Danny has a rectangular rose garden that measures 8m by 12.5m. One bag of fertilizer can cover 16m2 . How many bags will he need
mrs_skeptik [129]

Answer:

we will need 7 bags

Step-by-step explanation:

To solve this problem we first have to calculate the total area of ​​the garden

a = area

b = base = 8m

h = height = 12.5m

a = b * h

we replace with the known values

a = 8m * 12.5m

a = 100m²

Now that we know the total area of ​​the garden and the area occupied by a single bag, we divide the total area by what a bag covers.

100m² / 16m² = 6.25 bags

because we cannot buy a fraction of a bag we will need 7 bags

90 POINTS WILL GIVE BRAINLIEST for which value of theta is cot theta equal to cos theta
Angelina_Jolie [31]

Answer:

...so cos t = cot t can only happen when cos t is 0 or sin t is 1. (But sin t = 1 only happens when cos t = 0, so cos t = 0 is enough.)  

arccos(0) is pi/2, plus or minus any multiple of pi.

Step-by-step explanation:

 

cotθ = cosθ  

cosθ/sinθ = cosθ  

sinθ = 1  

θ = π/2

pi also = to 3.14 etc.

Step-by-step explanation:

the real equation is:

y = 2x + 0 which is the same as y = 2x.

Equation for 2:

y = 1x + 2.

Equation for 3:

y = 2
