Answer:

C and D are rhombuses

Step-by-step explanation:

C is a rhombus because the shape is a parallelogram with all equal sides. And if the sides are all equal in a parallelogram then it is a rhombus.

D is also a rhombus because the shape is a square with equal sides and with right angles. Furthermore, a square is always a rhombus because of the sides and the right angle.

So the final answer is C and D.

Hope it helped!

Answer:

The length of river frontage for each lot are 96.55 ft. 98.85 ft, 101.15 ft and 103.45 ft.

Step-by-step explanation:

See the attached diagram.

The river frontage of 400 ft will be divided into 84 : 86 : 88 : 90 for each lot as AP, BQ, CR, DS and ET all are parallel.

Therefore, PQ : QR : RS : ST = 84 : 86 : 88 : 90 = 42 : 43 : 44 : 45

Let, PQ = 42x, QR = 43x, RS = 44x and ST = 45x

So, (42x + 43x + 44x + 45x) = 400

⇒ 175x = 400

⇒ x = 2.2988.

So, PQ = 42x = 96.55 ft.

QR = 43x = 98.85 ft.

RS = 44x = 101.15 ft and  

ST = 45x = 103.45 ft

Simplify the following expression 5-⁵/2 x 5⁹/2
yarga [219]

Given:

Consider the given expression is

5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}

To find:

The simplified form of the given expression.

Solution:

We have,

5^{-\frac{5}{2}}\times 5^{\frac{9}{2}}

Using properties of exponents, we get

=5^{-\frac{5}{2}+\frac{9}{2}}           [\because a^ma^n=a^{m+n}]

=5^{\frac{-5+9}{2}}

=5^{\frac{4}{2}}

=5^{2}

=25

Therefore, the simplified form of given expression is 25.

Solve for x round to the newest 10th i’d necessary
docker41 [41]

Answer:

x = 43.7°

Step-by-step explanation:

Reference angle (θ) = x°

Opposite side length = 43

Adjacent side length = 45

Apply the trigonometric function, TOA, which is:

Tan θ = Opp/Adj

Substitute

Tan(x) = \frac{43}{45}

x = Tan^{-1}(\frac{43}{45})

x = 43.7° (nearesth tenth)
