Step-by-step explanation:
Given the sequence
1, 3, 6, 10, 15
(a)
This is the sequence of triangular numbers.
After the first term the pattern is
+ 2, + 3, + 4, + 5, ............
(b)
Using this pattern then
a₆ = a₅ + 6 = 15 + 6 = 21
a₇ = a₆ + 7 = 21 + 7 = 28
a₈ = a₇ + 8 = 28 + 8 = 36
(c)
The n th term formula for triangular numbers is
[tex]a_{n}[/tex] = [tex]\frac{1}{2}[/tex] n(n + 1)
(d)
Substitute n = 21 into the formula
a₂₁ = [tex]\frac{1}{2}[/tex] × 21 × 22 = 21 × 11 = 231
Find the value of 8.6 + 9.7.

Tick the correct answer and justify : In Δ ABC, AB = 6 3 cm, AC = 12 cm and BC = 6 cm. The angle B is : (A) 120° (B) 60° (C) 90° (D) 45°
Answer:
(C) 90°
Step-by-step explanation:
The computation of the angle b is as followS:
Given that,
AB = 6√3 cm,
AC = 12 cm,
And BC = 6 cm
Now squaring all the above ones
AB^2 = 108
AC^2 = 144
And, BC62 = 36
AB^2 + BC^2 = AC^2
It shows the Pythagoras theorem.
Therefore the angle B is a right triangle i.e. 90 degrees
Hence, the correct option is C.

John was asked to stock the store shelves with boxes of cereal there were 12 empty shelves that can hold eight boxes of cereal each if there were 85 boxes of cereal in the back of John store how many shelves could John completely filled with cereal boxes
Answer:
10 shelves
Step-by-step explanation:
In order to calculate how many whole shelves we can fill we simply need to divide the total number of cereal boxes that John has in the back by the number of boxes that each shelf can hold like so...
85 / 8 = 10.625
Based on these numbers we can see that with the number of cereal boxes available we can fill a total of 10 shelves by using
10 * 8 = 80 cereal boxes
80 cereal boxes. That would leave 5 cereal boxes left which is not enough to fill another shelve.
The length of a rectangle is twice its width. The perimeter is 60 ft. Find its area.
A = 200 ft ²
A = 10 ft ²
A = 100 ft ²
Answer:
200ft^2
Step-by-step explanation:
From the first sentence;
L = 2B
Perimeter of a rectangle = 60ft
P = 2[ L +B ]
substitute as follows;
60 = 2( 2B + B)
60 = 2(3B)
60 = 6B
B = 10ft
To find L
L = 2B
L = 2*10
L = 20 ft
Area of a rectangle = LB
= 20×10
=200ft^2

Can someone find the surface area for me?
9514 1404 393
Answer:
876 square inches
Step-by-step explanation:
The total surface area is the sum of the areas of the two triangular bases, and the lateral area--the sum of the areas of the three rectangular faces.
Total triangle area:
2(1/2)(bh) = bh = (26 in)(6 in) = 156 in²
Rectangular face area is the product of the length of the prism (12 in) and the perimeter of the base:
(12 in)(26 in + 24 in + 10 in) = (12 in)(60 in) = 720 in²
Total area is then ...
base area + lateral area = 156 in² +720 in² = 876 in²

Comment on the question
The geometry shown is impossible. The base width must be about 31.24 inches for the other dimensions to be accurate.
A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the given equation. Using this equation find out the maximum amount of profit the company can make to the nearest dollar. Y=-x^2+64x-292
Answer:
The maximum amount of profit is 32
Step-by-step explanation:
Given
[tex]y=-x^2+64x-292[/tex]
Required
Determine the maximum profit
This is calculated by calculating the maximum of the function.
A quadratic function is of the form
[tex]y = ax^2 + bx + c[/tex]
and its maximum is:
[tex]Max = \frac{-b}{2a}[/tex]
So: [tex]y=-x^2+64x-292[/tex]
We have that
[tex]a = -1[/tex]
[tex]b = 64[/tex]
[tex]c = -292[/tex]
[tex]Max = \frac{-b}{2a}[/tex]
[tex]Max = \frac{-64}{2 * -1}[/tex]
[tex]Max = \frac{-64}{-2}[/tex]
[tex]Max = 32[/tex]
Hence, the maximum amount of profit is 32
Answer:
732
Step-by-step explanation:
Formula: -b/2a
-64/2(-1)
-64/-2= 32
Then you substitute x for your answer
-(32)^2+64(32)-292
-1024+2048-292= 732
You can also go on demos and type in the equation. The answer will be the Y value on the vertex (top of the parabola)
