carla wrote this number:815,247 travis wrote this number: 638.571 the digit 8 in carlas number represents how many times what the digit 8 represents in travis number?(55 points)
The 8 in Carla's number is 100 times the 8 in Travis' number.
How many times what the digit 8 represents in Travis number?Here you need to understand the concept of place value. For any number, each digit is always a order of magnitude of 10 larger than the digit in the left.
For example, in 88
The first 8 is 10 times larger than the second one.
There comes the concept of place value, the first digit at the left of the decimal point represents the units, the second represents the tens, the third one the hundresd, and so on.
So, in the two given numbers:
815,247 Here the 8 represents the hundreds of thousands.
638,571 Here the 8 is in the thousands place value.
Then the relation between the first 8 and the second one is:
100,000/1,000 = 100
The 8 in Carla's number is 100 times the 8 in Travis' number.

The relation 7 is a function and the relation 9 is not function.
How to determine whether each relation is a function?Relation 7
The relation is given as
{(-3, -3), (-2, -2), (-1, -1), (0, 0)}
For a relation to be a function, no x value must point to multiple y value
Using the above statement as a guide, the relation is a function.
This is so because each domain value {-3, -2, -1, 0} point to different range value {-3, -2, -1, 0}

The larger room is twice as wide as the smaller room which is 29 3/4’. How wide is the
larger room?
Based on the fact that the larger room is twice as wide as the smaller room, the width of the larger room is 59¹/₂ inches.
How wide is the larger room?The larger room is twice the width of the smaller room.
If the smaller room is 29³/₄ inches therefore, the width of the larger room will be:
= Width of smaller room x 2

Over the last baseball season, Billy averaged 28 hits per 100 turns to bat, while Carl averaged one hit for every 2.5 turns. At these rates, which player would have more hits in 500 turns to bat, and how many more?
Using proportions, it is found that Carl would have 60 more hits in 500 turns.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Billy's proportion is of 28/100, hence his amount of hits in 500 turns is:
500 x 28/100 = 140 hits.
Carl's proportion is of 1/2.5, hence his amount of hits in 500 turns is:
500 x 1/2.5 = 200 hits.
The difference is:
200 - 140 = 60 hits.
Carl would have 60 more hits in 500 turns.

Write the improper fraction 30/7 as a mixed number
Answer:
Step-by-step explanation:
30/7 = 4 2/7
Because 7 only goes into 30, four times (7 x 4 = 28) anything else would be too big.
7 goes into 30 four times, and you get left with a remainder of 2
So you write 4 wholes, then 2/7 because 2 is the remainder it goes on top, and 7 stays in the denominator (bottom)
solve for u.
(u-7) (u - 13)=0
Answer:
u = 7 OR u = 13
Step-by-step explanation:
Using the zero property of multiplication, you know you have to make either u-7 or u-13 equal to zero. You get the two solutions from these two cases, where you make either of the equations equal to 0:
u - 7 = 0
Add 7 to both sides
u = 7
u - 13 = 0
Add 13 to both sides
u = 13
FINAL ANSWER: u = 7 OR u = 13

What is the linear speed in miles per hour of the tip of a lawnmower blade spinning at 2800 revolutions per minute in a lawnmower that cuts a path that is 26 inches wide?
What is the angular speed in degrees per hour?
The linear speed in miles per hour of the tip of a lawnmower blade spinning is 0.0601509076 miles per hour and angular velocity is 293.276 rad/hr.
What is linear speed?The measurement of a moving object's actual distance traveled is called linear speed. Linear speed is the rate of motion of an item along a straight line. It is the distance traveled along a linear path in the allotted amount of time.
2800 rotations per minute on a lawnmower blade.
Specifically, the frequency of the blade is 2800 revolutions per hour,
f = 2800 / 60, or 46.66.
The angular velocity is
ω = 2πf
where f = frequency
ω = 2 × 3.14 × 46.7
ω = 293.276 rad/hr
The diameter of the circle centered at the blade's middle determines the path's breadth.
26 inches in diameter
radius = 26 / 2 = 13
13 inch = 0.0002051 miles
Velocity is given by -
V = ωR
V = 293.276 × 0.0002051

