We subtract 28 - 16 and get the number of girls 
so lets do that 
28 - 16 = 12 
now we know the unsimplified ratio os 12 to 16 
simplifed girls 12 ÷ 4 = 3 
simplified boys 16 ÷ 4 = 4 
since it says (girls to boys) we put girls first then boys
so it would become 3 : 4 
Or the answer is B.) 3 : 4

Stella [2.4K]
She worked for five hours on Saturday.

Step by step: 3 hours × $6.50= $19.50

then take the amount of money she made in total and subtract what she made on Friday to find how much she made on Saturday

$52 - $19.50= $32.50

Now take how much she made on Saturday and divide that by $6.50 to find how many hours she worked on Saturday

$32.50 ÷ $6.50= 5 hours

Answer:

The profit is $24

Step-by-step explanation:

Step one:

given the expression for the profit made as

1.25p-0.75p,

we are told that p is the number of pens, hence for p= 48 by substituting into the expression we can find the profit as

Step two:

Profit= 1.25p-0.75p,

Profit= 1.25(48)-0.75(48),

Answer:

a = 4, b = - \frac{3}{2}

Step-by-step explanation:

Given

\frac{8-3\sqrt{2} }{2} = a + b\sqrt{2} ( multiply both sides by 2 to clear the fraction )

8 - 3\sqrt{2} = 2a + 2b\sqrt{2}

For the 2 sides to be equal , then

2a = 8 ( divide both sides by 2 )

a = 4

and

2b = - 3 ( divide both sides by - 2 )

b = - \frac{3}{2}
