Answer:

no

Step-by-step explanation:

no because if you multiply $329.50 by .6 you get $197.7, then with the additional 40% (.4) you end up having to pay $79.08

Answer:

{s | s < -8 or s >= -2}

Step-by-step explanation:

In order to solve an inequality we simply have to isolate the variable by applying the opposite operations on each side.

s - 2  <  -10   ... add 2 to both sides

s  <  -8

-3s  <=  6   ... divide both sides by -3, since we are dividing a negative number you must flip the sign

x >= -2

Therefore the final answer would be {s | s < -8 or s >= -2} which is the 3rd graphed multiple choice answer as seen attached to this answer.

Answer:

The average rate of change is two feet per second.

Step-by-step explanation:

The height of an arrow shot up into the air from a height of three feet is given by the function:

[tex]h(t)=-2t^2+12t+3[/tex]

And we want to find its average rate of change from one second the four seconds.

The average rate of change is synonymous with the slope. Therefore, we can evaluate the height of the arrow after the first and fourth seconds, and find the slope between them.

After the first second, the height of the arrow is:

[tex]h(1)=-2(1)^2+12(1)+3=13[/tex]

And after the fourth second, the height of the arrow is:

[tex]h(4)=-2(4)^2+12(4)+3=19[/tex]

This yields two points: (1, 13) and (4, 19).

The slope between them is:

[tex]\displaystyle m=\frac{19-13}{4-1}=\frac{6}{3}=2[/tex]

Therefore, the average rate of change from one second to four seconds is two feet per second.

Step-by-step explanation:

(375-6)÷9=369÷9=41

Answer: 41 students were on each bus.

Step-by-step explanation: Subtract the 6 students who traveled in cars from the total students (375 - 6 = 369). Then, divide the 369 students by the 9 buses and get your answer: 41 students per bus.

Answer:

2.5, 21/8, ³√25, π, √19

Step-by-step explanation:

The following data were obtained from the question:

³√25, π, 21/8, 2.5, √19

Next, we shall express each data as a decimal number where necessary. This can be obtained as follow:

³√25 = 2.9

π = 3.14

21/8 = 2.6

2.5 = 2.5

√19 = 4.4

Finally, we shall order the expression from least to greatest. This is illustrated below:

2.5, 21/8, ³√25, π, √19

Answer:

[tex]L = 6[/tex] --- Length

[tex]W = 4.5[/tex] --- Width

Step-by-step explanation:

Given

Let: [tex]L = Length; W = Width[/tex]

[tex]Area = 27m^2[/tex]

[tex]L = 2W- 3m[/tex]

Required

Find the dimensions of the rectangle

Area (A) is calculated as:

[tex]A = L * W[/tex]

This gives:

[tex]27 = (2W - 3) * W[/tex]

Open bracket

[tex]27 = 2W^2 - 3W[/tex]

Express as a quadratic function

[tex]2W^2 - 3W - 27 = 0[/tex]

Expand

[tex]2W^2 + 6W - 9W - 27 = 0[/tex]

Factorize:

[tex]2W(W + 3) - 9(W + 3) = 0[/tex]

[tex](2W - 9)(W + 3) = 0[/tex]

This gives:

[tex]2W - 9 = 0\ or\ W + 3 = 0[/tex]

[tex]2W = 9 \ or\ W = -3[/tex]

Width can not be negative.

So:

[tex]2W = 9[/tex]

[tex]W = 4.5[/tex]

Recall that:

[tex]L = 2W- 3m[/tex]

[tex]L = 2 * 4.5 - 3[/tex]

[tex]L = 6[/tex]

Answer:

C because to get y u do 180 - 57+61 than for x u do 180 - 62+67

Answer:

x=51

Step-by-step explanation:

y+57+61=180 linear pair

y=180-118=62

in triangle

x+y+67=180sum of interior angle of the triangle is 180

x+62+67=180

x=180-129=51

Answer:

side 1: 1.6

side 2: 2.3

side 3: 2.6

Step-by-step explanation:

side 1: 2x - 3

side 2: x

side 3: 2/3(x + 2x - 3) = 2x-2

(2x - 3) + x + (2x - 2) = 6.5

5x - 5 = 6.5

5x = 11.5

x = 2.3

side 1: 1.6

side 2: 2.3

side 3: 2.6

Answer:

45

Step-by-step explanation:

Because this is a triangle all angles must add up to 180. so we already know 90 so 180-90=90 and 90/2 = 45. Hope this helps

Step-by-step explanation:

1. Label each side of the Triangle

Using the SOH CAH TOA method we can label zy as H (the longest line is always H). We can label xz as O (it is opposite the angle). We can label xy as A (it's the remaining side).

2. Cross out the 'useless' side

Now, we need to cross out the label which doesn't have an appointed piece of information to it. Meaning that A will remain as it labels 7cm. H will also remain as it labels the angle. O does not label anything and so we can cross it out.

3. Decide which method is correct

We are using the SOH CAH TOA method, this means we can either use SOH, CAH, or TOA to solve the problem. We know which method to use by seeing which of them does not contain the letter we crossed out. CAH does not contain O so it is the correct method.

4. Know the formula

Now we will use the formula of our found method. CAH begins with C and so does Cos. Therefore, Cos is our formula.

Cos( ) = A/H

5. Substitute in your numbers

Then, we will put in our numbers into the formula. The first slot we must fill in is within the brackets. Usually the angle goes inside of the brackets during trigonometry but we obviously do not know it. This means we will use 'x' inside of the brackets. Our formula now looks like this:

Cos(x)

Substitute in A and H. A will be the information appointed to the side we labelled A. H will be the information appointed to the side we labelled H.

Our formula will look like this:

Cos(x) = 7/12

6. Reverse it and calculate

Now we need to input an equation into our calculator. I don't know why but we will need to reverse our previous formula and type it into the calculator as:

cos-^1(7/12)

The result should say 54.31466529.

7. Round

Now we will round it by 1 decimal place. To do this we need to look at the number next to 3, it is not 5 or above 5. This means we will not round up,

 our answer is 54.3 degrees.

Answer:

2/9

Step-by-step explanation:

Call the unknown number n

Therefore, we can express your question in the following manner

8 * n = 4 * 9

n = 36/8

But we know that n is a reciprocal of a number, so we need to flip the numerator and denomiator in n

Answer: 8/36 = 2/9

Answer:

x = 2.55 miles per day

Step-by-step explanation:

In English:     5 days * 'x' miles per day = 12 & 3/4 miles total

In algebra:    5x = 12.75

                       x = 12.75 ÷ 5

                      x = 2.55 miles per day
