Answer:
-3Step-by-step explanation:
For two parallel lines. their slope are equal
Find the slope of each of the lines
For line A;
m = 0 -y/0+1
mA = -y/1
For line B;
mB = 9 - 3/8 - 6
mB = 6/2
mB = 3
since their slope are equal hence mA = mB
-y/1 = 3
-y = 3
y = -3
Hence the value of y is -3

The radius of a circle is 13 cm. Find its circumference in terms of pie.
Answer:
26 pi
Step-by-step explanation:
Answer:
531
Step-by-step explanation:
first the formula for finding the circumference of a circle is πr2
where π = 22/7
r = 13x13
hence, circumference = πr2
= 22/7 x 13 x 13
= 22/7 × 169
= 22 x 169/7
= 3718/7
= 531 cm
tour busload of 45 people attended two Florida theme parks on successive days. On Day 1 the entrance fee was $15 per adult, $8 per child, $12 per senior citizen and the total charge was $558. On Day 2 the entrance fee was $20 per adult, $12 per child, $17 per senior citizen and the total charge was $771. How many adults, children, and senior citizens were on this tour bus
Answer: There are 22 adults , 12 children and 11 senior citizens on the tour bus.
Step-by-step explanation:
Let adult = x
children = y
senior citizen = z
Given : Total busload (x+ y + z) = 45
Total charge on day 1 = 558 $ = [tex]15\times x+8\times y+12\times z[/tex]
Total charge on day 2 = 771 $ = [tex]20\times x+12\times y+17\times z[/tex]
Now we have 3 equations : x+ y+z =45
[tex]15\times x+8\times y+12\times z=558[/tex]
[tex]20\times x+12\times y+17\times z=771[/tex]
Solving for them we get: x= 22 , y = 12 and z= 11
Thus there are 22 adults , 12 children and 11 senior citizens.

Answer: 23.94 cm
Step-by-step explanation: I am totally not sure if this is the answer, but think of it this way: Those are 2 semi circles. The formula for the area of a semi circle is A = π * r^2 / 2. For the semi circle with 6 cm, the radius is 3. So we can plug it in the formula. 3.14 * 3^2 / 2, which is 14.13. For the semi circle with 5 cm, the radius is 2.5. Again plug it in and it will be 3.14 * 2.5^2 / 2, which is 9.8125. Then, to get the total area, add the 2 final values together. 9.8125 + 14.13, which is 23.9425. Then it said "round to the nearest hundredth if necessary. We can round to the nearest hundredth, which is 23.94, so that would be the answer. That is just my thought process.
I am not really sure if it's the answer, but take a gander at my thought process and hopefully, you can agree with me.

Answer:
16/33
Step-by-step explanation:
half of 5 is 2.5
half of 11 is 5.5
half of 15 is 7.5
half of 33 is 16.5
so 16/33 is the only fraction less than half of the denominator
hope this helps chu <3
Answer:
16/33
Step-by-step explanation:
because 16 +16 is 32 not 33 and it is a 1 over what it's supposed to be so it's less than 1/2 because 1/2 it technically something divided by 2 because it's half of something.
Determine center point and radius in the equation x^2+y^2-6y+1=0
9514 1404 393
Answer:
center: (0, 3)radius: 2√2Step-by-step explanation:
The equation can be put into standard form by "completing the square" for each variable. The x-term is already a square, so we need do this only for the y-term.
x^2 +(y^2 -6y) = -1
x^2 +(y^2 -6y +9) = -1 +9 . . . . . . add (-6/2)^2 to complete the square
x^2 +(y -3)^2 = 8 . . . . standard form equation
__
Comparing the above equation to the form:
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle centered at (h, k), radius r
we see that (h, k) = (0, 3) and r^2 = 8 ⇒ r = 2√2.
The center point is (0, 3); the radius is 2√2.

Answer:
FL = 54°
Step-by-step explanation:
m<MNF = ½(ML + LF) (inscribed angle theorem)
7 + 8x = ½(72 + 7x + 5)
Solve for x
2(7 + 8x) = 72 + 7x + 5
14 + 16x = 72 + 7x + 5
Add like terms
14 + 16x = 77 + 7x
16x - 7x = 77 - 14
9x = 63
x = 63/9
x = 7
✅FL = 7x + 5
Plug in the value of x
FL = 7(7) + 5 = 49 + 5
FL = 54°

