Answer:
361-176=185
Step-by-step explanation:
Answer:
-185
Step-by-step explanation:
176-(-185)= 361
two negatives equal a positive.
so the negative becomes a positive, the "-(-" becomes "+"
so new equation is 176+185= 361

Which triangles are SAS, SSS or not possible? HURRY!!!
Answer: 1 is not possible, 2 is SAS, and 3 is SSS
1 is AAA, which is not a triangle congruency theorem, thus not possible.
The markings on 2 display two congruent sides with a congruent angle between, and is thus SAS.
3 shows two congruent side markings and a shared side length, thus 3 sides are congruent (SSS).
Write two numbers which his greatest common divisor is 210 and to be between 10000 and 11000
Answer:
10080, 10290
Step-by-step explanation:
The multipliers of 210 required will be mutually prime integers that satisfy ...
10000 ≤ 210n ≤ 11000
47.61 ≤ n ≤ 52.38
That is, you want a pair of integers, each between 48 and 52, that have no common factors. Possibilities include ...
(48, 49), (49, 50), (49, 51), (49, 52), (50, 51), (51, 52)
For the above numbers, we have chosen ...
48×210 = 10,080
49×210 = 10,290

Mia is 7.01568 x 10^6 minutes old. Convert her age to more appropriate units using years, months, and days. Assume every other month has 30 days, instead of 31.
Answer:
There are 13 years 6 months and 12 days.
Step-by-step explanation:
Let's convert the scientific notation to standard form of minutes
7.01568x10^6 =7015680 minutes
Now, let's convert this to number of days because each day has 24*60=1440 minutes.
So, number of days in 7015680 minutes is [tex]\frac{7015680}{1440}[/tex]=4872 days
Now, change this 4872 days to years, months and days.
We know 1 year has 12 months and one month has 30 days.
So,
Number of years =[tex]\frac{4872} {12*30}[/tex]=13.53333333 years
Now, convert 0.53333333 years to months.
0.53333333*12=6.4 months.
Now, convert 0.4 months to days.
0.4* 30 =12 days.
So, there are 13 years 6 months and 12 days.

Answer:
3x³ + 23x² + 63x + 55
Step-by-step explanation:
Given
(3x + 5)(x² + 6x + 11)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis

As we can see that common difference is increasing to one more digit after every term
so it means
a21 = 231
Answer:
1. a_n = a_(n-1) + n where a_1 is 1 or a_n = n(n+1)/2
2. 231
Step-by-step explanation:
Notice that from 1 to 3, you add 2; from 3 to 6, you add 3; from 6 to 10, you add 4, etc. The pattern here is add 2, add 3, add 4, add 5, etc.
1. Let the nth term be a_n. The recursive equation can be written as a_n = a_(n-1) + n where a_1 = 1 (Use this because they most likely teach you this in schools)
Here is it written in an arithmetic equation (most likely not taught in school):
We can write an arithmetic expression using the summation formula because it is basically the sum of the numbers from 1 to n, so a_n = n(n+1)/2
2. Using the recursive, we would need to constantly add until you get up to a_21, which would take a while. Using the arithmetic equation, we can simply get:
21(21+1)/2 = 21(11) = 231

3. The total cost after tax to repair Deborah's computeris represented by 0.08(507) + 50h, where h represents
the number of hours it takes to repair Deborah's computer. What part of the expression represents the
amount of tax Deborah has to pay? Explain.
Answer:
The part of the expression representing the amount of tax to be paid is;
0.08(507)
Step-by-step explanation:
Here, we want to select the part of the expression that represents the amount of tax Deborah has to pay
From the expression, we have ;
0.08(507) + 50h
Kindly note that we can have 0.08 as 8/100
8/100 is same as 8%
when we represent taxes, it is usually a percentage of something
In that case, the tax part would be ; 0.08(507)
