Answer:
6 ounces
Step-by-step explanation:
So set your equation up as
12(x)+20(6)=16(x+6)
You set it up this way because with the first number you know the percet but not the ounces so your ounces would be x. The second set you know percet and ounces (the percent will alway go outside the parenthesis). then the last number is waht it wil equal; again we know the percent but not the product. We put x+6 in the parenthesis because you are adding the ounces your don't know(x) wiht the ones you do (6).
To solve distribute
12x+120=16x+96
Now all you have to do is solve for x. Subtract the 96 over then subtract the 12x over, so it would look like this.
12x+120=16x+96
-96 -96
12x+24=16x
-12x -12x
24=4x Now simply divide by 4 and you get 6=x
There should be 6 ounces mixed in order to get the required solution.
Let the number of ounces be represented by x.
Based on the equation, the equation to use will be:
12(x) + 20(6) = 16(x + 6)
Expand the equation
12x + 120 = 16x + 96
Collect like terms
16x - 12x = 120 - 96
4x = 24
Divide both side by 4
4x/4 = 24/4
x = 6
Therefore, the number of ounces will be 6 ounces.

What is the surface area of a cylinder use 3.14 instead of pi button on your calculator the radius two the height is eight.
Please help and if any of you do ixl please let me know I need help with Lot of them !!
Answer:
125.60
Step-by-step explanation:
the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).

Namarachi earns a base pay of $2,200 per month. She also earns commission of 4% of her total sales. One month Namarachi earned $2,400. Explain how to find Namarachi’s total sales for that month. How much were her total sales?
Answer:
$5000
Step-by-step explanation:
To get the amount earned as commission, we deduct the fixed pay from the total earned pay. Given the total monthly earnings as $2400 while fixed pay of $2200, in this case, the amount of commission will be
Commission= 2400-2200=200
Since the commission is 4% of the total sales, then the total sales equivalent to 100% is given by cross multiplication
If4%=$200
100%=?
Total sales will be 100%*$200/4%=$5000

Answer:
Mean = 272.3
sd = 37.7
Step-by-step explanation:
Mean = sum/n
(221+248+251+255+259+263+264+272+291+297+374) ÷ 11
= 2995/11
= 272.2727273
Variance = (sum of x²)/n - mean²
[(221²+248²+251²+255²+259²+263²+264²+272²+291²+297²+374²)/11] - (2740/11)²
= (831067/11) - (2995/11)²

Q3. Express 984. 6080 correct to
a. 2 decimal places _______________
b. 4 significant figures _____________
c. 3 decimal places ________________
d. the nearest hundredth___________ help
Answer:
a) 984.6080 = 984.61 to 2 decimal places
b) 984.6080 = 984.6 to 4 significant figures
c) 984.6080 = 984.608 to 3 decimal places
d) 984.6080 = 984.61 to the nearest hundredth
Step-by-step explanation:
Answers to the approximation questions above are supplied below.
First, you needs to know approximation processes:
Step 1: Keep the required number of digits in question.
Step 2: Before rounding off the remaining digits, look at the next digit to the required number of accuracy, if it is 5 or more, increase the last digit of the number you're keeping by 1, otherwise leave it as it is and round down to zero all the unwanted digits.
Similarly, there is need know the meaning of each degree of accuracy.
1. Decimal places: These are the number of digits occurring after the decimal point. E.g. a set of figures in 1 decimal place has only one digit after decimal point, i.e. 65.4. In the case of the question above,
a) 984.6080 = 984.61 to 2 decimal places
c) 984.6080 = 984.608 to 3 decimal places
2. Significant figures: Basically, these are nonzero digits in a set of figures. However, when zero is in the middle of nonzero digits, i.e, 3045, such zero is a significant figure. In the question above,
b) 984.6080 = 984.6 to 4 significant figures
3. Hundredth: Under place value system, hundredth of a set of figures is located at two digits after the decimal point. In other words, hundredth is same as two decimal places so the same approach is required for the two. Thus;
d) 984.6080 = 984.61 to the nearest hundredth
You can see that the result for both 2 decimal places and nearest hundredth are the same, that is, 984.6080 = 984.61 to 2 decimal places and to the nearest hundredth respectively.
Therefore, the answers are summarized thus:
a) 984.6080 = 984.61 to 2 decimal places
b) 984.6080 = 984.6 to 4 significant figures
c) 984.6080 = 984.608 to 3 decimal places
d) 984.6080 = 984.61 to the nearest hundredth
Answer:
984.6080
a. 2 decimal places
984.61
b. 4 significant figures
984.6
c. 3 decimal places
984.608
d. the nearest hundredth

