Answer:
39
Step-by-step explanation:
you need to work backwards
86-2-6=78
therefore, 78 = 2y
y = 2y/2, so 78/2 = 39
Answer:
The value 39 will make the equation true
Step-by-step explanation:
Y + 2 + 6 + Y = 86
Y + Y + 2 + 6 = 86
2Y + 8 = 86
2Y = 86 - 8
2Y = 78
Y = 78 ÷ 2
Y = 39
Thus, The value 39 will make the equation true
FOR VERIFICATION ONLY:-Y + 2 + 6 + Y = 86
39 + 2 + 6 + 39 = 86
86 = 86
Hence, L.H.S = R.H.S

Adrian took out a simple interest loan for $2000. The rate on this loan is 7% and he will pay it back in 5 years. How much money will Adrian owe at the end of 5 years including interest?
Answer:
i think its 700
Step-by-step explanation:
7%of 2000 is 140 and 140 x 5 is 700
Answer: $700 interest
Note that the formula for simple interest is I=Prt
1. Identify the Principal amount (P), rate (r), and time (t)
Principal amount=$2,000
Rate: 7% (0.07)
Time: 5 years
2. Plug the numbers into the formula; always make sure that the rate is in decimal form and the time is in years.
2,000*0.07*5=700
3. Final answer: $700
there is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 that are different in colour?
Answer:
60/121
Step-by-step explanation:
There are two outcomes that are included in the event "2 different in color" -- either Red followed by Blue (RB) or Blue followed by Red (BR).
Probability of RB is [tex]\frac{5}{11}\times \frac{6}{11}=\frac{30}{121}[/tex] The denominator 11 does not change in the second fraction because you put the first marble back; still 11 marbles in the bag.
Probability of BR is [tex]\frac{6}{11} \times \frac{5}{11}=\frac{30}{121}[/tex]
Probability of RB or BR: add the probabilities to get 60/121.

Step-by-step explanation:
Answer: don’t know the “following probabilities but I have included answers below
Step-by-step explanation:
4 blue + 6 green = 10 total
probability of getting green once and blue next: 6/10*4/9 = 24/90 or about 0.27
probability of green both times: 6/10*6/9 = 36/90 or 0.4
probability of blue first then green next: 4/10*6/9 = same as first answer (about 0.27)
probability of blue both times: 4/10*4/9 = 16/90 or about 0.18
What is the diameter of a hemisphere with a volume of 5403 ft", to the nearest tenth
of a foot?
The diameter of the hemisphere with the given volume is approximately: 27.4 ft.
What is the Volume of a Hemisphere?Volume of hemisphere = 2/3πr³.
Volume of the hemisphere = 5403 ft³
2/3πr³ = 5403
Find r (radius of the hemisphere):
2πr³ = (5403)(3)
2πr³ = 16,209
r³ = 16,209/2π
r³ = 2,579.7
r = ∛2,579.7
r = 13.7 ft.
Diameter = 2r = 2(13.7)

Sabrina borrowed $350000 with a 0.5% interest rate from Bank of America to buy a new condo in orange beach how did it take Sabrina to pay if the loan if she ended up pay &26250 interest plz help me
Answer:
t = 2466.67 years (about 2466 years 8 months)
Step-by-step explanation:
Given: Total P+I (A) = $350000, Principal (P) = $26250, Rate (R) = 0.5%
To find: How long did it take Sabrina to pay if the loan if she ended up pay $26250 interest?
Formula: [tex]t = (1/r)(A/P - 1)[/tex]
Solution: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate
First, converting R percent to r a decimal
r = R/100 = [tex]\frac{0.5 percent}{100}[/tex] = 0.005 per year,
then, solving our equation
t = (1/0.005)((350000/26250) - 1) = 2466.67
t = 2466.67 years
Therefore, it will take Sabrina 2466.67 years (about 2466 years 8 months) to pay off the loan.

