Answers
Answer:
Shown in the picture
Step-by-step explanation:
A:
Set the value of x to "5" and "30" to find the corresponding values of y (i.e. the altitudes of the plane at 5 or 30 minutes after beginning descent).
B:
Use the the same method to determine the set of coordinates (/ordered pairs) at each of the values for x given in part B of the question.
C:
The initial value is simply the starting value of y, or in other words, the altitude at which the plane begins to descend in this context;
So it will be 0 mins after the beginning of descent of the plane, i.e. when x = 0, therefore the answer is (0, 28000) as an ordered pair or simply 28000 ft.
D:
Rate of change is a fancy or more technical way of referring to the gradient of a function;
In this case of the context of a plane descending, it refers to the change in altitude over time;
This can be calculated using any two ordered pairs (or coordinates as I call them) using the formula of the difference in the y values divided by the difference in the x values.

Using elimination
Answers
Answer:
look at the picture shown
Answer:
x = 9 ; y = -1
Step-by-step explanation:
because one equation is 3y and the second is -3y they will cancel out (eliminate) so the term y will be gone and you combine (add) the rest of the terms and end up with
[tex]2x=18[/tex]
then divide both sides by 2 to get: x = 9
plug in the value of x into one of the original problems
[tex]9+3y=6[/tex]
and solve for y
[tex]3y=-3\\y=-1[/tex]
if you plug in the values of x and y into the equations it should be true
Jarret walks his puppy outside every day for 30 minutes. Angela walked her puppy every day for 90 minutes. Find the number of minutes that each puppy was walked for 1, 2, 3, and 4 days. Then graph the results as ordered pairs. How many more minutes does Angela spend walking her puppy over 2 days compared to Jarret walking his puppy over 2 days?
Answers
Answer:
Read the answers below, including the graph.
Step-by-step explanation:
1. Let's find the number of minutes that each puppy was walked for 1, 2, 3, and 4 days.
Day 1 Day 2 Day 3 Day 4
Angela 90 180 270 360
Jarret 30 60 90 120
Ordered pairs for Angela's puppy: (1,90); (2,180); (3,270); (4,360)
Ordered pairs for Jarret's puppy: (1,30); (2,60); (3,90); (4,120)
2. How many more minutes does Angela spend walking her puppy over 2 days compared to Jarret walking his puppy over 2 days?
180 - 60 = 120
Angela spend walking her puppy 120 more minutes over 2 days compared to Jarret
Express the following in scientific notation 77.31 × 10^4
Answers
The number 77.31 x 10^4 in scientific notation is 7.731 x 10 ^ 5. To achieve this, the decimal place was moved to the left and the power of 10 increased accordingly.
Explanation:To express the number 77.31 x 10^4 in scientific notation, we need to adjust it to fit the format 'a x 10^n', where 1 ≤ |a| < 10 and n is an integer. So, the main step is to transfer the decimal place in '77.31' to after the first digit, followed by multiplying by an appropriate power of 10.
Firstly, rewrite 77.31 as 7.731 by moving the decimal place one place to the left. Now, since our original number was multiplied by 10^4, this needs to be amended by 1 place for the movement of the decimal point. This results in 10^5, since you are now multiplying by 10 one more time than before.
Combining these, the given number is represented in scientific notation as 7.731 x 10 ^ 5.

Step-by-step explanation:
Chords NP and MQ intersect at point S in circle R.
If MS = 3, NS = 2, and SQ = 8, what is the length of SP?
Answers
Option C:
The length of SP is 12.
Solution:
In the given circle, NP and MQ are chords of the circle.
MS = 3, NS = 2, SQ = 8
To find the length of SP:
Segments of chords theorem:
If two chords intersects in the interior of a circle, then the product of the lengths of the segment of one chord is equal to the product of lengths of the segments of the other chord.
By this theorem,
NS × SP = MS × SQ
⇒ 2 × SP = 3 × 8
⇒ 2 SP = 24
Divide by 2 on both sides of the equation, we get
⇒ SP = 12
Option C is the correct answer.
The length of SP is 12.
Final answer:
Using the Intersecting Chord Theorem, we find that the length of SP is 3/4 by setting up the equation 3 * 2 = SP * 8 and solving for SP.
Explanation:
The student is asking about finding the length of a chord segment in a circle where two chords intersect. Since chords NP and MQ intersect at point S inside circle R, we can apply the Intersecting Chord Theorem.
This theorem states that the product of the lengths of the segments of one chord is equal to the product of the lengths of the segments of the other chord. In formula terms, MS × NS = PS × SQ.
We are given MS = 3, NS = 2, and SQ = 8. To find the length of SP, we just substitute into the theorem's formula: (3) × (2) = SP × (8). From this, we calculate that SP = 3/4, which is the length of the segment SP.

