What percentage of the actual salary are the actual total expenses?
Setler79 [48]

Answer:

95.97%

Step-by-step explanation:

Observing the table we have

The actual salary is $3,600 -----> This amount represent the 100%

The actual total expenses are $3,455

using proportion

Find out what percentage of the actual salary are the actual total expenses

\frac{100}{3,600}=\frac{x}{3,455}\\ \\ x=100*3,455/3,600\\ \\ x=95.97\%

Plz help me ASAP it’s important
Hunter-Best [27]

Answer:

D. 6.3

Step-by-step explanation:

Well you can make a triangle with the line PQ with it's height as 2 and base as 6.

Then you can use the Pythagorean Theorem to find the length of PQ.

a²+b²=c²

2²+6²=c²

4+36=c²

40=c²

c²=40

<em>Square root both sides</em>

c=\sqrt{40}

c≈6.3

Our answer is D. 6.3

What is Three-fourths divided by one-half? A fraction bar labeled 1. Under the 1 are 4 boxes containing one-fourth. Under the 4
Feliz [49]

Answer: Three-fourths divided by one-half is <u><em>one and a half.</em></u>

Step-by-step explanation:

Here we need to find,  Three-fourths divided by one-half.

i.e. To find : \dfrac 34 \div \dfrac 12

Since , \dfrac{a}{b}\div\dfrac{c}{d}= \dfrac{a}{b}\times\dfrac{d}{c}

So, \dfrac 34 \div \dfrac 12=\dfrac{3}4\times\dfrac{2}1

=\dfrac{3}{2}\times\dfrac11[Cancel 4 by 2 and it remains as 2.]

=\dfrac{3}{2}=1\dfrac{1}{2}

Hence,  Three-fourths divided by one-half is <u><em>one and a half.</em></u>

Which equation represents the transformed function below? on a coordinate plane, a parent function starts at (0, negative 1) and
pishuonlain [190]

The parent function which starts at (0, -1) and then curves up into quadrant 1 is logx and the transformed function which starts at (0, 4) and then curves up into quadrant 1 is logx+5.

<h3>What is transformation of a function?</h3>

Transformation of a function is shifting the function from its original place in the graph.

Types of transformation-

  • Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.
  • Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.

On a coordinate plane, a parent function starts at (0, -1) and then curves up into quadrant 1 and approaches y = 1. Thus, the function of this curve is,

y=logx

A transformed function starts at (0, 4) and then curves up into quadrant 1 and approaches y = 6.

y=logx +5

Thus, the parent function which starts at (0, -1) and then curves up into quadrant 1 is logx and the transformed function which starts at (0, 4) and then curves up into quadrant 1 is logx+5.
