Step-by-step explanation:

Area of composite shapes:

13) Figure 1:

         Figure1 is a rectangle.

         l = 4 cm & w = 2 cm

Area of figure1 = l * w

                         = 4 * 2

                         = 8 cm²

 Figure2:

              Figure2 is a parallelogram

               base = b = 4 cm

                  h = 4 cm

   Area of figure2 = b * h

                             = 4 * 4

                            = 16 cm²

Area of composite shape = 8 + 16

                                          = 24 cm²

14) Figure1:

       Figure 1 is a trapezium. a & b are parallel sides and h is the height

       a = 4 cm ; b = 6 cm; h = 4 -2 = 2 cm

[tex]\sf Area \ of \ figure1 =\dfrac{(a+b)*h}{2}[/tex]

                        [tex]= \dfrac{(4 +6)*2}{2}\\\\= 10 \ cm^{2}[/tex]

Figure2:

   Figure2 is rectangle. l = 6 cm ; w = 2 cm

  Area of figure2 = 6*2

                             = 12 cm²

Area of composite shape = 10 + 12

                                          = 22 cm²

15) Figure 1 & figure 2:

           Figure 1 and  figure 2 are congruent triangles

             base = b = 3 cm & h= 4 cm

[tex]\sf area \ of \ figure1 \ and \ figure 2 = 2*\dfrac{1}{2}b*h[/tex]

                                        = b *h

                                         = 3 * 4

                                        = 12 cm²

Figure3:

    Figure 3 is a square.

      side =  3 cm

  Area of figure3 = side *side

                             = 3 * 3

                            = 9 cm²

Area of composite shape = 12 + 9

                                          = 21 cm²

Answer:

Step-by-step explanation:

This is a horrible credit union  they charged $3, just for her to have access to her own money, then they overdraft fee charged  her for $20  :/   she spent 62 dollars , that she had, but b/c they charged her 3 dollars to access her money,  it made her also get the overdraft fees.  This seems like usery to me and this bank should be closed.  Fined ,  and barred from doing business.  >:/  

so on the 11th she was -23  dollars,  she was in debt to her bank 23 dollars,  

88-23=65

on the 16th she was 65-43 = 22    postive :)

Answer:

500^1/3

Step-by-step explanation:

Since it is a cube root, the exponent is 1/3.

Answer:

[tex]8\frac{2}{6}\\\\2\frac{1}{5}[/tex]

Fractions are sometimes the same as dividing, for this case, that rule applies.

[tex]\frac{50}{6}\\\\\frac{11}{5}[/tex]

↑ These improper fractions translate to...

[tex]\frac{50}{6} = 8\frac{1}{3} -- > 8\frac{2}{6} \\\\ \frac{11}{5} = 2\frac{1}{5}[/tex]

Answer:

1)  D. 8 2/6 hotdogs

2)  B. 2 1/5 cakes

Step-by-step explanation:

1) If she's dividing 50 hotdogs equally among 6 people, then you would divide 50 by 6 to find how many each person gets.
note: 50 ÷ 6 is the same as [tex]\frac{50}{6}[/tex].

[tex]\frac{50}{6}[/tex] =  [tex]8\frac{2}{6}[/tex]

6 can go into fifty 8 times, so there is a whole number of 8. There is 2/6 left over, so the final result is [tex]8\frac{2}{6}[/tex].

2) If Sako makes 11 cakes and wants to share it equally among 5 people, we can divide 11 by 5 to find how many each person gets.

[tex]\frac{11}{5} =2\frac{1}{5}[/tex]

5 can go into eleven 2 times, so there is a whole number of 2. There is 1/5 leftover, so the final result is [tex]2\frac{1}{5}[/tex].

Hence, the answers are D, and B.

Answer:

2147483648

Step-by-step explanation:

The pattern being used is x4.

8 x 4 = 32

32 x 4 = 128

128 x 4 = 512

512 x 4 = 2048

2048 x 4 = 8192

8192 x 4 = 32768

32768 x 4 = 131072

131072 x 4 = 524288

524288 x 4 = 2097152

2097152 x 4 = 8388608

8388608 x 4 = 33554432

33554432 x 4 = 134217728

134217728 x 4 = 536870912

536870912 x 4 = 2147483648

Answer:

Mean would be 84, Mode would be 89, Range would be 19.

Step-by-step explanation:

Mean- 89 +78 + 91 + 90 + 89 + 97= 534

534 divided by 6= 89

Mode- There are 2 89's so thats your mode. Mode is your most frequent number.

Range- 97-78=19. For range you have to subtract your highest number by your lowest.

Answer:

measurement precision

Step-by-step explanation:

The consistency of repeated measurement, often expressed by the number of decimal places, is called a measurement's precision.

Answer:

Step-by-step explanation:

Remark

You have to convert one of the numbers. It doesn't matter which one, but you can't simply divide one into the other the way the numbers stand.

