Answer:

72 cupcakes

Step-by-step explanation:

Morgan can make 4 cupcakes with one cup of flour. She has 18 cups of flour and suppose she can make x cupcakes, then

1 cup of flour - 4 cupcakes

18 cups of flour - x cupcakes

Write a proportion:

$\dfrac{1}{18}=\dfrac{4}{x}$

Cross multiply:

$1\cdot x=18\cdot 4\\ \\x=72\ cupcakes$

Triangle 1 has an angle that measures 34° and an angle that measures 48°. Triangle 2 has an angle that measures 34° and an angle

ira [324]

Answer:

the value of x would be 108 degrees

Step-by-step explanation:

The computation of the value of x in degrees is shown below:

Given that both the triangles has the 34 degrees and 48 degrees

Now in the triangle 1 angle a = 108 degrees

And, in the triangle 2 a = x

Now in this case both the triangles are similar to each other

So here the value of x would be 108 degrees

Ana drew a map of the Panama Canal. In the scale Ana used for the map, 4 centimeters represents 20 kilometers. The actual length

yawa3891 [41]

Answer:

Length of the canal on the map is 16.4 centimeters.

Step-by-step explanation:

If actual length of Panama Canal = 20 kilometers

and length of the canal on map = 4 centimeters

Then scale factor = $\frac{\text{Length of canal on map}}{\text{Actual length of canal}}$

= $\frac{4}{20}$

= $\frac{1}{5}$

If the actual length of Panama Canal = 82 kilometers

Then the length of canal on the map = Actual length × Scale factor

= $82\times \frac{1}{5}$

= 16.4 centimeters

Therefore, length of the canal on the map is 16.4 centimeters.

Suppose that prices of recently sold homes in one neighborhood have a mean of $225,000 with a standard deviation of $6700. Using

elena55 [62]

Answer:

$211600 = 225000 -k*6700$

$k = \frac{225000-211600}{6700}= 2$

$238400 = 225000 +k*6700$

$k = \frac{238400-225000}{6700}= 2$

So then the % expected would be:

$1- \frac{1}{2^2}= 1- 0.25 =0.75$

So then the answer would be 75%

Step-by-step explanation:

For this case we have the following info given:

$\mu = 225000$ represent the true mean

$\sigma =6700$ represent the true deviation

And for this case we want to find the minimum percentage of sold homes between $211,600 and $238,400.

From the chebysev theorem we know that we have $1 -\frac{1}{k^2}$ % of values within $\mu \pm k\sigma$ if we use this formula and the limit given we have:

$211600 = 225000 -k*6700$

$k = \frac{225000-211600}{6700}= 2$

$238400 = 225000 +k*6700$

$k = \frac{238400-225000}{6700}= 2$

So then the % expected would be:

$1- \frac{1}{2^2}= 1- 0.25 =0.75$

So then the answer would be 75%
