Answer:
Problem 1. Answer: D
Problem 2. Answer: A
Problem 3. Answer: C
Problem 4. Answer: D
Step-by-step explanation:
Problem 1:
A pack is targeted to weigh 9.25 oz.
A pack can be up to 0.23 oz off, either over or under weight.
The pack cannot weigh less than 9.25 oz - 0.23 oz or more than 9.25 oz + 0.23 oz.
The following compound inequality represents the rejected weights.
x < 9.25 - 0.23 or x > 9.25 + 0.23
Subtract 9.25 from both sides of both inequalities.
x - 9.25 < -0.23 or x - 9.25 > 0.23
Change to an absolute value inequality.
|x - 9.25| > 0.23
x - 9.25 < -0.23 or x - 9.25 > 0.23
x < 9.02 or x > 9.48
Problem 2:
Almond trees produce 12a
Macadamia nut trees produce 8m
Yield is 250

1000 m = 1 km
60 sec = 1 min
60 min = 1 hr
8.8 m/s * (1 km)/(1000 m) * (60 s)/(1 min) * (60 min)/(1 hr) =
= 31.68 km/h

On the model scale drawing, approximately how far should each edge of the bed be from its own corner of the wall? Use complete sentences to explain your reasoning.
Solution:
Considering room to be in the shape of Cuboid as well as the Bed to be in the shape of Cuboid.
Dimensions of Room
Let Length of cuboid which is in the shape of room = L
Breadth of cuboid which is in the shape of room = B
Height of cuboid which is in the shape of room = H
Considering, L>B>H
Dimension of Bed
Length=[tex]\frac{L}{6}[/tex] units
Breadth=[tex]\frac{B}{4}[/tex] units
Height=[tex]\frac{H}{6}[/tex] units
Taking one corner at origin i.e (0,0,0)
You can keep your bed at any place inside the room, but you want your bed to be at that place inside the room where the window is located so that proper ventilation and sunlight can enter your room.
Taking bed to be in the middle of room near the window and considering it's upper face
Distance from one corner i.e from length= B- [tex]\frac{B}{4}[/tex]=[tex]\frac{3B}{4}[/tex] Units
Distance from other corner= 0 Units
Distance from Breadth of one side of wall= [tex]\frac{L}{3}[/tex] units
Distance from one corner i.e from Breadth =L - [tex]\frac{L}{3}[/tex]-[tex]\frac{L}{6}[/tex]= [tex]\frac{L}{2}[/tex]
Distance from floor i.e surface=[tex]\frac{H}{6}[/tex] units
Distance from Ceiling= H -[tex]\frac{H}{6}[/tex] = [tex]\frac{5 H}{6}[/tex] units
To find the distance each bed edge should be from the corner in a scale drawing, determine the scale used (such as 1 inch = 6 feet), convert actual bed dimensions using the scale, and ensure measurements on the drawing are precise and noted with the correct line types.
To determine how far each edge of the bed should be from its own corner of the wall in a scale drawing, first establish the scale being used for the model. For example, if the scale is 1 inch = 6 feet, convert the actual dimensions of the bed into the scale size by using ratios that compare the scale distance to the actual distance. If the actual bed is 6 feet long, then the length on the scale model would be 1 inch. When recording measurements, both the actual size and the scale size should be clearly marked to prevent confusion. It is important to use correct line types and to make all the drawings to exact measurements within the constraints of the paper size.
For consistent and accurate representation, the edges of the bed should be measured from the corner of the walls based on the determined scale. This involves calculating the distance of the bed from the wall in actual size, then converting that distance to the scale model size. Pay attention to significant figures and the choice of units (inches, feet, centimeters, meters) to maintain precision in your scale drawing.

