Answer:
#1 is 30 degrees
#2 is obtuse
#3 is "No rhombuses are rectangles"
#4 is D
#5 is A
Step-by-step explanation:
For #1, we have an angle vertical to 120 degrees which includes a right angle, so we make an equation:
90+x=120
x=30
So angle x is 30 degrees aka. Option A
For #2, obtuse angles have the sum of the square of the side lengths that are less than the square of the hypotenuse. In this case, 6^2+4^2<9^2 or 50<81
For #3, rhombuses have two pairs of congruent sides but no right angles while rectangles have two pairs of congruent sides but they also have right angles.
For #4, they are similar because one of the triangles is dialated by a scale factor of 1.5.
For #5, just think of turning the triangle on its other side, aka. option A
Answer:
245.04
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·10+2·π·32≈245.04423
u have to divide 6 and 2 to find the radius
hope this helps
Answer:
5:8
Step-by-step explanation:
the ratio equivalent to 5 / 8 is 5:8
You will need to multiply 2.25 by 375.5 which will then give you 844.87 but if we round it the answer will be 844.9
0.999999999... indeed can be 1.
Same as 0.33333... is equal to 1/3. Though you can see it's a fraction.
Same thing is basically with 0.99999... to 1. It's just the fact that the 1 is a whole number but the 0.9999... looks messy.
The terms of the associated sequence 0.9, 0.99, 0.999,..., do "get arbitrarily close" to 1, in the sense that, for each term in the progression, the difference between the term and 1 gets smaller and smaller.
The number 0.999... (with the ellipse) means that it goes on forever, there is no stop to it meaning that it basically is, and has been proven, that it is 1.
Hope this helps :)
