d=√16+16 = √32=√2²*2²*2

d=4√2

Answer:

The mean will be (significantly) less.

Depending on the other items, the median is either affected only slightly or not at all.

Of all the answer choices, B is the correct one.

Step-by-step explanation:

So, we know that initially, Chucky had a total of 12 items. Each of the items has a different price, but the average cost of them is $7.41.

One item of the twelve was a wheel of cheese that costs $39.99.

And we want to know how the average cost and median cost will be affected if we remove this wheel of cheese.

The important thing to note here is that the average cost is $7.41. The wheel of cheese, however, costs $39.99. Thus, it is an outlier. It is significantly more expensive than the other items.

Initially, to find the mean, we had to add the 12 items together and then divide by 12. However, now that we removed the expensive outlier, the average cost will now be less.

Algebraically, we can see this. Let t be the total cost of the items excluding the cheese. Thus, the mean initially is:

[tex]7.41=\frac{t+39.99}{12}[/tex]

Find t. Multiply both sides by 12:

[tex]88.92=t+39.99\\t=48.93[/tex]

Therefore, all the other items excluding the cheese totals $48.93.

If we remove the cheese, the total is now $48.93 and with only 11 items. Thus, the mean is now:

[tex]48.93/11\approx\$4.45[/tex]

This is almost $3 less than the original mean. Thus, the mean has decreased significantly.

For the median, we really don't know. Recall that the median is simply the "middle" quantity. Assuming all the other products are similarly priced, the median may only change slightly or it may not at all. However, we can only guess for the median as it will depend on the prices of the other products. Nevertheless, it mostly likely decrease.

Edit: Added Letter Answer

Answer:

B

Step-by-step explanation:

Create a function to help determine his total cost.

12 x $7.41 = $88.92

After putting the cheese back he has 11 items and his total cost went down.

$88.92-$39.99 = $48.93

To find the average cost per item divide by 11.

$48.93/11 = $4.45 per item

The mean (average) has gone down.

The median would be the middle number, so you would need to line the cost of the items up from least to greatest. If you have an even number of items, you take the mean of the middle 2 numbers. The block of cheese would have have given Chucky 12 items so the 2 middle numbers would have been averaged.

A hypothetical 12 and 11 items:

$1  $2  $2  $3  $4  $4  $5  $6  $7  $7  $8  $39.99

Mean $7.42  Median $4.5

$1  $2  $2  $3  $4  $4  $5  $6  $7  $7  $8

Mean $4.45     Median $4

Taking the cheese away would move the middle down 1 number so it would also go down, but not as much as the mean of cost per item.

B. Both the mean and median will decrease, but the mean will decrease by more than the median.

Answer:

[tex]8\frac{37}{56}[/tex]

Step-by-step explanation:

[tex]12\frac{2}{7} + 3\frac{5}{8} = \frac{86}{7} + \frac{29}{8} = \frac{688 - 203}{56} = \frac{485}{56} = 8\frac{37}{56}[/tex]

Answer:

sin(B) =  [tex]\frac{15}{17}[/tex]

cos(B) = [tex]\frac{8}{17}[/tex]

tan(B) = [tex]\frac{15}{8}[/tex]

Step-by-step explanation:

I always find it easiest to model out the triangle: Angle B will be at the converging point of a and c.

Using SOH CAH TOA, we know that the Sin of an angle will be its opposite over hypotenuse. The opposite is 15, and the hypotenuse is 17.

So  [tex]\frac{15}{17}[/tex] is the sin of B.

We also know that the cosine of B will be it's adjacent over hypotenuse. The adjacent is 8 and the hypotenuse is 17, so

[tex]\frac{8}{17}[/tex]

Lastly, we know the tangent of B will be it's opposite over adjacent. The opposite of B is 15, and it's adjacent is 8, so

[tex]\frac{15}{8}[/tex] is the tangent of B.

Answer: r = 1 10/11

Step-by-step explanation: The quantities x and y are proportional.

The direct variation between {x] and {y} is discussed below.

Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -

y = Kx

K = y/x

where -

{K} is scale factor.

Given is that the quantities {x} and {y} are proportional.

The general equation of a straight line is -

y = mx + c

{m} - slope

{c} - intercept along the y - axis

The straight line graph also represents a direct variation between {x} and {y}. We can write -

m = (y - c)/x

Here the ratio of (y - c)/x is always constant.

So, we can write -

(y₁ - c)/x₁ = (y₂ - c)/x₂ = m = k

for c = 0, we can write -

y₁/x₁ = y₂/x₂ = m = k {constant}

Therefore, the direct variation between {x] and {y} is discussed above.

Answer:

Step-by-step explanation:

First we need to find inverse function of f(x) which is written in a form of (f(x))^(-1)

That means that we are actually looking for function f(y) and we need to solve this equation for "y"

y=(4x + 1)/3

3y = 4x + 1

4x = 3y - 1

x = (3y - 1) / 4

f(y) = (3y - 1)/4

Now we simply put the value of 3 instead of y and find the answer:

f(y=3) = (3*3-1)/4 = 2

Answer is 2

Answer:

C is the answer!!

Step-by-step explanation:

Answers:

a = 3

x intercept = -2

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

Explanation:

f(x) is the original function given. Let g(x) be the inverse of f(x).

To find the inverse, we first replace f(x) with y to get

y = (1/3)x-2

Afterward, we swap x and y to get

x = (1/3)y-2

From here, we must isolate or solve for y. To do so, add 2 to both sides and then multiply both sides by 3

x = (1/3)y-2

x+2 = (1/3)y

3(x+2) = y

y = 3(x+2)

g(x) = 3(x+2)

This explains where the x+2 comes from in the a(x+2) expression

The value of 'a' is therefore a = 3

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

To find the x intercept of the inverse, we replace g(x) with 0 and solve for x

g(x) = 3(x+2)

0 = 3(x+2)

0/3 = x+2

0 = x+2

x+2 = 0

x = 0-2

x = -2

The x intercept is x = -2. Plugging this x value into g(x) leads to g(x) = 0.

The g(x) graph crosses the x axis at x = -2.

Answer:

Step-by-step explanation:

So we have direct proportions here.

So

715=11

845=x

845*11/715

x=13

To check our work.

715/11=65

65*13=845.

Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/

So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.

Answer:

Step-by-step explanation:

1/2a+20=50

1/2a=30

a=10

Answer:

a= 60

Step-by-step explanation:

1/2a+2/3b=50, when b=30

Let's first subsitute 30 into b:

1/2a+2/3(30)=50

According to the order of operations, we must multiply 2/3 and 30 first.  So:

2/3 times 30 equals 20.

2/3 times 30/1.  3 goes into 30 ten times, so 2 times 10= 20.

Now we got:

1/2a+20=50

Since 20 and 50 are like terms, you want to geth those two together.  So, move the positive 20 to the other side where 50 is.  Since 20 got moved to the opposite side, it changes signs and becomes negative.

So:

1/2a=50-20        

50-20= 30

1/2a=30

Multiply each side by 2 because 2 is the only number that'll make the variable a just 1a.

1/2a times 2= 1a

30 times 2= 60, so:

1a= 60, which is also a= 60.

So a= 60.
