Answer:

sinQ=cosR

Step-by-step explanation:

First we need to find out the measure of ∠R.

The sum of all the angles in a triangle add up to 180. Therefore:

∠Q+∠R+∠S=180

66+∠R+90=180

∠R=180-156

∠R=24°

Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.

sinQ=cosR

sin66=cos24

0.9135454576=0.9135454576

So the second equation is the correct relation.

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

As given in the question, we know that:

The ratio of the area of the circle to the area of the square is π/4

The formula to find the volume of the cone is:

V = 1/3*the height*the base area

<=> V1 = 1/3*h*π $r^{2}$

The formula to find the volume of the pyramid is:

V2 = 1/3*the height*the base area

<=> V = 1/3*h*4 $r^{2}$

=> the ratio of volume of the cone to the pyramid is:

= $\frac{V1}{V2}$

= (1/3*h*π $r^{2}$ ) / ( 1/3*h*4 $r^{2}$ )

= π/4

S we can conclude that the volume of the cone equals π/4 the volume of the pyramid

Hope it will find you well.

7,013 ×10⁷ as a whole number

Charra [1.4K]

Answer:

70130000000

Step-by-step explanation:

(Assuming that that 7013 is supposed to be 7013 not 7.013), We will move the decimal place to the right 7 times, since it is 10 to the power of 7. Since the decimal place is at the end of the number, we have to add 7 zeros. This becomes 70130000000.

7th grade sac practice problems look at the triangular prism below. each triangular face of the prism has a base of 3 centimeter

xxMikexx [17]

Answer:

72cm³

Step-by-step explanation:

Base of the triangular face =3 cm.

Height of the triangular face = 4 cm.

Length of the prism = 12 cm.

Volume of a Prism= Base Area X. length

The base of a triangle prism is a triangle, therefore:

Volume of a Triangular Prism= ½bh X Length

=½ X 3 X 4 X 12

=½ X 144

=72cm³

Volume of the triangular Prism= 72cm³

Ramon and justine are both watching brodcast both star at 7:00 a.M and ends at 9:00 a.M one one shows commercials every 17 minut

hoa [83]

Answer:

<h2>1:58 minutes after the show</h2>

Step-by-step explanation:

Step one:;

given data

start time= 7:00 am

end time= 9:00 am

we are told that one broadcast shows commercial every 17minutes

and the other shows commercials every 14 minutes

now the time when they both sho commercial is given by the greates common multiple of the times 17 and 14

multiples of 17= 17,34,51,68,85,102,119,136,153,170,187,204,221,238

multiples of 14= 14,28,42,56,70,84,98,112,126,140,154,168,182,196,210,224,238

for the number above 238 is common to both

238minutes to hours= 3.96667

=3:58 minutes

this shows that commercials will show at the same time 1:58 minutes after the show
