An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms.
¾ of this weight is metal, and the rest is wood.


How much does the wood part of the sculpture weigh?

Answers

Answer:

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Step-by-step explanation:

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight =

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

I think you would have to convert 14.9 kg to fraction and multiply by 3/4 try it

To make orange fizz, Noah mixes 4 scoops of powder with 6 cups of water. Andre mixes 5 scoops of powder with cups of water. Create a double number line or a table that shows different amounts of powder and water that taste the same as Noah’s mixture.

Answers

Answer:

Noah mixes 4 scoops of powder with 6 cups of water.

Means Noah ratio will be  or 0.67

Andre mixes 5 scoops of powder with 8 cups of water

Means Andre ratio will be  or 0.62

As, or 0.66 > 0.62

We can say that content of orange powder will be more in Noah mixture than in Andre's Mixture.

Hence, Noah's mixture will taste more like orange, than Andre's mixture.

Answers

Answer: y= -8/4x+2

Step-by-step explanation:

find our y-intercept and slope

(rise over run to find your slope)

the two points it provides are what you will use to find the slope

see how for you run from point A to B then your rise as well

it should be rise=-8 run=4

0,2 is your y-intercept

now use your equation y= mx+b

b=your y-intercept and mx= your slope

2x - 8x + 1 = 49
this seriously makes no sense

Answers

Answer:

x = -8

Step-by-step explanation:

2x - 8x + 1 = 49

⇒ 2x - 8x = 49 - 1

⇒ -6x = 48

⇒ x = [tex]\frac{48}{-6}[/tex]

       = -8

Answer:

X = -8

Step-by-step explanation:

Add similar elements: 2x-8=6x

-6x+1=49

Subtract 1 from both sides:

-6x+1 -1 =49 - 1

Simplify:

-6x=48

Divide both sides by -6

-6x /-6= 48 /6

Which then gets you the answer up top!

Answers

I think the slope is 3/2

Answer:

The slope of this line is 5/3. Or, 1 2/3. The equation would be y = 5/3x

Step-by-step explanation:

You are in luck my friend!

To find the slope of a line on a graph, you need to find the rise over run. You need to pick two definite points on a graph. An intersection whereyou can clearly tell the value. For example 1,1 and -4,-4. Then use your finger and trace how many units up you have to go, and then how many units across. (This is a very common topic so if you need further help just look up rise over run. This fact will put you ahead, do you see how the line intersects between the 2 and the 3 in the y axis? This is called the y intersect, you will see it added to the slope so if the equation is y = 5/3x it would be written as y = 5/3x + 2.5 because that is where the line intersects with the y axis.) Back to slope, remember that the formula is always rise/run. Later, you will find to points and use a slope formula. y2-y1/x2-x1.
