help guys plsss need na now .,.
Answer:
-1/60
Step-by-step explanation:
9/20-7/15=27/60-28/60
=-1/60
Answer:
-1/60
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(9/20, 7/15) = 60
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(9/20×33)−(7/15×44)
Complete the multiplication and the equation becomes
27/60−28/60
The two fractions now have like denominators so you can subtract the numerators.
Then:
27−28/60=−1/60
This fraction cannot be reduced.
Therefore:
9/20−7/15=−1/60

A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing 12$ is displayed by the store manager at a selling price of 8$. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
please help me in really stuck you would be a huge help
Answer:
Step-by-step explanation:
12$ = original price (need to add 67% mark up)
12/100 = 0.12 = 1%
0.12 x 67 = $8.04 markup
12 + 8.04 = $20.04 is the correct selling price
the error was accidently not adding the markup ($8.04) to the original price

What is the approximate solution to the equation 2^t=22?
0.6712
1.0414
4.4594
11.0000
Answer:
[tex]t=4.4594[/tex]
Step-by-step explanation:
We can take the log 2 of both sides to get [tex]t=\log_2(22)[/tex].
We know that [tex]2^4<22<2^5[/tex], so [tex]4<t<5[/tex].
So, the solution is [tex]\boxed{t=4.4594}[/tex] because it's the only answer that works.

Answer:
hi robertlyonsdamron the answer will be B
Step-by-step explanation:
You can use the order of operations to evaluate the expression. Perform the subtraction inside the parentheses: two minus three equals negative one. Evaluate the exponents: two to the sixth power is sixty-four. Multiply and divide in order from left to right: Twelve point six times negative one equals negative twelve point six, and sixty-four divided by four is sixteen. Add and subtract in order from left to right: Negative twelve point six plus sixteen equals three point four.
Find the new amount after increasing $30 by 15%. I need help it’s due soon! Thanks!
Answer:
$34.5
Step-by-step explanation:
15% of $30 is 4.5
So 30+4.5=34.5
15 / 100 × 30 = 4.5
30 + 4.5 = 34.5
The answer is 34.5

Could a triangle have angle measures of 94°, 106°, and 11° EXPLAIN HOW YOU KNOW.
Answer:
Nope
Step-by-step explanation:
All angles have to measure up to where adding up two of any angles will result in a number greater than or equal to the angle that was not added.
But here if we add up 94° and 11°, we end up with 105°.
Since 105° is lower than the angle not added, which is 106°, this triangle cannot exist.

find median :
the hight of 10 students are given ➡ 155,160,145,149,150,147,152,184,144,148.
Here let's use python to find our median.(Console attached)
Spare way:-
Let's use statistics
Here n is even[tex]\\ \sf\longmapsto Median=\dfrac{n}{2}+\dfrac{n+1}{2}[/tex]
[tex]\\ \sf\longmapsto Median=\dfrac{10}{2}+\dfrac{10+1}{2}[/tex]
[tex]\\ \sf\longmapsto Median=5th+6th/2[/tex]
Order from largest to smallest
184,160,155,152,150,149,148,147,145,144[tex]\\ \sf\longmapsto Median=\dfrac{150+149}{2}[/tex]

Seventeen lines drawn in a plane, with no three concurrent and no two parallel, divide the plane into
closed regions (bounded on all sides) and open regions. The number of closed regions is
Answer:
120
Step-by-step explanation:
Make a chart:
Lines: 0 1 2 3 4 5 6
Closed regions: 0 0 0 1 3 6 10
Find the number of numbers using the formula:
[tex]\frac{first term + last term}{2}[/tex] x 14 = [tex]\frac{2 + 15}{2}[/tex] x 14
= 8.5 x 14
= 119
119 + 1 = 120
(add 1 because we didn't count the first line in the formula)
I hope this helps :)
The total number of closed regions is 120.
Given that,
Seventeen lines are drawn in a plane, with no three concurrent and no two parallel, dividing the plane into closed regions (bounded on all sides) and open regions.
Used the formula to calculate the number of closed regions with n sides is,
Number of sides = (n - 1) (n - 2) / 2
Here, n = 17
Hence, The number of closed regions is,
Number of sides = (n - 1) (n - 2) / 2
Number of sides = (17 - 1) (17 - 2) / 2
Number of sides = 16 × 15 / 2
Number of sides = 120
