Answer:
19 of 24
Step-by-step explanation:
in this case each question is 1 point, or a substitute variable, <em>a.</em>
<u>Additional requirements in figure</u> :-
Mark point :-
Draw a straight line from E to AB .
And the point line joins mark it as "F" .
It will generate quadrilateral FBCD.
we get to know In quadrilateral left angle is 90°
How ?
{
proof :
As three angles are given 90° So third angle will also be 90°
Reason:
→ Sum of interior angles = 2 (no. of angles - 2 × 180°
→Sum of interior angles = (4-2 × 180°)
→Sum of interior angles = (2 × 180°)
→Sum of interior angles = 360°
}
<u>✿</u><u>Now let the left angle be </u><u>x</u>
- 90° +90° + 90° + x = 360°
- 180° + 90° + x = 360°
- 270° + x = 360
- x = 360° - 270°
- x = 90°
<u>we know</u> :
Area of rectangle = Length × Breadth
STEPS :
- Area of rectangle = Length × Breadth
- Area of rectangle = 7 × 8
- Area of rectangle = 56 in²
<u>Now let's find EF</u> :
<u>To find A</u>
<u>F</u> :
<u>In triangle AFE</u>:
- EF is base of triangle
- A•F is height of triangle
We know :
<u>Area of triangle =(</u><u> </u><u>Height</u><u> </u><u>×</u><u> </u><u>Base)/2</u>
Steps :
- Area of triangle = (Height × Base)/2
- Area of triangle = (4 × 3)/2
- Area of triangle = 12/2
- Area of triangle = 6 in²
<u>To find area of figure</u> :
- Area of figure = Area of rectangle + Area of triangle
- Area of figure = 56 + 6
- Area of figure = 62 in²

Step-by-step explanation:
You will eliminate y because 3y-3y=0
Answer:
adult $13 student $15
Step-by-step explanation:
A=adult S = student
9A + 4S = 177
1A + 4S = 73
Multiply the second by (-1)
9A +4S = 177
-1A -4S = -73
ADD BOTH (4S will be cancelled)
8A = 104
A = 13 ( Adult ticket = $13)
13 + 4S = 73
4S = 60
S = 15 ( student ticket $15)
Answer:
$875.18
Step-by-step explanation:
Given data
Lydia
P=$5900
Interest rate=2 5/8% >>21/8= 2.625%
compounded monthly.
First, convert R percent to r a decimal
r = R/100
r = 2.625%/100
r = 0.02625 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 5,900.00(1 + 0.0021875/12)^(12)(19)
A = $ 9,710.01
Jace
P=$5900
Interest rate= 2 1/8% >>> 17/8>> 2.125%
Time= 19 years
First, convert R percent to r a decimal
r = R/100
r = 2.125%/100
r = 0.02125 per year,
Then, solve our equation for A
A = Pert
A = 5,900.00(2.71828)^(0.02125)(19)
A = $ 8,834.83
Hence the difference in their account balance is
= 9,710.01- 8,834.83
=$875.18
Therefore Lydia has $875.18 more money than Jace
