Answer:
28 minutes
Step-by-step explanation:
new length of time = percent reduction x initial time
percent reduction = 100 - 8 = 92%
0.92 x 32 = 29.44
New time after final reduction
(100 - 5%) x 29.44
27.96 = 28 minutes
Estimate the product 48 x 29 by rounding each factor to the nearest ten.

Draw a line representing the “rise” and a line representing the “run” of the line. State the slope of the line in the simplest form.
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The slope is the "rise" over the "run" of the line, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.
[tex]\frac{rise}{run}[/tex]
We can see that, on the graph, for every 3 units the line travels to the right, it travels 2 units up. Therefore, the rise is 2 while the run is 3.
[tex]\frac{2}{3}[/tex]
Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

The daily fee for docking a boat at a marina in port Canaveral is proportional to the length of the boat. The table displays the fee for four different boat lengths. find the constant of proportionality and explain what it means in the context of this problem.
Answer:
Constant of proportionality = 2.25
What this value means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25
Step-by-step explanation:
We are told that the daily fee for docking a boat at a marina in port Canaveral is proportional to the length of the boat.
Let D be represent the daily fee and let the lent be L.
D ∝ L
Let the constant of proportionality be k.
Thus;
D = kL
k = D/L
For length of 15 ft;
k = 33.75/15
k = 2.25
For length of 17 ft
k = 38.25/17
k = 2.25
For length of 20 ft
k = 45/20
k = 2.25
Foe length of 21 ft
k = 47.25/21
k = 2.25
This means the formula for the relationship between the daily fee and boat length is; D = 2.25L
Thus, D/L = 2.25
What this means is that the ratio between the daily fee for docking a boat at a marina in port and the length of the boat is 2.25
Find the equation of the line by using y=mx+b
I tried to put the answer but it keeps asking for more
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1), we have points (-3,6) and (9,-5)
m=(-5-6)/(9-(-3))
m=-11/12 so now we have
y=-11x/12+b, using point (9,-5) we can solve for b
-5=-11(9)/12+b
-5=-99/12+b
b=39/12
y=(-11x+39)/12
That is the line, m=-11/12 and b=39/12 or as a decimal b=3.25. You had b so not sure what the problem is. Though the question in the picture asks what the line is. The line is
y=-11x/12+13/4 so maybe they want the entire function instead of entering what b is.

The high temperatures for the first 8 days of January and July are shown in the table. Predict which data set has a greater mean absolute deviation. Justify your answer.
Answer:
January has the greater MAD.
Step-by-step explanation:
The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.
13/100 + 11/10 helpppp
Answer:
13/100 + 11/10 = 123/100
Step-by-step explanation:
Answer:
123/100
Step-by-step explanation:
make them both go into 100
13/100 = 13/100
11/10 = 11[tex]11*10 = 11010*10 +100\\110/100[/tex]
add 13/100 to 110/100
you get 123/100 or 1.23
Thomas drew a triangle which has one angle that measures more than
90° and two angles that each measure less than 90°. What kind of
triangle did he draw?
Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!

Answer:
A = 20°
AC = 6.6
BC = 2.4
Step-by-step explanation:
Given:
B = 70°
C = right angle = 90°
AB = 7
Required:
A, AC, and BC
Solution:
✔️A = 180 - (90 + 70) (sum of triangle)
A = 20°
✔️Use trigonometric function to find AC:
Refernce angle = 70°
Opp = AC
Hypotenuse = 7
Apply SOH,
sin 70 = Opp/Hyp
sin 70 = AC/7
7 * sin 70 = AC
6.57784835 = AC
AC = 6.6 (nearest tenth)
✔️Use trigonometric function to find Bc:
Refernce angle = 70°
Adj = BC
Hypotenuse = 7
Apply CAH,
cos 70 = Adj/Hyp
cos 70 = BC/7
7 * cos 70 = BC
2.394141 = BC
BC = 2.4 (nearest tenth)

Bridget is saving for a bike that costs $550. She has $150 in her savings account and saves $40 per month. How many months will it take Bridget to save enough money to buy the bike?
Answer:
9 months im pretty sure hoped this help
Answer: It would take 10 months for her to get enough money to but the bike.
Step-by-step explanation: 150 + 400 = 550.
$40 per month - 40 x 10 = 400.
Already has 150$ in account.
150 + 400 = 550.
The volume of a cylinder is 7271 cmIf the radius is 3 cm, what is the height
of the cylinder?
3 cm
O A 40m
B 3C
Answer:
3cm approx
Step-by-step explanation:
Given data
Volume= 72cm^3
Radius=3cm
Required the height
The expression for the volume is
Volume= πr^2h
substitute
72=3.142*3^2*h
72=28.278h
h= 72/28.278
h=2.54
Hence the height is 3cm approx

Solving systems of equations by graphing. how do you do this
Answer:
Solve systems of equations by graphing
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Example
[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]
Graph the equations in a coordinate plane
The two lines intersect in (-3, -4) which is the solution to this system of equations.

Find the circumference of a circle that has an area of 153.86 cm.
Answer:
C=[tex]14\pi[/tex] or ≈43.96cm
Step-by-step explanation:
Start by figuring out the Area of the circle to get the radius (r)
Area (A)=153.86 cm
A=[tex]\pi r[/tex]²
153.86=[tex]\pi[/tex]r²
153.86÷[tex]\pi[/tex]=r²
49=r²
√49= r
r= 7cm
Next insert r=7cm into the Circumference equation of a circle
C=2[tex]\pi[/tex]r
C= 2×[tex]\pi[/tex]×7
C=14[tex]\pi[/tex] or C=43.96cm
