Answer:

x = 5

Step-by-step explanation:

3x + 5 = 2x + 10

subtract 5 from both sides:

3x + 5 - 5 = 2x + 10 - 5

3x = 2x + 5

subtract 2x from both sides:

3x - 2x = 2x + 5 - 2x

x = 5

The distance from the top of the tree to the tip of the shadow is 12.8 ft  

According to the Pythagorean theorem, In a right-angled triangle, the sum of the squares of the side will equal the square of the hypotenuse.
Here hypotenuse is the longest side.

=> Hoptenuse² = side² + side²

Here we have

The length of the tree = 10 feet

Length of shadow = 8 feet

Here we need to find the distance from the top of the tree to the tip of the shadow  

If we join the top of the tree to the tip of the shadow we will observe a right-angled triangle as shown below

From the figure,

AC² = AB² + BC²    [ ∵ ABC is right angle triangle ]

=> AC² = 10² + 8²  

=> AC² = 100 + 64

=> AC² = 164

=> AC = 2√41

=> AC = 12.8 ft

Therefore,

The distance from the top of the tree to the tip of the shadow is 12.8 ft

Answer:

b) 12.8 feet

Step-by-step explanation:

Now we have to,

→ find the required distance.

Forming the equation,

→ x² = 10² + 8²

Then the distance will be,

→ x² = 10² + 8²

→ x² = 100 + 64

→ x² = 164

→ x = √164

→ [ x = 12.8 feet ]

Hence, distance is 12.8 ft.

Answer:

  ∆JGF ≅ ∆GJH by the SAA Postulate

Step-by-step explanation:

Given a figure showing two triangles with a common side, and two marked angles not at either end of that side, you want to know the applicable congruence postulate.

The letters S and A in the congruence postulate references refer to "Side" and "Angle". The sequence of the letters corresponds to the sequence of corresponding parts in the triangles.

In the given figure, two angles in each triangle are marked with a single arc and a double arc. The triangles share a side that has the double-arc angle at one end. Hence, the sequence of corresponding parts can be seen to be (common) Side - (double-arc) Angle - (single-arc) Angle. The SAA congruence postulate applies.

Step-by-step explanation:

∠ ADB and ∠ AOB sum to 180° , that is

56° + ∠ AOB = 180° ( subtract 56° from both sides )

∠ AOB = 124°

An angle on the circle is half the central angle subtended on the same arc , so

∠ BCA = [tex]\frac{1}{2}[/tex] ∠ AOB = [tex]\frac{1}{2}[/tex] × 124° = 62°

The annual dividend for 500 shares was $710.

The annual dividend is a function of the dividend per share and the number of shares held by a stockholder.

Dividends are always declared per share with a stated dollar amount or percentage.

Dividends represent the portion of the profits earned by an entity that it decides to distribute to the shareholders.

Dividends are a kind of financial reward to stockholders for their investment in the entity.

The dividend per share = $1.42

Market price per share = $96

The number of shares held = 500

The dividend received for the year = $710 ($1.42 x 500)

Thus, the holder of 500 shares in Walt Disney Co. will get $710 in a year the company declared and paid a $1.42 annual dividend.

As corresponding angles ∠5 and ∠8 are equal. Hence line x is parallel to line z by converse of corresponding angles theorem.

What does converse of corresponding angles theorem states?

If two lines and a transversal form corresponding angles that are congruent, then the lines are parallel.

How can we show two lines are parallel to each other?

We can show lines are parallel by finding a pair of corresponding angles that are congruent.

Proving if two lines are parallel then third line is parallel too.

According to the given data:

       Therefore, ∠5 ≅ ∠7 (i.e. corresponding angles)

       ∠5 = ∠7

       ∠6 ≅ ∠8 (Corresponding angles are equal)

        ∴ Measure of angles is also equal ⇒ ∠6 = ∠8

       ∠5 = ∠8 (transitive property of equality of angles which says if

                               ∠a = ∠b and ∠b = ∠c then ∠a = ∠c)

       ∠5 ≅ ∠8 (If measure of angles is same then they are congruent)

Therefore, line x || line z

The probability of of a random student having blue eyes and dark hair

 is 35% .

let consider the total students in the school be (U) = 100%

out of them ,

students having blue eyes (A) = 60%

students having  dark hair (B) = 55%

students with neither blue eyes nor dark hair (A∪B)' = 20%

let the students with blue eyes and dark hair be (A∩B) = x %

Then according to the set theorem

U = n(A∪B) + n(A∪B)'

U = n(A) + n(B) - n(A∩B) + n(A∪B)'

100 = 60 + 55 - x +20

The required value of a₄ is 10,202 to the given recursive formula.

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The given recursive formula in the question as:

aₙ = (aₙ ₋₁ )² + 1 ....(i)

And, a₁ = 3

Substitute the value of a₁ = 3 in equation (i), and solve for n = 2

a₂ = (a₁)² + 1

a₂ = (3)² + 1

a₂ = 9 + 1 = 10

Substitute the value of a₂ = 10 in equation (i), and solve for n = 3

a₃ = (10)² + 1

a₃ = 100 + 1 = 101

Substitute the value of a₃ = 101 in equation (i), and solve for n = 4

a₄ = (101)² + 1

a₄ = 10,201 + 1

a₄ = 10,202

The total quantity of diesel fuel is 15.75 gallons.

The total quantity of diesel fuel can be calculated by summing up all the values. But, firstly converting quarts and pint into gallons.

1 quart = 0.25 gallon

For first container, 3 quarts = 0.25 × 3

3 quarts = 0.75 gallon

For second container, 2 quarts = 0.25 × 2

2 quarts = 0.5 gallon

For third container, it has 0.25 gallon

1 pint = 0.125 gallon

For first and third container, it has 0.125 gallon

So, amount of diesel fuel in first container = 3 + 0.75 + 0.125

Amount of diesel fuel in first container = 3.875 gallons

Amount of diesel in second container = 5 + 0.5

Amount of diesel in second container = 5.5 gallons

Amount of diesel in third container = 6 + 0.25 + 0.125

Amount of diesel in third container = 6.375 gallons

So, the total quantity of diesel fuel = 3.875 + 5.5 + 6.375

The total quantity of diesel fuel = 15.75 gallons

Hence, the total quantity is 15.75 gallons.
