Answer:
2.44ftStep-by-step explanation:
In this problem, we are going to use Pythagoras theorem to solve for the height
given
x= 4.6 ft
hypothenus=15.2
y=?
we know that
hyp^2=x^2+y^2
15.2=4.6^2+y^2
15.2-4.6^2=y^2
15.2-21.16=y^2
5.96=y^2
√5.96=y
y=2.44ft
the height of the ladder is 2.44ft

Kevin wrote a total of 12 pages over 3 hours. How many hours will Kevin have to spend writing this week in order to have written a total of 20 pages? Assume the relationship is directly proportional.
Answer:
It will take him 5 hrs to write a 20-page essay because he can write 4 pages in 1 hour.
Hope this helps!
Answer:
5 hours
Step-by-step explanation:
For 12 pages, he spent 3 hours. So it takes him 1 hour to write 4 pages. (12 ÷ 3 = 4) If for each 4 pages 1 hour is spent respectively, then for 20 pages: 20 ÷ 4 = 5 hours will be spent.

The Nike factory has just finished up a new order of Air Jordan XIII sneakers to be released soon. They just produced 5,814 new pairs of the sneakers. If the company wants to evenly distribute the sneakers evenly among their 17 warehouses, how many pairs of the Air Jordan sneakers will each warehouse receive?
Answer:
342 pairs
Step-by-step explanation:
Given that,
New pair of sneakers produced by the Nike factory = 5,814
The company wants to distribute the sneakers evenly among their 17 warehouses.
We need to find the no of pairs of the Air Jordan sneakers will each warehouse receives. It can be calculated as follows :
[tex]n=\dfrac{\text{total pair of sneakers}}{\text{no of warehouses}}\\\\n=\dfrac{5814}{17}\\\\n=342[/tex]
It would mean that each warehouse will receive 342 pair of sneakers.
A new hospital tracked the number of births during its first 6 months of operation, as shown in the table. A 2-column table with 6 rows. The first column is labeled month with entries 1, 2, 3, 4, 5, 6. The second column is labeled number of births with entries 137, 110, 93, 70, 65, 77. Find a quadratic function that models the data. Round numerical values to the nearest whole number. F(x) = x2 x Use the function to predict the number of births for month 8. There will be about births.
The hospital uses the quadratic model to predict the number of births
The equation of the quadratic model is f(x) = 4 x^2 -43 x +178, and the number of births for month 8 is 90
How to determine the quadratic modelTo determine the quadratic model, the make use of a graphing calculator, that has the following calculation summary
a = 4.339 b = -43.461 c = 178.3A quadratic model is represented as:
[tex]y= ax^2 + bx + c[/tex]
So, we have:
[tex]y = 4.339 x^2 -43.461 x +178.3[/tex]
Approximate
[tex]y = 4 x^2 -43 x +178[/tex]
Rewrite as:
[tex]f(x) = 4 x^2 -43 x +178[/tex]
At the 8th month, we have x = 8.
So, the function becomes
[tex]f(8) = 4 * 8^2 -43 *8 +178[/tex]
[tex]f(8) = 90[/tex]
Hence, the number of births for month 8 is 90

A teacher has a large container of blue, red, and green beads. She reports to the students that the proportion of blue beads in the container is 0. 30. The students feel the proportion of blue beads is lower than 0. 30. A student randomly selects 60 beads and finds that 12 of the beads are blue. The P-value for the test of the hypotheses, H0:p=0. 30 and Ha:p<0. 30, is 0. 45. What is the correct interpretation of this value?
There is a 4. 5% chance the proportion of blue beads in the container is 0. 3.
Assuming the true proportion of blue beads in the container is 0. 30, there is a 4. 5% probability that the null hypothesis is true.
Assuming the true proportion of blue beads in the container is 0. 30, there is a 4. 5% probability that the sample proportion would be 0. 20 or less by chance alone.
Assuming the true proportion of blue beads in the container is less than 0. 30, there is a 4. 5% probability that the sample proportion would be 0. 20 or less by chance alone
Answer: C
Step-by-step explanation:
P - Value
Is the evidence against the null hypothesis.
The lower the p-value, the greater the chance of rejection of the null hypothesis.
The greater the p-value, the greater the chance to accept the null hypothesis.
So, in other words, the question asks the probability of having accepted a null hypothesis.
So using the above statement we can say that statement C is true.

