Answer:
58 ounces
Step-by-step explanation:
16 x 4=64 - 6=58 ounces
Final answer:
After converting the weight of the cleats from ounces to pounds, the new weight of Bill's baseball bag is determined to be 3.625 pounds by subtracting 0.375 pounds (weight of the cleats in pounds) from the original 4 pounds.
Explanation:
The subject of this question is Mathematics, specifically dealing with unit conversion and simple subtraction of weights. To determine the new weight of Bill's baseball bag after removing the cleats that weigh 6 ounces, we need to first convert the ounces to pounds, since the weight of the bag is given in pounds.
There are 16 ounces in one pound. Therefore, 6 ounces is equivalent to 6 ounces \/ 16 ounces per pound = 0.375 pounds. Starting with the original weight of the bag which is 4 pounds, subtracting the weight of the cleats in pounds will give us the new weight of the bag.
4 pounds - 0.375 pounds = 3.625 pounds. This is the weight of Bill's baseball bag after the cleats are removed.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule
A(n) = 5+(n-1) (1/6)
Answer:
First term: 5
Fourth term: 5 1/2
Tenth term: 6 1/2
Step-by-step explanation:
Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:
A(n) = 5 + (n-1) (1/6)
First term:
A(1) = 5 + (1-1) (1/6)
A(1) = 5 + (0) (1/6)
A(1) = 5
Fourth term:
A(4) = 5 + (4-1) (1/6)
A(4) = 5 + (3) (1/6)
A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)
Tenth term:
A(10) = 5 + (10-1) (1/6)
A(10) = 5 + (9) (1/6)
A (10) = 5 + 9/6 = 6 3/6 = 6 1/2 (simplifying)
4x-y=1 slope intercept form
Answer:
y=4x-1
Step-by-step explanation:
4x-y=1
4x=y+1 then negative Y becomes positive after going to the other side of the equal sign.
4x-1=y the positive 1 becomes negative after going to the other side of the equal sign.
Answer:
y = 4x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x - y = 1 ( subtract 4x from both sides )
- y = - 4x + 1 ( multiply through by - 1 )
y = 4x - 1 ← in slope- intercept form

Which of the following is equivalent to (7x + 3y)(8x + 5y)?
To find the product of (7x + 3y)(8x + 5y), you can use the distributive property of multiplication. The equivalent expression is 56x^2 + 59xy + 15y^2.
Explanation:To find the product of (7x + 3y)(8x + 5y), you can use the distributive property of multiplication over addition.
This means that each term in the first expression is multiplied by each term in the second expression.
Here are the steps:
Apply the distributive property to multiply 7x by each term in the second expression: 7x * 8x + 7x * 5y
Apply the distributive property to multiply 3y by each term in the second expression: 3y * 8x + 3y * 5y
Simplify each term: 56x^2 + 35xy + 24xy + 15y^2
Combine like terms: 56x^2 + 59xy + 15y^2
Therefore, the expression (7x + 3y)(8x + 5y) is equivalent to 56x^2 + 59xy + 15y^2.

D={[x, f(x)]: (-1,3), (0, 2), (1, 3), (2, 6), (3, 11)]
Write the rule for f(x).
Answer:
f(x) = x² +2
Step-by-step explanation:
x-values are evenly spaced, and y-values decrease to a minimum of 2, then increase again. First differences are -1, 1, 3, 5, and second differences are constant at 2. This means that a 2nd degree polynomial can be used for the rule.
The minimum of f(x) occurs at x=0, so there is no horizontal shift of the vertex of the quadratic function. f(1) -f(0) = 1, so the vertical scale factor for the quadratic is 1.
The quadratic with a vertex of (0, 2) and a vertical scale factor of 1 is ...
f(x) = 1·(x -0)² +2
f(x) = x² +2 . . . . . . simplified

Comment on differences
"First differences" are the differences between successive "y" values when the "x" values are evenly spaced. Here, they are 2-3 = -1, 3-2 = 1, 6-3 = 3, 11-6 = 5. These are not constant, so the function is not a linear function.
"Second differences" are the differences between successive first differences. Here, they are 1-(-1) = 2, 3-1 = 2, 5-3 = 2. These are constant, so the function is a quadratic (2nd-degree). When n-th differences are constant, the sequence can be modeled by a polynomial of degree n.
__
Comment on determining the rule
Once you know the rule is 2nd-degree, there are a number of ways you can find out what it is. One way is to write it as ...
f(x) = ax^2 + bx + c
and fill in three different values for x and f(x). This will give you three linear equations in a, b, and c, which can be solved by any of the usual means for solving systems of linear equations.
Fortunately, this set of data includes the vertex of the function, making it easy to start with the vertex form:
f(x) = a(x -h)^2 +k
where (h, k) is the vertex (minimum, in this case), and "a" is the vertical scale factor. The value of "a" is easily determined as being the difference between f(h+1) and f(h). Here, h=0, so that is f(1) -f(0) = 3-2 = 1.

Step-by-step explanation:
Let x = number of people when she got on.
x -4+3 -5+1 -1 = 4
x -6 = 4
Solve for x to get x=10.

1a.) Write an expression that represents the area of a circle with a radius of 7 units? (1 point)
b. Using your expression, solve for the area of a circle with a radius of 7 units. (1 point) PLEASE HELP PLEASE WILL MARK BRAINLIEST AND GIVE POINTS
Final answer:
To find the area of a circle with a radius of 7 units, use the formula A = πr². Substitute 7 for r to get A = π(7²), which calculates to approximately 153.93804 square units. We round it to 150 square units, to match the significant figures of the radius.
Explanation:
The expression representing the area of a circle with a radius of 7 units is A = πr², where 'A' is the area and 'r' is the radius of the circle. To solve for the area with a radius of 7 units:
Substitute the radius (7 units) into the expression: A = π(7²).
Square the radius: 7² = 49.
Multiply by π (approximately 3.14159): A = π(49) or A ≈ 3.14159 × 49.
Calculate the area, which gives approximately 153.93804 square units.
Since the radius is given in two significant figures, you should express the area in two significant figures: A ≈ 150 square units.
15. The volume of a refrigerator is x3-3x2-16x-12. Its height is x + 2. What
are the other two dimensions?
A. x + 6 and x - 1
B. x-3 and x + 2
C. x-2 and x + 3
D. x-6 and x + 1
Final answer:
The volume of the refrigerator is factored by dividing with the given height, resulting in a quadratic polynomial that provides the other two dimensions. Upon factoring, we discover that the other dimensions are x - 6 and x + 1, corresponding to option D.
Explanation:
The volume of the refrigerator is given by the polynomial [tex]x^3 - 3x^2 - 16x - 12[/tex]. To find the other two dimensions of the refrigerator, we need to factor this polynomial using the given height of the refrigerator, which is x + 2. The goal is to divide the volume polynomial by the height polynomial to get the product of the remaining two dimensions.
We proceed with polynomial division or factoring:
Divide the volume polynomial by x + 2 using synthetic division or long division.
The result should be a quadratic polynomial that further factors into the product of two linear factors corresponding to the unknown dimensions.
Factor the quadratic polynomial to find the two missing dimensions.
In this case, the volume polynomial [tex]x^3 - 3x^2 - 16x - 12[/tex] can be divided by x + 2 to yield [tex]x^2 - 5x - 6[/tex], which can then be factored into (x - 6)(x + 1). Hence, the other two dimensions are x - 6 and x + 1, making option D correct.
