Answer:

26ft

Step-by-step explanation:

Complete Question:

The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet. Find its length

Formula for calculating the area of a rectangle is expressed as shown;

Area of a rectangle = Length * Width

Given the equation a = 26w that gives the area of a rectangle

On comparing with the formula;

Length * Width = 26w

Length = 26ft (by comparison)

Hence the length of the rectangle is 26ft

Answer: 5(2x+13)

Step-by-step explanation: Hope this was helpful....

The value of the measure of angle B will be;

⇒ ∠ B = 87.13°

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The value is,

⇒ cos B = 0.05

Now,

Since, The value is,

⇒ cos B = 0.05

Taking cos inverse both side, we get;

⇒ cos⁻¹ cos B = cos⁻¹ 0.05

⇒ B = 87.13°

Thus, The value of angle B = 87.13°

Answer:

747+9+83=839

Step-by-step explanation:

We can use 9x83=747 as a extra help to get the answer. Say you need the answer above (which I gave you) so you get 9x83 as an example to help figure out 749+9+83=839.

Pythagorean Theorm Unit? I got you!

It would be C, about 63.07

Answer:

31.4

Step-by-step explanation:

Circumference = 2 × pi × r

C = 2 × 22/7 × 5

C = 220/7

C = 31.4

Answer:

£3.25

Step-by-step explanation:

£9.25×2+ £9.50+£10.55+£4×4.55

18.5+9.50+10.55+18.2

=£3.25

Answer:

£2.75

Step-by-step explanation:

2(9.25) + 1(9.50) + 1(10.55) + 4(4.55) = x

19.00 + 9.50 + 10.55 + 18.20 = x

28.50 + 28.75 = x

57.25

60 - 57.25 = 2.75

Answer: False. When multiplying or dividing by an negative inequality you flip the sign.

Answer:

11

Step-by-step explanation:

x= -b/2a

x= -8/2(-2)

x=-4/-2

x=2

f(2) = -2(2) +8(2)+ 3

f(2) = -8 +16 + 3

f(2) = 11

Maximum value is 11

Answer:

11

Step-by-step explanation:

it has a vertex at (2,11)

.

f(2) = 11

how to find the vertex;

function equation is f(x) = ax^2 + bx + c

we can find x by :-b/2a, -8/-4 = 2

and by putting the x value we get the y

f(2) = 11

Answer:

2/3

Step-by-step explanation:

10/15 = 2/3

15/24 = 2/3

Answer:

The lines are perpendicular.

Step-by-step explanation:

If the lines are parallel, then the slopes are equal

If the lines are perpendicular, then the slopes are negative reciprocals

If neither of the above occur, then the lines are neither parallel or perpendicular.

y = 2x + 3  is in slope-intercept form, so the slope = 2

2y + x = 6

Solve for y:    2y = -x + 6

                        y = -1/2(x) + 3    so the slope = -1/2

2 and -1/2 are negative reciprocals, so the lines are perpendicular.

Note:  Negative reciprocals have a product of -1.  2(-1/2) = -1

Answer:

a = 127°

Step-by-step explanation:

The 3 angles lie on a straight line and have a sum of 180°, that is

15° + a + 38° = 180°

53° + a = 180° ( subtract 53° from both sides )

a = 127°

Step-by-step explanation:

A garden is in a shape of an equilateral triangle with side 4 ft.

The objective is to find the area of the garden.

The formula to find the area of the triangle is, A= 1/2• b • h

Here, b represents the side of the triangle and h represents and h represents the height of the triangle.

The height of an equilateral triangle can be calculated by,

H = /3/2 • b

= /3/2 • 4

=

[tex] \sqrt[2]{3} [/tex]

Now substitute the value of b and h in the formula of area of triangle.

A = 1/2 • 4 •

[tex] \sqrt[2]{3} [/tex]

=

[tex] \sqrt[4]{3} [/tex]

Area is:

Answer:

1/3(x-1)

Step-by-step explanation:

1/3x - 1/3

Both terms have a greatest common factor of 1/3

1/3 *x - 1/3 *1

Factor out a 1/3

1/3(x-1)

Answer:

the length is 33 feet

Step-by-step explanation:

The computation of the length is shown below:

Let us assume the length be x

So the width be 1 by 3 x

And the area is 363 square feet

So

As we know that

Area = length × width

363 = x × 1 ÷ 3 x

363 = 1 ÷ 3x^2

Now

363 × 3 = x^2

1089 = x^2

x = 33 feet

hence, the length is 33 feet

Answer: 1 solution I think

Step-by-step explanation:

Answer:

$13

Step-by-step explanation:

Given that :

Increase in salary factor = 11/10

New salary = $14.30

Initial salary = x

To obtain the value of the initial salary,

The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary

11 / 10 * x = 14.30

1.1x = 14.30

x = 14.30 / 1.1

x = $13

Hence.initial salary per hour = $13
