Ms. Sampson recorded the percentage change in her students

kvv77 [185]

Answer:

The student whose marks between quarter grades & topic tests score has maximum proportionate deviation

Step-by-step explanation:

Percentage change shows the proportionate change in a value, from the initial point. Formula = ( Change / Old ) x 100

Percentage change in students' quarter grades from topic tests score =

[ ( Quarter topic test score - Topic test score ) / Topic Test score ] x 100

Eg : Quarter Grade = 80, Test score = 60.

Percentage change = [ (80 - 60)/ 60 ] x 100 = ( 20 / 60 ) x 100 = 33%

So, student who has this maximum proportionate or percentage deviation between quarter grades & topic tests score - that student change would be represented by the point farthest from 0 on a number line.

2. What is the area of a circle whose diameter is 14π cm?

34kurt

Answer:

Diameter = 14 cm

Radius(r) = Diameter/2

=> 14/2 = 7cm

Circumference of circle

=> 2 π r

=> 2 × \frac{22}{7}

× 7

=> 2 × 22

=> 44 cm

Therefore, circumference of circle= 44 cm.

___________________

Area of circle = π r ²

=> \frac{22}{7}

× 7 × 7

=> 22 × 7

=> 154 cm²

Therefore, Area of circle = 154 cm²

Las edades de dos hermanos tienen una razón de 2 a 1. Cuando transcurran 4 años, la razón entre sus edades será de 8 a 6. ¿Cuánt

Nataly [62]

Answer:

The age of brothers are 4 years and 2 years respectively.

Step-by-step explanation:

We are given that the ages of two brothers have a ratio of 2 to 1. When 4 years have passed, the ratio of their ages will be 8 to 6.

Let the age of the first brother be 'x years' and the age of the second brother be 'y years'.

So, according to the question;

The first condition states that the ages of two brothers have a ratio of 2 to 1, that means;

$\frac{x}{y} =\frac{2}{1}$

$x=2y$ -------------- [equation 1]

The second condition states that when 4 years have passed, the ratio of their ages will be 8 to 6, that means;

$\frac{x+4}{y+4}=\frac{8}{6}$

$6({x+4})=8}(y+4)$

$6x+24=8y+32$

$6(2y)+24=8y+32$

$12y-8y=32-24$

$4y=8$

$y=\frac{8}{4}$ = 2 years

Putting the value of y in equation 1 we get;

x = 2y

x = $2 \times 2$ = 4 years

Hence, the age of brothers are 4 years and 2 years respectively.
