Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)
= 180°-134°
= 46°
x= 46°
Part B:
120°
10. Find which one of the given fractions are value closer to 1.
First = 7/8
Second = 11/10
Let’s start solving
Let us start with the first value which is 7/8
=> 7 needs to be divided with 8
=> 7 / 8 = 0.875
Now, let’s solve the second value which is 11/10
=> same with first solution., divide 11 by 10
=> 11 / 10
=> 1.1
Thus, 11/10 is the has the nearest value to 1.
Answer:
$25.66
Step-by-step explanation:
Given data
Total Bill before tax and tip= $27.30
Tax= 9%
Tip= 15%
Let us find the tax
=9/100*27.30
=0.09*27.30
=$2.457
Let us find the tip
=15/100*27.30
=0.15*27.30
=$4.095
Therefore his bill after tax and tip is
=27.30+2.457-4.095
=$25.66
C is the answer, just plug every single answer option into the equation and solve each one then u could find the answer
Answer:
See below
Step.-by-step explanation:
Choice A has first term -3 and common difference 5. The formula for the kth term is -3 + (k - 1)5. It is an arithmetic series.
The required expanded form for the Sum is:
5
S5 = ∑ [-3 + (k - )5)]
k = 1
