A trapezoid is isosceles if and only if

(1) The base angles are congruent

(2) The diagonals are congruent

(3) The opposite angles are supplementary

So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".

what is the volume of the hamsta snack box with a width of 1 1/2 inches, a length of2 1/2 inches, and a height of 4 inches

jenyasd209 [6]

Given:

The width of the snack box is $1 \frac{1}{2} \ inches=\frac{3}{2} \ inches$

The length of the snack box is $2 \frac{1}{2} \ inches=\frac{5}{2} \ inches$

The height of the snack box is 4 inches.

We need to determine the volume of the hamsta snack box.

Volume of the box:

The volume of the box can be determined using the formula,

$V=L \times W \times H$

where L is the length, W is the width and H is the height of the box.

Substituting the values, we get;

$V=4 \times \frac{3}{2} \times \frac{5}{2}$

Simplifying, we get,

$V=\frac{60}{4}$

$V=15 \ in^3$

Thus, the volume of the Hamsta snack box is 15 cubic inches.

Cherries cost 4.35 and onions cust 0.98 per pound .lacey has 21.45 to spend .how many pounds of cherries can Lacey afford if she

sweet [91]

Answer:

$\large \boxed{\text{4.25 lb}}$

Step-by-step explanation:

$\text{Cost of onions} = \text{3 lb} \times \dfrac{\text{0.98 }}{\text{1 lb}} = \text{2.94}$

Remaining money = Money available - Cost of onions = 21.45 - 2.94 = 18.48

I lb of cherries costs 4.35 , so

$\text{Pounds of cherries } = 18.48 \times \dfrac{\text{1 lb cherries}}{\text{4.35}} = \text{4.25 lb of cherries}\\\\\text{Lacey can afford to buy $\large \boxed{\textbf{4.25 lb}}$ of cherries.}$
