Answer: 6 boxes. average 45 each.
Step-by-step explanation:
The mean of a dataset if the average of the dataset.
The new mean mass of the remaining boxes is 44 kg
From the question, we have:
[tex]\mathbf{\bar x = 45}[/tex] --- mean of 6 boxes
The mean of a dataset is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
So, we have:
[tex]\mathbf{45 = \frac{\sum x}{6}}[/tex]
Multiply by 6
[tex]\mathbf{45 \times 6= \sum x}[/tex]
[tex]\mathbf{\sum x = 270}[/tex]
One of the boxes is 50 kg.
So, the mass of the remaining boxes is:
[tex]\mathbf{Mass = 270 - 50}[/tex]
[tex]\mathbf{Mass = 220}[/tex]
The mean of the remaining boxes is:
[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]
[tex]\mathbf{\bar x = \frac{220}{5}}[/tex]
[tex]\mathbf{\bar x = 44}[/tex]
Hence, the new mean mass of the remaining boxes is 44 kg

Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2 feet. What is the total length of fending Mark needs to
surround all 4 gardens?
Mark needs
feet of fencing
v
Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula
P = 2(L) + 2(W)
Total Length of the garden =
=
Length = 18.5 feet
Total width of the garden =
=
Width = 9.0 feet
Perimeter of the garden = 18.5 + 9 = 27.5 feet
Mark wants to fence 4 garden
Therefore, 27.5 × 4 = 110 feet.
Mark needs 110 ft. fencing to surround all 4 gardens.

Members of the theater club sold tickets for the spring
musical. On Friday night, they made $125 in presales a
sold 120 tickets at the door. For the Saturday night sho
they earned $180 in presales and sold 110 tickets at the
door, If the theater club earned the same amount each
night, what is t, the cost per ticket?
Answer:
C. 125 + 120x = 180 + 110x
t = $5.5
Step-by-step explanation:
A.125t + 120 = 180t + 110
B. 120t + 110t = 125 + 180
C. 125 + 120t = 180 + 110t
D. 125 - 120t = 180 - 110t
Friday
$125 + 120t
Saturday
110t + 180
equate Friday and Saturday
125 + 120t = 110t + 180
Collect like terms
125 - 180 = 110t - 120t
-55 = -10t
Divide both sides by -10
t = -55 / -10
= 5.5
t = $5.5

If a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second, how long will it take the football to hit the ground? Use the equation h = −16t2 + 6t + 4. Round your answer to the nearest hundredth.
0.72
0.65
0.35
0.27
Given:
The height of ball is represented by the equation is
[tex]h=-16t^2+6t+4[/tex]
To find:
The time taken by ball to hit the ground.
Solution:
First we need to find the zeroes of the given equation. So, for zeroes h=0.
[tex]-16t^2+6t+4=0[/tex]
Here, [tex]a=-16,b=6,c=4[/tex]. Usingquadratic formula, we get
[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]t=\dfrac{-6\pm \sqrt{6^2-4(-16)(4)}}{2(-16)}[/tex]
[tex]t=\dfrac{-6\pm \sqrt{36+256}}{-32}[/tex]
[tex]t=\dfrac{-6\pm \sqrt{292}}{-32}[/tex]
[tex]t=-\dfrac{-6+ 17.088}{-32},\dfrac{-6+ 17.088}{-32}[/tex]
[tex]t=0.7215,-0.3465[/tex]
Time cannon be negative. So, at t=0.7215 the ball will hit the ground. Time taken by ball to hit the ground is
[tex]t=0.7215-0[/tex]
[tex]t=0.7215[/tex]
Round your answer to the nearest hundredth.
[tex]t\approx 0.72[/tex]
So, the ball will hit the ground after 0.72 seconds.
Therefore, the correct option is A.

0.72

-2x-10x+12=18
PLEASE EXPLAIN HOW YOU GOT THE ANSWER
Answer:
x = - 0.5
Step-by-step explanation:
you have to simplify the equation so
[tex] - 2x - 10x + 12 = 18 \\ - 12x + 12 = 18 \\ - 12x = 18 - 12 \\ - 12x = 6 \\ x = \frac{6}{ - 12} \\ x = - 0.5[/tex]
Answer:
X= -1/2 Hope this helps <3
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−10x+12=18
Step 1: Simplify both sides of the equation.
−2x−10x+12=18
−2x+−10x+12=18
(−2x+−10x)+(12)=18(Combine Like Terms)
−12x+12=18
−12x+12=18
Step 2: Subtract 12 from both sides.
−12x+12−12=18−12
−12x=6
Step 3: Divide both sides by -12.

1.4 has 2 significant digits as a result of which rule? a. All nonzero numbers are significant. b. Zeros between nonzero digits are significant. c. Final zeros after the decimal point are significant. d. Zeros used solely for spacing the decimal point are not significant.
Answer:
All non zero digits count in significant digits.
(a) is correct option.
Step-by-step explanation:
Given that,
1.4 has 2 significant digits.
We know that,
Significant digits :
All non zero digits count in significant digits.
All zero which is present in between two significant digits it is also significant.
Leading zero is not count as significant.
Trailing zero is count as significant.
We need to find 1.4 has 2 significant digits as a result of which rule
Using given rules
1.4 has 2 significant digits it is follows the rule of all non zero digits count in significant digits.
Hence, All non zero digits count in significant digits.
(a) is correct option.

Hailey cuts a 7-inch square piece of plywood for a birdhouse. She rotates the piece 90° counterclockwise. What is the length in inches of each side of the piece of plywood after the rotation?
Can someone please help me ASAP!!
Answer:
[tex]\huge\boxed{7\ \text{inches}}[/tex]
Step-by-step explanation:
As I mentioned earlier with a single side (line), rotations do not change the size of something. Only dilations do that. This goes for both lines AND shapes.
However, if the question said she dilated the piece, then yes, the length in inches would be different. However, rotation just changes the position and nothing happens to the length.
