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

Find a vector equation and parametric equations for the line through the point (7,4, 5) and parallel to the vector 3i 2j-k .

aleksley [76]

Answer: vector equation r = (7+3t)i + (4+2t)j + (5 - 5t)k

parametric equations: x = 7 + 3t; y = 4 + 2t; z = 5 - 5t

Step-by-step explanation: The vector equation is a line of the form:

r = $r_{0}$ + t.v

where

$r_{0}$ is the position vector;

v is the vector;

For point (7,4,5):

$r_{0}$ = 7i + 4j + 5k

Then, the equation is:

r = 7i + 4j + 5k + t(3i + 2j - k)

r = (7 + 3t)i + (4 + 2t)j + (5 - 5t)k

The parametric equations of the line are of the form:

x = $x_{0}$ + at

y = $y_{0}$ + bt

z = $z_{0}$ + ct

So, the parametric equations are:

x = 7 + 3t

y = 4 + 2t

z = 5 - 5t

jarptica [38.1K]

Answer:

47% of American adult population

Step-by-step explanation:

The reason why polls are carried out is to obtain information that can represent the opinions, status or habits of the population. The polls do not include the total population, then include a small number of participants, but the results are extrapolated to the general population. There are always small margins of error resulting from polls, that is why the confidence levels are usually +/- 3 or 4%.
