Answer:
Step-by-step explanation:
There is a relationship if you have two lines intersecting a circle and forming an angle outside of it. In this instance. There is a large arc, a small arc and the outside angle. The relationship is (L-S)/2 = A, so large arc minus small arc all over 2 equals that outside angle.
In this case the outside angle is U, the small arc is RT and the large arc is RS. It gives us RS but we need RT. There is another relationship to know, and that is that of an inscribed angle. Or in other words if an angle is made inside a circle and the two lines touch the circle at two other points. We have that here with angle S being an inscribed angle and making the arc RT, what we need to find.
The relationship for an inscribed angle is the inscribed angle = .5* arc angle. So we can find the arc angle RT.
If we call the arc angle A and the inscribed angle I we can rewrite what I put before as I = .5A and then as I/.5 = A since we want to find the arc. This can also be written as 2I = A
U = (SR-RT)/2
U = (SR - 2*S)/2
U = (82 - 2*22)/2
U = 19
If you want further explanation onto how the relationships I described worked I'd be happy to explain or perhaps link a video.
Answer: p = 1/25
Step-by-step explanation:
Ok, you know that the probability of rolling a six is p = 1/5
now, if you want to have two sixes, then you have two events with a probability of 1/5.
And as you know the joint probability for two events is equal to the product of the probabilities, then the probability of rolling two sixes is:
p = (1/5)*(1/5) = 1/25.
Marguerite is going to need 4 pieces of wood because...
1 piece= 6m which =600cm
She needs 78 pieces of 29cm78x29=2262
then divide 2262 by 600 and that gives you 3.77.
You cant have 3.77 pieces of wood so you have to round to 4.
Answer:
3 1/10 or 31/10
Step-by-step explanation:
The on is in the tenths place making the fraction out of ten.
The number of miles for which the car has been driven if one paid $122.50 as in the task content is; 2.5 miles.
<h3>For how many miles was the car driven?</h3>
It follows from the task content that the total amount paid was; $122.50.
Hence, after subtraction the constant charges, for the day and for gas, the remainder is;
$122.50 - $50 - $35
= $37.50.
Ultimately, if the charge per mile is $15, then the number of miles driven is; $37.50/$15
= 2.5 miles.
