A circle has an area of 49•3.14 square units. What is the diameter of the circle?
Answers
First we will solve for r, radius, and then double it to find the diameter.
153.86 = (3.14)(r)²
49 = r²
√49 = r
7 = r
Now the diameter:
7*2 = 14
So the diameter is 14 units.

Jessique sells handbag for $50 each she spends $4 per handbag for materials and $1000 to rent a store each month write an expression that shows how much profit jessique will earn in 1 month if she sells x amount of handbags
Answers
Answer:
The expression that shows how much profit Jessique will earn in
1 month is ⇒ Profit = 46x - 1000
Step-by-step explanation:
* Lets revise the relation between selling price , cost price and profit
- Profit is the difference between the selling price and the cost price
- Profit = selling price - cost price
- Jessique sells handbag for $50 each
- The selling price of each handbag is $50
- She spends $4 per handbag for materials
- She spends $1000 to rent a store each month
- She sells x amount of handbags in one month
* Lets calculate the cost price of the x handbags in 1 month
∵ She spends $4 per handbag for materials
∴ She spends on the materials of x handbag = 4 × x = 4x
∵ She spends $1000 to rent a store each month
∴ The cost price of x handbags in 1 month = 4x + 1000
∵ She sells x handbags in 1 month
∵ The selling price of 1 handbag is $50
∴ The selling price of x handbags in 1 month = 50 × x = 50x
∵ Profit = selling price - cost price
∴ Profit = 50x - (4x + 1000) ⇒ multiply the bracket by (-)
∴ Profit = 50x - 4x - 1000 ⇒ add like terms
∴ Profit = 46x - 1000
* The expression that shows how much profit Jessique will earn in
1 month is Profit = 46x - 1000
Final answer:
Jessique's profit for selling x handbags in one month is represented by the expression 46x - 1000, where x is the number of handbags sold.
Explanation:
Jessique sells handbags for $50 each. She spends $4 per handbag for materials and $1000 to rent a store each month. To calculate Jessique's profit for selling x handbags in a month, you would subtract both the materials cost and the fixed store rent from her total sales.
The total sales from x handbags is $50 times x, or $50x. The cost of materials for x handbags is $4 times x, or $4x. The fixed store rent is $1000 every month, regardless of how many handbags are sold.
Therefore, to find her profit, the expression is:
Profit = Total Sales - Materials Cost - Fixed Rent
Profit = (50x) - (4x) - 1000
Simplifying this expression, her profit for x handbags in a month would be:
Profit = 46x - 1000

Given the annual interest rate of each, which account will earn the most interest on a $10,000 deposit over 7 years?
Answers
A formula is expressed as d=a(2+kt). Express k in terms of d, a and t
Answers
k = [tex] \frac{d-2a}{at} = \frac{d}{at} - \frac{2a}{at} = \frac{d}{at} - \frac{2}{t} [/tex]
Explanation:
To get the value of k, we will need to isolate it on one side of the equation.
This can be done as follows:
d = a(2+kt)
1- get rid of the brackets using distributive property:
d = a(2+kt)
d = 2a + akt
2- Subtract 2a from both sides of the equation:
d - 2a = 2a + akt - 2a
d - 2a = akt
3- Divide both sides of the equation by "at":
[tex] \frac{d-2a}{at} = \frac{akt}{at} [/tex]
[tex] k= \frac{d-2a}{at} [/tex]
4- We can further simplify the answer as follows:
k = [tex] \frac{d-2a}{at} = \frac{d}{at} - \frac{2a}{at} = \frac{d}{at} - \frac{2}{t} [/tex]
Hope this helps :)
Answer:
[tex]k=\frac{d}{ta}-\frac{2}{t}[/tex]
Step-by-step explanation:
d=a(2+kt)
WE need to solve for k. our aim is to get K alone
d= a(2+kt)
To eliminate 'a' we divide by 'a' on both sides
[tex]\frac{d}{a} = 2+ kt[/tex]
To eliminte 2 we subtract 2 on both sides
[tex]\frac{d}{a}-2 =kt[/tex]
Now to isolate K we divide by 't' on both sides
When we divide a fraction by 't' then we multiply 't' at the bottom
[tex]\frac{d}{ta}-\frac{2}{t}=k[/tex]

