Answer:

120 meters

Step-by-step explanation:

Bob's land is a rectangle, so it has 2 long and 2 short sides. The Long side is 40 meters long, and the short side is 20 meters long.

Let's add them: 40 + 20 = 60 meters

Since we have 2 of those sides, we will multiply it by 2 which we can demonstrate as

60 meters * 2 = 120 meters

Answer:

9

Step-by-step explanation:

2 ( ) = 18

Remember that bracket sign means multiplication. So, if we divide both sides by 2, we have

( ) = 18/2

( ) = 9

The missing integer is 9

Answer:

You first multiply the 2 with the numbers inside the parinthesis. So it'll be 2 x 2w and 2 x -9 which will get you to 4w-18. After that you add 18 to each side of the equation so the -18 can dissapear. After getting your answer you get left with 4w on the left side and -20 on the right. You then divide both sides with 4

Step-by-step explanation:

2(2w-9)=-38

4w-18= -38

    +18  +18

4w = -20

4w/4= w

-20/4= -5

So in the end W= -5

Answer:

The surface area of given cuboid is: 148 square centimeters

Step-by-step explanation:

Let

l = 5

w = 4

h = 6

The cuboid has 6 rectangular surfaces.

The surface area of a cuboid with height h, length l and width w is given by:

[tex]TSA = 2 ( lw+wh+hl )[/tex]

Putting the values

[tex]TSA = 2(5*4 + 4*6 + 6*5)\\= 2(20+24+30)\\=2(74)\\=148\ cm^2[/tex]

Hence,

The surface area of given cuboid is: 148 square centimeters

Answer:

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{19}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 6 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c , substitute (4, 5) into the partial equation

5 = - [tex]\frac{4}{3}[/tex] + c ⇒ c = 5 + [tex]\frac{4}{3}[/tex] = [tex]\frac{19}{3}[/tex]

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{19}{3}[/tex] ← equation of perpendicular line

Answer:

There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.

Step-by-step explanation:

There are theoretically three unique triangles that can be formed with two side lengths of 10 centimeters and one 40º angle. We include a representation of possible triangles:

Case A - Law of Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]C = 40^{\circ}[/tex])

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex] (1)

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 40^{\circ}}[/tex]

[tex]c\approx 6.840\,cm[/tex]

Case B - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]B = 40^{\circ}[/tex])

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex] (2)

[tex]\sin A = \frac{a\cdot \sin B}{b}[/tex]

[tex]A = \sin^{-1}\left(\frac{a\cdot \sin B}{b} \right)[/tex]

[tex]A = \sin^{-1}\left[\frac{(10\,cm)\cdot (\sin 40^{\circ})}{10\,cm} \right][/tex]

[tex]A = 40^{\circ}[/tex]

[tex]C = 180^{\circ}-A-B[/tex]

[tex]C = 100^{\circ}[/tex]

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]

[tex]c \approx 15.321\,cm[/tex]

Case C - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]A = 40^{\circ}[/tex])

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]

[tex]\sin B = \frac{b\cdot \sin A}{a}[/tex]

[tex]B = \sin^{-1}\left(\frac{b\cdot \sin A}{a} \right)[/tex]

[tex]B = 40^{\circ}[/tex]

[tex]C = 180^{\circ}-A-B[/tex]

[tex]C = 100^{\circ}[/tex]

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]

[tex]c \approx 15.321\,cm[/tex]

There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.

Answer:

  1 1/5

Step-by-step explanation:

We want to find the number of times (5/6) goes into 1, so we divide ...

  1/(5/6) = 1 × 6/5 = 6/5 = 1 1/5

There are 1 1/5 groups of 5/6 in 1.

_____

Another way to look at it

You can consider 1 to be divided into 6 equal part:

  o  o  o  o  o  o

We can group these in groups of 5, so each group is 5/6 of the whole:

 (o  o  o  o  o)  o

What we see is that we have 1 group, and 1/5 of another group.

That is, 1 has 1 1/5 groups of 5/6 in it.

Given:

Whiskers the cat weighs [tex]3\dfrac{1}{2}[/tex] kg and Pilglio weighs 5 kg.

To find:

How many times as heavy as pilglio is whiskers?

How many times as heavy as whiskers is pilglio?

Solution:

We have,

Weight of cat (whiskers) = [tex]3\dfrac{1}{2}[/tex] kg

                      = [tex]\dfrac{3(2)+1}{2}[/tex] kg

                      = [tex]\dfrac{7}{2}[/tex] kg

                      =  3.5 kg

Weight of pilglio = 5 kg

Now,

[tex]\dfrac{Whiskers}{Pilglio}=\dfrac{3.5}{5}=0.7[/tex]

Therefore, whiskers is 0.7 times as heavy as pilglio.

