THIS IS AN EMERGENCY PLEASE HELP ME!!!!!!!!!!!!!

When the original price and discounted prices are known, how can we find the percent markdown? Explain please.

Answer:

6 vans and 6 buses

Step-by-step explanation:

v+b=12 this equation represents the amount of vehicles

6v + 55b = 366 this equation represents the amount of students per vehicle.

after solving you get v=6 and b=6

Answer:

11

Step-by-step explanation:

The required distance left to the walk will be 11 km.

The percentage is defined as a ratio expressed as a fraction of 100.

Let the total distance of the walk would be x km

As per the given information, the required solution would be as:

⇒ 45% of x = 9

45%  is expressed as 45/100 in fractional form

⇒ (45/100)x = 9

45/100  is expressed as 0.45 in decimal form

⇒ 0.45x = 9

⇒ x = 9/0.45

⇒ x = 20

So the total distance of the walk is 20 km

Since he has already walked 9 km.

So, he has left to the distance of the walk = 20 - 9 = 11 km

Therefore, the required distance left to the walk will be 11 km.

Answer:

R= {7, 11, 15}

Step-by-step explanation:

Since we already know what the Domain is for f (2, 4, 6) we can use that to get the range

Since the domain is also x let's replace x for 2

y=2(2)+3= 4+3=7

One of the range is 7

Replace x for 4

y=2(4)+3= 8+3= 11

One of the other range is 11

Replace x for 6

y= 2(6)+3= 12+3= 15

The last range is 15

So the range is R= {7, 11, 15}

The value of x is 150°. The correct option is D. 150°

From the question, we are to determine the measure of angle x

In the given diagram, we can observe that  

The angle supplementary with x is 30° (Alternate angles theorem)

Thus,

x + 30° = 180° (Supplementary angles)

x = 180° - 30°

x = 150°

Hence, the value of x is 150°. The correct option is D. 150°

Answer:

4266

Step-by-step explanation:

Okay! let's start with finding what 3% of 5400 birds is

3% is .03 as a decimal. We can find 3% of 5400 by multiplying 5400 by .03

5400×.03= 162

If our rainforest is losing 3% a year, that means we are losing 162 birds a year.

Let's turn it into an equation! x will be the number of years

5400-162x= number of birds left after x years

Now put 7 in for x

5400-(162×7)= 4266 birds

Hope this helps!

Step-by-step explanation:

Step 1: Define

3.6y = 1.6y + 24

Step 2: Solve for y

Step 3: Check

Plug in y into the original equation to verify it's a solution.

Here we have 43.2 does indeed equal 43.2.

∴ y = 12 is the solution to the equation.

Answer: 75%

Step-by-step explanation:

The debt went from $1,600 to $400.

Formula when calculating percent decrease is:

= (New price - old price) / Old price

= (400 - 1,600) / 1,600

= -75%

Answer:

Option C

Step-by-step explanation:

Segment addition postulate states that "if a point Q lies on a segment joining two points A and B, then AQ + BQ = AB"

By this postulate,

AQ + BQ = AB

BP + PC = BC

Since, BP ≅ BQ and PC ≅ QA

Therefore, BP + PC ≅ BQ + QA

BC ≅ AB

Option (C) will be the answer.

Answer:

Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit

Step-by-step explanation:

As given, Jessica's initial deposit = $100

                Tyshaun initial deposit = $ 100

As given, Tyshaun account earns 2.5 percent interest compounded annually.

rate = 2.5% = 0.025

so, after t= 10 years

Payment = P[tex](1+r)^{t}[/tex] = 100[tex](1+0.025)^{10}[/tex] = 100[tex](1.025)^{10}[/tex] = 128.01

So ,

Interest = Money earned by Tayshaun - Jessica's initial deposit

            = 128.01 - 100

            = 28.01

∴ we get

Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit
