Answer: .80

Step-by-step explanation: When we take the number 1 as a whole and divide it by 5 it equals .20. Or take 100 as the whole and divided by 5 is 20 Now you want 4 out of the 5 sections, and each section is .2 or 20, so you multiply that by 4 and for 4/5 the decimal is .80

dusya [7]

Answer:

6% decline

Step-by-step explanation:

Original stock price = $3.63 + $56.87 = $60.50

Percentage decline = 60.50 - 56.87 / 60.50

= 3.63 / 60.50

= 0.06

= 6% decline

Given the following coordinates complete the reflection transformation. A(1,−5) B(2,−2) C(5,−2) Transformation: Complete the dou

Dmitriy789 [7]

Answer:

A''(1,-1) B''(2,2) C''(5,2)

Step-by-step explanation:

Points A(1,−5) B(2,−2) C(5,−2)

reflection over y=-1

Perpendicular distance between points y-coordinates of points (A, B and C) and y=-1 are 4,1 and 1

after reflections, the perpendicular distance will be 8,2,2 and the points will be at

A'(1,3) B'(2,0) C'(5,0)

again reflection over y=1

Perpendicular distance between points y-coordinates of points (A', B' and C') and y=1 are 2,1 and 1

after reflections, the perpendicular distance will be 4,2,2 and the points will be at

A''(1,-1) B''(2,2) C''(5,2)!

Find the missing side of the triangle.

lys-0071 [83]

Answer:

x=√40

Step-by-step explanation:

In above figure,

h=7

b=3

p=x=?

Now,

by Pythagoras theorem,

$p = \sqrt{ {h }^{2} - {b}^{2} } \\ = \sqrt{ {7}^{2} - {3}^{2} } \\ = \sqrt{49 - 9} \\ = \sqrt{40}$

In the diagram, how many angles are alternate exterior angles with angle 5?

Natasha_Volkova [10]

Answer:

Angle 11 is the alternate exterior of angle 5 meaning there is only 1 angle that is alternate of angle 5.

Step-by-step explanation:

An exterior angle is an angle outside of the shape (hence ex meaning out). However, an ALTERNATE angle is an angle opposite of a transversal line of another angle. The angles on the same transversal line of 5 are 8, 7, 9, 10, 12, and 11. However, we are looking for ALTERNATE EXTERIOR angles not just exterior. 8, 7, 9, 10, and 12 are just exterior which leaves angle 11 as alternate exterior. Angle 11 is the alternate exterior of angle 5 meaning there is only 1 angle that is alternate of angle 5.
