SURFACE AREA!!! PLEASE HELP

Each piece of ribbon that had been cut has a length of approximately 3.7 m.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The total length of ribbon to tie 12 gifts is calculated as,

⇒ 12 gifts × 1.85 m/gift = 22.2 m

The length of the ribbon remaining is calculated as,

Total length = [22.2 / (1/3)] x 2/3

Total length = 66.6 x 2/3

Total length = 44.4

The length of each piece of ribbon that had been cut is calculated as,

Length of each piece = 44.4 m ÷ 12 = 3.7 m

Answer:

The product of its roots is 6.

Step-by-step explanation:

Let [tex]m\cdot x^{2}-(6\cdot m +1)\cdot x+(m^{3}+m^{2}+4) = 0[/tex], all roots are calculated by Quadratic Formula:

[tex]r_{1} = \frac{6\cdot m +1 + \sqrt{(6\cdot m + 1)^{2}-4\cdot m\cdot (m^{3}+m^{2}+4)}}{2\cdot m}[/tex] (1)

[tex]r_{2} = \frac{6\cdot m +1 - \sqrt{(6\cdot m + 1)^{2}-4\cdot m\cdot (m^{3}+m^{2}+4)}}{2\cdot m}[/tex] (2)

According to statement, we know that:

[tex]r_{1}+r_{2} = 7[/tex] (3)

By applying (1) and (2) in (3), we have the following expression:

[tex]\frac{6\cdot m +1}{m} = 7[/tex]

[tex]6\cdot m + 1 = 7\cdot m[/tex]

[tex]m = 1[/tex]

If we know that [tex]m = 1[/tex], then the roots of the polynomial are, respectively:

[tex]x^{2}-7\cdot x +6 = 0[/tex]

[tex]r_{1} = 6[/tex]

[tex]r_{2} = 1[/tex]

And the product of the roots is:

[tex]r_{1}\cdot r_{2} = 6[/tex]

The product of its roots is 6.

Answer:

C

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 14 and h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 14 × 8 = 7 × 8 = 56 in² → C

Step-by-step explanation:

Simplify the equation to find the value of a.

Subtract 4a from both sides:

[tex] - 3a - 15 = - 3[/tex]

Add 15 to both sides:

[tex] - 3a = 12[/tex]

Divide each side by -3:

[tex]a = - 4[/tex]

Using proportions, it is found that the APR was of 6.3%.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, 4.7% was paid in interest in 9 months. The APR is the amount that would be paid in a year, that is, 12 months.

Hence, the rule of three is:

9 months - 4.7%

12 months - x%

Applying cross multiplication:

[tex]9x = 12(4.7)[/tex]

[tex]x = \frac{12 \times 4.7}{9}[/tex]

[tex]x = 6.3[/tex]

The APR was of 6.3%.

Step-by-step explanation:

Here is the complete question

A tree is standing behind a building. 2/5th of the height of the tree can be seen and the rest is hidden by the building. The building is 12 metres high. What is the height of the tree?

If 2/5 of the tree can be seen the tree covers ( 1 - 2/5) 3/5 of the tree. If the  building is 12 metres high, it means that 2/5 of the building is 12m high

the height of the tree = 12 x (5/2) = 30m

Step-by-step explanation:

Answer:

AB = 74°

Step-by-step explanation:

Minor arc AB is equal to the measure of the central angle APB , then

∠ APB = 360° - 286° = 74° , thus

minor arc AB = 74°

Arc measure of minor arc AB on circle P =  74 degrees

In the given circle,

Arc measure of major arc = 286 degree

Since we know that,

Measure of complete circle = 360 degree

Therefore,

Angle of minor sector = 360 - 286

                                     = 74 degree

We also know that,

A circle sector is a segment or component of a circle made up of an arc and its two radii. A circle's sector can be compared to the form of a pizza slice. A sector is generated when two circle radii meet at both ends of an arc. An arc is merely a part of the circle's circumference.

Since,

Angle of sector = measure of arc

Hence,

Measure of minor arc = 74 degree.

Given two intersecting chords

Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

2x × 12 = 15(x + 3) , that is

24x = 15x + 45 ( subtract 15x from both sides )

9x = 45 ( divide both sides by 9 )

x = 5
