Answer:
B = 12.8 cm (to 1.d.p)
D = 24.1 cm (to 1.d.p)
Step-by-step explanation:
Using Pythagoras Theorem:
B: 4^2 + 3.5^2 = 28.25
square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.
To find perimeter add sides a, b and c so...
perimeter of triangle B = 12.8 cm (to 1 decimal place)
D: 10^2 - 6.5^2 = 57.75
square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.
To find perimeter add sides a, b and c so...
perimeter of triangle D = 24.1 cm (to 1 decimal place)
^2 indicates squared
Sorry but I'm not too sure / confident about A or C
Answer: An experimental probability is based on past events, and a theoretical probability is based on analyzing what could happen. An experimental probability approaches a theoretical one when enough random samples are used.
Answer:
1,776
Step-by-step explanation:
1. There are <u>37</u> children in the classroom
2. Each student will get <u>48</u> pencils
3. The teacher wants to give 48 pencils evenly to 37 children
4. 48 x 37 = <u>1,776</u>
A: The teacher will have to give out <u>1,776</u> pencils.
Answer:
There is a solution. Here's how:
Step-by-step explanation:
So, you work out the problem, and you lay it out here:
5-4+7+1=5-4+7x+1.
First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:
-4+7+1=-4+7x+1
Next, you add 4 to both sides, which makes you identify the identity.
Here's your equation now:
7+1=7x+1
Now, you subtract 1 from both sides.
Here's your equation now:
7=7x
Finally, divide both sides by 7, while identifying the identity.
x=1.
