Answer:

C, D, F

Step-by-step explanation:

A: 4^2=8 16=8 False

B: 4^2+16=0 16+16=- 32=0 False

C: 2(4)^2=32 - 2*8=16 True 4 squared would equal 16 as well

D: -3(4)^2=-48 -3*16=-48 True Same reasoning as C for -4

E: 6(4)^2 +56=-40 96+56=-40 False

F: 27- 5(4)^2=-53 27-5*16=-53 - 27-80=-53 -53=-53 True 4 Same reasoning as C for -4

Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same rec

Kisachek [45]

Answer:

$2.5h = 3g$

Step-by-step explanation:

Given

$Sugar = 2\frac{1}{2}\ cups$

$Bars = 3\ pans$

Required

Determine the equation for h pans and g cups

We have that:

$Sugar = g$

$Bars = h$

To do this, we make use of the following equivalent ratios.

$Bars : Sugar = Bars : Sugar$

So, we have:

$3 : 2\frac{1}{2} = h : g$

Express fraction as decimal

$3 : 2.5 = h : g$

Express as fraction

$\frac{3}{2.5} = \frac{h}{g}$

Cross multiply

$2.5h = 3g$

No options were given. So, I will stop here

alexdok [17]

The order doesn't matter.

$k$ objects can be chosen out of $n$ objects, when the order doesn't matter, in $C(n,k)=\dfrac{n!}{k!(n-k)!}$ ways.

So, the answer is $C(7,2)\cdot C(5,3)=\dfrac{7!}{2!5!}\cdot\dfrac{5!}{3!2!}=\dfrac{6\cdot7}{2}\cdot\dfrac{4\cdot5}{2}=210$ ways.
