Question:

The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab

Answer:

$Length = 14a^2b$

Step-by-step explanation:

Given

$Area = 112a^3b^2$

$Width = 8ab$

Required

Determine the height

Area is calculated as:

$Area = Length * Width$

Make Length the subject

$Length = \frac{Area}{Width}$

$Length = \frac{112a^3b^2}{8ab}$

$Length = \frac{14a^3b^2}{ab}$

Apply law of indices

$Length = 14a^{3-1}b^{2-1}$

$Length = 14a^2b$

2. The girls decide to only spend $40 between them. On average, what is the most each girl can spend? Write and solve an inequal

pochemuha

Answer:

$40 / x ; $10 / y

Step-by-step explanation:

1.)

For the question, the number of girls aren't given ;

Assume the number of girls = x

The total amount they agreed to spend between themselves = $40

Amount spent on average :

Total amout to be spent / number of girls

Amount spent on average by each girl = $40 / x

2.)

The cost of ice cream isnt given;

Assume, cost per ice cream $y

Amount to be spent on on ice-cream = $10

Number of ice creams that can be purchased :

Amount to be spent on ice-cream / cost per ice cream

$10 / y

How sensitive to changes in water temperature are coral reefs? To find out, scientists examined data on sea surface temperatures

Oduvanchick [21]

The correlation coefficient tells that every increase in sea surface temperature of one degree Celsius will result in an average of 0.1578 fewer centimeters of coral growth per year.

Using technology

The mean= x bar = 26.4667

The mean = y bar= 0.86

The standard deviation= Sx= 0.2251

The standard Deviation Sy= 0.0438

The Correlation Coefficient= r = -0.8111

The slope= b= r* Sy/Sx= -0.15789

The intercept is 5.0389

(d) Every increase in sea surface temperature of one degree Celsius will result in an average of 0.1578 fewer centimeters of coral growth per year.

Here the independent variable is X the sea surface temperature and dependent variable is the Y coral growth.

As the temperature decreases which is along x- axis the growth increases along y axis.

From the given options the option d is the best answer according to the question given.

The same values are calculated using different technology .

A produce store sold 45 red apples. If the ratio of red apples to green apples sold was 5 : 2, what is the combined amount of re

lisabon 2012 [21]

The ratio of Red Apples to Green Apples is 5:2. The proportion of red apple is 5/7.

The store sold 45 red apples.

So the combined amount of red and green apples sold = No of red apples sold divided by the proportion of red apples = 45/ (5/7) = 63

The combined amount of red and green apples sold is 63 apples.
