Answer:

7√2 / 2

Step-by-step explanation:

An isosceles right triangle is also known as a 45-45-90 triangle. For such a triangle, the hypotenuse (long side) is √2 the legs.

s√2 = 7

s = 7/√2

s = 7√2 / 2

You can also show this with Pythagorean theorem.

What is the exact value of the expression the square root of 294. - the square root of 24. + the square root 54.? Simplify if po

dalvyx [7]

My solution to the problem is as follows:

sqrt(294) - sqrt(24) + sqrt(54)
= sqrt(49 * 6) - sqrt(4 * 6) + sqrt(9 * 6)
= sqrt(49)*sqrt(6) - sqrt(4)*sqrt(6) + sqrt(9)*sqrt(6)
= 7*sqrt(6) - 2*sqrt(6) + 3*sqrt(6)
= (7 - 2 + 3)*sqrt(6)
= 8*sqrt(6)
= sqrt(64)*sqrt(6)
<span>= sqrt(384)

= 8*sqrt(6)

Therefore, the answer is letter B, 8 square root of 6
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!

A store has clearance items that have been marked down by 60%. They are having a sale, advertising an additional 15% off clearan

astra-53 [7]

Answer: 34%

Step-by-step explanation:

Given

Price is marked down by 60% with an additional discount of 15% on the marked down price

Suppose x is the original price of the item

After marking down, it is

$\Rightarrow x-x\times 0.6=0.4x$

after additional discount it is

$\Rightarrow 0.4x(1-0.15)=0.4x\times 0.85=0.34x$

Effective discount on the item is

$\Rightarrow \dfrac{x-0.34x}{x}\times 100=66\%$

Thus, a person is paying $100-66=34\%$ of the original price

Which statements are true regarding the area of circles and sectors? Check all that apply.

AveGali [126]

Answer:

The correct options are a,b.

Step-by-step explanation:

The area of sector of a circle equals

Area of a sector = $\theta r^{2}$

where

$\theta$ is the angle subtended at the center by the sector

$r$ is the radius of circle

This indicates that area of the sector depends on:

1) Radius of circle

2) Angle subtended at the center by the sector

3) Area of sector does not depend on pi.

Also if we know the area of the sector only we cannot calculate area of area of whole triangle as we need one more information either angle of the sector and vice versa.
