Answer: 681 square inch
Step-by-step explanation:
Hi, we have to apply the formula for the surface area:
A = 2wl + 2lh + 2hw
Where:
w: width
l: length
h: height
Replacing with the values given:
A = (2x12x18.25) + (2x12x3)+(2x18.25x3)
A= 438+72+109.25
A=619.5 in2
Since it has to be 10% more than the surface.
619.5 x (10/100) = 61.95 in2
Adding that value to the surface area
619.5+61.95 = 681.45in2 = 681 in2
The advertised price of a cell phone was $99.99 after a $50 mail-in rebate. What is the price of the cell phone before the rebate is applied?
Answer:
149.99
Step-by-step explanation:add 50
Answer:
$149.99
Step-by-step explanation:
The price of the phone is $99.99 after the rebate, so we have to add the rebate back on to find the original price.
99.99+50
149.99
Someone gave me a riddle to solve if anyone wants to help me out for 25 points i’d appreciate it:)
It appears the first two digits in the code is the two digits out front multiplied together. The next digit or two are the sum of the two numbers. The last number or two is the difference.
7x3 = 21
7+3 = 10
7-3 = 4
(7)(3) = 21104
It's the same process for the (9)(4) = 36135
So for (8)(5) would be:
8x5=40
8+5=13
8-5=3
(8)(5)= 40133
Answer:
40133
Step-by-step explanation:
Basically,
The first 2 digits you multiply 8 and 5. Which is 40. Then you add 8 and 5 which is 13. Then subtract 8 and 5 which is 3.
So putting them together you get 40133

Stay Safe! Stay at Home!! =)
The slope between the points (8,-4) and (2,-4) is 0, indicating a horizontal line.
Explanation:To find the slope between two points, you use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
Let's apply this formula to the points given: (8, -4) and (2, -4).
Slope (m) = (-4 - (-4)) / (2 - 8) = (0) / (-6) = 0
Since the numerator of the slope formula is zero, the slope of the line passing through these two points is 0, which indicates a horizontal line.

Answer:
B
Step-by-step explanation:
The slope would be the same becasue the lines are parellel.

What is 2(log38+logzz)-log3(34 – 72) written as a single logarithm?
To simplify the given expression, we can use the properties of logarithms. By using the product, power, and quotient rules of logarithms, we can combine the terms and simplify the expression into a single logarithm.
Explanation:To simplify the given expression 2(log(38) + log(zz)) - log3(34 - 72), we can use the properties of logarithms.
Start by using the product rule of logarithms to combine the terms inside the parentheses: log(38zz).Now, use the power rule of logarithms to bring the exponent out as a coefficient: log(38) + log(zz).Next, apply the quotient rule of logarithms to subtract the logarithm of the denominator: log(38) + log(zz) - log3(-38).Finally, simplify the expression: log(38zz/(-38)).This is the single logarithm form of the given expression.

Marty was paying off a television that he bought on layaway, which means he has to pay it off over a period of time. Marty made 3 upfront payments over three weeks. One week he paid $20, next week $30, and the next week $40( remember he paid some money already). The total cost of the tv was $690. He will now make monthly payments to pay off the rest that he owes. If he has another 12 months to pay it off, how much will he have to pay per month?

2(5 - x)>8 solve for x
Answer:
x < 1
Step-by-step explanation:
To solve for x, we need to get x by itself
2(5 - x)>8
Distribute the 2
2*5 -2*x >8
10- 2x >8
Subtract 10 from both sides
10-10 -2x >8 -10
-2x > -2
Divide both sides by -2
-2x/-2> -2/-2
Since we divided by a negative number, we must flip the inequality sign
x < 1
Answer:
x < 1
Step-by-step explanation:
Given
2(5 - x) > 8 ( divide both sides by 2 )
5 - x > 4 ( subtract 5 from both sides )
- x > - 1
Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.

