14×7%=.98 so then add the .98 to the 14 to get $14.98 if you don't have a percent sign on a calculator use .07 instead of 7% ( you will get same answer)
Answer: 160
Step-by-step explanation:
So first you start by making the percent which is 20 a decimal (.20) . Then , you multiplu .20 by 800 and get 160 , or if you know 10% is 80 2 times that would be 20 percent . And 80 plus 80 is 160 .
To find the area of the circle with diameter = 18 cm
We will use the formula:

where r= radius of the circle
From the quesion diameter = 18 cm
radius = diameter/2
radius = 18cm/2 = 9 cm
substituting r = 9cm into the formula


The above answer is when we are to leave the answer in terms of π
Otherwise if π is given to be 3.14 or 22/7 , we will simply substitute into the formula
That is given that π= 3.14
Answer:
∠ABD ≅ ∠CBD
Step-by-step explanation:
<u>Given: </u>line segment AB ≅ line segment BC
<u>Prove:</u> The base angles of an isosceles triangle are congruent.
Statement Reason
1. Segment BD is an angle bisector of ∠ABC - By construction
2. ∠ABD ≅ ∠CBD - Definition of an Angle Bisector
3. Segment BD ≅ segment BD - Reflexive Property
4. ΔABD ≅ ΔCBD - Side-Angle-Side (SAS) Postulate
5. ∠BAC ≅ ∠BCA - CPCTC
Answer:
see attachment
Step-by-step explanation:
It is convenient to use a spreadsheet for this purpose.
The first row of numbers is constant at $45, as there is no daily charge associated with that payment method.
The second row of numbers uses the formula ...
cost = $12 + $4×(number of days)
The third row of numbers uses the formula ...
cost = $6×(number of days)
___
Of course, you can use these formulas to fill in the numbers by hand. For example, for 15 days, the charges are ...
- Early Pay: $45 (no calculation necessary)
- Deposit Plus: $12 + $4×15 = $12 +60 = $72
- Daily Pay: $6×15 = $90
