a jigsaw puzzle has edge pieces and inside pieces. the ratio 3:22. there are 924 inside pieces. calculate the total number of pieces in the puzzle
The jigsaw puzzle has a total of 1050 pieces, with 126 edge pieces and 924 inside pieces, based on the ratio 3:22 provided in the question.
To calculate the total number of pieces in the jigsaw puzzle, we need to use the given ratio of edge pieces to inside pieces, which is 3:22. If there are 924 inside pieces, and the ratio of edge pieces to inside pieces must remain constant, we can set up a proportion where the number of edge pieces is represented by x and the number of inside pieces by 924.
3:22 = x:924
To find the value of x, we can cross-multiply:
3 * 924 = 22 * x
This gives us :
2772 = 22x
Now, we can solve for x by dividing both sides of the equation by 22:
x = 2772 / 22
x = 126
This means there are 126 edge pieces. To find the total number of pieces in the jigsaw puzzle, we add the edge pieces to the inside pieces:
Total pieces = edge pieces + inside pieces = 126 + 924 = 1050
Plot the x- and y-intercepts to graph the equation. y=1/3x−1.
Answer:
The graph of given equation is shown below.
x-intercept is 3 and y-intercept is -1.
Step-by-step explanation:
The given function is
[tex]f(x)=\frac{1}{3}x-1[/tex]
We need to draw the graph of given equation.
At x=0,
[tex]f(0)=\frac{1}{3}(0)-1=-1[/tex]
So, y-intercept is -1.
Equate f(x)=0 to find x-intercept.
[tex]\frac{1}{3}x-1=0[/tex]
[tex]\frac{1}{3}x=1[/tex]
Multiply both sides by 3.
[tex]x=3[/tex]
So, x-intercept of the line is 3.

explain the. different ways that u can use multiplication to estimate. and solve. division problems
Answer:
Instead of divide the dividend by the divisor to get a quotient, you can estimate an approximate quotient and then multiply it by the dividend. If the result is greater than the divisor, then your estimated quotient was greater than the actual quotient, in the case that the result is lower than the divisor, then your estimated quotient was lower than the actual quotient. After that you proceed to estimate again the quotient. For example:
First approximation:
192/12 ≈ 14
12*14 = 168 < 192
Second approximation:
192/12 ≈ 20
12*20 = 240
So, the answer is between 14 and 20
Third approximation:
192/12 ≈ 16
12*16 = 192
Then, 16 is the correct answer

An architect is designing a new windmill with four sails. In his sketch the sails center of rotation is the origin (0,0) and the top of one sails point T, has a coordinates (6,-2). He wants to make another sketch that shows the windmill after sails have rotated 180* degrees about their center of rotation. What would be the coordinates of T?
The coordinates of T are (-6,2).
The sails center of rotation is the origin (0,0)
The top of one sails point T(6,2).
What is the rotation?The action or process of rotating on or as if on an axis or center.
A 180 degree rotation make you turn (x, y) into (-x, -y),
so the point turn (6, -2), into (-6, 2).
Therefore the coordinates of T are (-6,2).

Kendrick adds 3/4cup of chicken stock to a pot. Then he takes 3/4 cup of stock out of the pot. What is the overall increase or decrease in the amount of chicken stock in the pot?
There is no net change in the amount of chicken stock in the pot.
To determine the overall change in the amount of chicken stock, we need to compare the amount added to the amount removed. Kendrick adds 3/4 cup of chicken stock to the pot, and then he takes out 3/4 cup of chicken stock from the pot.
Using a simple calculation:
Initial stock added: 3/4 cupStock removed: 3/4 cupOverall change = 3/4 cup - 3/4 cup = 0 cupsTherefore, the overall increase or decrease in the amount of chicken stock in the pot is zero. There is no net change in the amount of chicken stock in the pot.
A scuba diver is 3.8 meters below the surface of the water. He is descending at a rate of 0.5 meters per minute.
Part 1:
Write an algebraic expression to describe the depth of the scuba diver after any number of minutes.
Part 2:
Describe what the variable represents in this situation.
Answer:
[tex]-3.8-0.5x[/tex]
Step-by-step explanation:
A scuba diver is 3.8 meters below the surface of the water.
So, Depth of scuba driver is - 3.8 m
He is descending at a rate of 0.5 meters per minute.
So, Rate = -0.5 m . min
So,Distance traveled in x minutes = -0.05 x
So, The depth after x minutes = -3.8-0.5x
So, an algebraic expression to describe the depth of the scuba diver after any number of minutes is -3.8-0.5x
The variable x represents the no. of minutes .

f(x)=-x^2+8x-20 find the min/max value
The maximum value of the quadratic function f(x)=-[tex]x^2+8x-20[/tex] is -4, which occurs at x=4. This value can be found by using the vertex formula for parabolas.
The function in question is f(x)=-[tex]x^2[/tex]+8x-20. This is a quadratic function, and since the coefficient of [tex]x^2[/tex] is negative, the graph of the function will be a downward-opening parabola. To find the maximum value of this function, we need to determine the vertex of the parabola.
The vertex of a parabola in the form of f(x)=[tex]ax^2[/tex]+bx+c is given by the formula h=-b/(2a). Plugging in our coefficients a=-1 and b=8, we find the x-coordinate of the vertex to be h=-8/(2(-1))=4. To find the corresponding y-coordinate, which is the maximum value, we substitute x=4 into the original function [tex]ax^2[/tex]+bx+c:
f(4)=[tex]-4^2+8\times4-20[/tex]
f(4)=-16+32-20
f(4)=-4
Therefore, the maximum value of the function f(x)=-[tex]x^2+8x-20[/tex] is -4, which occurs at x=4.
