Answer: Option B

She should use the fact that the

opposite sides of a parallelogram are

congruent and then use the

Pythagorean theorem.

We cannot use the diagonals of square property because this is a rectangle, opposite angles will also not work, and we cannot use the diagonal property because thats what we have to prove.

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.

A metal soup can is 4 in. tall and has a diameter of 6 in.
sukhopar [10]

The amount of metal used to make the can = surface area of cylindrical can, which is: D. 42π in².

<h3>What is the Surface Area of a Cylinder?</h3>

A can is a cylinder.

Surface area of a cylinder = 2πrh + 2πr²

Thus:

Amount of metal used to make the can = surface area of the can

r = 6/2 = 3 in.

h = 4 in.

Therefore:

Surface area = 2×π×3×4 + 2×π×3²

Surface area = 24π + 18π

Surface area = 42π in².
