$2 \pi r$ is the formula you need do you divide 47.1 by 2 and $\pi$ so its aproximatly 7.5 or 7.496

Answer:

yes , 33^2 + 56^2 = 65^2 and obtuse

Step-by-step explanation:

<h2><u>Question 3</u></h2>

make use of the Pythagoras theorem

which is :

c^2 = a^2 + b^2

where c is the hypotenuse.

now put the values in the equation

65^2 = 56^2 + 33 ^2

the answer is :

<u>yes , 33^2 + 56^2 = 65^2</u>

<u></u>

<h2><u>Question 4</u></h2>

<u />

note if :

c^2 = a^2 + b^2 ----------- right

c^2 < a^2 + b^2------------ acute

c^2 > a^2 + b^2------------- obtuse

hence :

16 + 30 > 38

therefore its : <u>obtuse </u>

Paul's mom sent him to the grocery store with $10 to buy bread and cheese for sandwiches. Paul picked out a loaf of bread that c

lutik1710 [3]

Given:

Total amount = $10

Cost of loaf of bread = $3.25

Cost of cheese = $5.99 per pound

Each slice weights = 0.04 pounds.

To find:

The inequality for the number of slices that Paul can afford to buy.

Solution:

Let x be the number of slices that Paul can afford to buy.

Weight of on slice is 0.04 pounds. So, weight of x slices is 0.04x pound.

Cost of cheese = $5.99 per pound

So, total cost of cheese for x slices = $5.99 × 0.04x

Now, Paul has $10 to buy bread and cheese for sandwiches. Cost of loaf of bread is $3.25.

$3.25+(5.99\times 0.04x)\leq 10$

$0.2396x\leq 10-3.25$

$0.2396x\leq 6.75$

Divide both sides by 0.2396.

$x\leq \dfrac{6.75}{0.2396}$

$x\leq 28.172$

The maximum integer value of x is 28.

Therefore, the required inequity is $3.25+(5.99\times 0.04x)\leq 10$ and 28 number of slices Paul can afford to buy.
