What is the product of (2x-1) (x+5)?

Answer:

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

Step-by-step explanation:

The diagonal divides the square into 2 right angles with legs s and hypotenuse x

Using Pythagoras' identity on one of the right triangles, then

s² + s² = x²

2s² = x² ( divide both sides by 2 )

s² = [tex]\frac{x^2}{2}[/tex] ( take the square root of both sides )

s = [tex]\sqrt{\frac{x^2}{2} }[/tex] = [tex]\frac{x}{\sqrt{2} }[/tex]

Thus

perimeter = 4s = 4 × [tex]\frac{x}{\sqrt{2} }[/tex] = [tex]\frac{4x}{\sqrt{2} }[/tex]

Multiply numerator/ denominator by [tex]\sqrt{2}[/tex]

perimeter = [tex]\frac{4x\sqrt{2} }{2}[/tex] = 2[tex]\sqrt{2}[/tex] x

Answer: oop ;-;

Step-by-step explanation: We have two basic equations

A = B + 826         A is 826ft taller than B

A + B = 1516       Combined height is 1516 ft

Replace A with B+826 in 2nd equation and solve for B

B + 826 + B = 1516    Combine like terms

2B + 826 = 1516         Subtract 826 from both sides

2B = 690                    Divide both sides by 2

B = 690/2

B = 345 ft

We know that A = B + 826 so you simply need to do

that addition to have the height of both towers.

Answer:

She is incorrect.

Step-by-step explanation:

She is incorrect.

An integer is a whole number, zero, and the opposites of the whole numbers. There cannot be a decimal part or fractional part to an integer.

Here are the integers:

..., -3, -2, -1, 0, 1, 2, 3, ...

-5.5 is not an integer.

Rachel's statement that -5.5 is an integer because it is negative is not correct because -5.5 is a rational number.

Given,

Rachel states that -5.5 is an integer because it is negative.

We need to find out whether Rachel's statement is correct and give a reason.

Integers are 0,±1, ±2, ±3, ±4, ±5, ±6, ±7, ±8,......

It includes all whole numbers.

We have,

-5.5 is a negative rational number.

Integer has no decimal point.

-5.5 is not an integer.

Thus Rachel's statement that -5.5 is an integer because it is negative is not correct.

Answer:

Deshaun =  $590 - $35x

Isabel :  $790 - $55x

$590 - $35x = $790 - $55x

Step-by-step explanation:

For  Deshaun :

Amount in her account = $590

Amount she would have withdrawn by month x = $35 × x = $35x

The amount she would have in her account = $590 - $35x

For Isabel :

Amount in her account = $790

Amount she would have withdrawn by month x = $55 × x = $55x

The amount she would have in her account = $790 - $55x

Let x be the time when the money in their account would be equal  =

$590 - $35x = $790 - $55x

Answer:

Number of sugar cubes  fit in box = 600 sugar cube

Step-by-step explanation:

Given:

Size of sugar cube = 1 x 1 x 1 cm

Size of box.

Length = 5 cm

Width = 12 cm

Height = 10

Find:

Number of sugar cubes  fit in box

Computation:

Volume of sugar cube = 1 x 1 x 1

Volume of sugar cube = 1 cm³

Volume of box  = 5 x 10 x 12

Volume of box  = 600 cm³

Number of sugar cubes  fit in box = Volume of box / Volume of sugar cube

Number of sugar cubes  fit in box = 600 / 1

Number of sugar cubes  fit in box = 600 sugar cube

Answer:

600

Step-by-step explanation:

volume of the cube a^3 = 1×1×1  = 1 cm^3

Volume of the box = 5×10×12 =600 cm^3

No. of the sugar cubes fit in the box = Volume of the box/ vol. of the cube

Answer:

8 units

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi*r

50.24 = 2 * pi * r

Using 3.14 to approximate pi

50.24 = 2 * 3.14 * r

50.24 = 6.28 r

Divide each side by 6.28

50.24/6.28 = r

Answer:

The four angles are;

30 degrees,  85 degrees, 95 degrees , and 150 degrees

Step-by-step explanation:

Call the four angles of this quadrilateral A, B, C, and X (being X the smallest angle)

Then angle A is 55 degrees larger than X , therefore we can write it as X+55

Angle B is 65 degrees larger than X , therefore we can write it as X+65

Angle C is 120 degrees larger than X , therefore we can write it as X+120

Then we know that the addition of all four angles of a quadrilateral must give 360 degrees , so we have:

X + X + 55 +X + 65 + X + 120 = 360

that is:

4 X + 240 = 360

4 X = 360 -240

4 X = 120

X = 120/4

X = 30 degrees

and the other angles are:

30 + 55 = 85 degrees

30 + 65 = 95 degrees

30 + 120 = 150 degrees

A linear function has to be added or subtracted by the same number every time. The independent variable is x and the dependent variable is y.

So for side "x" 1 is being added to each number and for side "y"  is being subtracted by 2

Answer:

Choose f(x) = 11x + 1

Step-by-step explanation:

Note that we will simply plug the value of 2 into the equation for February:

f(2) = 11(2) + 1 = 23

And plug the value of 6 into the equation for June:

f(6) = 11(6) + 1 = 67

Note how the points on the graph seem to match up with these values.  If we evaluate following the same style for each:

f(3) = 11(3) + 1 = 34

f(4) = 11(4) + 1 = 45

f(5) = 11(5) + 1 = 56

Note, these values seems to be very close in approximation to the graph points for each month.

The other three functions return values that are just to far away from what are represented in the graph.

The percentage of 1 spig to 5 spug is 17.9%

What is percentage?

Percentages are essentially fractions where the denominator is 100.

40% of spig =1spoog

25% of speeg = 1 spoog

therefore 40%spig = 25% speeg

1 spig = 25/40 speeg

1 spig = 5/8 speeg

70% of speeg= 1 spug

70/100 speeg = 1 spug

therefore dividing both sides by 100/70

1 speeg = 100/70spug = 10/7spug

similarly 8/5 spig = 1 speeg

therefore 8/5 spig = 10/7 spug

divide both sides by 5/8

1 spig = 50/56 spug

percentage of 1 spig to spug =

89.3 % spug is 1 spig

therefore the percentage of 1 spig of 5 spugs is 89.3% /5 = 17.9%

Answer:

Sales= $90

Expenditures= $90

Step-by-step explanation:

The members of a cooking club are making cakes.

The cakes will be sold at a street fair price of $9 for each cake.

It cost $50 for a booth at the fair.

The ingredients for each cake cost $4

Let y represent the number of cakes that was sold

Since the price of each cake is $9 then,

Sales = $9y

Since the booth cost $50 and ingredients cost $4 then,

Expenditures = $50 + $4y

Sales = Expenditures

9y= 50 + 4y

Collect the like terms

9y-4y= 50

5y= 50

Divide both sides by the coefficient of y which is 5

5y/5= 50/5

y= 10

Sales= 9×10

= $90

Expenditures= $50 + 4(10)

= $50+$40

= $90

Hence the sales is $90 and the expenditures is $90
