Answer:
x > 2 or x < −4
Step-by-step explanation:
Let's solve your inequality step-by-step.
|3x + 3| −5 > 4
Step 1: Add 5 to both sides.
|3x + 3| −5 + 5 > 4 + 5
|3x + 3| > 9
Step 2: Solve Absolute Value.
|3x + 3| > 9
We know either3x + 3 > 9 or 3x + 3 < −9
3x + 3 > 9(Possibility 1)
3x + 3 −3 > 9 −3(Subtract 3 from both sides)
3x > 6
3x > 6 (Divide both sides by 3)
3 3
x > 2
3x + 3 < −9(Possibility 2)
3x + 3 −3 < −9 −3(Subtract 3 from both sides)
3x < −12
3x < -12 (Divide both sides by 3)
3 3
x < −4

A cube has a volume of 197 meters cubed (197 m3) What is the approximate value of one edge of the cube? The approximate value of one edge of the cube is meters. Round your answer to the nearest hundredth. What is the approximate area of one face of the cube? The approximate area of one face of the cube is meters. Round your answer to the nearest hundredth.
The edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively
How to determine the valueThe formuka for the volume of a cube is expressed as;
Volume = a^3
Where 'a' is the length of it's edge
From the information given, we have that the volume of the cube has a value of 197 cubic meters.
Now, substitute the value of the volume
We have;
197 = a^3
Take the cube root of both sides
a = 5. 82 meters
The formula for area of the face of a cube is given as;
Area = 6a ^2
Area = 6(5.82)^2
Area = 6(33. 85)
Area = 203 square meters
Thus, the edge length and area of the face of the cube are 5. 82 meters and 203 square meters respectively

a swimming pool has two pipes coming in. one fills the pool in four hours, the other in six hours. an outlet pipe empties the pool in five hours. the outlet pipe is accidentally left open. in how many hours is the pool full?
The pool is full for 4 hrs.
Add the rates of filling of the 2 filling pipes and
subtract the rate of draining of the emptying pipe;
1st pipe's rate: ( 1 pool filled ) / ( 3 h);
2nd pipe's rate: ( 1 pool filled ) / ( 6 h );
3rd pipe's rate of emptying: ( 1 pool emptied ) / ( 4 h);
Let t = the time in hrs to fill the pool with all 3 pipes open
1/3+16-1/4 = 1/t;
Multiply both sides by 24t;

The perimeter is units. The area is
squareunits.
The perimeter of the polygon will be 20 units and the area will be 21 square units.
From the given vertices a rectangle will be formed. A rectangle is a closed figure in which each interior angle is a right angle. The Perimeter of the rectangle can be given by formula 2(l + b) and the area is given by l×b where l is the length and b is breadth of rectangle. Now from the given points the dimensions of rectangle will follow the order W (5, -1), X (5, 6), Z (2, 6) and Y (2, -1).
The length of the rectangle is given by l = √ (6 + 1) ² + (5 - 5) ²
l = √49
l = 7 units
The breadth of the rectangle is given by b = √ (6 - 6) ² + (2 - 5) ²
b = √9
b = 3 units
Now, the perimeter of rectangle = 2 (l + b)
P = 2(7 + 3)

The angle shown has the same measure as an angle drawn on paper. Order the steps for copying the angle from the paper using a compass and straightedge.
The order of the steps for copying the angle from the paper using a compass and a straight edge are;

A particular antibiotic is eliminated from the blood with a half-life of 16 hours. how many hours does it take for 100-milligram dose to decrease to 30-milligrams in the blood?
Using the decay formula, the particular antibiotic with half-life of 16 hours, will decrease to 30-milligrams in the blood after 27.79 hours.
We can use the decay formula to solve the problem:
A(t) = A(0) . (0.5)^(t/T)
Where:
A(t) is the remaining quantity at time t
A(o) is the initial quantity
t is the time interval
T is the half-life rate
In the given problem:
A(0) = 100 milligram
T = 16 hours
A(t) = 30 milligram
We need to find t such that the remaining quantity of this antibiotic is 30 mg.
Substitute the given parameters into the formula:
A(t) = A(0) . (0.5)^(t/T)
30 = 100 . (0.5) ^(t/16)
Taking the logarithm:
log (30) = log [100 . (0.5) ^(t/16)]
Use the logarithm property, log(A.B) = log A + log B
log (30) = log (100) + log [(0.5) ^(t/16)]
Use the logarithm property, log(Aⁿ) = n.log A
log (30) = log (100) + (t/16) . log (0.5)
log (30) = 2 + (t/16) . log (0.5)
(t/16) . log (0.5) = log (30) - 2
t/16 = 1.737
t = 1.737 . (16) = 27.79 hours

