Step-by-step explanation:
just think about the basic formulas for area and perimeter of rectangles, and what pieces of information we already have directly.
area = length × width
perimeter = 2×length + 2×width = 136 m
=> length + width = 68 m
then we know
length = 2×width + 8
this we use as substitute in the simplified perimeter equation :
2×width + 8 + width = 68
3×width + 8 = 68
3×width = 60
width = 20 m
and therefore
length = 2×width + 8 = 2×20 + 8 = 40+8 = 48 m
and now we can calculate the area :
area = length×width = 48×20 = 960 m²
please consider that for a length or distance we use m (or other length units), for and area then m². for a volume then m³. as a basic unit for an area is a square. and for a volume a cube.

Find the measure of an angle whose complement is five times its measure.
The measure of the angle is?
Answers
Answer:
The measure of the unknown angle is 15°.
Step-by-step explanation:
Represent this angle by A. Then the complement of A is 90° - A.
"Angle whose complement is five times its measure" would be expressed as
90° - A = 5A
Solve this for A by adding A to both sides:
90° = 6A. Then A = 90°/6, or 15°

(3x - y) cm
(2x – 3) cm
(2x + y) cm
Answers
Answer:
875cm^2
Step-by-step explanation:
since opposite sides are equal
3x-y=2x+y
x=2y
y=x/2 ....(i)
thus new length=2x+y
=2x+(x/2) [using (i)]
=(4x+x)/2
l=5x/2 .....(ii)
now,
perimeter=2(l+b)=120cm
l+b=60cm
from figure and using (ii)
[5x/2]+2x-3=60
[5x+4x-6]/2=60
9x-6=120
9x=126
x=126/9
x=14 ..........(iii)
substitute (iii) in (i)
y=14/2
y=7 ...........(iv)
From figure,
length=2x+y [using (iii) and (iv)]
=2x14+7
length=35cm
breadth=2x-3
=2x14-3 ....[using(iii)]
=28-3
breadth=25cm
now,
Area=lxb
=35x25
=875cm^2

i think 2nd one is true....f(-2)=g(-2)
Answer:
A is correct: [tex]f(0)=g(0)[/tex]
Step-by-step explanation:
To find this answer, we first must identify what [tex]f(x)[/tex] and [tex]g(x)[/tex] means.
[tex]f(x)[/tex] shows the y value of the line at the specified x value.
[tex]g(x)[/tex] shows the y value of the line at the specified x value.
So in order to solve this problem, we must look at each of the options and see which one is true.
If we take a look at the first option...
[tex]f(0)=-2[/tex] in this example and [tex]g(0)=-2[/tex] as well.
[tex]-2=-2[/tex] and therefore, option A is correct.

Answer:x =6
Answer:x =6Step-by-step explanation:
Angle in a triangle is 180
75+ (7x+14) +49 =180
75+ 49+ (7x+14)= 180
124+ (7x+ 14) = 180
124+ 14 +7x= 180
138+7x = 180
7x =180- 138

If you deposit $8000 into an account paying 7% annual interest compounded quarterly, how long until there is $12400 in the account?
The formula for deducing Compounded Annual Growth rate, CAGR = {( EV / SV)^1 / n} - 1
where:
EV = Investment's ending value
SV = Investment's starting value
n = Number of investment periods (months, years, etc.)
If you rearrange the formula for deducing the time period required.
SV = $8000
EV= $12400
Total appreciation = (EV-SV)*100%/SV = 64.52%.
At CAGR of 7%, the time required for any value to appreciate 64.52% is 6 years and 6 months

The rectangular base of the current enclosure has the length and width shown. Sierra decides to buy a larger enclosure that is a scale copy of the small one. The base of the new enclosure is 48 inches long. What is the perimeter of the new base?
Answers
Answer:
144in
Step-by-step explanation:
METHOD 1:
18 - 36
x - 48
36x = 18 * 48
36x = 864
x = 24
ALTERNATIVE METHOD:
18:36 (breadth:length)
1:2
When the length is 48in, the breadth is half the length, hence, the breadth is 24in.
Final Solution:
So, when the base is 48in, the width is 24in.
Since we have the two values
P = 2(l+b)
= 2(48+24)
= 2 * 72
= 144in

If a line has slope -4/3 and passes through the point (-3, 7), what is the y-intercept of the
line?
Answers
Answer:
y- intercept = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{4}{3}[/tex] , then
y = - [tex]\frac{4}{3}[/tex] x + c
To find c substitute (- 3, 7 ) into the equation
7 = - [tex]\frac{4}{3}[/tex] (- 3) + c
7 = 4 + c ⇒ c = 7 - 4 = 3 ← y- intercept
