Sum of odd numbers from 1 to 100?

Mathematics
1 answer:
Igoryamba3 years ago
4 0

Series would be: 1,3,5......99

Here, a=1, d = 3-1 = 2, l = 99

l = a+(n-1)d

99 = 1+(n-1)2

98 = 2n-2

2n = 100

n = 50

Sum would be Sn = n/2 (a+l)

 50/2 (1+99)

 25(100) = 2500

So, your answer is 2500

The price of the burritos and tacos, using the system of linear equations, is equal to $32 and $26, respectively.

It is given that for a recent company party, Carmen spent $58 on one plate of burritos and one plate of tacos. For a company meeting, she spent $90 on two plates of burritos and one plate of tacos. We need to find the cost of each dish.

Let the costs of burritos and tacos be represented by the variables "x" and "y", respectively. We can write two equations, as given below.

x + y = 58

2x + y = 90

We will substitute the value of "y" from the first equation into the second equation.

y = 58 - x

2x + y = 90

2x + 58 - x = 90

x = 90 - 58

x = 32

Hence, the price of the burritos is $32. Now, we will substitute this value into the first equation.

y = 58 - x

y = 58 - 32

y = 26

Hence, the price of the tacos is $26.

The complete question is given below.

Carmen often orders fiesta trays from her favorite Mexican restaurant for company events. For a recent company party, she spent $58 on 1 plate of burritos and 1 plate of tacos. For a company meeting, she spent $90 on 2 plates of burritos and 1 plate of tacos. How much does each type of dish cost?

A fishing lodge wants to build a new boat ramp. The slope of the ramp must be 8° to the horizontal. The total height of the bank
Likurg_2 [28]

Answer:

The length of the sloping section of the ramp is 20.12 m

Step-by-step explanation:

Given;

the total height of the bank, h = 2.8 m

The slope of the ramp must be 8° to the horizontal, i.e, θ = 8°

Let the length of the sloping section = L

let the horizontal distance between the height of the bank and sloping section = b

Thus, h, L and b forms three sides of a right angled-triangle, with L as the hypotenuse side, h  (height of the triangle) as the opposite side and b  (base of the triangle) as the adjacent side.

We determine L by applying the following formula;

Sinθ = opposite / hypotenuse

Sin θ = h / L

L = h / Sin θ

L = 2.8 / Sin 8

L = 2.8 / 0.13917

L = 20.12 m

Therefore, the length of the sloping section of the ramp is 20.12 m

It will still be 6 units high. Even if the width is reduced, that does not effect the height of  the farm.
