Seth has a garden with dimensions 9 feet long times 8 feet wide he wants to enlarge the garden to an area of 120 ft.² how much f

ziro4ka [17]

Answer:

6 ft longer (total length of 15ft)

Step-by-step explanation:

the initial dimensions are:

length: $l=9ft$

width: $w=8ft$

the area area of the garden is given by:

$a=l*w$

so the original area is:

$a=9ft*8ft=72ft^2$

Since we need the area to be $120ft^2$ , and we can only change the length, the width will still be 8ft.

We substitute the value of the new area and the width to the equation for the area:

$a=l*w\\120ft^2=l*8ft$

and we clear for the new length:

$l=\frac{120ft^2}{8ft}\\ \\l=15$

The length of the garden for the area to be $120ft^2$ , must be 15ft.

This means that if originally the length was 9 ft, now it has to be 6 ft longer.

Answer:

$\large\boxed{Q1.\ \sin\theta=\dfrac{40}{41}}\\\boxed{Q2.\ 30^o}$

Step-by-step explanation:

Q1.

$\sin\theta=\dfrac{y}{r}$

$\text{We have}\\\\r=1\to(\text{radius of the unit circle}),\\\\y=\dfrac{40}{41}\to\text{from the given point}\ \left(\dfrac{9}{41},\ \dfrac{40}{41}\right)\\\\\text{Substitute:}\\\\\sin\theta=\dfrac{\frac{40}{41}}{1}=\dfrac{40}{41}$

Q2.

A cylinder with a 2 centimeter diameter is drilled through the triangular prism shown on the left find the volume of the prism

saw5 [17]

Answer:

The volume of a prism on its own = 248.5cm^3

The volume of a cylinder = 87.92cm^3

Step-by-step explanation:

The volume does not change for the prism as the hole was drilled.

We can show the drilled space with v(l) and (p) for prism V

v(l) 248.5p - 87.92p + 87.92p

= 248.5p