A bank took a random sample on processing time in days for loan approvals: 73, 19, 16, 64, 28, 31,90, 60, 56 and 28 What is the standard deviation of this sample?
Answer:
The standard deviation of this sample is 25.35
Step-by-step explanation:
Standard deviation for a sample:
Square root of the sum of the squared differences between each value and the mean, and divided by one less than sample size.
Finding the mean:
The mean is the sum of all values divided by the number of values.
In this question, there are 10 values. So
[tex]M = \frac{73+19+16+64+28+31+90+60+56+28}{10} = 46.5[/tex]
Standard deviation:
[tex]s = \sqrt{\frac{(73-46.5)^2+(19-46.5)^2+(16-46.5)^2+(64-46.5)^2+(28-46.5)^2+(31-46.5)^2+(90-46.5)^2+(60-46.5)^2+(56-46.5)^2+(28-46.5)^2}{9}} = 25.35[/tex]
The standard deviation of this sample is 25.35

Quadrilateral ABCD is inscribed in circle O as shown below.
Which of the following would be used to find the m∠3?
A. 90°+m∠4
B. 180°−m∠1
C. 270°+m∠2
D. 360°−(m∠1+m∠2)
Answer:
A. 90°+m∠4
Step-by-step explanation:
Also
∠ A + ∠ C = 180 o = ∠ B + ∠ D
⇒ 2 x+ ( 3 x − 5 ) = 180 0 = ( x + 5 ) + ∠ C
5 x − 5 = 180
Add 5 to both sides
5 x = 185
Divide both sides by 5
x = 185 5 = 37
But it was A. 90°+m∠4
The equation to use to find angle m∠3 is 180 - m∠1.
Option B is the correct answer.
We have,
In a quadrilateral the opposite angle is supplementary.
This means,
The sum of the opposite angles is 180.
Now,
m∠1 + m∠3 = 180
Solving for m∠3.
m∠3 = 180 - m∠1
Thus,
The equation to use to find angle m∠3 is 180 - m∠1.

You recently sent out a survey to determine if the percentage of adults who use social media has changed from 66%, which was the percentage of adults who used social media five years ago. Of the 2809 people who responded to survey, 1634 stated that they currently use social media. Use the data from this survey to construct a 98% confidence interval estimate of the proportion of adults who use social media.
Answer:
The 98% confidence interval estimate of the proportion of adults who use social media is (0.56, 0.6034).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Of the 2809 people who responded to survey, 1634 stated that they currently use social media.
This means that [tex]n = 2809, \pi = \frac{1634}{2809} = 0.5817[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5817 - 2.327\sqrt{\frac{0.5817*4183}{2809}} = 0.56[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5817 + 2.327\sqrt{\frac{0.5817*4183}{2809}} = 0.6034[/tex]
The 98% confidence interval estimate of the proportion of adults who use social media is (0.56, 0.6034).

Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the Gazebo blend with the Mexican Shade Grown blend, but always in the same proportion. Yesterday, you mixed 90 pounds of the Gazebo blend with 27 pounds of the Mexican Shade Grown blend. Today, there is 60 pounds of the Gazebo coffee left in stock. How many pounds of the Mexican Shade Grown coffee should you mix with it to get your secret blend?
Answer:
18lbs of Mexican Shade Grown coffee
Step-by-step explanation:
Since this is a ratio problem and we are given three values and one variable x (pounds of Mexican Shade Grown coffee needed) we can use the Rule of Three to solve this problem. In this rule we simply multiply the diagonal available values and divide by the third value to get the value of the variable, like so...
90lbs Gazebo <=====> 27lbs Mexican Blend
60lbs Gazebo <=====> x lbs Mexican Blend
(60 * 27) / 90 = x
1620 / 90 = x
18 lbs = x
We need 18lbs of Mexican Shade Grown coffee blend to mix with the 60lbs of Gazebo blend

3 in.
5 in.
228 square inches
4 in. 4 in.
234 square inches
24 in.
8 in.
Answer:
234 square inches
Step-by-step explanation:
Ok take this shape step by step. First solve the rectangle.
The area of the rectangle would be: 24 * 8 = 192
Rectangle Area: 192
Then, solve the area for the triangle in the middle.
The area of that triangle would be: 8 * 3 divided by 2. You get 8 by the base of the triangle, 4 + 4. 3 is of course, the height. Lastly, you divide this by 2 because that is the formula for the area of a triangle. When you solve, you get 12.
Middle Triangle Area: 12
Then solve for the last triangle.
Doing the same thing, the area for that triangle is 12 * 5 divided by 2. So solve, 12*5 = 60, 60/2 = 30
Last Triangle area: 30
Finnally, add all the areas up,
192 + 12 + 30 = 234
