Answer:
55 push ups
Step-by-step explanation:
Given that:
Starting count = 10
Additional count = 3
Starting count + (additional count * number of days)
Exactly on the 3rd week = on the 15th day
10 + (3 * 15)
10 + 45
= 55 push ups

2. Suppose there are 6 million people in New York City that walk an average of 2.5 miles per day. If we add up all the miles walked by these 6 million how many times around the Earth would these walkers have gone? Assume the distance around the Earth is 2.5 * 10 ^ 4 miles. Write your result in scientific notation.
Answer:
600 timesStep-by-step explanation:
GivenNumber of people:
6 million = 6*10^6Distance to walk:
2.5 miles per day per personDistance around the Earth
2.5*10^4SolutionTotal distance walked:
6*10^6*2.5 = 15*10^6The ratio of total distance to the distance around the Earth:
15*10^6 / 2.5*10^4 = 6*10^2 = 600 timesNumber of people:
6 million = [tex]6[/tex] × [tex]10^{6}[/tex]
Distance to walk:
2.5 miles every day per person
Distance around the Earth
[tex]2.5[/tex] ×[tex]10^{4}[/tex]
Total distance walked:
[tex]6[/tex] × [tex]10^{6}[/tex] × [tex]2.5[/tex] [tex]= 15[/tex] × [tex]10^{6}[/tex]
The ratio of total distance to the distance around the Earth:
[tex]15[/tex] × [tex]10^{6}[/tex] / [tex]2.5[/tex] × [tex]10^{4}[/tex] = [tex]6[/tex] × [tex]10^{2}[/tex] = [tex]600[/tex]
In a polar coordinate system, the midpoint of the line segment whose endpoints are $\left( 8, \frac{5 \pi}{12} \right)$ and $\left( 8, -\frac{3 \pi}{12} \right)$ is the point $(r, \theta).$ Enter $(r, \theta),$ where $r > 0$ and $0 \le \theta < 2 \pi.$
Answer:
Step-by-step explanation:
Given the coordinate points (8, 5π/12) and (-3, π/12)
The midpoint is expressed using the formula
M(X,Y) = {(x1+x2)/2, (,y1+y2)/2}
X = x1+x2/2
X = 8-3/2
X = 5/2
Y = y1+y2/2
Y = (5π/12+π/12)/2
Y = (6π/12)/2
Y = 6π/24
Y = π/4
Hence the required coordinate is at(2.5, π/4)
If a water park sold 170 tickets and 30% of them were adult tickets, how many tickets did they sell that were not for adults?
119 tickets
have a good day
Answer:
30% of 170 is 51, so 51 adult tickets were sold. Now, we subtract that from 170 . to get 119. 119 were not adults

At 9:00 a.m., the wind speed at Harbor Bay was recorded. After that, the wind speed was recorded every hour. Each measurement showed an increase in wind speed of 3 miles per hour. The strongest wind was recorded at 4:00 p.m., and measured 52 miles per hour. After that, the wind speeds started to decrease. How windy was it when the experiment began?
Answer:
The wind speed was 31 miles per hour when the experiment began.
Step-by-step explanation:
Linear Dependency
The wind speed is known to increase at a rate of 3 miles per hour every hour.
From 9:00 a.m. to 4:00 p.m. there are 7 hours.
Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.
Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:
52 miles / hour - 21 miles / hour = 31 miles / hour
The wind speed was 31 miles per hour when the experiment began.
Answer:
The wind speed was 31 miles per hour when the experiment began.

