$ 0.79 x 3.7

1 answer:

6 0

$0.79
x 3.7
---------
553
+2370
---------
2.923----> move the decimal three times to the left because that is how many spaces you have to the right on the actual equation until the next decimal.

The product of 0.79x 3.7 is 2.923. And, the decimal was moved three times to the right of the equation because of the number of spaces until the next decimal which then allows you to move the decimal three times to the left on the product.

I need help on this and the first person who answer correctly gets a BRANILIST

True [87]

Answer:

first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml

Answer:

4 hours

Step-by-step explanation:

I found the average

(3+5)/2

8/2 = 4

This is probably wrong because logically it wouldn't make sense for them to take longer than 3 hours if two people are cleaning but i dont know

On our first quiz Juan scored 82. Use a compound inequality to show the possible score x he got on his second test, if the avera

bogdanovich [222]

We determine the minimum and maximum scores that Juan needs to get in order to be within the strict average range. We let x be his score.

minimum:
74 = (82 + x) / 2
The value of x from the equation is equal to 66.

maximum:
80 = (82 + x )/2
The value of x from the equation is equal to 78.

Hence, Juan's score should fall between 66 and 78, inclusive.

Answer:  66 ≤ x ≤ 78

Determine whether each table below models a linear, quadratic or exponential function.

Virty [35]

The correct answers are:

The first table is linear.
The second table is exponential.

Explanation:

To see if a set of data is linear, we find the slope. Slope is given by the formula

$m=\frac{y_2-y_1}{x_2-x_1}$ .

We check each pair of points in the first table. The slope between the first two points is:
$m=\frac{1-4}{6-5}=\frac{-3}{1}=-3.$

The slope between the second two points is:
$m=\frac{-2-1}{7-6}=\frac{-3}{1}=-3$

The slope between the third two points is:
$m=\frac{-5--2}{8-7}=\frac{-5+2}{8-7}=\frac{-3}{1}=-3$

Since the slope is the same between any two pairs of points, this is a linear set of data.

Checking each pair of points in the second table, we have:
$m=\frac{1-0}{6-5}=\frac{1}{1}=1$ for the first two points.

For the second pair of points, we have:
$m=\frac{4-1}{7-6}=\frac{3}{1}=3$

Since the slope is not the same between each pair of points, we know the data is not linear.

Next we will check the second table to see if it is quadratic. Since the x-coordinates go up the same number each time, we can check the y-coordinates, specifically looking at the second differences.

For the second differences, we first find the difference between each y-value:
1-0=1
4-1=3
8-4=4

Now we find the difference between each first difference:
3-1=2
4-3=1

Since these second differences are not the same, the data is not quadratic.

From graphing the data in the table, we can see that the data in the second table is exponential.
