Answer:

[tex]\boxed{\textsf{ The required answer is \textbf{130}.}}[/tex]

Step-by-step explanation:

Let us take that number be x whose 10% is 13. So According to Question 10% of x is 13. This implies ,

☯️ [tex]\underline{\underline{\boldsymbol{According\ to\ the\ Question :-}}}[/tex]

[tex]\sf\implies 10\% \ of \ x = 13 \\\\\sf\implies \dfrac{10}{100}\times x = 13 \\\\\sf\implies x =\dfrac{13\times 100}{10} \\\\\sf\implies\boxed{\pink{\frak{ x = 130 }}}[/tex]

Answer:

y + 3 = 2(x + 3)

[point-slope; y – y₁ = m(x – x₁)]

y = 2x + 3 [slope-intercept; y = mx + b]

2x – y = -3 [standard form; ax + by = c]

Answer:

Step-by-step explanation:

2x+3y= 6     ========================>>>           2x +  3y = 6

x+y=4    =====   times both sides by 2  =====>>>    2x + 2y = 8

             ==== subtract these two equations ==>>  (2x - 2x) + (3y - 2y) = 6 - 8

                                                                                       0x     +      y       =   -2

        y = -2     so if  x + y = 4             plug in -2 where y was

                             x + (-2) = 4              add 2 to both sides

                                    x   =  6

(6,-2)

(-2,6)

(-3, 4)

Answer:

2667

Step-by-step explanation:

35 meters wide at the base

20.6 meters tall

h = 20.6 m

slant height s = 27.029798371427 m

side length a = 35 m

lateral edge length e = 32.200310557509 m

1/2 side length r = 17.5 m

volume V = 8411.6666666667 m3

lateral surface area L = 1892.0858859999 m2

base surface area B = 1225 m2

total surface area A = 3117.0858859999 m2

Answer:

the area is 324 cm²

Step-by-step explanation:

Answer:

area = 324 cm²

Step-by-step explanation:

since it's  a square, all sides are equal in length.

72/4 = 18

18 x 18 = 324 cm²

Answer:

For a cylinder there is 2 kinds of formulas the lateral and the total. the lateral surface area is just the sides the formula for that is 2(pi)radius(height). the formula for the total surface area is 2(pi)radius(height) + 2(pi)radius squared.

Answer:

Step-by-step explanation:

Answer:

0.25

Step-by-step explanation:

write 1/4 as a decimal you have to divide numerator by the denominator of the fraction. We divide now 1 by 4 what we write down as 1/4 and we get 0.25. And finally we have: 1/4 as a decimal equals 0.25.

Answer:

0.25

Step-by-step explanation:

[tex] \frac{1}{4} \\ = 0.2[/tex]

The coordinates of point B are located at -5 on the number line, and Point A is located at -8 on the number line. The reflection of point A on the number line is the coordinates of point E.

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.

According to the given number line,

The coordinates of point B are located at -5 on the number line, and Point A is located at -8 on the number line. The reflection of point A on the number line is the coordinates of point E.

Thus, Point B is at -5 on the number line, whereas Point A is at -8 on the number line. Point E is the number line's reflection of point A.

Answer:

7 hours

Step-by-step explanation:

the function of the earning of Zoe = 2.50 + 1.75h

2.5 = base fixed amount

1.75 varies based on the hours

h = hours

2.50 + 1.75h = 14.75

to solve for h

subtract 2.5 from both sides and then divide by 1.75

14.75 - 2.5 = 1.75h

12.25 = 1.75h

h = 7

Answer:

[tex]x = 77 - 2y[/tex]

[tex]y = \frac{77 - x}{2}[/tex]

Step-by-step explanation:

Given

[tex]2x + 4y - 31 = 123[/tex]

Required

Solve for x and for y

[tex]2x + 4y - 31 = 123[/tex]

Add 31 to both sides

[tex]2x + 4y - 31+31 = 123+31[/tex]

[tex]2x + 4y = 154[/tex]

Solving for x

Subtract 4y from both sides

[tex]2x + 4y - 4y = 154 - 4y[/tex]

[tex]2x = 154 - 4y[/tex]

Divide by 2

[tex]x = 77 - 2y[/tex]

Solving for y

[tex]2x + 4y = 154[/tex]

Subtract 2x from both sides

[tex]2x - 2x + 4y = 154 - 2x[/tex]

[tex]4y = 154 - 2x[/tex]

Divide by 4

[tex]y = \frac{154 - 2x}{4}[/tex]

Split

[tex]y = \frac{77 - x}{2}[/tex]

Answer:

x = 3

Step-by-step explanation:

-24 < x - 3 - 8x

-24 < -7x - 3

-24 + 3 = -21

-7x - 3 + 3 = -7x

-21 = -7x

-21 / -7 = 3

-7x / -7 = x

3 = x
