Answer:

12/55

Step-by-step explanation:

Probability is the ratio of the number of possible outcomes to the number of total outcomes.

Given that the bag contains 8 red balls and 3 white balls, the probability of picking a red ball

p(r) = 8/(8+3) = 8/11

Probability of picking a white ball

= 3/11

when a red ball is picked first, the total number of balls reduces to 10 hence the probability that the second ball is white, given that the first ball is red

=8/11 * 3/10

= 24/110

= 12/55

A rectangular lawn is 65 m long and 34 m wide. Over time, people have walked along a diagonal as a shortcut and have created a s
irina [24]
To calculate the length of the diagonal, use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the diagonal.
c^2 = 65^2 + 34^2
c^2 = 4225 + 1156
c^2 = 5381
c ~ 73.36
To the nearest tenth of a meter, the diagonal has a length of 73.4 m

PLEASE HELP! 25 POINTS!
Marizza181 [45]

Step-by-step explanation:

<u>Step 1:  Convert the mixed number into an improper fraction</u>

<u />1 \frac{5}{7}

\frac{7}{7}+ \frac{5}{7}

\frac{12}{7}

<u>Step 2:  Multiply to find the area</u>

<u />\frac{5}{6}*\frac{12}{7}

\frac{60}{42}

<u>Step 3:  Convert into a mixed number</u>

<u />\frac{60}{42}

\frac{42}{42} + \frac{18}{42}

1 \frac{18}{42}

1\frac{3}{7}

Answer:  1\frac{3}{7}

Find the measure of each side indicated. Round to the nearest tenth.
mihalych1998 [28]

Answer:

D. 25.3

Step-by-step explanation:

tan∅ = opposite over adjacent

Step 1: Write equation

tan66.5° = x/11

Step 2: Multiply both sides by 11

11tan66.5° = x

Step 3: Evaluate

x = 25.2983

x ≈ 25.3

T.J. Had a car loan for $5800. Over the course of the loan, he paid a total of $1508 in interest at a rate of 6.5%. Over how man
kodGreya [7K]

Answer: it took T.J. 48 months to pay the car loan.

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P = principal or amount loaned

R = interest rate

T = time in years.

I = interest

From the information given,

P = $5800

R = 6.5%

Over the course of the loan, he paid a total of $1508 in interest. Therefore,

I = $1508 Therefore,

1508 = (5800×6.5×T)/100

1508 = 377T

T = 1508/377 = 4 years

Assuming there are 12 months in a year, the number of months in 4 years would be 4×12 = 48 months
