Without calculating, explain how many decimal places are in the product 0.6 X0.4 X 1.9. Rewrite the expression as the product of two decimals to support your answer.

Answers

Answer 1

There's only one decimal point in the answer. This is quite obvious. Regardless of whether or not your adding, subtracting, dividing, or multiplying, there's really only going to be one decimal, ever. This doesn't change, However, what DOES change are decimal PLACES.

Looking at the problem, you see both .6 and .4 are placed to the right of the decimal, otherwise known as the tenths place (1/10).

Looking at 1.9, you see you have one number (1) placed to the left of the decimal, the ones place, and another number placed to the right of the decimal (9), in the tenths place.

Well, this is simple. You can look and see that your multiplying fractions against a whole number, which will of course make this whole number even smaller. By how much though??

Well, you can really tell this by looking at how MANY numbers are behind the decimal. You have .9, .4, and .6

That's 3 numbers behind the decimal place. This may not help you solve the problem itself, but this tells you here (ignoring the 1, that will be taken out immediately while solving and turned into a 0) that you will have 3 numbers placed from the tenths place all the way to the thousandths place.

Basically, this tells you that you'll have three decimal places to the right of the decimal.

As for rewriting your problem to better show this, that's simple too.

All you have to do is simple multiplication, just in the tenths place. How? You know that 6*4 (referring to .6 and .4) is 24, that means that .6*.4 will be .24

How does this support your answer before? .24 has TWO numbers to the right of the decimal. That's TWO decimal places. With the .9 in 1.9, that's still THREE decimal places to the right of the decimal, and your answer would be the same.

So, here's it re-written.
1.9*.24=X

~Hope this helps!

Answer 2

Final answer:

The product 0.6 x 0.4 x 1.9 has three decimal places.

Explanation:

To determine the number of decimal places in the product 0.6 x 0.4 x 1.9, we can rewrite each decimal as the product of two decimals and count the total number of decimal places.

0.6 can be written as 0.6 x 1.0, which has one decimal place.

0.4 can be written as 0.4 x 1.0, which also has one decimal place.

1.9 can be written as 1.9 x 1.0, which has one decimal place.

Since each decimal has one decimal place, the product 0.6 x 0.4 x 1.9 has a total of three decimal places.

Which counterexample shows that the conjecture "All animals that can fly are birds" is false?

Answers

It seems like you forgot to post the answer choices. However, bats are one animal where they can fly but they aren't birds. So this is one counter-example to prove the claim false. Another example would be any flying insects.

B would be incorrect as it is not a counterexample to the claim. C would be incorrect as a chipmunk is not a bird. And D would be incorrect as the claim says "All animals that can fly are birds" it doesn't say "every bird" or "all birds can fly"
So A is the logical choice and according to what Jimthompson5910 said "bats are one animal where they can fly but they aren't birds."

The verticals of a parallelogram are G(-8,3), R(-7,6),A(-3,6), and M(-4,3). Graph GRAM and G’R’A’M’, it’s image after a translation 13 units right and 2 units up

Answers

See the attached diagram for a plot of the original vertices and their images.

The image of parallelogram GRAM, G'R'A'M', after a translation 13 units right and 2 units up is formed by the points G'(5, 5), R'(6, 8), A'(10, 8), and M'(9, 5).

To graph the parallelogram GRAM and its image G'R'A'M' after a translation 13 units right and 2 units up, follow these steps:

Plot the points G(-8,3), R(-7,6), A(-3,6), and M(-4,3) to form the parallelogram GRAM.

Calculate the new coordinates for G', R', A', and M' after the translation. You'll add 13 units to the x-coordinates (rightward) and 2 units to the y-coordinates (upward):

G'(-8 + 13, 3 + 2) = G'(5, 5)

R'(-7 + 13, 6 + 2) = R'(6, 8)

A'(-3 + 13, 6 + 2) = A'(10, 8)

M'(-4 + 13, 3 + 2) = M'(9, 5)

Plot the new points G'(5, 5), R'(6, 8), A'(10, 8), and M'(9, 5) to form the parallelogram G'R'A'M'. These points will be the image after the translation.

The perimeter of a pentagon is 20t+7. Four sides have the following lengths: 6t, 2t, 4t-5, and 5t+1.What is the length of the fifth side?

Answers

The length of the fifth side is -59/3 units.

How to calculate the length?

The perimeter of a pentagon is the sum of the lengths of all five sides.

We know that the four sides have lengths of 6t, 2t, 4t-5, and 5t+1. Let's add these together:

6t + 2t + (4t-5) + (5t+1) = 17t - 4

We also know that the perimeter is equal to 20t+7. So we can set these two expressions equal to each other and solve for the fifth side:

17t - 4 = 20t + 7

Subtracting 17t from both sides, we get:

-4 = 3t + 7

Subtracting 7 from both sides, we get:

-11 = 3t

Dividing both sides by 3, we get:

-11/3 = t

Now that we know the value of t, we can find the length of the fifth side by substituting t back into one of the expressions for the sides. Let's use the expression for the third side, which is 4t-5:

4t - 5 = 4(-11/3) - 5 = -44/3 - 15/3 = -59/3

So the length of the fifth side is -59/3 units.

The length of a rectangle is 4 times its width. The area of the rectangle is 144 square inches. Find the dimensions of the rectangle

Answers

4w=l
4w*w=144
4w^2=144
w^2=38
w=6.16
l=4*6.16=24.63
(*there might be small rounding errors)
and they are both in inches

The width is 6 inches and the length is 24 inches.

To find the dimensions of the rectangle when given the area and the relationship between length and width, we will use algebra. Let the width be w inches. The length is 4 times the width, so the length is 4w inches. The area of the rectangle is w times the length (4w), which gives us w * 4w = 144 square inches. Simplifying, this equation becomes 4w^2 = 144 inches2. To find w, we divide both sides by 4, getting w^2 = 36. Taking the square root of 36 gives us w = 6 inches. Since the length is four times the width, the length is 24 inches. Therefore, the dimensions of the rectangle are 6 inches by 24 inches.

We need to find the slope.

What is the slope?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of a line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.

Now, slope=rise/run

To answer this question you will use the formula for finding volume of a rectangular prism. V=lwh, where V stands for volume, l stands for the length, w stands for the width, and h stands for the height. What you are really doing is finding the area of the base of the rectangular prism by multiplying the length by the width. Once you have this you then multiply it by the height which takes you all the way through the prism to create the third dimension of volume. The answer is 63,945 cubic inches.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

The marked price of bicycle = $500

Discount percentage = 30% = 0.30

Now, discount price = 500(0.30)

⇒ $150

The sale price of the bicycle can be found as

Sale price = Marked price - discount price

⇒ Sale price = 500 - 150

⇒ Sale price = $350

Hence we can conclude that the sale price of the bicycle in a store is $350.

Answers

You bought 6 packages of hot dogs.

To solve this, you have to write and solve a system of equations. Let B stand for hamburgers and H stand for hot dogs.

B + H = 11
8B + 2H = 52 If you multiply the top equation by -2, you can solve by eliminatoin.

-2B + -2H = -22
8B + 2H = 52 Add the equations

6B = 30
B = 5

If you bought 5 packages of hamburgers, then you bought 6 packages of hot doges. 11 - 5 = 6
