The perimeter of a rectangular carpet is 94 yards. Its width is 19 yards.
How long is the carpet?
label required
Answer:
28 yards
Step-by-step explanation:
Perimeter=2(L)+2(W)
94=2(L)+2(19)
94=2(L)+38
-38 -38
56=2(L)
÷2 ÷2

Jeffrey has an aquarium in the shape of a rectangular prism. He is going to place a layer of sand over the base for his iguana. The area of the base of the aquarium can be represented by the expression (42x3−14x2+21x) feet3. If the width of the aquarium is represented by the expression (7x) feet, what is the length of the aquarium?
Answer:
[tex]Length = 6x^2 - 2x + 3[/tex]
Step-by-step explanation:
Given
[tex]Area = 42x^3 - 14x^2 + 21x[/tex]
[tex]Width = 7x[/tex]
Required
Determine the length of the aquarium
The area of a rectangular base is calculated as:
[tex]Area = Length * Width[/tex]
Substitute values for Area and Width
[tex]42x^3 - 14x^2 + 21x = Length * 7x[/tex]
Make Length the subject
[tex]Length = \frac{42x^3 - 14x^2 + 21x}{7x}[/tex]
Factorize the numerator
[tex]Length = \frac{7x(6x^2 - 2x + 3)}{7x}[/tex]
[tex]Length = 6x^2 - 2x + 3[/tex]

convert 10009 out of 17%
Answer:
Step-by-step explanation:
To convert 10,009 to 17%, turn 17% to decimal and multiply that by 10,009 (10,009 * 0.17), which equals 1,701.53
IF you meant to convert the fraction 10,009/17% (read as "10,009 out of 17 percent, ") then simply convert 17% to a decimal (0.17) and divide 10,009 by 0.17 (10,009/0.17) which is about 58,876.47, for full decimal, use a calculator and do 10,009/0.17
The question is kind of confusing so tell me what you meant

The missing side's length is 18.2
Step-by-step explanation: To find a missing side in a right triangle, you use the Pythagorean theorem to solve it. According to the Pythagorean Theorem, [tex]12.6^{2}[/tex] + [tex]13.1^2[/tex] = [tex]x^{2}[/tex], so 158.76 + 171.61 = [tex]x^{2}[/tex] ⇒ 330.37 = [tex]x^{2}[/tex] ⇒ x ≈ 18.2.

GIven
x1=0
y1=6
x2=4
y2=-2
Solve
(y2-y1)/(x2-x1)
=(-2-6)/(4-0)
=-8/4
=-2
Second Step: find the y-intercept
Given
y=-2x+b
Substitute one of the points into the equation
y=-2x+b
(-2)=-2(4)+b
-2=-8+b
b=6

solve by elimination
{10x-4y=-6
{-3x+4y=-1
WORK MUST BE SHOWN
Answer:
x = -1
y = -1
Step-by-step explanation:
10x - 4y = -6 ---------------------(I)
-3x + 4y = -1 ---------------------(II)
Add equation (I) & (II) and y will be eliminated.
10x - 4y = - 6
-3x + 4y = -1 {Add}
7x = - 7
x = -7/7
x = -1
Plugin x =-1 in equation (I)
10*(-1) - 4y = -6
-10 - 4y = -6 {Add 10 to both sides}
-4y = -6 + 10
-4y = 4 {Divide both sides by (-4)}
y = 4/(-4)
y = -1

Write an equation for the function whose graph is described.
The shape of f(x) = |x|, but shifted 19 units up and then reflected in the x-axis
Answer:
f(x)=-|x|+19
Step-by-step explanation:
so shifted 19 units up means
abosolute value of x + 19
and reflected in the x axis means that you have to put the - before the abosolute value.
so -|x|+19

The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions
Answer:
Step-by-step explanation:
L = W+9
area = LW = 36
(W+9)W = 36
W²+9W-36 = 0
W = -12, 3
-12 is an extraneous solution, so W = 3 inches
L = W+9 = 12 inches
Determine whether the following statement is true or false. If the statement is
false, make the necessary change(s) to produce a true statement.

A poll is taken to see which candidate students will elect as class president. 43% of
students say they will vote for Alessandra. The poll has a margin of error of 3%, so the
least and greatest percent she could receive is represented by la – 431 = 3, where a is
the actual percent of students that vote for Alessandra. What is the lowest percentage of
votes she could receive?
Answer:
The lowest percentage of votes she could receive is 40%
Step-by-step explanation:
43% of students say they will vote for Alessandra, with a margin of error of 3%.
This means that between 43% - 3% = 40% and 43% + 3% = 46% of the students will vote for Alessandra.
This means that the lowest percentage of votes she could receive is 40% and the highest is 46%.

The events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.
What is probability?The probability is defined as the chances of happening any event. Mutually exclusive events are those in which the one event is independent of the other event.
The condition for the mutually exclusive event will be:
[tex]P(A|B)=\dfrac{P(A) \ and P(B)}{P(A)}=P(A)[/tex]
We have the data
red, 0.28
black, 0.30
white, 0.22
other 0.20
Here we will check the mutually exclusive event:-
(1)The events red and black
[tex]P(R|B)=\dfrac{P(R\ and\ B)}{P(B)}[/tex]
[tex]P(R|B)=\dfrac{0.28\times 0.30}{0.30}=0.28 =P(R)[/tex]
Hence the event is exclusive.
(2)The events white and other
[tex]P(W|O)=\dfrac{P(W\ and\ O)}{P(O)}=P(W)[/tex]
[tex]P(W|O)=\dfrac{ 0.22\times 0.20}{0.20}=0.22=P(W)[/tex]
Hence the event is exclusive.
(3) The events red and other
[tex]P(R|O)=\dfrac{P(R\ and\ O)}{P(O)}=P(R)[/tex]
[tex]P(R|O)=\dfrac{ 0.28\times 0.20}{0.20}=0.28=P(R)[/tex]
Hence the event is exclusive.
Hence the events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.
