First and foremost, we need to note that 1000 millimeters = 1 meter. Therefore, for us to convert 3500 millimeter to meters, we have to divide it by 1000. This will be:
= 3500/1000
= 3.5 meters
Kyle earned 4 times as much as Ken last summer. If they earned a total of $750, how much did they each earn?
Show all work
(Please help will give brainliest)
Answer:
600, 150
Step-by-step explanation:
Kyle is x
ken is y
x = 4y
x+y = 750
replace x with 4y
4y + y = 750
5y = 750
y = 150
so ken earned 150
x + 150 = 750
x = 600
so Kyle earned 600

(see picture below)
thank you!
Answer:
x = 12
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
x² = 6(6 + 18) = 6 × 24 = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12
Another Eurasian lynx traveled for 301 days. It traveled a distance of 77.8 miles. How many miles per week did it travel
Answer: 1.8 miles per week
Step-by-step explanation:
The European lynx travelled for 301 days and in that time covered a distance of 77.8 miles.
Convert the number of days to weeks:
= 301 / 7
= 43 weeks
If it travelled 77.8 miles in 43 weeks, its speed was:
= 77.8 / 43
= 1.8 miles per week

a jar contains 6 red jelly beans, 6 green beans, and 6 blue jelly beans if we choose a jelly bean, then another jelly bean without putting the first one back in the jar, what is the probability that the first jelly bean will be green and the second will be green as well
======================================================
Explanation:
We have 6 green out of 6+6+6 = 18 total
The probability of getting green is 6/18 = 1/3.
After selecting that green jelly bean and not putting it back, we have 6-1 = 5 green out of 18-1 = 17 total.
The probability of selecting another green is 5/17.
Multiply the two fractions 1/3 and 5/17
(1/3)*(5/17) = (1*5)/(3*17) = 5/51
The probability of selecting two greens in a row is 5/51 where we do not put the first selection back. We also do not replace the green jelly bean with some other identical copy.
Note: 5/51 = 0.098039 approximately

A container in the shape of a rectangular prism has a base with an area of 19 1/2 square inches. If the container is filled with water to a height of 4 1/2 inches, how much water is in the container?
Answer: Water in the container = 87.75 cu.inches.
Step-by-step explanation:
Formula: Volume of rectangular prism = Base area x height
Base area = [tex]19\dfrac12[/tex] sq. inches Height = [tex]4\dfrac12[/tex] inches
So,
Volume of container = [tex]19\dfrac12\times4\dfrac12\text{ cu.inches}[/tex]
[tex]=\dfrac{39}{2}\times\dfrac{9}{2}\text{ cu.inches}[/tex]
[tex]=\dfrac{351}{4}\text{ cu.inches}[/tex]
[tex]=87.75\text{ cu. inches}[/tex]
Hence, Water in the container = 87.75 cu.inches.

If EF is the perpendicular bisector of CD, find x.
Answer:
Step-by-step explanation:
A Perpendicular Bisector cuts a segment into two equal parts. We already know that 4x+19 and 6x-7 are both equal.
So then, you would start with 6x-7 = 4x+19.
6x-7 = 4x+19
Subtract -4x from both sides
2x-7 = 19
Add 7 to both sides
2x = 26
Divide both sides by two
x= 13
You only need x, so you're done.
(I'm like 90 percent sure this is wrong man don take my word for it bro).
The value of x will be 13.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
EF is the perpendicular bisector of CD.
Measure of length CE = 4x + 19
Measure of length ED = 6x - 7
Now,
Since, EF is the perpendicular bisector of CD.
So, We can formulate;
⇒ Δ EFC ≅ Δ EFD
Hence, Measure of length CE = Measure of length DE
Substitute all the values, we get;
⇒ 4x + 19 = 6x - 7
Solve for x as;
⇒ 4x + 19 = 6x - 7
Subtract 6x both side, we get;
⇒ 4x - 6x + 19 = 6x - 7 - 6x
⇒ - 2x + 19 = - 7
Subtract 19 both side,
⇒ - 2x + 19 - 19 = - 7 - 19
⇒ - 2x = - 26
Divide by - 2, we get;
⇒ x = 13
Thus, The value of x will be 13.

the height of a hat is shaped like a cone is 10 inches. the volume of thw hat is 30(pi) cubic inches. what is the diameter of the hat?
Answer:
3.38pi
Step-by-step explanation:
Using simple math and the equation for finding the volume of a sphere, we can see that by taking the height of 10, and the volume of 30, that with that information we can deduce that the radius of the cone would be 1.69pi. With this information, we know the radius is half of the diameter. Therefore, we multiply 1.69 by 2, to get our end result, 3.36pi
In parallelogram , ABCD ∠A has a measure of 62° . Find the measures of ∠B and ∠C.
Answer:
118
Step-by-step explanation:
If angle A is 62 degrees, then angle D is 62 degrees. 62+62=124, and 360-124 is 236 (360 is the total interior angles of any quadrilateral). Then, 236/2=118. You divide it by two because you are looking for angles B and C separately.

Celesta used to spend 90 minutes a day on the phone. Now she spends 60 minutes a day. What is the PERCENT DECREASE?
Answer:
-210
Step-by-step explanation:
The percent decrease in the time taken by Celesta is 33.33%.
What is Percentage?Percentage of a number is the parts per 100. Or percentage of a number can be calculated by dividing the number with the whole with respect to which we are finding the percentage of the number and then multiply with 100.
Percentage is a dimensionless number because percentage is not measured by any units.
Percentage decrease can be calculated by the formula,
Percentage Decrease = [(Original value - New value) / Original value] × 100
Time that Celesta used to spend on the phone a day = 90 minutes
Original value = 90
Now, celesta spends 60 minutes a day
New value = 60
Percentage decrease = [(90 - 60) / 90] × 100
= [30 / 90] × 100
= [1 / 3] × 100
= 33.33 %
Hence the percent decrease in the time taken by Celesta in a day is 33.33%.
