En cierta ocasión a Verónica le ofrecieron en su trabajo un aumento de 15 % en su salario mensual base, el cual era de $11 000.00, entonces me pidió que si le podía ayudar a determinar cuánto dinero le iban a aumentar. ¿Ya sabes cómo ayudar a Verónica?
Answer:
$12,650
No
Step-by-step explanation:
The computation of the increase in salary is shown below:
GIven that
The salary is $11,000
And, the increment percentage is 15%
So based on the above information
The salary after increment is
= $11,000 + $11,000 × 15%
= $11,000 + $1,650
= $12,650

The following data points represent the number of quesadillas each person at Tobys tacos ate, HELP
Answer: 1
Step-by-step explanation:
First order from least to greatest find the median wich would be 1 then slpit then split the numbers beyond the right side of 1 and split the split the numbers of the right aside of one. You should have 5 numbers on each side ( rember don’t include median) next find the median of both sides for the left it’s 1/4 and for the right it’s 5/4 subtract them to get 4/4 or the answer 1.
Answer:
Part 1: 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, 2.
Part 2: 1 quesadilla.
Step-by-step explanation:
Part 1: The data points given are 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, and 2.
The data are already sorted from least to greatest.
Part 2: To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.
There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.
Since we know the median is 1, we can find the first quartile by finding the median of the following numbers: 0, 0, 1/4, 1/2, 1/2 (any number less than 1). There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with a first quartile of 1/4.
Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "1": 1, 1, 5/4, 2, 2. Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with a third quartile of 5/4.
Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile. 5/4 - 1/4 = 4/4 = 1.
So, your interquartile range is 1 quesadilla.
Hope this helps!

Joey has a beach ball with a radius of 20 cm. What volume of air will it hold when fully inflated? [Round to nearest tenth.]
A) 83.8 cm3
B) 251.4 cm3
C) 1676.2 cm3
D) 33,493.3 cm3
Answer:
D) 33,493.3 cm3
Step-by-step explanation:
We know that
The volume of the sphere (beach ball) is equal to
[tex]V=\frac{4}{3} \pi r^{3}[/tex]
we have
[tex]r=20cm[/tex]
substitute
[tex]V=\frac{4}{3}\pi (20^{3} )=33,493.3 cm^{3}[/tex]
Answer:
D
Step-by-step explanation:
V=[tex]\frac{4}{3}[/tex] π [tex]r^{3}[/tex]
r=20 cm
V= [tex]\frac{4}{3}[/tex]π([tex]20^{3}[/tex])= 33,493.3 [tex]cm^{3}[/tex]

If 16*x=1/64, find the value of x
Answer:
I think it is x=1/1024 not sure but try it
Answer:
x = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Assuming you mean
[tex]16^{x}[/tex] = [tex]\frac{1}{64}[/tex]
note that 16 = 4² and 64 = 4³ , so
[tex](4^{2} )^{x}[/tex] = [tex]\frac{1}{4^{3} }[/tex]
[tex]4^{2x}[/tex] = [tex]4^{-3}[/tex]
Since the bases on both sides are equal, both 4, then equate exponents
2x = - 3 ( divide both sides by 2 )
x = - [tex]\frac{3}{2}[/tex] ( = - 1.5 )

Street C is perpendicular to Street A and passes through
(4, -6). Write this street's equation in point- slope form.
street a's equation was y= -2x +2
Given:
Street C is perpendicular to Street A and passes through (4, -6).
The equation of street A is:
[tex]y=-2x+2[/tex]
To find:
The equation of street C.
Solution:
The equation of street A is:
[tex]y=-2x+2[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m_2=-2[/tex]
Slope of this line is -2.
We know that, the product of slopes of two perpendicular lines is always -1.
[tex]m_1\times m_2=-1[/tex]
[tex]m_1\times (-2)=-1[/tex]
[tex]m_1=\dfrac{-1}{-2}[/tex]
[tex]m_1=\dfrac{1}{2}[/tex]
The slope of street C is [tex]m_1=\dfrac{1}{2}[/tex] and it passes through the point (4,-6). So, the equation of street C is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(-6)=\dfrac{1}{2}(x-4)[/tex]
[tex]y+6=\dfrac{1}{2}(x-4)[/tex]
Therefore, the point slope form of the street C's equation is [tex]y+6=\dfrac{1}{2}(x-4)[/tex].
In the third quarter of 2001, the median sale price for a single-family
home in Putnam County, New York, was $259,970. A year earlier, the
price was $242,555. What was the percent increase?
Answer:
The % increase is 7.179 but see the remark I made below. What I have given and what it could be is a rounding error. Less than 2 dollars error is not much when you are calculating something for someone just to show them how to do it.
Step-by-step explanation:
242,555 * x/100 = 259,970 Multiply by 100
242,555 * x = 259970 * 100
242,555 * x = 25997000 Divide by 242555
x = 24997000/242444
x = 107.179
That's the total increase.
What you want is 7.179%
If you take 7.179% of 242,555 and add it onto 242555 you should get 259,970
7.1797/100 * 242555 = 17413.02
17413.02 + 242555 = 259968.02
Why isn't it exact. I'm out just about 2 whole dollars. The reason is that the % isn't exact. It's only out to 3 decimal places which apparently is not enough. You can go over my numbers if you want more exactness us use something that is rounded to 7.180 if you like.

Find the total surface area of a cuboidal room whose
length ,breadth and height are 9m ,5m and 3m.
respectively.
Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
