Cubing of integers from 1 to 5 will have their cubes in the interval 1 to 200. There are such 5 positive numbers (1,2,3,4,5).
To calculate the variety of integers, locate and subtract the integers of the hobby after which subtract 1. As evidence of the concept, calculate the wide variety of integers that fall between five and 10 on more than a few lines. We realize there are four (6, 7, 8, 9).
All entire numbers are integers (and all herbal numbers are integers), however now not all integers are whole numbers or natural numbers. as an example, -five is an integer but not an entire variety or a natural quantity. An integer is an entire variety (not a fractional number) that can be fine, bad, or 0. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. Examples of numbers that are not integers are: -1.forty three, 1 3/four, three.14, . 09, and five,643.1.

If the measure of angle 4 is 130° what is the measure of angle 7
4 and 8 will equal the same since they are corresponding angles
So since 8 and 7 make a line they equal 180
180= 132+"7
Subtract both sides by 132

A painting measures b meters by 4 meters. a frame shop charges $10 per meter for a wooden frame. how much would it cost to buy a frame for the panting?
$ (20b + 80) is the cost to buy a frame for the panting given that measures b meters by 4 meters and charges $10 per meter for a wooden frame. This can be obtained by finding the perimeter of the painting and multiplying with the cost of wood per meter.
What is the cost of buying a frame for the painting?
Given that,
length of the painting (l) = b meters
width of the painting (b) = 4 meters
Perimeter of the painting = 2(l+b)
= 2(b+4)
= 2b + 8
Cost of the frame = (2b + 8)× $10 per meter
= $ (20b + 80)
Hence $ (20b + 80) is the cost to buy a frame for the panting given that measures b meters by 4 meters and charges $10 per meter for a wooden frame.

Pete is ahead of nick by 11 meters. Oliver is ahead of manny by 10 meters. Oliver is ahead of pete by 5 meters. How far is the runner in first place ahead of the runner
Answer:
The runner in first place is 16 meters ahead of the runner in last place
Step-by-step explanation:
There are 4 boys racing - Pete, Nick, Manny, and Oliver.
Pete is 11 meters ahead of Nick, Oliver is 10 meters ahead of Manny, and Oliver is ahead of Pete by 5 meters.
This means Oliver is ahead of the other three racers, putting him in first place, and Manny is between Nick and Pete.
So in order to find out the distance between the racer in first place (Oliver) and the racer in last place (Nick), add the distance between Oliver and Pete and the distance between Pete and Nick.
Add the distances: 5 + 11
Therefore, the runner in first place (Oliver) is 16 meters ahead of the runner in last place (Nick).
An adult female elephant weighs about 8000 pounds. a newborn baby elephant weighs about 200 pounds. write the ratio of the baby elephants weight to the adult female elephants weight as a fraction in simplest terms and as a decimal
Answer:
1/40 or 0.025
Step-by-step explanation:
the weight of baby el is 200
the weight of mama el is 8000
take 200/8000 and simplify.
if you divide the top by 200 then divide the bottom by 200
200 divided by 200 is 1
8000 divided by 200 is 40
so the simplest fraction is 1/40
if you type this in to a calculator, you will find that it equals 0.025
The measure of major arc TBU is.

U
T

B
?
Answer:
arc TBU = 268°
Step-by-step explanation:
the measure of the tangent- chord angle TUV is half the measure of its intercepted arc UT , then
UT = 2 × 46° = 92°
the sum of the arcs in a circle = 360° , that is
TBU + UT = 360°
TBU + 92° = 360° ( subtract 92° from both sides )
TBU = 268°
How many distinct pairs of positive consecutive integers have a product less than 10,000?
Please explain it step-by-step
Step-by-step explanation:
Let the consecutive positive integer be x , x+1
now, we know that there product is less then 10000
so, x(x+1) = 10000
x² + x - 10000 = 0
On solving the quadractic equation,
we get the roots = (-100.50124999219 ), (99.501249992188)
since we are asked for less then 10000 we can approximate the answer to x = 99.5
Answer:
99.5
Step-by-step explanation:
Let the consecutive positive integer be n , n+1
now, we know that there product is less then 10000
so, n(n+1) = 10000
So, the question asked " Less than 10,000 " so, we get the roots = (-100.50124999219 ), (99.501249992188)
n² + n - 10000 = 0
Let's solve this equation together!

The sesame street tube bought by the blue bird costs $177.92 which contained one gallon of toothpaste.
Given,
cost of regular toothpaste = $1.39 for 2.7 ounce tube
But the bird took a tube of toothpaste that contained one gallon of toothpaste.
One gallon = 128 ounces
∴the total price at which the toothpaste is brought = price of normal toothpaste × one gallon(128 ounces)
= 1.39 × 128
=$177.92
Here we can observe that a gallon contains 128 ounces. so we need to multiply to the initial cost of the toothpaste to get the final amount of the toothpaste bought by the bird.
Hence the price at which the bird bought the toothpaste is $177.92

The area of the square LMNP is 50 square units
How to determine the area of the square?The circumference of the circle is given as:
C = 10π
Circumference is calculated as:
C = 2πr
So, we have:
2πr = 10π
Divide by 2π
r = 5
This represents the length OM
The length PM is calculated as:
PM = 2 * OM
This gives
PM = 2 * 5
PM = 10
The length (PN) of the square is then calculated as:
PM = PN√2
This gives
10 = PN√2
Square both sides
100 = PN^2 * 2
Divide by 2
50 = PN^2
Rewrite as:
PN^2 = 50
