Does 12,5,13 make a right triangle?

Answer:

the price of each snack be R $9.00

Step-by-step explanation:

Let us assume the snack be x

And, the ice cream be y

Now according to the question

2x + y = $21

And,

3x  + 2y = $33

Now multiply by 2 in equation 1

So,

4x + 2y = $42

3x + 2y = $33

x = 9

Hence, the price of each snack be R $9.00

Center = (-1,0)   Radius= 1

when you complete the square your equation should look something like

(x²+2x+1) (y²+0) = 1.The 1 on the left side coming from (b/2)² which is (2/2)² which equals 1 and whatever you add to one side, you have to add to the other so when you add 0+1 you get the 1 on the right side. Then factor or use the (b/2) from earlier without the ² so you should get (x²+1) + (y²+0) = 1. Flip the sign so you have negative 1 and 0. For the radius, square the right side and of course, [tex]\sqrt{1}[/tex] is simply 1 so your radius is 1. A lot of 1's huh? lol at least it makes the operations nice and simple :)

Step-by-step explanation:

Find area od the rectangle:

14 x 26 = 364

Find area of the triangle:

10 x 26 = 260

260/2 = 130

Add the areas together:

364 + 130 = 494

Answer:

5(5x+11)

Step-by-step explanation:

Answer: 5(5x+11)

Step-by-step explanation:

What multiplies to be 25x, 5 and 5 x is the answer, 5 goes on the left because of the next step which is what times what equals 55. 5 times 11 equals 55. So 11 is on the top while 5 is on the left,

Answer:

-23

Step-by-step explanation:

Using the absolute rule,

[tex]\left|-a\right|=a[/tex].

Therefore,

[tex]-|-23|=-23[/tex]

(It becomes 23 first, but then you stick the negative sign after)

Answer:

Josie is correct.

Step-by-step explanation:

There are other ways of finding the value of the function at x = 1.

For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.  

Answer:

x = 16/y

or

y =16/x

Step-by-step explanation:

31=xy+15

subtract 15 from both sides of the equation:

xy = 16

x = 16/y

or

y =16/x

Answer: I feel the answer is C

Step-by-step explanation:

The three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

A box and whisker plot displays the minimum value, lower quartile (Q1), median, upper quartile (Q3), and maximum values of a data set.

Let's analyze each of the given statements given the box and whisker plots for both groups:

Statement A is TRUE:

Median time for Group B = 40.

Statement B is FALSE:

Median value for Group A is between 45 and 50

Median value for Group A is 40.

Therefore, Group B does NOT have median value greater than Group A.

Statement C is TRUE:

The interquartile range (IQR) for Group A and Group are similar, therefore, data for Group B varies slightly more than Group A.

Statement D is TRUE while E is FALSE:

Spread for Group A (IQR) = 55 - 30 = 25 minutes

Therefore, the three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

Answer:

72 meters

Step-by-step explanation:

12 times 9 is 72

Answer:

243 m²

Step-by-step explanation:

Given the scale is 4 : 6 = 2 : 3 , then

scale of areas = 2² : 3² = 4 : 9

area of scale drawing = 12 × 9 = 108 cm²

let x be the actual area then using proportion

[tex]\frac{4}{108}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

4x = 972 ( divide both sides by 4 )

x = 243

Actual area = 243 m²

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Answer:

y = 3x + 62

Step-by-step explanation:

Trend line equation in the form :

y = mx + b

m = slope

b = intercept

Using the points :

(0, 62) ; (6, 80)

Slope, m = Rise / Run = (y2-y1) / (x2 - x1)

y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0

m = (80 - 62) / (6 - 0)

m = 18 / 6

m = 3

Intercept, b = value of y when x = 0

(0, 62) ; hence, b = 62

y = 3x + b

y = 3x + 62

Answer:

option d. perimeter of quadrilateral=35

Let's say the price of an item is $1

Scenario #1 - 40% off $1  = 40 cents OFF

The discounted price = 60 cents

Now the 10% off of 60 cents

60-6 = 54 cents.

Scenario #2 - 10% of $1

The discounted price = 10 cents

100(cents) - 10 = 90 cents

Now the 40% off of 90 cents

90-36 = 54 cents

Let's try another value to confirm

Let's say the price of an item is $2

Scenario #1  - 40% off $2 = 80 cents OFF

200-80= 120 = $1.20

Now the 10% off of $1.20

120-12= 108 = $1.08

Scenario #2 - 10% off $2 = 20 cents OFF

200-20 = 180= 1.80

Now the 40% off of $1.80

180-72 = 108 = 1.08

With these two examples we can confirm either order
