Answer:

=193.2 cm

Step-by-step explanation:

Figure out the triangles first
Area= Base times Height divided by 2
first figure out one triangle A= (6)(5.2)/2 = 15.6 (brackets means times and the slash means divide
times it by 2 so you get the area of both triangles (15.6)(2)= 31.2
Now figure out the rectangles
Area= Base times Height
A=(6)(9) = 54
Then times it by 3 to get the area of all three triangles
(54)(3)= 162
Now add 162 and 31.2 and you get 193.2 cm

A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glide

NISA [10]

Answer:

20.2 miles

Step-by-step explanation:

This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:

$/hyp/^{2}$ = $/adj1/^{2}$ + $/adj2/^{2}$

$/24/^{2}$ = $/x/^{2}$ + $/13/^{2}$

576 = $x^{2}$ + 169

$x^{2}$ = 576 - 169

= 407

x = $\sqrt{407}$

= 20.1742

x = 20.2 miles

The glider has to fly 20.2 miles to return to the airport.

Evaluate the following expression. 3^-2

Crazy boy [7]

Answer: The simplified form is $\frac{1}{9}$

Step-by-step explanation:

Since we have given that

$3^{-2}$

As we know the "Exponential law":

$a^{-1}=\frac{1}{a^m}$

So, it becomes

$3^{-2}=\frac{1}{3^2}$

Now, at last it becomes,

$3^{-2}=\frac{1}{3\times 3}=\frac{1}{9}$

Hence, the simplified form is $\frac{1}{9}$

A triangle has sides with length of 11 feet 12 feet and 13 feet. Is it a right triangle

krek1111 [17]

Answer:

Step-by-step explanation:

It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,

→ 11²+ 12² = 13²

→ 121 + 144 = 169

→ 265 ≠ 169

<h3>Hence the ∆ is not a right angled triangle </h3>

A number cube is tossed 8 times. What is the probability that the cube never lands on 3?.

tino4ka555 [31]

The probability that the cube never lands on 3 is (D) 23.3%.

<h3>What is probability?</h3>

A probability formula can be used to calculate the likelihood of an occurrence by simply dividing the favorable number of possibilities by the entire number of possible outcomes.

To find the probability that the cube never lands on 3:

Given -

Number cube toss = 8

Required

Probability of not landing on 3.

First, we need to get the probability of landing on 3 in a single toss.

For a number cube,

n(3) = 1 and n(total) = 6

So, the probability is P(3) = 1/6

First, we need to get the probability of not landing on 3 in a single toss.

Opposite probability = 1.

So, P(3) = P(3') = 1.

Make P(3') the subject of the formula.

P(3') = 1 - P(3)
P(3') = 1 - 1/6
P(3') = 5/6

In 8 toss, the required probability is (P(3'))⁸

This gives:

P = (5/6)⁸
P = 390625/1679616
P = 0.23256803936

Approximate to 1 decimal place, P = 23.3%.

Therefore, the probability that the cube never lands on 3 is (D) 23.3%.
