Margie did math homework for 25 minutes science homework for 60 minutes and took a break for 15 minutes write a percent to repre

kaheart [24]

Answer:

Margie spent 60% of time in doing science Homework

Step-by-step explanation:

Given:

Time spent in doing maths homework = 25 minutes

Time spent in doing science homework = 60 minutes

Break Time = 15 minutes

To Find:

A percent to represent the portion of time that Margie spent on science homework = ?

Solution:

Let the portion representing the portion of time that Margie spent on science homework be x

The total time spent in doing both maths and science homework and in break time = Time spent in doing maths homework + Time spent in doing science homework + Break Time

The total time spent in doing both maths and science homework and in break time = 25 +60 +15 = 100 minutes

Then

x = $\frac{\text{time spent in doing science home work}}{\text{total time spent}} \times 100$

x = $\frac{60}{100} \times 100$

x = 60%

What is an equation of the line that is parallel to y= -4x-5 and passes through the point (-2,6)?

hjlf

Answer:

y = -4x - 2

Step-by-step explanation:

This line y= -4x-5 has slope = -4

Parallel line, slope is the same so slope of the new line is also = -4

Passes through the point (-2,6), equation:

y - 6 = -4(x + 2)

y - 6 = -4x - 8

y = -4x - 2

Answer:

y = -4x - 2

A scientist is growing bacteria in a lab for study. One particular type of bacteria grows at a rate of y=2t^2+3t+500. A differen

Leya [2.2K]

ANSWER

Approximately after 15 minutes.

EXPLANATION

The growth rate of the first bacteria is

$y = 2 {t}^{2} + 3t + 500$

The growth rate of the first bacteria :

$y = 3 {t}^{2} + t + 300$

To find the time that, there will be an equal number of bacteria, we equate the two equation;

$3 {t}^{2} + t + 300 = 2 {t}^{2} + 3t + 500$

$3 {t}^{2} - 2 {t}^{2} + t - 3t + 300 - 500 =00$

${t}^{2} - 2t - 200= 0$

We solve for t to get,

$t = 15.177$

$t = - 13.177$

We discard the negative value.

This implies that,

$t \approx15$
