What doubles fact can help you solve 6+5=11?

Answers

Answer 1

Answer: The correct answer is this one: "C. 5+5=10 "

From the equation 6 + 5 = 11
We can have the doubles : 5 + 5 + 1 = 11
The doubles plus one are the facts in which one addend is larger than the other by one.

Here are the choices.

A- 8+8=16 B- 7+7=14
C- 5+5=10 D- 4+4=8

-6

Step-by-step explanation:

The given translation is

$T_(-3,-8) (x,y)$

Which means that the original figure will be moved 3 units to the right and 8 units downwards.

Remember, when it comes to translations, when we subtract units to $x$ that means the figure will be moved rightwards. And if we subtract units from $y$ , that means the figure will be moved downwards.

So, the original figure has as vertex B(1,2). If we apply the transformation to its vertical cordinate $y=2$ , we would have

$y'=2-8=-6$

Therefore, the right answer is the third choice -6.

in 2004, 510,000 acres of farmland in region were devoted to growing nuts. by 2011, the number of acres used to grow nuts had increased to 830,000. find the avarage rate of change in the number of acres in a region used to grow nuts from 2004 to 2011

Answers

Consider the (x, y) coordinates to be: (2004, 510000) and (2011, 830000).

Average rate of change is another name for slope, So, use the slope formula: $m = (y2 - y1)/(x2 - x1)$

$m = (830,000 - 510,000)/(2011 - 2004)$

$m = (320,000)/(7)$

Answer: 320,000 acres every 7 years

Answer: 45714 per year.

Step-by-step explanation:

Given : In 2004, 510,000 acres of farmland in region were devoted to growing nuts. by 2011, the number of acres used to grow nuts had increased to 830,000.

Change in acres of farmland from 2004 to 2011 = 830000-510000=320,000

Change in year = 2011-2004=7

The average rate of change is given by :-

$\frac{\text{Change in acres of farmland}}{\text{Change in year}}\n\n=(320000)/(7)=45714.2857143\approx45714 \text{[Rounded to the nearest integer.]}$

Hence, the average rate of change in the number of acres in a region used to grow nuts from 2004 to 2011 is 45714 per year.
