It takes 165 minutes per week if 10% increase in volume for an exercising client.
How much is the 10% increase in the volume?A client is exercising for 150 minutes per week. I.e., 30 minutes, 5 days per week.
So, 10% increase results,
30 minutes × 10% = 3
So, the increased minutes per day = 30 + 3 = 33 minutes/day.
How many minutes total per week results if a 10% increase in the volume?After the 10% increase, the minutes per day = 33 minutes
Since 5 days a week, he does exercise, the total minutes per week
= 33 × 5 = 165 minutes.
So, a 10% increase in volume would result in 165 minutes total per week.

Which equation represents the temperature, t, at hour h?
OA. t= 2h+32
B. t= -2h+ 32
C. t = 32h-₂
OD. t= -32h+2
You would multiply the change per hour by number of hours to get -2h
That would be added to the starting temperature.

The point-slope form of the
equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = ~(x - 8). What is
the slope-intercept form of the
equation for this line?
y= ~x-12
y= =x-4
y=~x+2
V= x+6
Answer: y = -x + 2
Step-by-step explanation:
Point slope form is y - y = m(x - x)
m = the slope of the line
Slope-intercept form is y = mx + b
m = the slope of the line
b = y-intercept
So because the - is in the m spot in the point-slope form, that means that is the slope of the line meaning it will also be in the m spot in slope-intercept form. The y-intercept of the line is found when x is 0. When we look at the two coordinates provided you can see that one of them shows when x is 0. We see that when x is 0, y is 2 which means that the y-intercept is 2.
So when you put the 2 in place of b, you get y = -x + 2

Step-by-step explanation:
there's 12 red cards and 23 black cards
total = 35 cards
probability to pick a black card = 23/35
Answer: 23/35
Step-by-step explanation:
Probability is the measure of the likelihood of an event occurring. It is measured by the number of favorable outcomes over the total number of possible outcomes.
Here, the event is a black card being drawn. Since there are 12 + 23 = 35 cards in the deck, there are 35 possible outcomes of what card is picked. Out of those 35 cards, 23 are black, making 23 of the 35 options be the option we want.
23 black cards out of 35 total cards can also be written as [tex]\frac{23}{35}[/tex], which is the probability that a black card is chosen.
If a single 2 hp motor draws 13.8 amps on 115 volt ac current, how much current would 9 identical motors pull?
what is the answer and how do you solve it?
The current drawn by 9 identical motors will be 124.2 amps current
Current is the flow of electrical charge carriers like electrons. Current flows from negative to positive points. The SI unit for measuring electric current is the ampere (A). One ampere of current is defined as one coulomb of electrical charge moving past a unique point in a second.
since , one motor of 2hp draws = 13.8 amps current
hence , 9 identical motor will pull = 13.8 * 9 (each will pull same amount of current )
= 124.2 amps current
The current drawn by 9 identical motors will be 124.2 amps current

Matt's four cousins are coming to visit. There are four identical rooms that they can stay in. If any number of the cousins can stay in one room, how many different ways are there to put the cousins in the rooms
The total number of different ways there are to put the cousins in the rooms is; 15
How to use probability combinations?When we count the number of cousins staying in each room, it means that the possibilities are as follows; (4,0,0,0), (3,1,0,0), (2,2,0,0), (2,1,1,0), (1,1,1,1).
1) (4,0,0,0): This means that there is only 1 way to put all the cousins in the same room due to the fact that the rooms are identical.
2) (3,1,0,0): This means that there are 4 ways to choose which cousin will be in a different room than the others.
3) (2,2,0,0): This means that there are 3 ways to choose which of the other cousins will also stay in that room, and then the other two are automatically in the other room.
4) (2,1,1,0): This means that the number of ways to choose which cousins stay in the same room is; 4C2 = 6
5) (1,1,1,1): This means that there is only one way for all the cousins to the total number of possible arrangements is;
1 + 4 + 3 + 6 + 1 = 15each stay in a different room.
Therefore, the total number of possible arrangements is;

If x = the larger number and y = the smaller number, then which of the following is the value of the smaller number?
The larger number is 32 and the smaller number is 28 given that one number is 4 more than another and their sum is 60. This can be obtained by forming algebraic equation and finding
Calculate the value of the numbers:Given that one number is 4 more than another,
⇒x = y + 4 (equation (1))
Their sum is 60,
⇒x + y = 60
y + 4 + y = 60 (From (1))
2y + 4 = 60
2y = 56 ⇒ y = 28
x = y + 4 = 28 + 4 = 32

Mrs. Laura is between 50 and 80. If you divide her age by 9, the remainder is 1. If you divide by 4, the remainder is 1. How old is Mrs. Laura?
Answer: 73
Step-by-step explanation:
I think she's 73? You have to take multiples of nine and see if they work! I did 72 since I knew that 72 goes into 9 equally and if she is 73 there would be a remainder of 1. After that, I stuck with 73 and since I knew that 18 times 4 is also 72, I knew that 73 divided by 4 would give me 18 with a remainder of 1.
The solution is 37 years, that is, Mrs. Laura's age is 37 years old.
Given information in the problem:
1. Mrs. Laura's, L age is between 50 and 80.
2. When you divide age by 9, the remainder is 1.
3. When you divide age by 4, the remainder is also 1.
To find L exact age, start by checking multiples of 9 that leave a remainder of 1 when divided by 4:
9 × 1 + 1 = 10 (remainder of 1 when divided by 4)
9 × 2 + 1 = 19 (remainder of 1 when divided by 4)
9 × 3 + 1 = 28 (remainder of 1 when divided by 4)
9 × 4 + 1 = 37 (remainder of 1 when divided by 4)
9 × 5 + 1 = 46 (remainder of 2 when divided by 4)
9 × 6 + 1 = 55 (remainder of 3 when divided by 4)
9 × 7 + 1 = 64 (remainder of 0 when divided by 4)
Check multiples of 4 that leave a remainder of 1 when divided by 9:
4 × 1 + 1 = 5 (remainder of 1 when divided by 9)
4 × 2 + 1 = 9 (remainder of 1 when divided by 9)
4 × 3 + 1 = 13 (remainder of 4 when divided by 9)
4 × 4 + 1 = 17 (remainder of 8 when divided by 9)
From the above calculations, see that the only common number between the two sets of multiples is 37.
So, L's age is 37 years old.
