During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her
descent at a rate of 23 feet per minute. Enter an inequality you could solve to find the number of minutes
she can continue to descend if she does not want to reach a point more than 97 feet below the ocean
surface. Use t to represent the variable for the minutes Lainey can continue to descend.
The inequality is
t (select)

Answers

t (23) ≤ 97 - 23

The minus 23 at the back represents the feet she already descended before what the question wants us to calculate

≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)

15 divided by 112.5=75
112.5 divided by 15=7.5
112.5 divided by 15=75

Answers

Answer:

112.5 divided by 15=7.5

112.5 divided by 15=7.5 equation is true answer.

Given option are:

15 divided by 112.5 = 7.5

15 ÷ 112.5 = 0.1333

This option is wrong.

15 divided by 112.5 = 75

15 ÷ 112.5 = 0.1333

This option is wrong.

112.5 divided by 15 = 7.5

112.5 ÷  15 = 7.5.

This option is right.

112.5 divided by 15 = 75.

112.5 ÷  15 = 7.5.

This option is wrong.

Therefore, the correct equation is 112.5 divided by 15=7.5

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4

Answers

Answer:

y-7=4x(x+3)

Step-by-step explanation:

(The 4x is 4 times ...)

Answer:

[tex]y -7 = 4(x+3)[/tex]

Step-by-step explanation:

Point-slope form is in the format of [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a line's slope and a point it passes through, you can write an equation in that format. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted for with real values.

The [tex]m[/tex] represents the slope, thus substitute 4 for [tex]m[/tex]. [tex]x_1[/tex] represents the x-value of one point the line passes through, while [tex]y_1[/tex] represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following answer and equation:

[tex]y-(7) = 4(x-(-3))\\y -7 = 4(x+3)[/tex]

2x
x + 5
All the measurements are in centimetres.
The area of the trapezium is 351 cm2.
(a) Show that 2x2 + x - 351 = 0

Answers

Answer:

Step-by-step explanation:

The area of a trapezium is given as;

Area = [tex]\frac{1}{2}[/tex](a + b)h

where: a is the length of the upper side, b is the length of its base and h is its height.

This implies that; a = x - 4, b = x + 5, h = 2x and area = 351

Thus,

351 =  [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x

      = (x - 4 + x + 5) x

531 = (2x + 1) x

      = 2[tex]x^{2}[/tex] + x

So that;

2[tex]x^{2}[/tex] + x - 531 = 0

This gives a quadratic equation.

Function c is defined by the equation c(n)=50+4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. What is the inverse function.

Answers

Answer:

(x - 50 / 4) = y

Step-by-step explanation:

On photo

To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).

The inverse function would be:

[tex]n = \dfrac{c-50}{4}[/tex]

Given that:c(n) = 50 + 4nc is monthly cost in dollars, of visiting a gym.n is the number of visits.To find:

Inverse function of given function.

What is inverse function and when is it possible to find such function?

The inverse function of f is a function of f which can remove the effect of f on its input.

Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)

Since the given function is a linear function and not a  vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.

Finding the inverse function of c(n) = 50 + 4n:

[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]

Thus, we have the inverse function of given function as:

[tex]n = \dfrac{c-50}{4}[/tex]

Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5 pound bags can Roberta fill? Does she have any left over?​

Answers

Answer:

2 pound bags and have a remeinder of 1/10

Step-by-step explanation:

Answer:

She can fill 2 bags for her lunch and will have 1/10 pound left.

Step-by-step explanation:

It is easier if there is a common denominator, so I made the 2/5 into 4/10, so it is the same as 9/10 pound she bought.

4/10 is one bag, and if you double that, it is 8/10 pounds used. This is two bags of raisins for her lunch.

9/10 - 8/10 leaves 1/10 pound remaining, and not in a bag.
