Answer:
It moved for 152.7 seconds
Step-by-step explanation:
Time taken/ period, T :
[tex]{ \sf{T = \frac{distance}{speed} }}[/tex]
substitute the variables:
[tex]{ \sf{T = \frac{8482}{(200 \times 1000)} }} \\ \\ { \sf{T =0.042 \: hours }}[/tex]
In seconds:
[tex]{ \sf{T = (0.042 \times 3600) \: s}} \\ { \sf{T = 152.7 \: seconds}}[/tex]
Answer: 68.25 hrs.
Step-by-step explanation:
200 Km. to miles = 124.274 miles
8482 mi/124.274 mi =
68.25 hours
Select all the sets of numbers to which the following real numbers belongs:
✓ 64
Real Numbers
Irrational Numbers
Rational Numbers
Integers
Whole Numbers
Natural Numbers
Integers.
The integers are the whole numbers, their opposites, and 0 . From the given numbers, −7 and 8 are integers. Also, notice that 64 is the square of 8 so −√64=−8 . So the integers are −7,8,−√64 − 7 , 8 , − 64 .
Jaulas father throws Kayla a graduation party that costs $773. He pays the DJ $250, $75 for the cake, and $4 per party guest for food. How many guests were at the party?
Answer:
112 guests
Step-by-step explanation:
I. If her total cost is 773$
When Total = DJ + Cake + Guest
773 = 250 + 75 + 4(x)
773 = 325 + 4(x)
773 - 325 = 4(x)
448 = 4x
x = 448/4
x = 112
That makes guests are 112

Angle sum theorem. X=?
Answer:
x = 125
Step-by-step explanation:
All triangle interior angles add up to 180 so:
x + 25 + 30 = 180
x + 55 = 180
x = 180 - 55
x = 125

an equation of the line that passes
through the points (0, 3) and (5, -3)?
Answer:
y= -6/5x +3
Step-by-step explanation:
y = mx + b is the formula for every linear equation. m is the slope (comment if you don't know how to find the slope), and b is the y-intercept. You just have to find those terms and plug them in.

The length of each side of an equilateral triangle having an area of 9√3 cm² is
Answer:
6 cm
Step-by-step explanation:
Let each side of the equilateral triangle be a.
Given, area of an equilateral triangle = 9√3 cm2
Area of an equilateral triangle = (√3)/4 × (Side)²
=> (√3)/4 × a² = 9√3
[tex] {a}^{2} = \frac{9 \sqrt{3} }{ \frac{ \sqrt{3} }{4} } = \frac{9 \sqrt{3} }{ \sqrt{3} } \times 4 = 9 \times 4[/tex]
=> a² = 36
[tex] \sqrt{ {a}^{2} } = \sqrt{36} \\ a = (+ - )6[/tex]
∴ Side = 6 cm [taking positive square root because side is always positive]
if x is th didit at tense place and y is the digit at ones place,the two digit number formed by these digits is.......................

I think the two digit number formed would be
xy
seeing that x is on the tens place which is the second last place and y is on the ones place meaning it has to be the last value.

HELP ME PLS THIS NEEDS TO BE DONE TONIGHT AND TURNED IN TOMORROW The Hamiltons are paving their driveway. They are paving a rectangular area and an area in the shape of a parallelogram to make it easier to turn around and pull out of the driveway. A sketch of the plan for their driveway uses a scale of 1 in. for every 3 ft. What is the actual area of the entire driveway they want to pave?
Answer:
1350 ft²
Step-by-step explanation:
First off, I notice that the triangle at the bottom can fit the slant at the top to make a perfect rectangle.
This will leave us with a rectangle. We can add up 4 and 5 for the sum of 9, making one side 9 inches.
5 + 4 = 9 in
We multiply 9 by 3 to get the actual length of that side
9 x 3 = 27 ft.
We multiply 16 and two-thirds by 3 to get the actual length of the other side
[tex]16\frac{2}{3}[/tex] x 3 = 50 ft.
To find the area of this rectangle we multiply length and width
50 x 27 = 1350 ft²
Determine whether the following numbers are rational or irrational
Hi! I'm happy to help.
A rational number is a number that repeats, or stops.
First of all, 8/5, in fraction and decimal form (1.6), stops, So it is Rational.
Next, we have pi. This number, doesn't ever stop, or repeat. ( 3.1415926535 897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679...) So, pi, is Irrational.
Next, we have 0. This number stops, so it is Rational.
Next, we have[tex]\sqrt{1}[/tex], the square root of 1, is 1, because 1 squared is one. 1 stops, so it is Rational.
Next, we have 4.46466... This number doesn't stop, and it doesn't seem to repeat, so it is Irrational.
Next, we have -6. -6 stops, so it is Rational.
Finally, we have [tex]\sqrt{2}[/tex]. The square root of 2 is 1.41421356237...
This number doesn't stop, and doesn't repeat, so it is Irrational.
To sum it up: Number 1, 3, 4, and 6 are Rational, and Number 2, 5, and 7 are Irrational.

