How do you Estimate the Product of Decimals and Whole
Numbers
Estimate each product. You can round to the greatest position or
use compatible numbers. Show how you estimated.
Answer:
1) 8.5
2) 60
3) 69.3
4) 6.8
5) 3.6
6) 10.5
Step-by-step explanation:
Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 or 276)

What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the instructions provided in the question,
Dessie can type twice as compared to Jasmine per minute.
Let's assume that Jasmine can type x words per minute.
Then,
Twice Jasmine will be equal to 2x.
Then, the words typed by Dessie will be 2x per minute.

Answer:
y=-2x+2
Step-by-step explanation:
the slope intercept form is y=mx+b
slope - to find the slope from 2 point you do (y2-y1)/(x2-x1) so it would be
(14-2)/(-6-0). which out simplify to -2.
y-intercept - the y-intercept is given in one of the points (0,2).

If a car travels 180 miles in 4 hours, how many miles would it go in 6?
Answer:
270
Step-by-step explanation:
First, to find how far the car will go in one hour, you do 180 divided by 4. We already know that the car drives at a constant rate. If you do 180 divided by 4, you get 45. Then you multiply 45 by the amount of hours (6) to get 270

Find the slope of a line that passes through the points (-5, 3) and (-3, 8)
Answer:
Slope: 5/2 or 2.5
Step-by-step explanation:
1. Put both of the y values together on the top of a fraction and the x values on the bottom.
It should look like this: [tex]\frac{8-3}{-3-(-5)}[/tex]
2. Now you need to simplify the y and x values. -3-(-5) is equal to 2 and 8-3 is 5.
I should now look like this: [tex]\frac{5}{2}[/tex]
3. That could be your answer as a fraction. Or you can take the extra step and actually divide them. 5 divided by 2 is 2.5.
In the end, you will have a result of 5/2 or 2.5. That it the slope of the line of the points (-5,3) and (-3,8). I hope this helps and you actually understand it. Remember, don't cheat! Always do your best! Good luck!
The given points are:
[tex](x_1, y_1) = (-5, 3)[/tex][tex](x_2, y_2) = (-3, 8)[/tex]As we know,
Slope, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
[tex]= \frac{8-3}{-3-(-5)}[/tex]
[tex]= \frac{5}{-3+5}[/tex]
[tex]= \frac{5}{2}[/tex]
Thus the above answer is right.

Determine if the graph shows two quantities that vary directly. If possible, determine the constant of proportionality using the formula K = y/x
Answer:
Option C is correct option.
Step-by-step explanation:
We need to find k constant of proportionality
In the graph below let us take the values of x and y
x=150 , y=50
x=300, y=100
x=450, y=150
Now finding k using the formula: [tex]k=\frac{y}{x}[/tex]
Putting values of x and y to find k
For x=150 , y=50 k = 50/150, k =1/3
For x=300, y=100 , k=100/300 , k=1/3
For x=450, y=150, k= 150/450 , k=1/3
Since for values of x and y, k = 1/3 is constant so, the graph shows two quantities that vary directly.
So, Option C is correct option.
A watermelon seed is 0.4cm long. How far would a line of 126 stretch?
Answer:
0.504m
Step-by-step explanation:
First, we would multiply 0.4cm by 126 watermelon seeds to find the length of the line in cm.
0.4*126
= 50.4cm
Therefore, the line of watermelon seeds stretches 50.4cm.
Now, because the question wants us to type the answer in meters, we must convert 50.4cm into meters. We do this by dividing 50.4 by 100 since 100cm makes up 1 meter.
50.4/100
= 0.504m
Therefore, the line of watermelon seeds stretches 0.504m.
