Answers

Answer:

x = 35.1 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos x = 27/33

Take the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1(27/33)

x =35.09680123

To the nearest tenth

x = 35.1 degrees

Answer:

x=35.1

Step-by-step explanation:

cos(x)=[tex]\frac{27^{2}+33^{2}-360 }{2(27)(33)}[/tex]

x=35.1(correct to the nearest tenth)

Find the Measure of angle O
(see image)
Only real answers, please

Answers

Answer:

From the given figure we can see that :---

MN||PO, MN=PO and MP=NO

Therefore, angle M=angle N (adjacent sides of the trapezoid)

[tex](8x - 16) = (6x + 20) \\ 2x = 36 \\ \boxed{x = 18}[/tex]

angle M=angle N= (6×18)+20=108+20 =128°

angle O =(180°-128°)=52°

Hence, angle O is 52°.

Paul buys 5 bags of chips and 9 bags of pretzels for $16.95. Ian buys 1 bag of chips and 1 bag of pretzels for $2.55. Find the cost of one bag of chips and one bag of pretzels.

Answers

Answer: The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Step-by-step explanation:

Let x= Cost of one bag of chips

y= Cost of one bag of pretzels.

As per given, we have

5x+9y=16.95        ...(i)

x+y=2.55            ...(ii)

Multiply 5 to (ii), we get

5x+5y=12.75     ...(iii)

Eliminate (iii) from (i), we get

[tex]4y=4.2\\\\\Rightarrow\ y=1.05[/tex]

Put value of y in (ii), we get

[tex]x+1.05=2.55\\\\\Rightarrow\ x=2.55-1.05=1.5[/tex]

Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?


A.

5 miles


B.

158 miles


C.

300 miles


D.

453 miles

Answers

Answer: D. 453 miles .

Step-by-step explanation:

Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.

At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour     [1 hour = 60 minutes],

Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]

[tex]=458-5=453\ miles[/tex]

Jessica is 453 miles from her home after 5 minutes she began returning home.

Hence, the correct option is D. 453 miles .
