Answer 1

Answer:

150

Step-by-step explanation:

z=5

x=9

y=3

plug the numbers into a calculator

(9-3)=6

5^2=25

25*6=150

Answer 2

Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.

Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.

To avoid the confusion of having too many sets of parenthses,

let's change the parenthses in the original problem to brackets.

Now let's substitute using parenthses.

So we have (5)² · [(9) - (3)].

Since the parenthses were in the original problem were replaced

by brackets and parenthses come first in your order of operations,

in our problem the brackets are going to come first.

So first simplify 9 - 3 which is 6.

So we have (5)² [(6)].

Exponents come next so we square the 5 to get 25

and that gives us (25) [(6)] which is 150.

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

Answers

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°

Carl sees 25 melons at the store. 15 are small and the rest are large. How many melons are large?

Answers

Answer: 10 large melons

Step-by-step explanation:

Carl saw 25 melons at a store.

Of these 25, 15 were small and the rest were large.

The number of large melons will have to be the whole total of 25 melons less the number of small melons which is 15:

= 25 total melons - 15 small melons

= 10 large melons

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.

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%

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
