Write The Following Using Algebraic Notation, Using The Letter X For Any Unknown Numbers:i Think Of A

Answers

Answer 1

Answer:

1/2x-4

Step-by-step explanation:

Since we don't know the number (unknown) we simplify it as a variable, x.

Then since you're taking half of x, place 1/2 next to x. Finally subtract 4, and it concludes to 1/2x-4.

you know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)
because you are finding the angle you would go Tan^-1(12÷20) =31°
it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20
Your answer is 31°

The ratio of Rogers age to his sons is 7:3. If the sum of their ages are 60 how old is Rogers son

Answers

Answer:24

Step-by-step explanation:

Sum of their ages is 60 yr. As such

7x + 3x = 60

10x = 60

x = 60 / 10

x = 6

The rationale is 6, therefore

Father's age is 7x = 7 × 6= 42 years

Son's age is 3x = 3 × 6 = 18 years

Difference in their ages

42 - 18 = 24 years

350 students signed up what percent signed up for the airforce (64)

Answers

Answer: 18.29%

Step-by-step explanation:

There are 350 students. Out of these students, 70 signed up for the Army, 64 for the Airforce, 56 for the Navy and 160 for the Marines for a total of 350.

The percentage of students who signed up for the Airforce out of the total can be calculated by:

= number of students (airforce) / total number of students * 100

= 64/350 * 100

= 18.29%

A scale of 1:20 is used to make the drawing of a car if the length of the drawing is 10 what is the real length of the car?

Answers

Answer: 200

Step-by-step explanation:

since 10 is one part

10 x 20 = 200

The real length of the car will be 200 units.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A scale of 1:20 is used to make the drawing of a car.

And, The length of the drawing is 10.

Now,

Since, The length of the drawing is 10.

And, The used scale = 1 : 20

Hence, The real length of the car = 20 × 10

                                                    = 200 units

The y intercept is 7 and the slope is

( 0,7) and (2,3)

m = ( 3-7)/( 2-0) = -4/2 = -2

y = -2x+7

Changing this to an inequality

y < -2x+7

Four typists can type a total of 600 memos in three days. At that rate, how many memos can three typists type in one day?

Answers

150 memos for 3 typists

The number of memos three typists can type in one day is given by the equation A = 150 memos

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of memos three typists can type in one day be A

Now , the equation will be

The number of typists = 4

The total number of memos by 4 typists = 600 words in 3 days

So , the number of memos by one typist for 3 days = total number of memos by 4 typists / 4

Substituting the values in the equation , we get

The number of memos by one typist for 3 days = 600/4

The number of memos by one typist for 3 days = 150 memos

So ,

The number of memos by one typist for 1 day = number of memos by one typist for 3 days / 3

Substituting the values in the equation , we get

The number of memos by one typist for 1 day = 150/3

The number of memos by one typist for 1 day = 50 memos

So ,

Number of memos three typists can type in one day A = number of memos by one typist for 1 day x 3

Substituting the values in the equation , we get

Number of memos three typists can type in one day A = 50 x 3

Number of memos three typists can type in one day A = 150 memos

Therefore , the value of A is 150 memos

Hence , the number of memos is 150 memos

Write an equation in slope-intercept form of the line that passes through the points (2, 4) and (3,6).

Answers

Answer:

[tex]y=2x[/tex]

Step-by-step explanation:

We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).

So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).

The slope formula is given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, by substitution, our slope is:

[tex]\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2[/tex]

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

By substitution:

[tex]y-(4)=2(x-(2))[/tex]

Distribute:

[tex]y-4=2x-4[/tex]

Adding 4 to both sides yields:

[tex]y=2x[/tex]

And we have our equation.

In this case, the y-intercept is 0.

evaluate the expressions. ​
