Use a transformation to solve the equation. k/-4 = - 0.8

A.

k = –3.2

B.

k = –0.2

C.

k = 0.2

D.

k = 3.2

Answers

k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
   this means, (k/-4) x -4 = - 0.8 x -4
   this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
   so k= 3.2

your answer is D

Express 53 = x as a logarithmic equation.

Answers

Answer:

$\log_5 x = 3$

Step-by-step explanation:

Using logarithmic rule:

$\log_b b^a = a$

Given the equation:

$5^3 = x$

Taking log with base 5 both sides we have;

$\log_5 5^3 = \log_5 x$

Apply the logarithmic rule:

$3 = \log_5 x$

$\log_5 x = 3$

Therefore, $5^3 = x$ as a logarithmic equation is, $\log_5 x = 3$

log5x=3 I think is the answer

If ladybugs have 30 cm x 10 cm rectangles for pumpkins each pumpkin needs exactly 25 square centimeters of space how many pumpkins can they plant

Answers

To calculate how many pumpkins can be planted in a given space, you need to know the total area available and the area required for each pumpkin.

You mentioned that each pumpkin needs a rectangular space of 30 cm x 10 cm, which is an area of (30 cm) * (10 cm) = 300 square centimeters.

Now, if you have the total area available, you can divide it by the area required for each pumpkin:

Total Area Available / Area Required for Each Pumpkin = Number of Pumpkins

If you provide the total area available, I can help you calculate how many pumpkins can be planted.

Ans 12

Explaination
Area = 30*10cm= 300cm^2
Each pumpkin= 25cm^2
No. Of pumpkin that can be planted= 300/25= 12