A bag of flour is 2.26 kg how much does it weigh round to the nearest pound
Amela put 15x- 4 gallons of gas in her car at the beginning of the week. She used 7x-3 gallons driving to work. Which of the following choices represents the
number of gallons left in her car?
A) 22x+7
B) 22x-7
C) 8x+1
D) 8x-1
Answer:
D) 8x - 1
Step-by-step explanation:
Let's say that x = 5. That would mean Amelia put 15(5) - 4 gallons of gas in her car, which equals 71 gallons. She used 7(5) - 3 gallons driving to work, which is 32 gallons used. 71 - 32 = 39 gallons left.
What else equals 39, you might ask?
8(5) - 1
40 - 1
39.

D is the answer

A triangle has side lengths of (x-6), (x+2) and (x-9). Find the perimeter of the triangle
Answer:
3x - 13
Step-by-step explanation:
The perimeter is just the distance around the triangle. We have all three sides, so we can just add them together to get the total distance.
(x-6) + (x+2) + (x-9)
Group:
x + x + x - 6 + 2 - 9
3x - 13

The work of a student to solve the equation 3(3y - 8) = 10 + 3y is shown below:
Step 1: 3(3y - 8) = 10 + 3y
Step 2: 6y - 5 = 10 + 3y
Step 3: 3y - 5 = 10
Step 4: 3y = 15
Step 5: y = 5
In which step did the student first make an error and what is the correct step?
Step 2: 9y - 24 = 10 + 3y
Step 2: 6y + 11 = 10 + 4y

If y varies inversely as x squaredand y = 6 when x = 30, what is y when x = 6?
Answer:
150 is write answer
Step-by-step explanation:
mark me a brainlist
Answer:
y = 150
Step-by-step explanation:
Given that y varies inversely as x² then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of variation
To find k use the condition y = 6 when x = 30 , then
6 = [tex]\frac{k}{30^2}[/tex] = [tex]\frac{k}{900}[/tex] ( multiply both sides by 900 )
5400 = k
y = [tex]\frac{5400}{x^2}[/tex] ← equation of variation
When x = 6 , then
y = [tex]\frac{5400}{6^2}[/tex] = [tex]\frac{5400}{36}[/tex] = 150
can we add 4x and 3y? why?
Answer:
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Answer:
no we cannot add them, though we can multiply or divide them. You cannot add them because they have different variables, we need the same variables to add or subtract those.

passes through (3,-1), perpendicular to the graph y= -1/3x-4 into slope intercept form
Answer:
y = 3x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{1}{3}[/tex] x - 4 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (3, - 1 ) into the partial equation
- 1 = 9 + c ⇒ c = - 1 - 9 = - 10
y = 3x - 10 ← equation of perpendicular line
0.21212121… as a fraction
Work Shown:
x = 0.212121...
100x = 21.212121....
Subtract the equations straight down. This means we subtract the left hand sides together, and the right hand sides are handled separately.
Left hand sides: 100x-x becomes 99xRight hand sides: 21.212121.... - 0.212121... becomes 21After those sets of subtractions, we are left with 99x = 21.
This solves to x = 21/99 when dividing both sides by 99 to isolate x.
Therefore, 21/99 = 0.212121...

PM = QM
[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]
Answer:
C.) x = 3
Step-by-step explanation:
The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.
