The amount sabrina earns varies directly with the number boxes of cookies she sells.How much does Sabrina earn for eah box of cookies that she sells?

Earning (y) : ____ 5 ____ 10 ____ 15 ____ 20

Boxes sold (x) :__ 2 ____ 4 _____ 6 ____ 8

Answer:

$2.5

Step-by-step explanation:

Given:

Earning varies directly as the number of boxes of cookies sold

y α x

y = kx - - - (1)

k = constant of proportionality (earning per box of cookies sold)

Taking any 2 points :

y = 10 ; x = 4

10 = k4

10 = 4k

Divide both sides by 4

10/4 = 4k/4

2.5 = k

Hence, the amount earned per box of cookies sold is $2.5

Answer:

sin90° = 1.

Step-by-step explanation:

Using the diagram, we notice that the side opposite of the 90° angle is the hypotenuse itself.

Therefore sin90° = Hypotenuse/Hypotenuse = 1.

Answer:

x=-13

Step-by-step explanation:

divide 52 by -4 to get x=-13

Answer:

x = -13

Step-by-step explanation:

−4x = 52

Divide both sides by -4 to isolate the variable

-4x/-4 = 52/-4

x = - 13

Check:

Substitution

-4 (-13) = 52

52 = 52

* 2 negatives make a positive

Answer:

x = 37

Step-by-step explanation: Every angle in a triangle adds up to 180, so we can set up an equation where (x + 48) + (x + 58) = 180. From here, we can combine like terms to get 2x + 106 = 180. 180-106 is 74. 74 divided by 2 is 37. So, x = 37.

Answer:     Neptune is 34.64 times farther than Earth from the sun.

Step-by-step explanation:

Given: Distance from Earth to the sun is [tex]1.5\times10^8[/tex]  miles.

Distance from Earth to the sun is [tex]5.196\times10^9[/tex]  miles.

Number of times farther is it from Neptune to the sun= [tex]\dfrac{\text{distance from Neptune to the sun}}{\text{distance from Earth to the sun}}[/tex]

[tex]=\dfrac{5.196\times10^9}{1.5\times10^8}\\\\=\dfrac{5.196}{1.5}\times10^{9-8}\\\\= 3.464\times10=34.64[/tex]

Hence, Neptune is 34.64 times farther than Earth from the sun.

The comparison of the distances between Earth and Sun, and Neptune and Sun is needed.

Neptune is [tex]34.64[/tex] times the distance between Earth and Sun.

[tex]d_{es}[/tex] = Distance between Earth and Sun = [tex]1.5\times 10^8\ \text{miles}[/tex]

[tex]d_{ns}[/tex] = Distance between Neptune and Sun = [tex]5.196\times 10^{9}\ \text{miles}[/tex]

Dividing the given distances

[tex]\dfrac{d_{ns}}{d_{es}}=\dfrac{5.196\times 10^{9}}{1.5\times 10^8}\\\Rightarrow d_{ns}=34.64d_{es}[/tex]

4). [tex]-\frac{27}{28}[/tex]

5). Amount payable by the customer = 1416 Rs.

Step-by-step explanation:

4). [tex](\frac{3}{7})\times (-\frac{5}{8})\div (\frac{1}{3}\times \frac{5}{6})[/tex]

   = [tex](-\frac{15}{56})\div (\frac{5}{18})[/tex]

   = [tex](-\frac{15}{56})\times \frac{18}{5}[/tex]

   = [tex]-\frac{54}{56}[/tex]

   = [tex]-\frac{27}{28}[/tex]

5). Cost of the item = Rs 1200

   G.S.T. applicable on this item = 18%

   Amount to be paid for G.S.T.= 1200 × [tex]\frac{18}{100}[/tex]

                                                   = Rs 216

    Total amount payable by the customer = Cost + G.S.T.

                                                                      = 1200 + 216

                                                                      = Rs 1416

Answer:

F = 200/d^2

Step-by-step explanation:

F is inversely proportional to d^2

The equation is;

F = k/d^2

K = F•d^2

so to get k, we substitute the given values

K = 50 * 2^2

K = 50 * 4

K = 200

So we have that;

F * d^2 = 200

F = 200/d^2

Volume is a cubic measurement.

Set up a ratio of volume to the ratio of the height:

100/v2 = 2^3/5^3

V2 = 100 x 5^3/2^3 = 100 x 125/8 = 1,562.5 cubic feet

The volume of large pyramid is 1,562.5 cubic feet, by using ratio of heights.

What information do we have?

Ratio of heights of two similar pyramids = 2:5

Volume of smaller pyramid = 100 cubic feet

Volume of smaller pyramid / Volume of large pyramid = Height of smaller pyramid³ / Height of large pyramid³

100 / Volume of large pyramid = 2³ / 5³

Volume of large pyramid = 125(100) / 8

Volume of large pyramid = 1,562.5 cubic feet

____________________

[tex] \frac{45.4}{30} = \frac{180}{30} = 6[/tex]

We learnt this way in Turkey.

Answer: 6 problems in 4 minutes

Step-by-step explanation: If there are 45 problem and she can do them in 30 minutes, then you divide 45 by 30 to see how many problems she can do in one minute. 45 problems/30 minutes = 1.5 problems per minute. Then, you multiply 1.5 by 4, because you need to see the 4 minute mark, and 1.5 x 4 = 6. So, your answer is 6 problems.

The domain of the graph is:

-∞ <  x < ∞

Hence, option B is correct.

Step-by-step explanation:

We know that the domain of the function is the set of input or arguments for which the function is real and defined.

In other words,

From the given graph, we can easily observe that the graph extends horizontally to the left without bound, as well as to the right without bound.

Therefore, the domain of the graph is:

-∞ <  x < ∞

Answer:

x = 2, y = 6

Step-by-step explanation:

I'm assuming you're finding the pattern and then finding x and y, in which case it would be:

In the first one (x, 3, 4, 5, 6) you can see it goes up by 1 each time so x is just 2.

In the second one (y, 9, 12, 15, 18) it goes up by 3 each time so y = 9-3 = 6.