Point B is between points A and C. AC-10x+6, AB=5x, and BC-4x+12, Find AB.
The value of AB that is 5x is equal to 30.
It is given that the points A, B and C are collinear. Collinear points may be defined as three or more points which lie on a straight line.
Here B lies between A and C and the three points A, B and C are collinear. Thus, according to property of collinear points:
AB+BC=AC
Now, according to question AB=5x, BC= 4x+12 and AC= 10x+6.
So, 5x+4x+12=10x+6
Taking the like terms on one side;
12-6 = 10x+9x
=> x=6
Now, AB=5x, thus AB= 5×5=30
Therefore, the value of AB is 30.

Step-by-step explanation:
so it starts with

as the price is inversely related to D.
(a)
so, in general
D = 182 × 3/p = 546/p
(b)
D = 546/3.25 = 168 bags
if the price increases to $3.25, then they will sell only 168 bags.
I am sure, the function will not stay linear for every value of p. for example, if they increase the price to $546 per bag, they would still sell 1 bag. but I am certain, they would fall to 0 sold bags much, much earlier than that ...

The area of the region inside the rectangle that surrounds the square is; 162 square meters
How to find the area of regular shapes?
We are given that;
Side length of square = 6 m
Width of rectangle = 11 m
Length of rectangle = 18m
Thus;
Area of rectangle = width * length = 11 * 18 = 198 square meters
Area of square = side * side = 6 * 6 = 36 square meters

Step-by-step explanation:
hmmm, it is all there, you only need to write it up.
so, please, let me know what you don't understand about such equations and variables.
(a)
2x + 5y = 45
8x + 3y = 44
(b)
to solve this we try to use either one equation to express one variable by the other. and solve for that remaining variable (and then drive the second one from that), or to combine both equations directly to eliminate one variable and solve.
I think the second option is best here.
so, we multiply the 1st equation by -4, and then we add both equations :
-8x - 20y = -180
8x + 3y = 44
-------------------------
0 - 17y = -136
-17y = -136
17y = 136
y = 8
2x + 5y = 45
2x + 5×8 = 45
2x + 40 = 45
2x = 5
x = 2.5

How much does Robert have left after deducting tax?Tax can be defined as the compulsory levy paid by citizens of a particular country on their income, goods and be services.
Amount Robert started with = $40Amount Robert spent before tax = $30.45Tax rate = 7.25%Amount of tax = Tax rate × Amount Robert spent before tax

The length of a rectangle is 4yd longer than its width.
If the perimeter of the rectangle is 68yd, find its length and width.
Answer:
Length= 19 yd
Width= 15 yd
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of all its sides.
Mathematically, it can be represented as below:
[tex]\boxed{\text{Perimeter of rectangle}=2\text{(length}+\text{width)}}[/tex]
Define variables used:
Let the length and width of the rectangle be L and W yards respectively.
Form an equation:
Given that the length of the rectangle is 4 yards longer that the width,
L= W +4 -----(1)
Next, form another equation using information on the perimeter.
68= 2(L +W) -----(2)
Substitute equation (1) into (2):
68= 2(W +4 +W)
68= 2(2W +4)
Divide both sides by 2:
34= 2W +4
Subtract both sides by 4:
2W= 34 -4
2W= 30
Divide both sides by 2:
W= 30 ÷2
W= 15
Substitute W= 15 into (1):
L= 15 +4
L= 19
Therefore, the length and width of the rectangle is 19 and 15 yards respectively.

The required distance is 16.40 km.
This problem can be solved if we know the concept of speed, time and distance.
We know the speed=[tex]\frac{distance}{time}[/tex]
To solve the problem let us assume that the total distance between the workplace and home is x km.
Given that his speed while going from home to work is 45 mph and while returning is 35 mph.
Time for the complete journey is [tex]\frac{5}{6}hr[/tex].
Now according to question;
[tex]\frac{x}{45}+\frac{x}{35}=\frac{5}{6}[/tex]

We need to evaluate the left hand side to find the value of a in the equation in simplest form.
We know that:
x^ (a) / x^ (b) = x^ ( a - b)
Using this, we get that:
x^ (3 - 1/6) = x^ (a)
