Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Height of trapezoid = 4 ft

Length of longer side=  'a' = 13 ft

Length of shorter side = 'b' = 9 ft

Due to height of 4 meter there will be right angle triangle at the corners.

In right angled triangle:

H^2=B^2+P^2\\\\H^2=4^2+2^2\\\\H^2=16+4\\\\H^2=20\\\\H=\sqrt{20}\\\\H=2\sqrt{5}\ ft

Since it is isosceles trapezoid, then there two non parallel sides should be equal.

So, Perimeter of isosceles trapezoid is given by

13+9+2\sqrt{5}+2\sqrt{5}\\\\=22+4\sqrt{5}\\\\=30.94\ ft

Hence, option 'c' is correct.

Answer:

C

Step-by-step explanation:

The perimeter of a figure is found by adding the sides of all the figures. The figure has sides 13 and 9. Its height is 4 so each of those sides is about 4 feet. So the perimeter is 13+9+4+4 = 30

C is the best solution.

A dial combination lock has dials numbered 0 to 5. The lock is set to an even number. How many different numbers could it be?
Butoxors [25]

The number of combinations will be 6 for even numbers.

<h3>What is the combination?</h3>

The arrangement of the different things or numbers in a number of ways is called the combination.

Given that:-

  • A dial combination lock has dials numbered 0 to 5. The lock is set to an even number. How many different numbers could it be?

The total sample numbers are from 0 to 5 which are 0,1,2,3,4,5.

The even numbers are 0,2,4.

The combinations will be given by:-

C = 3!

C = 3 x 2 x1

C = 6

Therefore the number of combinations will be 6 for even numbers.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at
antiseptic1488 [7]

Answer:

W = 6t + 90

Step-by-step explanation:

Given :

Starting weight = intercept = 90 kg

Weight gained after 8 months = 138 kg

Using the slope intercept relation ;

We can obtain the rate of change, slope ;

y = mt + c

m = slope ; t = time after t months ; c = intercept

y = weight gained after 8 months

138 = 8m + 90

138 - 90 = 8m

48 = 8m

m = 48 / 8

m = 6

Hence, slope intercept equation equals :

W = 6t + 90

I need help with this please asap
Alex

Step-by-step explanation:

We can prove that the triangles are congruent using the SAS method.

It's given that GH and JH are congruent (S)

Angle GHF and Angle IHJ are equal since they are vertically opposite (A)

It's given that FH and HI are congruent (S)

Thus, the triangles are congruent, which implies that the remaining sides are equal.
