Add 4 kg 250 g, 2 kg 90 g and 19kg 3 g.
GarryVolchara [31]

Answer:

=25343 grams or 25 kg 343 g.

Step-by-step explanation:

1 kg = 1000 g

∴ 4 kg = 4000 grams

and the 4 kg 250 g would equal = 4250 grams.

∴ 2 kg = 1000 g

2 kg 90 g = 2000 grams + 90 g = 2090 grams

∴ 19 kg = 19000 grams

and 19 kg 3 grams = 19000 grams + 3 grams = 19003 grams

now we will add all of the values together to get the final answer.

4250 grams + 2090 grams + 19003 grams = 25343 grams or 25 kg 343 g.

Hope this helps!!

Okay here is another math problem I'll give a brainliest for the right answer!
Sliva [168]
To find the total area of this figure, you have to find the area of each of the separate figures and then add those 2 answers together. Your work should look like this:

2 x 2 = 4

8 x 8 = 64

64 + 4 = 68

Your answer should be 68 ft.^2

What is the relative maximum value of the function f(x) = –x3 + 6x2 – 9x – 1?
Vlad [161]

Answer:

-1.

Step-by-step explanation:

First find the derivative of f(x):

f'(x) = -3x^2 + 12x - 9 = 0   for a maximum or minimum.

-3(x^2 - 4x + 3) = 0

(x - 1)(x - 3) = 0

x = 1, 3.

To find which gives a relative maximum we find the second derivative:

f"(x) = -6x + 12

When x = 1  f"(x) = 6,    positive.

when x = 3, f"(x) = -6,  negative.

So x = 3 gives a maximum value of f(x).

f(3) = -(3)^3  + 6*(3)^2  - 9(3) - 1 = -1 (answer).

7.5A+4.75(500-A)=3351.25

7.5A+2375-4.75A=3351.25

2.75A=976.25

A=355 adults ($2662.50)

C=500-A=145 children ($688.75)
