A search and rescue drone can scan 0.5 hectare in 2 minutes. How many hectares per minute can the drone scan? 5/10 ha | 2 min = 5/10×2/1 yes or no
Answer:
Drone will take 0.25 hectare per minute to scan the area.
Step-by-step explanation:
By using unitary method,
A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.
Area scanned by the drone in 1 minute = [tex]\frac{\text{Total area scanned}}{\text{Total time taken}}[/tex]
= [tex]\frac{0.5}{2}[/tex]
= 0.25 hectare per minute
Therefore, drone will take 0.25 hectare per minute to scan the area.

Answer:
x = 15
Step-by-step explanation:
x + 2y = 37
x - y = 4
x + 2y = 37
2x - 2y = 8
3x = 45
x = 15
Find the solution set of the inequality
8x−8≤−72.
Answer:
x≤-8
Step-by-step explanation:
When solving 8x-8≤-72, first add 8 to both sides of the inequality.
This leaves you with 8x≤-64.
Divide both sides by 8: 8x/8 and -64/8
This leaves you with x≤-8 as your solution.
At Bike Shop X it costs $2.75 per hour plus a $3.00 deposit to rent a bike. At Bike Shop Z
it costs $1.75 per hour plus a $7 deposit to rent a bike. When would it cost less to rent a bike
from Bike Shop X? Explain.
Answer:
ok so you see that right away bike shop x is more cost than bike shop z so if you add 2.75 and 3 dollars it would cost 5.75 dollars of course the cost of 2.75 dollars is per hour so you would need to count 2.75 per hour and as you bike shop z the amount of cost per hour is 1.75 but the deposit fee is 7 dollars so the cost would be 8.75.
Step-by-step explanation:
Ok why it is lower cost because as you see each hour on shop x it is 2.75 and each hour in z shop it is 1.75 why z shop is lower because x shop have bigger cost per hour and that can add up more than z shop.

The CB radio of a trucker covers the circular area of (7,4). Find the equation of that circle. Give your answer in both standard and general form.
Answer:
Standard form is - (x - 7)² + (y - 4)² = 5²
General form is - x² + y² - 14x - 8y + 40 = 0
Step-by-step explanation:
Given - The CB radio of a trucker covers the circular area of (7,4).
Find the equation of that circle.
To find - Find the equation of that circle. Give your answer in both
standard and general form.
Proof -
Given that,
Center of CB radio = (7, 4)
Point on the Boundary = (10, 0)
Now,
We know that radius, r is
r = [tex]\sqrt{(7-10)^{2} + (4-0)^{2} }[/tex]
= [tex]\sqrt{(-3)^{2} + 4^{2} }[/tex]
= [tex]\sqrt{9 + 16}[/tex]
= [tex]\sqrt{25} = 5[/tex]
⇒r = 5
∴ we get
Standard form is - (x - 7)² + (y - 4)² = 5²
General form is -
x² + 7² - 2·7·x + y² + 4² - 2·4·y = 25
⇒x² + 49 - 14x + y² + 16 - 8y = 25
⇒x² + 65 - 14x + y² - 8y = 25
⇒x² + 65 - 14x + y² - 8y - 25 = 0
⇒x² - 14x + y² - 8y + 40 = 0
So, the general form is -
x² + y² - 14x - 8y + 40 = 0
sin x =
cos x =
tan x =
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
so Sin(x) = d/f
Cos(x) = e/f
Tan(x) = d/e
got it? :)
Answer: sin= d/f
cos= e/f
tan= d/e

−2a3+9a2+45a+6ab2+18b2
−2a3+21a2+45a+6ab2+18b2
Answer:
-2a³ + 9a² + 6ab² + 45a + 18b²Step-by-step explanation:
(a + 3)×(−2a² + 15a + 6b²) =
= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =

The product [tex](a+3) * (-2a^2+15a+6b^2)[/tex] is [tex]-2a^3+9a^2+ 45a +6ab^2 + 18b^2[/tex]
What is product?The product of numbers or expressions is gotten by multiplying them
The product expression is represented as:
[tex](a+3) * (-2a^2+15a+6b^2)[/tex]
Expand the expression
[tex]-2a^3+15a^2+6ab^2 -6a^2 + 45a + 18b^2[/tex]
Collect like terms

82% of what number is 492?
answer
600
Step-by-step explanation:
Step 1: If 82% of a number is 492, then what is 100% of that number? Setup the equation.
492/82%=Y/100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
82Y = 492 x 100
82Y = 49200
Y=49200100=600

4) A dozen cookies cost $18.75. Twenty cookies cost $25.50. Which has the lower unit price?
ROUND YOUR ANSWER TO THE NEAREST HUNDREDTHS. *
Answer:
Twenty cookies deal
Step-by-step explanation:
A dozen cookies cost 18.75. A dozen is exactly 12. If you divide 18.75 by 12 you should get the unit price which is about $1.56 for each cookie. For 25.50 you just divide it by 20 and you should get about 1.20 which makes it a better deal.
Find the distance d between 21 = (-7 - 6i) and Z2 = (-15 – 12i). Express your answer in exact terms and simplify, if needed.
Answer:
10
Step-by-step explanation:
The distance is equal to the modulus of Z1-Z2.
[tex]Z_1 - Z_2 = -7 - 6i - (-15 - 12i) = 8 + 6i\\|8 + 6i| = \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10[/tex]
