Answer:
21 cm
Step-by-step explanation:
The two pieces have a length ratio of 1 : 4, so the shorter piece is 1/(1+4) = 1/5 of the total length.
105 cm/5 = 21 cm
The shorter piece is 21 cm.

A scientist studied the migration patterns of two types of whales. The humpback whale traveled 2,000 miles in 25 days. The gray whale traveled 2,250 miles in 30 days. Assuming the humpback whale travels the same distance each day, what is the unit rate for the humpback whale in miles per day?
Answer:
it is 80 miles
Step-by-step explanation:
2000 divided by 25 is 80 therefore you multiply 80 x 30
Find two consecutive odd numbers such that the sum of the larger number and twice the smaller number is 27 less then foir times the smaller number
Answer:
29 and 31Step-by-step explanation:
x - some integer
2x+1 - an odd integer (the smaller one)
2x+1+2=2x+3 - the next odd integer consecutive to 2x+1 (the larger)
2×(2x+1) - twice the smaller number
2x+3+2•(2x+1) -the sum of the larger number and twice the smaller number
4•(2x+1) - four times the smaller number
4•(2x+1)-27 - 27 less then four times the smaller number
2x + 3 + 2•(2x + 1) = 4•(2x + 1) - 27
2x + 3 + 4x + 2 = 8x + 4 - 27
6x + 5 = 8x - 23
-5 -5
6x = 8x - 28
-8x -8x
-2x = - 28
÷(-2) ÷(-2)
x = 14
2x+1 = 2•14 + 1 = 29
2x+3 = 2•14 + 3 = 31
Check: 31+2•29=31+58=89; 4•29-27=116-27=89

Answer:
It would be A.
Step-by-step explanation:
You can simply add the numbers to coordinates to see if matches.
For example, if you add the x + 2 to -3 and 2, its -1 and 4. Then if you add y+3 to -1 and 1, it's 2 and 4. I hope that makes sense :)
At the beginning of the business day, a bank's vault held $575,900. By the end of the day, $(3.5 103) had been added to the vault. How much money did the banks vault hold at the end of the business day write ur answer in standard form
3.5*10^3=3,500
3,500+ 575,900=579,400
The bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.
What are integers?An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Now it is given that,
Money in the bank vault at the beginning of the day = $575,900
Money added in the vault at the end of the day = $3.5 x 10^3 = $3,500
Since money is added in the vault thus it is gain.
So, Money added in the vault at the end of the day = + $3,500
Thus, Money at the end of the business day = $575,900 + $3,500 = $579,400
Thus, the bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.

C is the biggest number, so put in all the numbers in the equation then if it's equal then it's a right triangle.
example: 6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
this one is a right angle because the two sides is equal to the hypotenuse(largest number).

The price of a car has been reduced from $22,500 to $16,650. What is the percentage decrease of the price of the car?
Answer:
26%
Step-by-step explanation:
$22,500-$16,650= $5,850
I started by multiplying buy 0.20 from $22,500 and then Jumped to 0.25% and when I realized i was close I multiplied $22,500 *0.26 and matched the decreasing price of $5,850.
$22,500*0.20 = $4,500 off
$22,500*0.25 = $5,625 off
$22,500*0.26 = $5,850 off

Inspectors for a hospital chain with multiple locations randomly select some of their locations for a cleanliness check of their operating rooms. The inspectors check every operating room in the hospitals that were chosen. What sampling method was used?
Answer:
Cluster Random Sample
Step-by-step explanation:
The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.
Sampling method is the method where the subset of an overall population is selected.
The sampling method used was cluster sampling
From the question, we understand that:
The inspectors select some locationsThen all selected locations was checkedThe above illustrates cluster sampling.
This is so because, cluster sampling involves breaking down a population into smaller size.
In this case, the smaller size are the locations that were selected.

reduce [tex]\frac{54}{81}[/tex]
Answer:
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Step-by-step explanation:
Fraction Reduction
To reduce a fraction, we try to divide both the numerator and denominator by the very same number until no more numbers can be found.
The fraction to reduce is:
[tex]\displaystyle \frac{54}{81}[/tex]
Since the denominator is odd, we cannot divide by 2, but we can divide by 3:
[tex]\displaystyle \frac{54}{81}=\frac{18}{27}[/tex]
We divide by 3 again:
[tex]\displaystyle \frac{18}{27}=\frac{6}{9}[/tex]
We divide by 3 one last time:

Elise says, "If you subtract 13 from my number and multiply the difference by -6, the result is -60 ." What is 's number?
please help will give brainiest!
Answer:
n = 23
Step-by-step explanation:
n - 13 x -6 = -60
distribute:
(n x -6) - (13 x -6) = -60
-6n - (-78) = -60
two negatives in front of a number makes it a positive number
so rewrite -6n + 78 = -60
-6n = -60 - 78
-6n = -138
n = [tex]\frac{-138}{-6}[/tex]
