A triangle is 20 in tall and 5 in wide. If it is reduced to a width of 1 in then how tall will it be?
Answer:
4 inches tall
Step-by-step explanation:
To find how tall it will be, use the same reduction scale that was used to reduce the width.
This scale is 5, since 5 divided by 5 is 1.
So, to find how tall it will be, divide 20 by 5:
20/5
= 4
So, it will be 4 inches tall
6x-6y=23 find y when x=8
Answer:
y= 4.166
If rounded to the nearest tenth
y = 4.2
Step-by-step explanation:
6x - 6y = 23
x = 8
6x - 6y = 23 (Sub in the x with 8)
6(8) - 6y = 23
48 - 6y = 23 (Subtract each side by 48)
-6y = 23 - 48
-6y = -25 (Divide each side by -6)
y = 4.166
If rounded to the nearest tenth
y = 4.2

Juan wants to buy some protein bars and magazines for a trip.
He has decided to buy three times as many protein bars as
magazines. Each protein bar costs $0.70 and each magazine
costs $2.50. The sales tax rate on both types of items is 734%.
How many of each item can he buy if he has $20.00 to spend?
What Is the answer I don’t know
Answer:
HI there! I am really sorry if i get this wrong, but please apperciate!
Thank you! :)
Step-by-step explanation:
So I worked this out like this:
Protein bars: 0.70 * 3 = 2.1
Magezines: 2.50
734% are the taxes as it was written. 734% decimal version is 7.34.
This is what I did next:
7.34 plus 2.1 times 2 equals 18.88. So, you can buy 2 protein bars.
7.34 plus 2.50 times 2 equals 19.68. So, you can also buy 2 magazines!
I hope this helps! Let me know if this is wrong. Thanks and have a nice day!

Help tell me how Pi is found
Answer:
The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi. Leaving them with a infinte number 3.14159... and so on.
Step-by-step explanation:
Answer:
How was Pi discovered?
Here's a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation.
How is PI value calculated?
In some ways Pi (π) is a really straightforward number – calculating Pi simply involves taking any circle and dividing its circumference by its diameter. In fact if you search long enough within the digits of Pi (π) you can find any number, including your birthday.

If three independent events happen one after the other, which of the following sample space tools cannot be used?
a list
a tree diagram
a table
If three independent events happen one after the other, a list of the sample space tools cannot be used.
correct option: A list
What is an independent events?If the likelihood of the occurrence of one event has no bearing on the likelihood of the other, then the two occurrences are independent. The likelihood that both events A and B will occur is defined mathematically as being equal to the product of the probabilities of A and B. This is how independent occurrences A and B are expressed mathematically.
Thus, if three independent events happen one after the other, a list of the sample space tools cannot be used.
correct option: A list

An angle measures 12°. Find its complement. Do not include units in your answer.
Answer:
78
Step-by-step explanation:
complements = 90
x + 12 = 90
-12. -12
× = 78
If two angles are complementary,
then the sum of their measures is 90 degrees.
If two numbers add to 90, we can represent those numbers as x and 90 - x.
So we will call one of our angles x and its complement as 90 - x.
So we have 90 - 12 which is 78.
So the complement of a 12° angle is a 78° angle.

A store pays $365.84 for a fountain. The store marks up the price by 10%.
What is the amount of the mark-up?
Round your answer to the nearest cent: $
Answer:
The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.
Step-by-step explanation:
Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:
365.84 x 10/100 = X
3,658.4 / 100 = X
36,584 = X
36.584 + 365.84 = 402.424
Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

The original price of the Kindle is $269.99.
If the Kindle was 15% off, what is the discounted price of the Kindle?
Answer:
229.4915
Step-by-step explanation:
you first find 15% of $269.99 which is 15/100 * 269.99
which is 40.4915
and since you are finding the discounted price
you subtract 40.4915 from 269.99
= 269.99-40.4915
=229.4915
dont forget to put the unit ($)
=$229.4915

Mumuni Bawumia, a farmer sells 500 litres of fresh milk a day with a standard deviation of 35 litres. Given that the daily sales of fresh milk is normally distributed, what is the probability that the sales in any single day is:
a. Greater than 506 litres
b. Between 498 litres and 506 litres.
Answer:
a: 0.43194
b: 0.09084
Step-by-step explanation:
First construct the z values for 498 and 506.
[tex]z=\frac{x-u}{s}[/tex]
[tex]z(498)=\frac{498-500}{35}[/tex]=-0.05714
z(506)=(506-500)/35=0.17143
Check the cumulative normal distribution tables to find
P(x<=-0.05714)=0.47722
P(x<=506)=0.52278
These probabilities imply that
P(x>506)=1-P(x<=506)=1-0.52278=0.43194
P(498<=x<=506)=P(x<=506)-P(x<=498)=0.09084
