Answer:

x = 4.99°

Step-by-step explanation:

Reference angle = x

Opposite side to x = 20 cm

Hypotenuse = 230 cm

Applying trigonometric ratio formula, we would have the following equation:

[tex] sin(x) = \frac{Opp}{Hyp} [/tex]

Plug in the values

[tex] sin(x) = \frac{20}{230} [/tex]

[tex] x = sin^{-1}(\frac{20}{230}) [/tex]

x = 4.99° (approximated to nearest hundredth)

At Smith’s Bike Rentals, it cost $27 to rent a bike for 6 hours. How many dollars does it cost per hour of bike use

Answers

Answer:

$4.50 per hour

Step-by-step explanation:

Step 1: 27 divided by 6 is 4.50

Step 2: Double check your work by multiplying 4.50 times 6 to make sure you get 27

To find how much it would cost for one hour you would need to divide 27 by 6.

27/6 = 4.5

Therefore it costs $4.5 to rent the bike per hour

Answers

Answer:

For figure 1:

Area of rectangle = 7x + 21

For figure 2:

Area of rectangle = [tex]\mathbf{p^2-9p }[/tex]

Step-by-step explanation:

We need to find area of rectangle

The formula used is: [tex]Area\:of\:rectangle=Length\times Width[/tex]

For figure 1:

Length = 7

Width = x+3

Putting values in formula and finding area of rectangle

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times (x+3)\\Now,\: multiply\:7\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=7(x)+7(3)\\Area\:of\:rectangle=7x+21\\[/tex]

So, area of rectangle = 7x + 21

For figure 2:

Length = p

Width = p-9

Putting values in formula and finding area of rectangle

[tex]Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=p\times (p-9)\\Now,\: multiply\:p\:with\:terms\;inside\:the\:bracket\\Area\:of\:rectangle=p(p)-p(9)\\Area\:of\:rectangle=p^2-9p\\[/tex]

So, area of rectangle = [tex]\mathbf{p^2-9p }[/tex]

Nancy buys 2 large pizzas for her brother's birthday party. The girls at the party eat 78 of a large pizza. The boys at the party eat 58 of a large pizza. Nancy says about 112 pizzas were eaten at the party. Is Nancy correct?
Nancy is wrong because 78 is close to the benchmark 12 and 58 is close to the benchmark 12 and 12 + 12 = 1.


Nancy is wrong because 78 is close to the benchmark 1 and 58 is close to the benchmark 0 and 1 + 0 = 1.


Nancy is correct because 78 is close to benchmark 1 and 58 is close to benchmark 12 and 1 + 12= 112. .


Nancy is wrong because 78 is close to benchmark 1 and 58 is close to benchmark 1 and 1 + 1 = 2.

Answer:

2 pt + 1c

Step-by-step explanation:

There are 2 cups in a pint. So, 2c = p, dividing 2 from both sides, we get

c = (1/2)p

Replace c with 1/2 p in the equation

5 pt - (2pt + (1/2)p)

= 5pt - 2pi - (1/2)p

= 3pt  - (1/2)p

= 2pt  + (1/2)p

Replace back (1/2)p for c

2pt  + (1/2)p =

2 pt + 1c

In Randy's town all stand alone store front signs must be exactly 8 feet high. When mounted atop a pole , the combined height of the sign and pole must be less than 20 feet or greater than 35 feet so that they dont interfere with the power and phone lines. Write a compound Inequality to represent the possible above ground height of the pole.

Answers

Answer:

[tex]x<12[/tex] or [tex]x > 27[/tex]

Step-by-step explanation:

Given

[tex]Lower\ Bound = 20[/tex]

[tex]Upper\ Bound = 35[/tex]

[tex]Height = 8[/tex]

Required

Represent as a compound inequality

Let the pole height be x:

So, the combine height of the pole and the sign is [tex]x + 8[/tex]

The height must be less than 20ft.

So, we have:

[tex]x + 8 < 20[/tex]

Subtract 8 from both sides

[tex]x + 8 - 8 < 20 - 8[/tex]

[tex]x < 20 - 8[/tex]

[tex]x<12[/tex]

or The height must be less than35ft

So, we have:

[tex]x + 8 > 35[/tex]

Subtract 8 from both sides

[tex]x + 8 - 8 > 35 - 8[/tex]

[tex]x > 35 - 8[/tex]

[tex]x > 27[/tex]

So, the compound inequality is:

[tex]x<12[/tex] or [tex]x > 27[/tex]

Write the equation of a line that is perpendicular to y=7x−2 and passes through the point (14,8).(1 point) y=7x−90 y=10x−17 y=−17x+1067 y=−17x+10

Answers

Answer:

[tex]\huge\boxed{y=-\frac{1}{7}x+ 10}[/tex]

Step-by-step explanation:

In order to find the equation of this line, we need to note two things.

A) The slope of two lines that are perpendicular will be opposite reciprocals (that is, multiplying them gets us -1.)B) We can substitute a point inside an incomplete equation to try and find a missing value.

So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.

Reciprocal of 7:    [tex]\frac{1}{7}[/tex] Opposite of [tex]\frac{1}{7}[/tex]:    [tex]-\frac{1}{7}[/tex]

So the slope of this line will be [tex]-\frac{1}{7}[/tex]. The y-intercept will change, and we can substitute what we know into the equation [tex]y=mx+b[/tex].

[tex]y = -\frac{1}{7}x+b[/tex]

Now, we can substitute a point on the graph (14, 8) into this equation to find b.

[tex]8 = -\frac{1}{7} \cdot 14 + b[/tex] [tex]8 = -\frac{14}{7} + b[/tex] [tex]8 = -2 + b[/tex] [tex]b = 10[/tex]

Now that we know the y-intercept, we can finish off our equation by plugging that in.

[tex]y = -\frac{1}{7}x + 10[/tex]