The perimeter of the base of the regular quadrilateral pyramid is P = 30 cm. Find the sum of all edges of this pyramid, if the perimeter of a lateral face is 27.5 cm
Answers
.. 2*(27.5 cm) +(1/2)*(30 cm) = 70 cm
The sum of all edges of the regular quadrilateral pyramid depends on the length of the base edges and the height of the pyramid.
Explanation:To find the sum of all edges of the regular quadrilateral pyramid, we need to find the length of the edges. Let's denote the length of the edge of the base by 'a'. Since the base of the pyramid is a regular quadrilateral, all its sides are equal. Therefore, the perimeter of the base is given by P = 4a = 30 cm.
Dividing both sides of the equation by 4, we get a = 7.5 cm.
Since the perimeter of a lateral face is 27.5 cm, the length of each lateral edge is equal to the height of the pyramid. Therefore, the sum of all edges of the pyramid is 4a + 4h, where 'h' is the height of the pyramid.
So, the sum of all edges is 4(7.5 cm) + 4h = 30 cm + 4h.

The rest of the students in the play are from Mr. Logan’s class and Ms. Gardner’s class.
Mr. Logan has 23 students in his class, and 7 of them are in the play. There are 4 more students from Ms. Gardner’s class than from Mrs. Cho’s class in the play.
The number of students in the play from Mr. Logan’s class is greater than the number from Mrs. Cho’s class and fewer than the number from Ms. Gardner’s class.
In all, 30% of the students in these three classes are in the play.
Show or explain why there must be exactly 23 students in Ms. Gardner’s class. As part of the explanation, determine how many students from Ms. Gardner’s class are in the play.
Answers
There should be 23 students from Ms. Gardner’s class in the play.
To determine why there must be exactly 23 students in Ms. Gardner's class and to find out how many students from Ms. Gardner's class are in the play, let's break down the problem step-by-step.
Define Variables:- Let L be the number of students in Mr. Logan's class.
- Let G be the number of students in Ms. Gardner's class.
- Let C be the number of students in Mrs. Cho's class.
- Let [tex]P_L[/tex] be the number of students from Mr. Logan's class in the play.
- Let [tex]P_G[/tex] be the number of students from Ms. Gardner's class in the play.
- Let [tex]P_C[/tex] be the number of students from Mrs. Cho's class in the play.
Given Information:- L = 23
- [tex]P_L[/tex] = 7
- There are 4 more students from Ms. Gardner's class in the play than from Mrs. Cho's class: [tex]P_G[/tex] = [tex]P_C[/tex] + 4
[tex]P_G[/tex]
- The number of students in the play from Mr. Logan's class is greater than the number from Mrs. Cho's class and fewer than the number from Ms. Gardner's class: [tex]P_C[/tex] < 7 < [tex]P_G[/tex]
- 30% of the students in these three classes are in the play.
Calculate Total Students and Students in the Play:- Total students in these three classes: L + G + C
- Total students in the play: [tex]P_L[/tex] + [tex]P_G[/tex] + [tex]P_C[/tex]
30% of the Students are in the Play:
- 0.30 (L + G + C) = [tex]P_L[/tex] + [tex]P_G[/tex] + [tex]P_C[/tex]
Substitute L = 23 and [tex]P_L[/tex] = 7:0.30 (23 + G + C) = 7 + [tex]P_G[/tex] + [tex]P_C[/tex]
Using [tex]P_G[/tex] = [tex]P_C[/tex] + 4 :
0.30 (23 + G + C) = 7 + ([tex]P_C[/tex] + 4) + [tex]P_C[/tex]
0.30 (23 + G + C) = 7 + [tex]P_C[/tex] + 4 + [tex]P_C[/tex]
0.30 (23 + G + C) = 11 + 2[tex]P_C[/tex]
Simplify the equation:0.30 (23 + G + C) = 11 + 2[tex]P_C[/tex]
0.30 × 23 + 0.30G + 0.30C = 11 + 2[tex]P_C[/tex]
6.9 + 0.30G + 0.30C = 11 + 2[tex]P_C[/tex]
Rearrange the equation:0.30G + 0.30C = 11 + 2[tex]P_C[/tex] - 6.9
0.30G + 0.30C = 4.1 + 2[tex]P_C[/tex]
Divide by 0.30:G + C = [tex]\frac{4.1 + 2P_C}{0.30}[/tex]
G + C = [tex]\frac{4.1}{0.30} + \frac{2P_C}{0.30}[/tex]
G + C = [tex]\frac{41}{3} + \frac{20}{3}P_C[/tex]
G + C = [tex]\frac{41 + 20P_C}{3}[/tex]
From the constraints [tex]P_C[/tex] < 7 < [tex]P_G[/tex] and [tex]P_G[/tex] = [tex]P_C[/tex] + 4:[tex]P_G[/tex] = 7
[tex]P_C[/tex] = [tex]P_G[/tex] - 4 = 7 - 4 = 3
So,
G + C = [tex]\frac{41 + 20 \cdot 3}{3} = \frac{41 + 60}{3} = \frac{101}{3}[/tex]
G + C = 33.67
Since G and C must be integers and they add up to 33.67, we need to check for plausible values of G and C. However, considering our assumptions and given constraints, we should use consistent integer values:
For:
[tex]P_G[/tex] = 7
[tex]P_C[/tex] = 3
Using the total students equation:0.30(23 + G + C) = 7 + 7 + 3
0.30(23 + G + C) = 17
Thus:
23 + G + C = [tex]\frac{17}{0.30}[/tex]
23 + G + C = 56.67
So:
G + C = 56.67 - 23 = 33.67
Given [tex]P_C[/tex] < 7 < [tex]P_G[/tex], by resolving as integers:
G = 23
C = 11
Thus, Ms. Gardner's class must have 23 students.
Jackson is playing a video game that has 3 castles to conquer within each level. Jackson has completed 5 levels so far. If x represents the number of remaining levels to complete, which of the following equations can be used to find the total number of castles Jackson will have conquered once he completes the final level?
Answers
The equation to find the total number of castles conquered by Jackson is 15 + 3x, where x represents the remaining levels. Jackson has conquered 15 castles in 5 levels and will conquer 3 more for each additional level he completes.
Explanation:The question relates to creating an equation to find the total number of castles Jackson will have conquered after completing all levels in a video game. Jackson has completed 5 levels, and there are 3 castles within each level. If x represents the remaining levels to complete, we can create the equation by considering the total number of castles conquered in the levels completed (5 levels × 3 castles/level = 15 castles) and adding it to the castles that will be conquered in the remaining levels (x levels × 3 castles/level). The equation representing the total number of castles Jackson will have conquered once he completes the final level is:
Total castles = (5 × 3) + (x × 3) = 15 + 3x
As a separate example unrelated to Jackson's equation, there is the classical problem involving grains of rice and a chessboard that demonstrates exponential growth. In this example, one grain of rice is placed on the first square of a chessboard, and the number of grains is doubled on each subsequent square. By the 64th square, you are placing a very large number of grains, and the total number minus one grain would be 264 - 1. However, the actual number of grains needed is a separate calculation from the equation for Jackson's video game question.

