Olivia and Isabella each earn d dollars for each dog she walks. One day, Olivia walks 6 dogs and gets $8 in tips. That same day, Isabella walks 9 dogs and gets $12 in tips.
a. Olivia writes 6d + 8 + 9d + 12 to represent the amount
they earn together. Isabella writes 5(3d + 4). Are their
expressions equivalent? Show your work.
Answer:
Yes they are equivalent, both equations equals [tex]15d+20[/tex]
Step-by-step explanation:
We first simplify Olivia's equation
[tex]6d + 8 + 9d + 12[/tex]
1. we combine like terms in the equation: [tex]6d + 8 + 9d + 12[/tex]
[tex]6d+9d[/tex]
[tex]8+12[/tex]
[tex]15d+20[/tex]
Now we simplify Isabella's
[tex]5(3d + 4)[/tex]
1. we do distributive property
[tex]5*3d[/tex]
[tex]5*4[/tex]
[tex]15d+20[/tex]

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1661 square feet? Use 3.14 for .
Answer: 23 feet
Step-by-step explanation:
The question simply means that we should calculate the radius of the circle. In this case, the area has been given to be 1661ft².
Area of a circle = πr²
πr² = 1661ft²
3.14(r²) = 1661
r² = 1661 / 3.14
r² = 528.98
r = ✓528.98
r = 23
The solution is 23 feet.

Compare the shapes of the box plots.
A. The distributions for both towns are positively skewed.
OB. The distribution for town A is symmetric, but the distribution for
town B is positively skewed.
C. The distribution for town A is symmetric, but the distribution for
town B is negatively skewed.
D. The distributions for both towns are symmetric.
Answer:
The answer is B.
Step-by-step explanation:
As you can see, box plot A is symmetrical so that applies to answers A and B. However, box B is very skewed to the right which makes it positively skewed so answer B is the only one that matches the correct description of the two box and whisker plots.
We can conclude that the distribution for town A is symmetric, but the distribution for town B is positively skewed.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
The distribution for town A is symmetric, but the distribution for town B is positively skewed.
We can determine the skewness of the distributions by comparing the position of the median with respect to the quartiles.
In town A,
The median (30) is located at the center of the box, and the first and third quartiles (20 and 40, respectively are equidistant from the median.
This indicates a symmetric distribution.
In town B,
The first and third quartiles (20 and 30, respectively) are closer to the median (25) on the left-hand side of the box than on the right-hand side. This indicates a positively skewed distribution.
Therefore,
We can conclude that the distribution for town A is symmetric, but the distribution for town B is positively skewed.

a) 1.415
(b) 1.397
(c) 1.645
(d) 2.896
(e) 0.90
The critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
The t-distribution with 8 degrees of freedom has probability 0.10 to the right of t.
That is, df = 8,
α = 0.10 by using these values, the critical value of t is obtained.
From the t-distribution table:
The critical value is 1.3968.
The critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.
Therefore, the critical value of t has probability 0.10 to the right with 8 degrees of freedom is 1.3968.

What is the distance D across the chemical spill? ASAP help
Answer:
10
Step-by-step explanation:
There's probably a lot of ways you could solve this. I think what I would do is find the top angle of the big triangle first because it will be the same as the angle accross from it in the little triangle. We'll call this angle X1 for the big triangle and X2 for the little triangle.
X1 = X2
TAN(X1) = opposite/adjacent
TAN(X1) = 50/40
X1 = CoTAN(50/40)
X1 = 51.34 = X2
TAN(X2) = d/8
TAN(51.34) = d/8
d = TAN(51.34) * 8
d = 10
If you're unfamiliar with trig functions you could also use a proportion.
[tex]\frac{50}{40} =\frac{d}{8}[/tex]
cross multiply to get
400 = d*40
divide by 40
d = 10
Now that I look at it, that's probably the way they want you to do it, but as you see, it works either way!

El interior de un tanque que contiene agua, tiene una presión manométrica de 300 kPa. ¿Qué profundidad tiene el tanque de agua?
Respuesta:
30,6 metros
Explicación paso a paso:
Dado :
Presión = 300 Kpa
Usando la fórmula que relaciona la presión y la profundidad:
Presión = profundidad * aceleración debida a la gravedad * densidad del agua
Densidad del agua = 1000 kg / m³
Presión = 300Kpa = 300 * 10 ^ 3 Pa
300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000
300000 = profundidad * 9800
Profundidad = 300000/9800
Profundidad = 30,612
Profundidad = 30,6 m
