The required Length is 10cm.

What is length?

220 / 14 gives us 15.

You have to understand that this means 15 whole 14 cm pieces and a Length of 1 piece.

thus 14 * 15 = 210

So 220- 210 = 10

where you know 220- 210 is< 15

Hence, The correct Length is 10cm.

a) The length of the side AB is approximately 11.276 meters.

b) The area of the base of the pyramid is approximately equal to 6.161 square meters.

c) The volume of the pyramid is equal to 16.429 cubic meters.

a) The picture shows a pyramid with a triangular base, the triangle has one obtuse angle and the length of the side AB can be found by the law of the sine:

6 / sin 110° = AB / sin 30°

AB = 6 × (sin 30° / sin 110°)

AB ≈ 3.193 meters

The length of the side AB is approximately 11.276 meters.

b) First, find the length of the side AC:

6 / sin 110° = AC / sin 40°

AC = 6 × sin 40° / sin 110°

AC ≈ 4.104 meters

Second, determine the area of the triangular base by Heron's formula:

s = 0.5 · (AC + BC + AB)

s = 0.5 · (4.104 m + 6 m + 3.193 m)

s = 6.649 m

A = √[s · (s - AC) · (s - BC) · (s - AB)]

A = √[6.649 · (6.649 - 4.104) · (6.649 - 6) · (6.649 - 3.193)]

A ≈ 6.161 square meters

The area of the base of the pyramid is approximately equal to 6.161 square meters.

c) The volume of the pyramid can be found by using the following expression:

V = (1 / 3) · A · h

Where:

If we know that A ≈ 6.161 square meters and h = 8 meters, then the volume of the pyramid is:

V = (1 / 3) · (6.161 m²) · (8 m)

V = 16.429 m³

The volume of the pyramid is equal to 16.429 cubic meters.

No, 12 17 and 14 19 determined ratio are not proportional.

If two ratios depict the same connection, they are said to be proportionate. By writing two ratios as fractions and then reducing them, one may determine if they are proportionate. Your ratios are proportional if the reduced fractions are equal.

We can observe that 17 and 19 are prime numbers,

So, 12 : 17 cannot be simplified further,

Neither 14 : 19 can be simplified.

⇒ 12 : 17 ≠ 14 : 19

∴ We can say that 12 17 and 14 19 determined ratio are not proportional.

Answer:

38.13 m²

Step-by-step explanation:

area of triangle = 1/2 base × height

                          = 1/2 × 4 × 3

                          = 6 m²

Area of rectangle = length ×  width

                             = 6 × 3

                             = 18m²

Area of semi circle = 180/360 × π × radius²

                               = 180/360 × 3.14 × 3²

                               = 14.13 m²

Add all the areas together

6 + 18 + 14.13 = 38.13

f(8) = -208

Step-by-step explanation:

Apply 8 into the equation

f(8) = -3(8)² - 2(8)

      = -192 - 16

      = -208

8 will be your x value since it's implied within the question itself.

Answer:

-208

Step-by-step explanation:

Given function:

[tex]\text{f}(x)=-3x^2-2x[/tex]

To find f(8), substitute x = 8 into the function:

[tex]\begin{aligned}\text{f}(x) & =-3x^2-2x\\\implies \text{f}(8) & =-3(8)^2-2(8)\\& =-3(64)-2(8)\\& =-192-16\\& = -208\end{aligned}[/tex]

Therefore, f(8) = -208.

Step-by-step explanation:

As we know that the value of Complementary angle is always 90°

9x° + 6° + 3x° = 90°

The scale copy of a shape is the resulting shape when the original shape is dilated. Possible scaled rectangles of rectangle A are 12cm by 8cm and 48cm by 32cm .

It is required to find the measurements that could be the dimensions of rectangle B.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

Given :

Length=6 cm

width=4cm

According to given question we have,

Divide the length and the width of the rectangle we get=

k=Length/width

k=6/4

k=1.5

This means that a scaled copy of rectangle A must have a value of 1.5

when the dimensions are divided.

Possible rectangles are:

A. 12cm by 8cm

Divide the length and the width of the rectangle we get,

k=12/8

k=1.5

B. 48cm by 32cm

Divide the length and the width of the rectangle we get,

k=48/32

k=1.5

Therefore, the scale copy of a shape is the resulting shape when the original shape is dilated. Possible scaled rectangles of rectangle A are 12cm by 8cm and 48cm by 32cm .

Parallel lines are lines that never intersect. For this problem, lines l and k are parallel, that is, they are the horizontal lines.

When two parallel lines are crossed by a transversal, the alternate interior angles are between the two parallel lines, one in each side.

Since 1 and 2 are alternate interior angles, Mitch created diagram C.

750ml= 25 fluid oz each glass is 5oz

5/25=5oz

Explanation:

A = last year's value = 290,700

B = this year's value = 312,000

C = change in values

C = B - A

C = 312,000 - 290,700 = 21,300

The positive result shows the increase of 21,300 more motorcycles made this year, compared to last year. A negative C value would represent a percent decrease.

Divide this change over the original.

C/A = (21,300)/(290,700) = 0.07327141382869

which is approximate. Let's say we rounded to four decimal places to get 0.0733 which then converts to the percentage 7.33%

If a region’s average movie theater ticket price in 2007 was $6.51. For 2017, it was estimated to be $8.57, the percent of increase in average movie theater ticket price is 16%

A region's average movie ticket price in 2007 was $6. 51

A region's average movie ticket price in 2017 was $8. 57

we need to use the present value of an annuity formula:

the formula used to determine the present value factor of an annuity is:

present value annuity factor = [1 - 1/(1 + i)ⁿ ] / i

we must divide this into 2 parts:

the first part will deal with the $19,00 monthly payment

the second part deals with the $38,000 monthly payment

i = 9.75% / 12 = 0.8125%

n (first part) = 36

n (second part) = 24

the PV annuity factor for first part = [1 - 1/(1 + 0.8125%)³⁶ ] / 0.8125% = 31.1043

the PV annuity factor for second part = [1 - 1/(1 + 0.8125%)²⁴ ] / 0.8125% = 21.7251

loan = ($219,00 x 31.1043) + ($38,00 x 21.7251)//(1 + 0.8125%)³⁶ = $59092.17 + $82555.38 = $141647.55
