The proof that is shown. Given: ΔMNQ is isosceles with base , and and bisect each other at S. Prove: Square M N Q R is shown wit

h point S in the middle. Lines are drawn from each point of the square to point S to form 4 triangles. We know that ΔMNQ is isosceles with base . So, by the definition of isosceles triangle. The base angles of the isosceles triangle, and , are congruent by the isosceles triangle theorem. It is also given that and bisect each other at S. Segments _______ are therefore congruent by the definition of bisector. Thus, by SAS. NS and QS NS and RS MS and RS MS and QS

Question 7 of 10
Mama L [17]

Answer:

B

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant is

Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real irrational roots

• If b² - 4ac > 0 and a perfect square then 2 real rational roots

• If b² - 4ac = 0 then 1 real double root

• If b² - 4ac < 0 then 2 complex roots

Given

x² + 3x - 7 = 0 ← in standard form

with a = 1, b = 3, c = - 7 , then

b² - 4ac

= 3² - (4 × 1 × - 7) = 9 + 28 = 37

Since b² - 4ac > 0 then 2 real irrational roots

Answer:

A=63.6 approximately

Step-by-step explanation:

P=14.28

p=1/4(2pi*r)

p=1/2pi*r

14.28=1/2pi*r

28.56=3.14*r

r=9...... approximately

A=1/4pi*r^2

A=0.25*3.14*81

A=63.6......approximately

A scale mode of a building is 8 in. by 12 in. The scale is 1 in:15 ft. What are the dimensions of the actual building? (*you nee
VikaD [51]

Answer:

120 ft by 180 ft

Step-by-step explanation:

If every inch is 15 feet multiply 8 inches by 15 and then 12 by 15 to get your dimensions

15 * 8 = 120

15 * 12 = 180

120 x 180 feet

Convert to inches if needed.

1440 inches by 2160 inches

Delicious77 [7]

Answer:

<h2> 3hours 55 minute</h2>

Step-by-step explanation:

Step one:

Given data

distance= 160miles

velocity = 3/4 miles per minutes

Step two:

Required:

time

we know that velocity is

v=distance/time

times= distance/velocity

time=160/3/4

time= 160*4/3

time=640/3

time=213.33333minuts

Time= 3hours 55 minute
