THIS IS AN EMERGENCY!! YOU GET ALL MY POINTS (AKA 15 I know I'm poor)!!
belka [17]

Answer:

9 grams

Step-by-step explanation:

<u>We can use these equations</u>:

y = ax

  • Where y is the total amount of baking soda (in mg)
  • Where a is the number of servings
  • Where x is the amount of baking soda in one single serving (in mg)

Here we know that y = 1800 and a = 2, so we will need to solve for x

  • Solving for x we get x= \frac{y}{a} and plugging in our known values we get x = \frac{1800}{2} and this simplifies to 900
  • This means one serving contains 900 mg of baking soda

We can now change the equation to solve for the total amount of baking soda required to serve 10 people

  • We know that a = 10 and x = 900
  • The equation is already solved for y, so plugging in our new values we have y = (10)(900) = 9000 mg
  • The recipe will require 9000 mg in order to serve 10 people

Now there are 1000 mg in 1 g, so converting mg to g we have 9000 mg is equivalent to 9 grams

Nakeisha has 42 m of fencing to build a four-sided fence around a rectangular plot of land. The area of the land is 110 square m
Maurinko [17]

Answer:

length=11 width=10

Step-by-step explanation:

Create two equations with length(l) and breath(w) as our unknowns

2l+2w=42

2l=42-2w

2l/2=(42-2w)/2

l=21-w(equation 1)

lxw=110

lw=110

Substitute equation one into equation two

(21-w)w=110

21w-w²=110

Write your equations in standard quadratic form

0=w²-21w+110

solve this as a quadriatic tri nominal

0=(w-10)(w-11)

0=w-10. or 0=w-11

10=W. 11=L

H(x) = x^2+6 g(x) = 8x-5 <br><br> show that hg(x)=19 simplifies to 16x^2 - 20x + 3 = 0
Studentka2010 [4]

Answer:

h(x)=x²+6 and g(x)=8x-5

prove that hg(x)=19

Step-by-step explanation:

step 1: hog(x)=h[g(x)]

step 2: h(8x-5)

step 3: h(8x-5)= (8x-5)²+6

step 4: (8x-5)(8x-5)+6

step 5: 16x² +15x +6
