How would you shade a model to show ten thousandths?

1 answer:

3 0

Theres not really a way to show that on here unless i draw you a picture...you must know that 10 thousandths is equal to 1 hundredth. if you draw a 100 by 100 centimeter square on graph paper it will consist of a thousand squares since 100 x 100 is 1000, and if you colored in 10 of those squares, it would be 10 thousandths

Given:

It is recommended that adults consume at least 1,000 mg of calcium every day.

$25x+200y\geq 1000$

Step-by-step explanation:

Let, x be the quantity of milk in ounces and y be the quantity of cheddar cheese in ounces.

A person meets the recommendation, if

$25x+200y\geq 1000$

For option A,

Substitute x=50 and y=2 in the given inequality.

$25(50)+200(2)\geq 1000$

$1250+400\geq 1000$

$1650\geq 1000$

This statement is true. So, option A is correct.

Similarly,

For option B,

Substitute x=0 and y=4.5 in the given inequality.

$25(0)+200(4.5)\geq 1000$

$900\geq 1000$

This statement is false. So, option B is incorrect.

For option C,

Substitute x=10 and y=3 in the given inequality.

$25(10)+200(3)\geq 1000$

$850\geq 1000$

This statement is false. So, option C is incorrect.

For option D,

Substitute x=39 and y=0 in the given inequality.

$25(39)+200(0)\geq 1000$

$975\geq 1000$

This statement is false. So, option D is incorrect.

Therefore, the correct option is only A.

Which equation represents the line that passes through (–6, 7) and (–3, 6)? y = –y equals negative StartFraction one-third EndFr

Answer:

$y=-\frac{1}{3} x+5$

Step-by-step explanation:

Notice that the answers they give you to choose from are all lines in slope y-intercept form, it would be very simple to just find the answer finding yourself the slope and y-intercept of the line in question.

Since they give you two points $(x_1,y_1)$ and $(x_2,y_2)$ for the line, use them to find the slope of the line that goes through them, with the formula: $slope=\frac{y_2-y_1}{x_2-x_1} =\frac{7-6}{-6-(-3)} =\frac{1}{-3} =-\frac{1}{3}$