Answer:
x = 15
Step-by-step explanation:
The given angles are same- side interior angles and are supplementary, thus
6x + 7 + 3x + 38 = 180, that is
9x + 45 = 180 ( subtract 45 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
Answer:
x = 15
Step-by-step explanation:
these two angles are actually supplementary, which means they add up to 180.
using this, you can make this equation:
3x + 38 + 6x + 7 = 180
combine like terms.
3x + 6x + 38 + 7 = 180
9x + 45 = 180
subtract 45 from both sides.
9x = 135
divide both sides by 9
x = 15

Step-by-step explanation:
Adam must fly home to city A from a business meeting in city B. One flight option flies directly to city A from B, a distance of about 467.3 miles. A second flight option flies first to city C and then connects to A. The bearing from B to C is N28.7E, and the bearing from B to A is N60.7E. The bearing from A to B is S60.7W, and the bearing from A to C is N79.1W. How many more frequent flyer miles will Adam receive if he takes the connecting flight rather than the direct flight?
Answer:
The value is [tex] k =109.6 \ miles [/tex]
Step-by-step explanation:
The diagram illustrating the question is shown on the first uploaded image
From the question we are told that
The distance from city A to B is AB = 467.3 miles
The bearing from B to C is [tex]\theta_{BC} = N 28.7E[/tex]
The bearing from B to A is [tex]\theta_{BA} = N 60.7E[/tex]
The bearing from A to B is [tex]\theta_{AB} = S60.7W[/tex]
The bearing from A to C is [tex]\theta_{AC} = S79.1W[/tex]
Generally from the diagram
[tex]\theta_A = 180 - 60.7 -79.1[/tex]
=> [tex]\theta_A = 40.2 ^o[/tex]
Also
[tex]\theta_B = 32^o [/tex]
and
[tex]\theta_C = 180 - (\theta_A +\theta_B )[/tex]
=> [tex]\theta_C = 180 - (40.2 + 32 )[/tex]
=> [tex]\theta_C = 107.8 ^o[/tex]
Generally according to Sine Rule
[tex]\frac{BC}{sin (\theta_A)} = \frac{CA}{sin (\theta_B)} =\frac{AB}{sin (\theta_C)}[/tex]
=> [tex]\frac{BC}{sin (40.2)} = \frac{CA}{sin (32)} =\frac{467.3 }{sin (107.8)}[/tex]
So
[tex]\frac{BC}{sin (40.2)} = \frac{467.3 }{sin (107.8)}[/tex]
=> [tex]BC = 316.8 \ miles[/tex]
Also
[tex]\frac{CA}{sin (32)} = \frac{467.3 }{sin (107.8)}[/tex]
[tex]CA = 260 .1 \ miles [/tex]
Generally the additional flyer miles that Adam will receive if he takes the connecting flight rather than the direct flight is mathematically represented as
[tex]k = [CA +BC] - AB [/tex]
=> [tex] k = [260 .1 +316.8]- 467.3 [/tex]
=> [tex] k =109.6 \ miles [/tex]

The midpoint of AB is M(4,4). If the coordinates of A are (2, 1), what are the
coordinates of B?
Answer:
(6, 7)
Step-by-step explanation:
Hope this helps.
The midpoint of the line segment AB is M. Then the coordinate of the point B will be (6, 7).
What is the mid-point of the line segment?Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).
Then the coordinate of the mid-point of the line segment is given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
The midpoint of AB is M(4,4). If the coordinates of A are (2, 1). Then the coordinate of the point B will be given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
(4, 4) = [(2 + x₂) / 2, (1 + y₂) / 2]
Compare the abscissa, then we have
(2 + x₂) / 2 = 4
(2 + x₂) = 8
x₂ = 8 - 2
x₂ = 6
Compare the ordinate, then we have
(1 + y₂) / 2 = 4
1 + y₂ = 8
y₂ = 8 - 1
y₂ = 7
The midpoint of the line segment AB is M. Then the coordinate of the point B will be (6, 7).
