16. An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute. Write an equation to model the situation. Find the altitude of the plane after 5 minutes
Answer:
equation: y=-2,000x+30,000
altitude after five minutes: 20,000
Step-by-step explanation:
y = altitude of the plane
x= slope (the plane descends -2000 feet per min, so the slope is -2000)
the y-intercept is 30,000 as the plane begins at 30000 feet above ground
The hypotenuse of a right triangle is 26 millimeters. One leg of the right triangle is 10 millimeters. What is the length of the other leg? (4 points)
Question 3 options:
1)
18 millimeters
2)
20 millimeters
3)
24 millimeters
4)
28 millimeters
Answer: 24 millimeters
the length of the other leg is x (x > 0)(millimeters)
using Pythagoras theorem with the right triangle, we have:
x² + 10² = 26²
⇔ x² = 26² - 10² = 576
=> x = 24 (mm)
Step-by-step explanation:
Step-by-step explanation:
(26)^2 = (10)^2 + BC^2
676 = 100 + BC^2
576 =BC^2
BC = 24 mm
Find slop for each line
8x-4y=16
Answer:
y=2x-4
Step-by-step explanation:
slope=mx+b
8x-4y=16
-4y=-8x+16
-4y/-4=y
(-8x+16)/-4=2x-4
y=2x-4

You created new playlist, and 100 oi your friends listened to it and shared if they liked the new playlist or nat. Nadhii said the ratio of the number of people who liked the playlist ta the number of people who did nat like the playlist is 75:25. Dylan said that three people who liked the playlist, one person did not. Nadhii and Dylan agree? Prove your answer using the values of the ratios.
Answer:
Yes, Nadhii and Dylan agree
Step-by-step explanation:
You created a new playlist, and 100 of your friends listened to it and shared if they liked the new playlist or not. Nadhii said the ratio of the number of people who liked the playlist to the number of people who did not like the playlist is 75: 25. Dylan said that for every three people who liked the playlist, one person did not.
Do Nadhii and Dylan agree? Prove your answer using the values of the ratios.
Total number of friends who listened = 100
Nadhii said the ratio of the number of people who liked the playlist to the number of people who did not like the playlist is 75: 25.
Nadhii
Number of people who liked the playlist : Number of people who did not like the playlist
= 75 : 25
= 75 / 25
= 3/1
= 3 : 1
Dylan said that three people who liked the playlist, one person did not.
Number of people who liked the playlist : Number of people who did not like the playlist
= 3 : 1
Yes, Nadhii and Dylan agree

A density curve for all the possible temperatures between 0 degrees F and 40 degrees F is a rectangle. What is the height of the rectangle in this density curve?
A. 0.025
B. 0.00025
C. 0.0025
D. 0.25
Answer:
Concept: Higher Level Mathematics
You have a density curve, aka probability You are asked to find the height Hence 0-40F has 40 total integers or values of X(probability) Hence you have a total Area of [tex] \binom{40}{0} [/tex]Integrate f(x) to get 0.025. Hence the answer is A Rate positively and give brainlistPercy has already walked 25 kilometers this week, plus he plans to walk 5 kilometers during
each trip to school. After 12 trips to school, how many kilometers will Percy have walked in
total?
Answer:
85
Step-by-step explanation:
He walked 25 already. So you have x=25. He walks 5 km during each trip. There are 12 trips. 5 times 12 is 60. x=25+60. So, 25 plus 60 is 85.
Help ASAP. Solve both
Step-by-step explanation:
question 15
For y to be parallel to z the sum of given angles must be equal to 180°
3x + 7 + 10x - 22 = 180° add like terms
13x - 15 = 180 add 15 to both sides
13x = 195 divide both sides by 13
x = 15
question 16
If y is parallel to z then the given angles are alternate exterior and has same measurement
11x - 3 = 4x + 39
11x - 4x = 39 + 3
7x = 42 divide both sides by 7
x = 6

Coz they're corresponding angles
double checking
i think a and h but not sure
Answer:
C and G
Step-by-step explanation:
You have two lines intersected by a transversal. The transversal is labeled t. The other two lines are "the two lines".
Corresponding angles must be both on the same side of the transversal and they must be either both above the two lines or both below the two lines.
All 4 pairs of corresponding angles in this figure are listed below:
a, e
c, g
b, f
d, h
The only one of those pairs in the choices is c, g

Answer:
Option A: 6 to 9 , 9/12 is the correct answer.
Step-by-step explanation:
The equivalent ratios simplify to same simple ratio.
In case of this question, we have to check which to the ratios doesn't simplify to 3:4 or 3/4
Option A:
6 to 9 , 9/12
6 to 9 can be written as:
[tex]=\frac{6}{9}\\= \frac{2}{3} \neq \frac{3}{4}[/tex]
9/12 simplifies to 3/4
But as one of the ratio doesn't simplify to 3:4 which means 6 to 9 is not equivalent to 3:4
Hence,
Option A: 6 to 9 , 9/12 is the correct answer.

Answer:
No
Step-by-step explanation:
3x-8+3x+7-(simplified)-> 6x-1, which does not have (x+5) as a factor
Answer:
NoStep-by-step explanation:
Let's assume (x + 5) is the factor of f(x) = x^3 − 4x^2 + 3x + 7
then f(-5) should be equal to zero. Verifying:
f(-5) = (-5)^3 - 4(-5)^2 +3(-5) + 7 =-125 - 100 - 15 + 7 = -233Since -233 ≠ 0, the statement is false, so (x + 5) is not a factor of given polynomial

Answer:
Goran's gas tank is 1/6 full. After he buys 14 gallons of gas, it is 3/4 full. How many gallons can Goran's tank hold?"
Let x = gallons to fill the tank
14
multiply by 12
12*3%2F4x = 12*1%2F6x + 12(14)
3(3x) = 2x + 168
9x - 2x = 168
7x = 168
x = 168/7
x = 24 gallons
:
see if that is true
1%2F6*24 + 14 = 18 gallons which is 18/24 = 3/4 of the tank