[tex]\dfrac{Pilglio}{Whiskers}=\dfrac{5}{3.5}[/tex]

[tex]\dfrac{Pilglio}{Whiskers}=1.428571...[/tex]

[tex]\dfrac{Pilglio}{Whiskers}\approx 1.43[/tex]

Therefore, piglio is about 1.43 times as heavy as whiskers.

Answer:

X=38

Step-by-step explanation:

this is an isosceles triangle as we can see by the lines on the sides of the triangle. that means both of those sides are equal to 52.

52x2=104

A triangle adds up to 180. If two of the sides already equal 104 then the last side will be how much will go up to 180.

180-104=76

It is cut by a bisector DB meaning both sides will be equal. So divide 76 by 2 and we get 38

I can't really tell if x is for one side of angle b or both sides. If it is only for one side then it is 38 but if it is for the whole angle B then it is 76.

Answer: x=4

Step-by-step explanation:

First, you need to take both of the x to one side of the equation. To do that, subtract 4x from both sides of the equation. you will get 9x-7-4x=4x+13-4x. The 4xs on the right hand side of the equation will cancel out. So you will be left with an equation that looks like this: 9x-7-4x=13. Now, on the left hand side of the equation you can rearrange the numbers to look like this. 9x-4x-7=13. Do 9x-4x to get 5x and then add back your -7 and the =13. Now, your equation will look like this. 5x-7=13. Now, you need to get rid of the 7 on the left hand side of the equation in order to isolate the variable (which is x here). The easiest way to do this would be to add 7 to both sides (in order to keep the equation balanced, whatever you do on one side of the equation has to also be done on the other side.) of the equation so the +7 and -7 could cancel each other out. You would have 5x-7+7=13+7. Now, cancel out the 7s on the left hand side of the equation. You would be left with 5x=13+7. Add the 13 and the 7 on the right hand side of the equation to get 20. You would now have the equation 5x=20. Finally, you need to isolate the x, right? To do that, just divide both sides of the equation by 5. you would get 5x/5=20/5. And your final answer after simplifying should be x=4. Hope this helps!

The area of a circle is given as πr².

The number of boxes of grass seeds required to cover the garden is 9 boxes.

A circle is a round-shaped figure that has no corners or edges. 

The area of a circle is given as:

Area = πr²

We have,

The radius of the circle = 10 m

Area of the garden:

= πr²

We can take,

π = 22/7 = 3.14

= 3.14 x 10 x 10

= 314 m²

The area of a box of grass seeds:

= 46 m²

The number of boxes of grass seeds to cover the garden area:

= 314 / 46

= 6.8 boxes

Thus,

The number of boxes of grass seeds required to cover the garden is 9 boxes.

Answer:

2.5 hours

Step-by-step explanation:

To get the hourly speed, we need to divide 430 by 5.

This means that the train is going at a speed of 86 miles/hour.

Since we need to find the hour, we need to divide 215 miles by 86 miles/hour.

[tex]215 miles / \frac{86 miles}{hour}[/tex]

We can use the keep change flip to do [tex]215 miles * \frac{1 hour}{86 miles}[/tex]

Answer:

3. Markup $3.50 Retail Price $13.50

4.)Markup $10 Retail Price $50

Answer:

3. $ Markup = $3.50

Retail Price = $13.50

4. $ Markup = $10

Retail Price = $50

Step-by-step explanation:

Turn the % markups into decimals. For 3, you would turn the % markup into 0.35 and for 4 you would turn the % markup into 0.25.

Multiply the decimals by the price. Your result for the $ markup for 3 should be $3.50 and the result for 4 should be 10.

Now add the $ markup to the original price for 3 and 4.

10 + 3.50 = $13.50

40 + 10 = $50

Answer:

2 - 1

Step-by-step explanation:

Answer: If the given slope is –6/5, the equation is

y –2 = –6/5(x -5)

The attachment shows the graph of this equation.

The point-slope form is y = –6x/5 + 8

Step-by-step explanation:  The basic form for a point-slope equation is

y - b = m(x - a)

a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.

The slope, m, is given: -6/5   Substitute for m

Given coordinate points ​(5,2) substitute the x-value in place of a and the y-value in place of b

Rewrite the equation:

y - b = m(x - a) becomes

y - 2 = –6/5(x - 5)
