Answer:
a
Step-by-step explanation:
A fighter pilot needs to make an emergency landing. He needs a clear space that is at least 600 m long to land safely. He is flying at an altitude of 300 m. He sees a small empty field. The angles of depression from the jet to the two ends of the field are 30° and 56° [5]
a) How long is the field?
b) Can he land safely?
(a) See the attached sketch. The jet makes a right triangle with the ground with hypotenuse y. Since the angle of depression is 56°, and the plane in which the jet is flying 300 m in the air is parallel with the ground, the angle of elevation in the right triangle is also 56°. Use the definition of sine to solve for y.
sin(56°) = (300 m)/y → y = (300 m)/sin(56°)
The uppermost angle in the blue triangle has measure equal to the difference between the two given angles of depression, 56° - 30° = 26°, and the rightmost angle is also 30° by the same reasoning as before. Then by the law of sines,
x/sin(26°) = y/sin(30°) → x = sin(26°)/sin(30°) y ≈ 317.2627 m
(b) No, the field is not long enough.

Anybody know the answer to this
Ms. Gregg spent $14 buying fruit
• Apples cost $2 per pound
• Bananas cost $1 per pound.
• What are some possible amounts of pounds of apples and
bananas that Ms. Gregg could have bought?
Answer:
Ms. Gregg could buy 4 apples and 6 bananas
Step-by-step explanation:
You can split the money and try to get even on each fruit by, getting 4 apples which would be 8 dollars on 4 apples then the extra money would be left over for the bananas which would be six dollars and since the bananas are only 1 dollar you can buy 6 with the leftover money.

Gail rode her bicycle 325 miles in 5 days.
How many
miles did she ride each day?
Answer:
Our final answer is the average speed is 7 and 2/3 miles per hour
Step-by-step explanation:
We want to find the speed of Maria's bike (miles per hour). Realize that 3/4 of an hour is 45 minutes. So if we take the total miles (5 and 3/4 miles) and divide by 45 mins, we will get the total miles per min.
We can convert 5 and 3/4 miles to a single fraction -----> 5 and 3/4 = 5 +3/4 = 5/1 + 3/4 = 20/4 + 3/4 = 23/4
Now we take 23/4 and divide this number by 45. ( or multiply by 1/45). This answer is 23/180 and THIS NUMBER represents the total amount of MILES PER MIN. BUUUTT we want the total amount of MILES PER HOUR. What do we do?
We take the total miles per minute and multiply this answer (23/180) by 60 minutes [60 mins = 1 hour].
Thus (23/180)*60 = 1380/180 ----------> which is equal to 1260/180 + 120/180 = 7 + 2/3 = 7 and 2/3
Our final answer is the average speed is 7 and 2/3 miles per hour
What are the coordinates of point H?
9514 1404 393
Answer:
(-1 1/2, 3)
Step-by-step explanation:
Coordinates are written as an ordered pair. That means the position of the coordinate value in the pair has significance.
By convention, the first coordinate is the "x" coordinate. It is the number of units the point lies to the right of the x=0 point on the horizontal scale. Here, the point lies between 1 and 2 units left of 0, corresponding to an x-coordinate of -1 1/2. So far, we know the point coordinates are (-1 1/2, <something>).
At this point, you can check to see if this narrows down the answer choices. It does. The only available answer choice with a first coordinate of -1 1/2 is the correct one: (-1 1/2, 3).
__
The second coordinate in the ordered pair is the "y" coordinate. It is the number of units the point lies above the point y=0 on the vertical scale. Here, the point lies 3 units above the point y=0, corresponding to a y-coordinate of 3. Now, we know the coordinates of the point are (x, y) = (-1 1/2, 3).
_____
Additional comment
Ordered pairs of coordinates are not always x- and y- coordinates. Sometimes, they are elevation and azimuth, latitude and longitude, radius and angle. However, for the vast majority of work in Algebra, an ordered pair of coordinates refers to (x, y) coordinates on a Cartesian plane (one with grid lines running horizontally and vertically).

Expand and simplify
(x - 1)(2x + 3)
Answer:
2x^2+x-3
Step-by-step explanation:
Answer:
2x² + x - 3
Step-by-step explanation:
You need to foil the equation.
Foil = (a + b)(c + d) = ac + ad + bc + bd
(x - 1)(2x + 3)
x · 2x = 2x²
x · 3 = 3x
-1 · 2x = -2x
-1 · 3 = -3
Putting them together gets us:
2x² + 3x - 2x - 3
Add like terms to simplify it.
2x² + x - 3

Answer:
How many plates are on the table as it results in only one value with no variability
Step-by-step explanation:
D) How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.
What is Statistic?A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.
Statistics is a method of comprehending data collected about us and the world. For example, if you send a parcel through the mail, it is logged in a massive database.
How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.
A statistical question involves the collection and analysis of numerical data in order to make inferences or draw conclusions about a larger population.
The other questions (A, B and C) all involve the collection and analysis of numerical data and are therefore statistical questions.
Hence, the correct answer would be option (D).

