A plane flies 1.6 hours at 150 mph on a bearing of 10°. It then turns and flies 9.1 hours at the same speed on a
bearing of 100°. How far is the plane from its starting point?
9514 1404 393
Answer:
1386 miles
Step-by-step explanation:
The plane flies ...
(150 mi/h)(1.6 h) = 240 mi
on its first leg. Then it flies ...
(150 mi/h)(9.1 h) = 1365 mi
on the second leg. The flight directions differ by 90°, so the distance from the starting point can be found using the Pythagorean theorem.
c² = 240² +1395² = 1920825
c = √1920825 ≈ 1385.94
The plane is about 1386 miles from its starting point.

One of my homework problems say: Solve the proportion. X/4=2/5. I am stuck on this one. It will be appreciated if you explain the steps to complete this problem. Thanks for your help!
Answer:
1.6
Step-by-step explanation:
Given :
X/4 = 2/5
To solve for X ;
We can use cross multiplication ; multiply opposite values :
X * 5 = 2 * 4
5X = 8
To isolate X ;
Divide both sides by 5
5X/5 = 8/5
X = 8/5
X = 1.6

If 16 blue cones are there, and the blue cones are 50 % of all cones, tat means that half or 50% of all cones are blue.
50% +50% = 100%
And hence,
16 + 16 = 32 blue cones

Find the value of each variable in the parallelogram
Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10
___________________________________________
Hope that helped. Good luck.
Answer:
7.) y=8, x=7
8.) y=3, x=11
9.) h=65, k=10
Step-by-step explanation:
First, let's start with #7. By definition of a parallelogram, we can say that opposite sides are congruent, meaning 2y-7=9 and 3x+2=23.
So, solving these problems-
2y-7=9
2y=16
y=8
3x+2=23
3x=21
x=7
Now, let's move on to #8. For this, a defining property of a parallelogram is that the diagonals bisect each other. So, 3y+5=14 and 2x-5=17.
Let's solve these equations-
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
Now, finally #9. Another defining property of a parallelogram is that opposite angles are congruent. So, 2h=130 and 5k=50.
So, h= 65 and k= 10.
State the null and alternative hypothesis: The average score of 40 high school basketball games is less than 26
Answer:
[tex]H_o:\mu = 26[/tex]
[tex]H_a:\mu < 26[/tex]
Step-by-step explanation:
Given
Average score is less than 26
Required
Determine the null and alternate hypothesis
Since the average is said to be less than 26; that represents the alternate hypothesis.
The null hypothesis will be:
[tex]Average = 26[/tex]
So, we have:
[tex]H_o:\mu = 26[/tex]
And the alternate hypothesis
[tex]H_a:\mu < 26[/tex]

The state fair is a popular field trip destination. This year the senior class at High School A and he senior class at High School B both planned trips there. The senior class at High School A rented and filled 2 vans and 5 buses with 307 students. High School B rented and filled 6 vans and 10 buses with 626 students. Each van and each bus carried the same number of students.Find the number of students in each van and in each bus.
Let x = number of students in each van
y = number of tudents in each bus
Equation 1: 2x+5y=307
Equation 2: 6x+10y=626
Part A: Which method will you use to solve this problem? (Graphing (Rewrite equations in slope intercept form first), Substitution, or elimination) ATTACH YOUR WORK
Part B: How many students can a van carry?
How many students can a bus carry?
Answer:
Use elimination, x = 6, y = 59
Step-by-step explanation:
1) Multiply Equation 1 by 2
E1: 4x +10y = 614
E2: 6x+10y = 626
2) Subtract E2 from E1
-2x = -12
x = 6
3) Substitute x = 6 into one of the equations (I used the original Equation 1)
2(6) +5y = 307
12+ 5y = 307
5y = 295
y = 59
A van can carry 6 students, and a bus can carry 59 students.

For the diagram shown, which angles are alternate interior angles?
Answer:
∠3 and ∠5
Step-by-step explanation:
Find the missing angle.
(137°
102°
?
Answer:
66°
I hope it helps.........
The missing angle ∠ABC is 35°.
Let the missing angle be x and y To find the missing angle y, we need to solve the equation 102° + x + y = 180, where x and y are angles.
Given that x + 137 = 180, we can substitute the value of x in terms of 180 - 137:
x = 180 - 137
x = 43°
Now, we can substitute the value of x into the equation y =∠ABC
102° + x + y = 180
102° + 43° + y = 180
Combining like terms:
145° + y = 180
To find y, we subtract 145° from both sides:
y = 180 - 145
y = 35°
Therefore, the missing angle ∠ABC is 35°.

Which equation is graphed along with the parent function?
g(x) = RootIndex 3 StartRoot x + 3 EndRoot + 4
g(x) = RootIndex 3 StartRoot x minus 3 EndRoot + 4
g(x) = RootIndex 3 StartRoot x minus 4 EndRoot + 3
g(x) = RootIndex 3 StartRoot x + 4 EndRoot + 3
Answer:
B. g(x) = RootIndex 3 StartRoot x minus 3 EndRoot + 4
Step-by-step explanation:
edg 2021 .. its correct
The equation that is graphed along with the parent function is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]
The parent function is a cube root function, represented as:
[tex]f(x) = \sqrt[3]{x}[/tex]
First, the parent function is horizontally shifted right by 3 units
The rule of this transformation is:
[tex](x,y) \to (x - 3,y)[/tex]
So, we have:
[tex]f'(x) = \sqrt[3]{x - 3}[/tex]
Next, the transformed function is vertically shifted up by 4 units
The rule of this transformation is:
[tex](x,y) \to (x,y+4)[/tex]
So, we have:
[tex]g(x)=\sqrt[3]{x-3} +4[/tex]
Hence, the equation is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]
