LIVING ROOM Maude's living room is in the shape of a rectangle. Its dimensions are 21 feet by 14 feet. Find the length of the diagonal of the living room. Round your answer to the nearest tenth if necessary.
Answer:
25.2 feets
Step-by-step explanation:
Given that:
Rectangular shaped living room has the dimension:
21 feets by 14 feets
Length of diagonal :
Using Pythagoras :
A² = B² + C²
Diagonal² = 21² + 14²
Diagonal = √(441 + 196)
Diagonal = √637
Diagonal = 25.238
Diagonal = 25.2 feets ( nearest tenth)

To eliminate the y-terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before adding the equations
together?
First Equation: 5x - 4y = 28
Second equation: 3x - 9y = 30
The first equation should be multiplied by 3 and the second equation by 5.
The first equation should be multiplied by 9 and the second equation by -4.
The first equation should be multiplied by 3 and the second equation by -5.
The first equation should be multiplied by 9 and the second equation by 5.
Answer:
D
Step-by-step explanation:
took the test
To eliminate the y-terms and solve for x in the fewest steps , the first equation should be multiplied by 9 and the second equation by -4.
The equation is as follows:
5x - 4y = 28
3x - 9y = 30
To eliminate the y-terms and solve for x can be done as follows:
Multiply the equation(i) by 9
45x - 36y = 252
Multiply the equation(ii) by -4
Therefore,
-12x + 36y = -120
Combine the equation45x - 36y = 252
-12x + 36y = -120
y will be eliminated by adding the equations.
Therefore, to eliminate the y-terms and solve for x in the fewest steps , the first equation should be multiplied by 9 and the second equation by -4.

Each letter of the word "supercalifragilisticexpialidocious" is placed into a bag and drawn at 3 times, replacing the letter after each draw. Find the probability that the letter "i" is drawn at least once.
Answer:
P(X ≥ 1) = 0.50
Step-by-step explanation:
Given that:
The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.
Then; the probability of success = 7/34 = 0.20588
Using Binomial distribution to determine the probability; we have:
[tex]P(X = x) = ^nC_x \ \beta^x \ (1 - \beta)^{n-x}[/tex]
where;
x = 0,1,2,...n and 0 < β < 1
and x represents the number of successes.
However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:
P(X ≥ 1) = 1 - P(X< 1)
P(X ≥ 1) = 1 - P(X =0)
[tex]P(X \ge 1) = 1 - \bigg [ {^3C__0} (0.21)^0 (1-0.21)^{3-0} \bigg][/tex]
[tex]P(X \ge 1) = 1 - \bigg [ 1 \times 1 (0.79)^{3} \bigg][/tex]
P(X ≥ 1) = 1 - 0.50
P(X ≥ 1) = 0.50

Last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days. Each day they found 9 shells. How many fewer shells did they find this year than last year?
Answer:
Step-by-step explanation:
Since on each day 9 shells were found, and there are 7 days: 7 x 9 = 63
Number of shells found this summer: 63
Number of shells found fewer this year than last year: 152 - 63 = 89
Hence, Jon’s family found 63 fewer shells than last year
Jon’s family found 63 fewer shells than last year if last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days.
Let x be the number of shells they find this year than last year.
The value of x can be found as follows:
x = 152 - 7×9
x = 152 - 63
x = 89 shells
Thus, Jon’s family found 63 fewer shells than last year if last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days.

Answer:
x = 6 , y = -4
Step-by-step explanation:
Solve the following system:
{-9 y - 3 x = 18 | (equation 1)
3 y + 4 x = 12 | (equation 2)
Swap equation 1 with equation 2:
{4 x + 3 y = 12 | (equation 1)
-(3 x) - 9 y = 18 | (equation 2)
Add 3/4 × (equation 1) to equation 2:
{4 x + 3 y = 12 | (equation 1)
0 x - (27 y)/4 = 27 | (equation 2)
Multiply equation 2 by 4/27:
{4 x + 3 y = 12 | (equation 1)
0 x - y = 4 | (equation 2)
Multiply equation 2 by -1:
{4 x + 3 y = 12 | (equation 1)
0 x+y = -4 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{4 x+0 y = 24 | (equation 1)
0 x+y = -4 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 6 | (equation 1)
0 x+y = -4 | (equation 2)
Collect results:

Answer:
y=-4x+1
Step-by-step explanation:
m=-4
h=1
Answer:
Step-by-step explanation:
b is the y intercept. Start with b. The graph shows that the point (0,b) is (0,1)
So far what you have is y = mx + 1
Now you have to deal with m
m = (y2 - y1)/(x2 - x1)
m = (1 - 0)/(0 - -1/2) = 1 /0.5 = 2 Use your calculator for this.
So the line is y = 2x + 1
As you move into the shaded area y > 2x + 1
I reproduced the graph to show that pointed the arrow in the right way. You can try it to see if it works by trying a couple of points. y should work out to be greater than 2x + 1
Five friends ate lunch together. They each paid the same amount the total cost of all five meals was $51.94 which included a 6% sales tax, what was the cost of one meal before tax was added?
Given:
Total number of friends = 5
Total cost of all five meals = $51.94
Sales tax = 6%
To find:
The cost of one meal before tax was added.
Solution:
Let x be the cost of all five meals before tax.
Then, Amount of tax = 6% of x
According to he question,
[tex]x+\dfrac{6}{100}x=51.94[/tex]
[tex]x+0.06x=51.94[/tex]
[tex]1.06x=51.94[/tex]
Divide both sides by 51.94.
[tex]x=\dfrac{51.94}{1.06}[/tex]
[tex]x=49[/tex]
So, the cost of all five meals before tax is $49.
Divide this cost by 5 to get the cost of one meal before tax was added.
[tex]\dfrac{49}{5}=9.8[/tex]
Therefore, the cost of one meal before tax was added, is $9.8.

Zeno jumped 8 meters. Then he jumped half as far again (4 meters). Then he jumped half as far again (2 meters). So after 3 jumps, he was 8 + 4 + 2 = 14 meters from his starting place.
a. Zeno kept jumping half as far again. How far would he be after 4 jumps?
14/2 = 7
7/2 = 3.5
3.5/2 = 1.75
1.75/2 = 0.875
9514 1404 393
Answer:
15 meters
Step-by-step explanation:
Zeno's last jump was 2 meters, so another jump half as far adds 1 meter to the 14 m total.
After 4 jumps, Zeno would have jumped 15 meters from his starting place.

Comment on the question
The given distances give a total "after 3 jumps." The question asks for a total "after 4 jumps." It is not clear whether that is 4 jumps total, or 4 more jumps. In the above, we have assumed it is 4 jumps total.

What is the value of the expression 5y² + 4x when x = 2.5 and y = 3?
Answer:
55
Step-by-step explanation:
the value of the expression 5y² + 4x when x = 2.5 and y = 3 will be 55.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given an expression 5y² + 4x
To calculate the value of expression at x = 2.5 and y = 3
Substitute the value of x and y in the expression:
=> 5y² + 4x
=> 5* 9 + 4 * 2.5
=> 45 + 10
=> 55
therefore, 55 is the value of the expression 5y² + 4x when x = 2.5 and y = 3.
