use Pythagorean theorem to get the missing side of the triangle as 12.

Find the area of the triangle and add ot to the area of the rectangle...so (9)(12)/2=54 for area of triangle + area of rectangle is (15)(12)=180. so 54 + 180 = 234

Answer:

5c+4p = 18.50

2c+4p = 11.20

Cost of cup = $2.4

cost of pretzels = $1.625

Step-by-step explanation:

Note:

2 cups of hot cocoa and 4 pretzels for $11.30

Computation:

5c+4p = 18.50........eq1

2c+4p = 11.30........eq2

Where c = cost of cup

p = cost of pretzels

From eq1 - eq2

3c = 7.20

c = 2.4

Cost of cup = $2.4

5c+4p = 18.50

5(2.4) + 4p = 18.50

p = 1.625

cost of pretzels = $1.625

Answer:

The weighted average for the following score is   [tex]W = 85.72[/tex]

Step-by-step explanation:

From the question we are told that

  The worth of the lab score is  23% of  total grade  i.e 0.23

   The worth of each major test is 22.5% of the total grade  0.225

   The  worth of the final  exam is  32% of the total  grade 0.32

   The  score on lab is 85  

    The score on first major test is 95

    The score on the second major test is 91

     The score on the final exam is  76

Generally the weighted average is mathematically represented as

     [tex]W  =  [0.23 *  85 ]+ [0.225 * 95] +  [0.225 * 91 ]+ [0.32 *76  ][/tex]

=>  [tex]W = 85.72[/tex]

Answer:

3 miles

Step-by-step explanation

Distance = rate x time

d=rt

rate = 9

time= 20 minutes but we need this in terms of hours since the rate is 9 miles per hour

t = 20/60 = 1/3

so d = 9(1/3) = 3 miles

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Given the following question:

[tex]2\frac{7}{8} \div3\frac{5}{6}[/tex]

To find the answer we need to convert the mixed numbers into improper fractions, then we apply KCF (Keep, Change, Flip) to the equation and then we solve.

[tex]2\frac{7}{8} \div3\frac{5}{6}[/tex]
[tex]2\frac{7}{8} =8\times2=16+7=23=\frac{23}{8}[/tex]
[tex]3\frac{5}{6} =6\times3=18+5=23=\frac{23}{6}[/tex]
[tex]\frac{28}{8} \div\frac{23}{6}[/tex]

Apply KCF:
[tex]\frac{28}{8} \div\frac{23}{6}[/tex]
[tex]\frac{28}{8} \times\frac{6}{23}[/tex]
[tex]28\times6=168[/tex]
[tex]8\times23=184[/tex]
[tex]=\frac{168}{184}[/tex]

Simplify by reducing:
[tex]\frac{168}{184}[/tex]
[tex]=\frac{168}{184}\div46=\frac{3}{4}[/tex]
[tex]=\frac{3}{4}[/tex]

Your answer is "3/4."

Answer:

a) 2/44 = 0.045

b) 9/22 = 0.409

Step-by-step explanation:

a) The probability the first can is diet soda is 3/12.

The probability the second can is diet soda is 2/11.

The probability of both is (3/12) (2/11) = 2/44 ≈ 0.045.

Alternatively, you can use combinations:

₃C₂ × ₉C₀ / (₁₂C₂) = 2/44

b) If the first can is diet soda, and the second can isn't, the probability is (3/12) (9/11) = 9/44.

If the first can isn't diet soda, and the second can is, the probability is (9/12) (3/11) = 9/44.

The total probability is 9/44 + 9/44 = 9/22 ≈ 0.409.

Alternatively, using combinations:

₃C₁ × ₉C₁ / (₁₂C₂) = 9/22

By using normal Distribution we found 15 women ran faster than Joan

The  average amount of variability in our data set is known as Standard Deviation.

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

standard deviations from the mean is used to measure Z-score

If data point's score is identical to the mean score then the z score will be zero

 Standard deviations a score X is above or below the mean measures z-score measures

From z- table we find the p values respectively.

By given , Joan’s finishing time for the Bolder Boulder 10K race was 1.83 standard deviations faster than the women’s average for her age group.

So,  Z - score = 1.83

From z - table,

If  Z =1.83 , then p-value is 0.9591.

It means that Joan was faster than 95.91% of the participants and slower than 100-95.91 = 4.09% of the participants.

Since, There were 375 women who ran in her age group.

we computed that, 4.09% faster than Joan

Number of women run faster than Joan is, = 375/100*4.09= , nearly = 15

Thus, 15 women ran faster than Joan.

Answer:

y = 3/5 + 4

Step-by-step explanation:

Given Coordiantes:

(0,4) - Y-intercept

(5,7) - Coordinates

To make an equation, first find the slope.

[tex]m=\frac{rise}{run} =\frac{y}{x}[/tex]

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

[tex]m=\frac{7-4}{5-0}[/tex]

[tex]m=\frac{3}{5}[/tex]

In decimals:

[tex]m = 0.6[/tex]

Now convert to point slope.

[tex]y-y_{1} =m(x-x_{1} )[/tex]

[tex]y-4=\frac{3}{5} (x-0)[/tex]

In decimals:

[tex]y-4=0.6(x-0)[/tex]

Now convert to slope-intercept form.

by solving for y using the Point Slope Equation.

y = 3/5 + 4

Step-by-step explanation:

I assume the boat is going straight out on the same horizontal line.

we have 2 right-angled triangles.

at point A

there is the ground distance from A to the lighthouse. which is 1390 ft.

then there is the height of the lighthouse.

and the line of sight from A to the lighthouse light.

the angle at A is 7°.

the angle at the bottom of the lighthouse is 90°.

therefore, the angle at the lighthouse light = 180 - 90 - 7 = 83°.

at point B

the ground distance from B to the lighthouse.

the height of the lighthouse again.

and the line of sight of B to the lighthouse light.

the angle at B = 4°.

the angle at the lighthouse bottom is again 90°.

therefore, the Angie at the lighthouse light is 180 - 90 - 4 = 86°.

we need the law of sine to solve this and find the missing side lengths.

a/sin(A) = b/sin(B) = c/sin(C)

with the sides and the correlated angles being opposite.

the first we need to do is finding the height of the lighthouse via triangle A, so that we can use it then also in triangle B.

1390/sin(83) = height/sin(7)

lighthouse height = 1390×sin(7)/sin(83) = 170.6705397... ft

now, we can use that in triangle B to get the ground distance to the lighthouse :

height/sin(4) = ground distance/sin(86)

ground distance = height×sin(86)/sin(4) =

= 2,440.702427... ft

the distance from A to B is the difference between that ground distance and the original distance of 1390 ft :

2,440.702427... - 1390 = 1,050.702427... ft ≈

≈ 1,051 ft
