Assume that lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?
9514 1404 393
Answer:
x = 20, or 125
Step-by-step explanation:
We cannot tell the angle x is intended to refer to. So, here are two answers. Choose the one you think applies.
__
The triangle that includes both marked angles is a right triangle. (The tangent meets the circle at right angles to the radius.) So, the angle x° at the external point is the complement of the marked central angle.
x° = 90° -70°
x = 20
__
If x° is referring to the exterior angle associated with the isosceles triangle within the circle, then its measure is the supplement of the interior base angle of that triangle. It is ...
x° = 180° -(180° -70°)/2 = 90° +70°/2
x = 125
If Earth's total mass is 6 x 10^24 kg, what proportion of this is lost every year?
Step-by-step explanation:
This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.
Factor X^2-13x+22 help pls
Answer:
(x-2)(x-11)
Step-by-step explanation:
Answer:
(x - 2)(x - 11)
Step-by-step explanation:
We have a polynomial and are asked to factor it.
Polynomial : x^2 - 13x + 22
Usually a trick I follow when factoring is that for c (in this case 22). You need to find two numbers that will multiply to it. And for b (in this case -13) you will need to find two numbers that will add to it, the same numbers you multipled for c.
So
x * y = 22
x + y = -13
These two numbers are -11 and -2.

A polygon has perimeter 12 units. It is dilated with a scale factor of 3/4. What is the
perimeter of its image?
A. 9 units
B. 12 units
C. 16 units
With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.
Given that, the perimeter of a polygon = 12 units and the scale factor = 3/4.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
So, 3/4 = Dimensions of the new shape/12
= 3/4 × 12
= 3 × 3
= 9 units
With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.

The second option is correct.
Step-by-step explanation:
First you need to find a common denominator in which is 6
You can find it like this:
1 x 3 = 3
2 x 3 = 6
3/6 is the amount of cake that was left
Now do the same thing for the amount of cake that Elisa ate.
1 x 2 = 3
3 x 2 = 6
So in conclusion the second option represents the amount of cake Elisa eats the best.
I hope this is as helpful as possible.
Answer:
Model:
2/3 (original amount of cake) - 1/3 (what was left) = 1/3 (what Elisa ate)
Math:
2/3 - 1/3 = 1/3
Calculation:
2/3 - 1/3 = (2 - 1) / 3
= 1 / 3
Explanation:
To calculate the fraction of the cake Elisa ate, we need to subtract 1/3 from 2/3. First, we need to find a common denominator for both fractions. In this case, the common denominator is 3. Then, we need to subtract the numerator of the second fraction, which is 1, from the numerator of the first fraction, which is 2. The difference is 1, which is the numerator of the fraction that represents the amount of cake Elisa ate. The denominator is 3, so the fraction that represents the amount of cake Elisa ate is 1/3.

Work out the total amount Glen has to pay.Povinná odpověď. Jednořádkový text.
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Maths.
Cost of each ticket = £54
Glen purchased tickets= 4
total cost of tickets alone = 54*4 =£216
now calculation of the 5% tax of the tickets,
5/100 * 216 = £ 10.8
hence the total amount Glen has to pay is
=> 216+10.8 = £226.8

Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is [tex]a^{2} + b^{2} =c^{2}[/tex], you already have the [tex]c^{2}[/tex] and another side which can be [tex]a^{2}[/tex] or [tex]b^{2}[/tex].
Because you have the hypotenuse and a side , your equation looks like this now: [tex]7^{2} +b^{2} = 25^{2}[/tex]
and when you solve for be you just subtract [tex]25^{2} -7^{2}[/tex] to get 24.

A pipe leaks water at a rate of 48 fl oz
every 5 min.
At this rate, how many gallons of water leak from the pipe in an hour? (1
gal = 128 fl oz)
The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.
What is conversion?Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
A pipe leaks water at a rate of 48 fl oz every 5 min. Then the rate is given as,
Rate = 48 / 5 fl oz per minute
We know that 1 gal = 128 fl oz, then we have
Rate = (48 / 128) / (5 / 60)
Rate = (48 x 60) / (128 x 5)
Rate = 2880 / 640
Rate = 4.5 gallons per hour
The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.
