The equation for the number of beats per minute is 55 beats per minute
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of beats be = A
Now , the value of A = 220 beats
The total time required for Sam to have 220 beats = 4 minutes
So , the number of beats of Sam in 1 minutes is calculated by
The equation will be
The number of beats of Sam in 1 minutes is = total number of beats / total time required for Sam to have 220 beats
The number of beats of Sam in 1 minute is = 220 / 4
The number of beats of Sam in 1 minute is = 55 beats per minute
Therefore , Sam would have 55 beats every minute or 55 beats per minute
And for the period of 4 minutes , Sam would have
Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4
Number of beats for 4 minutes = 55 x 4
Number of beats for 4 minutes = 220 beats in 4 minutes
Hence , The equation for the number of beats per minute is 55 beats per minute

The average winter temperature at the South Pole is -49 degrees Celsius. The coldest temperature recorded in Antarctica was 40.6 degrees Celsius colder than the average winter temperature at the South Pole. What was the coldest recorded temperature in Antarctica?
Answer:
The coldest temperature at Antarctica is -89.6 degrees celsius
Step-by-step explanation:
Here, we are interested in calculating the coldest temperature in Antarctica.
In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.
The average winter temperature at south pole = -49 degree celsius
The coldest temperature is thus -49-40.6 = -89.6 degrees celsius

g(x) = 2x^2 - 4x
h(x) = x^2 - x + 7
Find f[g(5)]
A. 92
B. 2
C. 30
D. 242
Answer:
A
Step-by-step explanation:
Evaluate g(5), then use the value obtained to evaluate f(x) , that is
g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then
f(30) = 3(30) + 2 = 90 + 2 = 92

Find the distance between the two points in simplest radical form.
(0, –4) and (-3,-1)
Answer:
3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (- 3, - 1)
d = [tex]\sqrt{(-3-0)^2+(-1+4)^2}[/tex]
= [tex]\sqrt{(-3)^2+3^2}[/tex]
= [tex]\sqrt{9+9}[/tex]
= [tex]\sqrt{18}[/tex]
= [tex]\sqrt{9(2)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Hey there!
Given;
The points are;(0,-4) and (-3,-1).
Use formula for distance between the two points.
[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
Put all values.
[tex]d = \sqrt{( { - 3 - 0)}^{2} + ( { - 1 + 4)}^{2} } [/tex]
Simplify to get answer.
[tex]d = \sqrt{9 + 9} [/tex]
[tex]d = \sqrt{18} [/tex]
[tex]d = 3 \sqrt{2} [/tex]
Therefore, the distance is 3√(2) units or 4.24 units.

Explanation:
Replace every x with -3
Then use the order of operations (PEMDAS) to simplify
y = -2x^2 + x - 5
y = -2(-3)^2 + (-3) - 5 ... x replaced with -3
y = -2(9) - 3 - 5
y = -18 - 3 - 5
y = -21 - 5
y = -26
Answer:
-26
Step-by-step explanation:
1. plug in -3 for all x's
-2(-3)^2 + (-3) -5
2. combine like terms
-2(-3)^2 - 8
3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)
-2(9) - 8
4. peMdas. multiply -2 and 9 next.
-18 - 8
5. pemdaS. subtract 8 from -18.
-18 - 8 = -26

In class of 60 boys, there are 45 boys who play card and 30 boys who play carom. How many play both games
Answer:
the answer is 40 boys
Step-by-step explanation:
Let's say there are x boys who play both cards and carrom.
We setup up an equation that involved all information given and x.
Boys who only play cards = 45-x
Boys who only play carrom = 20-x
Boys who play both = x
Add there together and you should get 60, which is the total number of students in the class.
(45-x)+(20-x)+x=60
65-x=60
x=5
Boys who only play cards=45-x=45–5=40
hope it helps you
Answer:
there are 15 boys who can play both games in the class.

Answer:
they won 52 games
they lost 19 games
the equation is 2x + 33= 71
Step-by-step explanation:
they played 71 games in total
say the amount of games they won is y
say the amount of games they lost is x
using the variables, you can form this equation:
y + x = 71
you also know that they won 33 more games then they lost.
so, y = x + 33
now, you can substitute y for x + 33 in the original equation
x + x + 33 = 71
combine like terms
2x + 33 = 71
subtract 33 from both sides of the equation
2x + 33 - 33 = 71 - 33
2x = 71 - 33
2x = 38
divide both sides of the equation by 2
2x/2 = 38/2
x = 38/2
x = 19
they lost 19 games.
now substitute 19 for x in the equation
y = x + 33
y = 19 + 33
y = 52
they won 52 games
