Answer:

5 kg 800 grams

5800g

Step-by-step explanation:

the first step is to convert 1kg to gram

100 kilogram = 1 gram

1kg x 1000 = 1000g

1kg 160 gram = 1000 + 160 = 1160 gram

If 1 sack weighs 1160 g

5 sacks = 1160g x 5 = 5800 gram

or 5800 / 1000 = 5 kg 800 grams

Step-by-step explanation:

Answer:

Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:

P is the price of the cake

S is the number of servings

Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)

In turn, 10 is the fixed cost of each cake.

Answer:

34%

Step-by-step explanation:

Answer:

A) 34%

Step-by-step explanation:

Lets say that the price of this object was $100.

Then, we know that each week the price is reducing by 10%, so therefore, we take 10% of $100, and we have $10

If we subtract that from $100, ($100-$10), we find that the price has come down to $90 after the first reduction in the first week. We will now do this process three more times to get to the four weeks total.

10% of $90 dollars is 9 dollars, so therefore the price reduces to $90-$9, $81 after the second reduction in the second week.

Then we take 10% of $81 and then get $8.1. We subtract that from $81 and get  $72.9

Then for the final reduction in the fourth week, we take 10% of $72.9, and we get $7.29. Take that from $72.9, and you get $65.61, which we can round to $66.

The question however asks how much was the approximate percantage in decresse over the 4 weeks. We see that the object went from $100 to $66, which is $34 decrease.

Now we simply find what percantage of $100 is $34, and that is 34%, which gives you option A.

Hope this helped.

Answer:

y = -1

Step-by-step explanation:

I'll solve for "y" since there is no "x"

First expand the numbers inside the parenthesis by multiplying -4

-4y  + 8 =12

Subtract 8 from both sides to isolate -4y

-4y = 4

divide both sides by -4 to get "y"

y= -1

Answer:

Photosynthesis is

Step-by-step explanation:

The process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Hope this answered your question :)

Answer:

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:

B. The graph curves away from its sum

Step-by-step explanation:

A convergent infinite geometric series, the graph of the series curves away from the sum, the correct option is B.

A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.

The standard equation for geometric series is

Tₙ = a₁ rⁿ⁻¹

The sum of an infinite geometric series is given by

S = a₁/(1-r)

where a₁ is the first term and r is the common ratio.

The graph of an infinite series curves away from its sum.

Answer:

3x+10 = 100

or

100 - 10 = 3x

Answer:

A

Step-by-step explanation:

The linear equation in two variables is given to us is

→ y = 3( x -4) +6x

Slope Intercept Form :-

→ y = 3x - 12 + 6x

→ y = 6x + 3x -12

→ y = 9x - 12

Answer:

804.2

Step-by-step explanation:

what ? you cannot use a calculator ? it is all there, you only need to type it in.

the only point, where you need to "think" is the difference between radius and diameter. because the graphic gave you the diameter, and the formula asks for the radius.

so ... ... ... ... did you figure it out ?

the radius is half of the diameter, so, 8ft in this example.

S.A. stands for "Surface Area".

so, now, again, we only need to type it into the calculator.

[tex]4 \times \pi \times {8}^{2} [/tex]

[tex]4 \times \pi \times 8 \times 8[/tex]

[tex]4 \times \pi \times 64[/tex]

and the result 804.2477...

rounding it to the nearest tenth (you know, the first position after the comma) is then 804.2

you really needed help with that one ?

Answer:

D) 100% Positve

Step-by-step explanation:

You would choose the second option (y=1/3x) because the slope would be 1/3. Think of the slope as your directions, you go up 1 over to the right 3 times. Since the y-intercept is 0, you don't have to add anything at the end.

2/5, 0.4, 40%

7/10, 0.7, 70%

1/2, 0.5, 50%

1/2, 0.5, 50%

4/5, 0.8, 80%

3/5, 0.6, 60%

3/10, 0.3 ; 30%

Step-by-step explanation:

Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

P(less Than 5) :

Required = (1, 2, 3, 4) = 4 observations

P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%

Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations

P greater Than 3) = 7/10 = 0.7 = 70%

Odd = (1,3,5,7,9) = 5

P(odd) = 5 / 10 = 1/2 = 0.5 = 50%

(even) = (2,4,6,8,10) = 5

P(even) = 5 / 10 = 1/2 = 0.5 = 50%

Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8

P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%

not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6

P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%

Divisible by 3 = (3, 6, 9) = 3

P(divisible by 3). = 3/10 = 0.3 = 30%

Answer:

blue line : y = 3

black horizontal line : y = 0

black vertical line : x = 0

Step-by-step explanation:

it is really simple.

blue line : no matter what value we pick for x, the functional value for y is always 3. and that defines the equation y = 3 + 0*x or simply y = 3.

the same with the black horizontal line. the difference is that y is now always 0. so, y = 0.
