7:40pm------What is 89 minutes more? (What time will it be?)
The current time is 08 : 09 pm
How to determine the current time?The given parameters are
Time = 7 : 40 pm
Minutes added = 89 minutes
The current time is calculated as
Current time = Time + Minutes added
So, we have
Current time = 7 : 40 pm + 89 minutes
Evaluate the sum
Current time = 7 : 129 pm
Rewrite properly as
Current time = 08 : 09 pm
Hence, the current time is 08 : 09 pm

if w≠0, what is the additive inverse of the expression -3/w
The additive inverse of the expression -3/w is 3/w.
A number is known as the additive inverse of another, if the sum of the two numbers comes out to be zero. For example- given a number 3, its additive inverse will be -3, as 3 + (-3) = 0. The additive inverse of 0 is 0 itself.
Here, we are given an expression -3/w, such that w ≠ 0
Let us assume that the additive inverse of -3/w is x
Then, the sum of -3/w and x must be equal to zero
⇒ -3/w + x = 0
adding 3/w to both sides
⇒ x = 3/w
Thus, the additive inverse of -3/w is 3/w.

Mai-Lin measures her heart rate whenever she exercises and tries to make sure that she is staying in her target heart rate zone. The American Heart Association suggests a target heart rate of T=0.75(220-a), where T is a person's target heart rate and a is his or her age.
b. If Mai-Lin's target heart rate is 153, then how old is she? What property justifies your calculation?
When Mai-Lin's target heart rate is 153, then her age is 16 years.
How to illustrate the function?From the information, the The American Heart Association suggests a target heart rate of T=0.75(220-a),
where T = person's target heart rate
a = his or her age.
Therefore, when the heart rate is 153, the age will be:
T = 0.75(220 - a)
153 = 165 - 0.75a
0.75a = 165 - 153
0.75a = 12
Divide
a = 12/0.75
a = 16
The person's age is 16 years.

Ysau paints the back of an airplane hangar that is in the shape of a semicircle on top of a rectangle. Determine the approximate area that Ysau paints. I 24 ft 12 ft
Answer:
Step-by-step explanation:
Based on the dimensions of the semicircle and the rectangle, the approximate area that Ysau paints is 514 ft²
What area did Ysau paint?First, find the area of the rectangle:
= 24 x 12
= 288 ft²
The area of the semi-circle is the area of a circle divided by two. The radius is half of the longer side of the rectangle:
= 24 / 2
= 12 ft
Area of the semicircle is:
= (22/7 x 12 x 12) / 2
= 226 ft²
The total approximate area is:
= 226 + 288
= 514 ft²

10 juniors prefer tea.
There are no adult members who prefer

2 out of the 18 juniors prefer coffee.
4 out of the 28 members who prefer tea
are seniors.
What fraction of members in the club
prefer hot chocolate?
Give your answer as a fraction in its
simplest form.
Fraction of members in the club that prefer hot chocolate = [tex]\frac{7}{40}[/tex]
It's Given that :
A sports club has 80 participants.
Senior Members = 25
Junior Members = 18
Adult Members = 80 - (25 + 18) = 80 - 43 = 37
JUNIOR MEMBERS :
Prefers tea = 10
Prefers Coffee = 2
Prefers hot chocolate = 18 - (10 + 2) = 18 - 12 = 6
SENIOR MEMBERS :
Prefers tea = 4
Prefers coffee = 13
Prefers hot chocolate = 25 - (4 + 13) = 25 - 17 = 8
ADULT MEMBERS :
Prefers tea = 28 - (10 + 4) = 28 - 14 = 14
Prefers coffee = 37 - 14 = 23
Prefers hot chocolate = 0 (none)
Calculation of Fraction of members in the club that prefer hot chocolate = 8 + 6 = 14 members out of 80 members
= [tex]\frac{14}{80} = \frac{7}{40}[/tex]
Therefore 7 / 40 of members prefer hot chocolate.

X-values must be chosen and entered into the equation in order to graph a function. You will obtain a y-value once those values have been entered into the equation. A single point's coordinates are made up of its x and y values.
From the given question we can get:
A = 10 ₊ 20t
W = 30 ₊ 15t
Graph the each function to get the number of days.
A function can only be graphed if X-values are selected and put into the equation. Once those values are introduced into the equation, a y-value will be produced. The values of x and y are the coordinates of a single point.
Hence we get the number of days as 4. and the graph is attached below.

Find the indicated one-sided limits, if they exist. (if an answer does not exist, enter dne.)
The limit doesn't exist.
What is a limit?
The value that a function (or sequence) approaches when the input (or index) gets closer to a particular value is known as a limit. Calculus and mathematical analysis are impossible without limits, which are also required to determine continuity, derivatives, and integrals.
In addition to being closely related to limit and direct limit in category theory, the idea of a limit of a sequence is further generalized to include the concept of a limit of a topological net.
A function's limit is typically expressed in formulas as
[tex]\lim_{x \to c } F(x) = L[/tex]
It is typically used to assign values to specific functions at locations where none are defined while maintaining consistency with existing values.
[tex]F(x) = -x+8 ,x\leq 0[/tex]
[tex]F(x) = 4x+9 , if x > 0[/tex]
[tex]\lim_{x \to 0^{+} } F(x) = \lim_{n \to 0^{+} } (4x+9) = 9[/tex]
[tex]\lim_{x \to 0^{-} } F(x) = \lim_{x \to 0^{-} } (-x+8) =8[/tex]
[tex]\lim_{x \to 0^{+} } F(x) \neq \lim_{x \to 0^{-} } F(x)[/tex]

Values at one, two and three standard deviations are 77.9, 82.8 and 87.7 respectively. Values at -1, -2 and -3 standard deviations are 68.1, 63.2 and 58.3 respectively.
The average grade given = 73
So, the mean, μ = 73
The standard deviation, σ = 4.9
We need to find the 1,2 and 3 standard deviations and -1, -2 and -3 deviations from the mean.
We use the formula z = μ + nσ to find the values at nth deviations.
When n = 1
z = 73 + 1 x 4.9 = 77.9
When n = 2
z = 73 + 2 x 4.9 = 82.8
When n = 3
z = 73 + 3 x 4.9 = 87.7
When n = -1
z = 73 -1 x 4.9 = 68.1
When n = -2
z = 73 - 2 x 4.9 = 63.2
When n = -3
z = 73 - 3 x 4.9 = 58.3

Let the amount of pure antifreeze required be x + 10 liters. Thus, total solution amount will be
0.30 (10) + 1.00(x) = 0.50 ( x + 10 )