"Frank's favorite drink is coke, but the restaurant only has Pepsi." Simple or Compound sentence?
Answer:
Compound sentence
Step-by-step explanation:
A compound sentence is a group of words that consists of at least two independent clauses. The main difference between simple and compound sentences is that a simple sentence is composed of a single clause whereas a compound sentence is composed of two or more clauses. This means that it's a compound since "Frank's favorite drink is coke" is the first independent clause, and "but the restaurant only has Pepsi", is the second independent clause.

The difference between 32.6 and a number is 10.2. Which equation can be used to solve this problem? 32.6 minus y = 10.2 y minus 36.2 = 10.2 10.2 minus y = 32.6 y + 32.6 = 10.2
Answer:
32.6 - y= 10.2
Step-by-step explanation:
The equation to solve this problem can be written as
32.6 - y= 10.2
Where y is the number that was substracted from 32.6.
If we make y subject of formula we have
y= (32.6-10.2)
y=22.4
Which means the number that was substracted from 32.6 is 22.4 and there difference is 10.2
Answer:
A. 32.6 - y= 10.2

A machine is used to fill bags with a popular brand of trail mix. The machine is calibrated so the distribution of the weights of the bags of trail mix is normal,
with mean 240 grams and standard deviation 3 grams. Of the following, which is the least weight of a bag in the top 5 percent of the distribution?
Answer:
D. 246 grams
Step-by-step explanation:
invnorm(.95, 240, 3) is around 244 and the question is asking for the least weight of a bag in the top 95%, so the smallest number within
a. 234
b. 240
c. 243
d. 246
e. 248
is d.
The distribution of the mix follows inverse normal distribution
The least weight of a bag in the top 5% is 246 grams
The given parameters are:
[tex]\mathbf{\mu = 240}[/tex] ---- population mean
[tex]\mathbf{\sigma = 3}[/tex] ---- population standard deviation
To get the least weight of a bag in the top 5%, we make use of inverse normal distribution.
So, we have:
[tex]\mathbf{Least = invNorm(p,[\mu,\sigma])}[/tex]
Being in the top 5% means that:
p = 1 - 5%
p = 1 - 0.05
p = 0.95
So, we have:
[tex]\mathbf{Least = invNorm(0.95,240,3)}[/tex]
From the inverse normal calculator, we have
[tex]\mathbf{Least = 246}[/tex]
Hence, the least weight is 246 grams

For lines a , c , and d , line c is parallel to line d and m ∠ 1 = 55 ° . Part A: For the given diagram, use the measure of ∠ 1 to find the measure of the remaining seven angles. Part B: In two or more complete sentences, explain the relationship between angle pairs a) ∠ 1 and ∠ 7 and b) ∠ 1 and ∠ 2 . in your explanation, include how you calculated each of the angle measures in the special angle pairs.
Answer:
Part A:
1, 4, 5, and 8 = 55 degrees.
3, 2, 6, and 7 = 125 degrees.
Part B:
I know that angle 1 is 55 degrees so angle 7 would be 125.
I know that angle 1 is 55 and to get angle 2, both angles should add up to 180 so 180 - 55 is 125, that is how I find angle 2 = 125 degrees.
Step-by-step explanation:
This is what I wrote, I hope it helps and tell me if I am wrong but I think it is right.
Have a Meowgical day!
Part A:
The values of the angles are:
∠1 = 55
∠2 = 125
∠3 = 125
∠4 = 55
∠5 = 55
∠6 = 125
∠7 = 125
∠8 = 55
Part B:
∠1 and ∠7 are exterior angles on the same side.
∠1 and ∠2 form a straight angle.
We have,
Part A:
From the figure,
∠1 and ∠5 are corresponding angles.
So,
∠1 = ∠5 = 55
And,
∠1 and ∠8 are alternate exterior angles.
∠1 = ∠8 = 55
And,
∠1 and ∠4 are vertical angles.
∠4 = 55
And,
∠5 and ∠8 are vertical angles.
∠5 = 55
Now,
∠1 and ∠2 form a straight angle.
This means,
∠1 + ∠2 = 180
∠2 = 180 - 55
∠2 = 125
And,
∠5 and ∠6 forms a straight angle.
This means,
∠5 + ∠6 = 180
∠6 = 180 - 55
∠6 = 125
Now,
∠2 and ∠3 are vertical angles.
∠6 and ∠7 are vertical angles.
This means,
∠3 = 125
∠7 = 125
Part B:
∠1 and ∠7 are exterior angles on the same side.
This means,
∠1 + ∠7 = 180
Substituting the values.
55 + 125 = 180
180 = 180
This is true.
And,
∠1 and ∠2 form a straight angle.
This means,
∠1 + ∠2 = 180
55 + 125 = 180
This is true.
Thus,
The values of the angles are:
∠1 = 55
∠2 = 125
∠3 = 125
∠4 = 55
∠5 = 55
∠6 = 125
∠7 = 125
∠8 = 55
And,
∠1 and ∠7 are exterior angles on the same side.
∠1 and ∠2 form a straight angle.
