150 memos for 3 typists

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

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

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

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%

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

Answer:

Amount left in the container is [tex]400\:\text{kg}[/tex].

Step-by-step explanation:

Given: A container holds [tex]600[/tex] kg of rice.  [tex]33 \frac{1}{3} \%[/tex] of rice was distributed to groceries.

To find: How many kilograms of rice remained in the container?

Solution:

We have,

Amount of rice in the container [tex]=600[/tex] kg

Amount distributed to the groceries [tex]=33 \frac{1}{3} \%= \frac{100}{3}\%[/tex]

Therefore, amount distributed to groceries[tex]=\frac{100}{3}\times\frac{1}{100}\times600=200 \:\text{kg}[/tex]

Now, amount of rice left in the container[tex]=600\:\text{kg}-200\:\text{kg}=400\:\text{kg}[/tex]

Hence, amount of rice left in the container is [tex]400 \:\text{kg}[/tex].

Answer:

Option B

Step-by-step explanation:

From the picture attached,

Area of the one side of the roof = Area of the rectangle

                                                     = Length × Width

                                                     = AE × AC

To get the length of side AC, construct a perpendicular AD on side BC which divides BC in two equal parts.

BD = DC = 13 ft

By applying cosine rule in ΔADC,

cos(45)° = [tex]\frac{\text{DC}}{\text{AC}}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{13}{\text{AC}}[/tex]

AC = 13√2

AC = 18.38 ft

Therefore, area of one side of the roof = 38 × 18.38

                                                                 = 698.62 square feet

Area of both the sides of the roof = 698.62 × 2

                                                        = 1397.24 feet²

                                                        ≈ 1397 feet²

Option B will be the answer.

The total area of the roof to the nearest square foot is 1,397 square feet

In order to get the area of the roof, we will need the slant height of the triangle.

Using the pythagoras theorem;

[tex]cos45 = \frac{26/2}{l} \\cos 45 = \frac{13}{l} \\0.7071 = \frac{13}{l} \\l = \frac{13}{0.7071} \\l=18.39 feet[/tex]

Area of the roof = 2(lw)

Area of the roof = 2(38 * 18.39)

Area of the roof = 1,397.64

Area of the roof ≈ 1,397 square feet

Hence the total area of the roof to the nearest square foot is 1,397 square feet

Answer:  C.  1/r^10

Step-by-step explanation:

when you are dividing two exponents, you have to subtract them.

Subtract numerator by denominator: 2 - 12 = -10

when you have negative exponent you have to put a one at the numerator

Answer: 1/r^10

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.

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

Answer:

Then the answer to the system is the point (-1, 3)

which corresponds to x = -1 and y = 3

Step-by-step explanation:

Start by dividing the first equation by 3 on both sides, and get:

x + y = 2

now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:

5 x + 5 y = 10

+

9 x - 5 y = - 24

___________

14 x + 0 = -14

solve for x by dividing both sides by 14:

x = -14/14 = -1

Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:

-3 + 3 y = 6

add 3 on both sides:

3 y = 9

divide both sides by 3 to isolate y:

y = 3

Then the answer to the system is the point on the plane (-1, 3)

which corresponds to x = -1 and y = 3

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.
