Answer:
Private Jet = 181 mph Commercial Jet = 362 mph
Step-by-step explanation:
private jet travels distance D in 14 hours
commercial jet travels distance D in 7 hours
so commercial jet speed is twice the private jet
y = 2x
commercial jet speed = 3 · (private jet speed) - 181 mph
y = 3x - 181
2x = 3x - 181
2x - 3x = -181
-x = -181
x = 181
y = 2x
y = 362
362 = 3(181) - 181
A dodecahedral die (one with 12 sides numbered from 1 to 12) is tossed once. Find the following probability. (Enter your probability as a fraction.)
The number on the upward face is not 4.
Answer:
11/12
Step-by-step explanation:
::::::::::::::::
The probability of the number on the upward face is not 4 would be 11/12 or 0.92 by calculating as follows:
Solution:
The possible outcomes for rolling a dodecahedral die, numbered from 1 to 12, once is given below in the term of sample space S:
S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
Therefore,
n(S) = 12
Event A: Sample space in the case of not having number 4 on the upward face:
A = {1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12}
therefore,
n(A) = 11
the probability of an event can be calculated by:the required probability = [tex]\dfrac{\text{Number of times event A, occurred}}{\text{Number of times this experiment performed}}[/tex]
then putting the space values here;
= [tex]\frac{n(A)}{n(S)}=\frac{11}{12}=0.92[/tex]
Thus, the required probability is 0.92

Answer:
A. y = 4.5x
Step-by-step explanation:
y is the length of the fish and x is the time, by checking each equation with values in the table you can see that this is the one that represents the relationship.
Example using (4 yrs, 18 cm):
A: 18 = 4.5(4) ✅
B: 4 = 4.5(18) ❌
C: 4 = 9(18) ❌
D: 18 = 9(4) ❌
An isosceles triangle has an angle that measures 116°. Which other angles could be in that isosceles triangle? Choose all that apply.
Answer:
Step-by-step explanation:
since we know that triangles have 180° we know that 116° is two much if it's doubled 2*116 = 232° so that angle has to be the single angle and the left over of 180 - 116 is the left over amount that is even divided into the last two angles so 180 - 116 = 64 / 2 = 32° so the triangle is made up of 116 + 32 + 32 degree angles

Someone helppp pls :(((((
Answer:
y = ½x + 8
Step-by-step explanation:
✔️First, find the slope (m) using any two given pairs of values, say (0, 8) and (2, 9):
Slope (m) = change in y/change in x
Slope (m) = (9 - 8)/(2 - 0)
Slope (m) = 1/2
m = ½
✔️Find the y-intercept (b):
The y-inteeceot of the function would be the value of y when x = 0.
Form the table, when x = 0, y = 8. Therefore:
y-intercept (b) = 8
✔️To write the equation of the function, substitute m = ½ and b = 8 into y = mx + b.
Thus:
y = ½x + 8
Please help me. Thank you very much. （╹◡╹）
Answer and Step-by-step explanation:
First, you find the x-value of f(x) on the graph, and find the corresponding y-value.
On the graph, we see that when we go to the x-value of -7, we are at a y-value of 0. Now, we plug this in to the g(x) function and look for the y-value on the g(x) graph.
When 0 is plugged in for x in g(x), we get the y-value to be 5.
This means that the value of g(f(-7)) is 5.

the sum of 2 numbers is 56.twice the smaller number exceeds one-half the larger number by 22.find the numbers
9514 1404 393Answer:
20, 36
Step-by-step explanation:
Let x and y represent the smaller and larger numbers, respectively. The given relations let us write two equations:
x + y = 56 . . . . . . the sum of the two numbers is 56
2x -y/2 = 22 . . . . twice the smaller exceeds half the larger by 22
We can solve this by multiplying the second equation by 2 and adding the first.
2(2x -y/2) +(x +y) = 2(22) +56
5x = 100 . . . . . . simplify
x = 20
y = 56 -20 = 36
The two numbers are 20 and 36.
