Answer:

\sqrt{65}

Step-by-step explanation:

distance between 2 points:

d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\ \\d=\sqrt{(-7-1)^{2}+(2-1)^{2}}\\\\d=\sqrt{(-8)^{2}+(1)^{2}}\\\\d=\sqrt{65}

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.

A surfboard has a price of $920. With sales tax, it will cost $1,012. What is the sales tax percentage?
Solnce55 [7]

Answer: 10%

Step-by-step explanation:

Let the sale tax                                                    = $x

Cost price  (CP) of the surfboard                       = $920

Sale tax with cost price of the surfboard          = $1,012

Therefore the sale tax   ($x)                                     = $1,012 - $920

                                                                             =$92

Therefore the sale  tax percentage                   = ⁹²/₉₂₀  x 100

                                                                             = 10%
