If X || Y and Y || Z, then
Answer:
X || Z
Step-by-step explanation:
Step-by-step explanation:
well, what does your own logic tell you ? just think logically.
of course it is X || Z.
what else could it be ?
this is similar to questions like
if A > B, and B > C, then what does that say about A and C ?
right, A > C.
same thing for A=B, B=C, then A=C.
but it does not work with every relationship. so, be careful and just use basic logic - but that you will have to use.

Alexa used some ribbons to make 4 headbands and a bracelet. She used 4.95 cm of ribbon for each head band and 4.24 cm for the bracelet. How many centimeters of cloth did she use altogether?
Answer:
24.04 cm
Step-by-step explanation:
each headband uses 4.95cm and each bracelet uses 4.24cm.
4 headbands * 4.95 cm = 19.8cm
1 bracelet * 4.24 cm = 4.24 cm
19.8 cm + 4.24 cm = 24.04 cm

Answer:
Option A
Step-by-step explanation:
We know that the "3x ? 2" line must be positive, so it cannot be C or D. The other line is negative, so the "2x ? 5" line must be -2x. This gets rid of option B, leaving us with our answer of A!

Angie has 12 3/4 yards of fabric to make Halloween costumes. Each fabric costume requires 7/8 yards of fabric. How many costumes can Auntie make?
Since Angie has 12 3/4 yards of fabric and all and each costume requires 7/8 yards, you can divide 12 3/4 by 7/8.
12 3/4 ÷ 7/8
= 51/4 ÷ 7/8
= 51/4 • 8/7 (remember that dividing by a fraction is the same thing as multiplying by it’s reciprocal)
= 51/1 • 2/7 (after simplifying)
= 102/7
= 14 4/7
Angie can make 14 costumes. She cannot make the 15th one because she’ll run short of fabric.

The lifespans of seals in a particular zoo are normally distributed. The average seal lives 13.8 years; the standard
deviation is 3.2 years.
Use the empirical rule (68 - 95 - 99.7%) to estimate the probability of a seal living less than 7.4 years.
Answer:
67.715
Step-by-step explanation:
(68 - 95 - 99.7%)
2. A scuba diver dove 48 feet in 4 minutes.
What integer represents his change in depth
for each minute?
A. 52 feet per minute
B. 44 feet per minute
C. -12 feet
per
minute
D. -48 feet per minute
Answer:
C. -12 feet per minute
Step-by-step explanation:
This question is really just asking for the slope of this situation. So the best way to find the answer is to find the change in y over the change in x. In this case, y is the depth and x is the time. So, it would be -48/4 because the diver went down 48 feet when 4 minutes passed. Then, simply divide, -48/4, which equals -12 feet/1 minute.
