A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width was f the lake is 1,000 m, what is the width of the lake on the scale drawing?
Answer:
12,5 centimeters.
Step-by-step explanation:
We take the following proportion
[tex]\frac{1 cm}{80m} = \frac{x}{1000m}[/tex]
Which becomes:
[tex]1000 = 80x[/tex]
And then, we clear out the variable x:
[tex]\frac{1000}{80}=\frac{100}{8}=\frac{50}{4}=12,5[/tex]
And this means that the width of the lake on the scale drawing will be 12.5 cm.
Harper Hospital treated 423 patients last week who were children, out of a total of 931 patients. The administrator calculates that they had 408 adult patients. Is the administrator's calculation reasonable? Estimate the number of adult patients by rounding the numbers to check the administrator's calculation.
Answer:
No, the administrator is wrong.
[tex]Adult = 500[/tex]
Step-by-step explanation:
Given
[tex]Total = 931[/tex]
[tex]Children = 423[/tex]
[tex]Adult = 408[/tex]
Solving (a): Is the administrator correct?
No, the administrator is wrong.
This is so because: when the number of children is subtracted from the total patient, the remaining number is not 408
Solving (b): Estimate the number of adults
By rounding up:
[tex]Adult = Total - Children[/tex]
Actual Figures
[tex]Adult = 931 - 423[/tex]
Round up
[tex]Adult = 900 - 400[/tex]
[tex]Adult = 500[/tex] -- approximately

Miamor wanted to make note cards by cutting pieces of paper in half.
Before starting she got seven more pieces to use. When she was done she
had 28 half pieces of paper. With how many full pieces did she start?
Answer: 14 pieces
Step-by-step explanation:
Let the number of pieces of paper she had at first be x.
Before starting she got seven more pieces to use. This can be written as:
= x + 7
When she was done she had 28 half pieces of paper. This can then be written as:
x + 7 = (28 × 1/2)
x + 7 = 14
x = 14 - 7
x = 7
Since x = 7, she started with:
= x + 7
= 7 + 7
= 14 pieces
Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future.
Complete Question:
Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?
s(t)•h(t)= (3x-4)(2x-8)
= 6x² - 24x -8x - 32
= 6x² - 32x - 32
Answer:
Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.
Advice: Jamie should take note of the rule that applies when multiplying signs.
Step-by-step Explanation::
To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:
s(t)•h(t)= (3x-4)(2x-8)
Using distributive property, do the following:
[tex] 3x(2x - 8) -4(2x - 8) [/tex]
[tex] 3x*2x -3x*8 -4*2x -4*-8 [/tex]
[tex] 6x^2 - 24x - 8x + 32 [/tex] (this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)
Add like terms
[tex] 6x^2 - 32x + 32 [/tex]
Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.
Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.
Jackson invested 30% of what he earned last month if he invest 1200.00 how much did Jackson earn in total last month, in dollars
Answer:
$4000
Step-by-step explanation:
use formula a = w*p
1200.00 = w0.3
/ 0.3 /0.3
w = 4000
The total earnings done by Jackson last month will be equal to 4000.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information provided in the question,
Total investment is done by Jackson = 1200
The investment is 30% of total earnings.
Assume that Jackson's earnings are x.
Then,
30% of x = 1200
x = 1200 × (100/30)
x = 4000

Nadya's cell phone provider charges a monthly fee of $35 for usage up to 200 minutes. If she uses more than this in a month, she is charged $0.23 for each additional minute. Let c represent the cost of Nadya's bill if she uses m minutes of air time. Write an expression that can be used to find c if she used more than 200 minutes last month.
Answer:
c=35+0.23mStep-by-step explanation:
Given that Nadya's uses the service for up to 200 times then
let let c represent the cost of Nadya's bill
and m be the minutes of airtime
therefore
the initial charger is $35
The charge per additional minutes is $0.23
c=35+0.23m
Therefore the expression is
c=35+0.33m

Sydney's teacher says she may have her report card percentage based on either the mean or the median and she
can drop one test score if she chooses.
94%, 84%, 100%, 68%
Which measure of center should Sydney choose so she can have the highest percentage possible?
O Sydney should choose the mean after dropping one test score.
O Sydney should choose the mean without dropping one test score.
O Sydney should choose the median after dropping one test score.
O Sydney should choose the median without dropping one test score.
Next
Save and Exit
Submit
Mark this and return
Answer:
The correct answer is:
Sydney should choose the median after dropping one test score.
Step-by-step explanation:
when scores are not dropped:
List of scores = 68%, 84%, 94%, 100%
Mean = (68 + 84 + 94 + 100) ÷ 4 = 86.5%
Median = 68 84 94 100
Median = (84 + 94) ÷ 2 = 89%
Although there are no outliers because Sydney was given the option to drop a test score, dropping the lowest score will increase his overall chances of making a higher score. Therefore, 68% will be dropped.
List of scores when the lowest score is dropped = 94%, 84%, 100%
Mean: (84 + 94 + 100) ÷ 3 = 92.7%
Median: 84, 94, 100
Median = 94% (middle term)
From the four possible scores, the highest score is 94%, and it is gotten by finding the median after dropping a score
