$\\ \sf{:}\implies (side)^3=14$

$\\ \sf{:}\implies side=\sqrt[3]{14}$

$\\ \sf{:}\implies side=2.5in$

Now

L=11in
B=8in

$\\ \sf{:}\implies Area=11(8)=88in^2$

Cut it into 10 parts as per question(Open side means five sides hence it will be 5×2=10)

$\\ \sf{:}\implies 88/10=8.8in$

Now divide by previous side

$\\ \sf{:}\implies \dfrac{8.8}{2.5}=3.52=3.5$

When mushrooms are dried, they lose 80 percent of their mass. What weight of mushrooms must be picked to get 1 kg of dry mushroo

kaheart [24]

Answer:

We need to start with 5 kg of mushrooms

Step-by-step explanation:

The total of the dried mushrooms = mushrooms * percentage of weight kept

percentage of weight kept = 1- 80% = 20 %

We want 1 kg of dried mushrooms. Substitute in what we know

1 kg = mushrooms * 20%

1 kg = mushrooms * .2

Divide each side by .2

1 /.2 = mushroom *.2 /.2

5 kg = mushrooms

We need to start with 5 kg of mushrooms

Select the correct answer from each drop-down menu. The base of pyramid A is a rectangle with a length of 10 meters and a width

ASHA 777 [7]

Step-by-step explanation:

The formula of a volume of a pyramid:

$V=\dfrac{1}{3}BH$

B - base area

H - height

H - height of pyramids

Pyramid A:

$B=(10)(2)=200\ m^2$

$V_A=\dfrac{1}{3}(200)H=\dfrac{200}{3}H\ m^3$

Pyramid B:

$B=10^2=100\ m^2$

$V_B=\dfraC{1}{3}(100)H=\dfrac{100}{3}H\ m^3$

$V_A>V_B\\\\V_A=2V_B$

The volume of the pyramid A is twice as large as the volume of the pyramid B.

The new height of pyramid B: 2H

The new volume:

$V_{B'}=\dfrac{1}{3}(100)(2H)=\dfrac{200}{3}H\ m^3$

The volume of the pyramid A is equal to the volume of the pyramid B.

8x-2=-9+7x can you do it step by step

larisa [96]

In going to move constants to one side and variables to another by adding and subtracting.

8x -2 + 2 - 7x = -9 + 2 + 7x -7x

8x -7x = -9 + 2
Now solve

X = -7
