C.14 cm
D.10 cm
Answers
The space diagonal of a rectangular prism is derived using the following formula:
d = √(l² + w² + h²)
l = 6; w = 5; h = 9
d = √6² + 5² + 9²
d = √36 + 25 + 81
d = √142
d = 11.916 ⇒ 12 cm
slant height of the given pyramid :
l = slant height
h = height
a = base radius
l = √h² + a²
i'm assuming that the pyramid base is also the base radius
l = √8² + 12²
l = √64 + 144
l = √208
I = 14.42 ⇒ 14cm
in the event that the pyramid base is not the radius, then 12/2; 6cm
l = √8² + 6²
l = √64 + 36
l = √100
l = 10 cm

b. Convert the rounded measurement to meters. Write an equation to show your work.
Answers
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

Answer:
A.2.251 cm , 2.349 cm, 2.295 cm
B. 0.023 meters.
Step-by-step explanation:
2 yards
31 feet
51 feet
Answers
Alright, lets get started.
Sophie has 5 pieces of string that are 4 yards each.
1 yards = 3 feet,
So, 4 yards = feet
Total number of string she has = 5 piece
So, total length she has = feet
It means she had 60 feet string in starting.
Now, She uses 3 pieces that are each 3 feet long, means
She uses = feet
So, remaining string length will be = feet
Means 51 feet string does Sophie have. : Answer
Hope it will help :)
