Swimmers best time in event is 53.87 seconds. On average, his best time decreases by 0.28 seconds each of the next five times he swims the event. Does he accomplish his goal of swimming the event in less than 52.5 seconds?
Answer: Yes. This is because his fifth attempt was 52.47 seconds
Step-by-step explanation:
From the question, we are informed that Swimmers best time in event is 53.87 seconds and that on average, his best time decreases by 0.28 seconds each of the next five times he swims the event.
The time for the fifth time he swim will be:
= 53.87 - 5(0.28)
= 53.87 - 1.4
= 52.47 seconds
This means that he accomplish his goal of swimming the event in less than 52.5 seconds.

A firefighter climbed up to the middle of a ladder to see if there was any fire on the second floor of a building and there was none; he then climbed up 10 more steps and saw some smoke so he came back down 14 steps and waited for 5 seconds to check his equipment. He then climbed 20 steps all the way to the top of the ladder and got off on the roof. How many steps are there on the ladder?
Answer:
32
Step-by-step explanation:
Let there be n number of steps on the ladder.
First, the firefighter climbed up to the middle of a ladder. so to reach the middle of the ladder he must have climbed [tex]\frac n 2[/tex] steps.
Then, after climbed 10 more steps, the total number of stairs from the ground he climbed [tex]= \frac n 2 +10[/tex].
Then, he came back down 14 steps, so the total number of stairs from the ground he climbed [tex]= \frac n 2 +10 -14=\frac n 2 -4[/tex].
Remaining steps [tex]= n - \left(\frac n 2 -4 \right)=\frac n 2 +4[/tex]
Given that he climbed 20 steps all the way to the top of the ladder which is equal to the remaining steps. So,
[tex]\frac n 2 +4 = 20[/tex]
[tex]\Rightarrow \frac n 2 = 20-4=16[/tex]
[tex]\Rightarrow n = 16 \times 2 = 32.[/tex]
Hence, there are 32 steps on the ladder.

how do you find areas of shapes
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

6. Kiera is comparing the cost of two swimming pool memberships to determine which she will buy. Pool K charges a $30 membership fee plus $5 per visit. Pool M charges a $10 membership fee plus $10 for every two visits. Part A. For each pool, write an equation that represents C, the total cost for n visits. Identify the slope and intercept of each equation.
Answer:
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
Step-by-step explanation:
Total cost [Pool] = Fixed (membership) cost + Variable cost (per visit)
Intercept is part at which equation line intersects x or y axis. In pools case, it is fixed (membership) cost. Slope is change in y due to change in x. In pools case, it is variable cost (per visit)
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
where V = number of visits.
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
What is the value of x in the equation. 1/2x - 3/4 = 3/8 - 5/8x?
Answer:
x=1
Step-by-step explanation:
simplify and create a chart of denominators until you find the common one.
Answer:
Step-by-step explanation:
1/2x - 3/4 = 3/8 - 5/8x
+ 5/8x + 5/8x
9/8x - 3/4 = 3/8
+ 3/4 + 3/4
9/8x = 9/8
divide both sides by 9/8
x = 1

Write an equation in Slope Intercept Form for the following line.
Answer:
y=2x+-4
Step-by-step explanation:
Answer:
The equation in slope intercept form (y = mx + b) is y = 2x - 4
m = the slope
b = the y intercept
The line cross the y-axis at -4 so the y-intercept (b) is -4.
You can use the slope formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.
[tex]\frac{0--4}{2-0}[/tex] = [tex]\frac{4}{2}[/tex] = 2
So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

An astronaut weighs 168 lbs on earth and 28 lbs on the moon. Kristine weighs 108 lbs on earth. How would Kristine find out how much she would weigh on the moon? F divide 168 by 28 and divide 108 by the answer G subtract 28 from 168 and subtract that amount from 108 H divide 168 by 108 and multiply the result by 28 J subtract 108 from 168 and divide by 28
Answer: F divide 168 by 28 and divide 108 by the answer
Step-by-step explanation:
From the question, we are informed that an astronaut weighs 168 lbs on earth and 28 lbs on the moon. We are further told that Kristine weighs 108 lbs on earth.
To find out the weight of Kristine on the moon, we divide 168 by 28 and divide 108 by the answer. This will be:
= 168/28 = 6
We then divide 108 by 6. This will be:
= 108/6
= 18
Kristine weight on the moon is 18lbs

The average person uses 6 square feet of area. If we have a 30 ft by 15 ft room with walls 10 ft high, approximately how many people could stand up in the room?
Answer:
300persons
Step-by-step explanation:
First we need to find the total surface area of the room expressed as;
Total surface area = 2(LW+LH+WH)
L is the length = 30ft
W is the width = 15ft
H I the height = 10ft
Substitute
TSA = 2{(30(15)+30(10)+15(10)}
TSA = 2(450+300+150)
TSA = 2(900)
TSA = 1800ft²
Since an average person uses 6 square feet of area, the total numwr of people that can stand up the room is expressed as;
Total people = TSA/average area per person
Total person =1800/6
Total person = 300persons
Hence 300persos can stand up the room
