Answer:

<em>#1:</em>

4x - 15 + 2x + 3 = 48\\\\2x + 18 = 48\\\\2x = 30\\\\x = 15

<em>#2:</em>

Part 1: Solve for x

6x - 7 = 5x + 1\\\\x - 7 = 1\\\\x = 8

Part 2: Plug in x for PQ

6(8) - 7\\\\48 - 7\\\\41

The length of segment PQ is 41.

Part 3: Plug in x for QR

5(8) + 1\\\\40 + 1\\\\41

The length of segment QR is 41.

Part 4: Length of PQ + length of QR = length of PR

PQ + QR = PR

41 + 41 = PR

82 = PR

The length of segment PR is 82.

A 90-day simple interest loan in the amount of $2350 will be paid in full in the amount of $2500 . Find the rate of the loan.
ivolga24 [154]

Answer:

The rate of simple interest is 25.89 %  

Step-by-step explanation:

Given as :

The principal = $2350

The Amount = $2500

The time period = 90 days = \frac{90}{365} year = 0.2465 year

Let The rate of interest = R %

So, Interest = Amount - Principal

Or, Interest = $2500 - $2350 = $150

<u>From Simple Interest method </u>

Simple Interest = \frac{Principal\times rate\times Time}{100}

Or, $150 =  \frac{$2350\times rate\times 0.2465 }{100}

or, $150 × 100 = $579.275  × Rate

So, Rate = \frac{15000}{579.275}

∴    Rate = 25.89 %

Hence The rate of simple interest is 25.89 %    Answer

Goshia [24]

the question in English

Nutritionists recommend that a person should drink an average of 2.5 liters of water in a day, to be well hydrated. How many liters of water should a person drink in a month to comply with a good hydration (Consider a month equal to 30 days) Formulate an algebraic expression to determine the total liters of water that a person should drink a given number of days.

Let

x-------> the number of days

y------> the total liters of water

we know that

y=2.5x  ------> algebraic expression to determine the total liters of water that a person should drink a given number of days

For x=30 days (1 month)

substitute in the formula

y=2.5*30=75\ liters

therefore

<u>the answer is</u>

75\ liters

A stock has a beta of 1.30, the expected return on the market is 10 percent, and the risk-free rate is 4.6 percent. What must th
Ronch [10]

Answer:

11.62%

Step-by-step explanation:

Calculation for What must the expected return on this stock be

Using this formula

Expected return=Risk-free rate+(Expected market return -Risk-free rate)*Beta

Let plug in the formula

Expected return=4.6%+(10%-4.6%)*1.30

Expected return=4.6%+(5.4%*1.30)

Expected return=0.046+0.0702

Expected return=0.1162*100

Expected return=11.62%

Therefore What must the expected return on this stock is 11.62%
