A cruise ship can travel at a constant speed of 24 miles per hour. Approximately how many days will it take for the cruise ship to travel 1,200 miles?
9514 1404 393
Answer:
2 1/12 days
Step-by-step explanation:
Time is the ratio of distance to speed.
(1200 mi)/(24 mi/h) × (1 day)/(24 h) = 25/12 day = 2 1/12 days
find the area of the shaded portion the one who answer first will get brainliest
Answer:
≈ 77 cm²
Step-by-step explanation:
The area of the shaded portion is calculated as
area of outer sector - area of inner sector
= (πR² - π r²) × [tex]\frac{60}{360}[/tex] ( R is the outer radius, r is the inner radius )
= (π × 14² - π × 7² ) × [tex]\frac{1}{6}[/tex]
= (196π - 49π ) ÷ 6
= 147π ÷ 6
≈ 77 cm² ( nearest whole number )
Answer:
[tex]A_s=76.97\ cm^2[/tex]
Step-by-step explanation:
Circular Sector
It's the portion of a circle enclosed by two radii and an arc. The area of a sector is calculated as follows:
[tex]\displaystyle A=\frac {r^{2}\theta }{2}[/tex]
Where r is the radius and θ is the central angle expressed in radians. The central angle will be converted to radians:
[tex]\theta=60*\frac{\pi}{180}=1.0472\ rad[/tex]
The shaded region in the figure can be obtained by subtracting the smaller sector A2 area from the larger sector area A1:
[tex]A_s=A_1-A_2[/tex]
The larger area is calculated with a radius of r1=14 cm:
[tex]\displaystyle A_1=\frac {14^{2}*1.0472 }{2}[/tex]
[tex]\displaystyle A_1=102.626\ cm^2[/tex]
The smaller area is calculated with r2=7 cm:
[tex]\displaystyle A_2=\frac {7^{2}*1.0472 }{2}[/tex]
[tex]\displaystyle A_2=25.656\ cm^2[/tex]
The shaded area is:
[tex]A_s=102.626\ cm^2-25.656\ cm^2[/tex]
[tex]\boxed{A_s=76.97\ cm^2}[/tex]

Answer:
The inequality describes all possible value of x is 14 < x < 32 ⇒ D
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesIn the given figure
∵ ABC is a triangle
∵ AC = 9 and BC = 21
∵ AB is the third side of the triangle
→ By using the rules above
∴ BC - AC < AB < BC + AC
∵ AB = x - 2
→ Substitute their values in the inequality above
∵ 21 - 9 < x - 2 < 21 + 9
∴ 12 < x - 2 < 30
→ Add 2 to the 3 terms
∴ 12 + 2 < x - 2 + 2 < 30 + 2
∴ 14 < x < 32
∴ The inequality describes all possible value of x is 14 < x < 32

Answer:
(3,-5)
Step-by-step explanation:
its the last answer
Answer:
(3,-5)
Step-by-step explanation:
Hi there!
Since the dot is in the fourth quadrant, our x value will have to be positive. If the value was negative, it would be in the third quadrant.
If you think about the dot’s relation to the y axis, it is below the point of origin, or y = 0, so the y-value will have to be negative.
The only answer that fits this criteria is (3,-5)
I hope this helps!
Which of the following scenarios represents a causation between the two data sets?
Answer:
I think is the first one
Step-by-step explanation:
4y -9x =-23 x=y-3 what is the y-value
Answer:
y = 10
Step-by-step explanation:
Use the substitution method since you already know what x equals.
4y - 9(y - 3) = -23
Simplify:
4y - 9y + 27 = -23
Combine like terms:
-5y + 27 = -23
Isolate y by subracting 27 from both sides:
-5y = -50
Divide by -5 to get y by itself:
-5/-5 = y
-50/-5 = 10

Pineview Middle School has 158 fewer students enrolled than Wellington Middle School. If Pineview Middle has 1039 students enrolled, how many students are enrolled at Wellington Middle?
At Martin Luther King Jr. High School 7 out of 9 students voted to plant trees at the front of the school. A total of 119 voted to plant the trees. How many students voted?
A. 153
B. 272
C. 128
D. 135
Answer:
A
Step-by-step explanation:
If 7 out of 9 voted to plant, that means 2 voted against
so the ratio we are looking at here for vote for and vote against is 7:2
So let the total that voted be x
7/9 * x = 119
x = (9 * 119)/7
x = 153

Find the slope and the y-intercept of the line.
5x - 4y= -8
Write your answers in simplest form.
Answer: The slope is 5/4 and the y intercept will be 2
Step-by-step explanation:
First convert the equation to slope intercept form ( y = mx+b) where m will be the slope and b will be the y intercept.
5x - 4y = -8 Subtract 5x from both sides
-5x -5x
-4y = -5x - 8 Divide both sides by -5
y = 5/4x + 2

Step-by-step explanation:
The value of computer decreases with its age until it is worth nothing a computer that was purchases new for 0 years is worth 2220 1540 after 6 years problem whats the value after 8 years and what is the linear function V(x)
Answer:
[tex]V(x) = -\frac{340}{3}x +2220[/tex]
[tex]V(8) = 1313.3[/tex]
Step-by-step explanation:
Given
Let x represent years and V represents the value.
So, we have:
[tex](x_1,v_1) = (0,2220)[/tex]
[tex](x_2,v_2) = (6,1540)[/tex]
Solving (a): The linear function
First, we calculate the slope (m)
[tex]m = \frac{v_2 - v_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{1540-2220}{6-0}[/tex]
[tex]m = \frac{-680}{6}[/tex]
[tex]m = -\frac{340}{3}[/tex]
The linear function is calculated using:
[tex]v - v_2 = m(x - x_2)[/tex]
Where:
[tex](x_2,v_2) = (6,1540)[/tex]
[tex]m = -\frac{340}{3}[/tex]
So, we have:
[tex]v - 1540 = -\frac{340}{3}(x - 6)[/tex]
Open bracket
[tex]v - 1540 = -\frac{340}{3}x +\frac{340}{3}* 6[/tex]
[tex]v - 1540 = -\frac{340}{3}x +680[/tex]
Make v the subject
[tex]v = -\frac{340}{3}x +680+1540[/tex]
[tex]v = -\frac{340}{3}x +2220[/tex]
So, the function is:
[tex]V(x) = -\frac{340}{3}x +2220[/tex]
Solving (b): When x = 8
Substitute 8 for x in [tex]V(x) = -\frac{340}{3}x +2220[/tex]
[tex]V(8) = -\frac{340}{3}*8 +2220[/tex]
[tex]V(8) = -\frac{340*8}{3} +2220[/tex]
[tex]V(8) = -\frac{2720}{3} +2220[/tex]
Take LCM
[tex]V(8) = \frac{-2720+2220*3}{3}[/tex]
[tex]V(8) = \frac{-2720+6660}{3}[/tex]
[tex]V(8) = \frac{3940}{3}[/tex]
[tex]V(8) = 1313.3[/tex]
Hence, its value after 8 years is 1313.3

Triangle ABC is similar to triangle DEF What are the lengths of sides DF and EF ?
Answer:
A)
Side DF=3
Side EF=6/5
Bye
The values of DF and EF are 3 and 6/5 respectively. (option A)
What are similar triangles?When two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.
Given that, Δ ABC ~ Δ DEF
The proportion = AB/DE = BC/EF = AC/DF = 5/3
2/EF = 5/3
EF = 6/5
5/DF = 5/3
DF = 3
Hence, The values of DF and EF are 3 and 6/5 respectively. (option A)
