Answer:
kaylas thinking of the number 414
Step-by-step explanation:
414 is divisable by 18 (414 divided by 23)
414 is palindrome
414 is one less than a multiple of 5 (415)
Answer:
414
Step-by-step explanation:
The last digit must be 4 or 9 since it is one less than a multiple of five. Then, it says the number must be divisible by 18, and 18 = 2x9. Only 4 is divisible by 2, so four must be the last digit. Since it's a palindrome, the first digit must also be four. Since it also has to be divisible by nine, 4 + 4 = 8, and 8 + 1 = 9.

5. 4*
6. E = 15*
Step-by-step explanation:
14 divided by 2 = 7 + 90 = 97
5 divided by 2 = 2.5 rounded to nearest tenth makes 3 + 40 = 43
8 divided by 2 = 4 -AB = 4B

MK = 7, DE = 4.2, m∠B = 48°, sin (E) = 4/5Step-by-step explanation:
Question 3
This is a 30° right triangleMK is opposite to 30° angle ⇒ LK = 2MK ⇒ MK = 14/2 = 7Question 4
FE = 5m∠F = 40°DE/FE = tan (F)DE = 5 tan (40°) = 4.2 (rounded)Question 5
AB = 8AC = 12cos (B) = 8/12 = 2/3m∠B = arccos (2/3) = 48° (rounded)Question 6
sin (E) = DF/EF = 4/5How does the graph of g(x)=(x-1)^3+5 compare to the parent function f(x)=x^3
Answer:
it is one to the right and 5 up compared to its parent function.
Step-by-step explanation:
the (x-1)3 means that the graph is shifted one to the right and the + 5 means that you have to shift the garph 5 up also.

35 * 10 = 350
Step-by-step explanation:
We have 5 * 70 split up into multiple ways, and we need to provide an answer at the end of it.
5 * 70 = 5 * (__ * 10)
We have to equal the value of 5 * 70 by inputting the missing number.
What times 10 equals 70?
7.
5 * 70 = (5 * __) * 10
This goes for the same as the one before, what times 5 equals 5 * 70 to the same amount?
7.
5 * 70 = __ * 10 = __
Now for the final part, we take the information from before and implement to here, what is 5 * 7?
35.
Now do 35 * 10 :
35 * 10

graph the line with the slope 3 passing through the point (2,-1)
Answer:
I can't draw at the moment but I'll try to teach how as best as I could.
Draw the Cartesian plane (x and y-axis)Locate the point (2, -1). To do this, go to x=2 then go down by 1 unit. Plot it or mark this point by a dot.Then from this dot, go 3 units to the right. After that, go up by 1 unit and mark that with a dot. By this time, you now have 2 dots.Connect them and that's it.Brandon bought Snacks for his teams practice he bought a bag popcorn for 211 and a six pack of juice bottles of total cost before tax was 1141 right and solve an equation which can be used to determine X how much

Bobby rode his skateboard 4 miles 30 rode her bicycle 10 miles in minutes. Who traveled at a greater average speed? Define an appropriate unit of speed and provide mathematical justification for your answer.
Answer:
Abelito had the greater average speed
Step-by-step explanation:
Given
Bobby:
[tex]Distance =4\ miles[/tex]
[tex]Time = 30\ minutes[/tex]
Abelito
[tex]Distance = 10\ miles[/tex]
[tex]Time = 48\ minutes[/tex]
Required:
Who had a greater average speed
Average speed (S) is calculated as:
[tex]S = \frac{Distance}{Time}[/tex]
We will make use of mph (miles per hour) as the unit of speed.
For Bobby:
[tex]S_B = \frac{4\ miles}{30\ minutes}[/tex]
Convert minute to hour
[tex]S_B = \frac{4\ miles}{0.5\ hr}[/tex]
[tex]S_B = 8mph[/tex]
For Abelito
[tex]S_A = \frac{10\ miles}{48\ minutes}[/tex]
Convert minute to hour
[tex]S_A = \frac{10\ miles}{0.8\ hr}[/tex]
[tex]S_A = 12.5mph[/tex]
By comparison: 12.5mph > 8mph
Hence: Abelito had the greater average speed

