15. In The Drawing, Find The Perimeter Of Triangle BIS.

Answers

Answer 1

Answer:

29.86 units

Step-by-step explanation:

In the triangle BIS, IT is the bisector of angle BIS,

[tex] BI \cong ST.... (given) \\[/tex]

Let BI = ST = x... (1)

By angle bisector property of a triangle, we have:

[tex] \frac{BI}{IS} = \frac{BT}{ST}.... (2)\\\\

\frac{x}{12} = \frac{4}{x}\\\\

x\times x = 12\times 4\\\\

x^2 = 48\\\\

x=\sqrt{48}\\\\

x = 6.92820323\\\\

x = 6.93\\[/tex]

Therefore,

BI = ST =6.93

Perimeter of triangle BIS

= BI + IS + ST + BT

= 6.93 + 12 + 6.93 + 4

= 29.86 units

Answers

Answer:

4 ft per second

Step-by-step explanation:

We are given that it takes 50 seconds to go 200 feet

in order to find the ft/second, we divide by 50

50/50=1

200/50=4

so 4 ft/ 1 second

9. Matt bought a new crate for his dog. The old crate was 8 square feet, and the new crate was 12 square feet. What is the percent increase in the space?

Answers

Solution:

It is given that :

Area of old crate = 8 square feet

Area of the new crate = 12 square feet

Therefore difference in the area = 12 - 8

                                                     = 4 square feet

Now the percentage increase in the area of the crate is given by :

[tex]$=\frac{\text{difference in the area of crate}}{\text{original area of crate}} \times 100$[/tex]

[tex]$=\frac{4}{8} \times 100$[/tex]

= 50%

So the percentage increase in space is 50%

Conditional Statement: If two lines are parallel, then they do not intersect. Converse: If two lines do not intersect, then they are parallel. Inverse: If two lines are not parallel, then they intersect. Contrapositive: If two lines intersect, then they are not parallel. Which statements are true? A) Converse and Inverse B) Inverse and Contrapositive C) Conditional Statement and Converse D) Conditional Statement and Contrapositive

Answers

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

Two or more lines which have no intersections but are not parallel, known as skew lines.

Option D is correct.

Conditional Statement: If two lines are parallel, then they do not intersect.

Converse: If two lines do not intersect, then they are parallel.

Inverse: If two lines are not parallel, then they intersect

Contrapositive: If two lines intersect, then they are not parallel.

Thus,  option (D) Conditional Statement and Contrapositive , is correct.

Converse and Inverse are false because skew lines are a type of lines which are neither parallel nor intersecting in 3D

Step-by-step explanation:

Step 1:  Cross-Multiply

What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides.  So you take the top of the left fraction and multiply it by the bottom of the right fraction.  You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.

[tex]\frac{2}{7}=\frac{6x}{4x+17}[/tex]

[tex](2*4x)+(2*17)=(7*6x)[/tex]

Step 3:  Subtract 8x from both sides

Liza’s age is two more than thrice the age of her younger sister.if her sister is 5 years old, how old is Liza?

Answers

Answer:

17 years old.

Step-by-step explanation:

sisters age:5

5×3+2=17.

Answer:

Liza is 17 years old.

Step-by-step explanation:

Ley 'x' be the age of Liza's younger sister

As Liza’s age is two more than thrice the age of her younger sister

so the equation of Liza's age will be:

Liza's age = 3x+2

As x = 5 years is Liza's younger sister age

so

Liza's age = 3(5)+2

                 = 15+2

                  = 17 years

Therefore, Liza is 17 years old.
