The area of a garden can be represented by the expression x2 - 6x - 27. What are the dimensions of the rectangle in terms of x?
Answer:
Step-by-step explanation:
x² - 6x - 27
x² - 9x + 3x - 27
x(x - 9) + 3(x - 9)
(x - 9) (x + 3) = 0
x = 9
x = -3
The dimensions are 9 and 3
Mary made two 8 ounce drinks each in a separate cup. The first cup has 4 ounces f coffee and four ounces of milk. The second cup has 6 ounces of coffee and 2 ounces of milk. After she stirred the two drinks really well, she took out a third cup that was empty. She poured 2 ounces from the first cup ad 4 ounces from the second cup into the third cup. How many ounces of coffee are in the third cup
Answer:
6 ounces
Step-by-step explanation:
First cup = 4 ounces of coffee + 4 ounces of milk
= 8 ounces drink
Second cup = 6 ounces of coffee + 2 ounces of milk
= 8 ounces drink
She poured 2 ounces from the first cup and 4 ounces from the second cup into the third cup.
Third cup = 2 ounces from the first cup + 4 ounces from the second cup
= 2 + 4
= 6 ounces drink
Ounces of coffee are in the third cup = 6 ounces

Answer:
the mean is:48
the median is:35 and 66
the mode is:50
the range is:51
Step-by-step explanation:
the mean =(49+50+45+23+35+ 66+34+74+54+50) over 10 which is equal to 480 over 10 and the answer is 48
the median =the two nunber in the middle since the numbers are even
the mode is the number that repeat it self and 50 repeated 2 time
the range=74-23=51

Which section or sections represent what is not in set HH?
Answer:
2) Sections 3 and 4
Step-by-step explanation:
Section 1 represents what ONLY applies to set HH, section 2 represents what is in BOTH set HH and Set C. So they are automatically out of the question.
Section 3 and 4, however, apply to either set C, or no set at all!

What is the area of the following figure?
Answer:
Area = 136
Step-by-step explanation:
Rectangle on the bottom
Length = 16
Width = 7
Area = L * W
Area = 16 * 7
Area = 112
Triangle on Top
Height = 13 - 7 = 6
Length = 16 - 8 = 8
In a right triangle the area = the product of the 2 shortest sides divided by 2
Area = 1/2 * Length * Height
Area = 1/2 * 8 * 6
Area = 1/2 48
Area = 24
Total Area = 112 + 24 = 136
Find the product of the elements on the main
diagonal of matrix A:
d1 = (a11)(a22)
Answer:
24
Step-by-step explanation:
thats right
The solution is d₁ = 24
The product of the elements on the main diagonal of the matrix is 24
What is multiplication of matrices?
The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix
Given data ,
Let the matrix be represented as A
Now , the value of A is
[tex]A = \left[\begin{array}{ccc}3 &2 \\ 5 &8 \\\end{array}\right][/tex]
Now , on simplifying the matrix A
The main diagonal of the matrix is having the elements ( a₁₁ ) and ( a₂₂ )
So , the product of the elements in the main diagonal is
a₁₁ = 3
a₂₂ = 8
And , the equation will be
d₁ = ( a₁₁ ) x ( a₂₂ )
Substituting the values in the equation , we get
d₁ = 3 x 8
d₁ = 24
Therefore , the value of d₁ is 24
Hence , the product of the diagonal elements of matrix is 24

ODE TO AN OTTER
I ought to be an otter, ‘cause when all is said and done
I could play along the riverbank, or stretch out in the sun.
I’d swim beneath the water, or backstroke up on top.
I’d dive in like a graceful swan, or do a belly flop.
My days would be so peaceful as a furry, swimming mammal
As opposed to bearing burdens like a one-humped desert camel.
I wouldn’t want to herd sheep like a working collie dog
Or end up an amphibian—a turtle, toad, or frog.
But oh, to be an otter! It would be a stroke of luck
Just to spend all day a-swimmin’, or a-rollin’ in the muck.
But oh, as fate would have it, I’m required to spend my time
Doing schoolwork. What a pity. It seems like such a crime.
The month of May has ended, and all across the nation
The schools have shut their doors, and all of the kids are on vacation.
Yet here it’s still the school year, and it can’t end too soon,
But the days are standing still, stretching till the end of June.
Ah, the otter, who, when sunshine makes the heat rise at the shore,
Stays within its coolsome burrow, eating clams and snails and more.
It swims along the river, catching crayfish, frogs, and trout.
I’d be an awesome otter—of that I have no doubt. Right now I watch the summer tapping at each window pane
And count the days till school is out, and I can swim again.
I’ll walk in glorious mud that squeezes coolness through my toes
And skip along the river, free from tests and schoolwork woes.
Till then, I’ll be an otter, but only in my head,
And start the summer early there, along the riverbed.
‘Cause if I was an otter and could romp and roll and roam,
I wouldn’t have to think of what to write for my class poem.
My days would be so peaceful as a furry, swimming mammal / As
opposed to bearing burdens like a one-humped desert camel.
What does the word burdens mean in the sentence above?
A. doubts
B. feelings
C. objects
D. rivers
Yet here it’s still the school year, and it can’t end too soon, / But the
days are standing still, stretching till the end of June.
What does the author mean by the phrase the days are standing still?
F. The days seem to pass by slowly.
G. The days are full of difficult work.
H. The speaker’s school day is longer than at most schools.
I. There are more school days left than the speaker thought.
I’ll walk in glorious mud that squeezes coolness through my toes / And
skip along the river, free from tests and schoolwork woes.
How would the effect of these lines be different if the author had used the word
walk instead of skip?
A. The speaker would seem less carefree.
B. The speaker would seem more friendly.
C. The speaker would seem to miss school.
D. The speaker would seem less serious.
What effect does the author’s use of language such as ‘cause, a-swimmin’, and
awesome create in the poem?
F. It makes the speaker sound casual.
G. It makes the speaker sound persuasive.
H. It makes the speaker seem caring toward all animals.
I. It makes the speaker seem knowledgeable about otters.
The end of the poem is ironic because the speaker.
A. decides to write a poem about an otter.
B. turns into an otter and swims away from school.
C. changes her mind and doesn’t want to be an otter.
D. has finished the poem that seemed too hard to write.

Answer:
x = 45°
Step-by-step explanation:
We presume you want the measure of angle x.
Long arc BAD is intercepted by inscribed angle BCD and by inscribed angle BDE. Hence angle BDE has the same measure as angle BCD.
x + 70° = 115°
x = 45° . . . . . . subtract 70°
_____
It doesn't matter where point C is on short arc BD—the measure of angle C is the same regardless. This is still true even if point C moves to be on top of point D, so that angle BCD and angle BDE are indistinguishable.
Shark tank A contains 9.2 gallon Tof water. Sarah will begin filling tank A at a rate of 2.4 gallons per minute. Shark tank contains 109.2 gallons of water. Bella will begin draining tank B at a rate of 1.6 gallon per minute. After how many minutes will both tanks contain the same amount of water?
Answer:
25 minutes
Step-by-step explanation:
let x = number of minutes
the following equation can be derived from the question
9.2 + 2.4x = 109.2 - 1.6x
the equations are equated together because it is expected the gallons of water in both tanks would be equal after sometime
collect like terms
2.4x + 1.6x = 109.2 - 9.2
4x = 100
x = 100/4 = 25 minutes
