Answer:
a 10.21
Step-by-step explanation:
because 20 - 9.79 = 10.21
Answer:
the ans in the third one,
10.21, it shows the change
Step-by-step explanation:
20.00=c+9.79
so Pablo has 20.00 and he has to use 9.79
so if u add the change and the money he has to use, will be the money he has right now
so c = the change
so...
20.00=c+9.79
20.00-9.79=c
(so if u subtract the amount of money pablo has to pay from the money he has will be the change he will get)
10.21=c
Esmeralda draws a scale drawing of a rectangular community garden she helps manage. The scale factor from the drawing to the garden is 20. Based on the measurements of Esmeralda's drawing, what is the perimeter of the community garden?
Answer:
20
Step-by-step explanation:
The perimeter of the community garden is 130 unit.
What is Scale Factor?A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.
Given:
Scale factor = 20
After Scale factor the Dimension are
l = 2 1/4 x 20 = 9/4 x 20
l = 45
and, w = 1 x 20 = 20
So, Perimeter of rectangular Garden = 2( l +w)
= 2 ( 45+20)
= 2 ( 65)
= 130 unit.
Hence, the Perimeter is 130 unit.

Step-by-step explanation:
point D = -6
point A = 18
distance between point D and A: 18 - (-6) = 24
midpoint distance = 24/2 = 12 units away from each point
-6 + 12 = 6
18 - 12 = 6
your midpoint is at 6
Answer:

Steps to solve:

~Distribute right side
y - 5 = 3y - 9
~Add 5 to both sides
y = 3y - 4
~Subtract 3y to both sides

A weather balloon ascended from an elevation of 18 feet below sea level to an elevation 19 1/2 feet above sea level. What distance dd the weather balloon rise?
Answer:
The ballon rose a distance of 37 1/2 feet
Step-by-step explanation:
Here, we are interested in calculating the level of ascent of the weather balloon.
From the question, we are told that the ballon made a transition from below the sea to above the sea.
Now to calculate the total distance, we shall
be adding the distances below the sea and the distances above;
Mathematically, that would be;
18 feet + 19 1/2 feet = 37 1/2 feet
Max bought two items that were both on sale one item was 10% off and one item was 20% off max says that he saved 15% althogether is he correct?
Answer:
yes
Step-by-step explanation:
No, Max was wrong about his claim. Max saved 30% altogether.
Let the first item be (a) Let the second item be (b)Discount Offer
a = 10%b = 20%For the two items, the total discount that Max saved was
= (10 + 20)%
= 30%.
Averagely, if we are to determine the average discount for each of the items, we have:
= 30% ÷ 2
= 15%
So, on each item, Max saved 15% on average.
Therefore, we can conclude that Max saved 30% altogether for the two items.

Suppose the volume of a rectangular shopping cart basket is 12,090 cubic inches. If the length measures 31 inches and the width measures 19.5 inches, how high is the shopping cart basket?
Answer:
[tex]\boxed {\tt h=20\ inches}[/tex]
Step-by-step explanation:
The volume of a rectangular prism can be found using the following formula.
[tex]v=l*w*h[/tex]
We know that the volume is 12,090 cubic inches, the length is 31 inches, and the width is 19.5 inches.
[tex]v= 12,090 \ in^3\\l=31 \ in \\ w=19.5 \ in[/tex]
[tex]12,090 \ in^3= 31 \ in * 19.5 \ in * h[/tex]
Multiply 31 inches and 19.5 inches.
[tex]12,090 \ in^3= 604.5 \ in^2 * h[/tex]
We are trying to find h, therefore we must isolate it. h is being multiplied by 604.5 square inches. The inverse of multiplication is division. Divide both sides of the equation by 604.5 in²
[tex]\frac{12,090 \ in^3}{604.5 \ in^2}= \frac{604.5 \ in^2 *h}{604.5 \ in^2}[/tex]
[tex]\frac{12,090 \ in^3}{604.5 \ in^2}=h[/tex]
[tex]20 \ in =h[/tex]
The height of the shopping basket is 20 inches.

What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.
Variable: A symbol without a set value is referred to as a variable.
Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.
Given:
Each ride cost $2.
Each game cost $2.
Andrew went on 3 rides and played g games.
So, the ride costs = $6
and, games costs = $2g
Andrew pay in total = 6 + 2g
= 2 (3 + g)
Hence, the expression can also be 2(3 + g).

Mike and Teegan each measured the volume of the 16-ounce bottle three times. They recorded their measurements as shown. Mike: 16.4 oz, 15.2 oz, 15.8 oz Teegan: 16.34 oz, 16.59 oz, 15.13 oz Which statement is true? Mike's measurements are more precise and more accurate. Teegan's measurements are more precise and more accurate. Mike's measurements are more precise, but Teegan's measurements are more accurate. Mike's measurements are more accurate, but Teegan's measurements are more precise.
Answer:
The correct option is;
Mike's measurement are more precise and more accurate
Step-by-step explanation:
The given information are;
The mass of the measured bottle = 16-ounce
The record of the measurements made by Mike are;
16.4 oz
15.2 oz
15.8 oz
The record of the measurements made by Teegan are;
16.34 oz
16.59 oz
15.13 oz
From the two measurements, we have;
The precision of a measurement depends on how close the values of the measurement are to one another, therefore, we have;
For Mike, the precision is given as follows
16.4 - 15.2 = 1.2
16.4 - 15.8 = 0.6
15.8 - 15.2 = 0.6
Total difference = 1.2 + 0.6 + 0.6 = 2.4
For Teegan , the precision is given as follows
16.59 - 16.34 = 0.25
16.59 - 15.13 = 1.46
16.34 - 15.13 = 1.21
Total difference = 0.25 + 1.46 + 1.21 = 2.92
Therefore, Mike's measurements are more precise than Teegan's measurements
The accuracy of the measurement is the amount of closeness the measurements are to a given value
In the question, the given value is 16-ounces of the volume of the bottle
Therefore, by the mean absolute deviation from the 16-ounce of the bottle, we have;
For Mike;
[tex]Mean \ absolute \ deviation = \dfrac{\left | 16.4 - 16 \right | + \left | 15.2 - 16 \right | + \left | 15.8 - 16 \right | }{3} = 0.533[/tex]
For Teegan, we have;
[tex]Mean \ absolute \ deviation = \dfrac{\left | 16.34 - 16 \right | + \left | 16.59 - 16 \right | + \left | 15.13 - 16 \right | }{3} = 0.6[/tex]
Therefore, Mike's measurement is more accurate than Teegan's measurement.
Which gives;
Mike's measurement are more precise and more accurate.
Answer:
Mike’s measurements are more accurate, but Teegan’s measurements are more precise.

Ms.Samuel has taken a survey of college students and found that 1 out of 7 students are liberal arts majors. If a college has 12,000 students, what is the best estimate of the number of students who are liberal arts majors
Answer:
1714 studentsStep-by-step explanation:
If 1 out of 7 students are liberal arts majors based on Ms. samuel survey, the estimate of the number of students who are liberal arts majors if the total number of student in the college s 12,000 can be gotten using the equality expression.
7 students = 1 liberal art major student
12,000 = x liberal art major students
cross multiply
7*x = 12000*1
7x = 12000
divide both sides by 7
7x/7 = 12000/7
x = 1714.29
x≈ 1714
Hence the best estimate for the number of students who are liberal arts majors is 1714 students.
