A triangle has sides with lengths of 5 yards, 12 yards, and 13 yards. Is it a right triangle?

Answer:

916.57 pounds

Step-by-step explanation:

Cost of beef = 7.53 pounds × 9

= 67.77 pounds

Cost of potatoes = 6.45 pounds × 9

= 58.05 pounds

Cost of carrots = 6.23 pounds × 4

= 24.92 pounds

Total cost = 67.77 pounds + 58.05 pounds + 24.92 pounds

= 150.74 pounds

Total revenue = 27 meals × 39.53 pounds

= 1067.31 pounds

Total profits = Total revenue - Total cost

= 1067.31 pounds - 150.74 pounds

= 916.57 pounds

Answer:

it b

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

all 3 angles of a triangle must equal 180 degrees, so if it tell you that there is a 68 degree angle, and a 90 degree angle(because if the right angle), then the last angle must be 22, because 180-(68+90)=22

Answer:

x = 5

Step-by-step explanation:

To get the value of x we will use similar triangles as shown;

AT/AG = AB/AC

9/3 = x+10/3x-10

Cross multiply

3(x+10) = 9(3x-10)

3x + 30 = 27x - 90

Collect like terms

3x - 27x = -90 - 30

-24x = -120

x = 120/24

x = 5

Hence the value of x is 5

Answer:

2

Step-by-step explanation:

To find the slope given two points you do [tex]\frac{y2-y1}{x2-x1}[/tex]

so we just plug in the y values and x values

[tex]\frac{-7-5}{-2-4}[/tex]

[tex]-7-5=-12[/tex]

[tex]-2-4=-6[/tex]

[tex]\frac{-12}{-6} =2[/tex]

Therefore the slope is 2

Actually Welcome to the Concept of the Angle sum property of a Triangle.

hence,

==> 4x + 8° + 60° + 60° = 180

==> 4x + 128° = 180°

==> 4x = 180 - 128

==> 4x = 52°

==> x = 52/4

==> x = 13°

hence the value of x = 13 °

Answer:

15.73

Step-by-step explanation: I just kinda guessed and got it right.

You need to pay $15.73  per hour to employees in next two years.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Wages have been rising at 6% per year in your area.

Next year, you need to pay employees,

= 14 + 14 x 6/100

= $14.84

Again next year,

you need to pay = 14.84 + 14.84 x 6/100

= $15.73

Therefore, the wage is $15.73 per hour to employees.

Answer:

70 is 125% of 50

Step-by-step explanation:

I hope this helped :)

The percentage value of 70 to  56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

Given that, to find what percent of 70 in 56.

To find out if the percentage of 70 is 56, follow the steps:

Step 1:Find the ratio of the two numbers that is the ratio of  70 and 56 gives:

[tex]70:56 = 70/56[/tex]

Divide both numerator and denominator by 14 yields in:

[tex]= 5/4[/tex]

Step 2: Convert the result of step 1 into decimals by a long division of  5 by 4.

[tex]5/4 = 1.25[/tex]

Step 3: Find the percentage value of the decimal by multiplying the decimal by 100.

[tex]1.25 \times100 = 125[/tex]%

Therefore, the percentage value of 70 to  56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

Explanation:

Part (a)

The horizontal portion is shown to be 87.3 cm long. This is the result after rounding has occurred. Specifically, rounding to one decimal place (tenths). The question is: What could the number have been before rounding?

You have to think in reverse of the usual rounding process.

The values 87.25, 87.26, 8.27, ... 8.33, 87.34 all round to 87.3 when we round to one decimal digit. Note the hundredths digit is increasing by 1 each time. We can see that 87.34 is the largest possible value for the horizontal piece. After that, 87.35 will round to 87.4 which is just out of reach.  

Through similar logic/reasoning, the vertical side can be at most 51.84 cm.

The area of the rectangle could be 87.34*51.84 = 4527.7056 which is the upper bound for the area. This is the largest possible area, given the values in the diagram, since we made each value as large as possible.

In short, 4527.7056 square cm is the max area.

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

Part (b)

We use the idea of part (a), but we'll use the smallest possible values this time.

So we go with 87.25 for the horizontal portion and 51.75 for the vertical portion.

Compute the perimeter with these smallest dimensions.

P = 2*(length + width)

P = 2*(87.25 + 51.75)

P = 278

The smallest perimeter possible is 278 cm which is the lower bound of the perimeter. This is guaranteed to be the smallest perimeter possible because we made the sides as small as possible, while staying in the restrictions as discussed in the previous section.

Answer:

Step-by-step explanation:

Are the volumes equal?      No, so throw out the first and the last one.

Is the volume of the pyramid greater than the volume of prism?  

                                            No, so throw out the third one

so by inspection it must be the remaining one

or mathematically

    vol pyramid = (1/3)(base)(height)

    vol prism     =  (base)(height)

              vol pyramid   /   vol prism      

           (1/3)(base)(height) / (base)(height)   = 1/3
