A) 8 + 9n ≥ 80, so n ≥ 8
B) 8 + 9n ≤ 80, so n ≤ 8
C) 9n ≥ 80 + 8, so n ≥ 9.8
D) 9n ≤ 80 + 8, so n ≤ 9.8

Micheal and Tracy are carpeting their family room that is 14 1/2 feet long and 12 1/4 feet wide. To find the amount of carpet needed micheal says to multiply 15 1/2 and 12 1/4 and Tracy says to multiply 12 1/4 and 15 1/2 . Who is right how much carpet is needed
Answer:
Area of carpet = 177.625 ft²
Step-by-step explanation:
Given:
Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft
Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft
Find:
Area of carpet
Computation:
Area of carpet = lb
Area of carpet = (14.5)(12.25)
Area of carpet = 177.625 ft²
Micheal estimation = 15.5 x 12.25 = 189.875
Tracy estimation = 12.25 x 15.5 = 189.875
Both wrong.
Which matrix respresents the system of equations shown below?
3x - 2y = 12
4x - y = 9
9514 1404 393
Answer:
B
Step-by-step explanation:
If you remove the variables and the equal signs from the equations and put brackets around what is left, you have the matrix that represents the equations:
[tex]\left[\begin{array}{ccc}3&-2&12\\4&-1&9\end{array}\right] \qquad\textbf{matches B}[/tex]

Additional comment
You need to be sure the variables are in the same order in both equations, as they are here. If there are equations with missing variables, you need to use a zero (0) coefficient in the missing variable's location.

Step-by-step explanation:
the depth of water at the end of a boat dock can be modeled by a senusoidal function Y=Asin [B(r+C) ]+D where y represents the depth in feet of the water, hours after midnight on a certain day, the depth is 10 feet at low tide at 6 am and 18 feet at high tide at noon find the amplitude and midline for the general sine function that can be used to model the water's depth.
Answer:
A=4 ft
Midline: y=14
Step-by-step explanation:
When talking about sinusoidal waves, we know the amplitude will be the distance between the midline and the highest or lowest point of the graph. This can be found by first, finding the distance between the lowest point and the highest point:
d= 18ft - 10ft = 8ft
and divide this distance into 2:
[tex]A=\frac{8}{2}[/tex]
A= 4 ft
in order to find the midline, we need to figure the midpoint between the highest and lowest value. We can do so by using the following formula:
[tex]Midpoint=\frac{high+low}{2}[/tex]
so:
[tex]Midpoint=\frac{18+10}{2}[/tex]
Midpoint = 14
so the midline is located at the line:
y=14

Answer:
B (130°)
Step-by-step explanation:
Because the angles are adjacent that means:
m<ADE + m<CDA = m<CDE
Using this equation, we can find what m<ADE is:
m<ADE = m<CDE - m<CDA
m<ADE = 177° - 47°
m<ADE = 130° (B)
Hope this helps :)
Answer:
B
Step-by-step explanation:
CDE is 177, meaning it’s not a straight line so it’s 3 degrees from a perfect line so if CDA is 47 add the 3 degrees and see if CDE was a perfect line what answer would get you 180.
The combined height of one for tree and one Pinetree is 21 m. The height of four for a tree stacked on top of each other is 24 m taller than one Pinetree. How tall are the types of trees that Logan genetically engineered?
Given :
The combined height of one for tree and one Pine tree is 21 m.
The height of four for a tree stacked on top of each other is 24 m taller than one Pine tree.
To Find :
How tall are the types of trees that Logan genetically engineered.
Solution :
Let, height of tree and pine tree is x and y.
So, x + y = 21 ...1)
4x - y = 24 ...2)
Putting value of y from equation 1 to equation 2, we get :
4x - ( 21 - x ) = 24
5x = 45
x = 9 m
y = 21 - x = 21 - 9 = 12
y = 12 m
Therefore, length of tree and pine tree is 9 m and 12 m.

Solve for w:

4
W +6
16
Answer:
Step-by-step explanation:
The chords, when cut anywhere along their length so that there is one intersection point, will produce the following relationship for this question.
(w + 6)*4 = 16*10 Remove the brackets
4*w + 24 = 160 Subtract 24 from both sides
4w = 160 - 24 Combine the right
4w = 136 Divide by 4
w = 136/4
w = 34

The ratio of the measures of the sides of a triangles is 9:7:3. If the perimeter of the triangle is 266 inches, find the value of x
Answer: Depends on which side x is...
Step-by-step explanation:
This is my strategy for finding the values using ratios
Add the ratio together: 9 + 7 + 3 = 19
Divide the perimeter by the sum of the ratio: 266/19 = 14
Now we know what a unit of one is on the ratio: 14
Multiply this unit by the ratio amount
Side with ratio 9: 9 × 14 = 126 inches
Side with ratio 7: 7 × 14 = 98 inches
Side with ratio 3: 3 × 14 = 42 inches

In ΔNOP, the measure of ∠P=90°, the measure of ∠O=37°, and PN = 72 feet. Find the length of OP to the nearest tenth of a foot.
Answer:
119.6
Step-by-step explanation:
Remark
Draw a rough sketch of what is given.
You will find the NP is the side opposite of the triangle.
P is the right angle
OP is the hypotenuse.
Given
NP = 72
<O = 37
Equation
Sin(O) = NP/OP
Sin(72) = .6018
0.6018 = 72/OP Multiply both sides by OP
0.6018*OP = 72 Divide both sides by 0.6018
OP = 72/0.6018
OP = 119.6

please answer guys
Answer:
3x = -2 2/5 or -2.4
Step-by-step explanation:
5x + 8 = 4
5x = 4 - 8
5x = -4
x = -4/5
3x = y If x = -4/5
3 * -4/5 = y
-12/5 = y
-2 2/5 = y
Y = -2

You draw one card from a standard 52-card
deck. In how many ways could the card be a
face card or a red card?
Answer:
23%
Step-by-step explanation:
There are 52 cards in a deck… 12 of these are Face Cards (the J - Q - K of all four suits). The probability of getting one of these is therefore 12 out of 52 — or 12/52, which is 23%.

(4,0)
Oy-x-1
Oy-1
45
o,-1)
Answer:
the third option is the answer, y= 1/4x-1
Step-by-step explanation:
graph line in standard form:
[tex]y = mx + c[/tex]
where m = slope and c = y-intercept
1) find the slope
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
use the two coordinates given in the graph
i/ (0,-1)
x1 = 0
y1 = -1
ii/ (4,0)
x2 = 4
y2 = 0
substitute the values into the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]
[tex] \frac{1}{4} [/tex]
thus, m = 1/4
2) find the y-intercept
* y-intercept is the value of y that cuts through the y-axis
based on the graph, the y-intercept is -1
thus, c = -1
3) substitute the value of m and c into the standard form formula
[tex]y = mx + c[/tex]
[tex]y = \frac{1}{4} x - 1[/tex]
