Answer:
Step-by-step explanation: First figure what’s in the parentheses. (3-2*2) wanna do 2*2 That’s 4 then (3-4) = -1. 2+(-1)*1. Then multiply -1 by 1 which is -1. Then 2+(-1)= 1
Answer:
The value of q is -2.7
Step-by-step explanation:
<h3><u>Given</u>;</h3>
N = m ÷ x + q
<h3><u>To</u><u> Find</u>;</h3>
q = ?
when,
N = 1⅘ = 9/5
m = 9
x = 2
Now,
N = m ÷ x + q
9/5 = 9/2 + q
q = 9/5 – 9/2
q = 1.8 – 4.5
q = -2.7
Thus, The value of q is -2.7

Answer:
a = -2 and b=4 and c = -4
Step-by-step explanation:
the center is : A(1 ; -2)
B(1 ; 1) in this circle so ; AB= r ( ridus)...r =3
note :
an equation of the circle Center at the A(1,-2) and ridus : r is :
(x-1)² +(y+2)² = 3²
x²-2x+1 +y²+4y +4-9 =0
x²+y² -2x+4y -4 = 0 so : a = -2 and b=4 and c = -4

Answer:
398.2 cm²
Step-by-step explanation:
The area of the whole circle is ...
A = πr²
A = π(13 cm)² = 169π cm²
The 270° sector is 3/4 of the whole circle, so its area is ...
sector area = (3/4)(169π cm²) ≈ 398.2 cm²
Answer:
4:12pm
Step-by-step explanation:
85 minutes = 1 hour and 25 minutes
2:47pm + 1 hour 25 minutes = 3:72 pm
72 minutes = 1 hour 12 minutes so add another 1 hour to 3 and the balance is 12 minutes so walk ends at 4:12pm
Another way to look at it is as follows:
After 13 minutes, the time is 2:47 + 0:13 = 3pm
Remaining time left is 85-13 = 72 minutes = 1 hour: 12 minutes. Add that to 3pm and you get 4:12pm
