One third of a number is four more than one fifth of the number. Find the number.

Answer:

1 1/4 hours

Step-by-step explanation:

1.Tom slept the most on the night he slept 8 2/4 hours.

2.Tom slept the least on the night he slept 7 1/4 hours

3.To determine the difference between the night he slept the most and the night he slept the least, we subtract the two values.

4.The difference between the night Tom slept the most and the night Tom slept the least is 1 1/4

So your answer is  1 1/4 hours! :)

Answer:

4

8/2 = 4

Answer:

[tex]\Huge\boxed{C.68}[/tex]

Step-by-step explanation:

Hello There!

The exterior angle of a triangle rule is that the exterior angle  is equal to the sum of the interior opposite angles

So essentially what I'm saying is that

z = 29 + 39

29+39=68 therefore the measure of angle z is 68

Given:

The expression is:

[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]

To find:

The value of the given expression when [tex]x=64[/tex] and [tex]y=27[/tex].

Solution:

We have,

[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]

Putting [tex]x=64[/tex] and [tex]y=27[/tex], we get

[tex]=((64)^2(27)-3)^0+(64)^{\frac{1}{3}}-(4(64))^{\frac{1}{2}}[/tex]

It can be written as

[tex]=((64)^2(27)-3)^0+(4^3)^{\frac{1}{3}}-(4)^{\frac{1}{2}}(64)^{\frac{1}{2}}[/tex]

[tex]=1+4-2(8)[/tex]           [tex][\because a^0=1,a\neq 0][/tex]

[tex]=5-16[/tex]

[tex]=-11[/tex]

Therefore, the value of the given expression [tex]-11[/tex] when [tex]x=64[/tex] and [tex]y=27[/tex].

Answer:

Approximately $14,760 to the nearest 10 dollars.

Step-by-step explanation:

After each year passes the car is worth 100-10 = 90% of the previous year.

So the equation is

A = 25000(0.90)^t     where A is the value of the car and t = the time in years.

So in 5 years:

A = 25000(0.90)^5

= 14762.25

Answer:

Step-by-step explanation:

Here is the complete question

Samantha invested $660 into an account that paid 3.5% interest compounded annually. Samantha did not make any additional deposits or withdrawals

What is the total amount of interest paid by this investment at the end of five years?

A- $115.50

B-$783.87

C-$123.87

$2,755.50

Interst = future value - amount invested

amount invested = $660

Future value = A( 1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years  

$660 x ( 1.035)^5 = $783.87

Interest = $783.87 - $660 = $123.87

Answer:

The first one; -1.2<6.9

Step-by-step explanation:

Answer:

No, it is not the same.

Step-by-step explanation:

1/4 * 8y = 2y

1/4 * -12 = -3

2y - 3 is not the same as 2y - 12

Answer:

No, because once you factor the 1/4 on the first equation you will get -3, not -12 making them not equalivent.

Step-by-step explanation:

x=2.5

Step-by-step explanation:

x+3.5/4=2(2x+2)/4

x+3.5=2x+2/2

x-2x+3.5=1

-x=(-3.5)+1

-x=(-2.5)

-x/(-1)=(-2.5)/(-1)

x=2.5

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

By applying Pythagoras theorem in triangle ABC,

(Hypotenuse)²= (Leg 1)² + (Leg 2)²

AC² = AB² + BC²

AC² = (40 - 15)² + (80 - 75)²

AC² = (25)² + 5²

AC² = 650

AC = √650

AC = 25.495 ft

Since, area of a rectangle = Length × Width

Therefore, area of the garden = 25.495 × 6

                                                  = 152.97

                                                  ≈ 153 ft²

Since, 150 is very close to 153, approximate area of the rectangular garden is 150 ft².

Option D is the answer.

Answer:

  B. 10

Step-by-step explanation:

If this is a list of statements in a programming language that is processed sequentially, y is assigned the value 9+1 = 10. There is no further assignment to y, even after the value of x is changed. So, the final value of y is 10.

__

Additional comment

Some programming languages do their processing in parallel, so that the definition of y would be updated when the value of x gets updated. In that case, the value of y would be changed to 5+1 = 6. Since this is not a choice, the problem is apparently supposed to be interpreted as above.

Answer:

115.5 in²

Step-by-step explanation:

7 x 7 = 49

49/2 = 24.5

(20-7) x 7 = 13 x 7 = 91

24.5 + 91 = 115.5

Answer: 0.04

Step-by-step explanation:

The measurement error is calculated as:

= Error / Ideal value

= (2.5 - 2.4) / 2.5

= 0.1/2.5

= 0.04

Therefore, the correct option is D.

Answer:306 = 80-q is the answer

Answer:

Step-by-step explanation:

3n = 3² × 8                     3² = 3 × 3

n × 3 = 3 × 3 × 8            notice a times 3 on both sides of the equation

                                      divide both sides by 3

n =  3 × 8      

n = 24    <---------------- FINAL ANSWER
