The side of the edge of the cube is 9. 9cm

<h3>How to determine the length</h3>

Given that the diagonal of a cube measures the square root of 294cm and the diagonal of a face measures 14cm

To find the edge of the face, we know that the face of the cube is a square

Formula for diagonal of a square = \sqrt{2a}

Where is the side of the square

We then have,

\sqrt{2a}  = 14

Make 'a' the subject

a = \frac{14}{\sqrt{2} }

Simplify the surd

a = \frac{14}{\sqrt{2} } × \frac{14}{\sqrt{2} }

a = \frac{14\sqrt{2} }{2}

a = 7\sqrt{2}

a = 9. 9cm

Therefore, the side of the edge of the cube is 9. 9cm

Quadrilateral JKLM is a rhombus. The diagonals intersect at N. If angle JNK equals 5x - 15, find the value of x.
VLD [36.1K]
One property of a rhombus is that the diagonals are perpendicular. This means that the diagonals intersect at 90 degree angles (right angles).

So we know that angle JNK is 90 degrees

angle JNK = 90 degrees
5x - 15 = 90
5x - 15 + 15 = 90+15
5x = 105
5x/5 = 105/5
x = 21

Answer: x = 21

A simple impact crater on the moon has a diameter of 15 kilometers. a complex impact crater has a radius of 30 kilometers. how m
timurjin [86]
The general equation for computing the circumference of a circle is C=\pi d, where C is the circumference, and d is the diameter. (You might also see the equation as C=2 \pi r where r is the radius, because d=2r)

Computing the circumferences of the two circles, we get:
C_{d=15}=\pi (15)=15\pi
C_{d=30}=\pi (30)=30\pi.

To calculate the ratio of two numbers, we can divide one by the other. You can look at this as "How many times does the denominator fit in the numerator?"
\frac{C_{d=30}}{C_{d=15}}=\frac{30\pi}{15\pi}=2
So the circumference of the complex impact crater is 2 times greater than the circumference of the simple impact crater.

The market sells 1 dozen bagels
PIT_PIT [208]

Answer:

market

Step-by-step explanation:

<u>Market</u>

1 dozen bagels = 12 bagels

⇒ Cost per bagel = $7.00 ÷ 12 = $0.58 (nearest cent)

<u>Bagel shop</u>

Cost per bagel = $0.60

As  $0.58 < $0.60 the market is a better buy
