First you are using the pothagorean theorem which is a^2+b^2=c^2. You have a and b, so you should plug them in to get 4^2+4^2=c^2. Then simplify it some more to 16+16=c^2. Now finish simplifying to c^2=32. Now take the square root of each side and you have your answer. So your answer will be c=√32 or c is about 5.66.

hodyreva [135]

Answer: This kind of advertising is accurate.

Step-by-step explanation:

Since we have given that

Cost of their most popular meals are as follows:

$\$7,\$8,\$8,\$12,\$13,\$15,\$17,\$18,\ and\ \$20$

As we have given that the mode cost of their most popular meals is $8.

As we know that "Mode" refers to the most occurring number that we can found in the data.

Here, we can see that $8 occurs 2 times , which is the most occurring cost among them.

Hence, Mode = $8.

So, This kind of advertising is accurate.

Answer:

$x \geq 15$

Step-by-step explanation:

Solving an inequality is very similar to solving an equation, one uses inverse operations. The only major difference between the two is that when one multiplies or divides an inequality by a negative number, one must remember to flip the inequality sign to ensure that the inequality remains true. In this situation, such a rule does not come into play.

$\frac{x}{5} - 8 \geq -5$

Inverse operations,

$\frac{x}{5}-8 \geq -5\\ +8\\\\\frac{x}{5} \geq 3\\*5\\\\x \geq 15$
