A horse at rest takes 60 breaths every 5 minutes. At this rate, in how many
minutes would the horse take 300 breaths?
1. 12 minutes
2. 25 minutes
3. 240 minutes
4. 3,600 minutes
Answer:
The correct answer is B. 25 minutes.
Step-by-step explanation:
Here, we know that a horse takes 60 breaths every 5 minutes. We need to find how many minutes it takes a horse to take 300 breaks. First, let's see how many times 60 can go into 300.
300 ÷ 60 = 5
Now, let's multiply this by 5.
5 x 5 = 25
Therefore, the answer is B. 25 minutes.
Hope this helps! :)

IN THE FIGURE 5.24 TO THE RIGHT ABCD IS A RHOMBUS.SHOW THAT AC IS THE BISECTOR OF <BAD.
In any rhombus, the four sides are the same length.
Because of this, we know that
AD = ABCD = BCFurthermore, AC = AC due to the reflective property
Those three facts then allow us to prove triangle ACD is congruent to triangle ACB through the SSS congruence property. Then from CPCTC, we then know that angle DAC = angle BAC, which is enough to show that AC bisects the angle shown. The term "bisect" means "cut in half".
fill in the blank to show an example of the symmetric property:

Solve the equation 8(3x - 6) = 6(4x + 8). Does the equation have one solution, no solution, or infinitely many solutions? Explain. ( worth two point, answer and explanation)
⠀⠀⠀⠀
Equation have No solutions
⠀⠀⠀⠀
______________________
⠀⠀⠀⠀
➤ How to solve ?⠀⠀⠀⠀
For solving such problems we need to recall equations .
⠀⠀⠀⠀
When the value of two variable comes equal and zero in an equation then that equation is said to have infinitely many solutions . If the value of a variable have any particular constant then the equation is said to have one solution . If the value of of any variable comes undefine then the equation is said to have no solution .
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
⠀⠀⠀⠀
SolutiOn :➠ 8( 3x - 6 ) = 6(4x + 8 )
➠ 24x - 48 = 24x + 48
Now, we will bring the variable on left hand side and constants on right hand side
➠ 24x - 24x = 48 + 48
➠ 0 = 48 + 48
➠ 0 = 96
As we can see the equation have end with a undefined value the equation have no solutions
➠ No Solutions

The average daily maximum temperature in Cyprus is 21.85 degrees Celsius in the average daily minimum temperature is -4.7 degrees Celsius is the average daily maximum temperature is blank Celsius higher than the average daily minimum temperature
Answer:
26.55°C
Step-by-step explanation:
21.85 + 4.7
Average maximum daily temperature = 21.85°C
Average minimum temperature = - 4.7°C
The average daily maximum temperature is x°C higher than the average daily minimum temperature ;
x = (maximum temperature - minimum temperature)
x = (21.85 - (-4.7))°C
x = (21.85 + 4.7)°C
x = 26.55°C
Hence, The average daily maximum temperature is 26.55°C higher than the average daily minimum temperature

O yes, because all the elements of set A are in set R
O yes, because all the elements of set R are in setA
O no, because each element in set A is not represented in set R
O no, because each element in set R is not represented in set A
Answer: BBBBBB
Step-by-step explanation:
The correct option is,
"Yes because all the elements of set R are in set A"
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given the following sets;
U = {x | x is a real number}
A = {x | x is an odd integer}
R = {x | x = 3, 7, 11, 27}
Hence, The elements of the set A are,
⇒ A = {1, 3, 5, 7, 9, 11...}
R ⊂ A can be interpreted as R is a subset of A
i.e all the elements of R can be found in A.
Since, all the elements of R are all odd integers and can be fi=ound in A, hence R ⊂ A is TRUE.
The correct option is "Yes because all the elements of set R are in set A"

Write the first five terms in the arithmetic sequence. f(n + 1) = f(n) – 19, f(1) = 34
Answer:
34, 15, -4, -23 and -42
Step-by-step explanation:
We are to find the first five sequence
when n = 1
f(2) = f(1) - 19
f(2) = 34 - 19
f(2) = 15
when n = 2
f(2+1) = f(2) - 19
f(3) = f(2) - 19
f(3) = 15 - 19
f(3) = -4
when n = 3
f(3+1) = f(3) - 19
f(4) = f(3) - 19
f(4) = -4 - 19
f(4) = -23
when n = 4
f(4+1) = f(4) - 19
f(5) = f(4) - 19
f(5) = -23 - 19
f(5) = -42
Hence the first five terms in the arithmetic sequence are 34, 15, -4, -23 and -42
Dylan has a bank that sorts coins as they are dropped into it. A panel on the front displays the total number of coins inside as well as the total value of these coins. The panel shows 90 coins with a value of $17.55 inside of the bank. Dylan only collects dimes and quarters. Determine how many quarters and how many dimes Dylan has.
Answer: There are 57 quarters and 33 dimes.
Step-by-step explanation:
let x = Number of quarters
y= Number of dimes
As per given , we have
x+y = 90 (i)
0.25x+0.10y= 17.55 (ii)
Multiply 10 on both sides of (ii)
2.5x+y= 175.5 (iii)
Eliminate (i) from (iii) , we get
1.5x = 85.5
⇒ x= 57
Put value of x in (i) , we get
57+y=90
⇒ y= 90-57
⇒ y= 33
Hence, there are 57 quarters and 33 dimes.
