please help me out thanks ​

Answer:

My uncle is 78 years old.

Step-by-step explanation:

Let the age of your uncle be x.

400 - 2x = 244

Shift (-2x) to the other side and change it to (+2x).

400 = 244 + 2x

Shift (+244) to the other side and change it to (-244).

400 - 244 = 2x

Evaluate.

2x = 156

Find x.

x = 156 ÷ 2

x = 78

Answer:

x³ - 3 x² - 13 x + 15 = 0

Step-by-step explanation:

Basically you can create three factors like this:

(x+3)(x-1)(x-5)=0

That will each represent one zero.

Work it out and you get x³ - 3 x² - 13 x + 15 = 0

Step-by-step explanation:

Useful Log Rules:

=========================================================

Part (a)

All logs shown below are base 3.

log(500) = log(5*100)

log(500) = log(5*10^2)

log(500) = log(5)+log(10^2) .... use log rule 1

log(500) = log(5) + 2*log(10) .... use log rule 3

log(500) = 1.4650 + 2*2.096 ....... substitution

log(500) = 5.657

=========================================================

Part (b)

All logs shown below are base 3.

log(2) = log(10/5)

log(2) = log(10) - log(5) .... use log rule 2

log(2) = 2.096 - 1.4650  ....... substitution

log(2) = 0.631

Answer:

0.11 centimeters/minute

Answer:

m<5 = 133°

m<8 = 47°

Step-by-step explanation:

if <2 = 47°, and <5 is supplementary to <2, that means that together they both have to equal 180°. So, to get the measure of <5, you need to do 180 - 47 to get <5 = 133°.

Now, <5 (133°) is supplementary to <8, so they both have to equal 180° together. So, you must do 180 - 133 to get <8 = 47°. Or, another way to get <8 is to notice that <2 and <8 are alternate interior angles, which means they equal the same amount. So if <2 = 47°, then so does <8.

Answer:

The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.

The Area of a circle is

πr2=808.64

(3.14)r2=808.64

Divide both sides by 3.14

r2=257.5286624

Answer:

23/50

Step-by-step explanation:

46% is the same as 46/100 that can be simplified to 23/50

The percentage 46% as a fraction in its simplest form is 23/50.

The given fraction is 46%.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The percentage can be written in fraction by dividing the number by 100.

Here, 46% = 46/100

= 23/50

Therefore, the percentage 46% as a fraction in its simplest form is 23/50.

Answer:

3.64 for 13 candy bars

Step-by-step explanation:

Answer:

Aman's age = 20, Arun's age = 28

Step-by-step explanation:

Let [tex]x[/tex] = Aman's age

Let [tex]y[/tex] = Arun's age

- - - -

[tex]x+4+y+4=56[/tex] (Sum of their age is 56 after 4 years in the future)

[tex]x+y+8=56[/tex]

[tex]x+y=48[/tex]

[tex]\frac{x}{y} = \frac{5}{7}[/tex] (Ages are in the ratio 5:7)

[tex]x=\frac{5}{7}y[/tex]

Now, we can use substitution to find for Arun's age:

[tex]x+y=48[/tex]

[tex]\frac{5}{7}y+y=48[/tex]

[tex]\frac{12}{7}y=48[/tex]

[tex]y=28[/tex]

∴ Arun is [tex]28[/tex]

To find for Aman's age, we can use substitution:

[tex]x+y=48[/tex]

[tex]x+28=48[/tex]

[tex]x=20[/tex]

∴ Aman is 20

Answer:

21.5 Miles or 21 ½ Miles

Step-by-step explanation:

Plug in 7 as m to 3m + ½.

Then, I get 3(7) + ½.

That concludes to 21 + ½

Add the ".5" or "½" at the end

So, answer is you get is 21.5 of 21 ½

Answer:

40 miles because they are da same size

Step-by-step explanation:

The perimeter of lot C is 46.64 miles

Lot C is a square, hence the perimeter of lot C with a length of each side as a miles is:

Perimeter = 4 * length = 4a

40 = 4a

a = 10 miles

Lot B is a square, hence the perimeter of lot B with a length of each side as b miles is:

Perimeter = 4 * length = 4b

24 = 4b

b = 6 miles

Let c represent the length of lot A,, since a, b, c form a right angle triangle. Using Pythagoras theorem:

c² = a² + b²

c² = 10² + 6²

c² = 136

c = 11.66 miles

Perimeter of lot C = 4 * c = 4 * 11.66 = 46.64 miles

The perimeter of lot C is 46.64 miles
