You need 4/5 cups of strawberriers to make 1 pie how much cups will u need to make 2 pies
Annette [7]

Answer:

1 \frac{3}{5} cups of strawberries

Step-by-step explanation:

To find how much you will need for 2 pies, multiply 4/5 by 2:

4/5(2)

= 8/5

Simplify this to a mixed number:

= 1 \frac{3}{5}

So, you will need 1 \frac{3}{5} cups of strawberries to make 2 pies

A and B are two cylinders that are mathematically similar.
Alik [6]

Answer:

Volume is 718 cm^3

Step-by-step explanation:

We need to get the radius of cylinder A

From the base area,

we have that;

A = pi * r^2

18 = 3.142 * r^2

r^2 = 18/3.142

r^2 = 5.73

r= √5.73

r = 2.39

If two shapes are similar, we have the ratio of their corresponding sides equal;

Thus;

2.39/5 = x/10

x = (10 * 2.39)/5

x = 4.78 cm

To get the volume, we use the formula

V = pi * r^2 * h

V = 3.142 * 4.78^2 * 10

V = 717.8 cm^3

This is approximately 718 cm^3

WILL MARK BRAINIEST!!1 PLZ HELP!25 points!!! The coordinate grid shows points A through K. What point is a solution to the syste
marishachu [46]

Answer:

A, C, D and K

Step-by-step explanation:

Inequalities:

y ≤ −2x + 10  and  y >1/2x-2

<u>Finding zeros for the first inequality:</u>

  • x=0 ⇒ y= 10, point (0, 10)
  • y=0 ⇒ x= 5, point (5, 0)
  • Locating these 2 points and connecting to get the first line.

Space to the left of this line (as y≤ ) is the solution for this inequality, any points on this line are inclusive.

<u>Finding zeros for the second inequality:</u>

  • x=0 ⇒ y= -2, point (0, -2)
  • y= 0 ⇒ x= 4, point (4, 0)
  • Locating these points and connecting to get the second line.

Space above this line (as y > sign) is the solution for this inequality, any points on this line are not inclusive.

Now we have the space of intersection of the above inequalities.

So the points in same section are the solution.

They are:

  • Points A, C, D and K

See attached for explanation