HELP PLZ
The kingdom of Arendelle is trying to decide who to send to the regional track meet. Anna, Elsa, and Olaf competed in the long jump and their 6 jumps are shown below (in meters). Kristoff says that Olaf has the longest average, so he should be sent to the track meet. Do you agree or disagree? Why?
Please find table attached
Answer:
Agree: Olaf should be sent to the track meet because he has the longest average
Step-by-step explanation:
To ascertain if this is true, we must calculate the average for each athlete
Mean or average of athlete= total score of jumps/ number of jumps
Average for Anna= 3.25+3.95+4.28+2.95+3.66+3.81/6 = 3.65
Average for Elsa=3.55+3.88+3.61+3.97+3.75+3.59/6
=3.725
Average for Olaf=3.67+3.78+3.92+3.62+3.85+3.73/6
= 3.76
Therefore Olaf has the longest average =3.76

Evaluate the following expression when X = -4 X to the power of 2 +2x-9
Answer:
-1
Step-by-step explanation:
X = -4
so x^2+ 2x -9 = (-4)^2 + 2*(-4) - 9
= 16 - 8-9
= 8-9
= -1

A pizzeria sells a round pizza with a diameter of 16 inches.
Another pizzeria sells a large square pizza with a side length of 15 inches
Which has more crust along the outside edge of the pizza, the round pizza or the square pizza?
Answer:
Square pizza
Step-by-step explanation:
d = Diameter of round pizza = 16 inches
a = Side length of square = 15 inches
More crust means the edge length of the pizza is greater. Edge length is given by the perimeter.
Circumference or perimeter of the round pizza
[tex]C=\pi d\\\Rightarrow C=\pi\times 16\\\Rightarrow C=50.27\ \text{inches}[/tex]
Perimeter of the square is
[tex]P=4a\\\Rightarrow P=4\times 15\\\Rightarrow P=60\ \text{inches}[/tex]
So, the square pizza has more crust compared to the round pizza.
EXPENSES: Camille has no more than $50.00 to spend each week for lunch and bus fare. Lunch costs $3.00 each day, and bus fare is $1.75 each ride. Write an inequality for this situation. Can Camille buy lunch 7 times and ride the bus 14 times in one week????
Answer:
Inequality: [tex]3.00 L + 1.75B \leq 50[/tex]
She can afford to buy the lunch and bus rides
Step-by-step explanation:
Given
[tex]Maximum\ Amount = \$50.00[/tex]
[tex]Lunch = \$3.00[/tex] daily
[tex]Bus\ Fare = \$1.75[/tex] daily
Solving (a) The inequality
Let bus ride be represented with B and Lunch be represented with L
If 1 bus ride costs $1.75, then
B bus ride would cost $1.75 * B
If 1 lunch costs $3.00, then
L lunch would cost $3.00 * L
Total Spending is then the sum of the above expression i.e.
$3.00 * L + $1.75 * B
The question says Camille can not spend more than $50.00.
This is represented by less than or equal to.
So, the expression is:
[tex]3.00 * L + 1.75 * B \leq 50[/tex]
[tex]3.00 L + 1.75B \leq 50[/tex]
Solving (b): Can she afford 7 lunch and 14 bus ride?
To do this, we simply substitute 7 for L and 14 for B
[tex]3.00 * 7 + 1.75 * 14 \leq 50[/tex]
[tex]21 + 24.5 \leq 50[/tex]
[tex]45.5 \leq 50[/tex]
The above inequality is true.
Hence, she can afford to buy the lunch and bus rides

4x-2=x+13
Solve for X
Show all steps
Answer:
x=5
Step-by-step explanation:
isolate the x on one side of the equal sign so move the 2 over by adding 2
4x=x+15 ( add 2 to both sides )
then move the x over
3x=15 ( subtract x from both sides )
then divide by 3
x=5
Answer: Hope it helps, have a nice day :)
x=5
Step-by-step explanation:
So you can only have x on one side, so first you move an x to the other side of the equal sign.
so, 4x-2=x+13, you can move either x, but I'm moving x instead of 4x
-x -x
Your new equation is 3x-2=13, because the x's cancel out
Then you add 2 on both sides 3x-2=13
+2 +2
___________
3x=15
then you divide by 3 on both sides
3x divided by three leaves x by itself, and 15 divided by three is 5.
3x=15
3 3
x=5

Answer:
A) y>=-1
Step-by-step explanation:
The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer
Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.
