y = 0.25*85.

What is percentage?

A number or ratio expressed as a fraction of 100 is known as a percentage in mathematics. Though the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent sign, "%," is frequently used to indicate it. An amount that is a percentage is dimensionless and has no assigned measurement.

Given:

The current box holds 85 ounces, 25% less rice.

We have to find the equation which is use to find the original amount of ounces of rice in a box, when the current box holds 85 ounces, 25% less rice.

Let, y be the original amount of ounces of rice in a box.

The current box holds 85 ounces.

The 25% less than 85 ounces are 85*0.25.

So, the equation becomes y = 0.25*85.

Hence, the equation which is use to find the original amount of ounces of rice in a box, when the current box holds 85 ounces, 25% less rice is  

y = 0.25*85.

Andrew would need to invest $61,300 for the account to reach $93,000.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

The equation to find final amount in compound interest is,

A = P (1 + r/n)^(n t)

Here A is the final amount, P is the initial amount, r is the rate of interest, n is the number of times compounding is done in a year, t is the time in years.

Given, A = $93,000

t = 19 years

r = 2.2% = 0.022

n = 4 (since compounding is quarterly)

93,000 = P [1 + (0.022/4)]^(4×19)

93,000 = P [1.0055]^(76)

93,000 = P (1.517)

P = 61,297.8516

To the nearest hundred dollars, P = $61,300

Hence the principal amount Andrew need to invest is $61,300.

The term equation is known as a mathematical statement that shows that two mathematical expressions are equal.

Here we have given that the first plant produces 5x+14 items daily

And the second plant produces 3x-7 items daily

In order to find the number of items produced on first plant, then we have to calculate the differences between number of items by the two plants daily, then it can be written as by using the equations,

=> (5x+14) - (3x-7)

Now, we have to expand the equations, then we get

=> 5x+14 - 3x+7

=> 2x+21

Answer: 5x − 4 > 2x + 3

Step-by-step explanation:

The expression 5x − 4 > 2x + 3 looks like an equation but with the equals sign replaced by an arrowhead. It is an example of an inequality. This denotes that the part on the left, 5x − 4, is greater than the part on the right, 2x + 3.

0 to the 0 exponents is undefined or indeterminate, and it's not considered as a valid mathematical operation.

The value of 0 to the 0 exponents is undefined or indeterminate. The reason for this is that the mathematical definition of exponentiation states that any number to the power of 0 is equal to 1, except for 0, which is undefined. However, when we try to apply this rule to 0 to the power of 0, it creates a paradox.

If we assume that 0 to the 0 exponents is 1, then any number raised to the power of 0 would be equal to 1, which is not true. For example, 2 to the power of 0 is not equal to 1, but 2, so this assumption doesn't hold true.

On the other hand, if we assume that 0 to the 0 exponents is 0, then any number multiplied by 0 would be 0, which is not true either. For example, 2 multiplied by 0 is not equal to 2.

Therefore, 0 to the 0 exponents is undefined or indeterminate, and it's not considered as a valid mathematical operation.

It's important to note that in some fields of mathematics such as limit, the value of 0 to the 0 exponent is defined as 1, but this is limited to the context of limit and not in general math.

Step-by-step explanation:

Sara will win a medal if she keeps practicing gymnastics.

The reflection of (-3, 2) over the y-axis is (-3, -2).

The reflection of a point (x, y) over the y-axis is (x, -y).

Therefore, the reflection of (-3, 2) over the y-axis is (-3, -2).

To calculate the reflection of (-3, 2) over the y-axis, we first use the formula (x, -y).

In this case, x = -3 and y = 2, so the reflection of (-3, 2) over the y-axis is (-3, -2).

We can also calculate the reflection of (-3, 2) over the y-axis using the distance formula.

The distance formula  is d = √(x2-x1)2 + (y2-y1)2

In this case, x1 = -3, x2 = 0, y1 = 2, and y2 = 0.

Therefore, the distance d = √(02-(-3)2 + (02-2)2 = √(9 + 4) = √13

The reflection of (-3, 2) over the y-axis is (-3, -2). This can be verified using the distance formula.

d = √(x2-x1)2 + (y2-y1)2 = √(-3-0)2 + (-2-0)2 = √(9+4) = √13

The distance d is equal to the distance between (-3, 2) and (-3, -2). Hence, the reflection of (-3, 2) over the y-axis is (-3, -2).

The box has 18 glazed donut hole that Chad bought.

The percentage of glazed donut holes = 60%

The percentage of powdered sugar donut hole = (100 - 60) % = 40%

Let us consider the total number of donut hole in the box bought by Chad to be 'x'

Number of powdered sugar donut hole = 12

Hence, we can say that the number of powdered sugar donut hole in the box Chad bought is:

(40% of x) = 12

Therefore, x = (12 x 100) / 40 = 30

Since the total number of donut hole in the box = 30

The number of glazed donut hole = 30 - 12 = 18

Thus, the box that Chad bought had 18 glazed donut hole.

To solve the equation (3.4)(6.7) using the standard algorithm, first multiply 3.4 and 6.7. Then, the result is 22.78.

The standard algorithm for multiplication is a step-by-step process that involves breaking down the numbers being multiplied into simpler parts, and then multiplying those parts together.

First, you would need to multiply the ones place of the first number (4) by the ones place of the second number (7), which would give you 28.

Next, you would need to multiply the ones place of the first number (4) by the tens place of the second number (6), which would give you 24.

Then, you would add the two products from steps 1 and 2 to get the result: 28 + 24 = 52.

Alternatively, you can use the distributive property of multiplication to simplify the problem.

(3.4)(6.7) = 3.46 + 3.40.7 = 22.8
