Answer:
this seems hard to do
Step-by-step explanation:
The answer is diameter: 32 in, area: 64 in²
The perimeter of a sector of a circle is:
P = 2r + l
l = r<span>θ
P = 2r + r</span>θ<span>
P = 32 in
32 = 2r + r</span><span>θ
</span>32 - 2r = r<span>θ
</span>θ = (32 - 2r)/r
θ = (2*16 - 2*r)/r
θ = 2(16 - r)/r<span>
Area of the sector of the circle is:
A = r</span>²/2 * θ
A = r²/2 * 2(16 - r)/r
A = r² * (16 - r)/r
A = r(16 - r)
A = 16r - r²
For the maximum area:
A' = 16 - 2r
A' = 0
16 - 2r = 0
16 = 2r
r = 8 in
The diameter (D) of the circle is twice of the radius:
D = 2r = 2 * 8 = 16 in
The maximum area is:
A = 16r - r²
r = 8 in
A = 16 * 8 - 8²
A = 128 - 64
A = 64 in²
Answer:
320 g flour
8 g salt
12 g yeast
20 ml oil
Step-by-step explanation:
To get from 600 to 400, divide by 1.5
To find the amounts of the other ingredients she will use, divide by 1.5
480/1.5 = 320 g flour
12/1.5 = 8 g salt
18/1.5 = 12 g yeast
30/1.5 = 20 ml oil
Answer:
x=8
Step-by-step explanation:
x=24/3
therefore, the answer is x=8
Answer:
The sales tax is 0.26 dollars. The total amount is $3.76.
Step-by-step explanation:
To find, how much you will need to pay for sales tax, multiply 0.075 with 3.5; you get about 0.26. Add that to 3.50 and you get 3.76. If this helps please rank Brainliest. Thanks!
