Does anyone know the answer to this scale and unit conversion GED math problem? Thank you very much!
aliya0001 [1]

Answer:

Flour 5\dfrac{1}{2}\ c

Sugar 2\dfrac{2}{3}\ c

Butter 1\dfrac{1}{2}\ c

Eggs 2

Baking powder 7\ t

Vanilla extract 3\ t

Step-by-step explanation:

There will be 16 people at the party. Each person will eat 3 cookies, so all people will eat 16\cdot 3=48 cookies.

Given cookie recipe makes 24 cookies, so to make 48 cookies you need

48:24=2 portions.

Thus,

              1 portion                      2 portions

Flour      2 \dfrac{3}{4}\ c               2\dfrac{3}{4}\cdot 2=2\cdot 2+\dfrac{3}{4}\cdot 2=4+\dfrac{3}{2}=4+1 \dfrac{1}{2}=5\dfrac{1}{2}\ c

Sugar    1\dfrac{1}{3}\ c                  1\dfrac{1}{3}\cdot 2=1\cdot 2+\dfrac{1}{3}\cdot 2=2+\dfrac{2}{3}=2\dfrac{2}{3}\ c

Butter    \dfrac{3}{4}\ c                  \dfrac{3}{4}\cdot 2=\dfrac{3}{2}=1\dfrac{1}{2}\ c

Eggs      1                           1\cdot 2=2

Powder 3\dfrac{1}{2}\ t                  3\dfrac{1}{2}\cdot 2=3\cdot 2+\dfrac{1}{2}\cdot 2=6+1=7\ t

Vanilla   1\dfrac{1}{2}\ t                  1\dfrac{1}{2}\cdot 2=1\cdot 2+\dfrac{1}{2}\cdot 2=2+1=3\ t

Write the equation of the line perpendicular to + = that passes through (−,−). Write your answer in slope-intercept form.
Ad libitum [116K]

Answer:

y = 0.25x - 5

Step-by-step explanation:

Given line is 4x + y = 3

or y = -4x + 3

Comparing this with slope-intercept form y = mx + c :

slope of this line is -4

Product of slopes of perpendicular lines = -1

⇒ slope of a line perpendicular to this is \frac{-1}{-4} = \frac{1}{4} = 0.25

This line also passes through the point (-4,-6)

The equation of a line having slope m and passing through a point (h,k) is

y - k = m(x - h)

⇒ equation of line perpendicular to given line is y - (-6) = 0.25×{x - (-4)}

⇒ y + 6 = 0.25×(x + 4)

⇒ y + 6 = 0.25x + 1

⇒ <u>y = 0.25x - 5</u>

This is in the slope-intercept form y = mx + c with slope m = 0.25 and y-intercept (0,-5)
