Naily [24]

Answer:x=90° y=58° z=32°

Step-by-step explanation:

x=90

y=180-(90+32) sum of angles in a triangle is 180

y=58

y+90+z=180 they are supplementary

58+90+z=180

148+z=180

z=180-148

z=32

Dorothy's dietary intake for one day consisted of 250 grams of carbohydrate, 60 grams of protein, and 40 grams of fat. What perc

tester [92]

Answer:

$\%Percent = 17.14\%$

Step-by-step explanation:

Given

$Carbohydrate = 250\ g$

$Protein = 60\ g$

$Fat = 40\ g$

Required

Determine the percentage of protein

First, we need to calculate the total:

$Total = Carbohydrate + Protein + Fats$

$Total = 250\ g + 60\ g + 40\ g$

$Total = 350\ g$

Percentage of protein is calculated as thus:

$\%Percent = \frac{Protein * 100\%}{Total}$

$\%Percent = \frac{60 * 100\%}{350}$

$\%Percent = \frac{6000\%}{350}$

$\%Percent = 17.14\%$

The football team lost 4 yards on 2 plays in a row. Which of the following could represent the change in field position?

Over [174]

Lost (⬅key word) 4 is equal to -4
On 2 plays that is times 2
So all together is -4×2
A negative times a positive is negative
-4×2= -8
Hope this helped you☺
