Answers:

b)  92100 decimeters

c)   6650 decaliters

=====================================================

Work Shown for part b)

1 decameter = 10 meters

1 decimeter = 1/10 of a meter

10 decimeters = 1 meter .... multiply both sides by 10

100 decimeters = 10 meters ... multiply both sides by 10

100 decimeter = 1 decameter

921*(100 decimeter) = 921*(1 decameter)

92100 decimeters = 921 decameters

-------------------

Work Shown for part c)

We could follow the same idea as part b). I'm going to use another approach as shown in the diagram below. This conversion method is known as the railroad tracks method in some math textbooks.

Each column represents two things that are equivalent to one another. For example, 1 kiloliter is the same as 1000 liters. So each column, when you divide top over bottom, represents the value 1.

Notice the unit cancelations as shown by the color coding. The goal is to have every unit cancel except for the decaliters unit which is what we want to end up with ultimately.

Once you have the railroad tracks set up, you multiply straight across.

Along the top, we have 66.5*1000*1 = 66500

Along the bottom we have 1*10 = 10

Divide those results: 66500/10 = 6650

So 66.5 kiloliters converts to 6650 decaliters

Order of Operations: BPEMDAS

Step-by-step explanation:

We must follow BPEMDAS rules.

We first look at the parenthesis, and evaluate it left to right. In the parenthesis, the first order of higher operation would be division, hence B is our answer.

Answer:

50 pounds.

Step-by-step explanation:

25000 / 500 = 50 pounds.

Answer:

50

Step-by-step explanation:

25,000 / 500 = 50

Answer:

8 pounds

Step-by-step explanation:

x represents the starting amount

5 = 3x/8 + x/4

40 = 3x + 2x     multiply both sides by LCD, 8

40 = 5x

x=8

Answer:

p > 16/5

Step-by-step explanation:

-5p<-16

Divide each side by =5, remembering to flip the inequality

-5p/-5 > -16/5

p > 16/5

There is an open circle at 16/5 and the lines goes to the right

Answer:

[tex]- \frac{1}{5} xy -\frac{4}{5} xy \\ = { \tt{( - \frac{1}{5} - \frac{4}{5} )xy }} \\ \\ = { \tt{ - xy}}[/tex]

Answer:

U = -3

Step-by-step explanation:

U/-1 +-4=-1

Add 4 to each side

U/-1 +-4+4=-1+4

U / -1 = 3

Multiply each side by -1

U / -1  * -1 = 3* -1

U = -3

Answer:

[tex]x=0[/tex] and [tex]x=\pm\sqrt{3}[/tex]

Step-by-step explanation:

[tex]f(x)=x^5-3x^3[/tex]

[tex]0=x^5-3x^3[/tex]

[tex]x^5-3x^3=0[/tex]

[tex]x^3(x^2-3)=0[/tex]

[tex]x^3=0[/tex] and [tex]x^2-3=0[/tex]

[tex]x=0[/tex] and [tex]x=\pm\sqrt{3}[/tex]

m<A = 114° , m<Q = 114° , m< D= 66° ,m<U = 66°

x=13

FIRST THREE OPTIONS

A,B,C

Answer:

[tex]x = 13[/tex]

[tex]m<Q = 114°[/tex]

[tex]m<D = 66°[/tex]

Step-by-step explanation:

First option :

[tex](5x+1)=(6x−12)[/tex]

[tex]5x+1−6x=−12[/tex]

[tex]−x+1=−12[/tex]

[tex]−x=−12−1[/tex]

[tex]−x=−13[/tex]

[tex]x=(−13) \times (−1)[/tex]

[tex]x = 13[/tex]

Second option :

<D = 6(13) - 12

= 78 - 12

= 66°

Third option :

<A + <D = 180°

<D = 180 - 66

= 114°

Answer:

[tex]-x[/tex]

Step-by-step explanation:

[tex]3x-4x = -1x[/tex]

Replace x with 180:

54

Answer : 54

Answer:

54

Step-by-step explanation:

x = 18

Evaluate:

3 x / 10

put the value of x

3 × 180 / 10

540 / 10

54

Answer:

f(- 3) = 18

Step-by-step explanation:

Substitute x = - 3 into f(x) , that is

f(- 3) = 2(- 3)² = 2(9) = 18

================================================

Explanation:

Draw a vertical line through 5 on the x axis. This represents the equation x = 5. Notice that we intersect the blue line at (5,-1) which tells us that f(5) = -1. There's a closed point here, meaning that the point is included. This is in contrast to the open hole at (5,3) which is not part of the function. So be careful not to say that f(5) = 3 because that's not the case.

Answer:

i think it's f(5) - a wild guess

Answer:

$78.94

Step-by-step explanation:

15% = 0.15

multiply to the total (68.65)

0.15 × 68.65 = 10.2975

$68.65 + 10.2975 = $78.94

Answer:

B. Vertical Angles

D. Supplementary

Answer:

a is to the right of b. On a number line the orientation has 0 as the starting number and counts on each whole number integer on to the eight. Therefore if a is greater than b, be will be toward the left and a will be toward the right.

The undefined term is point.

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.

Parts of an Angle

There are two main parts related to an angle - the arms and the vertex.

Arms of the Angle

The two rays which join at a common point to form the angle are called the arms of the angle. Observe the figure given below which shows that OA and OB are the arms of the angle AOB.

[tex]vertex[/tex]of the angle

[tex]vertex[/tex] is a common endpoint that is shared by the two rays. Observe the figure in which the [tex]vertex[/tex] O is marked as the joining point of the two arms.

Measure of an angle

An angle is measured in degrees. One full rotation around a point forms a complete angle of 360°.

As, the is defined on the basis of arms , vertices, measurement.

They all related to point and point doesn't have a particular definition.
