There are not right angles within the triangle so you can eliminate option b. The angles are less than 90 degrees as they arent even cloe to being a right angle so they arent obtuse so you can eliminate option d. Now you are only left with option a.

URGENTT!! Susan will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.60 per mile driven. The second plan has an initial fee of $75 and costs an additional $0.10 per mile driven. How many miles would Susan need to drive for the two plans to cost the same?

Answers

Answer:

150 miles

Step-by-step explanation:

Let

x = number of miles

Plan A: 0.60x

Plan B: 75 + 0.10x

How many miles would Susan need to drive for the two plans to cost the same?

0.60x =75 + 0.10x

0.60x - 0.10x = 75

0.50x =75

x = 75/0.50

x = 150 miles

Susan needs to drive for 150 miles for the two plans to cost the same

Answers

Answer:

This illustrates a right triangle.

Given:

a(height) = 2457 ft.

∠A = 22°23' ; which is the elevation and reflects the a(height)

Find:

b(base)

Solution:

Using the law of cosine, specifically tan∠ = opposite side÷adjacent side

By analysis, tan∠A = a÷b

Since we are finding b, the formula will be derived into:

b = a÷tan∠A

Find b(base):

b = 2457 ft. ÷ tan22°23' ; substituting the numbers

b ≈ 5,966.05 ft. ; Final Answer

You and a friend go to surf taco for lunch. you order 3 soft tacos and 2 burritos and your total bill is 25. Your friend bill is 30 for 5 soft tacos and 2 burritos. How much do soft tacos cost? 3x+2y=25 4x+2y=30 X-soft tacos y-burritos​

Answers

Answer:

Step-by-step explanation:

Let the cost of one soft taco = s

Let the cost of one burrito  = b

 

So  we have this system

 

3s  + 3b  = 11.25  

4s +  2b   = 10.00   (1)

 

Divide  the first equation through by 3   and we have that

 

s +  b  =  3.75         subtract  b from both sides

s   =  3.75 - b   (2)

 

Sub  (2) into (1)  and we have

 

4 (3.75 - b)  +  2b  =  10.00      simplify

15 - 4b  + 2b   = 10.00

-2b + 15  =10.00      subtract 15 from both sides

-2b  =  - 5.00         divide both sides by -2

b  = 2.50

 

And using (2)

s  =  3.75 - 2.50   =   1.50

 

 

So...  a soft taco  1.50 and a burrito is  2.50

A comet passes Earth every 70 years. Another comet passes Earth
every 75 years. If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?

Answers

Answer:

1,050 years

Step-by-step explanation:

A comet passes Earth every 70 years.

Another comet passes Earth

every 75 years

If both comets pass Earth this year, how many years

will it be before they both pass Earth on the same year again?

Find the lowest common multiple of 70 years and 75 years

70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,

75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350

Lowest common multiple of 70 years and 75 years is 1,050 years

Therefore,

If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

12. Solomon scored 88% on his math test. If the test had 25 questions total, how many
questions did Solomon miss?

Answers

Answer:

He missed 3 questions (which is a score of 22/25 that equals 88%)

Step-by-step explanation:

This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.

So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.

numerator : 24(15).x^5.y^8.z^7
denominator: 40(6).x^3.y^6.z^9
First, the numbers.

Then x: x^5/x^3 = x^(5-3) = x^2
Then y: y^8/y^6 = y^2
