Find the quotient
6 1/2 divided by 3/4

Answers

Answer:

8 2/3

Step-by-step explanation:

First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2  divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.

The area of the hardscape is 3x^2 + 13x + 4. what is the length and width of the hardscape

Answers

Answer:

[tex](3x+1)[/tex]

[tex](x+4)[/tex]

Step-by-step explanation:

Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.

[tex]3x^2 + 13x + 4[/tex]

Just by looking at the polynomial, it is fairly obvious that the factors are;

[tex](3x+1)(x+4)[/tex]

One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,

[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]

Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;

[tex](3x+1)\\\\(x+4)[/tex]

Answers

Answer:

Bushes are $9.

Bonsai trees are $32.

Step-by-step explanation:

Bushes are b and bonsai trees are t.

15b + 8t = $391

9b + 5t = $241

15b + 8t = $391 × 3 and 9b + 5t = $241 × 5

= 45b + 24t = $1173 and 45b + 25t = $1205

(45b + 24t = $1173) - (45b + 25t = $1205)

t = 1205 - 1173

t = $32

Apply to 15b + 8t = $391.

15b + 32 × 8 = $391

15b = $391 = 32 × 8

15b = $391 - 256

15b = $135

x = ($135 ÷ 15) = $9

Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.

3x-y=0

Answers

Answer:

(-2, -6)

Step-by-step explanation:

Given the simultaneous equation

3x-y=0 ... 1

2x+y=-10 ... 2

Add both equations to eliminate y

3x + 2x = 0 - 10

5x = -10

x = -10/5

x = -2

Substitute x = -2 into 1

3(-2)- y = 0

-6 - y = 0

-y = 0+ 6

-y = 6

y = -6

Hence the coordinate (x, y) is (-2, -6)
