[tex]99\ inches[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\Diameter\ of\ the\ Sun\ or\ the\ Semi-Circular\ Window=63\ inches\\Hence\ in\ order\ to\ find\ the\ length\ of\ the\ top\ part,\ we\ need\ to\\ find\ the\ semi-circumference\ of\ the\ window.\\Hence,\\As\ we\ know\ that,\ in\ any\ circular\ figure,\\Radius=\frac{Diameter}{2} \\Hence\ here,\\Radius\ of\ the\ Semi-Circular\ Window=\frac{63}{2}\\Hence,\\As\ the\ Circumference\ of\ a\ circle= 2\pi r[/tex][tex]Hence,\\Semi-Circumference= \frac{Circumference}{2}\\Hence,\\ Semi-Circumference=\frac{2\pi r}{2}\\Semi-Circumference=\pi r\\Hence\ taking\ r=\frac{63}{2}\ and\ \pi =\frac{22}{7} ,\\The\ Semi-Circumference\ of\ the\ Semi-Circular\ Window=\pi *\frac{63}{2} \\The\ Semi-Circumference\ of\ the\ Semi-Circular\ Window= \frac{22}{7}*\frac{63}{2}\\[/tex]

Step-by-step explanation:

Since the total is $5,876 you want to divide by the number of people 26 to equally split the money.

$5,876/26=226

Answer:

The value is [tex]P( O \ and \ A ) = 0.583[/tex]

Step-by-step explanation:

From the question we are told that

   The  number of apples is  [tex]A = 7[/tex]

   The  number of oranges is  [tex]R = 5[/tex]

Generally the probability that the bowl will be empty after the last apple  is taken from the box is mathematically represented as

  The probability that  5 oranges   and 7 apples are drawn in the 1st 11 draws

So

      [tex]P( O \ and \ A ) = \frac{(^5 C_5) * (^7 C_6) }{^{12} C_{11}}[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

      [tex]P( O \ and \ A ) = \frac{(1 * 7 )}{12}[/tex]

=> [tex]P( O \ and \ A ) = 0.583[/tex]

Answer:

x=48 degrees

y=66 degrees

Step-by-step explanation:

180-114=66 degrees

y=66 degrees

180- (66+66)

180-132

48 degrees

x= 48 degrees

Answer:

1.66 (appx)

Step-by-step explanation:

According to BODMAS rule , we should solve division operation in the expression first , then we'll finish the addition opearation .

[tex]0.65 \div 0.75 + 0.8[/tex]

[tex] = > \frac{65}{100} \div \frac{75}{100} + \frac{8}{10} [/tex]

[tex] = > \frac{65}{100} \times \frac{100}{75} + \frac{8}{10} [/tex]

[tex] = > \frac{13}{15} + \frac{8}{10} [/tex]

[tex] = > \frac{(13 \times2) + (8 \times 3) }{30} [/tex]

[tex] = > \frac{50}{30} = \frac{5}{3} = 1.6666.........[/tex]

Answer: 344.7

Explanation:

344.7∣234

  (Cut ^off point at the line)

The digit to the right of the cut of the point is less than 5. So the digit to its left (the 7) is not changed and all those to the right are changed to 0 gives you:

344.7000

Written as 344.7

Hope this helps and hope you have a wonderful day :)

Answer:

Option D

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph attached,

Since, the given line passes through two points (-3, 0) and (0, 2),

Slope of the line = [tex]\frac{2-0}{0-(-3)}[/tex]

                           = [tex]\frac{2}{3}[/tex]

y-intercept of the line is the point of intersection of the line and y-axis.

Therefore, y-intercept of the line given in the graph is,

y = 2 units

Option D is the answer.                    

Answer:

x = 44.4°

Step-by-step explanation:

Use SOHCAHTOA.

In this case, use sine trigonometric function formula

[tex] \sin(x) = \frac{o}{h} [/tex]

The opposite side of angle is 7.

The hypoteneuse is 10.

So,

[tex] \sin(x) = \frac{7}{10} \\ x = \sin ^{ - 1} ( \frac{7}{10} ) \\ x = {44.427}^{o} \\ x = {44.4}^{o} [/tex]

9514 1404 393

Answer:

  44.4°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Sin = Opposite/Hypotenuse

  sin(x) = 7/10

  x = arcsin(7/10)

  x = 44.4°

Answer:

  RB = 16

Step-by-step explanation:

When chords cross, the product of the lengths of the pieces of the chord is the same for all:

  RB·RD = RE·RC

  RB = RE·RC/RD = 8·14/7 = 8·2

  RB = 16

Answer:

95.5°F

Step-by-step explanation:

Given the regression equation :

y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold

y = number of ice cream sold

x = temperature (°F)

The temperature when 95 iccream cones are sold will be ;

Here, y = 95

Using the model :

95 = 1.8x - 76.9

95 + 76.9 = 1.8x

171.9 = 1.8x

Divide both sides by 1.8

171.9 / 1.8 = x

95.5°F = x

Hence, temperature when 95 cones of ice-cream are sold is 95.5°F

Answer:

Step-by-step explanation:

Emery is paid 15 dollars an hour and she worked 38 hours

15*38=570 dollars just from the hourly wage

the commission is 2.25% and her sales were 3,200 dollars

(3200*2.25)/100=72

total=570+72=642

Step-by-step explanation:

Given that,

No. of chocolate chip cookies = 86

No. of sugar cookies = 42

We need to find the number of identical packages that I can make.

It means we need to find the HCF of these 2 number.

Prime factorization of 86 and 42 as follows :

86 = 2 x 43

42 = 2 x 3 x 7

HCF = 2

Hence, I can make 2 identical packages.

Answer:

Assuming there can only be 2 cookies per identical package, She can make 42 identical packages which contains 2 chocolate chip cookies and 1 sugar cookie.

86 / 2 = 43 chocolate chips cookies

42 / 1 = 42 sugar cookies

With the sugar cookies not having the capability to match the requirements we will assume for this answer that an "Identical Package" is composed of 2 chocolate chip cookies, and a single sugar cookie.

Answer:

[tex]y+5 = \frac{1}{15}(x - 3)}[/tex]

Step-by-step explanation:

Given

[tex]m = \frac{1}{15}[/tex] -- Slope

[tex](x_1,y_1) = (3,-5)[/tex] --- Point

Required

Write an equation in point slope form

The point slope form of an equation is:

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for y1, x1 and m

[tex]y-(-5) = \frac{1}{15}(x - 3)}[/tex]

[tex]y+5 = \frac{1}{15}(x - 3)}[/tex]

Hence, the equation in point slope form is:

[tex]y+5 = \frac{1}{15}(x - 3)}[/tex]

Answer:

$1.87

Step-by-step explanation:

Since the total cost was $18.70 and there are ten in the pack, to find the price of one notebook you just need to divide the total cost by the amount of notebooks there are. So 18.70 divided by 10 is $1.87 for each notebook.

Answer:

[tex]Perimeter = 34cm[/tex]

Step-by-step explanation:

Given

Represent the adjacent sides with A and B

[tex]A= 7cm[/tex]

[tex]B = 10cm[/tex]

Required

Determine the perimeter

The perimeter is calculated as follows;

[tex]Perimeter = 2 * (L + B)[/tex]

[tex]Perimeter = 2 * (7cm + 10cm)[/tex]

[tex]Perimeter = 2 * (17cm)[/tex]

[tex]Perimeter = 2 * 17cm[/tex]

[tex]Perimeter = 34cm[/tex]
