2 1/9 of what number is 76?
The value of the unknown number is 36. 2 1/9 of 36 is 76.
The is the value of the missing number?Given the parameter:
2 1/9 of what number is 76?
To solve for the unknown value, first, convert the mixed fraction to an improper fraction:
2 1/9 = ( 9×2 + 1 )/9 = 19/9
Now, we set up the equation:
Let 'x' represent the unknown number:
19/9 of x is 76
19/9 × x = 76
Solve for x:
19x/9 = 76
19x = 9 × 76
19x = 684
x = 684/19
x = 36
Therefore, the value of x is 36.

The expression 0.09x+(x−30) models the final price of a bicycle with an instant rebate in a state that charges a sales tax. The tax is on the original price. Which expression represents the amount of tax that is paid on the bicycle?
A) 1.09x
B) 0.09x
C) 0.09x - 30
D) x - 30
The correct answer is option B). The expression that represents the amount of tax paid on the bicycle is 0.09x.
The expression given is:
[tex]\[ 0.09x + (x - 30) \][/tex]
This expression can be broken down into two parts:
1. [tex]\( 0.09x \)[/tex] represents the tax paid on the original price of the bicycle, where [tex]\( x \)[/tex] is the original price and [tex]\( 0.09 \)[/tex] (or [tex]\( 9\% \)[/tex]) is the tax rate.
2. [tex]\( (x - 30) \)[/tex] represents the final price after the instant rebate of $30 has been subtracted from the original price [tex]\( x \)[/tex].
Since we are looking for the amount of tax paid, we only need to consider the tax component, which is [tex]\( 0.09x \)[/tex].
Therefore, the expression that represents the amount of tax paid on the bicycle is: [tex]{0.09x}[/tex]

Olivia ate four times as much salad as Reagan. If Reagan ate r salad, which equation can be used to find the amount of salad Olivia ate, v?
A. 4r = v
B. r + 4 =
C.v + 4 = r
D. 4v = r
Answer:
A. 4r = v
Step-by-step explanation:
the amount of salad Reagan ate is r.
If Olivia ate 4 times as much salad as Reagan, then she ate r amount multiplied by 4:
4r
Thus, the equation than can be used to describe the amount of salad for Olivia is:
4r = v
This is because this equation tells us that 4 times the amount of salad Reagan ate (4r) is equal to what Olivia ate (v)

Four balls of wool will make 8 knitted caps. How many balls of wool will Malcom need if he wants to make 6 caps. Explain with Ratio table.
8/4 = 2 caps per ball of wool
so 6/2 = 3 balls of wool are needed.
4/8 = x/6
8x/24
x = 24/8 = 3
Malcom will need 3 balls of wool to make 6 caps.
Understanding Wool to Caps Ratio
To determine how many balls of wool Malcom will need to make 6 caps, we will use a ratio table. We know that 4 balls of wool can make 8 knitted caps. We can set up a ratio table to find the number of balls needed for any number of caps.
Step-by-Step Explanation:
Step 1: Establish the known ratio: 4 balls of wool : 8 caps
Step 2: Simplify the ratio: (4 balls of wool) / (8 caps) = 1 ball of wool : 2 caps
Step 3: Determine the number of balls of wool needed for 6 caps using the simplified ratio. If 1 ball of wool makes 2 caps, then:
Step 4: Calculate: (number of caps) / (caps per ball) = 6 caps / 2 caps per ball = 3 balls of wool
Therefore, Malcom will need 3 balls of wool to make 6 caps.

The Pythagorean Sea, in Southern Antarctica has a depth that varies quadratically with its width. The width of the sea is 1000 meters. Two hundred meters from shore, the depth is 20 meters. Find the particular quadratic equation for the sea. Compute the depth of the deepest portion of the sea.
Final answer:
To find the quadratic equation that models the depth of the Pythagorean Sea, we apply given conditions to the standard form y = ax^2 + bx + c. Solving for coefficients, we then identify the vertex of the parabola to find the deepest point of the sea. Finally, we calculate the depth at this point by substituting the vertex into the equation.
Explanation:
Finding the Particular Quadratic Equation and Depth of the Sea
To find the particular quadratic equation for the depth of the Pythagorean Sea as a function of its width, we can begin by assuming the standard form of the equation:
y = ax^2 + bx + c,
where y represents the depth in meters, and x is the horizontal distance from the shore in meters. Given that the sea's width is 1000 meters and at 200 meters from the shore the depth is 20 meters, we can establish some conditions.
At x = 0 (shoreline), the depth is 0: hence, c = 0.At x = 200 meters, the depth is y = 20 meters.At x = 1000 meters (opposite shoreline), the depth should return to 0.By substituting these conditions into the equation, we can solve for a and b to determine the complete equation. Once we have the equation, the depth's maximum (the deepest part of the sea) will occur at the vertex of the parabola, which is at x = -b/(2a).
Once we find the deepest point, we can calculate its depth by substituting back into the equation.
Answer:
equation: y = 0.0005x²
maximum depth: 500 m
Step-by-step explanation:
Equation for a quantity that changes quadratically with another quantity:
y = kx²
where x = width, and y = depth.
For x = 200, y = 20.
20 = k(200²)
k = 20/(40000)
k = 0.0005
The equation is
y = 0.0005x²
The width is 1000 m.
For 1000 m, x = 1000
y = 0.0005x²
y = 0.0005(1000²)
y = 500
Answer:
equation: y = 0.0005x²
maximum depth: 500 m

Is 13-yard gain a positive or negitave integer?Explain the meaning of zero in this situation.
Answer:
Positive integer
Step-by-step explanation:
An integer is a collection of positive and negative number and zero
Positive Numbers: Positive number are the numbers which have positive sign. For example 4, 9 or which which represents positivity like gain , increase, profit etc
Negative numbers: Negative number are the numbers which have negative sign. For example -4, -9 or which which represents negativity like loss , decrease etc
Zero is neither a negative number nor a positive number.
13 yard is a positive because there is a gain , which represent positivity.
We can also write + 13 yard.
Hence, the correct answer is it is a positive integer
