Multiply it by 1000 and do it to the rest

The page gives you the information that 1 kg is equal to 1000 grams.
This means that you just need to multiply each kg by 1000.

e.g. 6.8 * 1000 = 6800

Hope this helps!

Scott used 1 3 tablespoons of salt to make 1 4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he
olasank [31]

Answer:

B) 4 tablespoons of salt

Step-by-step explanation:

Here is the correct question: Scott used 1/3 tablespoons of salt to make 1/4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he need to make triple the recipe?

Given is the ratio of salt and beans to make recipe for 1 liter of beans.

Ratio given for 1 liters of beans; \frac{salt}{beans} = \frac{\frac{1}{3} }{\frac{1}{4} }.

Now, simplifying the ratio

\frac{\frac{1}{3} }{\frac{1}{4} }= \frac{1}{3} \times \frac{4}{1}

∴ Ratio for salt and bean in a recipe for 1 liter of beans is \frac{4}{3}.

Next, finding the proportion of salt to make triple the recipe.

Triple the recipe means 3 times of 1 liter of beans, which is 3 liters of beans.

∴ The proportion of salt in 3 liter beans= \frac{4\ tablespoon\ salt}{3\ tablespoon\ beans} \times 3\ lts\ of\ beans

Hence, 4 tablespoon of salt is required to make 3 liters of beans or triple the recipe.

(1 point) Carbon dating is often used to determine the age of a fossil. For example, a humanoid skull was found in a cave in Sou
Aleksandr [31]

Answer:

The estimated age of the skull is 39118 years.

Step-by-step explanation:

The amount of the substance after t years is given by:

A(t) = A(0)(1-r)^t

In which A(0) is the initial amount, and r is the decay rate.

The half-life of carbon-14 is about 5600 years.

This means that A(5600) = 0.5A(0). We use this to find r, or 1 - r, to replace in the equation. So

A(t) = A(0)(1-r)^t

0.5A(0) = A(0)(1-r)^{5600}

(1-r)^{5600} = 0.5

\sqrt[5600]{(1-r)^{5600}} = \sqrt[5600]{0.5}

1 - r = (0.5)^{\frac{1}{5600}}

1 - r = 0.9999

So

A(t) = A(0)(0.9999)^t

Only 2% of the original amount of carbon-14 remains in the burnt wood of the campfire.

This is t for which A(t) = 0.02A(0). So

A(t) = A(0)(0.9999)^t

0.02A(0) = A(0)(0.9999)^t

(0.9999)^t = 0.02

\log{(0.9999)^t} = \log{0.02}

t\log{0.9999} = \log{0.02}

t = \frac{\log{0.02}}{\log{0.9999}}

t = 39118

The estimated age of the skull is 39118 years.

Find the slope of the line<br><br>-4<br>-1/4<br>1/4<br>4
viva [34]
Find 2 "easy" points on the graph, and identify their coordinates.  One such point would be (-4,1) and another would be (4,2).

run = 8 (from -4 to +4)
rise = 2 (from 0 to 2)

              rise           2
slope = ------- = -------- = 1/4                   y-intercept is (0,1)
               run          8

equation of this line is   thus   y = mx + b, or   y = (1/4)x + 1  (answer)

Jack scored a mean of 15 points per game in his first 3 basketball games. In his 4th game, he scored 27 points. What is his mean
timurjin [86]

His mean score for the first 4 games will be 18 points.

Explanation

In the first 3 games, the mean of the scores is 15 points . Mean is the simple average of some numbers.

So, the total score in first 3 games = (15*3)= 45 points

Now, in the 4th game, he scored 27 points. So, the total score in the first 4 games = 45+27= 72 points

Thus, the average of scores in first 4 games = \frac{72}{4} = 18 points

So, his mean score for the first 4 games will be 18 points.

#1 second line: x-y=-3
x=y-3(isolating x to prepare for substitution)(what x is equivalent to)
get back to the first line
x+y=5
(y-3)+y=5(substituting the value of x of the first line with the value of x at the second line)(It is a process to find the intersection between the two lines(line#1 and line#2 are two linear functions)
2y-3=5(simplify)
2y=8(simplify)
y=4(simplify)
line#1 x+y=5
x+(4)=5(plug the value of y back into either line#1 or line#2 will work)(plugging in the y value of the point of intersection to solve for the x value of the point of intersection)
x=1(solve)
the two linear lines intersect at the point(1(x coordinate), 4(y coordinate))(1,4)
 
#2 (line#1) y=3x-1
     (line#2) 2x+y=14
2x+(3x-1)=14
5x-1=14
5x=15
x=3

#3 line#1 2x+3y=8
     line#2 6x+9y=24
2x=8-3y
x=(8-3y)/2
6((8-3y)/2)+9y=24
24-9y+9y=24
24=24
(those two lines are on top of yeach other/the same line)
any point on the line

#4 line#1 3x-4y=12
     line#2 y=3/4x-4
3x-4(3/4x-4)=12
3x-3x+16=12
16=12
parallel lines: lines with same slope and different y-intercept
No solution/they never intercept each other
