Answer 1

Answer:

EF² = FA²+ EA²

20² = 12² + FA²

400 -144 = FA²

256 =FA²

16cm = FA

Now in Δ DAG

DG² = AG² + DA²

13² = 12 ²+ DA²

169 -144 = DA²

25 = DA²

5cm = DA

Then that means diagonal DF = DA + FA

= 5 + 16

= 21cm

Answer 2

The value of the other diagonal DF is 21.66 cm.

What is Pythagoras Theorem?

The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to the Pythagorean theorem.

Given:

The top two sides measure 20 cm each and the bottom two sides measure 13 cm each.

EG= 24 cm.

As, Diagonal ED divides the diagonal DF into two equal parts.

Now, Using  Pythagoras theorem in triangle DOG

x²/4 + y² = 13²= 169

and, Using  Pythagoras theorem in triangle EOD

x²/4 + (24 -y)² = 20²= 169

x²/4 + 576  -48y+ 169 - x²/4 = 400

-48y= -345

y= 7.1785

now, y²= 169 - x²/4

51. 6601 = 169 - x²/4

x/2 = 10.83

x = 21.66 cm

Thus, the other diagonal DF is 21.66 cm.

A number cube has 6 different faces, numbered 1 to 6. All faces have an equal probability of being rolled. What is the probability of rolling a 5?


please no links or weird pictures!

Answers

Answer:

its a 1/6 chance

Step-by-step explanation:

each face has a 1/6 chance of being rolled since there are 6 faces

Answer:

Answer:

40.2 % to the nearest tenth.

Step-by-step explanation:

Probability( 6 on one roll = 1/6).

Probability (6 on first roll and NOT 6 on the next 5 rolls) = 1/6 * (5/6)^6

= 3125/46656

= 0.06698

Only 1 six rolled can happen in  6 different ways ( where the 6 is on the second, third roll etc.)

So the required probability is 0.06698 * 6 = 0.40188.

∠A and \angle B∠B are complementary angles. If m\angle A=(6x+22)^{\circ}∠A=(6x+22) ∘ and m\angle B=(7x+16)^{\circ}∠B=(7x+16) ∘ , then find the measure of \angle B∠B.

Answers

Answer: B = 44

Step-by-step explanation:

The measure of ∠B = 44°.

We have two angles ∠A and ∠B which are complementary of each other.

We have to find the measure of ∠B.

What are Complementary angles?

Two angles are said to be complementary if their sum is equal to 90°.

Mathematically -   x + y = 90°

According to the question -

∠A = (6x+22)°

∠B = (7x+16)°

Now, ∠A and ∠B are Complementary angles. Therefore -

∠A + ∠B = 90°

(6x + 22) + (7x + 16) = 90

13x + 38 = 90

13x = 52

x = 4

Therefore -

∠B = 7x + 16 = 7 x 4 + 16 = 44°.

Hence, the measure of ∠B = 44°.

Jarvis a 41-year old male, bought a $115,000, 20yr life insurance policy thru his employer. Jarvis is paid weekly. How much is deducted from each of his paychecks for life insurance?

Answers

Answer: $30.25

Step-by-step explanation:

Amount of insurance policy bought = $115,000

Number of years for the life insurance = 20 years.

From the chart, the Annual premium per $1000 of coverage for 20 years for a male of 40-44 years is $13.68. Therefore, the annual premium will be:

= (115,000 / 1,000) × $13.68

= 115 × $13.68 =

= $1,573.20

Note that 52 weeks make a year. Therefore, the weekly deductions will be:

= $1,573.20 / 52

= $30.25

Therefore, the correct option is D.

Given that;

⇒ y is directly proportional to x³

Hence, We get;

⇒ y = kx³

Here, y  17 at x = 4;
