Find the perimeter of the figure to the nearest hundredth.
Answer:
60.00 in^2
Step-by-step explanation:
First focus on the area ABOVE the dotted line. The shape here is that of a trapezoid. The two leg lengths are 12 in and 18 in (18 in is the diameter). At the far right of this trapezoid we can picture a triangle of base 3 in, height h and hypotenuse 5 in. Using the Pythagorean Theorem, we get h = 4 in.
This 4 in measurement is the width of the trapezoid. Thus, we are now ready to apply the formula for the area of a trapezoid: A = (average length of legs)*(width).
Here that area comes out to
12 in + 18 in
A = --------------------- * 4 in = 15 in*4in = 60 in^2, or (to the nearest hundredth)
2 60.00 in^2
The total area of the figure is 77 square centimeters. The overall height of the figure is 9 centimeters.
Drag the correct measurements to label the unknown lengths in the figure.
Answer:
5cm and 10 cm
Step-by-step explanation:
Since the overall height of the shape is 9 and the base of the triangle shaped piece is 6, the area of that piece is 6*9/2=27 units. Subtracting this from the total of 77, you know that the rectangle must have an area of 50 units. Out of the options that you have to drag, the only two that multiply together to be 50 units are 5 for the shorter side and 10 for the longer side. Hope this helps!
The correct measurements to label the unknown lengths in the figure 5 cm and 10cm.
What is Area of Rectangle?The area of Rectangle is length times of width.
The overall height of the shape is 9 cm
The base of the triangle shaped piece is 6
The area of triangle is 1/2×base×height
Area of that piece is 6×9/2=27 units.
Now let us subtract this from the total area
Total is 77 units
the rectangle must have an area of 50 units.
the only two that multiply together to be 50 units are 5 for the shorter side and 10 for the longer side.
Hence, the correct measurements to label the unknown lengths in the figure 5 cm and 10cm.

Milan will rent a car for a day. The rental company offers two pricing options: Option A and Option B. For each pricing option, cost (in dollars) depends on miles driven, as shown below.
(a) If Milan drives the rental car 150 miles, which option costs more?
Option A or Option B
How much more does it cost than the other option? __
(b) For what number of miles driven do the two options cost the same? __
If Milan drives less than this amount, which option costs less?
Option A or Option B
Answer:
If she drives the car 150 miles, option A costs more. It'll cost $30 more.
The options cost the same if she drives 75 miles. If she drives less than 75 miles, option A costs less.
The required answer for (a) if Milan drives car 150 miles then Option A costs more $30 than Option B
Also the answer for (b) is the two Options costs same at 150 miles

f(x)= 2x/x+1 use long division to rewrite
In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6997 subjects randomly selected from an online group involved with ears. There were 12961296 surveys returned. Use a 0.01 significance level to test the claim that the return rate is less than 20%. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.
Answer:
[tex]z=\frac{0.185 -0.2}{\sqrt{\frac{0.2(1-0.2)}{6997}}}=-3.137[/tex]
[tex]p_v =P(z<-3.137)=0.0009[/tex]
Since the p value is very low we have enough evidence to reject the null hypothesis at the significance lvel given of 0.01 so then we can conclude that the return rate ofr this case is significantly lower than 20%
Step-by-step explanation:
Data given
n=6997 represent the random sample taken
X=1296 represent the returned surveys
[tex]\hat p=\frac{1296}{6997}=0.185[/tex] estimated proportion of returned surveys
[tex]p_o=0.2[/tex] is the value that we want to test
z would represent the statistic (variable of interest)
[tex]p_v[/tex] represent the p value (variable of interest)
System of hypothesis
We need to conduct a hypothesis in order to test the claim that the true proportion of returned surveys is less than 0.2.:
Null hypothesis:[tex]p\geq 0.2[/tex]
Alternative hypothesis:[tex]p < 0.2[/tex]
The statistic is given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Calculate the statistic
Since we have all the info required we can replace in formula (1) like this:
[tex]z=\frac{0.185 -0.2}{\sqrt{\frac{0.2(1-0.2)}{6997}}}=-3.137[/tex]
Statistical decision
The next step would be calculate the p value for this test.
Since is a left tailed test the p value would be:
[tex]p_v =P(z<-3.137)=0.0009[/tex]
Since the p value is very low we have enough evidence to reject the null hypothesis at the significance lvel given of 0.01 so then we can conclude that the return rate ofr this case is significantly lower than 20%
We formulate a null and alternative hypothesis about the survey return rate. Then, given the returned survey and total survey counts, we calculate a sample proportion, standard deviation, and a z-score. Using this z-score, we compute a p-value, which is checked against the given significance level to make a decision about the hypothesis.
Explanation:In this scenario, we are interested in whether the cell phone survey return rate is less than 20%. So we can set our null hypothesis (H0) as: The return rate is 20% or more, and our alternative hypothesis (Ha) as: The return rate is less than 20%.
Given that 12961296 surveys were returned out of 6997, we can compute the sample proportion (p). Then, we calculate the standard deviation (sd) of the sampling distribution of the proportion (assuming H0 is true - i.e., the proportion in the population is 20%).
Using this sd and the sample proportion, we can calculate the z-score. The p-value would be the probability of getting a z-score as extreme as what we got, assuming H0 is true. If the p-value is less than the significance level (0.01), we would reject the null hypothesis. If it's higher, we fail to reject the null.
Note: Due to the likely typographical error in the given number of returned surveys, the precise computation cannot be done here.

