What is the area of this square?
A= 12
B= 48
C= 72
D= 144
No links, docs, files, drives etc
I will mark the correct answer brainlyest
You earn many points
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.
---------
Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
B
If you do 4x12 you will end up with 48
In Jan's library, she has 24 informational books. If 15% of the books are informational text, how many total books are in her library?
Answer:
160 books
Step-by-step explanation:
To find the total amount of something, when given the percent and how much value the percent is, use this
[tex]Total = \frac{Number*100}{Percent}[/tex]
This way we get:

Using the picture, find the measure of arc GR. (GK is the diameter)
Answer:
48°
Step-by-step explanation:
Given that GK is the diameter of the circle ;
Then GK which is the half of the circle is 360/2 = 180 (Angle at a Point = 360°)
Diameter =half of the entire circle = 360 /2 = 180
GK = 180°
GK =GR + KR = 180
KR = 132°
180 = GR + 132
GR = 180 - 132
GR = 48°

In 2004, a survey on computer crime indicated that 7% of reported unauthorized uses of business Web sites came from inside the company. In a survey taken two years later, it was found that 7 of a sample of 163 reported unauthorized uses of business Web sites came from inside the company. a) Conduct an appropriate hypothesis test to check if the proportion of reported unauthorized uses of business Web sites that came from inside the company has changed since 2004. Use the significance level of 0.05. State your conclusion. (5 Points) b) Find the p-value of the test and confirm that the conclusion based on the p-value agrees with the conclusion in part (a). (2 Points)
Answer:
a) H0 : P = 0.07
Ha : P ≠ 0.07
b) p -value = 0.1770
Step-by-step explanation:
P = 7% = 0.07
x (result ) = 7 , n = 163
p = x / n = 7 / 163 = 0.043
a) Using a significance level ( ∝ ) of 0.05, estimate the appropriate hypothesis
H0 : P = 0.07
Ha : P ≠ 0.07
conduct a Z- test statistic
Z = ( p - P ) / [tex]\sqrt{\frac{P(1-P)}{n} }[/tex]
= ( 0.043 - 0.07 ) / [tex]\sqrt{\frac{P(1-P)}{n} }[/tex] = - 1.35
Critical value ( Z₀.₀₂₅ ) = ± 1.96
we fail to reject H0 given that | z | < Zcritical because there is not enough evidence to conclude that proportion change
b) Determine the p-value of the test
P-value = P ( | Z | > Z )
= 2 * P ( Z < -1.35 )
= 0.1770
The p-value ( 0.1770 ) > ∝ ( 0.05 ) hence we fail to reject H0 ( i.e. the conclusion agrees with part a above )

