Answer:
x = 30°
Step-by-step explanation:
The tangent and secant from a point outside the circle combined with the radius form a triangle.
The sum of the 3 angles in the triangle = 180°
The angle at the centre of the circle = 60° ( equilateral triangle )
The angle between the tangent and the radius on the circle = 90°, thus
x = 180° - (90 + 60)° = 180° - 150° = 30°

The grams of protein needed daily is 50 grams.
Let the grams of protein needed daily be represented by x.
Since one serving of granola provides 4% of the protein, this will be:
= 4% × x
= 4/100 × x
= 0.04 × x
= 0.04x
Based on the information given, the grams is protein needed daily will be:
x = 0.04x + 48
Collect like terms
x - 0.04x = 48
0.96x = 48
x = 48/0.96
x = 50
Therefore, the grams of protein needed daily is 50 grams.
Read related link on:
Remember (4%=4/100=0.04).
x=4% of x + 48 g
therefore, we can suggest this equation:
x=0.04x+ 48
x-0.04x=48
0.96x=48
x=48/0.96
x=50
Answer: 50 grams of proteins you need daily.
Other method:
the remaning is equal to =100%-4%=96%
Therefore: 96% of x=48
Remember (96%=96/100=0.96)
we can suggest this equation too.
0.96x=48
x=48/0.96
x=50
Answer:50 grams of proteins you need daily.
How much more plaster did Zuri use for the larger sphere?
Use 3.14 to approximate pi and express your answer in hundredths.
Answers
volume of a sphere is 4/3 times pi times radius^3
so first calculate the smaler sphere
radius=6
pi is aprox 3.14
4/3 times 3.14 times r^3
4/3 times 3.14 times 6^3
4/3 times 3.14 times 216
904.32 cm^3=volume
volume of larger
radius=24
4/3 times 3.14 times 24^3
4/3 times 3.14 times 13824
57876.48 cm^3
so then subtract the volume of the smaller sphere from the larger sphere
57876.48-904.32=56972.16 cm
he used
56972.16 cm^3 plaster
I think you mean to the hundreth's place which is the place denoted by the x in 0.0x so it is to the hundreth's place
he used
56972.16 cm^3 plaster

Here you can only divide by 2 and you get 1/5. That's the simplest form, if you kept dividing you'd get decimals, but the simplest form must be integers.

if total surface area is the area of the sides added up
since 1 side=12 cm^2
then 6 sides=12 times 6 cm^2=72 cm^2
the total surface area=72 cm^2
the surface area of the cube is 72 cm ².
