23. Eduardo wants to get a grade of 95 in his math

dem82 [27]

Answer:

105

Step-by-step explanation:

It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

(91+89+X)/3 =95

91+89+X =95*3

180+X =285

X =285 - 180

=105

-20÷5(-3)+4(-2)(-1)-4²<br>step by step please and thank you!

disa [49]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

$\large \tt \: -20 \div 5(-3)+4(-2)(-1)-4 ^ { 2 }$

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\tt \: -20 \div 5(-3)+4(-2)(-1)-4 ^ { 2 }$

Divide -20 by 5 to get -4.

$\tt \: -4\left(-3\right)+4\left(-2\right)\left(-1\right)-4^{2}$

Multiply -4 and -3 to get 12.

$\tt \: 12+4\left(-2\right)\left(-1\right)-4^{2}$

Multiply 4 and -2 to get -8.

$\tt \: 12-8\left(-1\right)-4^{2}$

Multiply -8 and -1 to get 8.

$\tt \: 12+8-4^{2}$

Add 12 and 8 to get 20.

$\tt \: 20-4^{2}$

Calculate 4 to the power of 2 and get 16.

$\tt \: 20-16$

Subtract 16 from 20 to get 4.

$= \boxed{\boxed{ \bf 4}}$

Find the distance between two points: (5,3),(8,5)

kozerog [31]

Answer:

$\displaystyle\boxed{\rm \: Distance= \underline{\underline{\sqrt{13}}}}$

<em>OR </em><em>in </em><em>Decimal</em>,

$\boxed{\rm \: Distance=\underline{\underline{3.605}}}$

Step-by-step explanation:

<u>Given:</u>

Two points, that is (5,3) & (8,5)

<u>To Find:</u>

The Distance of the two given points

<u>Solution:</u>

To Find the distance between two points, we will use the <u>distance</u> <u>formula</u>, i.e. :

$\boxed{ \rm \: Distance = \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} } }$

According to the Question,

$\rightarrow \: \rm \: x_2 = 8$

$\rightarrow \: \rm \: x_1 = 5$

$\rightarrow \: \rm \: y_2 = 5$

$\rightarrow \: \rm \: y_1 = 3$

Now Substitute the values on the formula of Distance and then Simplify:

$\rm \: Distance= \sqrt{(8 - 5 )^{2} + (5 - 3) {}^{2} }$

<em>[Follow PEMDAS rule while simplifying]</em>

$\rm \: Distance= \sqrt{3 {}^{2} + 2 {}^{2} }$

$\rm \: Distance= \sqrt{(3 \times 3) + (2 \times 2)}$

$\rm \: Distance= \sqrt{9 + 4}$

$\rm \: Distance= \sqrt{13}$

$\rm \: Distance= {3.605}$

Hence, the distance between the two given points would be $\sqrt{13}$ or $3.605$ .

$\rule{225pt}{2pt}$

I hope this helps!

Have a good day! :)
