In a math game, Bradley was supposed to find the square root of a number. Instead the squared the number and said "81."
What number should Bradley have given?
Answer:
The square root of 81 is 9, the square root of 9 is 3, your answer is 3
Step-by-step explanation:
3x3=9, 9x9=81
The required squared number that Bradley should give is 9.
Given that,
In a math game, Bradley was supposed to find the square root of a number. Instead, they squared the number and said "81."
To determine the number that should Bradley have given.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number be x,
Bradley said it is 81
Now accoding to the question,
x = √81
x = √9*9
x = 9
Thus, the required squared number that Bradley should give is 9.

Write an equation of a line in slope-intercept form that passes through (-3,5) and is parallel to y = -6x +1.
Then find its x- and y-intercepts.
Answer:
a) The equation of the Parallel line to the given straight line is
6 x + y + 13 =0
b) Slope - intercept form
y = - 6 x - 13
c) The intercept - form
[tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]
x - intercept = [tex]\frac{-13}{6}[/tex]
y - intercept = - 13
Step-by-step explanation:
Step(i):-
Given the equation of the straight line
y = -6x +1
6 x + y - 1 = 0
The equation of the Parallel line to the given straight line is
6x + y + k=0 and it passes through the point (-3, 5 )
⇒ 6 (-3 ) + 5 + k =0
⇒ - 18 + 5 + k=0
⇒ -13 + k = 0
⇒ k = 13
The equation of the Parallel line to the given straight line is
6 x + y + 13 =0
Step(ii):-
Slope - intercept form
y = m x + C
y = - 6 x - 13
Step(iii):-
Intercept - form
6 x + y + 13 =0
6 x + y = - 13
[tex]\frac{6x + y}{-13} = \frac{-13}{-13}[/tex]
[tex]\frac{6x}{-13} + \frac{y}{-13} = 1[/tex]
[tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]
The intercept - form
[tex]\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1[/tex]
x - intercept = [tex]\frac{-13}{6}[/tex]
y - intercept = - 13

4 x 2 = 8
She makes a total of 8 dollars
She also gains $3.00 per half hour of work
This means we would do 3 x 8

Darla can do a job in eight hours while Lonnie can do the same job in six hours. Both Darla and Lonnie work three hours on the job. How much of the job is left to be finished
Answer:
Look below ⏬
Step-by-step explanation:
Darla 8h
Lonnie 6h
They both worked 3 hours now
subtract
8-3=5
6-3=3
Darla have 5 hours to finish
and...
Lonnie has 3 hours to finish
all together is 8 hours in all
1/8 part of the job is left to be finished if both Darla and Lonnie works for three hours on the job.
What is Fractions?Fractions are the part or portion of a whole.
For example, fraction 1/2 means 1 part of the 2.
Time taken by Darla to do the job = 8 hours
Time taken by Lonnie to do the job = 6 hours
Let J represent the job.
In 8 hours, Darla completes J.
In 3 hours, Darla completes 3/8 J
In 6 hours Lonnie completes J.
In 3 hours, Lonnie completes 3/6 J.
The work completed = 3/8 J + 3/6 J
= J [ 3/8 + 3/6]
= J [3/8 + 1/2]
= 7/8 J
7/8 parts of the job is completed.
Job left to finished = J - 7/8 J = 1/8 J
Hence 1/8 part of the job is left to be finished.

Step-by-step explanation:
Let us imagine that 0 on the numberline. -9.2 is to the left, and 4.5 is to the right of zero.
Since distance as positive, we can simply add the absolute values of -9.2 and 4.5 to obtain the distance:

distance covered by minute hand in 1 hour is 94. 20 cm find the circumference of the circle whose radius is 12 CM
Answer:
[tex]\large\boxed{75.4cm(1 d.p)}[/tex]
Step-by-step explanation:
Important Information:
Circumference of a cirlce= [tex]\pi*diameter[/tex]
Diameter= [tex]2*radius[/tex]
Method:
The first step in working out the circumference of this cirlce is to work out the diameter. You can work this out by multiplying the radius of 12 by 2, this gives you 24cm. This is because the radius is half of the diameter.
The next step is to work out the circumference. You can do this by multiplying pi by the diameter of 24, this gives you [tex]27\pi[/tex] or 75.4cm (1 d.p).
Step by Step:
1) Multiply 12 by 2.
[tex]12*2=24cm[/tex]
2) Multiply pi by 24.
[tex]\pi*24=75.4cm(1 d.p)[/tex]

Solve the equation using the multiplication property of equality and the reciprocal of 1 4 . 1 4 ( r − 5 2 ) = 1 8 What is r? r = one-third r = 3 r = two-thirds r = one-half
Answer:
3
Step-by-step explanation:
1/4(r - 5/2) = 1/8
1/4r - 5/8 = 1/8
1/4r = 1/8 + 5/8
1/4r = 6/8
Divide both sides by 1/4
1/4r ÷ 1/4 = 6/8 ÷ 1/4
1/4r * 4/1 = 6/8 * 4/1

Henry is flying a kite. The kite makes an angle of 43 with the ground. If henry is standing 100 feet from a point on the ground directly below the kite, find the length of the kite string
Answer:
x = 136.73 feet
Step-by-step explanation:
Given that,
Henry is flying a kite. The kite makes an angle of 43 with the ground. If henry is standing 100 feet from a point on the ground directly below the kite.
We need to find the length of the kite string. It can be calculated by using trigonometry.
The length of the string will be hypotenuse, 100 feet is the base.
The relation between the hypotenuse, base and angle with the ground is given by :
[tex]\cos\theta=\dfrac{\text{base}}{\text{Hypotenuse}}\\\\\cos(43)=\dfrac{100}{x}\\\\x=\dfrac{100}{\cos(43)}\\\\x=136.73\ \text{feet}[/tex]
So, the length of the kite string is 136.73 feet.
