A recipe for 1.5 batches of cookies uses 2 cups of sugar. How much sugar is used for each batch?

Answers

Answer:

1.3 cups

Step-by-step explanation:

Divide the 2 cups of sugar by 1.5

Take the 2 cups of sugar and divide it by 3, then multiply that number by 2

Rounding to the nearest hundredth, each batch uses about 1.33 cups of sugar.

What is division?

Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.

To find out how much sugar is used for each batch, we need to divide the total amount of sugar used for 1.5 batches by 1.5.

If 1.5 batches use 2 cups of sugar, then 1 batch will use:

2 cups ÷ 1.5 = 1.333... cups

Rounding to the nearest hundredth, we can say that each batch uses about 1.33 cups of sugar.

A stack of nickels has a mass of 45g. There are 9 nickels in the stack. What is the mass of one nickel?

Answers

The answer is 5g!!!!

5 grams

Step-by-step explanation:

Given Information :

Mass of a stack of nickels = 45g

No of nickels in a stack = 9 nickels

Mass of one nickel = ?

Let the mass of one nickel be x

[tex]9 \: nickels = 45g \\ 1 \: nickels = xg[/tex]

Cross Multiply

[tex]9x = 45[/tex]

Divide both sides of the equation by 9

how do the equations y = mx and y =kx compare plz help me bad answers will be reported

Answers

We can compare y = kx to the slope-intercept form of a line, y = mx + b.

We can see that y = kx is a linear equation with slope k and y-intercept 0.

Hey there!

The difference is that y = kx means the "y directly varies with x", which means that y/x = k. Also, the line of the graph passes directly through the origin. Or, in other words, there is no y - intercept other than (0, 0)

y = mx could have a y - intercept not at the origin. If you have an equation in slope - intercept form, such as y = 5x + 3, than "y" does not directly vary with "x", because you can't get "m" by doing y/x, because first you have to subtract 3. In order to actually find "m", you would have to do (y - 3) / x = m (or, in this case, 5).

Hope this helps! Good luck and have a great day!

triangle abc and dgf are similar the lengths of two corresponding sides are 1.4 m and 56 cm what is the ratio of the perimeters of these triangles?

Answers

The answer would be 1.8

The answer is 5/2 in fraction form or 2.5 in decimal form.

1.4 meters is equal to 140 centimeters. We can find the ratio with just these two side lengths because we know that the shapes are similar, so the other corresponding sides will also have the same ratio.

Then, we can take 140 and divide it by 56 which, simplified, gives us the fraction 5/2. Because of the Fundamental Theorem of Similarity, you keep the fraction the way it is. (If you are finding the ratio of areas or surface areas, you square the fraction, and if you are finding the ratio of the volumes you cube it.)

I going to say its going to take her about 15 months to invest in the money to get the iPhone. But if you still don't get it, just take a look at my math.

Jenna wants to save => $35/per month

$35 * 14 mo = $490 + $20 = $510

(The $20 is for what Jenna started with, she most likely saved that up too)

So, it will take her about 15 months to get an iPhone.
