Answer:
To prove the relationship about the length of a midsegment, I can use the properties of parallel lines and transversals. If I draw at least two midsegments, I see that they form congruent triangles within the original triangle, ∆ABC. I can prove the congruence of these triangles using triangle congruence criterion, and then use properties of congruent triangles and the Transitive Property to show that the length of the midsegment is half the length of the side it is parallel to.

m > 5m-4
Pls solve and show steps hurry pls !!!!
Answer:
move 5m over the sign so it is like this m-5m>-4 subract it will be-4m>-4 divide both sides by-4 m=1 negative divided by a negative is a positive
the answer is m<1
I subtracted 5 from both sides to get m-5m>-4
I simplified it to -4m>-4
divided both sides by -4 and got m<1 as the answer

You are researching the average emails received per day. You want to know how many employees you should survey if you want to know, at a 90% confidence level, that the sample mean emails per day is within 47 emails of the true mean emails per day. From above, we know that the population standard deviation is 155, and z-value is 1.645$_
Answer:
The value is [tex]n =29 \ employees [/tex]
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
[tex]n = [ \frac{z * \sigma }{E} ]^2[/tex]
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for [tex] \sigma[/tex]
[tex]n = [ \frac{1.645 * 155 }{47} ]^2[/tex]
=> [tex]n =29 \ employees [/tex]

You play a game on your phone. For every correct move you make you recieve 50 points. For
every second that it takes you to complete the game you lose 3 points. You complete the game
in 2 minutes and 12 second using 30 correct moves. What is your score?
a) Write the expression used to solve the problem?
b) What is your score?
Answer:
A it is addition
B it is 97
Answer:
1,104 points
Step-by-step explanation:
First I figured out how many seconds it took to finish the game (132)
Then I figured out how many points he got by multiplying 30x50=1,500
After that, I multiplied 3 and the number of seconds that it took to finish the game (3x132) and that gave me the answer of 1,104 points

20. Matt is selling chocolate bars to make some extra money. In the first week of selling, he sold 2x2 + 3x − 1 chocolate bars. In the second week of selling, he sold 3x2 − 2x + 3 chocolate bars. If x = 2, how many chocolate bars did he sell in total over the two weeks?
Answer: 24
Step-by-step explanation:
Chocolate bars sold in first week:
= 2x² + 3x − 1
where x = 2
= 2x² + 3x − 1
= 2(2)² + 3(2) − 1
= (2×4) + 6 - 1
= 8 + 6 - 1
= 13
Second week
= 3x² - 2x + 3
= 3x² - 2x + 3
= 3(2)² - 2(2) + 3
= 12 - 4 + 3
= 11
Total chocolate sold = 13 + 11 = 24

hope that's it
Hi!
I can help you with joy!
No worries, we can solve this inequality easily. :)
First of all, let's use the Distributive Property and distribute 2:
[tex]\rm{2(x+5)>8[/tex]
[tex]\rm{2x+10>8[/tex]
Now, move 10 to the right, using the opposite operation:
[tex]\rm{2x>8-10[/tex]
Subtract:
[tex]\rm{2x>-2[/tex]
Final Step: Divide both sides by 2.
[tex]\rm{x>-1[/tex] (Answer)

Answer:

Step-by-step explanation:
To find the length of web we can use the Pythagoras theorem. In order to find the length of web, we first need to find the length between the corners of the 6 feet length and the 10 feet length. This is because the Pythagoras theorem requires a right-angled triangle, which we can form using 8 as the shortest side, the bottom diagonal as the 2nd side and the strand of web as the hypotenuse.
To find the bottom diagonal we first need to use the lengths of 6 and 10 to use the pythagoras theorem.
[tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]6^{2} +10^{2} =c^{2} \\36+100=c^{2} \\136=c^{2}\\\sqrt{136} =c\\c=11.662[/tex]
(3dp)
Now that we have found the length of the bottom diagonal to be 11.662, we can use this length and the 8 we are given to find the strand of web.
[tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]11.662^{2} +8^{2} =c^{2} \\136+64=c^{2}\\200=c^{2}\\\sqrt{200} =c\\c=14.14[/tex]
Rounded to nearest 10th is 14.1

-10 = -b/4
solve for b, show steps please
Answer:
b = 40
Step-by-step explanation:
-b/4 = - 10 Multiply both sides by 4
-b/4 * 4 = - 10 * 4
- b = - 40 Multiply both sides by -1
(-1) * (-b) = (-40)(-1)
b = 40

Customers of a phone company can choose between two service plans for long distance calls. The first plan has an $18 monthly fee and charges an additional $0.08 for each minute of calls. The second plan has a $10 monthly fee and charges an additional $0.12 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
The costs of the two plans would be equal with 200 minutes.
Step-by-step explanation:
From the information given, you can write the following:
18+0.08x=10+0.12x, where x is the number of minutes of calls
Then, you can solve for x:
18-10=0.12x-0.08x
8=0.04x
x=8/0.04
x=200
According to this, the answer is that the costs of the two plans would be equal with 200 minutes.
what is the distance between -3/7 and 2/8
Answer:
[tex] \frac{19}{28} [/tex]
Step-by-step explanation:
distance between -3/7 and 2/8
[tex] = \frac{2}{8} - \bigg( - \frac{3}{7} \bigg) \\ \\ = \frac{2}{8} + \frac{3}{7} \\ \\ = \frac{2 \times 7}{8 \times 7} + \frac{3 \times 8}{7 \times 8} \\ \\ = \frac{14}{56} + \frac{24}{56} \\ \\ = \frac{14 + 24}{56} \\ \\ = \frac{38}{56} \\ \\ = \frac{19}{28} [/tex]
whats 2+34233-2943+291*45=
what the anwser??????????????
Answer:
44387
Step-by-step explanation:
Answer:
1421235
Step-by-step explanation:
2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 x 45 = 1421235
2 + 34233 = 34235 - 2943 = 31292 + 291 = 31583 ➗ 45 = 701.844444444
If its multiplication the answer is = 1421235
If division the answer is = 701.844444444 (calculator) or 701 r 38 (my brain)
Question: 11.23 x 10 to the power of 5, the answer is 11.2300000.
Explanation: multiple 10 x 10 x 10 x 10 x 10 = 10,000, then multiple 11.23 x 10,000 = 112300000, add the decimal places = 11.2300000.
Question: 11/20 a repeating or terminating decimal,
Answer: is terminating.
Question: 7 * 73 + 43, the answer is 554.
Explanation: multiple 7 x 73 = 511 + 43 = 554. If division then divide 7 into 73 = 10.4285714286 + 43 = 53.4285714286 (calculator answer). 7 into 73 = 1 r 3 = 1.3 + 43 = 44.3 or 44 r 3 (my brain answer).
