Vance wants to determine if an old photo frame is still rectangular. The height of the frame is

sveticcg [70]

Answer:

The old photo frame is still rectangular

Step-by-step explanation:

Rectangles

The rectangle shape can be identified because it has 4 internal angles of 90° each. The diagonal forms with two adjacent sides a right triangle where the Pythagora's Theorem must stand. Being a and b the length of the sides of the rectangle and d the diagonal, then:

$d^2=a^2+b^2$

Vince's photo frame has dimensions of 8 inches and 6 inches, with a diagonal of 10 inches. If the above condition is met, then the frame is still rectangular.

Calculating:

$10^2=6^2+8^2$

$100=36+64$

$100=100$

Since the condition is met, the old photo frame is still rectangular

schepotkina [342]

Answer:

two unequal real roots

What is the range of values for the measurement 500±4%

Anestetic [448]

To be able to determine the unknown range of the number with tolerance given, first we need to determine the 4% of 500. This can be done by multiplying 500 by the decimal equivalent of 4% which is equal to 0.04.

tolerance = (500) x (0.04) = 20

Lower limit: The lower limit is determined by subtracting 20 from 500.
Lower limit = 500 - 20 = 480

Upper limit: The upper limit is determined by adding 20 to the base value 500.
Upper limit = 500 + 20 = 520

The values, therefore, rang from 480 to 500.

ANSWER: 480 - 520
