During a period of 30 working days, Deborah was late 80% of the time. How many days was she late?
erik [133]
Fairly straightforward question. She works 30 days and is late 80% or 0.8
We can model our equation
Num days late = late percentage * num working days
Basically fine portion of working days that she was late.

Num days late = 0.8 * 30=24

So Deborah was late 24 out of 30 working days. Would appreciate a brainliest

Write an equation in slope intercept form to model the situation.
lozanna [386]

Answer:

y=-\frac{1}{2}x + 10

Step-by-step explanation:

Slope intercept form is a way of modeling a quadratic equation, where the coefficient of the term (x) is the slope (change) of the line, and the constant is the y-intercept. In essence;( y=mx+b ), where (m) is the slope and (b) is the y-intercept.

The slope of the given line is (-\frac{1}{2}) because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is (\frac{1}{2}) because this is the rate of burning, the slope is also negative since the height is decreasing. (10) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is (y=-\frac{1}{2}x + 10), where the output (y) is the current height of the candle, and the input (x) is the time at which the measruement was taken.

If the producer in a food chain has 1000 kcal of energy available, how much energy would each of the consumers have?
madam [21]

Answer:

Primary consumer = 100kcal

Secondary consumer = 10kcal

Tertiary consumer = 1kcal

Step-by-step explanation:

In a food chain, transfer of energy occurs when one organism feeds on another organism. However, only 10% of energy is transferred from one organism to another because energy is lost as heat when the organisms perform metabolism.

In a typical food chain consisting of a producer, a primary (1st), secondary (2nd) and tertiary (3rd) consumer, if there are 1000 kcal of energy available in the producer, then:

- Primary consumer will obtain; 10% of 1000Kcal

10/100 × 1000

Primary consumer = 100kcal of energy.

- Secondary consumer will obtain as follows; 10% of 100kcal available energy

= 10/100 × 100

Secondary consumer = 10Kcal of energy.

- Tertiary consumer will obtain as follows; 10% of 10Kcal of available energy.

= 10/100 × 10

Tertiary consumer = 1 kcal of energy.
