Answer:

C:1 and 3/4

Step-by-step explanation:

We can use a ratio to solve

1 day             x days

-------    =    -------------

24 hours       42 hours

Using cross products

1 * 42 = 24x

Divide each side by 24

42/24 = x

21/12 = x

7/4 = x

4/4 + 3/4 =x

Answer:

h'(x) = -10x + 20

Step-by-step explanation:

To get the derivative of [tex]ax^{n}[/tex], simply use the following formula:

[tex]a(n)x^{n-1}[/tex]

We have the function, h(x) = -5x^2 + 20x

Using the formula, we get the derivative to be:

-10x + 20

so h'(x) = -10x + 20

Trigonometric functions

Answers

9514 1404 393

Answer:

  β ≈ 39.9°

  θ ≈ 50.1°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships between the sides of a right triangle and the trig functions of the acute angles.

For angle β, we know the opposite side and the hypotenuse, so the relevant relation is ...

  Sin = Opposite/Hypotenuse

  sin(β) = 61/95

The inverse function is used to find the angle when the sine is known.

  β = arcsin(61/95) ≈ 39.9°

Of course, the angle θ is the complement of this:

  θ = 90° -39.9° = 50.1°

Answer:

Step-by-step explanation:

sin β = 61/95 = 0.642105

β = 39.95 degrees.

O = 90 - 39.95

= 50.05 degrees

cos O = 61/95.

Note that cos (90-β) = sin β.

Answers

answer:

・x = 50

・y = 61

step-by-step explanation:

・first things you should know —

y + 8 + 2x + 11 = 180 ( supplementary angles equal to 180° )

・five sides add up to 540° ( pentagon! )

・therefore:

108 + 125 + 98 + 98 + 2x + 11 = 540

440 + 2x = 540

2x = 100

x = 50

use what you know and plug in ;

y + 8 + 2x + 11 = 180

y + 8 + 2(50) + 11 = 180

y + 119 = 180

・y = 61

you can always plug in or substitute to check your answers.ᐟ

A stadium has 47,000 seats. Seats sell for $42 in Section A, $36 in Section B, and $30 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,779,000 from each sold-out event. How many seats does each section hold?​

Answers

Answer:

section A holds 23,500 Section B holds 11,750 And Section C holds 11,750

Step-by-step explanation:

Section A is half of the stadium so divide 47,00 by 2 you get 23,300 so that is Section A than b and c are the other half for divide 23,500 by 2 and you get 11,750

Answer:

56

Step-by-step explanation:

according to the sum of the exterior angles of  a polygon, we get that the exterior angles of this polygon add up to 360

so our equation is: 9x-31+7x-2+4x+33=360,

the -31-2+33 cancel out,

and combining like terms gives us: 20x=360

so x=18,

from here we know that DCE equals to 180-7x+2, because it is an exterior angle, therefore the angle is 180-126+2, which is 56