Conversion

20 kilograms = 20 * 1000 grams / kg

20 kilograms = 20000 grams

Formula

Number of books = mass of bookcase / mass of 1 book

Givens

number of books = ??

mass of bookcase = 20000 grams

mass of one book = 500 grams

Solution

number of books = 20000 / 500

number of books = 40

Answer: 40 books =  mass of bookcase

Answer:

56 questions.

Step-by-step explanation:

percent got wrong = 100% - percent got correct.

percent got correct = 72%

percent got wrong = 100%-72% = 28% or 0.28

questions got wrong = total questions * percent got wrong.

total questions = 200

questions got wrong = 200*0.28 = 56 questions

Therefore, Sophie got 56 questions wrong.

Answer:

SQR = 118

RQT = 62

Step-by-step explanation:

SQR + RQT = 180

10x - 22 + 3x + 20 = 180

13x - 2 = 180

13x = 182

x = 14

Answer:

m∠RQT=62°

m∠SQR=118°

Step-by-step explanation:

m∠SQT=m∠SQR+m∠RQT

180°=(10x-22°)+3x+20°

180°=13x-2°

180°+2°=13x

182°=13x

x=182÷13=14°

x=14°

So,

m∠RQT=3(14)+20°=62°

And,

m∠SQR=10(14)-22°=140°-22°

m∠SQR=118°

Answer:

Los ángulos coterminales son ángulos que tienen como lado inicial el eje x y tienen el lado terminal común.

Por ejemplo un ángulo de 20º tendría un ángulo cotermiunal en 360º+20º=380º ó en 360º×2+20º= 720º+20º=740º.

a)2560º÷360º =7 ⇒  7×360º+40º, luego 40º será su ángulo coterminal entre 0º y 360º

b) 3.600º÷360º= 10 ⇒ 10×360º+0, luego 0º será su ángulo coterminal entre 0º y 360º

c) 1.090º÷360º= 3 ⇒ 3×360º+10º, luego 10º será su ángulo coterminal entre 0º y 360º

Step-by-step explanation:

Primero lo que necesitas saber es que los ángulos coterminales son ángulos que tienen como lado inicial el eje x y tienen el lado terminal común.

Por ejemplo: un ángulo de 20º tendría un ángulo coterminal en 360º+20º=380º ó en 360º×2+20º= 720º+20º=740º.

Apartir de lo anterior, aplicamos lo siguiente:

2560º÷360º =7 ⇒  7×360º+ 40º,

Respuesta: 40º será su ángulo coterminal entre 0º y 360º.

The correct choice of this question with the given polynomial is "The zeros are -2 and 8, because the factors of g are (x + 2) and (x - 8)". (Correct choice: H)

In this case we have a second order polynomial of the form x² - (r₁ + r₂) · x + r₁ · r₂, whose solution is (x - r₁) · (x - r₂) and where r₁ and r₂ are the roots of the polynomial, which can be real or complex numbers but never both according the fundamental theorem of algebra.

If we know that g(x) = x² - 6 · x - 16, then the factored form of the expression is g(x) = (x - 8) · (x + 2). Hence, the correct choice of this question with the given polynomial is "The zeros are -2 and 8, because the factors of g are (x + 2) and (x - 8)". [tex]\blacksquare[/tex]

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;

5 x 4 = 20

If a color is selected at random the probability would be

[tex]\frac{part}{whole}[/tex]

our part is 5

our whole is 20

so the probability would be;

[tex]\frac{5}{20}[/tex] or [tex]\frac{1}{4}[/tex] when reduced

Answer:

$28

Step-by-step explanation:

Given:

data = [22,30,35,25,25,20,27]

For eight night, the new list is:

new_data = [22,30,35,25,25,20,27,x]

Mean = 26.50

Mean Formula:

[tex]\displaystyle \large{m=\dfrac{x_1+x_2+x_3+...+x_n}{n} }[/tex]

Therefore:

[tex]\displaystyle \large{26.50=\dfrac{22+30+35+25+25+20+27+x}{8}}[/tex]

Multiply both sides by 8:

[tex]\displaystyle \large{26.50\cdot 8=\dfrac{22+30+35+25+25+20+27+x}{8} \cdot 8}\\\displaystyle \large{212=22+30+35+25+25+20+27+x}[/tex]

Solve for x:

[tex]\displaystyle \large{212=22+30+35+25+25+20+27+x}\\\displaystyle \large{212=184+x}[/tex]

Subtract 184 both sides:

[tex]\displaystyle \large{212-184=184+x-184}\\\displaystyle \large{28=x}[/tex]

Therefore, she will earn $28 in eighth night

The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.

Answer: $28.

Step-by-step explanation: To solve this problem, we should first find the mean of the data with the seven payments that are given already:

22 + 30 + 35 + 25 + 25 + 20 + 27 = 184.

184 / 7 = 26.2857142857.

In order to figure out how much she made the eighth night with the mean of the data being $26.50, we can pick a number and add it to 184 (the total of the seven payments), and divide the total by 8.  The number we can try is 28. The work is done below:

184 + 28 = 212.

212 / 8 = $26.50.

Therefore, Laura's payment on the eighth night was $28.
