Answer:
x = [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Given
- 3 - 39x = 11x - 23 ( subtract 11x from both sides )
- 3 - 50x = - 23 ( add 3 to both sides )
- 50x = - 20 ( divide both sides by - 50 )
x = [tex]\frac{-20}{-50}[/tex] = [tex]\frac{2}{5}[/tex]
A whippet runs 50 feet in one second. An ostrich can run at 40 mph. A giraffe runs half a mile in a minute. A domestic cat scurries 15 yards in one second. Which animal is fastest?
Answer:
Step-by-step explanation:
You need to translate these into a common rate.
feet / second is probably the best one.
Whippet: 50/1 = 50 feet / second.
Ostrich: 40 miles/ hour = 40 *[ 1 hour/3600 sec] * [5280 feet / mile] = 58.67 ft/sec
Giraffe: 1/2 mile / minute * [1 minute/60 sec]*[5280 feet/mile] = 1/2 * 5280/60 = 44 feet/second
Cat: 15 yards / sec [ 3 feet/ yard] = 45 feet / second
Looks like the Ostrich is the fastest.
Please help and hurry please thank you!

In an inventory of 100 sodas, 65 are
diet and 30 are caffeine-free. Of the
diet sodas, 22 are caffeine-free. If a
soda in the inventory is selected at
random, what is the probability that it
is neither diet nor caffeine-free?
Answer:
5% I think
Step-by-step explanation:
Its mostly just a guess but I think its 5%
The probability that it is neither diet nor caffeine-free is 0.13.
What is Probability?Probability is the likeliness of an event to happen.
The number of total sodas = 100
The number of diet soda = 65
The number of Caffeine free sodas = 30
The number of caffeine free sodas out of diet sodas = 22
The number of soda that are neither caffeine nor soda is 100 -65-22 = 13
The probability that it is neither diet nor caffeine-free is 13/100 = 0.13

i need help with my math problem 8(−12)=
Answer:
The answer is -96
Step-by-step explanation:
First, you need to think of the question as a normal multiplication question. When there is a number in parenthesis next to a number with no symbol in between, that means multiplication. So multiply 8 with 12. This would equal 96. Since the sign of the greater number is negative, you would put a negative sign before the number 96, giving you the answer -96.
I hoped that helped! You are welcome! :)
What is the justification for step 2 in the solution process?
12 - X= 7x+32
Step 1: -X= 7x + 20

A rectangle has a length of 8.3cm and a permimeter of 22.4 cm. Enter the widty of the rectangle, in decimal form, in the box.
Answer:
the width is 2.9
Step-by-step explanation:the perimeter is found by L+W+L+W. Each L is going to be the same length and each width is going to be the same length since its a rectangle.
Double the length. 8.3+8.3= 16.6
Then subtract that from the perimeter. 22.4-16.6= 5.8
Then divide 5.8 as that is the total of the two missing sides. 5.8/2= 2.9
Then 2.9 is your answer. Hope that helps.
Find the distance between (-12, 1) and (12, -1) *
Answer:
[tex]d = 2\sqrt{145}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you determine the distance between the two following points ( [tex](-12, 1)[/tex] and [tex](12, -1)[/tex] ):
-Distance Formula:
[tex]d = \sqrt{(x_{2} - x_{1}) ^2 + (y_{2} - y_{1})^2}[/tex]
(where [tex]( x_{1}, y_{1})[/tex] represents the first point, and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the following points to the equation:
[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]
[tex]( x_{1}, y_{1})[/tex] = [tex](-12, 1)[/tex]
[tex](x_{2}, y_{2})[/tex] = [tex](12, -1)[/tex]
-Solve the equation:
[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]
[tex]d = \sqrt{(24)^2 + (-2)^2}[/tex]
[tex]d = \sqrt{576 + 4}[/tex]
[tex]d = \sqrt{580}[/tex]
[tex]d = 2\sqrt{145}[/tex]
Therefore, the distance is [tex]2\sqrt{145}[/tex].

The number N was increased by 20%, and then the result was again increased by 20% By what percent is the final result greater than the
original number?
E. 44%
F. 40%
G. 20%
H. 10%
Answer:
44%
Step-by-step explanation:
Suppose the original number is 100.
It is increased by 20 %, so the result will be 120.
The resulting number is again increased by 20%, which is increased by 120 *20/100, which is increased by 24. The final result will be 120+24 that is 144.
The final result is increased by 44 compared to the original number 100.
So, increase by 44%.

Change 20 5/9 to an
improper fraction.
Answer:
185/9
Step-by-step explanation:
20 5/9
Multiply 20 by the 9 (the denominator), and you''ll get 180.
Add the 5 (the numerator) to 180, and you'll get 185.
Then, place 185 over the denominator which is 9 and you get 185/9!
Answer:
[tex]\frac{185}{9}[/tex]
Step-by-step explanation:
This is the answer because:
1) The formula of changing mixed fractions to improper fractions is denominator times the whole number plus the numerator
2) Denominator = 9
Whole number = 20
Numerator = 5
9 x 20 + 5 = 185
Therefore, the answer is [tex]\frac{185}{9}[/tex]
Hope this helps!