A rectangular stained glass window is made up of identical triangular parts as pictured below.
36 inches
48 inches
What is the area of the shaded triangular section?
18 square inches
36 square inches
72 square inches
144 square inches
Answer:
The area of the shaded triangular section is 72 square inches
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The rectangular stained glass can be divided into 24 identical triangular parts
step 1
Determine the area of complete rectangle
[tex]A=(48)(36)=1,728\ in^2[/tex]
step 2
Divide the area of complete rectangle by 24
[tex]1,728/24=72\ in^2[/tex]
therefore
The area of the shaded triangular section is 72 square inches
Answer:
72 square inches
Step-by-step explanation:
The image is shown below.
The area of a rectangle is length times width.
Length is 48 and width is 36
Hence, area of whole rectangle is:
Area = 48 * 36 = 1728
Now, the whole figure is broken down into
24 congruent triangles
So, each triangle's area is:
1728/24 = 72 square inches
The shaded region is ONE of the triangles, so the shaded region area is:
72 square inches

A table of values of a linear function is shown below.
Find the slope and y-intercept of the function's graph, and find the equation for the function.
Given:
A table of values of a linear function.
To find:
The slope, y-intercept and equation of the function.
Solution:
Take any two points on the table.
Let the points are (-1, -3) and (0, -6).
Slope of the line:
[tex]$m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]$m=\frac{-6-(-3)}{0-(-1)}[/tex]
[tex]$m=\frac{-6+3}{0+1}[/tex]
[tex]$m=\frac{-3}{1}[/tex]
m = -3
Slope of the function = -3
y-intercept of the function is the point where x = 0.
In the table y = -6 when x = 0
y-intercept = -6
Equation of a line:
y = mx + c
where m is the slope and c is the y-intercept
y = -3x + (-6)
y = -3x - 6
Equation of a function is y = -3x - 6.
The slope of the function's graph is 3, the y-intercept is 2, and the equation for the function is y = 3x + 2.
Explanation:To find the slope of the function's graph, we can use the formula: slope = (change in y) / (change in x). We can choose any two points from the table and calculate the slope. Let's choose the points (0,2) and (1,5). The change in y is 5 - 2 = 3, and the change in x is 1 - 0 = 1. Therefore, the slope is 3/1 = 3.
To find the y-intercept of the function's graph, we can use one of the points from the table. Let's use the point (0,2). Since the y-intercept is the value of y when x = 0, the y-intercept is 2.
The equation for a linear function is y = mx + b, where m is the slope and b is the y-intercept. So for this function, the equation is y = 3x + 2.

whats the least common denominator of 2/5 1/2 and 3/4?
Answer:
20
Step-by-step explanation:
Final answer:
The least common denominator for the fractions 2/5, 1/2, and 3/4 is 20, as it is the smallest number that all denominators can divide into without leaving a remainder.
Explanation:
The least common denominator (LCD) of the fractions 2/5, 1/2, and 3/4 is the smallest number that can be divided evenly by each of the denominators (5, 2, and 4, respectively). To find the LCD, we can list out the multiples of each denominator until we find a common multiple.
The multiples of 5 are 5, 10, 15, 20, 25, and so on. The multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. When we look at these lists, the smallest number that appears in all three lists is 20. Therefore, 20 is the least common denominator for the fractions 2/5, 1/2, and 3/4.

\angle C=180^{\circ}-131^{\circ}=49^{\circ}
The measure of angle C is 49°.
Sine formula:
\frac{a}{\sin a}=\frac{b}{\sin b}=\frac{c}{\sin c}
Using sine formula in triangle ABC, we get
\frac{AC}{\sin B}=\frac{AB}{\sin C}
\frac{AC}{\sin 33^{\circ}}=\frac{100}{\sin 49^{\circ}}
AC=\frac{100}{\sin 49^{\circ}}\times \sin 33^{\circ}
AC=\frac{100}{0.7547}\cdot0.544639
AC=72.166
AC\approx 72
Therefore the distance across the river from Omkar to the big rock is 72 meters.
