Answer:
No congruency statement can be made because the side lengths are unknown.
Step-by-step explanation:
We are given the measure of two angles in ∆XYZ, as 90 and 30 respectively. The 3rd angle can be known without being given. Since sum of angles in a triangle is 180°, the 3rd angle would be 180 - (90+30) = 60°.
Same applies to ∆TUV.
We only know the 3 angles of each triangle, but we are not given any of the side lengths. Therefore, we cannot make any congruency statement since the side lengths are unknown.
Let's begin by calling Sarah's age now as X. As Ralph is 3 times as old as Sarah, X times 3 = 3X. Hence, Ralph's age is 3X. In six years, Ralph will be twice as old as Sarah. To calculate six years from now, add 6 to X for Sarah, and 6 to 3X for Ralph. As Ralph is twice as old as Sarah and we want to find the difference between the ages to calculate X, multiply X+6 by 2. You'll get 2X+12. Therefore, 2X+12=3X+6. Deduct 6 from 3X+6 as we want to isolate the variable. Because you did that to one side, you have to deduct 6 from 2X+12. Hence, now you have 2X+6=3X. X=6. Ralph's age is 3X, so 6 times 3 is 18. Ralph is 18 years old.
Answer: A linear relationship
Step-by-step explanation:
From the graph we can see as the number of years increasing the average price of a PC decreasing at a constant rate.
It is forming a straight line and its equation 
is similar to equation of line 
, where m= -39 which is the rate of change of average price.
Hence, the relationship between the average price of PCs and the number of years that have passed since 2000 is a linear relationship.
Answer:
Calculate the percent value:
0.942 =
0.942 × 100/100 =
(0.942 × 100)/100 =
94.2/100 =
94.2%;
In other words:
1) Multiply that number by 100.
2) Add the percent sign % to it.
Answer:
0.942 = 94.2%
Step-by-step explanation:
B: 250
75 divided by 6 is 12.5 meaning lebron earned 12.5 points each game so..
12.5 multiplied by 20 is 250