Figure abc is a triangle with a base of 22 inches if abc is dilated by a scale factor of 0.5 what will be the base of the figure
Answer:
11
Step-by-step explanation:
Scale factor 0.5 means 1/2
so multiply base length with scale factor
22×0.5 = 11
Based on the figure below, find the value of x.
Answer:
The value of x = 9.Step-by-step explanation:
The figure shown is represented as a right triangle, which means that the sum of the angles within should add up to 90°. So if we take 32° (one of the angles given) and subtract it from 90°, we should be left with 58°.
This means that the value of the equation that contains "x" must equal 58°. Therefore, (6 x 9 + 4)° must equal 58.° Which means that the value of x = 9.
3x + 5y = 7;( -1 , 2) write an eqautian thats perpidicaluar to the given line that passes through the given point
Answer:
5x -3y + 11 = 0 .
Step-by-step explanation:
Firstly let's find the slope of the line by converting the equation into slope intercept form as ,
=> 3x +5y = 7
=> 5y = 7 - 3x
=> y = (7-3x)/5
=> y = -3/5x + 7/5
On comparing this equation to the slope intercept form y = mx + c ,=> m = -⅗
Now the slope of the line perpendicular to this line will be , say m'
=> m' =- 1/m
=> m' = -1/-⅗
=> m = 5/3
Now the line passes through (-1,2 ) . so on using point slope form , we get ,=> ( x - x1) m = ( y - y1)
=> ( x - (-1)) × 5/3 = y - 2
=> ( x +1)×5 = 3( y -2)
=> 5x + 5 = 3y -6
=> 5x - 3y +5 +6=0
=> 5x -3y +11 = 0
• Hence the equation of line perpendicular to the given line is 5x -3y + 11 = 0 .HELP JIMTHOMPSON5910
I'll do the first three problems (numbers 15 through 17) to get you started.
===================================================
Problem 15
Answer: 21.98--------------------
Explanation:
We cut the diameter in half to get the radius. We can think of cutting the 14 in half to get 7, ignoring the pi while we cut in half. Then after we do that, we tack the pi back on.
In short, 14pi cuts in half to 7pi.
Then we could see that 7*pi = 7*3.14 = 21.98
The radius is about 21.98 inches.
===================================================
Problem 16
Answer: 78.5--------------------
Explanation:
We'll plug r = 5 into the area of a circle formula.
A = pi*r^2
A = 3.14*5^2
A = 78.5 square yards approximately
===================================================
Problem 17
Answer: 6--------------------
Explanation:
We'll use the formula
C = pi*d
which is the formula that ties together the circumference C with the diameter d.
Plug in the given circumference C = 12pi and isolate d
C = pi*d
12pi = pi*d
12 = d .... divided both sides by pi, which cancels out
d = 12
The diameter is 12. Your step by step picture doesn't have to be this wordy, but I'm doing this to help show that the circumference like 12pi simply has the "pi" part erased to get the diameter. This allows a reader to quickly spot the diameter if given the circumference in this form. And it also allows to go from the diameter to the exact circumference without any calculator involved.
Once you get the diameter, you cut it in half to get the radius. Half of 12 is 6, so the radius is 6 cm.
------------
You could also have this as your steps
C = 2*pi*r
12pi = 2*pi*r
12 = 2r
2r = 12
r = 12/2
r = 6
which is an alternative way to see that the radius is 6 cm.

Pleaseeee helpppppppp!!!
Answer:
x = 46°
Step-by-step explanation:
Appling the principle of supplementary angle in Geomentry.
Supplementary angle: These are angles that sum up to 180°
From the diagram above, x and 134° are supplementry because they sum up to 180°.
Therefore,
134+x = 180 (Supplementary angle)
Solve for x
x = 180-134
x = 46°
Therefore, the value of the missing angle is 46°
900% of what number is 7,470
Answer:
830
Step-by-step explanation:
7470/9 = 830
Answer:
900% of 7470=67230
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 7470 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 7470 is 100%, so we can write it down as 7470=100%.
4. We know, that x is 900% of the output value, so we can write it down as x=900%.
5. Now we have two simple equations:
1) 7470=100%
2) x=900%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
7470/x=100%/900%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 900% of 7470
7470/x=100/900
(7470/x)*x=(100/900)*x - we multiply both sides of the equation by x
7470=0.11111111111111*x - we divide both sides of the equation by (0.11111111111111) to get x
7470/0.11111111111111=x
67230=x
x=67230
now we have:
900% of 7470=67230

Triangle Trigonometry)
look at picture
The height of the balloon above the ground is 554 ft.
I have attached a diagram where i have divided the triangle shown into 2.From the attached image, the third angle in triangle 1 would be;
180 - (90 + 85) = 5°
The supplementary angle in triangle 2 to 85° in triangle 1 is;
180 - 85 = 95°(because supplementary angles add up to 180)
The third angle of triangle 2 is; 180 - (95 + 75) = 10°
If we label the shared slant side between the two triangles as z, the we can use sine rule to find z from triangle 2;100/sin10 = z/sin 75
z = 100(sin 75)/(sin 10)
Applying trigonometric ratio to triangle 1, we can find h as;h/z = sin 85
h = z sin 85
h = [100(sin 75)/(sin 10)] × sin 85
h ≈ 554 ft

The average amount of ozone in several cities across Pennsylvania was found in a study to correlate with the average number of asthma cases in those cities. What type of study was this
Answer:
Ecological study
Step-by-step explanation:
When the basis for the conclusion of a study is done an a group or population level rather than on a person, single or individual basis, then we refer to this as an ecological study. In the scenario described above, relationship between ozone in Pennsylvania and the number of asthma cases was generalized and presented on the mean or average level rather than being compared in terms of individual figure. Hence, research studies of this type or nature are classed as ecological study.