Answers
Explanation:
The mean is found by adding together all of the data points and then dividing by the number of data points. For Doctor 1, (32+20+22+29+15+17+18+1+1+2+3+7+9)/13 = 176/13 = 13.54.
For Doctor 2, (35+20+20+22+23+26+13+17+2+2+3+9)/12 = 192/12 = 16.
The median is the middle number in the data set after it has been ordered from least to greatest. The stem-and-leaf plot organizes it, so we find the middle value.
For Doctor 1, 15 is in the middle.
For Doctor 2, the middle is between 26 and 13: (26+13)/2 = 39/2 = 19.5
Answer:
The mean of the ages of Doctor 1's patients is 13.54 and the median is 15. The mean of the ages of Doctor 2's patients is 16 and the median is 19.

The expression can be simplified using the distributive property, but it is not in its simplest form, Option A is correct.
What is Expression?An expression is combination of variables, numbers and operators.
The expression 6x + (9+3x) is in the distributive property.
To see why, we can apply the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. In this case, we have:
6x + (9+3x) = 6x + 9 + 3x
Here, the expression 6x is being distributed over the parentheses, which contain 9 and 3x. We can combine the constants 6x and 9, as well as the like terms 6x and 3x, using the commutative and associative properties of addition:
6x + 9 + 3x
= 6x + 3x + 9
= (6x + 3x) + 9
= 9x + 9
So, the expression can be simplified using the distributive property, but it is not in its simplest form.
