Pythagoras theorem

diagonal² = length² + width²

$13²$ = $12²$ + width²

$169$ = $144$ + width²

$25$ = width²

width = $5$ m

so, Oakdale Avenue is $5$ m wide.

Step-by-step explanation:

I assume they intersect at a right angle (90°).

then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.

the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.

so, by using Pythagoras we have

diagonal² = length² + width²

13² = 12² + width²

169 = 144 + width²

25 = width²

width = 5 m

so, Oakdale Avenue is 5 m wide.

Which of these expressions demonstrates the identity property? 25(0) = 25 25(1) = 25 25 + 0 = 25 25 + 1 = 25

tresset_1 [31]

The expressions which demonstrates the identity property of multiplication is; 25(1) = 25 option B

<h3>Identity Property</h3>

Identity Property of Multiplication states that any number multiplied by 1 does not change, that is, it is constant or remains the same

Check all options

25(0) = 25

0 = 25

Not true

25(1) = 25

25 = 25

True (identity property of multiplication holds)

25 + 0 = 25

25 = 25

True (Not identity property of multiplication)

25 + 1 = 25

26 = 25

Not true

Joy knits a square blanket that has an area of 1,500 square inches . What is the approximant length for each side of the blanket

Alex777 [14]

Answer:

1) Option C - 39 inches

2) Option C - 12167 cubic feet

Step-by-step explanation:

1) Given : Joy knits a square blanket that has an area of 1,500 square inches

To find : What is the approximate length for each side of the blanket.

Solution: Area of square = 1500 square inches

Let the side of the blanket = s

Formula of area of square is $A= s^2$

$1500= s^2$

$s= \sqrt{1500}$

$s=38.7$

Approximately Side of blanket = 39 inches

Therefore, Option C is correct.

2) Given : Jeff is an architect and is drawing the plan for a room addition for a client. If the shape of the room is a cube.

To find : what is the volume in cubic feet if the length is 23 feet?

Solution: Length of side of a cube (a)= 23 feet

Let the volume of a cube = V

Formula of Volume of cube is $V= a^3$

$V= (23)^3$

$V= 12167$

Volume of a cube = 12167 cubic feet

Therefore, Option C is correct.
