Step-by-step explanation:
Please Help!! Angles A and B are complementary. If the measure of angle A=3x-8 and measure of Angle B =5x+10, what is the measure is each angle?
Answer:
Step-by-step explanation:
3x - 8 + 5x + 10 = 90
8x + 2 = 90
8x = 88
x = 11
3(11) - 8 = 33 - 8 = 25 for <A
5(11) + 10 = 55 + 10 = 65 for<B

Find an expression for the number of colored border tiles needed for any N x N square center.
Answer:
8N - 4 border tiles.
Step-by-step explanation:
There are 4 border tiles in each corner and between the tiles there are N-2 tiles along the 4 sides.
So the number of border tiles
= 4+ 4(N - 2)
= 4 + 4N - 8
= 8N - 4.

What’s the answer to 1.9m + 14 = 2m?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{m = 140}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{1.9m + 14 = 2m}[/tex]
Move 2m to right hand side and change it's sign
Similarly, move 14 to left hand side and change it's sign
[tex] \dashrightarrow{ \sf{1.9m - 2m = - 14}}[/tex]
Collect like terms
[tex] \dashrightarrow{ \sf{ - 0.1m = - 14}}[/tex]
Divide both sides by -0.1
[tex] \dashrightarrow{ \sf{ \frac{ - 0.1m} { - 0.1} = \frac{ - 14}{ - 0.1}}} [/tex]
Calculate
[tex] \dashrightarrow{ \sf{m = 140}}[/tex]

If a package of gift cards has a total value of $1050 how much does the average set of 2 gifts card price at if there are 15 in a group?
Answer:
$140
Step-by-step explanation:
If a package of gift cards has a total value of $1050, the total price for 2 gift cards will be 2×$1050 = $2100
If there are 15 in an average set of 2 gift cards, the average cost of the two gift cards will be expressed as;
Total price of 2gift cards/amount of card per group.
Average cost of of 2 gift cards = $2100/15
= $140
Hence the average cost of 2gift cards if there are 15 in a group is $134
As part of their application for a loan to buy Lakeside Farm, a property they hope to develop as a bed-and-breakfast operation, the prospective owners have projected:
Monthly fixed cost (loan payment, taxes, insurance, maintenance) $6000
Variable cost per occupied room per night $ 20
Revenue per occupied room per night $ 75
a. Write the expression for total cost per month. Assume 30 days per month.
b. Write the expression for total revenue per month, first using the general variables, and second including the values of known variables).
c. If there are 12 guest rooms available, can they break even? What would be the profit with 12 rooms?
d. What percentage of rooms would need to be occupied, on average, to break even?
Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
Monthly fixed cost= $6,000
Variable cost per occupied room per night= $20
Revenue per occupied room per night= $75
First, we need to structure the total cost formula:
Total cost= 6,000 + 20*x
x= occupied room
Now, we can find the expression for total revenue:
Revenue= selling price per unit*units - fixed cost - unitary variable cost*units
Revenue= 75*x - 6,000 - 20*x
I assume that the 12 rooms will be occupied for the 30 days:
Revenue= 75*(12*30) - 6,000 - 20*(12*30)
Revenue= $13,800
Finally, we need to determine the break-even point in units:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 6,000 / (75 - 20)
Break-even point in units= 109 rooms
On percentage= (109/360)*100= 30.28%
OLGA went on an 82 mile bike trip last week by Thursday night she travel 64 miles of the total distance which president is reasonable estimate of how much of the trip OLGA completed by Thursday
Answer:Note: This symbol ≈ means approximately.
629 ≈ 600
215 ≈ 200
111 ≈ 100
588 ≈ 600
Now, we add the simplified numbers up: 600 + 200 + 100 + 600 = 1500. So, your answer is D or 1,500.

A woman making $3000 per month has her salary reduced by 10% because of sluggish sales. One year later, after a dramatic improvement in sales, she is given a 20% raise over her reduced salary. Find her salary after the raise.
Answer:
$3240 a month
Step-by-step explanation:
First, find her reduced salary:
3000(0.9)
= 2700
Then, find her salary after the raise:
2700(1.2)
= 3240
So, her salary after the raise is $3240 a month

Express the following vector in the form v vi+V2j+ v3k 3u -v if u (3,5,-8) and v (2,-5,7)
Answer:
7i+20j-31kStep-by-step explanation:
Given the vectors u (3,5,-8) and v (2,-5,7), they can also be written as;
u = 3i+5j-8k
v = 2i-5j+7k
To express the vector 3u - v in vector form, first let us find the vector 3u;
3u = 3(3i+5j-8k)
3u = 3(3i)+3(5j)-3(8k)
3u = 9i+15j-24k
Subtract v from the resulting vector.
Since v = 2i-5j+7k
3u - v = 9i+15j-24k - (2i-5j+7k)
3u-v = 9i+15j-24k -2i+5j-7k
collect the like terms
3u-v = 9i-2i+15j+5j-24k-7k
3u-v = 7i+20j-31k
Hence the vector 3u-v in the form v = vi+V2j+ v3k is 7i+20j-31k

round 737.88 to the nearest tenth place?
Answer:
737.9
Step-by-step explanation:
8 is the hundredth place in 737.88, and 8 rounds up. So, the answer is 737.9
Answer:
737.9
Step-by-step explanation:
When we round something to the nearest ___ place, we want to look to the value to the right of it.
Since we're rounding it to the nearest tenths place, we want to look at the value to the right of it - the hundredths place.
The number in the tens place will be one more if the hundredths place is 5 or greater. It will remain the same if the hundredths place is below 5.
8 is greater than 5. This means the tens place will round up to 9.
So 737.9.
