In ARST, r = 1.7 inches, s = 7.3 inches and ZT=15°. Find the length of t, to the nearest

garri49 [273]

Answer:

The answer is "5.7"

Step-by-step explanation:

Using the cosine rule.

$\cos T = \frac{r^2+s^2-t^2}{2rs} \\\\t^2= r^2+s^2-2rs \cos T ........(i)\\\\r=1.7\\s=7.3\\T=15\\\\t^2= (1.7)^2+(7.3)^2-2(1.7)(7.3) \cos 15^{\circ} \\\\$

$=2.89+53.29-24.82(0.9659)\\\\=32.2064$

$t= 5.6751 =5.7$

Answer:

157.08

Step-by-step explanation:

Hello There!

The first step in solving this problem is to find the formula for volume of a cylinder

To find the volume of a cylinder we use this formula

$V=\pi r^2h$

Where r = radius and h = hypotenuse

we are given the height and the diameter

To convert the diameter to radius we divide the diameter by 2

5/2=2.5

so the radius is 2.5

now we plug in the values

$V=\pi 2.5^28\\2.5^2=6.25\\6.25\pi =19.63495408\\19.63495408*8=157.0796327$

So the volume of the cylinder is 157.0796327

now we just round to the nearest hundredth and get that the volume of the cylinder is 157.08

It takes Mia 1/4 hour to pick out all beads and 1/10 hour to string them. If she only has 5 and 1/4 to make bracelets how many w

JulsSmile [24]

Answer:

Step-by-step explanation:

Mia take 1/4 and 1/10 hours to create a bracelet. This is 1/4 + 1/10 = 10/40 + 4/40 = 14/40 = 7/20.

It takes her a total of 7/20 hours to make the bracelet. She has 5 1/4 hours to work. To find the number of bracelets she can make divide 5 1/4 by 7/20.

Write first 5 1/4 as a mixed number. 21/4. Then rewrite it as multiplication with the reciprocal of 7/20 to divide fractions.

21/4 * 20/7 = 420/28 = 15

She will make 15 bracelets.
