3. At a bargain store, Tanya bought 3 items that each cost the same amount. Tony bought 4 items that each cost the same amount, but each was $2.25 less than the items that Tanya bought. Both Tanya and Tony paid the same amount of money. What was the individual cost of each person's items? (a) Write an equation. Let x represent the cost of one of Tanya's items. (b) Solve the equation. Show your work. (c) Check your solution. Show your work. (d) State the solution in complete sentences. Answer:
3x = 4(x-2.25)
3x = 4x-9
add 9 to both sides
3x+9 =4x
subtract 3 x from each side
x=9
Tonya's items were $9 each
Tony's items were 9-2.25 = 6.75 each
check:
9*3=27
4 *6.75 = 27

a square pyramid and a cube have the same bases and volumes. How are their heights related? Explain.
A square pyramid's height is three times the side of the base of a cube if they have the same base and volume, due to their differing volume formulas.
If a square pyramid and a cube have the same base and volume, the relationship between their heights can be determined using the formulas for their volumes. The volume of a cube is given by [tex]V = s^3,[/tex] where s is the length of a side of the cube's base. The volume of a square pyramid is [tex]V = (1/3) * b^2 * h,[/tex] where b is the length of the base side and h is the pyramid's height. Since both have the same volume, we can set these equations equal to each other and solve for h.
Setting the volumes equal: [tex]s^3 = (1/3) * s^2 * h,[/tex] simplifying to h = 3s. Thus, the height of the pyramid is three times the side of the base of the cube. This is because a cube's volume grows as a cube of its side length, while a pyramid's volume is one third of the base area times the height. Therefore, since they have the same volume, the height of the pyramid must be three times larger to compensate for the 1/3 factor in its volume formula.

the probability of picking a red marble from a bag of 30 marbles is 1/5. how many blue marbles must be removed from the bag to increase the probability to 1/4
To increase the probability from 1/5 to 1/4, we need to remove 24 blue marbles from the bag.
Explanation:To increase the probability from 1/5 to 1/4, we need to find the number of blue marbles that need to be removed. Let's assume there are x blue marbles in the bag. Initially, the total number of marbles in the bag is 30, and the probability of picking a red marble is 1/5. This means that (30 - x)/30 = 1/5. Solving this equation, we get x = 24. Therefore, 24 blue marbles need to be removed from the bag to increase the probability to 1/4.

Because the initial probability of picking a red marble from 30 marbles is 1/5, there are 6 red marbles in the bag. If we want to increase the probability of drawing a red marble to be 1/4, we need to reduce the total number of marbles in the bag to 24. So, we must remove 6 non-red marbles, which could be blue.
Explanation:The subject of your question is probability in Mathematics. Initially, we have 30 marbles, and the probability of picking a red one is 1/5. So, there are 1/5 * 30 = 6 red marbles in the bag. Thus, the bag also contains 24 non-red marbles, which can be blue or other colors.
Next, we want the probability of picking a red marble to be 1/4. Since the number of red marbles will remain the same, we need to change the total number of marbles in the bag. If 'x' is the number of marbles in the bag, then 6/x = 1/4, which means x = 24. Since initially we had 30, to get to 24 we need to remove 6 marbles.
Therefore, if we remove 6 blue marbles (or any non-red marbles), the probability of picking a red marble will increase to 1/4.

Answer:
Multiply the Rate by the Time
Step-by-step explanation:
Hiya! So you would multiply R(rate) by T(time) Then you would divide by I(interest) and you should get your answer for P(principle)
Ex 24= P x 0.04 x 3 0.04 x 3= 0.12 24 divided by 0.12 = 200 So 200= P

the length of a picture frame is 3 inches greater than the width. The perimeter is less than 52 inches. Describe the dimensions of the frame.
To describe the dimensions of the frame, we can represent the width as x inches and the length as (x+3) inches. The perimeter is less than 52 inches. We can solve an inequality using this information to find the possible values for the width.
Explanation:To describe the dimensions of the picture frame, let's represent the width of the frame as x inches. According to the information given, the length of the frame is 3 inches greater than the width, so it can be represented as (x+3) inches. The perimeter of a rectangle is given by the formula: Perimeter = 2(width + length). Since the perimeter is less than 52 inches, we can form the following inequality: 2(x + (x+3)) < 52. Solving this inequality will give us the range of possible values for the width, and we can then determine the corresponding length of the frame.

5._4 - (_.8_) = -3.61
fill in the blanks please !!
Answer:
[tex]5.24-8.85=-3.61[/tex]
Step-by-step explanation:
We have been given an equation. We are asked to fill in the blanks for the given equation.
5._4 - (_.8_) = -3.61
We will find each part separately as:
For hundredths digit:
[tex]4-?=-1[/tex]
[tex]4-4-?=-1-4[/tex]
[tex]-?=-5[/tex]
[tex]?=5[/tex]
So hundredths digit would be 5.
Tenth digit:
[tex]?-8=-6[/tex]
[tex]?-8+8=-6+8[/tex]
[tex]?=2[/tex]
Ones digit:
[tex]5-?=-3[/tex]
[tex]5-5-?=-3-5[/tex]
[tex]-?=-8[/tex]
[tex]?=8[/tex]
Substitute the values in given equation.
5.24 - (8.85) = -3.61
We can verify our answer by subtracting 8.85 from 5.24.
[tex]5.24-8.85=-3.61[/tex]
Therefore, our equation would be [tex]5.24-8.85=-3.61[/tex].