Zoey's dog has a water bowl with a diameter of 6 inches. Sam's
dog has a water bowl with a diameter of 10 inches. What is the
approximate difference in the circumference (distance around)
ut of the two water bowls?
Answer:
12.56 inches
Step-by-step explanation:
Circumference: C = 2*pi*r
I will be using 3.14 in place of pi
Divide the diameters by 2, so 3 for Zoey and 5 for Sam
Multiply (2*3.14*3) and (2*3.14*5)
For Zoey you get 18.84 and for Sam you get 31.4
31.4-18.84= 12.56 in difference

Answer:
10a and 5a+2a+3a
Step-by-step explanation:
6a + 4a = 10a
10a = 10a
9a is not equal to 10a
10+a is not equal to 10a
5a+2a+3a = 10a
6a - 4a is not equal to 10a
a^10 is not equal to 10a
Hope this helps! :)
How do i solve this? and what’s the answer?
Answer:
x = 18
Step-by-step explanation:
The line joining 2 midpoints of the non parallel sides of a trapezoid is 1/2 the sum of the two parallel lines.
Put in much simpler language XY = 1/2 (BC + AD)
4x - 2 = 1/2 (6x + 1 + x) Combine the right
4x - 2 = 1/2 (7x + 1) Multiply by 2
8x - 4 = 7x + 1 Add 4 to both sides
8x = 7x + 5 Subtract 7x
x = 5
But what you want is the length of XY
XY = 4x - 2 = 4*5 - 2 = 18
Sorry I noticed too late that I used x for s. The answer would still be 18.
A highway inspector needs an estimate of the mean weight of trucks crossing a bridge on the interstate highway system. she selects a random sample of 49 trucks and finds a mean of 15.8 tons with a sample standard deviation of 3.85 tons. the 90 percent confidence interval for the population mean is:
Answer:
14.90 to 16.70 tons
Step-by-step explanation:
We are given;
Sample size; n = 49
Mean; x¯ = 15.8
Sample standard deviation; s = 3.85
At 90% Confidence interval, z = 1.645
Formula for confidence interval is;
CI = x¯ ± z(s/√n)
Thus;
CI = 15.8 ± 1.645(3.85/√49)
CI = 15.8 ± 0.90
CI = 14.90 to 16.70 tons
8 1/5-2 7/8 fractions
i removed my answer because it was wrong look at the other peoples answers
Answer: 213/40 or 5.325
Step-by-step explanation:
We can find common denominators for 8 1/5 and 2 7/8.
The Lowest Common Denominator for 8 1/5 and 2 7/8 is 40.
8 1/5 = 41/5 = 328/40.
2 7/8 = 23/8 = 115/40.
Now we can subtract.
328/40 - 115/40 = 213/40.
Therefore, the answer is 213/40 or 5 13/40.

Solve the inequality for x and identify the graph of its solution.
[1x + 1]< 2
Choose the answer that gives both the correct solution and the correct graph.
Answer:
x<1
Step-by-step explanation:
[1x + 1]< 2
Simplify both sides of the inequality.
x+1<2
Subtract 1 from both sides.
x+1−1<2−1
x<1
Answer:
x<1

An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles
away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest
degree.
Answer:
4degrees
Step-by-step explanation:
Given the following
Height of the airplane = 37000feet
distance covered on landing = 100miles = 100(5280)
distance covered on landing = 528,000feet
Using the SOH CAH TOA
sin theta = opposite/hyp
sin theta = 37000/528000
sin theta = 37/528
theta = arcsin (37/528)
theta = 4 degrees
Hence average angle at which the airplane must descend for landing is 4degrees
