Answer:

$5.47

Step-by-step explanation:

You multiply 2 by 0.79. Then you add that result (1.58) to 3.89 and you get your answer.

Answer:

68.5 feet per minute

Step-by-step explanation:

rate of descent = feet / minute

First you need to find how many feet it has descended:

beginning altitude- ending altitude = total feet descended

5717 feet - 3388 feet = 2329 feet

To figure out the rate of decent we will divide

2329 feet / 34 minutes = 68.5 feet per minute

The hot air ballon descended 68.5 feet per minute for 34 minutes.

Answer:

x = 7

Step-by-step explanation:

- 3x - (1 - x)= -15

-3x - 1 + x = -15

-2x - 1 = -15

-2x = -14

x = 7

Answer:

This quadratic has two unequal, imaginary roots.

Step-by-step explanation:

y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots.  In this case they happen to be different (unequal), as well as imaginary.

Setting y = 3x^2 + 8 = 0, we get:

3x^2 = -8, or

x^2 = -8/3

Taking the square root of both sides, we get

x = ±i√(8/3) (2 imaginary roots)

Step-by-step explanation:

the three rational numbers equivalent to each of the following rational number:-

i) -2/5=-4/10,-6/15 and -8/20.

ii) 3/7=6/14,9/21_and 13/28

Answer:

She will do 61 sit ups.

Step-by-step explanation:

The number of situps are increasing by 4 each day.

So at this rate...

Day 6: 37

Day 7: 41

Day 8: 45

Day 9: 49

Day 10: 53

Day 11: 57

Day 12: 61

Responder:

4080,96 Julios

Explicación paso a paso:

La energía potencial gravitacional adquirida se puede obtener mediante la relación:

EPG = masa * aceleración por gravedad * altura

Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros

EPG = 52 * 9,81 * 8

EPG = 4080,96 julios

Answer:

7-(-3)

Step-by-step explanation:

The answer is 7-(-3).

You're subtracting (-3) from 7.

7-(-3) = 7+3 because -(-3) = 3.

Answer:

y=3

Step-by-step explanation:

y=3  ZERO slope

Since each point has 3 (same number ) as y coordinate,this is a zero slope

You will see an horizontal line on the coordinate plan

Answer:

Answer:

A. Add -2 to both sides

Step-by-step explanation:

The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

in³

Answer:

Formula for Volume of Cylinder = pi x r^2 x h

Volume = 3.14159 x 7^2 x 3

Volume  = 461.81373 in^3

Volume  = 461.8 in^3

Answer:

[-1/2,1/20]

Step-by-step explanation:

Answer:

[-1/2,1/20]

Step-by-step explanation:

In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.

The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.

We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.

The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

8/14: 4/7, 16/28, 32/56

Answer:

10.

Step-by-step explanation:

Lets define a square root.  A square root is a number multiplied by itself.        10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.

21 would be the correct aswer

Step-by-step explanation:

Answer:

(-3, -4)

Step-by-step explanation:

y= -4

so you plus y in for the y=2x+2 equation where you get x=-3

[tex]\huge\text{Hey there!}[/tex]

[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]

[tex]\large\text{-4 = 2x + 2}[/tex]

[tex]\large\text{TURN the EQUATION}[/tex]

[tex]\large\text{2x + 2 = -4}[/tex]

[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]

[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]

[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]

[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]

[tex]\large\text{2x = -6}[/tex]

[tex]\large\text{DIVIDE by 2 to BOTH SIDES }[/tex]

[tex]\mathsf{\dfrac{2x}{2}=\dfrac{-6}{2}}[/tex]

[tex]\large\text{CANCEL out: }\mathsf{\dfrac{2}{2}}[/tex] [tex]\large\text{because that gives you 1}[/tex]

[tex]\large\text{KEEP: }\mathsf{\dfrac{-6}{2}}[/tex]  [tex]\large\text{because it gives us the value of x }[/tex]

[tex]\boxed{\boxed{\large\text{Answer: \bf x = -3}}}\huge\checkmark\\\\\boxed{(-3,-4)}[/tex]
