What is the value of y?


y =

Answer:

A- c=2.25g

Step-by-step explanation:

If you look at this problem, you will see that the only one that makes since is A. B is incorrect because its pounds and you are trying to find the total. C is incorrect because C stands for cost in the problem and we are trying to find the cost. D is the same explanation as C.

Answer:

166,000(1 + 0.085)^t ; $195,000 ; $230,000

Step-by-step explanation:

Given that :

Rate of increase = 8.5% = 0.085 per year

Initial value ; price in 2011 (A) = $166,000

Formula to predict the median price t years after 2011 ;

At a continous rate :

Median price, P:

P = initial price (1 + rate)^t

P = 166,000(1 + 0.085)^t

t = time since 2011 ;

Median price of home in 2013:

t = 2013 - 2011 = 2

P = 166,000(1 + 0.085)^2

P = 166000(1.085)^2

P = 166000(1.177225)

P = 195419.35

P = $195,000 ( nearest $1000)

Median price of home in 2013:

t = 2015 - 2011 = 4

P = 166,000(1 + 0.085)^4

P = 166000(1.085)^4

P = 166000(1.385858700625)

P = 230052.54430375

P = $230,000 ( nearest $1000)

Answer:5 hours

Answer:

328 square inches

PLZ MARK AS BRAINLIEST

Step-by-step explanation:

Lateral Area of Pyramid:

L = 1/2Pl

l = 15.9

P = 2(8.2) + 2(8.2) = 32.8

L = 1/2(32.8)(15.9) = 260.76

Surface Area:

SA = B + L

B = (8.2)(8.2) = 67.24

L = 1/2(32.8)(15.9) = 260.76

SA = 67.24 + 260.76 = 328

Answer:

c. In 2 seconds, the commuter train travels 120 feet.

Step-by-step explanation:

Given

The attached graph

Required

What does x-coordinate of 2 represents

Represent this coordinate with (x,y)

From the graph:

[tex]x = 2[/tex] when [tex]y = 120[/tex]

Note that:

x = time and y = distance

So:

[tex](x,y) = (2,120)[/tex]

Which means:

At 2 seconds, the train has travelled a distance of 120ft

From the list of options, (c) is correct

C) C is correct

Step-by-step explanation:

Answer:

c = 30m + 75

Step-by-step explanation:

Because the 75 dollars is only one time you add that to the total. Because it is 30 dollars PER MONTH and m is the number of months you would multiply those two in order to know how much you would be paying!

Hope this helps!

Step-by-step explanation:

Answer:130 85/288 ok check my explaination if its reasonable

Step-by-step explanation:

ok youre figuring out the volume right? base times height.  5x25 1/12=125 5/12. 125 5/12x 25 inches=260 85/144 /2=130 85/288. you have to divide it by 2 because i figured it out as a rectangle.

Answer:

The answer is 96.

Step-by-step explanation:

5 goes into 48, 9 times. 48 minus 45 is 3, bring down the zero to get 30. 5 goes into 30 6 times. So 30 minus 30 equals zero.

Answer:

m = -8

Step-by-step explanation:

have a nice day! :)

Answer:

From this quation:

4m = -32

We need to get m, so we can divide both sides by 4:

4m / 4 = -32 /4

m =  -8

You can try to replace it to see if it's correct:

4 * 8 = -32

Answer:

30

60

90

120

180

210

240

hope it helped have a good day mate

Answer:

126

Step-by-step explanation:

The supplement of 54° is the angle that when added to 54° forms a straight angle (180° ). So,

54 + x = 180

x = 126

Answer:

0 = 73

add 90 and 17 which equals 107 take 180 - 107 = 73

Answer:

2m + 5s = 15

I hope it helps.

have a great day.

Answer:

252 cm²

Step-by-step explanation:

Basically I just split up the figure into three smaller rectangles and then found the lengths and widths of all of them. Then I found the area of all of them by multiplying the sides and then added up all the three areas together.

Plz let me know if you want a more in depth explanation and I can help more in the comments!

Answer:

2n - 3

Step-by-step explanation:

twice a number means to multiply it by 2

difference of a number and 3 is a number being reduced by 3 so the 3 comes after the subtraction sign

Answer:

y=-3x+8

Step-by-step explanation:

Slope intercept is as follows: y=mx+b

m is the slope so replace the m with -3

y=-3x+b

b is the y intercept, so replace the b with 8 (keep in mind that had the y-intercept been negative, we would have subtracted)

This then gives you

Answer:

martin can make 20 jumbo cookies

Answer:

a)

initial value problem representing the salary is; S(t) = 1.[tex]e^{0.10t}[/tex]  

b)

S(0) = 1

Therefore; S(0)  is 1 million dollar

S(1) = 1.105170918075647

Therefore; S(1)  is 1.105170918075647 million dollar

Step-by-step explanation:

Given that;

Initial salary of football coach = 1 million dollar

raise of 10% every year (so exponential growth model) r = 10% = 0.10

a) initial value problem to represent the salary

lets S represent salary in millions dollars and t represent time in years.

S(t) = S₀[tex]e^{rt}[/tex]

so,

at S₀ = 1 million dollars } { r = 0.10 }

S(t) = 1.[tex]e^{0.10t}[/tex]  

Therefore, initial value problem representing the salary is; S(t) = 1.[tex]e^{0.10t}[/tex]  

b) What is s(0) and s(1)

at s(0)

S(t) = 1.[tex]e^{0.10t}[/tex]  

we substitute

S(0) = 1.[tex]e^{0.10*0}[/tex]

S(0) = 1.[tex]e^{0}[/tex]

S(0) = 1

Therefore; S(0)  is 1 million dollar

at s(1)

S(t) = 1.[tex]e^{0.10t}[/tex]  

we substitute

S(1) = 1.[tex]e^{0.10*1}[/tex]

S(1) = 1.[tex]e^{0.10}[/tex]

S(1) = [tex]e^{0.10}[/tex]

S(1) = 1.105170918075647

Therefore; S(1)  is 1.105170918075647 million dollar

Answer:

3. Tony's deposit earned $40.80 in simple interest over 3 years in an account with an interest rate of 1.7%. How much did Tony deposit?

Answer:

Option (4)

Step-by-step explanation:

Jordan spent 5 hours studying for 3 test with equal amount of time studying for each test.

On the number line, there are 3 small segments between each number.

Every small segment will represent time = [tex]\frac{1}{3}[/tex] hours

Total number of small segments = 15

If Jordan takes 3 equal durations for the study of each test,

Total number of small segments for each test = [tex]\frac{15}{3}=5[/tex]

Now we can plot these points on the number line.

Further count the segments for the answer ( 1 hour plus 2 small segments)

= 1 + [tex]2\times \frac{1}{3}[/tex]

= [tex]1\frac{2}{3}[/tex]

Therefore, time given for studying each test = [tex]1\frac{2}{3}[/tex] hours

Option (4) will be the answer.

Answer:

x = 10 or x = 2

Step-by-step explanation:

Solve for x:

x^2 - 12 x + 20 = 0

Hint: | Solve the quadratic equation by completing the square.

Subtract 20 from both sides:

x^2 - 12 x = -20

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 36 to both sides:

x^2 - 12 x + 36 = 16

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 6)^2 = 16

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 6 = 4 or x - 6 = -4

Hint: | Look at the first equation: Solve for x.

Add 6 to both sides:

x = 10 or x - 6 = -4

Hint: | Look at the second equation: Solve for x.

Add 6 to both sides:

Answer: x = 10 or x = 2
