Answer:

Follow the rule of BODMAS (brackets, of, division, multiplication, addition, subtraction)

Ans: 58

Step-by-step explanation:

42 + 4(6 - 2) Process --> 6 - 2 = 4

= 42 + 4 * 4 Process --> 4 * 4 = 16

= 42 + 16 Process --> 42 + 16 = 58

= 58

Hope this helps :)

Factor out it by 2.
2(b² - 13b + 40) = 0
b² - 13b + 40 =0
This equation can be solved using the quadratic formula. If you know what a quadratic formula is, then you can get the two values for b. For instance,
(b - 8)(b - 5) = 0

Separate the two "roots", you will get:
b - 8 = 0
b = 8
and
b - 5 = 0
b = 5

Therefore the two values of b are 8 and 5.

how many cubic yards of concrete will be needed to replace a section of sidewalk 150ft long, 5ft wide and 4 inches thick

zepelin [54]

4 inches = 1/3 foot

So the volume of that section is (150ft x 5ft x 1/3 ft) = 250 cubic feet

The whole trick to this question is knowing
how many cubic feet make 1 cubic yard.

1 yard = 3 ft

(1yd x 1 yd x 1yd) = 1 yd³

(3ft x 3ft x 3ft) = (3 ft)³ = (3)³ x (ft)³ = 27 ft³ <===

For the sidewalk project,

250 ft³ = (250 / 27) = 9.26 yard³ .

I think the way concrete contractors operate, they'll
want you to order and pay for 10 cubic yards.

A right rectangular pyramid is sliced vertically (down) at the red line by a plane not passing through the vertex of the pyramid

crimeas [40]

The cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a rectangle. Hence, 4th option is the right choice.

If the peak of the rectangular pyramid is directly above the center of the base, it creates a perpendicular to the base, indicating the height of the pyramid. This type of rectangular pyramid is known as the right rectangular pyramid.

A rectangle is a quadrilateral, that is a closed figure with 4 line segments, with all four interior angles at 90°.

When we slice a right rectangular pyramid vertically down at the red line by a plane, not passing through the vertex, of the pyramid will be a dilated image of its base.

A dilated image is an enlarged or diminished image of the preimage, similar with all angles.

Thus, the cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a rectangle. Hence, 4th option is the right choice.
