The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)
Answer:
see below
Step-by-step explanation:
A) 12
B) 2
C)total number of brothers: 16 + 30 + 21 + 36 = 103 103 / 50 = 2.06
Let f(x) be y so you have
y=7x-13
Reverse the signs of x and y so you have
x=7y-13
And then find the value of y
x+13=7y
(x+13)/7=y
And change y to f(x)-1
<span>a) Visual Rhetoric. Logos means creating a symbol for some fixed thing. Pathos is related to evoking pity or sadness. Both these are clearly can't be the answer. Visual Rhetoric means using visual images to communicate meaning. This includes using visual design to make an argument. So this should be the answer.</span>
Bao saved 179 dollars a
month
Ada saved 145 dollars more than Bao a month
Let B = Bao
let A = Ada
=> B = 179 dollars
=> A = b + 145 dollars or 179 + 145
Now, find the total amount will ada save in 3 years and half
=> 3 years and half = (12 x 3) + 6 = 42 months
=> A = 179 + 145 x 42
=> a = 324 x 42
=> A = 13 608 dollars in 3 years and half.
