Answer:
13, 14, 15, 16
Step-by-step explanation:
Call the first number n. Then the next three consecutive numbers (assuming integers) are n + 1, n + 2, n + 3.
The mean is the total of the numbers divided by how many there are.
[tex]\frac{n+(n+1)+(n+2)+(n+3)}{4}=14.5[/tex]
Simplify and multiply by 4.
[tex]4n+6=58\\4n=52\\n=13[/tex]
The first number is 13.
The median is 14.5, halfway between the "middle" numbers 14 and 15. This is just a check; no additional equation is necessary.

find asymptotes for y=x^3 + 3^x
Answer:
No asymptotes
Step-by-step explanation:
The equation provided does not have any asymptotes. Neither for the y-axis or x-axis. It instead goes towards infinity endlessly. Meanining that there is no value that is equal to zero in this equation. The graph below shows the equation graphed, but could not be zoomed out because the equation is endless.

A package states that there are 60 calories in 12 crackers and 75 calories in 15 crackers. Since the relationship is proportional, how many calories are there in 180 crackers?
answer:
900 calories
step-by-step explanation:
there are 60 calories in 12 crackers or 5 calories per crackers
60/12 = 5
there are 75 calories in 15 crackers or 5 calories per crackers
75/15 = 5
if there are 180 crackers
180 • 5
900 calories total
Find BC. AB=25 AC=25 BD=3x+4 DC=4x-5
Answer:
b
Step-by-step explanation:
Since AB = AC = 25, then the triangle is isosceles
Segment AD bisects BC at right angles , then
CD = BD, that is
4x - 5 = 3x + 4 ( subtract 3x from both sides )
x - 5 = 4 ( add 5 to both sides )
x = 9
Then
BC = 3x + 4 + 4x - 5 = 7x - 1 = 7(9) - 1 = 63 - 1 = 62
Answer:
3x+4=4x-5
3x‐(4x)=-5+-4
x=9
plug in 9 for x on both sides and add them together to find BC
each side is 31,
answer is 62.

If r is an odd integer and m=8r then m/2 will always be
a. odd
b. even
c. positive
d. negative
Answer:
b. even
Step-by-step explanation:
m is a multiple of 8, so it is also a multiple of 4. When a multiple of 4 is divided by 2, the result is a multiple of 2 (even).
All numbered streets runs parallel to each other. Both 3rd and 4th streets are intersected by king ave. As shown
Answer:
(a)
∠(a) = 105°
(b) ∠(b) = 75°
(c)
∠(c) = 105°
Step-by-step explanation:
Complete Question
1. All numbered streets runs parallel to each other. Both 3rd and 4th Streets are intersected by King Ave. as shown:
(a) Suppose a car is traveling west on 4th Street and turns onto King Avenue heading south. What is the measure of the angle created by the car's turning? Explain your answer.
(b) Suppose a car is traveling southwest on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.
(c) Suppose a car is traveling northeast on King Avenue and turns right onto 4th Street. What is the measure of the angle created by the car's turning? Explain your answer
Also find the attachment
Solution
(a)
∠(a) + 75° = 180°
∠(a) = 180° - 75°
∠(a) = 105°
(b) As we can see the 3rd and 4th street are parallel thus the corresponding angle will be equal
Thus, ∠(b) = 75°
(c)
∠(c) + 75° = 180°
∠(c) = 180° - 75°
∠(c) = 105°
What is the measure, in degrees, of ZA?
Answer:
28
Step-by-step explanation:
2x + 3x + 40 =180
5x= 180 - 140
5x=140
x= 28
Answer:
Step-by-step explanation:
We know that the sum of interior angles of a triangle is 180° so we can say:
40 + 2x + 3x = 180°
40 + 5x = 180°
5x = 140°
x = 28°
Now substitute in 28 for the value of x in Angle A:
=> 2x would become 2(28)
=> 56° = ∠A
Hope this helps!

Pentagon CDEFG is translated 7 units up and 5 units left, resulting in pentagon C'D'E'F'G' (not shown).
Correctly complete the sentence.
The perimeter of pentagon CDEFG is____________
the perimeter of pentagon C'D'E'F'G'
If the pentagon is translated 7 units up and 5 units left, it is still the same size, it's just in a different position. The attached picture shows shows a translation in which the shape moves, but remains the same size. (I couldn't find one with a pentagon)
Because they are the same size, C'D'E'F'G' has the same perimeter as CDEFG.
I think it's "the same" or "equal to." I didn't define a specific answer because I'm not sure if they gave you any options, but the pentagons are the same size.

((MATHS FORM2 CHAPTER 5 CIRCLE)). HELPPPPPPPPPP I WILL MARK AS BRAINLIEST PLEASE SHOW YOUR WORKING :-)
Kevin wants to build a dartboard. The dartboard consists of two
circles centred at O and three shaded regions as in the diagram.
The diameters BOD and AOC are perpendicular to each other.
Given OE= ED = 10 cm. Calculate the area of the shaded regions
22
in cm². ((Use π= 22/7))
Answer:
Step-by-step explanation:
strategy: Find the area of the entire dartboard, then subtracted the inner circle from that whole. we will have the entire outer circle, so divide that by 2 for half of it. Next divide the inner circle by 4 . Then add that to the outer circle answer from above.
whole circle = [tex]\pi[/tex]*[tex]20^{2}[/tex] = 1257.142857 [tex]cm^{2}[/tex]
inner circle = [tex]\pi[/tex]*[tex]10^{2}[/tex] = 314.2857143 [tex]cm^{2}[/tex]
1257.142857 - 314.2857143 = 942.8571427 outer circle
942.8571427 / 2 = 471.4285 ( half of the outer circle)
now find quarter of the inner circle
314.2857143 / 4 = 78.57142855
add the two parts together
78.57142855 + 471.4285 = 549.9999
The shaded regions = 550 [tex]cm^{2}[/tex]
