Answer:

h = 1,268 cm

Step-by-step explanation:

V = (π·r²·h)/3, general formula

83 = (π·4²·h)/3, substitute what is given V= 83 cm³ and r = 4 cm

83 ·3 = (π· 16·h)·3/3, multiply both sides by 3 and solve 4² = 16

249 = π·16·h, multiply 83·3 = 249 and 3/3 = 1

249/ π·16 = h , divide both sides by π·16

1,268.146587 = h, solve

1,268 ≈ h , is rounded to the nearest cm

Solving Rational equations. LCD method. Show work. Image attached.

Ugo [173]

Answer:

$k=\frac{1}{2}$

Step-by-step explanation:

The given rational equation is

$\frac{5k}{k+2}+\frac{2}{k}=5$

The Least Common Denominator is

$k(k+2)$

Multiply each term by the LCD.

$k(k+2)\times \frac{5k}{k+2}+k(k+2)\times \frac{2}{k}=5k(k+2)$

Simplify;

$k\times \frac{5k}{1}+(k+2)\times \frac{2}{1}=5k(k+2)$

$\Rightarrow k(5k)+2(k+2)=5k(k+2)$

Expand;

$\Rightarrow 5k^2+2k+4=5k^2+10k$

Group similar terms;

$\Rightarrow 5k^2-5k^2+2k-10k=-4$

$\Rightarrow -8k=-4$

Divide by -8.

$k=\frac{1}{2}$

The soccer teams in a club league are ordering new jerseys. The cost is $18 per jersey plus $10 shipping per team.

Lelechka [254]

Answer:

10*7+ 18x *7 =2590

or 70 + 18x*7 =2590

Step-by-step explanation:

10*7 to find out how much the shipping costs for the 7 teams altogether

18*x because you need to find how much the jerseys cost for all the soccer teams

then multiply it by 7 to find how many players on each team

when you solve for x you get 20

there are 20 players on each on team.

Thank you to whoever helps!

Answer:

M
90°

Step-by-step explanation:

The segment joining an original point with its rotated image forms a chord of the circle of rotation containing those two points. The center of the circle is the center of rotation.

This means you can find the center of rotation by considering the perpendicular bisectors of the segments joining points with their images. Here, the only proposed center that is anywhere near the perpendicular bisector of DE is point M.

Segment AD is perpendicular to corresponding segment FE, so the angle of rotation is 90°. (We don't know which way (CW or CCW) unless we make an assumption about which is the original figure.)
