16 × 0.25 = 4
16 - 4 = 12
So therefore, 3-6 year old aneed 12 hours of sleep.

Or you could solve it this way:
100 - 0.25 = 0.75
16 × 0.75 = 12

Either of the two ways you would get 12

Choosy Chocolates sold chewy squares and chocolate stars at a ratio of 3 to 8. 45 more chocolate stars were sold than chewy squa
masya89 [10]
So 45 more chocolate stars were sold compared to chewy squares, which makes it a ratio of 3:8, hence we can assume that (45÷5=9) is the amount sold for each ratio.

If you multiply 9 by (3+8=11), you will get 99.

What is the growth factor associated with the following growth rate: 30% decrease
fenix001 [56]

Given:

Growth rate = 30% decrease

To find:

The growth factor associated with the given growth rate.

Solution:

The general exponential function is:

y=a(1+r)^x

y=a(b)^x

Where, a is the initial value, r is the growth rate in decimal and b=1+r is the growth factor.

It is given that the growth rate is 30% decrease. So,

r=-30\%

r=-\dfrac{30}{100}

r=-0.3

Now,

b=1+r

b=1+(-0.3)

b=1-0.3

b=0.7

Therefore, the growth factor is 0.7.

5 1/4 - 2 2/3, how do I solve please?
densk [106]
5 1/4 - 2 2/3

first you find the LCM, so u can make both fractions have a like denominator. I'm thinking the LCM is 12, so:

(5 3/12) - (2 8/12) 
= 63/12 - 32/12
=31/12
= 2 and 7/12

5 1/4 - 2 2/3 = 2 7/12

Which function describes this graph?<br><br> f(x)=4x+2<br> f(x)=x+2<br> f(x)=1/4x+2
GaryK [48]
F(x) = 1/4x + 2

This means that the y-intercept is 2 and the slope is 1/4.

Hope this helps!
