Find the volume of the Canada post mailbox shown below.

harina [27]

Answer:

1,152,112.5 cm3

Step-by-step explanation:

To find the volume of this mailbox we can separate in two parts:

A rectangular prism, with dimensions 180 cm x 70 cm x 85.5 cm and

A triangular prism, with dimensions 25 cm x 70 cm x 85.5 cm.

Now we need to find the volume of both parts:

V_rectangular = 180 * 70 * 85.5 = 1,077,300 cm3

V_triangular = (1/2) * 25 * 70 * 85.5 = 74,812.5 cm3

Finally, we just need to sum the volumes of the parts:

V_mailbox = V_rectangular + V_triangular = 1077300 + 74812.5 = 1,152,112.5 cm3

Find the factors of f(x) given that x = 5 is a zero.

77julia77 [94]

If x = 5 is a zero of the given polynomial, then,
(x - 5) is a factor of the polynomial. [Since, x = 5 or, x - 5 = 0]
Now, divide the polynomial with (x - 5) using long division method. (See the picture)
We get (x^2 - x - 6) as the quotient.
Now, factorise the above polynomial:
(x^2 - x - 6)
= (x^2 - 3x + 2x - 6)
= x(x - 3) + 2(x - 3)
= (x - 3)(x + 2)
Therefore, x^3 − 6x^2 − x + 30 = (x − 5)(x − 3)(x + 2)

Answer:

B.(x − 5)(x − 3)(x + 2)

Hope you could get an idea from here.

Who can help me ! .... thanks

Tasya [4]

Given that there is no any option to choose I am going to help you according to the concepts of Congruent Triangles. Two triangles are congruent if and only if:

1. They have:exactly the same three sides
2. exactly the same three angles.

There are five ways to find if two triangles are congruent but in this problem we will use only two.

First Answer:

ASA criterion: Angle, side, angle. This means that we have two triangles where we know two angles and the included side are equal.

So:

If ∠BAC = ∠DEF and $\overline{AC}=\overline{DE}$

Then ΔABC and ΔEFD are congruent by ASA criterion.

Second answer:

SAS criterion: Side, angle, side. This means that we have two triangles where we know two sides and the included angle are equal.

$If \ \overline{AC}=\overline{DE} \ and \ \overline{BC}=\overline{DF}$

Then ΔABC and ΔEFD are congruent by SAS criterion.

Find the area for the given shape below

Ket [755]

To find the area of a triangle given its base and its height, use the formula A = bh/2.

The base of the triangle is 14m.
The height of the triangle is 10m.

Plug these values into the formula and solve.

A = bh/2
A = 14(10)/2
A = 140/2
A = 70

Answer:
The area of the triangle is 70 m².
