Step-by-step explanation:

just trig :)

Step-by-step explanation:

s = side of square

l = length of rectangle = s + 3 cm

w = width of rectangle = s - 2 cm

s² + 30 = (s + 3)(s - 2) = s² + - 2s + 3s - 6 = s² + s - 6

30 = s - 6

s = 36 cm

B. 31.4 (pi) units

C. 31.4 units

A. 10 (pi)

Explanation:

Well since the equation to find circumference is C = 2(pi)r

And 10(pi) is exactly 2(pi)r, it’s not the answer.

And if we use 3.14 as an estimate for (pi), then 31.4 is also true for the circumference, because 10•3.14=31.4.

Also 10(pi) is more acurate then 31.4 because (pi) isnt exactly 3.14 its more like 3.1415926535...

The average rate of change of the function is of 5.44, which means that each day, there are 5.44 new cases on average.

The average rate of change of a function is given by the change in the output divided by the change in the input, that is, considering a function f(t) on an interval [a,b], the rate is:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

In this problem, the function which gives the number of flu patients after d days, [tex]0 \leq d \leq 21[/tex], is of:

[tex]f(t) = 10^{0.12d}[/tex]

Hence:

[tex]f(0) = 10^{0.12(0)} = 10[/tex]

[tex]f(21) = 10^{0.12(21)} = 124.3[/tex]

Then, the rate is:

[tex]R = \frac{124.3 - 10}{21 - 0} = 5.44[/tex]

The average rate of change of the function is of 5.44, which means that each day, there are 5.44 new cases on average.

Answer: 4.5 gallons

Step-by-step explanation:

Gallons of gas = # of miles / miles per gallon. Therefore:

153 miles/34 miles per gallon = 4.5 gallons

Answer:

4.5 gallons

Step-by-step explanation:

The car travelled 153 miles and gets 34 miles per gallon. So for every 34 miles it uses one gallon. 153 miles ÷ 34 miles per gallon = 4.5 gallons.

Answer:

y = -2.46 + 22.5606

Step-by-step explanation:

( - 6 , 11.61 ) , ( -5 , 9.15 )

m = ( 9.15 - 11.61 )/(-5--6)

m = -2.46

y - y1 = m( x - x1 )

y - - 6 = -2.46( x- 11.61 )

y = -2.46 + 22.5606

Step-by-step explanation:

The point (250,0) of the graph represents that the average price per ticket is $250.

Given to us

x is the price the passenger paid

f(x) is the positive percent difference

We know that a coordinate is written in the form of (x, y), therefore, the point (250, 0) represents that the price of the ticket is 250, while the 0 in the coordinate represents that there is no percentage difference. Since the point (250,0) is the mid-value of the x-axis on the graph, we can say that $250 is the average price of the ticket.

Hence, the point (250,0) of the graph represents that the average price per ticket is $250.

Answer:

A D E

Step-by-step explanation:

the figure shows that ABC is 90 degrees. So the two smaller angles add to 90 making A correct. (B isn't for obvious reasons - 180 is not 90.)

x + 4x - 85 = 90               Solve this to find the other 2 correct statements

5x - 85 = 90                    Add 85 to both sides.

5x = 90 + 85                    Combine

5x = 175                            Divide by 5

5x/5 = 175/5

x = 35

Since ABD is a single x, that statement (D) is true.

4x - 85 = 4*35 - 85 = 140 - 85 = 55 which makes E true as well

The tailor can make 8 outfits with 4 4/9 square yards of fabric

Given the following parameters;

A baby outfit uses 4/9 square yards of fabric for the hat and 1/9 square yards of fabric for the bib.

A tailor has 4 4/9 square yards of fabric, then the total outfit the tailor can make is expressed as:

total outfit = 40/9 ÷ 5/9

total outfit = 40/5

total outfit = 8 outfits

Hence the tailor can make 8 outfits with 4 4/9 square yards of fabric

Answer:  $1.73

=======================================

Explanation:

The simple interest formula is

i = P*r*t

that calculates the interest only

---------------

Let's calculate how much interest Lin will pay back if she goes with the 7 year loan at 4.5% simple interest rate.

i = P*r*t

i = 575*0.045*7

i = 181.125

i = 181.13

Repeat for the other loan (8 years, 3.9% simple interest)

i = P*r*t

i = 575*0.039*8

i = 179.40

Subtract the results

181.13 - 179.40 = 1.73

She saves $1.73 if she goes with the second loan.

The relationship between the time and the distance walked is an illustration of a linear equation.

From the table, we have the following equations:

The above equations mean that if time t increases by 1 second,

When time increases by 5 seconds, the rate is multiplied by 5

This means that:

The walking rate per minute is the unit rate or slopes of the linear equations.

So, the walking rates per minute are:
