Answer:
30 tiles need to buy for same cost in both store.Step-by-step explanation:
Let x be the number of tiles to buy for same cost in both store.
18+0.69 · n = 1.29 · n,
1.29n -0.69n =18 or
0.6n =18
n =18/0.6=30
Therefore, 30 tiles need to buy for same cost in both store.[Ans]
Answer:
I think you need to cross multiply

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation

Answer: 14401.25
Step-by-step explanation:
Answer:
562000
Step-by-step explanation:
commission=commission rate multiplied with selling price
suppose selling price as x
14050=2.5% . x
14050=(2.5/100) . x
14050 . 100= 2.5 . x
x = 1405000/2.5
x=562000
A saleswoman is paid $80 a day plus $6 for each sale she makes. She wants to earn more than $150 today. Write an inequality that represents the number of sales, x, the saleswoman must make today to earn more than $150. What is the least number of sales she must make to reach her sales goal
Answer:
12
Step-by-step explanation:
Given that:
Daily wages paid to a saleswoman = $80
Wages paid for each sale made by her = $6
Target of today's earnings = more than $150
To find:
Least number of sales to be made so that the total earnings today is more than $150.
Solution:
Number of sales for today = [tex]x[/tex]
Wages for one sale = $6
Wages for [tex]x[/tex] number of sales = $6[tex]x[/tex]
Total earnings = Per day sales + Wages for [tex]x[/tex] number of sales > $150
[tex]80 + 6x > 150[/tex]
we need to solve for above inequality to find the least number of sales to be made to meet the goal.
Subtracting 80 from both sides:
[tex]\Rightarrow 6x>70\\[/tex]
Dividing both sides by 6:
[tex]\Rightarrow x > 11[/tex]
Therefore, at least 12 sales must be made.
Solve for X showing every step
Answer:
x = 1
Step-by-step explanation:
3(x + 6) -5 = 16
You want to first add the 5 (*flipping the sign) over to the 16
making your equation ...
3(x +6) = 21
Then you want to distribute the 3 to x and 6
making you equation
3x + 18 = 21
Then you want to subtract the 18 (*flipping the sign) to the right side
making the equation....
3x = 3
Lastly, divide the 3 on the left to the 3 on the right making the answer 1
x = 1

Sean is getting balloons for his grandfather's birthday party. He wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Sean wants to get 66 balloons, how many yards of string will he need?
Answer:
198 yards
Step-by-step explanation:
Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.
The total length of stings required for 66 balloons would be;
total length of balloon strings = 66 x 9 feet
= 594 feet
But the string is sold by the yard at the store.
So that,
1 yard = 36 inches = 3 feet
x yard = 594 feet
Thus,
x = [tex]\frac{594}{3}[/tex]
= 198 yards
x = 198 yards
Therefore, the total length of string that Sean would need is 198 yards.

p(green,green)=
Step-by-step explanation:
P(two green candies)
15 candies in total
5 green/15 total
which is equal to 1/3
left over candies= 13 because we are removing 2 green from the total
A line is perpendicular to the line given by the equation - 8 = 2y + 3x. What is the slope of the perpendicular line? 3
Answer:
2/3 is the slope of the perpendicular line
Step-by-step explanation:
1) put into slope-intercept form (y=mx+b)
-8=2y+3x
-2y=3x+8
y=-3/2x-4
2) the line is perpendicular so the slope will be opposite and the reciprical of the original slope.
so, because the original was -3/2, the new one is 2/3

What is gross income? Gross income is money earned before taxes are taken from a paycheck. Gross income is money earned after taxes are taken from a paycheck. Gross income is money paid to fund firefighters and police officers. Gross income is money paid for taxes.
Answer:
Gross income is money earned before taxes are taken from a paycheck
Step-by-step explanation:
Gross income is money earned before taxes are taken from a paycheck
Gross income refers to the total amount of money earned by an individual over a specific period of time usually a year before any deductions such as taxes is made.
Gross income includes income earned from all sources. It can also be called Gross pay on a paycheck.
For example, if an individual earns $100 in a year and is expected to pay a tax of 2%. The gross income is $100 before tax is deducted

Slope formula: y2-y1/x2-x1
Step-by-step explanation:
8-6/9-6= 2/0
Answer:
Step-by-step explanation:
Alright we need to prove that both the triangles are similar so lets get started
The slope formula is:
Slope = Change in y / Change in x
m = Δy / Δx
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]
Where, m is the slope and [tex](x_1,y_1) , (x_2,y_2)\\[/tex] are any points on the line
In this graph we are given three points which are
(0 , 2) , ( 6 , 6) and (9 , 8)
So for our first triangle we use the 2 points (0 , 2) and (6 ,6) and calculate the slope,
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{6-2}{6-0}\\\\m=4/6\\\\m=2/3\\[/tex]
So the slope turns out to be 2/3 , Now for our second triangle use the 2 points (6 , 6) and (9 , 8)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-6}{9-6}\\\\m=2/3\\[/tex]
So we can see the the slope's are equal that's the answer to your first part.
Second part
Yes they are similar due to the property of corresponding angles where angle x of the first triangle equals angle x for the second triangle and angle y for the first triangle equals angle y for the second triangle and both the triangles have 90° se they are similar because all three angles are similar. (AAA = angle angle angle property) I have attached a to make you understand it better.
