Answer:
$465
Step-by-step explanation:
The problem statement tells you h represents the number of hours, and the number of hours is 7.
It also tells you f represents the number of fixtures, and the number of fixtures is 9.
And, the problem statement tells you the charge is 15h+40f, which is 15 times the number of hours plus 40 times the number of fixtures. Then the charges are ...
15·7 +40·9 = 105 +360 = 465
Ben Frank charges $465 for the work.
Answer:
if it wants an equation, 105h+360f but if its all together then its 465$
Step-by-step explanation:
15x7=105h
40x9=360f

-2x+7y=14 identify the x-intercept and y-intercept
Answer:
x=7/2y − 7
Step-by-step explanation:
Let's solve for x.
−2x+7y=14
Step 1: Add -7y to both sides.
−2x+7y+−7y=14+−7y
−2x=−7y+14
Step 2: Divide both sides by -2.
−2x/−2 = −7y+14/−2
x=7/2y − 7

Answer:
The moon equals 7
and the stars equal 4
Step-by-step explanation:
Equation 1:
(substitute the symbols for the numbers)
7 + 1 = 4 + 4 (<< This is correct, both sides equal 8)
Equation 2:
(again, substitute the symbols)
7 = 3 + 4
That is correct.

find the missing side of the triangle
Answer:
x= 8 km
Step-by-step explanation:
measurement used:
When getting measurement the missing side occupies 1 more than a half of 15km
Answer:
x = 8km
Step-by-step explanation:
Use Pythagorean Theorem:
c2 = a2 + b2
In the diagram given, the hypotenuse (c) is 17 so substitute these values into the equation
17^2 = x^2 + 15^2
Take 15 to the power 2, to the other side.
17^2 - 15^2 = x^2
Solve to get
64 = x2
Square root both sides so
x = 8

How many solutions exist for the given equation?
1/2(x + 12) = 4x-1
zero
one
two
infinitely many
Answer:
one
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )
x + 12 = 8x - 2 ( subtract x from both sides )
12 = 7x - 2 ( add 2 to both sides )
14 = 7x ( divide both sides by 7 )
2 = x
There is one solution to the equation, that is x = 2
A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5
-5+x-7 what does x equal
Answer:
Since there is no equal sign x can not have an actual value, the equation simplified would be

Five less than the product of 6 and a number equals 7
Answer:12
Step-by-step explanation:you start at the beginning like 6 times 1 is 6 but 6 times two is 12 minus 5 equals 7
The statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the statement -
"Five less than the product of 6 and a number equals 7"
We can model this statement as an expression as follows. Let the number be {x}. Then, we can write that -
6x - 5 = 7
Therefore, the statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).

Una persona hace un trabajo en 6 horas, una segunda hace el trabajo en 8 horas y una tercera hace el trabajo en 10 horas. Si las tres personas trabajan al mismo tiempo ¿Cuánto tiempo durarán haciendo el trabajo?
a) 1 16/47 horas.
b) 2 26/47 horas.
c) 3 1/47 horas.
d) 4 36/47 horas.
Answer:
b) [tex]2\dfrac{26}{47}\ \text{horas}[/tex]
Step-by-step explanation:
Tiempo necesario para completar el trabajo en primera persona = 6 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{6}[/tex]
Tiempo necesario para completar el trabajo por segunda persona = 8 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{8}[/tex]
Tiempo necesario para completar el trabajo por tercera persona = 10 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{10}[/tex]
El tiempo necesario para completar el trabajo juntos viene dado por
[tex]\dfrac{1}{\dfrac{1}{6}+\dfrac{1}{8}+\dfrac{1}{10}}=\dfrac{1}{\dfrac{47}{120}}\\ =\dfrac{120}{47}=2\dfrac{26}{47}\ \text{horas}[/tex]
El tiempo necesario para completar el trabajo juntos es [tex]2\dfrac{26}{47}\ \text{horas}[/tex].

A new pain reliever is advertised as being 97%
effective. To 3 decimal places, what is the
probability that the pain reliever will be effective
in 12 independent trials?
A. 0.116
B. 0.694
C. 0.970
D. 0.847
Answer:
B. 0.694
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the pain reliever is advertised as being 97% effective, for it to be effective in 12 independent trials
= (97%) ^ 12
= 0.693842361
The is approximately 0.694 to 3 decimal places
Answer:
B. 0.694

The end of a minute hand on a clock is 5.5 inches from the center. How far will the minute hand travel over three days
Answer:
Step-by-step explanation:
Given :
Radius, r = Length of hour hand = 5.5 inches
A complete cycle is traveled in 24 hours ;
C = 2πr
C = 2 * π * 5.5 = 34.557519 inches
In 3 days : It will travel 3 full cycles
3 * C = 3 * 34.557519 inches
= 103.672557 inches