A school is planning for an addition in some open space next to the current building. The existing building ends at the origin. The graph represents the system of equations that can be used to define the space for the addition. What is the system of equations that matches the graph? y ≤ 3x y > –2x – 1 y > 3x y ≤ –2x – 1 y < –3x y ≥ 2x – 1 y > –3x y ≤ 2x – 1
Answer:
y ≤ 3x and y > –2x – 1 (close answer)
Step-by-step explanation:
Line pass (-1 , -3) and (0 , 0)
slope = (0 - (-3)) / (0 - (-1)) = 3
y intercept = 0
y = 3x
Everything to the right of the line is shaded: (if include the line) y ≤ 3x
if not include the line and only everything to the right: y < 3x
Line pass (-2 , 3) and (1 , -3)
slope = (-3 - 3) / (1 - (-2)) = -2
y intercept = 3 - ((-2) x (-2)) = -1
y = -2x - 1
Everything to the right of the line is shaded: (if include the line) y ≥ -2x - 1
if not include the line and only everything to the right: y > -2x - 1
in all the options listed, only the first one y ≤ 3x and y > –2x – 1 close to the equation above. But y ≤ 3x must include the line y=3x (noy mentioned in the question above)

Given:
The number 12 is the geometric mean between 3 and a number x.
We need to determine the value of x.
Value of x:
Since, we know that the geometric mean is the square root of the product of two numbers.
Hence, we have;
[tex]Geometric \ mean= \sqrt{a \times b}[/tex]
where a and b are two positive numbers.
Substituting Geometric mean = 12, a = 3 and b = x, we get;
[tex]12= \sqrt{3 \times x}[/tex]
Squaring on both sides, we get;
[tex]12^2=3 \times x[/tex]
[tex]144=3\times x[/tex]
Dividing both sides of the equation by 3, we have;
[tex]48=x[/tex]
Thus, the value of x is 48.
What is the greatest common factor of 24s^3,12s^4,18s
Answer:
6s
Step-by-step explanation:
Answer:
6s

Final answer:
Given that △LMN is congruent to △PQR, the true congruency statements are QP≈ML, MN≈QR, ∠M≈∠Q, and ∠R≈∠N.
Explanation:
When two triangles are congruent, it means that they have the exact same size and shape, with corresponding sides and angles that are equal.
Given that △LMN≈△PQR, we can make the following true congruency statements:
QP≈ML: Since △LMN≈△PQR, side ML of △LMN must be congruent to side QP of △PQR.MN≈QR: Side MN of △LMN is congruent to side QR of △PQR, again due to the congruency of the triangles.∠M≈∠Q: Angle M of △LMN is congruent to angle Q of △PQR.∠R≈∠N: Angle R of △PQR is congruent to angle N of △LMN.The statements ∠L≈∠M and NL≈PQ cannot be true based on the given triangle congruencies because ∠L and ∠M are angles within the same triangle (△LMN), and cannot be congruent to each other; and the side NL is not part of triangle △LMN.
