The formula for area of a triangle is 1/2 x base x height.
Using the given information we can solve for the height:
494 = 1/2 x 38 x height
Divide both sides by 38:
13 = 1/2 x height
Multiply each side by 2:
26 = height.
The height is 26 cm.
Answer:
Simplification of the expression (3.1)⋅(10.75−3.55) is:
22.32
Step-by-step explanation:
We have to simplify:
(3.1)⋅(10.75−3.55)
(3.1)⋅(10.75−3.55)=(3.1)·(7.2)
=22.32
Hence, on simplifying the expression (3.1)⋅(10.75−3.55) , we get:
22.32
2.251 cm
2.349 cm
2.352 cm
2.295 cm
b. Convert the rounded measurement to meters. Write an equation to show your work.
a. The possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.
b. Rounded measurement in meters is 0.023 meters
a. To determine which measurements could be the actual measurement of the rainfall, we need to consider how rounding works.
When rounding to the nearest tenth of a centimeter, any measurement with a hundredth digit of 5 or greater rounds up, and any measurement with a hundredth digit less than 5 rounds down.
Given that the rounded measurement is 2.3 cm, let's evaluate the measurements:
2.251 cm: Rounds down to 2.3 cm
2.349 cm: Rounds up to 2.3 cm
2.352 cm: Rounds up to 2.4 cm
2.295 cm: Rounds down to 2.3 cm
So, the possible actual measurements are 2.251 cm, 2.349 cm and 2.295 cm.
b. To convert the rounded measurement to meters, we need to divide it by 100, since there are 100 centimeters in a meter.
Rounded measurement: 2.3 cm
Conversion to meters: 2.3 cm / 100 = 0.023 meters
Equation: Rounded Measurement (in meters) = Rounded Measurement (in centimeters) / 100
Rounded Measurement (in meters) = 2.3 cm / 100
= 0.023 meters
