Answer: 3 : 1

Step-by-step explanation:

We know that the ratio of A to B is given by :-

\dfrac{A}{B} or A : B .

Given : Number of students having brown hair = 15

Number of students having black hair = 5

Then , the ratio of students with brown hair to students with black hair will be  :-

=\dfrac{\text{No. of students with brown hair}}{\text{No. of students with black hair}}\\\\=\dfrac{15}{5}=\dfrac{3}{1}

Hence, the ratio of students with brown hair to students with black hair = 3 : 1.

Calculate the area of the shaded sector in the circle​
scZoUnD [109]

Answer:

area ≈ 6.3 units²

Step-by-step explanation:

Calculate the area (A ) of the sector as

A = area of circle × fraction of circle

   = πr² × \frac{45}{360}

   = π × 4² × \frac{1}{8}

    = 16π × \frac{1}{8} ← cancel 8 and 16 by 8, leaving

A = 2π ≈ 6.3 units² ( to 1 dec. place )

I need help on how to solve this equation C+(4-3c)-2=0 stp by step
Mumz [18]
Step 1-  Simplify brackets 
c + 4 - 3c -2 = 0
Step 2- Simplify c + 4 - 3c -2 to -2c + 4 - 2
-2c + 4 - 2 = 0
Step 3- Simplify -2c + 4 - 2 to 2c + 2
-2c + 2 = 0
Step 4- Subtract 2 from both sides 
-2c = -2
Step 5- Divide both sides by -2
Answer: c = 1

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb
olga2289 [7]

Answer:

3x = 50 - 10y

Step-by-step explanation:

Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,

So, total weight of 3 lb weights = 3x

And, the weight of 10 lb weights = 10y

Total weight of all his weights = 3x + 10y

According to the question,

Total weight = 50 lb,

⇒ 3x + 10y = 50

Or 3x = 50 - 10y

Which is the required equation.

Second option is correct.
