WILL GIVE BRAINLIEST!!!!!!! A boy had 20 cents. He bought x pencils for 3 cents each. If y equals the number of pennies left, wr

kumpel [21]

Answer:

Hey there!!

The total number of cents - 20

Cost for each pencil - 3 cents

Number of pencils bought - ' x '

y = number of pennies left

What is the domain ?

Show how y is dependent on x ..

Let's get this into an equation :

... The total cost for x pencils bought = 3x

... Number of pennies left = 20 - 3x

... y = number of pennies left

... y = 20 - 3x

Notice : If the x value changes, the y value changes too

... If x = 1 , then , y = 17; If x = 2 , then , y = 14

Hence, we could say y is dependent upon x

Domain = ?

... Remember - The total number of pennies = 20 ; hence, the total cost cannot go above 20 cents.

Hence, we will have to work with inequalities

The equation :

... 20 ≥ 3x

Divide 3 on both sides

20 / 3 ≥ x

x ≥ 6.667

Let's take this as 6

Hence , the domain will be :

D : { 1 , 2 , 3 , 4 , 5 , 6 }

Hope my answer helps!

Rhian sat a maths test and an English test In the Maths test she scored 14 out of 17 In the English test she scored 31 out of 39

BabaBlast [244]

Answer:

Rhian did better in the Math test.

Step-by-step explanation:

Given: Rhian scored $14$ out of $17$ in a Math test. In the English test she scored $31$ out of $39$ .

To find: In which test did she do better?

Solution:

We have,

Rhian scored $14$ out of $17$ in a Math test.

Rhian scored $31$ out of $39$ in an English test.

So, first we need to find the percentage of the marks scored.

Percentage in the Math test $=\frac{14}{17}\times100=82.35 \%$ .

Percentage in the English test $=\frac{31}{39}\times100= 79.49\%$ .

Clearly, the percentage in the Math test is greater than the percentage in the English test.

So, Rhian did better in the Math test.