Answer:
500 pennies
Step-by-step explanation:
Given that
Carmen saved 592 pennies.
Her sister saved 128 pennies.
Together, they put 250 pennies in wrappers and took them to the bank
We need to find out the total number of pennies Carmen and her sister have left
So,
= 592 pennies + 128 pennies - 250 pennies
= 470 pennies
= 500 pennies

Help would be appreciated for this question!!!
Answer:
A
Step-by-step explanation:
Recall that sin = opposite over hypotenuse
For ∠A we are already given its opposite side length ( 2 ) however the hypotenuse has not been identified.
The triangle shown is a right triangle ( indicated by the little square on the bottom left ) which means that we can find a missing side length, more specifically the hypotenuse, using the Pythagorean theorem
[tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse
we are given that the legs = 2 and 4 and need to find the hypotenuse
That being said we plug in what we are given and solve for c
[tex]2^2+4^2=c^2\\2^2=4\\4^2=16\\16+4=20\\20=c^2[/tex]
In order to get the exact value of c we must get rid of the exponent.
To do so we can take the square root of both sides
[tex]\sqrt{20} =\sqrt{20} \\\sqrt{c^2} =c\\c=\sqrt{20}[/tex]
hence, the hypotenuse = √20
Now lets look back at the question
Find sin∠A to the nearest hundredth.
well remember sin = opposite over hypotenuse
The opposite of sin∠A is 2 and the hypotenuse is √20
Hence, sin∠A = [tex]\frac{2}{\sqrt{20} }[/tex] which is equivalent to .447213595
Our last step is to round to the nearest hundredth
We get the sin∠A = .45

Three trains - one eastbound, one westbound, and one northbound - leave a city at the same time.
The speed of the northbound train is 20 miles per hour greater than the speed of the eastbound train.
After 9 hours, the distance between the westbound train and the eastbound train is 990 miles.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but let me solve a similar question:
Three trains one eastbound, one westbound, and one northbound leave a city at the same time. The speed of the northbound train is 20 miles per hour greater than the speed of the eastbound train. After 6 hours, the distance between the westbound train and the eastbound train is 420 miles. Twice the speed of the westbound train is 30 miles per hour more than the speed of the northbound train. Find the speeds of the three trains.
Solution:
Speed is the time rate of change of distance. It is the ratio of distance to time taken. Speed is given by:
Speed = distance / time
Let x represent the speed of the eastbound train, y that of the westbound train and z that of the northbound train. Hence:
z = x + 20
x - z = -20 (1)
After 6 hours, the distance between the westbound train and the eastbound train is 420 miles. Hence:
6 hours * x + (6 hours * y) = 420
6x + 6y = 420
x + y = 70 (2)
Lastly:
2y = z + 30
2y - z = 30 (3)
Solving equations (1), (2) and (3) simultaneously gives:
x = 30 miles per hour, y = 40 miles per hour, z = 50 miles per hour.
Hence the speed of the eastbound train is 30 miles per hour, speed of the westbound train is 40 miles per hour and the speed of the northbound train is 50 miles per hour.
A board of length 16 ¾ inches is cut into 4 equal pieces. If 7/8 of an inch is then removed from one of these pieces, what is the length of that piece?
Answer: [tex]\dfrac{53}{16}\ \text{or}\ 3\dfrac{5}{16}[/tex]
Step-by-step explanation:
Given
Length of board is [tex]16\ \frac{3}{4}[/tex]
It is divided into 4 equal pieces i.e. length of each piece is
[tex]\Rightarrow \dfrac{\frac{64+3}{4}}{4}=\dfrac{67}{16}\ \text{in.}[/tex]
If [tex]\frac{7}{8}[/tex] of an inch is removed from one of the pieces then,
[tex]\Rightarrow \dfrac{67}{16}-\dfrac{7}{8}\\\\\Rightarrow \dfrac{67}{16}-\dfrac{14}{16}=\dfrac{53}{16}\ \text{inch}[/tex]
