110 freshmen participated in sports or clubs or both. 55 are involved in sports and 68 are involved in clubs. How many students
Varvara68 [4.7K]

Answer: 42

Step-by-step explanation:

Let A represents the number of freshmen participated in sports and B represents the number of  freshmen participated in clubs.

Then , we have given that

n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110

Using formula

n(A\cup B)=n(A)+n(B)-n(A\cap B)

We have,

110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13

Now, the number of students are involved in just sports is given by :-

n(A)-n(A\cap B)=55-13=42

Hence, 42 students are involved in just sports.

A client would like this logo printed onto a canvas that is at least 70 inches tall. The original logo is 4.5 inches wide by 3.6
vfiekz [6]

Answer:

87.5 by 70 inches

Step-by-step explanation:

No options were given. So, I will calculate the minimum width

Given

Original\ Logo = 4.5 : 3.6

Height = 70 in ---- of the printed logo

Required

Determine the dimension that keeps the requirement

Let x be the width of the printed logo.

So, the ratio can be represented as:

Printed\ Logo = x : 70

Equate both ratios

x  : 70 = 4.5 : 3.6

As fraction

x  / 70 = 4.5 / 3.6

Multiply through by 70

70 * x  / 70 = 4.5 / 3.6* 70

x = 87.5

So, one of the dimension that meets the requirement is a width of 87.5 inches

Susan just got a promotion that increased her annual salary from $52,000 to $68,000. Susan's monthly expenses included a mortgag
Veseljchak [2.6K]

Answer:

c. Susan's debt-to-income ratio decreased by about 15%

Step-by-step explanation:

Susan's previous salary = $52,000

Susan's new salary = $68,000

Susan's mortgage = $1,500

The total of three minimum credit card payment = $350

Her lease payment = $280

Her student loan payment = $250

Her personal loan payment = $325

Therefore, her total debt = $1,500 + $350 + $280 + $250 + $325 = $2,705

Her new Debt to loan ratio = (Her total deb)/(Her total new income) = 2705/68000 = 3.9779 %

Her previous to loan ratio = (Her total deb)/(Her total previous income) = 2705/52000 = 5.2%

The percentage change in her debt to income ratio = (5.202 - 3.9779)/5.202 ≈ 23% decrease

Therefore, the best option is Susan's debt-to-income ratio decreased by about 15%.
