Angie and Brian are running a bakery. They are going to make three kinds of banana bread: regular, one with extra sugar, and one

dolphi86 [110]

Answer:

150 regular loaves

125 loaves with extra sugar

100 loaves with extra bananas.

Step-by-step explanation:

Let R represent loaves of regular bread, S represent loaves with extra sugar, and B represent loaves with extra bananas. If they have 1200 bananas, 1050 cups of sugar, and 1075 cups of flour available, the number of each type of bread that Angie and Brian can make are given by the following system of equations:

$3R+2S+5B=1,200\\3R+4S+1B=1,050\\2R+3S+4B=1,075$

Solving the linear system:

$3R+4S+1B-(3R+2S+5B)=1,050-1,200\\2S-4B=-150\\S=-75+2B\\\\3R+2*(-75+2B)+5B=1,200\\2R+3*(-75+2B)+4B=1,075\\3R+9B=1,350\\2R+10B=1,300\\\\3R+9B-1.5*(2R+10B)=1,350-(1.5*1,300)\\9B-15B=-600\\B=100\\2R+10*100=1,300\\R=150\\3*150+2S+5*100=1,200\\S=125$

They should make 150 regular loaves, 125 loaves with extra sugar, and 100 loaves with extra bananas.

the probability that a twelve year old has a brother or sister is 25%. suppose you survey 300 twelve year olds. about how many d

Genrish500 [490]

Answer:

n(B U S) = 75

Step-by-step explanation:

Explanation:-

Probability:-

P(E) = $\frac{number of elements events in E}{total number of elementary events in the random experiment}$

$P(E) = \frac{m}{n}$

Let 'B' be the event of having twelve year old brother

Let 'S' be the event of having twelve year old sister

given data P(BUS) = 0.25

given total survey n(survey) = 300

we have to find the value is n(BUS) =?

we will use probability definition we get, P( BUS) = $\frac{n(BUS)}{n(survey)}$

substitute given values, we will get solution

$0.25 = \frac{n(BUS)}{300}$

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75

If x+3/3=y+2/3, then x/3= A) y/3 B)y-1 C)y/2 D)y+1

Vlada [557]

Answer:

y/2

Step-by-step explanation:

x+3=y+2

------ --------

3 2

Using cross products

2(x+3) = 3(y+2)

Distribute

2x+6 = 3y+6

Subtract 6 from each side

2x+6-6 = 3y+6-6

2x= 3y

Divide each side by 2

2x/2 = 3y/2

x = 3/2 y

We want to find x/3

Divide each side by 3

x/3 = 3/2 y * 1/3

x/3 = 1/2 y
