The perimetre of a rectangle is 38cm length is 12.5, What is the Area?..
Answer:
[tex]\boxed{\mathtt{Area = 81.25cm^{2}}}[/tex]
Step-by-step explanation:
[tex]\textsf{For this problem, we are asked to solve for the \underline{Area} of a Rectangle.}[/tex]
[tex]\textsf{We are given the \underline{Perimeter}, and the \underline{Length}.}[/tex]
[tex]\textsf{We should begin by identifying the formulas for Perimeter and Area.}[/tex]
[tex]\mathtt{Perimeter = Length + Length + WIdth + Width}[/tex]
[tex]\mathtt{Area = Length \times Width}[/tex]
[tex]\textsf{Because we're given the Perimeter and the Length, we can identify the Width.}[/tex]
[tex]\large\underline{\textsf{Substitute:}}[/tex]
[tex]\mathtt{38 cm = 12.5 + 12.5 + Width + Width}[/tex]
[tex]\large\underline{\textsf{Combine Like Terms:}}[/tex]
[tex]\mathtt{38 cm = 25 cm+ 2(Width)}[/tex]
[tex]\large\underline{\textsf{Subtract 25 from both sides:}}[/tex]
[tex]\mathtt{13 cm = 2(Width)}[/tex]
[tex]\large\underline{\textsf{Divide By 2:}}[/tex]
[tex]\mathtt{6.5 cm = Width}[/tex]
[tex]\textsf{Now that we know the Width, we can identify the Area.}[/tex]
[tex]\large\underline{\textsf{Substitute:}}[/tex]
[tex]\mathtt{Area = 12.5 cm \times 6.5cm}[/tex]
[tex]\boxed{\mathtt{Area = 81.25cm^{2}}}[/tex]

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs.
q and t are alternate interior
r and k are alternate interior
W is 79
The mistake he made is equating an alternate interior angle to an alternate exterior angle
1 .When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.
Alternate exterior angles are those angles that have different vertices, lie on the alternate sides of the transversal, and are exterior to the lines. When a transversal intersects two parallel lines, the alternate exterior angles formed are always equal.
2. check the picture for translation of the angles
3. 8 angles are created, 4 alternate interior and 4 alternate exterior
Angles 6,4 and 2 are congruent to 8
In question 8, the equation above must be equal to the written degree below. Your image isnt so clear

Jeff had $20. He spent 3/8 of his money on lunch. How much money does Jeff have left?
A. $12.50
B. $7.50
C. $8.25
D. $16.75
Answer: Option A, $12.50
Step-by-step explanation: Jeff spent 3/8 of his money, which can be represented by the equation as follows:
1 - 3/8 = 5/8
where 1 represents 8/8, or $20, and 5/8 represents the remainder of Jeff's money.
To find how much money Jeff has left, we can multiply his initial investment by 5/8:
$20 × 5/8 = $100/8, or $12.50
Hence, Jeff has $12.50 leftover, which is represented by option A.

The singh family orderd a large pizza with a diameter of 20 inches for dinner. If one of the members ate one-eighth of the pizza, how many square inches of pizza are remaining? (use 3.14 for pi)
Answer:
275.5 square inches of pizza remaining
Step-by-step explanation:
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.
The diameter of the pizza is 20 inches, so the radius is half of that, or 10 inches.
The area of the entire pizza is:
A = πr^2 = 3.14 x 10^2 = 314 square inches.
If one member of the family ate one eighth of the pizza, then the amount of pizza remaining is 7/8 of the original amount.
The remaining area of the pizza is:
(7/8) x 314 = 275.5 square inches.
Therefore, there are 275.5 square inches of pizza remaining.

How much alcohol must a pharmacist add to 10 cm^3 of an 8% alcohol solution to strengthen it to an 80% solution? PLS ANSWER URGENT THANKS
The pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.
What is alcohol ?Alcohol, also known as ethanol is a clear, colorless liquid that is produced by the fermentation of sugars and carbohydrates by yeasts.
Let's start by writing down the equation that relates the amount of alcohol in the original 8% solution to the amount of alcohol in the final 80% solution:
[tex]0.08 x 10 cm^3[/tex] [tex]+ x = 0.80 x (10 cm^3 + x)[/tex]
Here, x represents the amount of pure alcohol that we need to add to the [tex]10 cm^3[/tex] of 8% solution to obtain the desired 80% solution.
The left-hand side of the equation represents the amount of alcohol in the original solution (which is 8% alcohol), while the right-hand side represents the amount of alcohol in the final solution (which is 80% alcohol).
Now we can solve for x:
[tex]0.08 x 10 cm^3 + x = 0.80 x (10 cm^3 + x)[/tex]
[tex]0.8 cm^3 + x = 8 cm^3 + 0.8x[/tex]
[tex]0.2x = 7.2 cm^3[/tex]
[tex]x = 36 cm^3[/tex]
Therefore, the pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

Gianna and her family went for a drive. They traveled 175 miles in 3 hours. What was their average speed?
Would you write an inequality or an equation?
To find the average speed, we divide the total distance traveled by the time taken:
Average speed = Total distance ÷ Time taken
Therefore, Gianna and her family's average speed is:
Average speed = 175 miles ÷ 3 hours = 58.33 miles per hour (rounded to two decimal places)
We use an equation to solve this problem.
Equation: Average speed = Total distance ÷ Time taken
Where:
Total distance = 175 miles
Time taken = 3 hours
Substituting these values into the equation, we get:
Average speed = 175 miles ÷ 3 hours
Therefore, the answer is an equation:
Average speed = 175 miles ÷ 3 hours
The box plots below show the average daily temperatures in April and October for a U.S. city:
What can you tell about the means for these two months?
The mean for April is higher than October's mean.
There is no way of telling what the means are.
The low median for October pulls its mean below April's mean.
The high range for October pulls its mean above April's mean.
Answer:
A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers. For example, with the data set: 8, 9, 5, 6, 7, the mean is 7, as 8 + 9 + 5 + 6 + 7 = 35, 35/5 = 7. So, assuming that's the type of "Mean" your talking about, there is no way of telling what the means are seeing as the picture only shows the averages.

Step-by-step explanation: In order to find the surface area of the tetrahedron in this case you need to know the side length which is already provided. The equation [tex]\sqrt{3} (side^{2} )[/tex] is the square root of 3 multiplied by the square of the side (2) which gets you roughly ≈6.9282 square yards.

Add the algebraic expressions.
a. -6p²+8q² - 2pq- 5 and 2p² -3q² -2pq+3
b. 5x+6y and -8x -3y
Grade8
Answer:
a: -4p² + 5q² - 4pq - 2
b: -3x + 3y
Step-by-step explanation:
When we combine like terms, we get:
(-6p²+8q² - 2pq- 5) + ( 2p² -3q² -2pq+3) = -4p² + 5q² - 4pq - 2
Therefore, the simplified expression is -4p² + 5q² - 4pq - 2.
Next:
(5x+6y)+ (-8x -3y) = 5x - 8x + 6y - 3y
Combining like terms gives us:
5x - 8x + 6y - 3y = -3x + 3y
Therefore, the simplified expression is -3x + 3y.
