Answer: q = 25 m, p = 50 m
Step-by-step explanation:
p is the length, and q is the width.Since the length is twice as long as the width, we can come up with the equation: p = 2qSince the perimeter is 150, we can also come up with this formula since the perimeter is all sides added together: 2p + 2q = 150Since we have two equations, we can just plug them into each other. First, let's substitute the 2q in the second equation with p that is defined in the first equation: 2p + p = 150If we simplify that, we get: 3p = 150Now we know that p = 50 m.Now, if you plug in 50 into the first equation you get: 50 = 2q.Next, just simplify, and you know that q = 25 m.Therefore, p = 50 m, q = 25 m.what is the value of x+7 when x=3?

A bag contains 15 marbles. The probability of randomly selecting a green marble is 1/5. The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is 2/25. How many blue marbles are in the bag?
2
3
5
6
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

A house on the market was valued at $295,000. After several years, the value increased by 8%. By how much did the house's value increase in dollars? What is the current value of the house?
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

Answer:
√41 units
Please see the attached picture for full solution
hope it helps
Good luck on your assignment
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]
what is the transitive property
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.

Sally's basic cable plan costs $55 a month and an additional $3 for each premium channel.
Cable plan B costs $60 and an additional $2.50 for each premium channel. Which plan is
cheaper if Sally wants to order 10 premium channels?
Step-by-step explanation:
Sally is paying $55 + $3×10 = $85 currently
if she switches to plan B the she will pay $60 + $2.50×10 = $85
That shows both of the cable plan costs same for monthly payment + 10 premium channels
Ramiro is also a college student. He has a credit card balance of $500.00. The APR on his card is 18.24%. His minimum payment is $10.00. (do not use commas or dollar signs in the answers)
How much will he pay in all?
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.

Step-by-step explanation:
Two planes are flying away from Toronto Pearson International Airport. The Air Canada
plane is flying with an average speed of 800 km/h in the direction of N30°W and the
British Airways plane is flying with an average speed of 750 km/h in the direction of
545°W. Assuming that the planes left at the same time, using different runways, how
far apart (to the nearest km) are the two planes after 90 minutes? N30°W means the angle
between north and west is 30° and 545°W the angle between south and west is 45°.
Please help ASAP!
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:
c= 3/5(n)+2.5
Step-by-step explanation:
Let
c -----> the cost of some taxi journeys
n ----> the number of miles
we know that
The graph is a line
The equation of a line in slope - intercept form is
c=m(n)+b
where
m is the slope
b is the c-intercept (value of c when the value of n is equal to zero)
Observing the graph we have the points
(0,2.5), (5,5.5)
Find the slope
The formula to calculate the slope between two points is equal to
m= c2-c1/n2-n1
substitute the values
m=5.5-2.5/5-0
m=3/5
we have
b=2.5 -----> because the point (0,2.5) is the c-intercept
substitute in the equation of slope-intercept form
c=3/5(n)+2.5

How much will it cost in Canadian dollars to purchase €2000 at a bank that charges a 2.2% commission on the transaction? Use an exchange rate of $1 Canadian equals €0.711142.
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
If you randomly select a letter from the phrase "Do not run on Ichiro," what is the probability that you select a vowel? (Your answer must be in the form of a reduced fraction.)
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

If Andre made another countryard scale drawing at a scale of 1 to 12, would this drawing be smaller or larger than the first drawing ? Explain your reasoning.
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.

Leo wants to paint a mural that covers a wall with an area of 300 square feet. The height of the wall is 13 of its length. What is the length and the height of the wall?
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]
