Here Is a trapozhum and a squnro, The lengths of the parnllel sides of the
trapezhum are 10 cm and 14 cm, The helght of tho trhpoziurm is 12 cm. The nren of
the squpre is equal to the aren of the trapeziurn. Work out the perimeter of the
square
Answer:
48 cm
Step-by-step explanation:
Here Is a trapezium and a square, The lengths of the parallel sides of the trapezium are 10 cm and 14 cm, The height of the trapezium is 12 cm. The area of the square is equal to the area of the trapezium. Work out the perimeter of the square.
Solution:
The area of the trapezium is given by:
A = (1/2)(a + b)h
where h is the height of the trapezium = 12 cm, a and b are the parallel sides. Given that a = 10 cm, b = 14 cm, hence:
A = (1/2)(10 + 14)12 = 144 cm²
Area of trapezium = Area of square
Area of square = 144 cm²
Area of square = length * length = length²
length² = 144 cm²
length = √144 = 12 cm
Perimeter = 4 * length = 4 * 12 cm = 48 cm

Mom used 1/2 package of pepperoni putting an equal amount on each of the three pizza she made what fration of the package of pepperoni did she use on each pizza
Answer: 1/6 package of pepperoni
Step-by-step explanation:
There were three pizzas and Mom used 1/2 package of pepperoni on all of them in an equal amount.
The fraction that each pizza got is therefore this 1/2 divided by the number of pizzas it was used on which is three.
= 1/2 ÷ 3
This is the same as:
= 1/2 * 1/3
= 1/6 package of pepperoni

sandra used 2 jars of beads to make 16 necklaces how many jars of beads would she need to make 192 neclaces
Answer:
24 Jars
Step-by-step explanation:
Do 16/2, which gives you eight for every necklace. Then do 192/8 which would give you 24. So, she would need 24 jars for 192 necklaces.
Answer:
16÷2=8
8÷192=24
its 24
all you have to do is divide the 16 and 2 to see how many is in each jar and how much they have done then just just divide that number with 192.

Step-by-step explanation:
A fish swims upstream a distance of 16 miles in a river with a current of 3 miles per hour. The fish returns swimming
downstream the same distance. The roundtrip up and down the river takes the fish 4 hours. Assuming that the fish
swims at a constant speed in still water, what is the fish's speed in still water?
Answer:
9 mph = the speed in still water
Step-by-step explanation:
Let r = the speed in still water
Then the speed going down stream is r + 3
and the speed going upstream is r - 3
d = rt or t = d/r
time going downstream is 16/(r + 3) and time going upstream is 16/(r - 3)
The total time was 4 hours, so
[tex]\frac{16}{r + 3} + \frac{16}{r - 3} = 4[/tex] Multiply thru the equation by (r + 3)(r - 3)
Then 16(r - 3) + 16(r + 3) = 4(r + 3)(r - 3)
16r - 48 + 16r + 48 = [tex]4r^{2}[/tex] - 36
[tex]4r^{2}[/tex] - 36 = 32r
[tex]4r^{2}[/tex] - 32r - 36 = 0
[tex]4(r^{2} - 8r - 9) = 0[/tex]
4(r - 9)(r + 1) = 0
r = 9 or -1
But a rate of speed cannot be negative, so x ≠ -1
So, r = 9 mph = the speed in still water

What is intersection?The intersection of two sets is the set of all those elements which are common to both of the sets.
here, we have,
Solution:
Let students who likes tennis be represented by set T.
Let students who likes football be represented by set F.
Let students who likes baseball be represented by set B.
Given that
Number of students who likes tennis that is n(T) = 18
Number of students who likes football that is n(F) = 25
Number of students who likes tennis and football = n( T ∩ F ) = 10
Number of students who likes tennis and baseball = n( T ∩ B ) = 13
Number of students who likes football and baseball = n( F ∩ B ) = 20
Number of students who likes all three sports = n(T ∩ F ∩ B ) = 8
Number of students who likes none of the sports = 9.
Determining number of students who like only tennis and football:
number of students who like only tennis and football = Number of students who likes tennis and football - Number of students who likes all three sports
so number of students who like only tennis and football
= n( T ∩ F ) - n(T ∩ F ∩ B )
= 10 – 8
= 2
Determining number of students who like only tennis and baseball:
number of students who like only tennis and baseball = Number of students who likes tennis and baseball - Number of students who likes all three sports
so number of students who like only tennis and baseball
= n( T ∩ B ) - n(T ∩ F ∩ B )
= 13 – 8
= 5
Determining number of students who like only baseball and football:
number of students who like only baseball and football = Number of students who likes baseball and football - Number of students who likes all three sports
so number of students who like only baseball and football
= n( B∩ F ) - n(T ∩ F ∩ B)
= 20 – 8
= 12
Summarizing the result :
number of students who like only tennis and football = 2
number of students who like only tennis and baseball = 5
number of students who like only baseball and football = 12.
