2. Sarah incorrectly multiplied 9 and 6. Her estimate should be $63.
3. Sarah rounded 9.5 up to 10. Her estimate of $54 is too high.
4. Sarah rounded $6.95 and 9.5 down. Her estimate of $54 is too low.

Jada and her friends want to go indoor skating on Saturday night. Jacaranda Skating Zone charges $40 for entry and $12 per hour to skate, while Wiles Skating Zone charges $10 for entry and $22 per hour to skate. At how many hours would it be the same cost at either skating zones?
Answers
At 3 hours both Jacaranda and Wiles would have the same cost
Let y represent the total charges by Jacaranda and x represent the number of hours. Hence:
y = 12x + 40
Let z represent the total charges by wiles and x represent the number of hours. Hence:
z = 22x + 10
Since they are to have the same cost, hence:
y = z
12x + 40 = 22x + 10
10x = 30
x = 3 hours
Therefore at 3 hours both Jacaranda and Wiles would have the same cost.

slope=0, goes through the point (0,6)
Answers
Answer:
y=6
Step-by-step explanation:
no slope means no X or M in y=mx+b
leaves you with y=b which is whatever y is in the cordinate (x,y)
in this case, 6
Answer:
y=6
Step-by-step explanation:
We can use point slope form
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
y-6 = 0(x-0)
y-6 = 0
Add 6 to each side
y-6+6 = 0+6
y=6
One of the legs of a right triangle is twice as long as the other, and perimeter of the triangle is 28. Find the lengths of all three sides, to three decimal places
Answers
Step-by-step explanation:
One leg is x, the second leg is 2x and the hypotenuse is:
h = [tex]\sqrt{x^2+(2x)^2} =\sqrt{5x^2} =x\sqrt{5}[/tex]Perimeter is:
x + 2x + x√5 = 28x(3 + √5) = 28x = 28/(3 + √5) ≈ 5.348The sides are:

Answers
Answer:
{t: 0.6 < t < 99.4}.
Step-by-step explanation:
Use one of the equations of motion under gravity.
s = ut + 0.5gt^2 where s = distance, u = initial velocity, g = acceleration due to gravity and t = the time.
So we have:
1000 = 1600t + 0.5* -32*t^2 ( acc due to gravity is negative as we are acting against it).
16t^2 - 1600t + 1000 = 0
t = (1660 +/- sqrt(1600^2 - 4*16*1000) / 32
This gives t = 0.629 , 99.371 seconds.
So the time is above 0.6 seconds (to the nearest tenth) and before 99.4 seconds.

is −4[3(x−7)] and 6(14−2x) equiviant
Answers
Answer:
Yes.
Step-by-step explanation:
Set the equations equal to each other to determine their equality.
-4[3(x - 7)] = 6(14 - 2x)
Distribute the 3 and the 6 into their respective parenthesis.
-4[3x - 21] = 84 - 12x
Distribute the -4 into the brackets.
-12x + 84
Rearrange the equations.
84 - 12x = 84 - 12x
Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.

Find the area I will make you Brainliest (show working) the bottom number is 8 cm where it says liveworksheets
Answers
Answer:
228cm^2
Step-by-step explanation:
Multiply 18cm by 10cm:
18 x 10 = 180cm^2
So we have the area of the biggest/top part: 180cm^2
For the bottom part:
You've said the length of the bottom side is 8cm.
We know the length of the biggest side: 24cm. And we know the length of the opposite side: 18cm. So, to find the length of the missing side, it's simple subtraction:
24cm - 18cm = 6cm
So now we have lengths for 2 sides: 8cm and 6cm.
Multiply these to give the area:
8cm * 6cm = 48cm^2
Add these areas of both shapes together to give total area:
180cm^2 + 48cm^2 = 228cm^2

A golf ball was hit with an initial velocity of 12 meters per second off the ground. The height of the ball after x seconds is modeled by the equation h(x)=-4.8x(x-2.5)
Answers
The ball hits the ground at 0 seconds or 2.5 seconds.
h represents the height of the golf ball after x seconds. The height is given by:
h(x)=-4.8x(x-2.5)
h(x) = -4.8x² + 12x
The time taken for the ball to reach the ground is at h(x) = 0, hence:
0 = -4.8x² + 12x
4.8x² - 12x = 0
x(4.8x - 12) = 0
hence x = 0; or 4.8x - 12 = 0
x = 0; or x = 2.5
Therefore the ball hits the ground at 0 seconds or 2.5 seconds.