Answer:
I have bought 4 shirts and 6 pants.
Step-by-step explanation:
Let I have bought x number of shirts and y number of pants.
So, the two equation that we can write from the given conditions are
x + y = 10 ............. (1) and
24x + 32y = 288 ...... (2)
Now, solving equations (1) and (2) we get
24x + 32(10 - x) = 288
⇒ 8x = 320 - 288 = 32
⇒ x = 4
And y = (10 - 4) = 6

Answer:
The height of the cone is [tex]9 \ cm[/tex]
Explanation:
It is given that the radius of the cone is [tex]3 \ cm[/tex]
The volume of the cone is [tex]27\pi[/tex]
The height of the cone can be determine using the formula,
[tex]$V=\frac{1}{3} \pi r^{2} h$[/tex]
Substituting the values [tex]V=27 \pi[/tex] and [tex]r=3[/tex], we get,
[tex]$27 \pi=\frac{1}{3} \pi(3)^{2} h$[/tex]
Multiplying both sides by 3, we have,
[tex]$81 \pi= 9\pi h$[/tex]
Dividing both sides by [tex]$9 \pi$[/tex], we have,
[tex]9=h[/tex]
Thus, the height of the cone is [tex]9 \ cm[/tex]

There are 142 laptops and desktop computers in a lab. There are 6 more laptops than desktops. What is the total number of laptops in the lab

Step-by-step explanation:
142/2=71
71+6=77
71-6+65
Answer:
74 Labtops
Step-by-step explanation:
you first have to subtract 6 from 142
142-6= 136
divide 136 by two.... for the labtops and the computers.
136 ÷ 2 = 68
68 is the number of desktops...to find the number of labtops you just need to add 6 again.
68 + 6 = 74 Labtops
To check your answer you can just add
74+68 and if it equals to what you started with then that's your answer
74 + 68 = 142
Hugo and Koby are measuring the heights of plants in biology class.
Use the drop-down menus to complete the statements about the measured heights and the actual heights of the plants.
Answers
The answers are shorter, higher, 2cm, 15cm, 20% and 15%.
Step-by-step explanation:
Step 1; From the given data Hugo measured his plant higher than its original height. Hugo measured his plant as 12 cm while it was actually 10 cm. So Hugo's measurement was off by 2cm. Hugo's percent error is given by dividing the difference in values by the actual value.= multiplied by 100.
% error = (difference in values / actual value) × 100
Hugo's % error = (12 - 10)/ 10 × 100 = 2/10 × 100 = 20%.
Step 2; Koby measured his plant lower than his plant's original height. He measured it to be 85 cm while it was 100 cm tall. So Koby's measurement was off by 15cm. The percent error is calculated in the same way.
% error = (difference in values / actual value) × 100
Koby's % error = (100 - 85)/ 100 × 100 = 15/100 × 100 = 15%.
Step 3; Hugo had a percent error of 20% while Koby has a percent error of 15%. So Hugo had a higher percent error of the two.

Answer:

Step-by-step explanation:
In isosceles triangle KNM, NL is a perpendicular bisector of angle KNM.
This means

Since
[tex]m\angle KNL=(5x+10)^{\circ}\\ \\m\angle LNM=(6x-1)^{\circ},[/tex]
you have
[tex]5x+10=6x-1\\ \\5x-6x=-1-10\\ \\-x=-11\\ \\x=11[/tex]
No, find the measure of angles KNL and LNM:
[tex]m\angle KNL=(5\cdot 11+10)^{\circ}=65^{\circ}\\ \\m\angle LNM=(6\cdot 11-1)^{\circ}=65^{\circ}[/tex]
and the measure of angle KNM is
[tex]m\angle KNM=m\angle KNL+m\angle LNM=65^{\circ}+65^{\circ}=130^{\circ}[/tex]
Angles adjacent to the base of isosceles triangle are congruent. The sum of the measures of all interior angles is 180°, then

The ratio of orange fish to black fish is 5 : 8Nanci has a total of 20 orange fishWe need to find how many black fish in the tank
∵ The ratio between the orange fish to the black fish is 5 : 8
∵ She has 20 orange fish
By using the ratio method
→ orange : black
→ 5 : 8
→ 20 : x
By using cross multiplication
∵ 5 × x = 20 × 8
∴ 5 x = 160
- Divide both sides by 5
∴ x = 32
∵ x represents the number of the black fish
∴ The number of the black fish is 32
