Your answer is 3/75 my friend, Hope i helped!!
Answer:
The ratio of the length of the banner to the length of the sign = 54/17
So....since they are similiar figures, the widths will have the same ratio
And the ratio of the area of the banner to the area of the sign will be the square of this ratio
Step-by-step explanation:
[54/17]^2 = 2916/289
Answer:
83422.5 grass seeds
Step-by-step explanation:
Applying,
A = 1/2bh....................... Equation 1
Where A = Area of the Triangle, b = base, h = height.
But, from the diagram,
tanФ = 20/b
b = 20/tanФ.................. Equation 2
Substitute equation 2 into equation 1
A = 1/2(20/tanФ)(h)................ Equation 3
Given: h = 20 m, Ф = 40°
Substitute these values into equation 3
A = 1/2(20×20)/tan40°
A = 200/tan40°
A = 238.35 m²
If the seed company recommends planting approximately 350 grass seeds per square meter,
Therefore,
Number of grass seed need = (350×238.35)
Number of grass seed needed = 83422.5 grass seeds
Answer:
B
Step-by-step explanation:
The square of y would look like y^2 and decreased means subtraction
So the equation now y^2-
the quotient of 8 and y would be 8/y
The full equation is y^2-8/y
