Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use Pythagorean Theorem.

a = 19

b = x

c = 21

Step 2: Find x

And we have our final answer!

Answer:

Hypotenuse is the longest side. And the side opposite to small angle are small sizes

Step-by-step explanation:

450 is longest

40.0 is the shortest

Answer: False

Step-by-step explanation:

To see if (-2,0) is a solution to the given equation, we can plug in the point and solve. If we get the same answer, then it is a solution.

2(-2)-3(0)=6            [multiply]

-4-0=6                     [subtract]

-4≠6

Now, the doesn't equal sign tells us that -4 is not equal to 6. This means the given point is not a solution to the equation, making it false.

Answer:

63/100 (the simplest form)

Step-by-step explanation:

1. Covert decimal into fraction:

0.63 = 63/100

2. Simplify (1 is the greatest common divisor of 63 and 100. The result can't be further reduced):

63/100

I'm very sorry but i don't know the answer to this queshtion

Answer:

t = 91

Step-by-step explanation:

t - 15 = 76

t - 15 + 15 = 76 + 15

t = 91

Answer:

  62, 64, 66

Step-by-step explanation:

I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...

  (x -2) +(x +2) = 128

  2x = 128 . . . . . collect terms

  x = 64 . . . . . . . divide by 2

The middle integer is 64, so the three even integers are 62, 64, 66.

Answer:

Her error was multiplying numerator by numerator ( that is Quantity of Bone-shaped treats)

Step-by-step explanation:

Sarah's calculation

Let

x = cost of 12 Bone-shaped treats

Quantity of Bone-shaped treats : price

5 : 3.5 = 12 : x

(5/3.5) = (12/x)

Cross product

3.5x=60 (Here is her error)

x=17.14

Correct calculation

Quantity of Bone-shaped treats : price

5 : 3.5 = 12 : x

5 / 3.5 = 12 / x

Cross product

5 * x = 3.5 * 12

5x = 42

x = 42 / 5

= 8.4

x = $8.4

Her error was multiplying numerator by numerator ( that is Quantity of Bone-shaped treats)

Instead of multiplying Quantity of Bone-shaped treats by cost

Answer:

Sarah multiplied the denominator by the denominator and the numerator by the numerator instead of finding the cross products. The equation should be 5x = 42, so the cost should be $8.40.

Step-by-step explanation:

11/3  (eleven divided by three)

In decimal form, this is approximately 12.667 km per hour.

As an improper fraction, 12 & 2/3 = 38/3

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

Explanation:

Let's use this formula

a & b/c = (a*c+b)/c

to convert the given mixed number to an improper fraction.

3 & 1/6 = (3*6+1)/6

3 & 1/6 = 19/6

The mixed number 3 & 1/6 is the same as the improper fraction 19/6

The hamster runs 19/6 km in 1/4 of an hour.

We can express that as the ratio

19/6 km : 1/4 hr

Multiply both parts by 4 so that the "1/4 hr" turns into "1 hr"

19/6 km : 1/4 hr

4*19/6 km : 4*1/4 hr

76/6 km : 1 hr

38/3 km : 1 hr

Harvey runs 38/3 km in 1 hour

Let's convert that to a mixed number

38/3 leads to a decimal, but 36/3 leads to a whole number

So,

38/3 = (36+2)/3

38/3 = 36/3 + 2/3

38/3 = 12 + 2/3

38/3 = 12 & 2/3

You can use your calculator to note that 38/3 = 12.667 approximately, which is also the value of 12 & 2/3, since 2/3 = 0.667 approximately. This helps confirm we did the conversion correctly.

Answer:

Area = 76[tex]m^{2}[/tex]

Step-by-step explanation:

you can cut into two rectangles

first one:

top and bottom sides = 4m

two sides = 9m

Area = b*h = 9m * 4m = 36 [tex]m^{2}[/tex]

second one

top and bottom sides = 8m

two sides = 14m - 9m = 5m

Area = b*h = 8m * 5m = 40[tex]m^{2}[/tex]

Now add both rectangle areas for the total shaded Area = 36 + 40 = 76[tex]m^{2}[/tex]
