Can you make a math equation turn from + to x with the same numbers and get the same answer but the numbers dont have to be in the same order
Answer:
See explanations below
Step-by-step explanation:
Let the numbers be 2 and 2
Taking the sum using the plus(+) sign
2 + 2 = 4
Taking the product using the multiplication sign (×)
2×2 = 4
You can see that the answer to both expression are equal even by changing the sign from + to × that is;
2+2 = 2×2 = 4
The sum of two numbers is 60 and the difference is 4. What are the numbers?
Answer: One number is 32, the other is 28
Step-by-step explanation:
Let's solve this problem with a system of equations
Let the x be one number, y be the other number
--------------------------------------------------------------------------------------
x+y=60
x-y=4
2x=64
x=32
---------------------------------------------------------------------------------
Substitute x value into one of the equations
x-y=4
32-y=4
y=28
Hope this helps!! :)

Stan has a rectangular piece of carpet with an area of 23.4 square meters. The piece of carpet is 13 meters long. What is the width of the piece of carpet?
Answer:
The breadth of rectangular carpet is 1.8 m.
Step-by-step explanation:
We have,
The area of rectangular carpet that is 23.4 m²The length of carpet is 13 m.We know that,
= Area of rectangle = Length × Breadth
= 23.4 = 13 × Breadth
= 23.4/13 = Breadth
= 234/130 = Breadth
= 1.8 m = Breadth

PLEASE HELP I AM SO STUCK. IT IS DUE ~TOMORROW.
Answer:
[tex] A(\triangle ABC) = 7.2\: units^2 [/tex]
Step-by-step explanation:
C = (0, 7)
Since, point A lies on y-axis, so it's x coordinate will be zero. Line y = 2x + 1 passes through point A.
Therefore, plug x = 0 in y = 2x +1, we find:
y = 2*0 + 1 = 0 + 1 = 1
Hence, coordinates of point A are (0, 1).
Now, by distance formula:
[tex] AC= \sqrt{(0-0)^2 +(7-1)^2} [/tex]
[tex] AC= \sqrt{(0)^2 +(6)^2 }[/tex]
[tex] AC= \sqrt{0 +36 }[/tex]
[tex] AC= \sqrt{36 }[/tex]
[tex] AC= 6\: units[/tex]
Length of perpendicular CB dropped from point C (0, 7) to line y = 2x + 1 or 2x - y + 1 = 0 can be obtained as given below:
[tex] CB =\frac{|2\times 0+(-1)\times 7+1|}{\sqrt {2^2 +(-1)^2} } [/tex]
[tex] CB =\frac{|0-7+1|}{\sqrt {4 +1} } [/tex]
[tex] CB =\frac{|-6|}{\sqrt {5} } [/tex]
[tex] CB =\frac{6}{2.24} [/tex]
[tex] CB =2.68\: units [/tex]
By Pythagoras Theorem:
[tex] AB=\sqrt{AC^2 - CB^2} [/tex]
[tex] AB=\sqrt{6^2 - (2.68)^2} [/tex]
[tex] AB=\sqrt{36 - 7.18} [/tex]
[tex] AB=\sqrt{28.82} [/tex]
[tex] AB=5.36842621\: units [/tex]
[tex] AB\approx 5.37\: units [/tex]
[tex] A(\triangle ABC) = \frac{1}{2} \times AB\times CB[/tex]
[tex] A(\triangle ABC) = \frac{1}{2} \times 5.37\times 2.68[/tex]
[tex] A(\triangle ABC) = \frac{1}{2} \times 14.3916[/tex]
[tex] A(\triangle ABC) = 7.1958[/tex]

this is area of shaded region and i really need your help pls...
Answer:
4925cm^2
Step-by-step explanation:
whole thing - small thing = shaded
small = 25 x 25 = 625
whole thing = a+b / 2 x h = 111+111/2 x 50 = 5550
5550-625= 4925cm^2
If the area of a sector is 100 ft^2 and the radius of the circle is 22 ft what is the central angle measure for that sector and what is the length of the arc
Answer:
[tex]\displaystyle \theta=0.413\ rad[/tex]
L= 9.086 feet
Step-by-step explanation:
Area of a Circular Sector
Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by
[tex]\displaystyle A=\frac{1}{2}r^2\theta[/tex]
And the length of the arc is:
[tex]L=\theta r[/tex]
We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:
[tex]\displaystyle 100=\frac{1}{2}r^2\theta[/tex]
Solving for θ:
[tex]\displaystyle \theta=\frac{200}{r^2}[/tex]
[tex]\displaystyle \theta=\frac{200}{22^2}[/tex]
[tex]\displaystyle \theta=0.413\ rad[/tex]
The arc length is:
[tex]L=0.413* 22[/tex]
L= 9.086 feet
The average of a list of 4 numbers is 90.0 . A new list of 4 numbers has the same first 3 numbers as the original list, but the fourth number in the original list is 80 , and the fourth number in the new list is 96 . What is the average of this new list of numbers?
Answer:
94
Step-by-step explanation:
Average = sum of numbers / number of items in the set
for the first list, the average is 90 and there are four numbers, the sum of the numbers is 90 x 4 = 360
If the 4th number is 80, the sum of the first 3 numbers = 360 - 80 = 280
so the sum of the first three numbers on the second list is 260. The fourth number is 96. The sum of the numbers = 280 + 96 = 376
Average of the new list = 376 / 4 = 94

At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41. The rate the Starbucks stock value was changing is - per hour
Answer:
1.50$
Step-by-step explanation:
difference in money amount: $6
difference in hours: 4
6 divided by 4 equals 1.50.
1.50 times 4 equals 6, hence its 1.50 per hour.
The rate of change in the Starbucks stock value is 150%.
Given that, At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41.
We need to find the rate the Starbucks stock value was changing is - per hour.
What is the rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now, the difference in money=41-35=$6
The number of hours between 10 AM to 2 PM is 4 hours.
The rate of change = The difference in money/Number of hours × 100
=6/4 × 100
=150%
Therefore, the rate of change in the Starbucks stock value is 150%.
