8 0

Answer:

18 cm for larger base

Step-by-step explanation:

For similar figures, there is a formula regarding volume, area, and length

Large: small =  y: x   for length

large: small = (y^3) / (x^3)  for volume

729 cm cube/ 64 cm cube  = large : small

9: 4  = large: small  by length

large/ 8cm = 9/ 4

large = 8*(9/4) = 2*9 = 18 cm

These too please i’ll cry if i don’t figure this out
sammy [17]

Answer:

PO = 11, LQ = 4, NQ = 12, perimeter of NLP = 24

Step-by-step explanation:

The centroid is the point where the medians intersect each other.

A median divides the side it intersects in 2 equal parts.

So, if NP = 11, then PO = 11

The medians of a triangle intersect each other in the ratio 2:1

So, if NL = 8, then LQ = 4 and NQ = 8+4 = 12

if ML = 10, LP = 5

Finally, the perimeter of the triangle NLP is

NL + NP + LP = 8 + 11 + 5 = 24

Ms. Ciervo is making cupcakes. She has 9 2/3 teaspoons of vanilla. Each cupcake needs to have -1/3 teaspoon of vanilla. How many
Artist 52 [7]

Answer:

The number cupcakes Ms. Ciervo can make using the 9 \frac{2}{3} teaspoons of vanilla is 29.

Step-by-step explanation:

The information provided is:

  • Ms. Ciervo has 9 \frac{2}{3} teaspoons of vanilla.
  • Each cupcake needs to have \frac{1}{3} teaspoon of vanilla.

Compute the number cupcakes Ms. Ciervo can make using the 9 \frac{2}{3} teaspoons of vanilla as follows:

Amount of vanilla required for one cupcake = \frac{1}{3} teaspoons

Total amount of vanilla available 9 \frac{2}{3} teaspoons.

\text{number of cupcakes}=\frac{\text{total amount}}{\text{amount required for 1 cupcake}}

                               =\frac{9\frac{2}{3}}{\frac{1}{3}}\\\\=\frac{29}{3}\div\frac{1}{3}\\\\=\frac{29}{3}\times \frac{3}{1}\\\\=29

Thus, the number cupcakes Ms. Ciervo can make using the 9 \frac{2}{3} teaspoons of vanilla is 29.
