Lydia uses 15 grams of protein powder to make a 22-ounce shake. She decides to make shakes for the week and plans to make 198 ou

max2010maxim [7]

We have been given that Lydia uses 15 grams of protein powder to make a 22-ounce shake. She decides to make shakes for the week and plans to make 198 ounces. We are asked to find the grams of protein powder Lydia will use.

We will use proportions to solve our given problem.

$\frac{\text{Amount of protein powder}}{\text{Amount of shake}}=\frac{15\text{grams}}{22\text{ ounces}}$

$\frac{\text{Amount of protein powder}}{\text{198 ounces}}=\frac{15\text{grams}}{22\text{ ounces}}$

$\frac{\text{Amount of protein powder}}{\text{198 ounces}}\times \text{198 ounces}=\frac{15\text{grams}}{22\text{ ounces}}\times \text{198 ounces}$

$\text{Amount of protein powder}=15\text{grams}\times 9$

$\text{Amount of protein powder}=135\text{ grams}$

Therefore, Lydia will use 135 grams of protein powder for the entire week.

Help! Which choice is the most efficient first step to solve this set of equations?

Dmitry [639]

Answer:

Substitute 3x - 5 for y in the second equation.

Step-by-step explanation:

Generally, to solve the system of linear equations of x and y, the first step would be trying to eliminate x (or y).

Then turn the system into the equation of only y (or x).

Next, try to solve for y (or x).

Then substitute the solved y (or x) into the original system to work out x (or y).

**********

3 options (1 addition, 2 subtractions) do not eliminate x or y (x and y still exist after manipulation).

=> Remaining option relating substitution would be a reasonable choice.

He equation sin (40 degree) equals StartFraction b Over 20 EndFraction can be used to determine the length of line segment AC.

Alisiya [41]

Answer:

The value of b is 12.9 cm

The value of a is 15.3 cm

Step-by-step explanation:

see the attached figure to better understand the problem

Find the value of b

we know that

in the right triangle ABC

The function sine of angle of 40 degrees is equal to divide the opposite side to the angle of 40 degrees (AC) by the hypotenuse (AB)

$sin(40\°)=AC/AB$

Solve for AC

$AC=(AB)sin(40\°)$

substitute the given value

$AC=(20)sin(40\°)$

$AC=12.9\ cm$

therefore

The value of b is 12.9 cm

Find the value of a

we know that

in the right triangle ABC

The function cosine of angle of 40 degrees is equal to divide the adjacent side to the angle of 40 degrees (BC) by the hypotenuse (AB)

$cos(40\°)=BC/AB$

Solve for BC

$BC=(AB)cos(40\°)$

substitute the given value

$BC=(20)cos(40\°)$

$BC=15.3\ cm$

therefore

The value of a is 15.3 cm
