Answer:

x = 2

Step-by-step explanation:

160 - 15x = 120 + 5x

160 - 120 - 15x = 120 - 120 + 5x

40 - 15x + 15x = 5x + 15x

40 = 20x

2 = x

x= 2

Answer:

It is not.

Step-by-step explanation:

[tex]15^{2}[/tex]+[tex]7^{2}[/tex]=225+49=274

[tex]16^{2}[/tex]=256

274≠256

Answer:

No, this triangle is not a right triangle

Step-by-step explanation:

If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem.  Otherwise it is not.

15^2 + 7^2 = 225 + 49 = 1225 = 35^2.  This is FALSE, and so:

No, this triangle is not a right triangle

Answer:

56 cm

Step-by-step explanation:

perimeter = the length of the sides.

4+5+5+5+4+10+13+10=56 cm

Answer:

56 cm

Step-by-step explanation:

The perimeter of a shape is just all the lengths added  together. So 5+5+5= 15 and 10+10+13=33 and 4+4=8. 15+33+8=56. Hence 56 is the answer

Answer:

A. distributive property

Answer:. Distributive property

Answer:The value of the 1 in the ones place is 10 times​ the value of the 1 in the tenths place.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

A=hbb

2

Solving forhb

hb=2A

b=2·29.7

13.5≈4.4

Answer:

1 cm

Step-by-step explanation:

We know that the formula for perimeter is 2(l+w) or l+l+w+w

We know that the height is 5 cm so that means w= 5 also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is 1 cm if you add the length together you 2 when you add the width you get 10. 10+2=12.

Answer:

90 yd's

Step-by-step explanation:

Volume= L * W * H

We know that the length is 10 yd's,

the width is 3 yd's and the height is 3 yd's

so.. You do 10*3*3= 30*3= 90 yd's

Answer:

C

Step-by-step explanation:

Since events A and B occur independently, it means that if A occurs, B May or May Not occur, vice versa. (basically, event A and B can occur on its own or together which are not dependent on the other event)

For probability of A and B to occur, and that probability of A / Probability of B occurring are not dependent on each other at any circumstance, u need to multiply the P(A) and P(B) to find out the chances of A and B occurring.

Answer:

x = 7

Step-by-step explanation:

The two triangles are similar by AA similarity.

6 : 36 = x : 42

1 : 6 = x : 42

x = 7

Answer:

Answer would be 7.

Step-by-step explanation:

Answer:

254.34 cm^2

Step-by-step explanation:

Volume of cylinder = [tex]\pi r^{2} h[/tex]

We know that the diameter is 6, which means that the radius is 3 cm.

Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.

Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.

Substituting into the formula we will end up with 254.34 cm^2.

So the right answer is -3/2

Answer:

x =

Step-by-step explanation:

-5(4x + 2) = 20

First you distribute

-20x - 10 = 20

Add 10 to both sides to single out 'x'

-20x = 30

Divide by the coefficient of x

-20x/-20 = 30/-20

solve

x = -3/2

or

x = -1.5

Answer:

Mark makes $12 an hour. Steven makes $15 an hour.

Step-by-step explanation:

s = steven's hourly pay

m = mark's hourly pay

s = m + 3

5s + 6m = $147

5 (m + 3) + 6m = $147

5m + 15 + 6m = $147

11m = $132

m = $12

s = m + 3

s = 12 + 3

s = $15

Answer:

since lisa earns half of what mary does divide 62 into 2 which is 31

and she has 8 students.

she is paid twice as much in students, so lisa would earn more due to getting paid more with having more students, as she gets paid twice the amount from students she has, and if she had 20 she would get paid 40 but if you add 2x of the mass it will be 80, and mary will have 40.

if its incorrect i apologize.

Answer:

3x² - 6

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= 2x² + 1 + x² - 7 ← collect like terms

= 3x² - 6

one circle is equal one

so the first total is 11

so you minus five from the total

11-5

=6

so there are two triangle so divide the answer by two

=6/2

Answer:

38

Step-by-step explanation:

Since x is an inscribed angle in a circle, its value will be half of the value of its respective arc. Since the measure of its arc is 76, the value of x is 76/2=38. Hope this helps!

Answer:

D

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'm going to paint you a picture in words of what this looks like on paper.  We have a train leaving from a point on your paper heading straight west.  We have another train leaving from the same point on your paper heading straight east.  This is the "opposite directions" that your problem gives you.  

Now let's make a table:

                distance       =        rate      *       time

Train 1

Train 2

We will fill in this table from the info in the problem then refer back to our drawing.  It says that one train is traveling 12 mph faster than the other train.  We don't know how fast "the other train" is going, so let's call that rate r.  If the first train is travelin 12 mph faster, that rate is r + 12.  Let's put that into the table

              distance        =        rate        *        time

Train 1                                        r

Train 2                                    (r + 12)

Then it says "after 2 hours", so the time for both trains is 2 hours:

              distance        =        rate        *        time

Train 1                                        r           *          2

Train 2                                  (r + 12)       *          2

Since distance = rate * time, the distance (or length of the arrow pointing straight west) for Train 1 is 2r.  The distance (or length of the arrow pointing straight east) for Train 2 is 2(r + 12) which is 2r + 24.  The distance between them (which is also the length of the whole entire arrow) is 232.  Thus:

2r + 2r + 24 = 232 and

4r = 208 so

r = 52

This means that Train 1 is traveling 52 mph and Train 2 is traveling 12 miles per hour faster than that at 64 mph

In the first image, notice that the figure is a cube

also known as a "square prism."

Since a cube is composed of square bases, we

want to find a net that is composed of all squares.

Notice that the option of the bottom left is composed of squares.

So this net matches the figure.

52.68 feet per 60 min

632.16 inches per 60 min

10.536 inches per minute

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area of circle = πr²  = 15 m²

Volume of Cylinder = πr²h

                                = 15 * 3

                                = 45 m³

Volume of Cone = (1/3)πr²h

[tex]=\frac{1}{3}*15*3\\\\[/tex]

= 15 m³

Answer: x = 2

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4(x) which is 4x and 4(6) which is 24.

So our equation now reads 4x + 24 = 32.

Solving from here, we subtract 24 from both sides to get 4x = 8.

Then divide both sides by 4 to get x = 2.

Answer:

a = - 2, b = 4, c = - 3

Step-by-step explanation:

The standard form of a quadratic equation is

ax² + bx + c = 0 ( a ≠ 0 )

Compare  - 2x² + 4x - 3 = 0 to the standard, giving

a = - 2, b = 4, c = - 3

Answer:

See below in bold.

Step-by-step explanation:

-2x^2 + 4x  - 3 = 0     Compare this with the standard form:

ax^2  + bx + c = 0

We see that a = -2, b = 4 and c = -3.
