Anna and Paddy take part in the same fun run.
Anna completed the fun run in 2 hours.
Her average speed was 6 kilometres per hour.
Paddy completed the fun run in 90 minutes.
(a) Work out Paddy's average speed in kilometres per hour.
Answer:
I wanna say 4.6 kmph
Step-by-step explanation:
6(average) /2(hr)=3kmph
1.20(hr) / 6 (kmph) = 4.6
If Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours. Her average speed was 6 kilometres per hour. Paddy completed the fun run in 90 minutes. Then 4.5 km/h is Paddy's average speed
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours.
Her average speed was 6 kilometres per hour.
Paddy completed the fun run in 90 minutes.
We need to find paddys average speed in kilometres per hour.
Let us convert 2 hrs to minutes=120 minutes
6/120=x/90
Apply cross multiplication
90×6=120x
540=120x
Divide both sides by 120
x=4.5
Hence 4.5 kilometer per hour is the Paddy's average speed.

A home value increases at a rate of 2.3% per year. If you purchased a home for 192,300, what would be the value of the home in 10 years? Round to the nearest cent.
9514 1404 393
Answer:
$241,399.09
Step-by-step explanation:
The value is increasing exponentially with a growth factor of 1.023, so it will be ...
v(t) = 192,300×1.023^t
v(10) = 192,300×1.023^10 ≈ 241,399.09
The value is predicted to be $241,399.09 in 10 years.
3/4(1/4x + 8) - (1/2x + 2) = 3/8(4-x) - 1/4x
What is the value of x?
Step-by-step explanation:
0.75(0.25x+8)-(0.5x+2)=0.375(4-x)-0.25x
0.1875x+6-0.5x-2=1.5-0.375x-0.25x
0.1875x-0.5x+0.375x+0.25x=1.5-6+2
0.3125x=-2.5
x=-2.5/0.3125
x= -8

Find the length of TU as indicates in the picture, will name Brainliest.
Answer:
7
Step-by-step explanation:
2x-5 + 2x-7 = 12
this is because the length of the line is given to be 12
so the sum of the two equations should be 12
2x+2x -5-7 = 12
4x - 12 = 12
4x = 12+12
4x = 24
x = 6
there TU = 2x-5 =2(6) -5 =12-5=7
TU = 7
Ella is making a kite in the shape of a triangular prism, but with both ends open. Which net shows the faces that
would be used to calculate surface area shaded?
Answer: the answer is the second one :)
Step-by-step explanation:
The net is shown in the picture that can used to calculate surface area shaded.
What is quadrilateral?It is defined as the four-sided polygon in geometry having four edges and four corners.
We know that kite is quadrilateral, having:
Two pairs of congruent sides.It has one pair of opposite congruent angles.The diagonals of a kite are perpendicular.One diagonal is bisected.The top and bottom angles are bisected butKite does not have congruent diagonals.
As we have given that, Ella is making a kite in the shape of a triangular prism, but with both ends open.
Thus, the net is shown in the picture that can used to calculate surface area shaded.

Answer:
x= 20,1 degrees
Step-by-step explanation:
The sum of the inner angles of a triangle is 180 degrees
So it must be
3x-11+6x-10+x = 180
added up the terms with x
10x -11-10 = 180
added up the terms without x
10x - 21 = 180
added up (21) in the two members of the equation
10x-21+21 = 180+21
10x = 201
divide the two members by 10
x = 20,1 degrees
1/5+3/25x-3=2 3/5 it said for me to solve?
Answer: x = 45
simplify both sides of the equation.
3/25x + -14/5 = 13/5
add 14/5 to both sides.
3/25x = 27/5
multiply both sides by 25/3.
x = 45
