Answer:
The newspaper has 500 readers.
Step-by-step explanation:
We have that:
10 people is 2$ of all newspapers readers, which total t. This means that:
[tex]0.02t = 10[/tex]
[tex]t = \frac{10}{0.02}[/tex]
[tex]t = \frac{1000}{2}[/tex]
[tex]t = 500[/tex]
The newspaper has 500 readers.
If I have 50 envelopes I put equal amounts of money in each one how much will I have at the end of 50 days
Answer:
At the end of 50 days , Amount of money = $2500x
where x is the value that added every day.
Step-by-step explanation:
Let daily amount added in 1 envelope = $x
As, we have 50 envelope,
so, daily added amount in 50 envelope = $ 50x
⇒ Each day , we add money = $ 50 x
After 50 day, it becomes $50×50x = $2500x
For example -
If we add $ 1 every day in each envelope
then ,
Total amount added in 50 envelope each day = $50×1 = $ 50
Then,
After 50 days,
Total amount = $ 50×50 = $2500
∴ we get
At the end of 50 day, total amount we have = $2500
What is the product of (3x + 1)(3x – 4)?
Step by step.
Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
Answer:
9x^2 - 9x - 4
Step-by-step explanation:
(3x + 1)(3x – 4)
Here you can use the FOIL method (FOIL stands for: First, Outer, Inner and Last)
First you multiply 3x by 3x since these are the First inside both binomials.
3x * 3x = 9x^2
Then you multiply 3x by -4 since these are the Outer inside both binomials.
3x * -4 = -12x
Then you multiply 1 by 3x since these are the Inner inside both binomials.
1 * 3x = 3x
Then you multiply 1 by -4 since these are the Outer inside both binomials.
1 * -4 = -4
And finally add everything together:
9x^2 + (-12x) + 3x + (-4)
Since adding a negative number is the same as subtracting it:
9x^2 - 12x + 3x - 4
We can now simplify this a little by adding all the x's together:
9x^2 - (12x + 3x) - 4 =
9x^2 - 9x - 4
Hope I could help you understand!

Write a linear equation that represents the area and a linear equation that represents the perimeter of the rectangle.
(3x-3) cm and
6 cm
I need a linear equation for for area and a linear equation for perimeter.
Answer:
Assuming that (3x - 3) and 6 are the sides of the rectangle,
Area:
A = l × w
y = (3x - 3) × (6)
y = 18x - 18
Perimeter:
P = 2l + 2w
y = 2(3x - 3) + 2(6)
y = 6x - 6 + 12
y = 6x + 6
The required linear equation for the area and perimeter of the rectangle is y = 18[x - 1] and z = 6[x + 1] respectively.
Given that, to determine the linear equation that represents the area and a linear equation that represents the perimeter of the rectangle.
The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
here,
Length = 3x + 3
Width = 6
Area of the rectangle = y, = length × width
y = [3x - 3 ] × [6]
y = 18x - 18 = 18[x -1]
Perimeter of the rectangle = 2[length + width]
z = 2 [3x - 3 + 6]
z = 2 [3x + 3]
z = 6[x + 1]
Thus, the required linear equation for the area and perimeter of the rectangle is y = 18[x - 1] and z = 6[x + 1] respectively.

In a store, 7/200 of the shirts are yellow and 69/600 are pink . What percent of the shirts are not yellow or pink.?
Answer:
510/600 of the shirts are not yellow or pink.
Step-by-step explanation:
First we turn 7/200 with a denominator of 600.
7/200 = 21/600
Next we add 69/600 with 21/600.
69/600 + 21/600 = 90/600
Now we subtract 600 by 90.
600 - 90 = 510.
So, the answer is 510/600

What is the equation of the line that includes the points (1,6) and (2,8)?
Answer: y = 2x + 4
Step-by-step explanation:
y = mx + b
(1,6) and (2,8)
Finding Slope:
(8 - 6) / (2 - 1)
=> 2/ 1 or 2
y = 2x + b
Finding "B":
y = 2x + b
=> 6 = 2(1) + b
=> 6 = 2 + b
=> b = 4
so y = 2x + 4

The point-slope form of the equation of the line that passes through (44, -3) and (12, 1) is y-1 = (x - 12). What is
the standard form of the equation for this line?
Answer:
-y+(x-12)=-1
Step-by-step explanation:
Write an equation in point-slope form of the line that passes through the point (5, 6) with slope 3/5
Answer:
(y - 6) = 3/5(x - 5)
Step-by-step explanation:
First, let's look at what point-slope form is: (y - y₁) = m(x - x₁)
Let's plug in the vallues we know.
m is the slope: 3/5
x₁ is 5
y₁ is 6
Therefore:
(y - 6) = 3/5(x - 5)
This is your equation.

because use dimas ruleonly like terms can be subtract and addHow can you use similar triangles to solve problems?
Answer:
you can use similar triangle to make known degrees in problems to make then easier to solve. With similar triangle, the angles are the same, but the scale is different. So by using this, one can solve both at the same time, and just just scale up the smaller one or scale down the larger, by the given/found scale.
Step-by-step explanation:
Answer:
You can indirectly determine the measure or size of something that is tedious to measure by hand.
Or by knowing that the triangles are similar, you can find the corresponding sides, angles or even other variables based on the information that is given.
If a triangle is similar to another, they are proportional; usually have congruent angles, which means that the only differing variable is the scale factor, or relative position.

4. 5.75%
5. $15,785
6. $20,960
Step-by-step explanation:
I (interest) = p(principal, or money deposited) x r (rate, converted from percentage to decimal) x t (time, in years)
Plugging in info for #4:
241.50 = (1,050) (r) (4)
241.50 = 4200r
divide both sides by 4200
r = 0.0575
multiply by 100 to change from decimal to percentage, = 5.75% is the rate
Plugging in for #5:
(remember to divide percentage by 100 to go from percent to decimal)
I = (410,000)(0.0385)(1)
Interest = $15,785
Number 6 takes two steps. One is the equation we've been doing, the other is to add that interest to the amount deposited in the first place.
I = (8,000)(0.09)(18)
Interest = $12,960
Now add the $12,960 to the $8,000 deposit in the first place, and you have $20,960
Calcule o saldo de salário, o funcionário foi admitido em 10 de janeiro como mensalista, salário R$ 1400,00?
Responda:
$ 980
Explicação passo a passo:
Dado que:
Salário mensal = $ 1400
Data de emprego = 10 de janeiro
Usando o sistema de mês de 30 dias:
Taxa diária =. $ 1400/30 = $ 46.66666
Dias não trabalhados = janeiro - 9 de janeiro = 9 dias
Subtraia o salário de 9 dias do total:
Salário total - (9 * taxa diária)
$ 1400 - (9 * $ 46,66666)
$ 1400 - $ 420
= $ 980
Portanto, o saldo do salário é de $ 980

Solve log x = 3
a. x=3
b. x=30
c. x=1,000
d.x=10,000
Answer:
c. x=1,000
Step-by-step explanation:
log x = 3
Imagine that it's log10 x = 3
So, x = 10^3 (10 to the third power)
x = 10 * 10 * 10
x = 1,000
Find the selling price of a $20 item after a 20% markup.
Answer:
$24
Step-by-step explanation:
For a markup, use the formula a = ( 1 + p ) × w.
!!! Remember, a is the selling price, and w is the original price !!!
!!! The p is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!
Inserting the values, it should look like a = ( 1 + 0.20 ) × 20
a = 1.20 × 20
a = 24
Hence, the new selling price is $24.
Hope this helps! :)
