if 24 cards = $12, 1 card = $2 (24 / 12)

dozen = 12

if half of 24 is 12, and 24 cards cost $12, half of 12 is 6. same goes for the price. $12 / 2 = 6.

Answer:

y = 11

Step-by-step explanation:

A horizontal line passes through every single x - value, but only 1 y - value.

A vertical line hits every y-value and only 1 x-value.

The only y-value given is 11, so the equation is y = 11

-Chetan K

Answer:

x = 7.48

Step-by-step explanation:

You need to use the Pythagorean theorem to solve this problem.

leg^2 + leg^2 = hypotenuse^2

a^2 + b^2 = c^2

5^2 + x^2 = 9^2

25 + x^2 = 81

subtract 25 from both sides.

x^2 = 81 - 25

x^2 = 56

Square root both sides.

x = sqroot(56)

x = 7.48

Answer:  [tex]y = 3\sin\left(\frac{x}{3}\right)\right)+2\\\\[/tex]

This is the same as writing y = 3sin(x/3) + 2

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

Explanation:

The template for a sine function is

[tex]y = A\sin\left(B\left(x-C\right)\right)+D\\\\[/tex]

where,

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

The highest point is at y = 5 and lowest is at y = -1. This is a gap of 6 units, which cuts in half to 3. The amplitude is 3 meaning that A = 3.

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

One peak or highest point occurs when x = 3pi/2

The next peak over is at x = 15pi/2

This is a gap of (15pi/2) - (3pi/2) = 12pi/2 = 6pi units

The period is T = 6pi which leads to B = 2pi/T = 2pi/6pi = 1/3

In short, B = 1/3

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

We don't have to worry about the phase shift, so C = 0.

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

The midline is the average of the highest and lowest y values.

D = (5+(-1))/2 = 4/2 = 2

This means D = 2.

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

In the previous sections, we found the following

This means we go from

[tex]y = A\sin\left(B\left(x-C\right)\right)+D\\\\[/tex]

to

[tex]y = 3\sin\left(\frac{1}{3}\left(x-0\right)\right)+2\\\\y = 3\sin\left(\frac{x}{3}\right)\right)+2\\\\[/tex]

which is the final answer.

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

Extra info:

If you wanted, you could use a cosine function. This is because any cosine function is a phase shift of a sine function. But that greatly complicates things and sine is better suited here.

Answer: x = 120 y = 25 z = 35

Step-by-step explanation:

z = 35 because of the Z rule

y = 25 because y + 35 = 60

x = 120 because of the C rule

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

Explanation:

Focus on the first row only. We won't worry about the other stocks.

Convert each of the percentages to decimal form

Then multiply those decimal values with their respective gains or losses.

Use a negative sign to indicate losses.

The last step is to add up each of the results to get the expected value.

-10+0.75+20.25 = 11

The result is positive, so it's a gain rather than a loss.

On average, we expect an $11 gain for stock ABC.

Answer: 1. 55 ft   2. 10 ft. 3.3 in.

Step-by-step explanation:

For question 9, you need to understand that the angle on the left is equal to the one on the right from the mirror priniciple. Now let's say the height of the dinosaur is x ft. We would get the equation 5.5/4 = x/40 and we get that x is 55, thus the height of the dinosaur is 55 ft

For question 10, we use the same similarity principle as we use in question 9 so given that the height of the light pole is h in. we get the equation

h/185 = 62/93

So, h is 123.33(I used a calculator, hope that's fine). Thus the height of the light pole would be 123.33 in. or 10 ft. 3.3 in.

Hope this helps!!!!

The number of turtles they will have after 6 months is =1,893 turtles

Number of turtles owned by Liz every month =

first month = 7

second month= 7×3 = 21

third month = 21× 3 = 63

fourth month = 63 × 3 = 189

Fifth month = 189 × 3 = 567

Sixth month = 567 × 3 = 1701 turtles

Number of turtles owned by Steven every month =

first month = 6

second month = 6 × 2 = 12

third month = 12× 2 = 24

Fourth month = 24 × 2 = 48

Fifth month = 48 × 2 = 96

Sixth month = 192 turtles

Therefore total turtle owned by both Liz and Steven=

1701 + 192 = 1,893 turtles

Answer:

30

Step-by-step explanation:

Since we have five numbers and their mean is 16 as we all know that  

mean = summation of total numbers / summation of  total number of terms

Mean = 16 for 5 numbers

sum =  16 x 5 = 80( sum of the  five terms)

when two extra numbers are added, it then becomes 7 numbers . since the numbers are unknown we then represent each numbers with the X and Y

New sum = 80 + x + y

new number of terms = 7

new mean = 20

20 =  80 + x + y

             7                    we cross multiply to get the unknown values

20 x 7  =  80 +  x + y    ,   140  = 80 + x + y

we use y as subject of the formula to get x

140 - 80 + x =  y

60 +  x = y,   y = 60 + x

we input y = 60 + x into the equation (140= 80 + x + y) to get x

140 = 80 + x  + 60 + x    ,        140 = 80 + 60 + x  + x

140  =  140 + 2x   ,         140 -140  = 2x

0 = 2x   ,  divide both sides by 2 to get x

x = 0

we then input x = 0 into the equation to get y

140 - 80 + x = y

140 - 80 + 0 = y   ,      60 + 0 = y

y  =  60

To find the mean of the two extra numbers,  we then use the above formula for finding mean.

60 + 0 / 2   =  60 / 2 =30

mean = 30.

Answer:

-96

Step-by-step explanation:

when there are two subtraction signs it is basically a plus sign

so

___ + 99 = 3

then you can subtract 99 from both sides

___ = -96

your answer is -96

Answer:

  93

Step-by-step explanation:

Add 36 to both sides of the equation:

  36 -36 + ___ = 36 +57

  0 + ___ = 93

  ___ = 93

The integer 93 goes in the blank.

Answer:Answer:

"For 75 g butter ≈ 27 fingers

Step-by-step explanation:

Using unitary method

For 20 fingers = 55 g butter

For 1 g butter = 20/55 fingers

=> For 1 g butter = 4/11 fingers (Simplified form)

Multiplying both sides by 75

=> for 75 g butter =

=> For 75 g butter ≈ 27 fingers ( approximately )"

Answer:

Although it would be great to see the picture of your problem, Acute angles are usually smaller than a right angle. A right angle is half of a straight line. A straight line is exactly how it sounds. An obsute angle is bigger than a right angle, so it has a higher degree.

The phrase "no more than" implies upper limit. The correct choice for food budget is: Option D. No more than $60 can be spent on food.

Suppose that you had initial amount as A.

Let you deduce B, C, and D from it.

The remaining amount is obtained by subtraction.

Thus,

Remaining amount  = A - (B + C + D) = A - B - C - D

For the given case, the budget left for food is the remaining amount after all the expenses are reduced from the income.

Income = $750

Expenses except food: $20 + $75 + $85 + $260 + $250 = $690

Thus, budget left is $750 - $690 = $60

This remaining budget is left. The person can spent either full of it on food or less than it, but cannot spend more than it as that person doesn't have more than $60 left.

Thus:

Food budget is no more than $60.

or

Food budget ≤ $60

Thus,

The correct choice for food budget is: Option D. No more than $60 can be spent on food.

Answer:  46 degrees

Explanation:

Angle PRS = 98 degrees

The two smaller pieces add up to this larger angle, so,

(anglePRQ) + (angleQRS) = angle PRS

(3x-8) + (2x+6) = 98

5x-2 = 98

5x = 98+2

5x = 100

x = 100/5

x = 20

Then we can find each angle

Notice how 52+46 = 98 to confirm the answers.
