Brian spends 1/3 on his wages on rent and 1/4 on food. If he makes £576 per week, how much money does he have left
natta225 [31]

Answer:

Step-by-step explanation:

Money spent on rent =1/3 of $576= 1/3×576= $192

Money spent on food = 1/4 of 576 = 1/4×576 =$144

Money left = 576-(192+144)=

=576-336= $240

A firework rocket consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The d
Svet_ta [14]

Answer:

188π in^2

Step-by-step explanation:

Surface area of the rocket = surface area of the cone + surface area of the cylinder

Surface area of a cone = πr(r+h^2+r^2)

r = 8/2 = 4 in

4π( 4 + 3^2 + 4^2) =

4π ( 4 + 9 + 16) = 116π in^2

Surface area of a cylinder = 2πrh+2πr^2

(2 x n x 4 x 5) + (2 x n x 16)= 72π in^2

116 + 72 = 188π in^2

In △ABC, m∠A=16°, m∠B=49°, and a=4. Find c to the nearest tenth.
xenn [34]

Answer:

= 8.33 inches

Step-by-step Explanation

First add 49 + 16, which equals 65, and subtract that result from 180, since a triangle equals 180 degrees and you find out angle C is equal to 115 degrees.

Now using the formula sinA/a = sinB/b = sinC/c, plug in values and you'd get the equation sin49 x 10/sin115. After solving the equation you'd get about  8.32729886047258 inches.

= 8.33