In 1983 the composition of pennies in the United States was changed due, in part, to the rising cost of copper. Pennies minted after 1983 weigh 2.50 grams while the earlier copper pennies weigh 3.11 grams. a. A roll of pennies contains 50 pennies. If a particular roll of pennies weighs 138.42 grams, how many of the earlier copper pennies and how many of the after 1983 pennies does this roll contain? b. Suppose you measure a roll of pennies on a scale which only reads the weight to the nearest gram. The scale says that the roll of pennies weighs 131 grams. What can you conclude about the pennies in this roll? What if the roll weights 134 grams? Explain.
Answer:
Solution for (a)
Earlier Copper pennies are 22.
After 1983 pennies are 28.
Step-by-step explanation:
Pennies minted after 1983 weigh 2.50g
Earlier copper pennies weigh 3.11g
A roll of pennies contains 50 pennies.
A particular roll of pennies weighs 138.42g
Let the number of pennies minted after 1983 be x and;
Earlier copper pennies be 50 - x
2.50x + 3.11(50 - x) = 138.42
Opening the brackets gives;
2.5x + 155.5 - 3.11x = 138.42
Solving like terms together gives;
-0.61x = -17.08
Dividing through gives;
x = 28
So there are 28 after 1983 pennies and;
50 - 28 = 22 earlier pennies.
On Monday, Harry had 75\%75% as many toys as Teddy did. On Tuesday, after Harry acquired 3232 more toys and Teddy acquired 15\%15% more than he had on Monday, Harry had as many toys as Teddy did. How many toys did Harry have on Monday?
Answer:
60
Step-by-step explanation:
We can first define the variables as hh for the number of Harry's toys on Monday and tt for the number of Teddy's toys on Monday.
We know that on Monday, Harry had 75\%75% as many toys as Teddy, so we can write the following equation:
\qquad h=0.75th=0.75t
Hint #2
When we add 3232 toys to Harry's collection, we get h+32h+32. We can also make an adjustment to Teddy's collection, as he acquired 15\%15% more. We can represent that as 1.15t1.15t, as we should add 15\%15% to 100\%100% to get a percent increase.
Now let's make an equation for Tuesday:
\qquad h+32=1.15th+32=1.15t
Hint #3
We also know that h=0.75th=0.75t from the first equation, so we can substitute that in.
\qquad 0.75t + 32 = 1.15t0.75t+32=1.15t
Let's solve by first subtracting 0.75t0.75t from both sides.
\qquad 32 = 0.4t32=0.4t
We can then divide by 0.40.4 to solve for tt, and when we do that, we find that t=80t=80.
Hint #4
Since t=80t=80, we must substitute it into another equation to find hh (the number of toys Harry had on Monday). Let's pick the first equation.
\qquad h=0.75th=0.75t
\qquad h=0.75(80) = 60h=0.75(80)=60
Hint #5
Harry had 60 toys on Monday.

___cm
PLZ HELP ME I WILL MARK U as the brainliest answerrrrr I cannot get this wrong PLZZ
The liquid height in the new cylinder will be 4 cm after the volume of liquid from the original cylinder is transferred.
Explanation:In the context of this problem, we are dealing with the concept of the volume of a cylinder. The volume of a cylinder is given by the formula V=πr²h, where r is the radius of the base and h is the height of the cylinder. The given volume in the problem is 36π cm³ and the radius of the second cylinder is 3 cm. We will use the volume formula to find the height.
We know that V=36π cm³ and r=3 cm. Substituting these values into the volume formula, we get 36π=π(3)²h. Simplifying the equation gives us 36π=9πh. Dividing both sides by 9π, we arrive at the solution, h=4 cm. Therefore, the height of the liquid in the new cylinder will be 4 cm.

Jay is 4 years younger than three times Tamia's age. Jay is 20 years old. How old is Tamia?
Final answer:
To find Tamia's age, an equation was set up based on the relationship between Jay and Tamia's ages. Jay is 20 years old and 4 years younger than three times Tamia's age. Solving the equation shows that Tamia is 8 years old.
Explanation:
Jay is 4 years younger than three times Tamia's age. Given that Jay is 20 years old, we can use this information to find out how old Tamia is. Let's denote Tamia's age as T. The relationship between their ages can be represented by the equation: Jay's age = 3 × Tamia's age - 4. Since Jay's age is 20, we can substitute this into the equation, giving us 20 = 3T - 4.
To solve for T, we first add 4 to both sides of the equation, which gives us 24 = 3T. Next, we divide both sides by 3 to find Tamia's age, resulting in T = 8. Therefore, Tamia is 8 years old.
This problem was solved by setting up an equation based on the relationship described between Jay and Tamia's ages, then using basic algebraic steps to solve for Tamia's age.

We will call the unknown angle in the triangle y. Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4. Substitute x=56 into the equation.
2(56)+4
112+4
116
