How would I find the difference of 7/8 - 1/3 ?

Lemur [1.5K]

Answer:

$\frac{13}{24}$

Step-by-step explanation:

We have two fractions and are being asked to subtract them.

7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.

So what is the LCM (Least Common Multiple) of 8 and 3?

24.

Therefore :

$\frac{7 * 3}{8 * 3} - \frac{1*8}{3*8}$

$\frac{21}{24} - \frac{8}{24}$

$\frac{13}{24}$

What is the value of the expression

Y_Kistochka [10]

Answer:

0.8

Step-by-step explanation:

We begin with the expression: $0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )$

First, we need to convert the fractions into decimals to make this easier.

$-\frac{3}{4}=-0.75$ and $-\frac{4}{5} =-0.8$

Once we have this, we can simplify it

$0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8$

What angle has the same sine value between 0-180? as Sin 24

Inessa05 [86]

Answer:

$Sin156$

Step-by-step explanation:

Given

$Sin24$

Required

Find equivalent between 0 to 180;

Let 24 be represented by $\theta$

So, $\theta = 24$

From Trigonometry ratios;

$Sin\theta = Sin(180 - \theta)$ where $0\leq \theta \leq 180$

Recall that $\theta = 24$

So, we have to substitute 24 for $\theta$ in the above expression.

This gives

$Sin24= Sin(180 - 24)$

Subtract 24 from 180

$Sin24= Sin156$

Hence, the equivalent of $Sin24$ is $Sin156$

8) Factor each sum or difference of cubes completely.<br> a. 8x3 + 27

ASHA 777 [7]

Answer:

$\large\boxed{(2x+3)(4x^2-6x+9)}$

Step-by-step explanation:

$8=2^3\\\\8x^3=2^3x^3=(2x)^3\\\\27=3^3\\\\8x^3+27=(2x)^3+3^3\qquad\text{use}\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\=(2x+3)\bigg((2x)^2-(2x)(3)+3^2\bigg)=(2x+3)(4x^2-6x+9)$

harina [27]

Undercoverage might lead to bias in this study due to the risk of collecting data from a small number of people who feel strongly about the research study in this scenario.

<h3>What is Undercoverage bias?</h3>

This refers to a type of sampling bias which occurs when the research population aren't adequately represented in the study.

This type of sampling involves getting data from a selected few people who may have the same opinion or view about the study which doesn't depict the true representation of the population.

This makes the study to be biased which is why undercoverage is usually avoided when conducting a research.
