6 / 10 = 60%
b) Count the shaded boxes: 11
Count the total: 20
11 / 20 = 55%
Answer:
Hey!
a) 60%
b) 55%
Step-by-step explanation:
how do you get a??
we have to c ount the shaded boxes: 6 boxes
6 divided by 10 = 0.6 (multiply by 100 to get 60%)
Now...
We have to count the shaded boxes: 11 boxes in total
Count the total available boxes: 20
11 divided by20 = 0.55 (multiply by 100 to get 55%)

Identify the sets as integers,natural numbers or whole numbers {0,5,10,15}
Answer: They are all of the above.
Step-by-step explanation: A integer is a whole number, a whole number is a integer and a natural number is a whole number. The definition of a whole number is a number with no fractions, the definition of a integer is a number with no fractions, and the definition of a natural number is a positive number.
The numerator of a rational number is less that it’s denominator by 7.If the new number becomes 3/2 when the numerator is tripled and the denominator is increased by 16, find the original number
Pls help me with this question
Answer:
[tex]\frac{23}{30}[/tex]
Step-by-step explanation:
let the denominator of the original fraction be x, then
[tex]\frac{x-7}{x}[/tex] ← is the original fraction
After the given changes, that is
[tex]\frac{3(x-7)}{x+16}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )
6(x - 7) = 3(x + 16) ← distribute parenthesis on both sides
6x - 42 = 3x + 48 ( subtract 3x from both sides )
3x - 42 = 48 ( add 42 to both sides )
3x = 90 ( divide both sides by 3 )
x = 30
Thus
[tex]\frac{30-7}{30}[/tex] = [tex]\frac{23}{30}[/tex] ← the original rational number

Aljan and Bella are both driving from Cleveland to Chicago. Aljan leaves at
7:40 and averages 60 mph (miles per hour on the way. Bella leaves at 8:00
and averages 65 mph on the way. The situation is modeled by this system,
where x is the number of hours after Bella leaves and y is the distance each
will travel:
y = 60x + 20
y = 65x
How long after Bella leaves will she pass Aljan, and how far will they each
have traveled?
Answer:
Bella will pass Ajjan after 4h and they will have travelled 260 miles.
Step-by-step explanation:
In order to calculate the number of hours, "x", that it'll take for Bella to pass Aljan, we need to find the value of "x" that makes both equations equal. Therefore,
[tex]60*x + 20 = 65*x\\65*x - 60*x = 20\\5*x = 20\\x = \frac{20}{5} = 4[/tex]
In order to calculate the distance they traveled, we must use this value for "x" in any of the equations, as done below:
[tex]y = 65*4\\y = 260[/tex]
Bella will pass Ajjan after 4h and they will have travelled 260 miles.
Answer:
Bella will pass Ajjan after 4h and they will have travelled 260 miles.

A rectangular street sign has an area of 40 square inches and a perimeter of 28 inches. What are the dimensions of the sign?
inches by inches
Answer: 4 inches by 10 inches
Step-by-step explanation:
The area of a rectangle can be written as b*h, while perimeter is equal to (2b +2h).
A = b*h = 40
P = 2b + 2h = 28
P = 2b + 2h
28 = 2b + 2h
28 = 2(b+h)
14 = b + h
What two numbers add to 14 and multiply to 40?
4 * 10 = 40
4 + 10 = 14

Answer:
The angle is 36.87°
Step-by-step explanation:
To find the missing angle, we will have to use inverse SOH-CAH-TOA.
Looking at the angle, as well as the two sides, we can infer that the opposite of the unknown angle is 24. Since the given side is not the hypotenuse but the adjacent, we know that we will be using inverse tangent (TOA).
[tex]tan^{1}[/tex] (x) = [tex]\frac{24}{32}[/tex]
x = [tex]tan^{-1}[/tex] ([tex]\frac{24}{32}[/tex])
x = 36.87°
Answer:
≈ 36.9
Step-by-step explanation:
You are given the opposite and adjacent side, leading you to use tan. However, since you're trying to find the angle measurement, and not the side, you use the inverse of tan: [tex]tan^-1[/tex]
Set it up like this:
[tex]tan^-1 (\frac{24}{32})=?[/tex]
When you solve, you get:
36.86
Round to the nearest tenth:
36.9

