A rectangular park has an area of 64 square yards. If we multiply its length and width by 12, what will be the area of the new rectangle?
Answer:
9216 see explanation
Step-by-step explanation:
area of a rectangle =l×b
let the area and the breadth of the rectangle be x an y respectively
Now
x×y=64cm^2
as we have to multiply the length and breadth both by 12 the new area will be x×y=64×12×12 so the new area would be 9216

First, let us list the factours of 64:
[tex]\displaystyle 1, 2, 4, 8, 16, 32, 64[/tex]
Any two factours of 64 would do [two eights would wourk of cource, but the park is not square-shaped]:
[tex]\displaystyle 9126 = [2(12)][32(12)] \\ 9126 = [4(12)][16(12)][/tex]

Answer:
350Step-by-step explanation:
The completed problem is
[tex]5 \times 70=5\times 7 \ tens.\\5 \times 70=35 \ tens=350[/tex]
Basically, the process is only about separating tens from units, so basically "tens" represents the zero, that's why we only multiply 5 and 7 digits, and add the zero at the end. It's an easier way to multiply tens.
Assume that after t hours on the job, a factory worker can produce 100te^-.5t units per hour. How many units does the worker produce during the first three hours?
Final answer:
To find the number of units that the worker produces during the first three hours, we need to calculate the integral of the production function from 0 to 3. The production function is given as 100te^-0.5t. Using the power rule and the exponential rule of integration, we can find that the worker produces approximately -300e^-1.5 units during the first three hours on the job.
Explanation:
To find the number of units that the worker produces during the first three hours, we need to calculate the integral of the production function from 0 to 3.
The production function is given as 100te^-0.5t.
To integrate this function, we can use the power rule and the exponential rule of integration.
Now, we can plug in the values from 0 to 3 in the integral and calculate the result.
First, plug in the value t=3 in the integral: -100(3)e^-0.5(3) = -300e^-1.5.Then, plug in the value t=0 in the integral: -100(0)e^-0.5(0) = 0.Finally, subtract the result from step 2 from the result from step 1: -300e^-1.5 - 0 = -300e^-1.5.Therefore, the worker produces approximately -300e^-1.5 units during the first three hours on the job.
Blake made and 87 on the first semester of algebra 1 . What score can he make on the second semester if he wants his average to be more than a 90 for both semesters? Answer using complete sentences
In Mathematics, to find the average score which is more than 90 over two semesters when the first semester's score is 87, Blake needs to score more than 93 on his second semester.
Explanation:In Mathematics, specifically algebra, finding an average involves adding up all the values and then dividing by the total number of values. In this case, we're trying to find out the minimum possible score Blake needs in the second semester in order for his total average to be over 90.
Let's denote the score in the second semester as 'x'. Since the average is calculated by (first semester score + second semester score)/2, and since Blake wants his average to be more than 90, we express this as:(87+x)/2 > 90.
We now solve for x: Multiply both sides by 2 to get; 87 + x > 180. Then subtract 87 from both sides to solve for x, which yields; x > 93.
Therefore, Blake needs to score more than 93 in his second semester to have an overall average greater than 90 for both semesters.

Manuel has 13 granola bars to split among 5 people. Express the number of granola bars that each person receives as a quotient and remainder.
In Art class, Mr. Jocelyn gave everyone a1 foot stick to measure and cut. Vivian measured and cut her stick into 5 equal pieces. Scott measured and cut his into 7 equal pieces. Scott said to Vivian, "the total length of my stick is longer than yours because I have 7 pieces, and you only have 5" is that correct?
Scott is incorrect thinking his stick is longer; both received identical 1 foot sticks, so total lengths remain the same despite the number of pieces they are cut into.
The student's question involves Scott believing that because he has more pieces, the total length of his stick is longer than Vivian's. Scott and Vivian both received a 1 foot stick and divided it into equal pieces; Scott into 7 pieces and Vivian into 5.
This problem is related to the concept of division where each person divides their total length equally among the number of pieces, which means the length of each individual piece changes, but the total length of the stick remains the same. Scott is not correct; the total lengths of their sticks are identical, each being 1 foot in length before cutting, regardless of the number of pieces they've been cut into.