A target with a diameter of 42 cm has 4 scoring zones formed by concentric circles. The diameter of the center circle is 6 cm. The width of each ring is 6 cm. A dart hits the target at a
random point. Find the probability that it will hit a point in the yellow region
The probability of a dart hitting the yellow region of the target can be calculated by determining the area of the yellow region, in this case about 1130.97 cm^2, and dividing it by the total area of the target, which is about 1385.44 cm^2. The resulting probability is approximately 0.82, or 82%.
Explanation:To solve this, we must first understand that the probability of the dart hitting a certain zone on the target will be proportional to the area of that zone. In this case, the entire area of the target is the area of the circle with a diameter of 42 cm. The radius of the target, therefore, is 21 cm.
The formula for the area of a circle is πr^2, so the area of the target is π * (21)^2, or about 1385.44 cm^2.
While the yellow zone is the ring with 18 cm diameter. Using the formula for the area of a circle again, the inner boundary of the yellow zone will have an area of π * (9)^2, or about 254.47 cm^2. The area of the yellow zone is the difference between these two values, which is around 1130.97 cm^2.
To find the probability of a dart hitting the yellow zone, we divide the area of the yellow zone by the total area of the target. This gives us a probability of around 0.82, or 82%.

XYZ and WYZ are non overlapping angles that share a ray and form XYZ. WYZ has a measure of 32"". XYW has a measure of 112*. What is the measure of XYZ?
Answer: XYZ = 144 degree
Step-by-step explanation:
The non overlapping angles are said to be adjacent angles of a common vertex and a common side but do not overlap.
If WYZ has a measure of 32 degree.
And XYW has a measure of 112 degree
Then, the measure of XYZ will be
XYZ = WYZ + XYW
XYZ = 32 + 112
XYZ = 144 degree
find the radius of the sphere with a volume of 32/81 π cubic yards. Write your answer as a fraction in simplest form.
Answer:
Step-by-step explanation:
The radius of the sphere with a volume of 32/81 π cubic yards is 2/3 yards. This is found by equating the given volume to the volume of a sphere formula and solving for the radius step-by-step.
To find the radius of a sphere given its volume, we can use the formula for the volume of a sphere, which is V = (4/3)πr³. In this case, we have the volume V= 32/81 π cubic yards. We need to solve for r (the radius).
First, we set the given volume equal to the volume formula:
32/81 π = (4/3)πr³
To solve for r³, we divide both sides by (4/3)π:
r³ = (32/81 π) / ((4/3)π) = (32/81) / (4/3) = 32/81 * 3/4 = 32/108 = 8/27
Now, to find r, we take the cube root of both sides:
r = ³√(8/27)
Since ³√8 = 2 and ³√27 = 3, the radius r is 2/3 yards.

X and y vary inversely. If x is 3 when y is 12, find the equation to model this situation
Answer:
[tex]x = \dfrac{36}{y}[/tex]
Step-by-step explanation:
We are given the following in the question:
x and y vary inversely.
[tex]x\propto \dfrac{1}{y}[/tex]
Removing the sign of proportionality and adding the constant of proportionality, we get,
[tex]x = k\times \dfrac{1}{y} = \dfrac{k}{y}[/tex]
where k is the constant of proportionality.
When x = 3, y = 12
Putting these value in the equation, we get,
[tex]3 = \dfrac{k}{12}\\\\\Rightarrow k = 12\times 3 = 36[/tex]
Putting value of k, we get,
[tex]x = \dfrac{36}{y}[/tex]
which is the required equation to model the given situation.

For this just identify. M=slope. The number next to the x is 2. So the answer is 2
Answer:
Slope is 2: y = 2x + 1/2
Step-by-step explanation:
2y - 4x = 1
+ 4x + 4x (Add 4x to both sides to leave y by itself on one side)
------
2y/2 = 4x/2 + 1/2 (Divide both sides by 2 in order to leave y with no coefficient)
y = 2x + 1/2
