Answer:
1150 km/hr
Step-by-step explanation:
Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours
In the question we are given the following parameters.
The length of a planet's orbit around a star = Distance = 17,650,000 km.
Time taken to complete a full orbit = 640 Earth days
Step 1
We need to convert the time in days to hours
1 Earth day = 24 hours
640 Earth days =
We cross multiply
640 Earth days × 24 hours
= 15360 hours.
Step 2
Average Speed = Distance in Kilometers/ Time in Hours
Average Speed = 17,650,000 km. /15360 hours
Average Speed = 1149.0885417 km/hr
Approximately to 3 significant figures=
1150 km/hr
Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr

Rate of change =
Answer: -3/-1 or 3/1 is the rate of change
Step-by-step explanation:
(0,2)
(3,3) 0-3==-3
2-3= -1
-3/-1
Answer:
The rate of change ( or slope) is 3.
Step-by-step explanation:
The formula for slope is y2-x2 over y1-x1. Easier terms: subtract two points from eachother, y being the numerator and x being denominator. Two points on this graph are (2,0) and (3,3). When you put y on top, you get 0/2-3/3. The answer is -3/-1, which is equal to 3
A much easier way when you're graph looks like this, is to count the units up/down and right/left, putting the up/down number on top. Since it goes 3 up and 1 right, you get 3/1, or 3.

elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51
Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
Answer:
Other answer is incorrect. Elijah's new balance would be $322.59

Jaira is having pizza for her birthday party. She can make two small pizzas, each with a radius of 6 inches, or one large pizza with a radius of 12 inches. Which option will give her more square inches of pizza?
Answer: One large pizza with a radius of 12 inches
Step-by-step explanation:
Hi, to answer this question we have to calculate the area of each option.
Area of a circle: π r^2
Option 1: two small pizzas, each with a radius of 6 inches.A = π r^2 = π 6^2 = 113.1 in2
Since there are 2 small pizzas we have to multiply the area by 2:
113.2 x 2 = 226.2 in2
Option2 = one large pizza with a radius of 12 inchesA = π r^2 = π 12^2 = 452.38 in2
Since 452.38 in2 > 113.1 in2
Option 2 (one large pizza) will give her more square inches of pizza
Feel free to ask for more if needed or if you did not understand something.

A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected at a time, and once a marble is selected, it is replaced. Find each probability. P(red and yellow)
Answer:
red = 3/13
yellow = 6/13
blue= 4/13
Step-by-step explanation:
breainliest really needed!!
The probability of selecting the red marble and yellow marble is 18/169.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, a bag contains 3 red, 4 blue, and 6 yellow marbles.
Total number of outcomes = 3+4+6=13
Probability of selecting red marble = 3/13
Probability of selecting yellow marble = 6/13
So, P(red and yellow) = 3/13 × 6/13
= 18/169
Therefore, the probability of selecting the red marble and yellow marble is 18/169.

The loudness, L. measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
L - 10log , where lo - 10- and is the least intense sound a human ear can hear. Jessica is listening to soft music at a
sound intensity level of 109 on her computer while she does her homework. Braylee is completing her homework while
listening to very loud music at a sound intensity level of 10 on her headphones. How many times louder is Braylee's music
than Jessica's?
Answer:
Option A is correct.
Braylee's music is 3 times louder than Jessica's.
Step-by-step explanation:
Full Complete Questions
The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
L = 10log (I/I₀), where lo = 10⁻¹² W/m²
and is the least intense sound a human ear can hear.
Jessica is listening to soft music at a sound intensity level of 10⁻⁹ W/m² on her computer while she does her homework.
Braylee is completing her homework while listening to very loud music at a sound intensity level of 10⁻³ W/m² on her headphones. How many times louder is Braylee’s music than Jessica’s?
times louder
3 times louder
30 times louder
90 times louder
Solution
The loudness of a sound intensity is given as
L = 10 log (I/I₀)
For Jessica
I = 10⁻⁹ W/m²
I₀ = 10⁻¹² W/m²
L = 10 log (10⁻⁹/10⁻¹²)
L = 10 log (10³)
L = 10 × 3 = 30 dB
For Braylee
I = 10⁻³ W/m²
I₀ = 10⁻¹² W/m²
L = 10 log (10⁻³/10⁻¹²)
L = 10 log (10⁹)
L = 10 × 9 = 90 dB
How many times louder is Braylee's music than Jessica's?
The factor by which Braylee's music is louder than Jessica's = (90/30) = 3
Braylee's music is 3 times louder than Jessica's.

Find the next two terms of the sequence:
2050, 1990, 1930, 1870, 1810, 1750
The next two terms of the sequence are
Answer:
The answer is 1690, and then 1630
Step-by-step explanation:
2050, 1990, 1930, 1870, 1810, 1750, 1690, 1630
Each number is going down by 60
===============================================================
Explanation:
This is an arithmetic sequence. We are adding -60 to each term to get the next term. Put another way, we are subtracting 60 from each term to get the next.
term 1 = 2050
term 2 = (term1) + (-60) = (term1) - 60 = 2050 - 60 = 1990
term 3 = (term2) + (-60) = (term2) - 60 = 1990 - 60 = 1930
term 4 = (term3) + (-60) = (term3) - 60 = 1930 - 60 = 1870
and so on
Keeping this pattern up, we get these next two terms
1750 - 60 = 1690
1690 - 60 = 1630
which are the two answers
-----------
If you want to use a formula, then a1 = 2050 is the first term and d = -60 is the common difference. We get this nth term formula
a(n) = a1 + d(n-1)
a(n) = 2050 + (-60)(n-1)
a(n) = 2050 - 60n + 60
a(n) = -60n + 2110
Then note that six terms of the sequence are given to us. This means we want to find the 7th term, so we plug in n = 7 to get
a(n) = -60n + 2110
a(7) = -60(7) + 2110
a(7) = -420 + 2110
a(7) = 1690
The 7th term is 1690
Repeat for n = 8
a(n) = -60n + 2110
a(8) = -60(8) + 2110
a(8) = -480 + 2110
a(8) = 1630
The 8th term is 1630

Step-by-step explanation:
In a right angled triangle: the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)
64 + 64 = [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 128
