Each week as part of her workout, Monica walks 0.5 mile, runs 1.6 miles, and then walks 0.75 mile.
How many total miles will Monica walk and run in a year? Reminder: there are 52 weeks in a year.
Answer:
She will walk and run 148.2 miles in a year
Step-by-step explanation:
She walks: 0.75+0.5=1.25 miles each week
And: 1.25 *52=65 miles a year
She runs : 1.6 miles a week
And: 1.6*52 =83.2 miles a year
Total miles : 83.2+65=148.2 miles
5. Jane can paint the office by herself in 7 hours. Working with an associate, she can paint the office in 3 hours. How long would it take her associate to do it working alone?
Answer:
5.3 hours
Step-by-step explanation:
Jane can paint the office by herself in 7 hours.
with an associate, she can paint the office in 3 hours.
The combined work rate is 3 hours per office
Required
the work rate for the associate
Step two:
let the expression for the wok rate be
1/A+1/B= 1/T
1/7+1/B=1/3
1/B=1/3-1/7
1/B= 8-4/21
1/B= 4/21
B= 21/4
B=5.3 hours
the work rate for the associate is 5.3 hours

The distance (in meters) at which a car needs to stop is equal to 4 times the square root of the speed of the car (in meters per second) when the driver
applies the brake A car is travelling 9 meters per second What is the distance at which the car will stop when the driver applies the brake
Answer:
12 mStep-by-step explanation:
As per given the formula for distance is:
d = 4√sIf s = 9 m/s, then the distance is:
d = 4√9 = 4*3 = 12 mSophia, Aiden, and Jaiden had a challenge to see who could bike the farthest in one day. Sophia biked 13 miles, Aiden biked 2 times as many miles as Jaiden and Jaiden biked 3 times as many miles as Sophia. How many miles did Aiden bike?
Answer:
78 is the answer
Step-by-step explanation:
ok so look below for steps to solve it!
step 1: it says Jaiden did 3* as many so multiply 3*13=39
step 2: then multiply 39*2=78
step 3: thus, the answer is 78

Some people have been complaining that the children's playground at a municipal part is too small and is in need of repair. Managers iof the pard decide to survey city residents to see if they believe the playground should be rebuild. They hand out questionnaires to parents who bring children to the park and asked: "Do you think the playground should be repaired and expanded even if that means raising the entrance fee to the park?" Which type of bias is most likely to have occurred in this situation?
a
Voluntary Bias
b
Wording Bias
c
Response Bias
d
Non-Response Bias
Answer:
c . Response Bias
Step-by-step explanation:
This is a convenience sampling and it could lead us to a response bias. Those parents who bring their children to play in the park would most likely to support rebuilding the park while the parents those who do not bring their children would not be sampled and thus would not be included in the sampling. This sample method involved is not representative of the entire population. So it is a responsive bias.
Define a variable, write an equation and solve: An investment increased 30% before taxes. $200 was withdrawn to pay taxes and the investor has $1500 remaining. What was the original investment?
Answer:
$1307.69
Step-by-step explanation:
Let the original investment be x.
Note that a 30% increase in a value is equal to multiplying a value by 130% and a withdrawal is to take out money. The final amount is $1500. Let’s write the equation with the information we have.
Equation:
130%x - 200 = 1500
(130/100)x = 1700
x = 1700(100/130) = $1307.69

Find the interquartile range (IQR) of the data in the box plot below.
Asap ASAP Please PLZ
Answer:
4 pencils
Step-by-step explanation:
Interquartile Range (IQR) = the range of the rectangular box = Third quartile (Q3) - First Quartile (Q)
Third Quartile (Q3) = 6
First Quartile (Q1) = 2
Interquartile Range (IQR) = 6 - 2
Interquartile Range (IQR) = 4 pencils

