For this case we have that the complete question is:

A spider ate 25% more bugs this month than last month. The spider ate 8 bugs last month. How many bugs did the spider eat this month?

So, we propose a rule of three:

8 bugs -----------> 100%

x -----------------------> 25%

Where the variable "x" represents the number of bugs equivalent to 25%.

x = \frac {25 * 8} {100}\\x = 2

Thus, 2 bugs represent 25%

If this month the spider ate 25% more, then it ate:

8 + 2 = 10

Answer:

This month, the spider ate 10 bugs

Answer:

<em>La araña comió 10 bichos este mes.</em>

Step-by-step explanation:

<u>Porcentajes</u>

Este es un problema simple de aplicación de porcentajes sumativos. También se puede resolver por regla de tres o por proporciones. Lo haremos de manera lógica paso a paso.

El problema no indica una pregunta específica, por lo que asumiremos que la pregunta requiere calcular cuántos bichos comió la araña este mes.

La araña comió este mes 25% mas bichos que el mes pasado. Conociendo que el mes pasado comió 8 bichos, entonces

25% de 8 = 0.25*8=2

Este mes comió 2 bichos más que el mes pasado, lo que significa que en total comió

8+2=10 bichos este mes.

The heights of women aged 20 – 29 in the United States are approximately Normal with mean 64.2 inches and standard deviation 2.8
Bumek [7]

Answer: 0.64

Step-by-step explanation:

Given : The heights of women aged 20 – 29 in the United States are approximately Normal with \mu=64.2 inches and \sigma=2.8 inches.

Let x denotes the height of women.

Since 1 feet = 12 inches

5.5 feet = 5.5\times12=66 inches

Then, the z-score corresponds to x=66 inches will be :-

z=\dfrac{66-64.2}{2.8}=0.642857142857\approx0.64

Hence, the z ‑score for a woman 5.5 feet tall = 0.64

Suppose sarah is trying to design a metal box (a rectangular prism), which will hold 200 cubic centimeters of liquid. the length
xxTIMURxx [149]
Volume = length * width * height = lwh (measured in cubic units)
so 2000 cm^3 = lwh
we know that l = 4w so sub that into the equation
2000 = (4w)*w*h
2000 = 4w^2*h

You didn't include the rest of the question so this is as far as i can go.
