The true statements are ∠M≅∠Q, QK¯¯¯¯¯¯≅MJ¯¯¯¯¯¯ and MN¯¯¯¯¯¯¯≅QR¯¯¯¯¯.
In order to determine these, we need to note that where the letter is listed in the original statement determines its congruency. Because they are both first J and K are always the same. This is the same for the ones in the middle (M and Q) and the ones at the end (K and J).
So as an example MN¯¯¯¯¯¯¯≅QR¯¯¯¯¯ is true because MN involves the middle and then first term. QR does the same and is therefore congruent.
Answer:
Step-by-step explanation:
It is convenient to use the variables "a" and "c" for the number of adult tickets and child tickets, respectively. Two equations using these two variables can be written based on the given information:
7a +5c = 350 . . . . total revenue from ticket sales
a - c = 10 . . . . . . . . 10 more adult tickets were sold
_____
<em>Comment on the question</em>
The solution to these equations is a=33 1/3; c=23 1/3. There is no integer solution. In real-world terms, the given relations cannot exist.
The constant π is defined as the ratio of the circumference of a circle with respect to its diameter, mathematically:
π=C/d which can be rearranged to
C=πd
Since the diameter is equal to twice the radius of the circle, ie d=2r
C=2πr dividing both sides by 2π gives you:
r=C/(2π), the "spoke" in our problem is equal to the radius of a circle, and we are told that C=42in so:
r=42/(2π) in
r=21/π in
r≈6.68 in (to nearest hundredth of an inch)
Answer:
the volume at 606k is 2.22....the third one
Step-by-step explanation:
v1=1.00 t1=273 v2=? t2=606
v1/t1=v2/t2
1.00/273=v2/606
1.00×606=273v2
606=273v2
606/273=v2
2.21 L=v2
Answer = 2.96789 * 10 to the 9th power
