Answer:
12th triangular number is 78
50th triangular number is 1275
Step-by-step explanation:
12+1=13
12÷2=6
6x13=78
if you do this for 50 you get 1275
Answer:
Step-by-step explanation:
12 number
Wherever you see an n put in 12
12 (12 + 1)/2
12 * 13 / 2
6 * 13
78
The 12th triangular number is 78
50th triangular number
Again, wherever you see an n put in 50
n/2 * (n+ 1)
50/2 * (50 + 1)
25 * 51
1275

Car A travels 20 mph faster than Car B. In the same time that Car A travels 208 mi, Car B travels 156 mi. Find their speeds. The speed of Car A is and the speed of Car B
Step-by-step explanation:
Assuming the speed of car B to be x and the speed of car A to be x+20
156 = 208
x. x+20
156(x+20)= 208x
156x+3120=208x
3120=208x-156x
3120=52x
x=60
The speed of car A is (x)= 60
The speed of car B is(x+20)= 80
Answer:
[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:equationPEMDASlet's solve:let the speed of car A be A
let the speed of car B be B
according to the first condition:
[tex]\quad A=B+20[/tex]
according to the second condition:

g(x) = x – 2
What is the product (fºg)(x)?
Answer:
Correct answer is the first one x^2 + 2x - 8
because (x + 4) (x - 2)
= x ^2 + 4x - 2x - 8

Step-by-step explanation:
explanation is in the picture
Answer:
x = 36.3
Step-by-step explanation:
Use sine
Sine 73 = x / 38
Sine of 73 is 0.956
Which means
0.956 = x / 38
Multiply 38 on both sides
36.328 = x
Round 36.328 to the nearest tenth
36.328 = 36.3

17. A = 180 cm.²
18. A = 252 cm²
Step-by-step explanation:
16. We want to split the triangle and square. We know that the triangle is a right triangle because its linear pair is 90°, which makes it also 90°.
Because this is a rectangle, opposite sides are congruent. So now we have the side measures of 12, 17, 12, and 17.
Refer to the image below for the rest.
Don't forget to add up the two areas for the total area of the whole figure.
17. We want to split the trapezoid and rectangle. This is a rectangle because it has four right angles.
Because this is a rectangle, opposite sides are congruent. So now we have the side measures of 20, 6, 6, and 20.
Now we can also prove that the bottom base of the trapezoid has a measure of 20 because of Reflexive Property.
Refer to the image below for the rest.
Don't forget to add up the two areas for the total area of the whole figure.
18. We want to split this hexagon into two rectangles. We know that they're rectangles because they have four right angles.
Remember, you can't assume that it's a square just because it looks like one. It is not to scale.
To find the length of the larger rectangle, we can add the separate measures of the side to find the total length.
Because it's a rectangle, we now have the measures of 12, 12, 18, 18.
Because the bottom side of the larger rectangle is 12 and the sum of both bottom sides of both rectangles is 18, that makes the bottom side of the second rectangle 6.
Because opposite sides of a rectangle are congruent, this rectangle is a square because it has four congruent sides and four right angles.
Refer to the image below for the rest.
Don't forget to add up the two areas for the total area of the whole figure.
What is the sum of 8 5/6+ 5 11/24?
Enter your answer in the box as a mixed number in simplest form.
Answer:
14 7/24
Step-by-step explanation:
There are two different denominators here: 6 and 24. The LCD is 24, and so 8 5/6 becomes 8 20/24.
Then the SUM of the two given mixed numbers is:
8 20/24 + 5 11/24 = 13 31/24, or, when properly reduced, 14 7/24

4x+y=-1
-5x-2y=-4
Answer: ( -2, 7 )
Step-by-step explanation:
Solve 4x + y = -1 for y:
Add -4 to both sides:
4x + y + -4 = -1 + -4
y = -4x - 1
Now plug -4x -1 in the other equation with y:
-5x - 2 ( -4x -1 ) = -4
3x + 2 = -4
Add -2 to both sides:
3x + 2 - 2 = -4 + -2
3x = -6
Now divide both by 3:
3x/3 = -6/3
x = -2
Now plug in -2 in the first equation with x:
y = - 4 ( -2 ) - 1
y = 7

Megan considers two different car rental options. One option costs $19 per day plus $0.12 per kilometre. Another option costs $42.50 per day for unlimited kilometres.
Compare the two options for a one-day rental. Which option should Megan choose? Why?
Give me answer in full explanation please!
Answer:
The $19 car
Step-by-step explanation:
For a one day rental I'd say its pretty average to only be driving for about 160km which is about 100 miles. For those 160km you would only be paying $19. The combined total $38, which is still less than the $42.50 car. The only way this would somewhat equal out is if you drove 200km or 124 miles. That would make the total cost exactly $43. If Meghan plans on driving equal to or more than 200km then she should choose the $42.50 car. In my opinion the $19 should be enough for 1 day.

A perfect square is the product of any positive whole number used as a factor exactly two times. [Example: 49 is a perfect square because 7 × 7 = 49] The positive whole number N, when multiplied by 150, is a perfect square. What is the least possible positive whole number value for the number N?
A perfect square can be defined as a number that can be expressed as the product of an integer by itself or as the second exponent of an integer.
The value of N for the given question is 6.
To reach the above solution we need following steps:
Given:
[tex]\rm 150\times N = Perfect\:square[/tex]
Since 150 is not a perfect square N is not equals to 1.
Putting values starting from 2 on the place of N.
[tex]150\times2 = 300\\\\150 \times3=450\\\\150\times4= 600\\\\150\times5= 750\\\\150\times6=900[/tex]
Since 900 is a perfect square, the value of N will be 6.

A perfect square is the product of any positive whole number used as a factor exactly two times. The number six should be multiplied by the 150 to make it a perfect square. Thus least positive whole number which is multiplied by the 150 to make it a perfect square N is 30.
Given-
The given number in the problem which need to be perfect square is 150.
The least positive whole number which is multiplied by the 150 to make it a perfect square is N.
What is perfect square?A perfect square is the product of any positive whole number used as a factor exactly two times.
The number 150 needs to be break down in the small integers to get the value of the smallest integer which makes the product of integer and 150 a perfect square.
150 can be written as,
[tex]150=2\times3\times5\times5\\[/tex]
Two and three remains without the pairs. The product of 2 and 3 is 6.
Six should be multiplied by the 150 to make it a perfect square. Thus
