Answer:

$26.20

Step-by-step explanation:

first you multiple 2.12 by 10 then you add 6 to get your answer. (2.12×10)+6 (21.2)+6=26.2

To get the area of the shaded region, we must subtract the area of the bigger triangle on the outside and the area of the smaller triangle inside the bigger triangle.

Set up the equation:

  Area of big triangle - Area of small triangle = [tex]\frac{1}{2} *19*19 - \frac{1}{2} *13*13[/tex][tex]= \frac{1}{2} (19^{2} -13^{2} ) = \frac{1}{2}*192 = 96[/tex]

So the area of the shaded region is 96.

You get a negative number

-3 + (-10) = -13

Answer:

A negative number.

Step-by-step explanation:

For example, -5+-3 is -8. This is because as you add negative numbers, you go further down the number line, therefore it becomes smaller and a small negative number has a bigger number in front of the minus sign.

Answer:

x=12

Step-by-step explanation:

Since it is on a right angle we can equate the sum of these 2 angles to 90:

3x+x+42=90

Simplify:

4x+42=90

Subtract 42 from both sides:

4x+42-42=90-42

Simplify:

4x=48

Divide both sides by 4

4x÷4=48÷4

Simplify

x=12

Answer:

Step-by-step explanation:

The overall angle in total is 90 degrees. The angles 'x+42' and '3x' equal ninety degrees, so we get the equation:

x + 42 + 3x = 90

4x + 42 = 90

4x = 48

x = 12

Hope I could help!~ have a good day/night :]

Answer: So for helium the equation above gives v= 973 m/s at STP, and 1,020 m/s at 298 K. Since the speed, frequency and length of a sound wave are related by the equation ν = v/λ, the frequency of a sound produced by a resonator of a particular length is proportional to the speed of sound in the particular gas that fills the resonator.  For air at STP (0 °C and 1 atm), γ = 1.40, and v= √((1.40 × 8.314 J/mol·K ×273.16 K)/(2.8967 × 10-2kg/mol)) = 331 m/s.

Answer:

34 m

Step-by-step explanation:

So you know one side of the garden is 9 meters long and you know that the area is 72 square meters. To find out the length of the other side you would divide 72 by 9 which gives you 8. tithe you add 8 and 9 together twice or 16 and 18. The end result is 34 m.

Answer:

Graphic Representation of the Equations is in the image above

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = 4x - 5

// Plug this in for variable y in equation [1]

[1] (4x-5) - 2x = -1

[1] 2x = 4

// Solve equation [1] for the variable x

[1] 2x = 4

[1] x = 2

// By now we know this much :

y = 4x-5

x = 2

// Use the x value to solve for y

y = 4(2)-5 = 3

Solution :

{y,x} = {3,2}

y=2x-1

y=4x-5

Now graph both equations

Answer: $6.50

Step-by-step explanation:

First you do 4.55/7 and you get 0.65, then you multiply that by 10 which will get you $6.50.

it's 6.50 because when you divide 4.55/7 it's 0.65 multiplied by 10 it's 6.50

Answer:

7.9 miles

Step-by-step explanation:

pi = 3.14

r = radius = 10 miles

c = circumference

substituting the values

c = 2pi*r

c = 2 * 3.14 * 10

c = 62.83 miles

The ship has traveled 45°  due north

so,

d = ( total circular distance * 45 ) / 360

substituting the values:

we get;

d = ( 62.83 * 45 ) / 360

  = 7.85 miles

  = 7.9 miles

The expression shows the area of the shaded region in terms of A and B are 4A + B, 1.5B, and 12A.

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle.

Given

The area of one of the small right triangles outlined in blue is A cm2, while the area of the square outlined in red is B.

There are 4 triangles with an area of 4 so that is 4A and since there is only one square the area of the whole thing is 4A+B.

Each triangle is also equal to 1/8 of the square.

This means A=B/8 or B=8A.

First replacing B in the previous equation you get 4A+8A which is 12A.

Then replacing A with B/8 you get 4(B/8)+B which is B/2+B which is 3B/2 and 3/2 is 1.5 so 3/2B is equal to 1.5B.

Hence, the expression shows the area of the shaded region in terms of A and B are 4A + B, 1.5B, and 12A.

ok well i need a image and or the full question x could = anything unless i can get the question the full question  

Step-by-step explanation:

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

Explanation:

The line of best fit here is y = 6x+62

We started at (0,62) and go up 6 units and to the right 1 unit each time we move along this line.

If we tried something like x = 1, then,

y = 6x+62

y = 6*1+62

y = 6+62

y = 68

Meaning that someone spending 1 hour per week doing homework would lead to an estimated score of 68. This matches what the graph shows, and it helps confirm we have the correct regression line equation.

Let's now plug in x = 5

y = 6x+62

y = 6*5+62

y = 30+62

y = 92

Someone doing 5 hours of homework per week is estimated to get a score of about 92.

Answer:The correct statement comparing modes to ranges is ''The modes differ by 40 and the range differs by 40'' is true.

Step-by-step explanation:The table below shows the number of pages in each book he read last summer and the number of pages in each book he read this summer.

Number of Pages   Elias Read during the Summer,

Last summer: 140 220 190 180 190

This summer: 150 170 150 190 180

We have to determine,

Which statement comparing the modes to the ranges is true.

According to the question,

The mode of a data set is the value that occurs most often.

The data from last summer,

The value 190 is in the list twice, while all other values are only in once.  This means 190 is the mode.

The data from this summer,

The value 150 is in the list twice, while all other values are only in once.  This means 150 is the mode.

The difference in modes is 190 - 150 = 40.

The range is the difference between the maximum and minimum values in a data set.

The maximum value is 220 and the minimum value is 140,

Then,

Range = 220 - 140 = 80

The range for this summer's data,

The maximum is 190 and the minimum is 150;

Then,

Range = 190 - 150 = 40 for the range.

Therefore,

The difference in ranges is 80 - 40 = 40.

Hence, The modes differ by 40 and the range differs by 40
