Explanation:

Use of a calculator will show that

2/3 = 0.6666...

where the 6's go on forever. Your teacher only wants 2 significant figures though. That means you'll round to the nearest hundredth to get 0.67

The 0 to the left of the decimal point is not a significant figure. The reason being is because we can rewrite 0.67 into 6.7*10^(-1); we can see the coefficient 6.7 having two sig figs.

Answer:

30 dólares es la ganancia neta.

Step-by-step explanation:

En la primera transacción, el hombre está perdiendo 50 dólares:

1. -50 dólares

En la segunda transacción, el hombre gana 70 dólares:

2. -50 + 70 = +20 dólares

En la tercera transacción pierde 80 dólares:

3. 20 - 80 dólares = -60 dólares

Y en la última transacción, la ganancia es de 90 dólares. Así, la ganancia neta es:

4. -60 dólares + 90 dólares =

Answer:

103

Step-by-step explanation:

Find the area of the rectangle on the top

A = 7*13 = 91

Now find the area of the rectangle on the bottom

13 - (5+5) = 3

11-7 = 4

The dimensions of the bottom rectangle are 3 by 4

A = 3*4 = 12

The total area is 91+12 = 103

Answer:

[tex]Base\ Area = 93ft^2[/tex]

Step-by-step explanation:

Given

[tex]Volume = 279ft^3[/tex]

[tex]Height =3ft[/tex]

Required

The base area

Volume is calculated as:

[tex]Volume = Base\ Area * Height[/tex]

This gives:

[tex]279= Base\ Area * 3[/tex]

Make Base Area the subject

[tex]Base\ Area = \frac{279}{3}[/tex]

[tex]Base\ Area = 93ft^2[/tex]

Answer:

A. It increased both her intensity and her workout time.

Step-by-step explanation:

A. It increased both her intensity and her workout time.

B. It decreased her intensity but increased her workout time.

C. It increased her intensity but decreased her workout time.

D. It decreased both her intensity and work out time

Last week = 4 miles per day

This week = 5 miles per day

Intensity refers to how hard one exercises.

Workout time refers to how long one exercises the body.

By adding a mile, she has increased how hard she exercises her body (intensity))

And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day

Answer:

77

Step-by-step explanation:

180-61-42

Answer:

x = 77°

Step-by-step explanation:

the total among these angles are 180° so add 61 + 42 which equals 103 then subtract it from the total

180° - 103° = 77°

x = 77°

Answer:

Angle g = 90°

Angle between x and G = 30°

Angle x= 180-(90+30)

= 180-120=60°

Answer:

D - x=y/12

Step-by-step explanation:

So lets just take one set of data from the table.

This is all we need.

So I am just going to set our values to:

x = 21

y = 252

Now lets plug this into each equation, ands ee if it is accurate or not:

21=12+252

=

21=264

Thats not right! Lets try the next one:

21 = 252/12

=

21 = 21

Thats correct! Lets just try the other ones anyway:

21 = 252 - 12

=

21=240

Thats not right! Lets try the last one:

21 = 12*252

=

21 = 52,424

That is most definatly not right!

So the answer is B, x=y/12

Hope this helps!

Step-by-step explanation:

there are 18 dogs

Answer:

14

Step-by-step explanation:

So the ratio of dogs (2) to cats (5) is 2:5

How did we go from 5 to 35?

Multiply by 7

So multiply 2 with 7 which is 14

So there are 14 dogs

Answer:

60

Step-by-step explanation:

If it is an equilateral triangle the sides are equal

24-x = 5x

Add x to each side

24-x+x = 5x+x

24 =6x

Divide by 6

24/6 =6x/6

4 =x

Each side is 5x or 5*4 = 20

Add the 3 equal sides

20+20+20 = 60

The perimeter is 60

Answer:

60

Step-by-step explanation:

In this case, to find the perimeter, we need to know the value of at least one side.

Since this triangle is equilateral, [tex]5x=24-x[/tex].

Adding x to both sides results in [tex]6x=24[/tex], and subsequently, [tex]x=4.[/tex]

Now that we know x equals 4, we can plug this into either 5x or 24-x and find out that one of the sides is 20.

Equilateral triangles have three equal sides, so 20 times 3, or 60, is the perimeter. I hope this helped!

Answer:

b = 5

Step-by-step explanation:

You want to get b on one side alone so you divide by 4.

20 divided by 4 is 5.

Answer:

b = 5

Step-by-step explanation:

4b = 20

Whatever we do to one side of the equation, we have to do to the other.

To "isolate the variable", or get "b" by itself, we have to divide both sides by 4

4b divided by 4 is b, since "4b = 4 times b"

20 divided by 4 is 5

4b = 20

b = 5

The graph of the linear equation can be seen below.

Here we have the linear function:

y = 5x + 3

To graph this, we need to find two points on the equation and then connect them with a line.

By evaluating in 0 we get:

y = 5*0 + 3 = 3

So the point (0, 3) is on the line.

By evaluating on 1 we get:

y = 5*1 + 3 = 8

So we have the point (1, 8).

Now we just plot them and connect them with a line, the graph is the one below.
