Answer:

207

Step-by-step explanation:

Answer:

The distance between P and Q is 54

Step-by-step explanation:

We are given that triangle RPQ is similar to triangle RTS.

Property of similar triangle: The ratio of any pair of corresponding sides is the same.

So, by property : [tex]\frac{RP}{RT}=\frac{PQ}{ST}[/tex]

PR=42

PQ=x

ST=36

RT=28

So,[tex]\frac{42}{28}=\frac{x}{36}[/tex]

[tex]\frac{42 \times 36}{28}=x[/tex]

54=x

Hence the distance between P and Q is 54

Answer:

No of Monthly payments it would take to pay off his credit card = $94.601 per month

Step-by-step explanation:

If Ramiro made monthly payments at the end of each month, how long would it take to pay off his credit card?

No of Monthly payment it would take to pay off his credit card = nper(rate,pmt,pv,fv)

No of Monthly payment it would take to pay off his credit card = nper(18.24%/12,10,-500,0)

No of Monthly payment it would take to pay off his credit card = $94.601 per month.

Answer: 7/16

Step-by-step explanation:

Vowels: A, E, I, O, and U.

Number of Vowels in the phrase: "Do not run on Ichiro": 7

Now the total numbers of letters in the Phrase "Do not run on Ichiro": 16

For probability it is selected amount/  total amount

So 7/16, and this fraction is in its most simplified (reduced) form.

If this helped please mark me brainliest  

The probability is [tex]7\div 16[/tex]

Vowels: A, E, I, O, and U.

Number of Vowels in the phrase: "Do not run on Ichiro": 7

Now the total numbers of letters in the Phrase "Do not run on Ichiro": 16

So, the probability is the same.

Answer:

162

Step-by-step explanation:

Since the ratio is 3, the terms are 3 times the term before.

So the answer is 2*3^4 = 162

Answer:

l=30ft

h=10ft

Step-by-step explanation:

Area 'A' is defined as the product of length and height

[tex]A=lh=300ft^2\\h= \frac{1}{3} l[/tex]

[tex]\\300=l( \frac{1}{3}l)\\300=\frac{1}{3} l^{2}\\900=l^{2}\\30=l\\l=30ft\\\\h= \frac{1}{3}(30)\\h=10ft[/tex]

Thus,  the length and the height of the wall is 30 ft and 10 ft respectively.

Answer:

10

Step-by-step explanation:

F + V − E = 2

Where F is the number of faces, V is the number of vertices and E is the number of edges

F + 16 - 24 = 2

Combine terms

F -8 = 2

Add 8 to each side

F -8+8 =2+8

F = 10

Answer:

6 blue marbles

Step-by-step explanation:

Given;

Total number of marbles N = 15

probability of randomly selecting a green marble

P(G) = 1/5

The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25

P(G∩B) = P(G) × P(B)

P(B) = P(G∩B) ÷ P(G)

The probability of selecting a blue marble

P(B) = 2/25 ÷ 1/5 = 2/5

The number of blue marbles N(B) = P(B) × N

N(B) = 2/5 × 15 = 6

There are 6 blue marbles

Answer:

9000 sec.

Step-by-step explanation:

There are 60 sec in an hour and 60 sec in a min:

60 × 60 = 3600

Multiply 3600 to 2.5:

3600 × 2.5 = 9000

Therefore, there are 9,000 sec in 2.5 hrs.

Answer:

$2,874.25 Canadian dollar

Step-by-step explanation:

The first thing to do here is to calculate the amount of the commission.

That would be 2.2% of €2,000

= 2.2/100 * €2,000 = €44

Now the total cost to pay = selling price + amount in commissions = €2,000 + €44 = €2,044

But we need our answer in the Canadian dollars

Mathematically;

$1 Canadian = €0.711142

$x Canadian = €2,044

x = (2,044 * 1)/0.711142

x = 2,874.25014975912

This is approximately $2,874.25 Canadian dollar

Every line on the graph is 1/2 unit.

When y = 0, x would be -0.25 and 1.25

When y = 2, x would be -0.5 and 1.5

Answer:

the transitive property of uniformity reveals to us that on the off chance that we have two things that are equivalent to one another and the subsequent thing is equivalent to a third thing, at that point the primary thing is additionally equivalent to the third thing. The recipe for this property is in the event that a = b and b = c, at that point a = c.

I have attached the definition below with an example too.

Answer:

1832 miles

Step-by-step explanation:

First we need to find the angle between the routes of the planes.

If one is N30°W and the other is S45°W, we can find the angle between the routes with the following equation:

30 + angle + 45 = 180

angle = 105°

Then, we need to find the distance travelled by each plane, using the formula:

distance = speed * time

The time is 1.5 hours, so we have that:

distance1 = 800 * 1.5 = 1200 km

distance2 = 750 * 1.5 = 1125 km

Now, to find the distance between the planes, we can use the law of cosines:

distance^2 = 1200^2 + 1125^2 - 2*1200*1125*cos(105)

distance^2 = 3356214.43

distance = 1832 miles

Answer:

√41 units

Answer:

√ [41]

Step-by-step explanation:

Determine how much x and y each change, and then apply the Pythagorean Theorem to find the length of the hypotenuse (which is also the desired distance between the two points):

Moving from (-7, -9) to (-3, -4), x increases by 4 and y increases by 5.

Thus, the length of the hypotenuse / distance between the two points) is

d = √ [4² + 5² ] = √ [41]

Answer:

3n + 6

Step-by-step explanation:

So the simplified version is 3n + 18

3n + 6 X

3n + 18 = 3n + 18

2n + 8 + n + 10 = 3n + 18

2(n + 6) + 6 + n = 3n + 18

All of them except the first are EQUIVALENT.

Answer:

3n+6 is not equivalent.

Answer:

smaller

Step-by-step explanation:

If Andre is using a scale of 1:12 then we can safely say that the courtyard drawing will be smaller than his first drawing. This is because this scale means that for every 12 units of measurement on the original the newer version will be 1 unit of measurement. Therefore making the new drawing 12 times smaller than the first one that Andre made.

b^ (7*-3) / 4^(5*-3)

b ^ -21 / 4 ^ -15

We know that a^ -b = 1/ a^b

Answer: $23,600. ; $318,600

Step-by-step explanation:

From the question, we are informed that a house on the market was valued at $295,000 and after several years, the value increased by 8%.

The value of the increase will be 8% of $295,000. This can be mathematically written as:

= 8% of $295,000

= 8/100 × $295,000

= 0.08 × $295,000

= $23,600

The current value of the house will be:

= $295,000 + $23,600

= $318,600
