The school is selling potted plants as a fundraiser.Kara sold 12 ferns and 8 ivy plants for $260.Paul sold 15 ivy plants and 6 f
vovangra [49]

x=ferns ; y=ivy

12x+8y=260

6x+15y=240

x=60 -(15/6)y

12(60+ (15/6)y + 8y = 260

x=60 -(15/6)y

720 - 30y + 8y = 260

x=60- (15/6)y

-30y +8y= 260-720 ==> -22y= -460

x=60 -(15/6)y

y= (-460)/(-22)= 20.9090909091

y=20.90

x=60 -(15/6)×20.90= 7.75

×(ferns)=7.75$

y(ivy)=20.90$

Find the area can i get the answer ASAP pls......................
sesenic [268]
For the problem on the left, the best way to solve is by splitting the shape into two. The smaller square at the top, and the larger rectangle at the bottom. To find the area of the top of the square you multiply base times height. In this case, you do 36*36, to get 1296. For the larger rectangle, you also do base times height, and calculate 60*36, to get 2160. The final step is to add 2160 to 1296. After adding, you should get the sum of 3456. Add the unit, and since we’re finding area, add squares. The answer is 3456 yards squared.

For the second problem, we can notice that the shape is a trapezoid. The way we find the area of a trapezoid is by taking the average of the bottom length and the top length, and multiply it by the height. The first step is to do 16+8 to get 24. Next, you need to divide 24 by 2 since you’re finding the average of the two numbers. Finally, to finish multiply the height by 12. In this case you do 16*12, to get 192 feet squared.



Answer to A: 3456 Yards Squared
Answer to B: 192 Feet Squared

What is the equation of a parabola with a focus (2,4) and directrix y = 0?
svet-max [94.6K]

Answer:

The equation of the parabola is (x-2)^2 =8(y-2)

Step-by-step explanation:

Given focus is (2,4) and the directrix is y=0 so the parabola axis is parallel to y- axis.

Focus is (α,β+a) and the directrix is of the form y = β-a

so given  focus is (2,4) compare (α,β+a)

                  here β+a = 4 and a=2 and β=2

now given directrix y = β-a = 2-2 = 0

now the general parabola is (x-α)^2 =4a(y-β) ...(1)

now substitute α =2 ,β=2 and a=2 above equation

The equation of the parabola is (x-2)^2 =8(y-2)

Don is digging a vegetable garden in his backyard. he wants the area of the garden to be 120 square feet. he also wants the leng
iragen [17]

the question does not present the options, but this does not interfere with the resolution

let

x-------> the length of the garden

y-------> the width of the garden

A-------> Area of the garden

we know that

A=x*y

A=120 ft²

for x=12 ft

120=12*y-----------------> y=10 ft

but

<span>the length of the garden to be more than 12 feet
so
</span>

x > 12 ft

therefore

y < 10 ft

Hence

the answer is

The width of the garden <span>must be less than 10 ft  (width < 10 ft)</span>
