Jen solved this math sentence: 9 X 0.989 = 89.01. How can you use estimation to show that

vampirchik [111]

Answer:

She put decimal in the wrong place.

Step-by-step explanation:

Consider the provided sentence.

9 × 0.989 = 89.01

Estimate the number 0.989 to nearest natural number.

The estimation of the number 0.989 to the nearest natural number is 1.

Now multiply 9 with 1.

9 × 1 = 9

Hence, the product should be less than 9.

Since the product of 9 and 0.989 is 89.01 which is greater than 9.

Thus, we can concluded that Jen's answer is wrong.

She put decimal in the wrong place, the required product must be 8.901

Here, you can observe that the number 8.901 is less than 9 and estimation of the number to the nearest natural number is 9.

Janice wants to create a test containing 20 questions worth 50 points. If Janice creates questions worth either two points or fo

Elena L [17]

Answer:

15 two-point questions and 5 four-point questions.

Step-by-step explanation:

Let x represent number of two-points questions and y represent number of four-points questions.

We have been given that Janice wants to create a test containing 20 questions. We can represent this information in an equation as:

$x+y=20...(1)$

Since all questions are worth 50 points. We can represent this information in an equation as:

$2x+4y=50...(2)$

From equation (1), we will get:

$x=20-y$

Upon substituting this value in equation (2), we will get:

$2(20-y)+4y=50$

$40-2y+4y=50$

$40+2y=50$

$40-40+2y=50-40$

$2y=10$

$\frac{2y}{2}=\frac{10}{2}$

$y=5$

Therefore, there are 5 questions that are worth 4 points each.

Now, we will substitute $y=5$ in equation (1) to solve for x.

$x+5=20$

$x+5-5=20-5$

$x=15$

Therefore, there are 15 questions that are worth 2 points each.
