Alright I got one question what is 9+10

Whats the percent increase from 20 students to 30 students rounded to the nearest percent

yaroslaw [1]

Given Situation: What is the percent increase from the 20 students to the 30 students. Solution: => Let’s find how many percent did it increase. Let’s have 20 as the first total number of the students in the first counts. => Then it became 30 students, let’s find out how many students added. => 30 – 20 = 10, there are 10 students added 10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.

X-5For the function g(x) =solve the following inequality.7X+7g(x) > 0

iren2701 [21]

$g(x)=\frac{x-5}{x+7}$

We need to find the points x where

$\frac{x-5}{x+7}>0$

This can only happens if both, the numerator and the denominator have the same sign, that is

$\begin{gathered} x-5>0 \\ x>5 \\ \text{and} \\ x+7>0 \\ x>-7 \end{gathered}$

or

$\begin{gathered} x-5$

The first pair of inequalities leads to the set

$(5,\infty)\cap(-7,\infty)=(5,\infty)$

and the second

$(-\infty,5)\cap(-\infty,-7)=(-\infty,7)$

Then, the answer is

$(-\infty,-7)\cup(5,\infty)$

The coordinates of parallelogram PVWZ are P(0, 0), V(a, b), and Z(c, 0). Find the coordinates of W without using any new variabl

cupoosta [38]

Answer:

Co-ordinates of W must be (c+a,b).

Step-by-step explanation:

We are given that,

PVWZ is a parallelogram with vertices P(0,0), V(a,b) and Z(c,0).

Since, PVWZ is parallelogram.

The possible line segments are PV, VW, WZ and ZP.

Also, as the opposite sides must be parallel for the parallelogram, the co-ordinates will move accordingly.

So, we see from the figure that,

Co-ordinates of W must be (c+a,b).

Solve the formula for the variable h.<br> f= 5gh<br> h=[

Darya [45]

Given the formula, f = 5gh

To solve for h:

Factor out h from the right-hand side of the equation:

f = h(5g)

Divide both sides by (5g):

f /(5g) = h(5g)/(5g)

f/5g = h

A meteorologist forecasted that Monday's high temperature would be 76°F. On Monday,

goldenfox [79]

The percent error in the meteorologist's forecast for Monday is 5.26316 %

<h3><u>Solution:</u></h3>

Given that Monday's high temperature would be 76°F

On Monday, the temperature reached 80°F

To find: percent error in the meteorologist's forecast for Monday

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

<em><u>The percent error is given as:</u></em>

$\text {percent error }=\frac{\text {observed - standard}}{\text { standard value}} \times 100$
