Answer:
B. <Q = <R
Step-by-step explanation:
Angles are related to their intercepted arcs. An intercepted arc is found by finding the arc segment on a circle whose endpoints connect with the segments that make up an angle.
In this case, TQ and SQ make up <Q, so TS is the intercepted arc of <Q. However, TR and SR make up angle <R as well, making TS the intercepted arc of <R as well.
This means that because the angles share an intercepted arc, they are congruent.
Answer:
c
Step-by-step explanation:
The answer is B) 1.5
To find the expected number of siblings, multiply each outcome by the probability of the outcome (0)(0.1) + (1)(0.6) + (2)(0.05) + (3)(0.15) + (4)(0.1) = 1.55 OR 1.5 siblings.
First, we need to break up the sentence as part of the equation.
Tims age in 7 years...
t + 7
in 7 years Tims age will be...
t-19
We'll end up with: t + 7 = 3(t – 19)
Answer:
20 pavers
Step-by-step explanation:
step 1
Find the area of the rectangular patio
The area of a rectangle is equal to
![A=LW](https://tex.z-dn.net/?f=A%3DLW)
we have
![L=20\ ft\\W=4\ ft](https://tex.z-dn.net/?f=L%3D20%5C%20ft%5C%5CW%3D4%5C%20ft)
substitute
![A=(20)(4)=80\ ft^2](https://tex.z-dn.net/?f=A%3D%2820%29%284%29%3D80%5C%20ft%5E2)
step 2
Find the area of one square paver
The area of a square is equal to
![A=s^2](https://tex.z-dn.net/?f=A%3Ds%5E2)
we have
---> length side of the paver
substitute
![A=2^2=4\ ft^2](https://tex.z-dn.net/?f=A%3D2%5E2%3D4%5C%20ft%5E2)
step 3
Divide the area of the rectangular patio by the area of one paver to find out the number of pavers needed
![80/4=20\ pavers](https://tex.z-dn.net/?f=80%2F4%3D20%5C%20pavers)
