82.36
Step-by-step explanation:
284 x 0.29 = 82.36
Have an amazing day!
PLEASE RATE!
Answer:
Step-by-step explanation:
Alright, so the answer is $400. So we know that $284 is a discount on the whole price, 29% off. So 284 is 71% of the whole price, 100%-29%=71%. So then I just divided 284 by 71 and got 4. 284/71=4. Because I divided it by 71, $4 is 1% of the whole price, so I multiplied 4 by 100 and got $400 as the original price. You can just do this equation with any type of calculator, also please select my answer as the brainliest.✌

What is the best estimate for this sum?
1/4+2/7
The sum will be close to 1/4.
The sum will be close to 1/2.
The sum will be close to 1.
Answers
Answer:
The sum is close to 1/2
Step-by-step explanation:
1/4 = 7/28
2/7 = 8/28
7/28 + 8/28 = 15/28
14/28 = 1/2 and 15/28 is close to 14/28
This is because because if we make the expression into a decimal it would be 0.53571428.. and many other numbers. If you make 1/4 into a decimal it will be 0.25 which is not close to the other number. Where-as if we made 1/2 into a decimal it would be 0.5 which would be the closest. Hope this helps

16.2 is what percent of 90?
18%
14.6%
90%
16%
Answers
Answer:
18%
Step-by-step explanation:
Step 1: We make the assumption that 90 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100%=90
Step 4: In the same vein, x%=16.2
Step 5: This gives us a pair of simple equations:
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
Step 7: Taking the inverse (or reciprocal) of both sides yields
Therefore, 16.2 is 18% of 90
Answer:
16%
Step-by-step explanation: If its 16.2 out of 90 its %16 bc the .2 is not more than 5

7(x-2)=91
distribute the 7 by multiplying both x and -2 by it
7x-14=91
add 14 to both sides
7x=105
divide both sides by 7
x=15
Mauricio's Work:
7(x-2)=91
to get rid of the 7 multiplication, divide both sides by 7

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Range : 21
Interquartile range : 99.5 - 89 = 10.5
Did not study : 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91
Range : 46
Interquartile range : 89 - 65 = 24
Part B
The students that claimed to study had a lower range and interquartile than the students that did not study. Range difference between the students that did not study vs the students that did study, 46 > 21. Interquartile range difference between the students that did not study vs the students that did, 24 > 10.5.

The length of two sides of triangle are 4cm and 5cm. Between what two
measures should the length of the third side fall?
Answers
Answer:
1 and 9
Step-by-step explanation:
By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.
In other words, in a triangle with side lengths [tex]a, b,[/tex] and [tex]c,[/tex] we always have [tex]a+b > c.[/tex]
Applying this to this question, the other side length, [tex]x,[/tex] must satisfy the following inequalities:
[tex]4+5 > x,\\x+5 > 4,\\x+4 > 5.[/tex]
Solving these inequalities gives
[tex]x < 9,\\x > -1,\\x > 1.[/tex]
Combining these solutions, we have [tex]1 < x < 9.[/tex] Therefore, the length of the third side falls between 1 and 9.
