What is M angle FAD?

Answer:

26

Step-by-step explanation:

15 3/5=78/5

(78/5)/(3/5)=(78/5)(5/3)=78/3=26

There are 26 three-fifths in fifteen and three-fifths.

To find out how many times [tex]\frac{3}{5}[/tex] is in [tex]15 \frac{3}{5}[/tex], we follow these steps:

Convert the mixed number [tex]15 \frac{3}{5}[/tex] into an improper fraction.

[tex]15 \frac{3}{5} = 15 + \frac{3}{5} = \frac{15 \times 5}{5} + \frac{3}{5} = \frac{75}{5} + \frac{3}{5} = \frac{75 + 3}{5} = \frac{78}{5}[/tex]

Divide [tex]\frac{78}{5}[/tex] by [tex]\frac{3}{5}[/tex].

To divide fractions, we multiply by the reciprocal:

[tex]\frac{78}{5} \div \frac{3}{5} = \frac{78}{5} \times \frac{5}{3} = \frac{78 \times 5}{5 \times 3} = \frac{390}{15}[/tex]

Simplify [tex]\frac{390}{15}[/tex].

Divide the numerator and the denominator by their greatest common divisor (GCD), which is 15:

[tex]\frac{390 \div 15}{15 \div 15} = \frac{26}{1} = 26[/tex]

Using the normal distribution, it is found that:

a) 64.8% of years will have an annual rainfall of less than 44 inches.

b) 68.4% of years will have an annual rainfall of more than 39 inches.

c) 31.1% of years will have an annual rainfall of between 37 inches and 42 inches.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item a:

The proportion is the p-value of Z when X = 44, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{44 - 41.8}{5.8}[/tex]

[tex]Z = 0.38[/tex]

[tex]Z = 0.38[/tex] has a p-value of 0.648.

0.648 x 100% = 64.8%

64.8% of years will have an annual rainfall of less than 44 inches.

Item b:

The proportion is 1 subtracted by the p-value of Z when X = 39, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{39 - 41.8}{5.8}[/tex]

[tex]Z = -0.48[/tex]

[tex]Z = -0.48[/tex] has a p-value of 0.316.

1 - 0.316 = 0.684

0.684 x 100% = 68.4%

68.4% of years will have an annual rainfall of more than 39 inches.

Item c:

The proportion is the p-value of Z when X = 42 subtracted by the p-value of Z when X = 37, hence:

X = 42:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{42 - 41.8}{5.8}[/tex]

[tex]Z = 0.035[/tex]

[tex]Z = 0.035[/tex] has a p-value of 0.514.

X = 37:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{37 - 41.8}{5.8}[/tex]

[tex]Z = -0.83[/tex]

[tex]Z = -0.83[/tex] has a p-value of 0.203.

0.514 - 0.203 = 0.311

0.311 x 100% = 31.1%

31.1% of years will have an annual rainfall of between 37 inches and 42 inches.

A similar problem is given at https://brainly.com/question/24663213

To calculate the percentage of years with an annual rainfall between 37 inches and 42 inches, we need to use the standard normal distribution. First, we can convert the rainfall values to z-scores, and then use a z-table or calculator to find the area under the curve between the corresponding z-scores.

To calculate the percentage of years with an annual rainfall between 37 inches and 42 inches, we need to use the standard normal distribution. First, we can convert the rainfall values to z-scores using the formula:

z = (x-mu)/sigma.

So, for 37 inches, the z-score is (37-41.8)/5.8 = -0.8276, and for 42 inches, the z-score is (42-41.8)/5.8 = 0.0345.

Now, we can use a z-table or calculator to find the area under the curve between these two z-scores. The percentage of years with an annual rainfall between 37 inches and 42 inches is the difference between these two areas.

The equation of given line 8x-4y=5 and it is dilated by a scale factor of 8 centered at the origin.

Step 1 : Find two points on given line.

When x=0, y=?

[tex]8x-4y=5[/tex]

[tex]8(0)-4y=5[/tex]

[tex]y=\frac{-5}{4}[/tex]

When y=0, x=?

[tex]8x-4y=5[/tex]

[tex]8x-4(0)=5[/tex]

[tex]x=\frac{5}{8}[/tex]

We get points [tex]A(0,\frac{-5}{4}), B(\frac{5}{8},0)[/tex]

Step 2: Find distance from centered and scale it.

Now, It is said that line 8x-4y=5 dilated by a scale factor of 8 centered at the origin and point A and point B is on same.

So that point A and point B  will also get dilated by a scale factor of 8 centered at the origin or distance of points from origin will be scaled by 8.

For point A:

Distance of point [tex]A(0,\frac{-5}{4})[/tex] from origin is [tex]( \frac{-5}{4})[/tex]  unit in x-direction and zero [tex]\frac{-5}{4})[/tex]  unit in y-direction.

