what is
7 less than the product of 30 and a number r

Answers

Step-by-step explanation:

Take your clues from the question itself.

"5 less than," tells you that you're going to have "minus 5" AFTER something else.

"Product" always means multiplication. "Unknown number" is your variable. (Usually x or n.) So "the product of 7 and an unknown number" means "7 times x." Or just "7x."

And of course, you know what "is equal to 42" means. ;-)

Now put it all together.

I know that my "minus 5" has to go second. And I know that my "is equal to" has to go last. So the "product" part has to go first.

The product of 7 and a number minus 5 is equal to 42.

7x - 5 = 42

I hope that helps!

A figure shows a triangle drawn inside a square. The area of the triangle is 40 cm², and the area of the square is 64 cm². A point on the figure is randomly selected, and its location is recorded.

After 150 trials, the randomly selected point was in the triangle 105 times.

How does the experimental probability of a randomly selected point being in the triangle compare to the theoretical probability of the event?

The experimental probability of the event is
Choose...
and the theoretical probability of the event is
Choose...
. Therefore, the experimental probability is
Choose...
the theoretical probability.

Answers

Answer:

1) 70%

2) 62.5

3) GREATER THAN

Step-by-step explanation:

I TOOK THE QUIZ TOO I KNOW ITS RIGHT

The theoretical probability is less likely than the experimental probability.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The experimental probability of a randomly selected point being in the triangle is found by dividing the number of times the point was in the triangle by the total number of trials. In this case, the experimental probability is:

Experimental probability = Number of times point was in triangle / Total number of trials

Experimental probability = 105 / 150

Experimental probability = 0.7

To find the theoretical probability, we need to divide the area of the triangle by the area of the square, since the point could be selected from anywhere in the square. In this case, the theoretical probability is:

Theoretical probability = Area of triangle / Area of square

Theoretical probability = 40 cm² / 64 cm²

Theoretical probability = 0.625

Comparing the experimental probability and the theoretical probability, we can see that:

Experimental probability = 0.7

Theoretical probability = 0.625

Therefore, the experimental probability is greater than the theoretical probability.

Step by step:
1/2y + 1/4 = 1/12(3+xy)
6y + 3 = 3 + xy

how the flibberdoodle do you graph decimals on a coordinate graph?!!

Answers

Plotting coordinates can be a little confusing, but it doesn't have to be as long as you remember a few important details. The first number in the coordinate set tells you how far right (for a positive number) or left (for a negative number) you need to travel on the x-axis. The second number in the coordinate set tells you how far up (for a positive number) or down (for a negative number) you need to travel on the y-axis. Any set of coordinates can be represented by the variables x and y. If you picture (x, y), it will help you remember the x-coordinate comes first, so you will travel either right or left before travelling up or down.

Answer:

When graphing decimals it is good to remember that a decimal is just part of a whole number. For example, 0.5 is half of 1. Therefore, if you were to plot 0.5 you would draw a dot in between 0 and 1.

How many triangles can be formed with segments measuring 4.7 m, 1.6 m, and 2.9 m?

none

one

more than one

Answers

Answer:

  (a)  none

Step-by-step explanation:

You want to know how many triangles can be formed from segments of lengths 1.6 m, 2.9 m, and 4.7 m.

Triangle inequality

The triangle inequality requires the sum of the two shorter segments exceed the length of the longest one.

  1.6 + 2.9 > 4.7

  4.5 > 4.7 . . . . . . . not true — no triangle can be formed

These segments will form no triangles.

Tia's teacher asked her to find the product of 8 and 207 in her head. Which of the following describes the best way for Tia to mentally calculate the answer?

Answers

Answer:

1656

Step-by-step explanation:

200 = 200 + 7

So,

8 * 207

= 8 * (200 + 7)

= (8*200) + (8*7)

= 1600 + 56

= 1656

=》To do it mentally, Tia has to first seperate 207 as 200 + 7 & multiply 8 with 200 & 7 & then add the products. The answer is 1656.

Hope it helps ⚜

The product of 8 and 207 is 1656. This method allows Tia to simplify the mental calculation by breaking it into smaller, more manageable steps.

The best way for Tia to mentally calculate the product of 8 and 207 is to use the distributive property and break down the multiplication into as:

Recognize that 207 can be broken down as 200 + 7.

Now, calculate the product of 8 and 200 as:

8 × 200 = 1600                        (1)

Calculate the product of 8 and 7 as:

8 × 7 = 56                                 (2)

Add the results from equation (1) and (2),

1600 + 56 = 1656.

So, the product of 8 and 207 is 1656.
