HELPPPP <br><br>which value is equal to 2✓28-5✓63?<br><br>a-37✓7<br>b-✓7<br>c-11✓7<br>d✓7​
IrinaVladis [17]

Answer:

c

Step-by-step explanation:

if I understand this right, then the expression is

2×sqrt(28) - 5×sqrt(63)

let's look for squared factors in the numbers under the square roots.

28 = 4×7 (4 is a squared number)

63 = 9×7 (9 is a squared number)

so,

2×sqrt(4×7) - 5×sqrt(9×7) =

= 2×2×sqrt(7) - 5×3×sqrt(7) = 4×sqrt(7) - 15×sqrt(7) =

= (4 - 15)×sqrt(7) = -11×sqrt(7)

A spiral staircase turns $270^\circ$ as it rises 10 feet. The radius of the staircase is 3 feet. What is the number of feet in t
Anastaziya [24]

The number of feet in the length of the handrail is 17.3 ft.

The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle

The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft  turned through 270°= (3/4) of a whole revolution

(3/4) (2pi) (3)  =  (9/2)pi ft =   4.5 pi ft

The side of the rectangle will be the rise of the staircase = 10ft

And the diagonal of the rectangle will be the length of the handrail

We can use the Pythagorean Theorem to solve this

Handrail length = √ [ (4.5 pi)^2 + 10^2 ]  ≈  17.3 ft

Pythagorean theorem is the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

Evaluate - 6 – (-6) + 7 + (-4) + (-1).<br><br> What’s the answer please!!
elena55 [62]

Answer:

The answer is 2.

Step-by-step explanation:

Given: - 6 - (-6) + 7 + ( - 4) + ( - 1)

= - 6 + 6 + 7 - 4 - 1

= 6 + 7 - 6 - 4 - 1

= (6 + 7) - (6 + 4 + 1)

= 13 - 11

= 2

Hence, the answer.