After scaled by factor of 8, the distance will multipy by 8 and new location is [tex]A'(0,-10)[/tex]

For point B:

Distance of point [tex]B(\frac{5}{8},0)[/tex] from origin is [tex](\frac{5}{8})[/tex] unit in x-direction and zero unit in y-direction.

After scaled by factor of 8, the distance will multipy by 8 and new location is [tex]B'(5,0)[/tex]

Step 3: Find Equation of new line.

Points [tex]A'(0,-10)[/tex] and [tex]B'(5,0)[/tex] make a new line

The equation of given as

[tex]\frac{y-Y1}{x-X1} = \frac{Y2-Y1}{X2-X1}[/tex]

[tex]\frac{y-(-10)}{x-0} = \frac{0-(-10)}{5-0}[/tex]

[tex]\frac{y+(10)}{x} = 2[/tex]

[tex]\frac{y+(10)}{x} = 2[/tex]

[tex]y+10= 2x[/tex]

[tex]y= 2x-10[/tex]

Now, Comparing with the equation of the line : y=mx + c

Where m=slope and c is the y-intercept

We get, Slope m=2 and y-intercept c=(-10)

She planted [tex]\frac{3}{4}[/tex] arcs of each type

Step-by-step explanation:

The given is:

We need to find how many acres of each type she planted

∵ The farmer planted [tex]4\frac{1}{2}[/tex] arcs of land

∵ She planted 6 types of wheat

∵ She planted an equal amount of each type of wheat

- Divide the total number of arcs by 6 to find the number of arcs

  for each type

To divide the total number of arcs change it from the mixed number

[tex]4\frac{1}{2}[/tex] to improper fraction

∵ [tex]4\frac{1}{2}=\frac{(4*2)+1}{2}=\frac{9}{2}[/tex]

∴ The total number of arcs = [tex]\frac{9}{2}[/tex]

∴ The number of arcs of each type = [tex]\frac{9}{2}[/tex] ÷ 6

- Change the division sign to multiplication sign and reciprocal

   the number after the division sign

∴ The number of arcs of each type = [tex]\frac{9}{2}[/tex] × [tex]\frac{1}{6}[/tex]

∴ The number of arcs of each type = [tex]\frac{9*1}{2*6}[/tex]

∴ The number of arcs of each type = [tex]\frac{9}{12}[/tex]

- Reduce the fraction by dividing up and down by 3

∴ The number of arcs of each type = [tex]\frac{3}{4}[/tex]

She planted [tex]\frac{3}{4}[/tex] arcs of each type

To make a minimum profit of $100 with each snack priced at $4.00, a total of 47 snacks need to be sold at the concession stand. This includes 22 snacks to cover the total cost of $86.56 and an additional 25 snacks to achieve the profit goal.

The question is about finding out how many snacks need to be sold at a concession stand to achieve a minimum profit. To get the answer, we first need to determine how many snacks would make up the total cost, and then calculate how many additional snacks would be necessary to attain the profit goal.

Given that each snack at the concession stand costs $4.00 and that the total cost of the snacks is $86.56, we can find out how many snacks were initially purchased by dividing the total cost by the price of each snack: $86.56 ÷ $4.00 = 21.64 snacks. Since we can't sell a fraction of snack, we round up to 22 snacks to cover the total cost.

To calculate the number of additional snacks needed to attain a $100 profit, we divide the profit goal by the price of each snack: $100 ÷ $4 = 25 snacks.

Therefore, to cover the total cost and also make a minimum profit of $100, the concession stand needs to sell 22 snacks for the cost and additional 25 snacks for the profit, totaling 47 snacks altogether.

Answer:

960 cubic cm.

Step-by-step explanation:

We have to find the volume of a solid figure as detailed in the attached photo.

The topmost part of the solid is a pyramid with a square base.

The square base has a dimensions 6 cm by 6 cm and the height of the pyramid is 4 cm, then the volume is  

[tex]\frac{1}{3} \times (\textrm {Area of base} \times {\textrm {Height}}) = \frac{1}{3} \times 4 \times 6^{2} = 48[/tex] cubic cm.

Now, the volume of the bottom cuboid of the pyramid is  

= Height × Length × Width

= 12 × 6 × 6

= 432 cubic cm.

And finally, the volume of the other cuboid = 10 × 8 × 6 = 480 cubic cm.

Hence, the total volume of the solid is (48 + 432 + 480) = 960 cubic cm. (Answer)

Chloe made 4 three-point shots and 5 two-point shots.

Let's solve this problem using a system of equations.

Let x be the number of three-point shots Chloe made and y be the number of two-point shots she made.

We have the following equations:

x + y = 9 (equation 1)

3x + 2y = 22 (equation 2)

From equation 1, we can solve it for x:

x = 9 - y

Substitute this value of x into equation 2:

3(9 - y) + 2y = 22

27 - 3y + 2y = 22

-y = -5

y = 5

Substitute this value of y back into equation 1:

x + 5 = 9

x = 4

Therefore, Chloe made 4 three-point shots and 5 two-point shots.
