There Is Given The Numbers Equals To 8 And DC Equals To 3.2 And BE Quals To 9 And Find BC

Answers

Answer 1

Given:

Consider [tex]AB\parallel DE[/tex] in triangle ABC and [tex]AD=8,DC=3.2,BE=9[/tex].

To find:

The length of BC.

Solution:

Basic proportionality theorem (BPT): If a line intersect the two sides of triangle and parallel to the third side, then that line intersects the other two sides proportionally.

Using Basic proportionality theorem, we get

[tex]\dfrac{AD}{DC}=\dfrac{BE}{EC}[/tex]

[tex]\dfrac{8}{3.2}=\dfrac{9}{EC}[/tex]

On cross multiplication, we get

[tex]8\times EC=9\times 3.2[/tex]

[tex]EC=\dfrac{28.8}{8}[/tex]

[tex]EC=3.6[/tex]

Now,

[tex]BC=BE+EC[/tex]

[tex]BC=9+3.6[/tex]

[tex]BC=12.6[/tex]

Therefore, the length of side BC is 12.6 units.

What is the approximate area?

Answers

Answer:

71.77cm

Step-by-step explanation:

Answer:

71.76 cm^2

Step-by-step explanation:

The composite figure is made up of a rectangle with a missing half circle and a triangle.

area = area of rectangle + area of triangle - area of half circle

For the circle, radius = r = diameter/2 = 7 cm/2 = 3.5 cm.

area = LW + bh/2 - (pi)r^2/2

area = 10 cm * 7 cm + 7 cm * 6 cm/2 + (3.14)(3.5 cm)^2/2

area = 70 cm^2 + 21 cm^2 - 19.24 cm^2

area = 71.77 cm^2

Isabella invested $1300 in an account that pays 4.5% compounded annually. Assuming no deposits or withdrawals are made , find how much money Isabella would have in the account 14 years after her initial investment . Round to the nearest tenth.

Answers

Answer:

$2,407.5

Step-by-step explanation:

To solve this question, we will use the formula for calculating the amount formula as shown;

A =P(1+r)^n

Given that;

P = #$1300

r = 4.5% = 0.045

t = 14years

Substitute

A = 1300(1+0.045)^14

A = 1300(1.045)^14

A = 1300(1.8519)

A = 2,407.5

Hence Isabella would have $2,407.5 in her account after 14years

If a house is built on sand is sinking at a rate of two inches per day which is the change in the height above ground of the house after 11 days

Answers

Answer:

Height of the house will reduce by 22 feet after 11 days.

Step-by-step explanation:

A house is sinking at the rate of 2 inches per day.

That means rate of sinking of the house is 2 inches in a day.

Therefore, house will sink or change in height of the house in 11 days

= Rate o change in height × Number of days

= 2 × 11

= 22 feet

Height of the house will reduce by 22 feet after 11 days.

Is there a linear relationship between the radius and the volume of these cylinders? Explain how you know.

Answers

Answer:

The relationship between r and V is not linear.

Step-by-step explanation:

The volume increases exponentially as r increases linearly.

Volume of a cylinder is directly proportional to the square of its radius, we can say that there is a linear relationship between the radius and the volume of a cylinder.

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Volume of a cylinder is V = πr²h,

where r is the radius

h is the height of the cylinder.

If we keep the height of the cylinder constant and vary the radius, we can see that the volume of the cylinder increases as the radius increases.

In fact, we can express this relationship as a linear equation in the form of y = mx + b,

where y is the volume, x is the radius, m is the slope, and b is the y-intercept.

By rearranging the volume formula, we get V = πr²h, which can be written as y = mx + b, where m = πh and b = 0.

Therefore, since the volume of a cylinder is directly proportional to the square of its radius, we can say that there is a linear relationship between the radius and the volume of a cylinder.