the value of an investment decreased by 10%. The original amount of the investment was $75 what is the current value of the investment?
Answer:
67.5
Step-by-step explanation:
the angles of a triangle are in the ratio 2:3:4 find the size of each angle
Answer:
40:60:80
Step-by-step explanation:
2x+3x+4x=180 (sum of ang. In tri. Is 180)
X=20
2x is 40
3x is 60
4x is 80
40 plus 60 plus 80 is 180.
Rewrite 2.568 - 1.2 to make the divisor a whole number. Select the answer
choice that shows the correct setup for long division and answer.
O A. 12)2.568 = 0.214
O B. 12) 2.568 = 2.14
O c. 12)
25.68 = 2.41
O D. 12) 25.68 = 2.14
SUBMIT
Answer:
D. 12) 25.68 = 2.14
Step-by-step explanation:
Given :
Divisor = 1.2
Dividend = 2.568
We can make the divisor a whole number by multiplying the divisor by 10,
i.e. Divisor = 1.2 x 10 = 12
Similarly , dividend = 2.568 x 10 = 25.68
Therefore,
2.14
12 | 25.68
(-) 24
16
(-) 12
48
(-) 48
0
Hence the answer is 2.14
The position of a particle moving along the x-axis is given by a twice-differentiable function x(t). If x(2) < 0, x'(2) < 0, and x''(2) <0, which of the following statements must be true about the particle at time t=2?
a. The particle is moving toward the origin at a decreasing speed.
b. The particle is moving toward the origin at an increasing speed.
c. The particle is moving away from the origin at a decreasing speed.
d. The particle is moving away from the origin at an increasing speed.
e. The particle is moving away from the origin at a constant speed.
Answer:
c. The particle is moving away from the origin at a decreasing speed.
Step-by-step explanation:
Since x(2) which represents the particles position is less than zero, that is, x(2) < 0, it shows that the particle is at the left of the origin at t = 2.
Also, x'(2) which represents the particle's speed at t = 2 is less than zero, that is, x(2) < 0, the particles speed is negative at t = 2.
Finally, since x"(2) which represents the particle's acceleration at t = 2 is less than zero, that is, x"(2) < 0, the particle's acceleration is negative at t = 2 and thus decreasing.
So, combining these three conditions together shows that the particle is moving away from the origin at a decreasing speed at time, t = 2.
Since [tex]x(2)[/tex], which represents the subatomic particle location, is below zero, that is, [tex]x(2) <0[/tex], it indicates that the particles are to the left of the origin at [tex]t = 2.[/tex]
Therefore, [tex]x'(2)[/tex], which represents the particle's speed at [tex]t = 2[/tex], is less than zero, implying that[tex]x(2) <0[/tex], the subatomic particle speed at [tex]t=2[/tex], is negative.Furthermore, because [tex]x"(2)[/tex], which represents that particle's acceleration at [tex]t = 2[/tex], is less than zero, [tex]x"(2)< 0[/tex], the particle's acceleration at [tex]t = 2[/tex] is negative and consequently declining.Considering these three requirements reveals that at the moment [tex]t = 2[/tex], the particle is moving away from the nucleus at a decreasing speed.Therefore, the answer is "Option C".

find the value of (x-6)/3 if x =21
Greetings.
The answer is 5.
Explanation:
[tex]\frac{x-6}{3}[/tex]
We want to know the value when x = 21. Therefore, substitute x = 21 in the expression.
[tex]\frac{21-6}{3}[/tex]
Evaluate 21-6 = 15
[tex]\frac{15}{3}[/tex]
Therefore, the answer is 5.

Step-by-step explanation:
g(x)=x^2-3 and h(x)=2x+5
find h(g(x))
We know that [tex]g(x) = x^2-3[/tex] and [tex]h(x) = 2x+5[/tex]. So, [tex]h(g(x))[/tex] is equal to [tex]h(x^2-3)[/tex], which is [tex]2(x^2-3)+5[/tex]. This can be simplified to [tex]2x^2-1[/tex].

The expression 2y + 2.6 is equal to ? for y = 1.4
Answer:
5.4 :))
Step-by-step explanation:
ok so first you take 2*1.4=2.8 (you replace the Y with the number)
so now you have 2.8+2.6 which is equal to 5.4
Answer:
5.4
Step-by-step explanation:
2*1.4 is 2.8. Now the expression is y2+2.6=. Now, that we figured out what 2y is, which is 2.8, we need to add on 2.6. 2.6 + 2.8 is equal to 5.4. Now, to write out the whole equation, it would look like this.
2y+2.6=?
y2+2.6=?
2.8+2.6=?
5.4
So in the end:
2y+(2.6)= 5.4
