Answer:
400 passengers
Step-by-step explanation:
To solve the problem, a proportion would be best!
First, let's set up the left side of the proportion. Percents, when used in parts, are always part of 100%, making 100% a whole. We'll use both 10% and 100% as our first fraction, which should look something like this:
[tex]\frac{10p}{100w}[/tex] (with p standing for part and w standing for the whole)
Next, let's set up the right side of our proportion. We'll use the 40 for our part and x for our whole since that is the number we are solving for. The proportion should now look like this:
[tex]\frac{10p}{100w} = \frac{40p}{x}[/tex]
To solve, just cross multiply and divide! Multiply 40 by 100 to give you 4,000. Next, divide 4,000 by the remaining 10 to give you a final answer of 400. If 40 passengers on the flight are in first class, then there are 400 total passengers. Hope this helps!
Bobby bought a new tablet.He made an initial payment of $75 to the store, and he will pay $15 each month until the tablet is paid off. Witch equation represents the relationship between x, the number of monthly payments Bobby made, and y, the total amount that Bobby has paid at the store
Answer:
Step-by-step explanation:
Answer:
y=75+15m
Step-by-step explanation:
75 - initial payment
15m - 15 dollars payed each month (m)
8. Determine whether the triangles are similar. If so, write a similarity
statement and the postulate or theorem that justifies your answer.
Answer:
Option (4)
Step-by-step explanation:
If ΔLMN is similar to ΔQRS,
Their corresponding sides will be proportional.
[tex]\frac{LM}{QR}= \frac{MN}{RS}= \frac{LN}{QS}[/tex]
[tex]\frac{5}{6}= \frac{3}{4}= \frac{6}{7}[/tex]
But it's not true.
Therefore, the given triangles ΔLMN and ΔQRS are not similar.
Option (4) will be the answer.

John rolls a number cube labeled 1-6 and flips a coin. What is the
probability of rolling a 5 and landing on Heads?
The probability of rolling a 5 for John is 16.666 percent. Because there is 5 other numbers , it is possible but you would have to add all numbers together and then divide it with 100 cause that’s will be how much the percent would be. So you would divide 100 with 6 and then the answer is 16.666 which is also the percentage for John to roll the dice and get a 5.

Which expression is equivalent to
-4(h - 2) + 20
a. -4h + 12
b. -4h + 18
c. -4h + 28
d. -4h + 22
Answer:
C.
Step-by-step explanation:
it would simplify to -4h+8+20
then if you gather like terms it would be -4h+28

solve 3x^3 +2x^2 +15 divided by (x+2) show step by step
Answer:
3x^2-4x+8 (R -1)
Step-by-step explanation:
We can use synthetic division:
-2 | 3 2 0 15
____-6 8 -16
3 -4 8 | -1
So basically, you solve x+2=0 (which is x=-2) and then you put it on the left side. Then make a line and put the coefficients of the polynomial you want to divide. Then with the first coefficient it gets dropped. You would then multiply this by -2 (so 3*-2=-6) and then combine it with 2 in the second column (2+-6=-4). Then we do the same thing with the third column (-4*-2=8) and combine (0+8=8). Same with the fourth column (8*-2=-16) but when we combine this time the answer will be our remainder (15+-16=-1).
So how you would read your final answer is 3x^2-4x+8 (R -1) which the numbers you get are the coefficients.

Explain how 32
Divided 4 can help you solve
320 divided 4?
Answer/Step-by-step explanation:
Since 320 is 10 times 32. The answer for 320 divided by 4 is going to be 10 times the answer of 32 divided by 4.
320 ÷ 4 = 80
32 ÷ 4 = 8
As 320 is 10 times of 32 then values results also 10 times.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
Given:
We have to divide 32 by 4.
The division is as follow:
= 32/4
= (4 x 8)/ 4
= 8
If we multiply 10 to 32 then we get 320.
Then, if we multiply 10 to 8 we get
= 10 x 8
= 80

a) Write the sequence of natural numbers which are multiplied by 3 ?
b) Write the sequence of natural numbers which are multiplied by 3 and added to 1 ?
c) Check whether the sequence obtained above is an arithmetic sequence or not?
Answer:
a) 3, 6, 9, 12, 15,...,[tex]3\cdot n[/tex], b) 4, 7, 10, 13, 16,...,[tex]3\cdot n +1[/tex], c) Both sequences are arithmetic.
Step-by-step explanation:
a) The sequence of natural numbers which are multiplied by 3 are represented by the function [tex]f(n) = 3\cdot n[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 3, 6, 9, 12, 15,...
b) The sequence of natural numbers which are multiplied by 3 and added to 1 is represented by the function [tex]f(n) = 3\cdot n + 1[/tex], [tex]n\in \mathbb{N}[/tex]. Let see the first five elements of the sequence: 4, 7, 10, 13, 16,...
c) Both sequences since differences between consecutive elements is constant. Let prove this statement:
(i) [tex]f(n) = 3\cdot n[/tex]
[tex]\Delta f = f(n+1) -f(n)[/tex]
[tex]\Delta f = 3\cdot (n+1) -3\cdot n[/tex]
[tex]\Delta f = 3[/tex]
(ii) [tex]f(n) = 3\cdot n +1[/tex]
[tex]\Delta f = f(n+1)-f(n)[/tex]
[tex]\Delta f = [3\cdot (n+1)+1]-(3\cdot n+1)[/tex]
[tex]\Delta f = 3[/tex]
Both sequences are arithmetic.

2. Last year Kellog decided to reduce the size of packaging in order to raise 1 p the price per ounce. If the original size of the box was 18 oz and Kellog reduced the size of the packaging by 15%. How many oz can the new box hold?
Answer:
15.3 oz
Step-by-step explanation:
Here, we want to get the value of the new size after reduction
We start with reduction amount
That will be;
15/100 * 18 = 2.7 oz
So we now get what it can hold
That’s;
18-2.7 = 15.3 oz

the change in altitude of a bird after 2 1/2 seconds was -41 1/4 feet. what was the average change in altitude of the bird in feet per second
PLEASE HELP
Answer:
-16¹/₂ feet per second
Step-by-step explanation:
average change in altitude in feet per second = change in altitude in feet/change in time in seconds
= -41¹/₄ ft ÷ 2¹/₂ s
= -165/4 ft ÷ 5/2 s
= -165/4 × 2/5 ft/s
= -33/2 feet per second