y=2x-3
-x-8y=7
Answer & Step-by-step explanation:
y = 2x - 3
-x - 8y = 7
Since, we have a equation for y, then we can substitute this equation for y to solve for x.
-x - 8(2x -3) = 7
-x - 16x + 24 = 7
-17x + 24 = 7
-17x = -17
x = 1
So, since we know that x is equal to 1, then we can plug in this number for the equation of y to find y.
y = 2(1) - 3
y = 2 - 3
y = -1
So, the solution is (1, -1). X equals 1 and y equals -1.

write a table to show your steps for calculating the standard deviation and then use your table to calculate the standard deviation of the values listed:
10, 11, 12, 10.5, 11.25, 12.25, 10
Answer:
The standard deviation for the given data set is 1.65.Step-by-step explanation:
The Standard Deviation is defined as
[tex]\sigma =\sqrt{\frac{\Sigma (x_{i} -\mu)^{2} }{N-1} }[/tex]
Where [tex]\sigma[/tex] is the standard deviation, [tex]\mu[/tex] is the mean and [tex]N[/tex] is the total number of data.
So, first, we need to find the mean of the data set.
[tex]\mu = \frac{10+11+12+10.5+11.25+12.25+10}{7} =11[/tex]
Now, we have to subtract each data with the mean to then elevate the differnece to the square power.
[tex]10-11 = -1 \implies (-1)^{2}=1\\ 11-11 = 0 \\12-11 = 1 \implies 1^{2}=1\\ 10.5-11 = -0.5 \implies (-0.5)^{2} =0.25\\11.25 - 11 = 0.25 \imples (1.25)^{2}=0.0625\\12.25 - 11 = 1.25 \implies (1.25)^{2}=1.5625\\10-11 = -1 \implies (-1)^{2}=1[/tex]
Then, we sum all these results.
[tex]\Sigma (x_{i}- \mu )^{2}=1+0+1+0.25+0.0625+1.5625+1=16.278[/tex]
Next, we divide the sum by [tex]N-1=7-1=6[/tex]
[tex]\frac{\Sigma (x_{i}-\mu )^{2} }{N-1}=\frac{16.278}{6} \approx 2.713[/tex]
Finally, we apply the square root.
[tex]\sigma = \sqrt{2.713} \approx 1.65[/tex]
Therefore, the standard deviation for the given data set is 1.65.

2) The sum of two numbers is 100. Their difference is 4. What are the two numbers?
Answer: 48, 52
Step-by-step explanation:
The sum of the two numbers (x, y) is 100. This means that;
x+y=100
Their difference is 4, so;
y=x+4
Now, you can substitute that in for y;
x+(x+4)=100
Simplify;
2x+4=100
2x=96
x=48
Now, we plug in the value of x to the second equation;
y=48+4
y=52
Answer:
48 and 52
Step-by-step explanation:
We have a pair of simultaneous equations and will solve these using substitution.
x + y = 100 (1)
x - y = 4 (2)
Solve for x:
x+y=100 , x - y = 4
x=52
Substitute x with 52
(52) + y = 100 , (52) - y = 4
Simplify:
y = 48

What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The slope of the linear function that is represented by the table,
Slope, m = [(-3/5) - (-13/30)]/[(2/3)-(1/4)]
= [(-18+13)/30] / [(8-3)/12]
= -(12/30)
= -(2/5)
The y-intercept of the linear function that is represented by the table can be found by substituting the coordinate of any one point in the equation of the line.
[tex]y = mx + c\\\\-(\dfrac{2}{15}) = -(\dfrac{2}{5})(-\dfrac12) + C\\\\-\dfrac{2}{15} = \dfrac15 + C\\C = -\dfrac5{15}\\\\C = -\dfrac13[/tex]
Hence, The slope is Negative two-fifths, and the y-intercept is Negative one-third. Hence, the correct option is A.