29) A company planned to donate 640 bags of groceries, 320 cases of bottled water, and 800 small toys to a
local relief center. Suppose that the number of bags of groceries, cases of bottled water, and small toys are to be
placed in boxes with the same number of each good in each box. For instance, you could place 10 bags of
groceries and 5 cases of water in each of 64 boxes, but that would require 12.5 toys per box-oops! To be as
efficient as possible, assume that the company wants to use as few boxes as possible and must have a whole
number of groceries, water, and toys in each box.
a) How many boxes are needed? b) What are the contents of each box?
160 boxes needed to pack these items
Therefore contents in each box have 4 bags of groceries, 2 cases of bottled water, and 5 toys.
Given no of groceries bags = 640
number of cases of bottled water = 320
number of small toys = 800
We have to find out how many boxes are needed and the contents of each box.
(i) How many boxes are needed:
To do this we need to find the greatest common factor of these three items
as
640 - 2⁷ * 5
320 - 2⁶ * 5
800 - 2³ * 5²
GCF = 2⁵ * 5 = 160
Therefore 160 boxes needed to pack these items
(ii) Contents of each box:
No of bags of groceries in each box = 640 / 160 = 4
No of cases of bottled water = 320 / 160 = 2
No of toys in each box = 800 / 160 = 5
Therefore, contents in each box have 4 bags of groceries, 2 cases of bottled water, and 5 toys.

What is the student error in the multiplication below?
Multiply the ones: 957 times 23 = 2871. Above the 9 in 957 is 1, above the 5 in 957 is 2.
Multiply the tens: 957 times 23 = 2871. 2871 + 1914 = blank. Above the 9 in 957 is 1, above the 5 in 957 is 1.
Answer:
When multiplying the tens, the student didn't use the 0 place holder for the ones place.
Step-by-step explanation:
When using or doing long multiplication the answer was correct (2871) BUT before multiplying the tens, a zero should be placed in the ones place of the results. So, the tens should be 19140
2871+19140=22011
Answer: 1) When multiplying the ones, the student did not carry over a ten to the next place in the first multiplication.
2) When multiplying the ones, the student should have calculated 3 times 2 plus 5 as 11 and placed a 1 in the tens place.
3) When multiplying the tens, the student did not use the 0 place holder for the ones place.
4) When multiplying the tens, the student should have calculated 2 times 1 plus 9 as 11 and used a 1 should in the hundreds place.
Answer:
The correct option is;
4) When multiplying the tens, the student did not use the 0 place holder for the ones place
Step-by-step explanation:
Here we have when doing long multiplication, the student correctly multiplies the ones as 2871, however, before commencing multiplication of the tens, a 0 should be placed in the ones place of the result as a place holder such that the outcome of the multiplication of the tens should be;
19140
Hence, the correct result should be 2871 + 19140 = 22011
The correct option is therefore, that "When multiplying the tens, the student did not use the 0 place holder for the ones place."

In reality, the lateral face VAB is an isosceles triangle with a 14-length base and 25-length legs. This triangle's altitude must cut over angle V and the base, forming a right triangle with a hypotenuse that is 25 inches long and a short leg that is 7 inches long. We can calculate the altitude, which is also the slant height of the pyramid, using the Pythagorean theorem.
s.h. = alt. = √(252 - 72) = 24
Now, by adding the pyramid's height and half of its base, we may utilize this slant height as the hypotenuse of another right triangle.
We look at a regular octagon to identify half the base. You'll see that four of the sides are horizontal or vertical, while the other four are at an angle of 45 degrees to the first four. So, in this example, 14 + 28/2 = 14 + 142, the distance between parallel sides of a regular octagon would be equal to s + 2s/2.
hence, the base's half would equal 7 + 72.
The height of the pyramid and the dihedral angle with the base are both provided by this right triangle.
