Hey there!

Let's write this as an equation, with n representing the unknown number.

0.5n-35=14

First, we add 35 to both sides.

0.5n=49

We divide both sides by 0.5.

n=108

Therefore, your number is 108

I hope this helps!

Inessa05 [86]

Answer:

10.846 hours

Step-by-step explanation:

first you add all the calories= 1410 calories

then you divide 1410 calories by 130 (the calories you can burn in one hour)

your answer is 10.846 which means that it takes 10.846 hours to consume 1410 calories.

Hhhhhhhhhhhhhhhhhhhhhh

irga5000 [103]

Answer:

13 miles

Step-by-step explanation:

The shortest distance would be a straight line between the two points. This would be a hypotenuse of a right triangle

We can use the Pythagorean theorem to determine the length

a^2+b^2=c^2

5^2 +12^2 = c^2

25+144= c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 = c

The equation of a parabola is 18(y−5)2=x+3 . What are the coordinates of the focus? (−3, 7) (−5, 5) (−1, 5) (−3, 3)

aleksandrvk [35]

18(y-5)^2=x+3

do the algebra to make it into =x form

x=18y^2-180y+447

then you take the form of the focus, you can do the math

Physics students were modeling the height of a ball once it was dropped from the top of a 10 foot ladder. The

julsineya [31]

Answer:

Interval notation: [0, 2.236]

Set Builder notation: $\{t\ |\ 0\le t\le 2.236\}$

Step-by-step explanation:

Given that:

Equation of height of the ball dropped from a height of 10 foot, as:

$h(t) = 10 - 2t^2$

Where $t$ is the time since the ball was dropped.

To find:

The domain of the function in Interval and set builder notation.

Solution:

Domain of a function is defined as the set of valid input values that can be given to the function for which the function is defined.

Here, input is time.

We can not have negative values for time.

Therefore, starting value for time will be 0 seconds.

And the value of height can not be lesser than that of 0 ft.

$0= 10 - 2t^2\\\Rightarrow 2t^2=10\\\Rightarrow t^2=5\\\Rightarrow t =2.236\ seconds$

Maximum value for time can be 2.236 seconds.

Therefore the domain is:

Interval notation: [0, 2.236]

Set Builder notation: $\{t\ |\ 0\le t\le 2.236\}$
