I have to show my work using the LCM strategy or fraction models.
Answer:
1/2 or 0.5 in decimal
Step-by-step explanation:
you would want to make the 3/10 eqale to 20/100 like it has to have the same denominatior which is 10x10 and 3x10. because 10x10 eqal to 100, and what you do to the bottom you have to do the same on the top. and then you add which becomes 30/100+20/100=50/100 and 50/100 =1/2 if you simplfiy.
2m+(m-15)=90 solve for m
Answer:
m = 35
Step-by-step explanation:
2m + m -15 = 90
3m -15 = 90
+15 +15
3m = 105
/3 /3
m = 35
To check the work just insert 35 for m:
2(35) + 35 -15 = 90
70 + 35 -15 = 90
105 - 15 = 90
90 = 90

Answer: The given expression (3x − 5) − (4x + 6) = -x - 11.
Step-by-step explanation:
Given : Expression (3x − 5) − (4x + 6).
We have to simplify the given expression.
Consider the given expression (3x − 5) − (4x + 6).
Remove Parentheses ,
we have,
(3x − 5) − (4x + 6) = 3x - 5 - 4x -6
Combining like terms, we have,
LIKE TERMS are terms having same variable with same degree.
here 3x and -4x are like term and -5 and -6 are like terms,
Simplify, we have,
= 3x - 4x - 5 - 6
= -x - 11
Thus, the given expression (3x − 5) − (4x + 6) = -x - 11.
Step-by-step explanation:

3. A manufacturing process produces integrated circuit chips. Over the long run, the fraction of bad chips produced by the process is 20%. Thoroughly testing a chip to determine whether it is good or bad is rather expensive, so a cheaper test is used. All good chips will pass the test, but so will 6% of the bad chips. a) (4 points) What is the probability that a randomly chosen chip will pass the test
Answer:
0.812 = 81.2% probability that a randomly chosen chip will pass the test
Step-by-step explanation:
Over the long run, the fraction of bad chips produced by the process is 20%.
So 100 - 20 = 80% are good.
All good chips pass the test, while 6% of the bad chips(20%) also pass.
a) (4 points) What is the probability that a randomly chosen chip will pass the test
[tex]p = 0.8 + 0.06*0.2 = 0.812[/tex]

Answer:
m<ABC = 116°
m<CDE = 67°
Step-by-step explanation:
✔️m<ABC = 180 - m<BAD (adjacent angles of a parallelogram are supplementary)
m<ABC = 180 - 64° (Substitution)
m<ABC = 116°
✔️m<CDA = m<CDE + m<ADE (angle addition postulate)
m<CDA = m<CDE + 49°
m<CDA = m<ABC (opposite angles of a parallelogram are congruent)
m<CDE + 49° = 116° (substitution)
m<CDE = 116° - 49° (Substraction property of equality)
m<CDE = 67°

After spending many hours studying for your math class, you decide to reward yourself with a case of cream soda. Unfortunately, Corner Market only had a warm case left. You buy several bags of ice and decide to chill it at home. When you get home, the temperature of the soda is 76° F, and you proceed to pack it in ice. After 10 minutes, the temperature cooled to 70° F. If cream soda is best served at 60° F or cooler, how much longer must you wait to enjoy your chilled cream soda?
Answer:About sixteen minutes.
Step-by-step explanation: After you find out that Ten minutes is six degrees you divide ten by six and get 1.666. Then you multiply that by the time remaining and get 16 minutes rounded. or seventeen if you are specific.
A line has a slope of -1/10
and includes the points (1, -6) and (t, -5). What is the value of t?
Answer:
-9
Step-by-step explanation:
Here we use the slope formula: m= y2-y1/x2-x1. We simply plug in the numbers we know: -1/10 = -5+6/t-1. Then we solve for t. Multiply both sides by (t-1) so -1/10 (t-1)= 1. Then multiply both sides by -1/10 so t-1= -10 and then add one to both sides so t=-9.

Find sin D and sin E. Write each answer as a fraction and as a decimal. Round to four decimals places.
Answer/Step-by-step explanation:
✔️Sin D = opp/hyp
Opp = 12
Hyp = 15
Sin D = 12/15 = 4/5 (as fraction )
Sin D = 0.8 (as decimal)
✔️Sin E = opp/hyp
Opp = 9
Hyp = 15
Sin E = 9/15 = 3/5 (as fraction)
Sin E = 0.6 (as decimal)

Item 20 Two groups leave on different flights from the same airport. Group A flies 130 miles due west, then turns 24° toward north and flies 45 miles. Group B flies 130 miles due north, then turns 32° toward east and flies 45 miles. Which group is farther from the airport?
Answer:
Group A
Step-by-step explanation:
Since in total they moved the same amount of miles then the one with the least turnback (angle in this case) would be farther
