Volume of a pyramid: 1/3(length x width x height)

Since it is a square pyramid, the base is a square, which means that the length and width of the base is 7 cm (the same).

Plug the numbers into the formula.

1/3(7 x 7 x 12) = 196

The volume is 196 cm³.

In the diagram, ABCDE is a regular pentagon.
RSB [31]

The shape ABCDE is a regular pentagon with five sides, such that the five sides are congruent

<h3>Part A: Calculate ∠BAE</h3>

The angle BAE is a vertex angle, and it is calculated using:

BAE = 180 * (n - 2)/n

Where n= 5; i.e. the number of sides.

This gives:

BAE = 180 * (5 - 2)/5

Evaluate

BAE = 108°

Hence, the measure of angle BAE is 108°

<h3>Part B: The name of the quadrilateral ABCD</h3>

When the vertices A and B are joined together, the shape becomes a trapezoid.

Hence, the name of the quadrilateral ABCD is a trapezoid.

<h3>Part C (i) Calculate ∠EDX</h3>

See attachment for the new figure.

From the attached figure, we have:

∠EDX + ∠EDC = 180° ---- the sum of angles on a straight line

Where:

∠EDC = ∠BAE = 108°

So, we have:

∠EDX + 108° = 180°

Subtract 108° from both sides

∠EDX = 72°

Hence, the measure of angle EDX is 72 degrees

<h3>Part C (ii) What type of quadrilateral is BDXE?</h3>

The quadrilateral BDXE is a parallelogram.

This is so because the opposite sides of BDXE are parallel, but not congruent

Morris has 2 3/4 gallons of ice tea. He gives 3/7 of it to her friend. How many gallons of ice tea does Morris have left?
lara31 [8.8K]

Answer:

2 \frac{9}{28} gallons of ice tea is left with Morris

Step-by-step explanation:

Morris has 2 3/4 gallons of ice tea. He gives 3/7 of it to her friend.

Morris has 2 3/4 gallons of ice tea

2\frac{3}{4}= \frac{2*4+3}{4}=\frac{11}{4}

He gives 3/7 of it to her friend.

To find how many gallons of ice tea does Morris have left , we subtract 3/7 from 11/4

\frac{11}{4}- \frac{3}{7}

Make the denominators same

\frac{11*7}{4*7}- \frac{3*4}{7*4}

\frac{77}{28}- \frac{12}{28}

\frac{65}{28}

\frac{65}{28} = 2 \frac{9}{28}

I would like to have some help please! ❤ thank youu I need help on the 2 question that is "write three expressions containing ex
Vesna [10]

Answer:

Below

Step-by-step explanation:

Notice that 81 = 9 * 9

So here is the first expression:

● 9^2

9 is 3^2 so 9^2 is 3^4

That's another expression

● 3^4

81 = 9*9 = 3*3*3*3 = 3^3 *3

That's another expression

● 3*3^3

You can keep manipulating the product and create many expressions like:

● 3^2 * 3^2

● 9 * 3^2
