Answer:

B) 7.1 ft

Step-by-step explanation:

Two ways to go about this:

Method 1:

Recognize that since the side lengths are equal to each other, then the hypotenuse must be equal to 5√2 or about 7.1 feet since the triangle is a 45-45-90 triangle.

Method 2:

By using the Pythagorean Theorem, a^2+b^2=c^2, we have 5^2+5^2=c^2 --> 25+25=c^2 --> 50=c^2 --> 7.1≈c

Answer:

-1

Step-by-step explanation:

1/3 - 2/5 = x/15

Make denominators equal.

5/15 - 6/15 = x/15

Cancel the denominators.

5 - 6 = x

-1 = x

The sum of my digits is an even number. My first digit is 6 less than my second digit. 12 is the number you get when you add my

Arte-miy333 [17]

Answer:

Step-by-step explanation:

Let a and b represent the first and second digits, respectively.

... a = b -6 . . . . . . the first digit is 6 less than the second

... a + b = 12 . . . . .the sum of digits is 12 (an even number)

Using the expression in the first equation, we can substitute for a in the second equation:

... (b -6) +b = 12

... 2b = 18 . . . . . . add 6, simplify

... b = 9 . . . . . . . . .divide by 2

... a = 9 -6 = 3 . . . . from the first equation

The number is 39.

What is the area of rhombus ABCD ? Enter your answer in the box. Do not round at any steps.

Norma-Jean [14]

Answer:

The area of rhombus = 24

Step-by-step explanation:

The area of rhombus = base times height

For the given rhombus :

Height = The length of DP

Base = the length of any side of the rhombus as AB

The length ot two point (x₁ , y₁) and (x₂ , y₂) = $\sqrt{(x_{1} -x_{2} )^2+(y_{1} -y_{2})^2}$

From the given figure:

D = (-5,-2) , P = (-3.8 , 1.6) , A = (1,0) , B = (7 , -2)

DP = $\sqrt{(-5-(-3.8))^2+(-2-1.6)^2}$ = √14.4

AB = $\sqrt{(1-7)^2+(0-(-2))^2}$ = √40

So,

The area of rhombus = √14.4 * √40 = √576 = 24
