Answer:

76%

Step-by-step explanation:

Start with the fraction $\frac{19}{25}$
Get the denominator to 100 by multiplying both the numerator ad denominator by 4

This will give you the fraction $\frac{76}{100}$
This can be turned into 76%

Approximately how much larger is the population of Pennsylvania than the population of Ohio? Pennsylvania's population is 12,604

nadya68 [22]

Answer= 1 million

For an approximation we don't use exact numbers. Seeing as Pennsylvania has a population of around 12.6 million and Ohio has a population near 11.5 million, there is about a difference of 1 million when comparing the populations.

Whats the answer to x^3 y^0 z^-2

Elina [12.6K]

Answer:

$\frac{x^3}{z^2}$

Step-by-step explanation:

There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.

As we all know that any variable or number to the power of 0 is equal to 1. This means that $y^0 = 1$ .

We also know that a negative power can bring the variable down and make it a fraction. This means that $z^-^2=\frac{1}{z^2}$

Now that we got these two sorted we are able to write it in a simplified form.

Answer: $\frac{x^3}{z^2}$

Determine the number of possible triangles, ABC, that can be formed given angle A = 30°, a = 4, and b = 6.

Sophie [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

using Sine Law,

$\frac{sinA}{a}=\frac{sinB}{b}$

$\frac{sin30}{4}=\frac{sinB}{6}$

$sinB=0.75$

$angle B = 48.6$

Another angle will be

$angle B' = 180-48.6 = 131.4$

considering angle B, angle C = $180 - (48.6+30)=101.4$

considering angle B', angle C' = $180-(131.4+30)=18.6$

$\frac{sinA}{a}=\frac{sinC}{c}$

$\frac{sin30}{4}=\frac{sin101.4}{c}$

$c = 7.84$

Similarly, finding c'

$\frac{sinA}{a}=\frac{sinC'}{c'}$

$\frac{sin30}{4}=\frac{sin18.6}{c'}$

$c'=2.55$

Hence two triangles are possible with below details: : Answer

A = 30, B = 48.6, C = 101.4, c = 7.84

A = 30, B' = 131.4, C' = 18.6, c' = 2.55

Hope it will help :)

The first graph is linear and the 2nd one is nonlinear
the first table goes for linear and the 2nd table goes for nonlinear :)
