From an electronic shop, 34 washing machines were sold on a particular day. The price of one washing machine was 8,400. Find the total amount collected by selling the washing machines on that day

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°

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:

$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.

Answer: 15 guests.

Step-by-step explanation:

As the statement says that Carly has 9 1/2 of ice cream and each guest will be served 3/5 pint of ice cream, to determine the number of guests that she can serve, you have to divide 9 1/2 by 3/5:9 1/2÷3/5. 19/2÷3/5=95/6= 15According to this, the greatest number of guests that Carly can serve is 15 guests.

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.

To find GCF we need to find what these expressions have in common

30x²=5*3*2x²

45x⁵=5*3*3x²x³

Now we can see, that GCF=5*3*x² = 15x²

Answer :

15x²

Answer: A

Step-by-step explanation:

Using compound interest and continuous compounding, it is found that Lincoln would have $15,856 more in his account than Eli.

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

Hence, for Lincoln, we have that the parameters are as follows:

P = 49000, r = 0.06125, n = 365, t = 20.

Hence the amount will be of:

[tex]A_L(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]A_L(20) = 49000\left(1 + \frac{0.06125}{365}\right)^{365 \times 20}[/tex]

[tex]A_L(20) = 166787[/tex]

The amount is given by:

[tex]A(t) = Pe^{rt}[/tex]

For Eli, we have that r = 0.05625, hence the amount will be given by:

[tex]A(t) = Pe^{rt}[/tex]

[tex]A_E(20) = 49000e^{0.05625 \times 20} = 150931[/tex]

It is given by:

[tex]D = A_L(20) - A_E(20) = 166787 - 150931 = 15856[/tex]

Lincoln would have $15,856 more in his account than Eli.

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:

All squares must be rectangles.

Step-by-step explanation:

This quadrilateral is known as a square. A square is a closed figure with four sides of equal lengths and four right angles. By definition, a rectangle is a closed figure with four straight sides and four right angles. So comparing both of these definitions, a square must be a rectangle. Rectangles sides are not all equal. This about about the only difference.

-5 is the solution to the inequality x < -4 and the interval is the x ∈ (-∞, -4) option first is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have inequality:

x < -4

The solutions to the above inequality will lie in the region (-∞, -4)

x ∈ (-∞, -4)

From the number line, we can mark the region for the above interval (refer attached picture)

Thus, -5 is the solution to the inequality x < -4 and the interval is the x ∈ (-∞, -4) option first is correct.

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
