Answer:

Step-by-step explanation:

[tex]Florence \ washed \ 3\ cars \ and\ earned\ = \$ x\\\\[/tex]

[tex]Cost\ of \ washing \ one \ car = \frac{x}{3}[/tex]

[tex]Anona \ washed \ 5 \ cars \ and \ earned \ 16 \ more \ than \ Florence = x + 16[/tex]

[tex]Cost\ of \ washing \ one \ car \ by \ Anona = \frac{x +16}{5}[/tex]

 [tex]\frac{x}{3} = \frac{x + 16}{5}\\[/tex]                    [tex][ \ cross \ multiply \ ][/tex]

[tex]5 \times x = 3 \times( x + 16)\\\\5x = 3x + 48\\\\5x - 3x = 48\\\\2x = 48\\\\x = 24[/tex]

[tex]Cost \ of \ washing \ one \car = \frac{x}{3} = \frac{24}{3} = \$ 8[/tex]

Therefore ,

                 Florence earned $24

                 Anona earned 24 + 16 = $40  

                 Caragh Washed 4 cars, so Caragh earned = 8 x 4 = $32

In the diagram below, ΔABC ≅ ΔDEF. Therefore, by CPCT, ∠B = ∠E.

Corresponding parts of congruent triangles or CPCT is used to denote the relation between the sides and the angles of two congruent triangles.

Since, ΔABC ≅ ΔDEF,

AB = DE

BC = EF

AC = DF

∠A = ∠D

∠B = ∠E

∠C = ∠F

Answer:

140 trees

Step-by-step explanation:

Number of trees planted on one side of the road = length of the road / intervals

1000m = 1km

0.28 x 1000 = 280m

280 / 4 = 70

number of trees planted on both sides of the roads = 70 x 2 = 140 trees

[tex] \large \boxed{ {a}^{2} + {b}^{2} = {(a + b)}^{2} - 2ab}[/tex]

The formula is derived from the (a+b)² which can be expanded as:

[tex] \large \boxed{ {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} }[/tex]

Now since we only want a²+b² and not 2ab. We can add -2ab after (a+b)² which result in (a+b)²-2ab. This formula is pretty useful it comes to higher maths.

Answer:

The rate of interest is 12 %.

Step-by-step explanation:

The yearly compound interest on sum of money in one and two years are RS 1800 and RS 3816 respectively.

[tex]1800 = P\left ( 1+\frac{r}{100} \right )- P.... (1)\\\\3816 = P\left ( 1+\frac{r}{100} \right )^2- P.... (2)\\\\Divide (2) by (1)\\\\\frac{3816}{1800}=\frac{\left ( 1+\frac{r}{100} \right )^2-1}{\left ( 1+\frac{r}{100} \right )-1}\\\\38.16 r = 1800 (1 +0.0001 r^2 + 0.02r -1)\\\\r = 0.12 =12 percent[/tex]

Answer:

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

4^2 + y^2 = 21^2

16 + y^2 = 441

y^2 = 441 - 16

y^2 = 425

[tex]y = \sqrt{425}[/tex]

[tex]y = 5\sqrt{17}[/tex]

y = 13.2

a^2 + b^2 = c^2

4^2 + x^2 = 7^2

16 + x^2 = 49

x^2 = 40 - 16

x^2 = 33

x = [tex]\sqrt{33}[/tex]

x = 5.7 m

Answer:

9 and 10

Step-by-step explanation:

To work this out, you can either evaluate [tex]\sqrt{89}[/tex] or find the 2 closest perfect squares to 89.

With the second method, the 2 closest perfect squares are 81 and 100, otherwise known as 9² and 10². This means [tex]\sqrt{81}[/tex] is between 9 and 10.

With the first method, the result is 9.4339811320... which is between 9 and 10.

Answer:

x=5

Step-by-step explanation:

7x - 4y = 23 and x + y = 8

Multiply the second equation by 4

4x + 4y = 32

Add this to the first equation

7x - 4y = 23

4x + 4y = 32

Answer:

y=2

Step-by-step explanation:

3 = (y+7)/3

Multiply each side by 3

3*3 = (y+7)/3 *3

3*3 = y+7

9 = y+7

Subtract 7 from each side

9-7 = y+7-7

2 =y

Answer:

2 = y

Step-by-step explanation:

3 = y + 7 ÷ 3

multiply both side of equation by 3

3 × 3 = y + 7 ÷ 3 / 3

9 = y + 7

subtract 7 from both side

9 - 7 = y + 7 - 7

2 = y

Answer:

The answer is Yes .. Ron is correct

Step-by-step explanation:

This is because each side of the outer square is 2 units summing up to 8 units. So dividing each into two equal parts give 1 unit each.

Each side of the inner square divides the outer square into two making each side 1 unit.

The inner square thus takes 1 unit for it's side summing the perimeter to 4 units.

log 27 a la base 3 = 3 (In spanish)

log 27 to the base 3 = 3

Answer:

0.17

Step-by-step explanation:

41×cos(D) = 9

cos(D) = 9/41

=>

in a circle with the radius of 41 the point on the circumference of the circle for the angle D has an x-distance from the center of the circle of 9.

therefore, cos(D) = that x-distance divided by the radius (as the trigonometric functions only deliver the values for the norm circle with radius 1).

what is the y-distance (sin(D)×41) ?

r² = x² + y²

41² = 9² + y²

1681 = 81 + y²

1600 = y²

y = 40

therefore, sin(D) = 40/41

tan(D) = sin(D)/cos(D)

you know how to divide 2 fractions with each other ?

by multiplying the 2 outer factors (to top-most and bottom-most) as the top part of the result, and by multiplying the 2 inner factors for the bottom part of the result.

(40/41 - 9/41) / (40/41 / 9/41) =

= 31/41 / (40×41 / 9×41) = 9×41×31 / 40×41×41 =

= 9×31 / 40×41 = 279 / 1640 ≈ 0.17
