Answer:
-10
Step-by-step explanation:
take out the parantheses
2x + 6 = x - 4
Put the variable on the left side of the ecuation with the opposite sign
2x + 6 -x = -4
Put the six on the right side of the equation and change the sign
2x - x = - 4 - 6
simplify
x = - 4 - 6
x = -10
two sides of a right triangle have lengths of 60 feet and 75 feet.

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
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]

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

Bill and juan are competing to see who can run more miles in a week billy ran 14 miles on day 1 and then ran 6 miles per day for the remaining time. Juan ran 10 miles on day 1 and then ran 7.5 miles per day for the remaining time after how many days did billy miles ran become less than the miles juan ran
Answer:
x < 2.67 days
Step-by-step explanation:
Let
Number of days = x
Billy = 14 + 6x
Juan = 10 + 7.5x
Bully < Juan
14 + 6x < 10 + 7.5x
14 - 10 < 7.5x - 6x
4 < 1.5x
x < 4/1.5
x < 2.67 days

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].
