Step-by-step explanation:

Two given triangles have two pairs of congruent sides: one pair of length 7 units and second pair of length 8 units. The third side is common, i.e the lengths of third sides are equal too.

Use SSS theorem that states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.

Which number between 20 and 28 are prime

All the other numbers in between can be divided by something and not become a decimal. Other than 23, it can be divided by anything without becoming a decimal.

Mnenie [13.5K]

Answer:

1920 in³

Step-by-step explanation:

The volume of the water can be gotten by calculation the volume of the aquarium it fills/occupies.

Since the water fills to exactly three inches below the top of the  aquarium, hence the height of the water in the aquarium is given as:

height of water = 13 in - 3 in = 10 in

Therefore the volume of the water in the tank is given by the formula:

Volume of water = height of water * breadth of tank * length of tank

Volume of water = 10 in * 8 in * 24 in = 1920 in³

Naily [24]
$370.00 - $40.00 = $330.00

Rectangle GHIJ is dilated to be a smaller shape. What is the name of the image after the dilation?
prisoha [69]
To know whether the shape is the pre-image or the resulting shape, we need to look at its name.

In this instance, the name of the pre-image is GHIJ.

The resulting name of the shape would be G'H'I'J'.

An apostrophe is placed after every letter to signify that it is the resulting coordinate of the original.