1.At a video arcade , Jenny buys 25 tokens.She uses two tokens for each game She plays.
a ) Write an expression for the number of tokens Jenny left after playing g games.
b) Find the number of tokens Jenny has left after playing 1,4,6,10 and 12 games.
Answer:
The required expression is [tex]25-2g[/tex]
She left with 23 tokens after playing 1 game.
She left with 17 tokens after playing 4 game.
She left with 13 tokens after playing 6 game.
She left with 5 tokens after playing 10 game.
She left with 1 tokens after playing 12 game.
Step-by-step explanation:
Consider the provide information.
Part (A)
At a video arcade, Jenny buys 25 tokens. She uses two tokens for each game She plays.
Let the number of games she plays represented by g.
For each game she need to use 2 tokens.
Thus for g games she will use 2g tokens.
Thus, the required expression is: [tex]25-2g[/tex]
Part (B) Find the number of tokens Jenny has left after playing 1,4,6,10 and 12 games.
The number of tokens Jenny has left after playing 1, is:
[tex]25-2(1)[/tex]
[tex]25-2[/tex]
[tex]23[/tex]
Hence, she left with 23 tokens after playing 1 game.
The number of tokens Jenny has left after playing 4, is:
[tex]25-2(4)[/tex]
[tex]25-8[/tex]
[tex]17[/tex]
Hence, she left with 17 tokens after playing 4 game.
The number of tokens Jenny has left after playing 6, is:
[tex]25-2(6)[/tex]
[tex]25-12[/tex]
[tex]13[/tex]
Hence, she left with 13 tokens after playing 6 game.
The number of tokens Jenny has left after playing 10, is:
[tex]25-2(10)[/tex]
[tex]25-20[/tex]
[tex]5[/tex]
Hence, she left with 5 tokens after playing 10 game.
The number of tokens Jenny has left after playing 12, is:

when Raphael solved the system below by using the method of elimination, he changed the second equation to -8x-2y=-2 what property justifies this manipulation?
8x+3y=7
4x+y=1
Raphael used the Property of Equality to justify his manipulation of the second equation.
Explanation:The property that justifies Raphael's manipulation is the Property of Equality. According to this property, if two expressions are equal, then subtracting or adding the same quantity to both sides of the equation will still give you an equal equation. In this case, Raphael changed the second equation to -8x - 2y = -2 by subtracting 1 from both sides of the equation.

Step-by-step explanation:
We have been given that there are [tex](5^3)^2\cdot 5^0[/tex] hens in a bird enclosure. We are asked to find the total number of hens in the enclosure.
Using exponent property [tex]a^0=1[/tex], we will get:

Find k so that 25x^2+40x+k is the square of a binomial
Final answer:
To find k to make a quadratic expression a perfect square of a binomial, we must compare coefficients and solve equations for a and b. Finally, by substituting the values of a and b, the value of k can be determined as 16.
Explanation:
To find k so that 25x^2 + 40x + k is the square of a binomial, we aim to express 25x^2 + 40x + k as the square of the binomial form (ax + b)^2. Comparing coefficients gives us:
2ab = 40 (from the linear term)
a^2 = 25 (from the quadratic term)
Solving these equations, we find a = 5 and b = 4. Therefore, the value of k is 16.
Does 4.5, 6, 7.5 form a right triangle
Final answer:
The numbers 4.5, 6, and 7.5 can form the sides of a right triangle as their squared lengths satisfy the Pythagorean theorem where 4.5² + 6² equals 7.5².
Explanation:
To determine whether the numbers 4.5, 6, 7.5 can form the sides of a right triangle, we can apply the Pythagorean theorem.
This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
According to the given numbers, if we assume that 7.5 is the length of the hypotenuse, then:
4.5² + 6² should equal 7.5²
Calculating each term gives us:
4.5² = 20.256² = 367.5² = 56.25Adding the squares of the possible legs:
20.25 + 36 = 56.25, which is indeed the square of the hypotenuse. This confirms that 4.5, 6, and 7.5 can indeed form a right triangle.
