Answer:

Lin has 11 acorns ⇒ answer D

He subtract 4 from 7 instead of add 4 to 7

Step-by-step explanation:

- Lin has 4 pinecones and some acorns

- She has 7 fewer pinecones than acorns

- The meaning of 7 fewer pinecones than acorns is the number of the

pinecones is less than the number of acorns by 7

∵ She has 4 pinecones

∵ She has 7 fewer pinecones than acorns

- The number of pine cones is less than the number of acorns by 7

∴ 4 = number of acorns - 7

- Add 7 to both sides

∴ 11 = number of acorns

* Lin has 11 acorns

- Tom choose answer A which is 3

- He made a mistake in the equation

- He put ⇒ number of the acorns = 7 - 4 not 7 + 4

∴ number of acorns = 3

* He subtract 4 from 7 instead of add 4 to 7

Find Arc measure of ABC

Softa [21]

Answer:

268°

Step-by-step explanation:

$In\: \odot O,$ AB is diameter.

So, $\widehat{AB} \:\&\: \widehat {BA}$ are semicircular arcs.

$\therefore m\widehat {AB} =m\widehat {BA} = 180\degree$

$\because \: m\widehat {BC} = m\widehat {BA} - m\widehat {CA}$

$\therefore \: m\widehat {BC} = (180-92)\degree$

$\therefore \: m\widehat {BC} =88\degree$

$\because m\widehat {ABC} = m\widehat {AB}+m\widehat {BC}$

$\therefore m\widehat {ABC} = 180\degree+88\degree$

$\therefore m\widehat {ABC} = 268\degree$

Prove:

Levart [38]

Given the statement, "If $n^2$ is odd, then $n$ is odd," its contrapositive claims that, "If $n$ is not odd, then $n^2$ is not odd."

So assume $n$ is not odd, i.e. $n$ is even. This means there is an integer $k$ for which $n=2k$ . Squaring this gives $n^2=(2k)^2=4k^2$ .

Well, we can write $4k^2=2(2k^2)$ , and $2k^2$ is just another integer, which means $4k^2=(2k)^2=n^2$ must be even.

Which expression represents the word phrase 6 decreased by one-third of a number? a. 6+13−x b. 6+13+x c. 13⋅x−6 d. 6−13⋅x

KiRa [710]

The answer is D but it is written
$6 - \frac{1}{3} x$
The word decreased means to subtract but as the expression states 1/3 of a number, 6 is subtracted by 1/3 times whatever number X represents.
