Lori works as a cartoonist for a teen magazine.The time she spent sketching is given by the equation m=12s, where mis the number of minutes and s is the number of sketches. If lori made 3/4 of a sketch, she spent minutes sketching

Answers

Answer:

Lori spends 9 minutes on sketching $(3)/(4)$ th of a sketch.

Step-by-step explanation:

Given equation:

$m=12\ s$

where $m\rightarrow$ number of minutes Lori spends on sketching

and $s\rightarrow$ number of sketches Lori makes.

We need to calculate the time spent by Lori in sketching $(3)/(4)$ of a sketch.

So we know the value of $s=(3)/(4)$ as $s$ represents number of sketches and in this situation Lori has sketched only a fraction of a painting.

So we plugin $s=(3)/(4)$ in the equation and calculate $m$ which is time spent by Lori sketching $(3)/(4)$ th of a sketch.

$m=12\ (3)/(4)$

$m=(36)/(4)$

∴ $m=9$ minutes (Answer)

∴ Lori spends 9 minutes on sketching $(3)/(4)$ th of a sketch.

A rectangular game board is composed of identical squares arranged in a rectangular array of r rows and r+1 columns. The r rows are numbered from 1 through r, and the r+1 columns are numbered from 1 through r+1. If r>10, which of the following represents the number of squares on the board that are neither in the 4th row nor in the 7th column?A. r^2 - r
B. r^2 - 1
C. r^2
D. r^2 + 1
E. r^2 + r

Answers

The correct answer is A r^2 - r. Here is the procedure to give you an idea on to why is it like that:
Lets say that total rows : r
And lets say that total columns : r + 1
Now the total squares = r(r+1) ------------(1)
squares in 4th row = r+1
squares in 7th column = r
squares common to above = 1
total squares in 4th row, and 7th column = 2r ------- (2)
Now what we cca do after describing all this facts is that
- 1 from both row will be r-1
column will be r
and then multiply (will be r*r-1 or r^2-r)!
I hope this can help you greatly

Three weeks ago John bought stock at 49 1/4; today the stock is valued at 49 7/8. We could say the stock is performing at which of the following?A. Below par
B. Par equality
C. On par
D. Above par

Answers

Answer:

The correct option is D.

Step-by-step explanation:

John bought stock at $49(1)/(4)$ ; today the stock is valued at $49(7)/(8)$ .

$49(1)/(4)=49+(1)/(4)$

$49(1)/(4)=49+0.25$

$49(1)/(4)=49.25$

The value of stock at the time of purchasing is 49.25.

$49(7)/(8)=49+(7)/(8)$

$49(7)/(8)=49+0.875$

$49(7)/(8)=49.875$

The value of stock at current time is 49.875.

$49.875-49.25=0.625$

The value of stock increased by 0.625.

Since the value of stock increases, therefore the correct option is D, i.e., Above par.

The best answer to the question that is being presented above would be letter D above par. The stock is performing at above par because there is an increase in the value of the stock by twenty nine percent (29%).
