Answer:

-24

Step-by-step explanation:

a= -3 b= 8 c=-4

This means 2 (-4 ^2) + 5 * 8 / -3

2 (-4 ^2) = 2 (16)

2 (16) = 32

Then:

5 * 8 = 40

this means 32 + 40 = 72

There after 72 divided by -3 is equal to -24.

One serving of the food product contains 1g total saturated fat or 5% daily value (DV) for saturated fat. What is the daily valu

Leona [35]

Answer:

The daily value for saturated fat is 20g.

Step-by-step explanation:

Percentage problems can be solved by rule of three

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.

A percentage problem is an example where the relationship between the measures is direct.

The problem states that 1g is 5% of the daily value for saturated fat. The daily value(100%) for saturated fat is x, so:

1g - 5%

xg - 100%

5x = 100

$x = \frac{100}{5}$

x = 20g

The daily value for saturated fat is 20g.

If an asset declines in value from $5,000 to $4,100 over 9 years, what is the mean annual growth rate in the asset’s value over

Mazyrski [523]

Answer:

2.4 %

Step-by-step explanation:

annual growth is the changes in the value of asset

STEP 1: annual growth rate

= (current value - old value)/old value

= (4100 - 5000)/ 4100

= -0.2195 // 21.95%

Step 2: Mean of x

mean of x= average of x

= total of x / count of x ( x here is the annual growth rate)

= annual growth rate / no of years

= -0.2195/ 9

= -0.02 // 2.4 %
