Answer:
720 shares
Step-by-step explanation:
Find 60% of 1,200, to figure out how many shares Jillian has.
Change 60% to decimal
0.6
Multiply with the total shares
0.6 x 1,200 = 720
720 shares
Jillian owns 720 shares in a catering corporation.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have to determine 60% of 1,200, to figure out how many shares Jillian has.
Convert 60% into a decimal
⇒ 0.6
Multiply with the total shares
⇒ 0.6 × 1200
⇒ 720
Hence, Jillian owns 720 shares in a private catering corporation.

Which point is an x-intercept of the quadratic function f(x) = (x – 4)(x + 2)?
Answer:
x = - 2, x = 4
Step-by-step explanation:
Given
f(x) = (x - 4)(x + 2)
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0 ← in standard form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4 → (4, 0 )
x + 2 = 0 ⇒ x = - 2 → (- 2, 0 )
In a sample of 94 widgets, 4 were defective. How many defective widgets would you expect in a sample of 282 widgets?
Answer:
12
Step-by-step explanation: 282 divided by 94 = 3
4x3=12
Answer:
12 defective widgets
Step-by-step explanation:
Here we calculate the "experimental probability:" 4 defective widgets out of 94 widgets comes out to a probability of being defective of 4/94, which of course could be reduced.
But we can go ahead and calculate the expected number of defective widgets by mult. that 282 widgets by the probability 4/94:
282 4
------- * ------- = 12

In this sample of 282 widgets, we could expect that 12 will be defective.
Which equation can be used to find 40 percent of 25?
100x4 400
40x4 = 16
40x4
160
25x4 - 100
40-4 10
100-4 - 25
Answer:
Step-by-step explanation:
40%=0.4
0.4*25=10
To calculate 40 percent of 25, you use the equation 0.40 x 25. This equation multiplies the decimal form of 40 percent by the total, which in this case is 25, resulting in the value of the part that represents 40 percent.
To find 40 percent of 25, you can use the equation that incorporates the base value (25) and the percentage you want to find (40%). In this case, the equation you're looking for is 0.40 x 25, which will give you the answer for what is 40 percent of 25.
Percentages can be calculated by using the formula: 'part over total, times one hundred, equals percent'. For example, if you have 25 students and want to find out what 40% of that number is, you would calculate 40/100, which is 0.40, and multiply by 25. The equation 0.40 x 25 is thus used to solve for the desired percentage.

A rectangle has an area of 90 square centimeters and a height of 12.5 centimeters. What is the length of the base?
Answer: l = 7.2
Step-by-step explanation:
90/12.5 = 7.2
7.2 * 12.5 = 90
Answer:
length of the rectangle is 7.2 centimeters.
Step-by-step explanation:
Area of the rectangle has been given as 90 square centimeters.
Height of the rectangle = 12.5 centimeters
Now we have to calculate the length of the rectangle.
Since, Area of the rectangle = Length × height
90 = 12.5 × length
Length = [tex]\frac{90}{12.5}[/tex]
= 7.2 centimeters
Therefore, length of the rectangle is 7.2 centimeters.

HELP A BROTHA OUT!!!
The solutions to the quadratic equation 3x^2 - 7x - 1 = 0, using the quadratic formula, are x = [7 + sqrt(61)]/6 and x = [7 - sqrt(61)]/6.
Explanation:This question pertains to the solving of a quadratic equation using the quadratic formula. The quadratic formula is given by x = [-b ± sqrt(b^2 - 4ac)]/2a. In equation 3x^2 - 7x - 1 = 0, comparing it with the standard form of quadratic equation ax^2 + bx + c = 0, we can assign: a = 3, b = -7, and c = -1. Substituting these values into the formula, we get: x = [7 ± sqrt((-7)^2 - 4*3*(-1))]/2*3 = [7 ± sqrt(49 + 12)]/6 = [7 ± sqrt(61)]/6. So, the solutions to the equation are x = [7 + sqrt(61)]/6 and x = [7 - sqrt(61)]/6.

When solving p^2 + 5 = 8p - 7. Kate wrote p^2 + 12 = 8p. The property she used was:
1) the associative property
2) the commutative property
3) the distributive property
4) the addition property of equality
Answer:
4)
Step-by-step explanation:
Because they just added the same equality. And when you move the -7 over the equal sign it makes it positive so it would be p^2 + 5 + 7 = 8p and that makes it p^2 + 12 = 8p
The property used by the kate to write the function p^2 + 5 = 8p - 7 as p^2 + 12 = 8p is the addition property of equality.
Given to us
When solving p^2 + 5 = 8p - 7.
Kate wrote p^2 + 12 = 8p.
What property is used by Kate?As we can see Kate has simply added the number one, therefore, she had used the addition property of equality.
[tex]p^2 + 5 = 8p - 7\\\\p^2+5+7=8p\\\\p^2 + 12=8p[/tex]

Answer:
[tex]2x+3y=1470[/tex]
Step-by-step explanation:
Givens
The profit on every sandwich is $2.The profit on every wrap is $3.Sal made $1470 in profits.So, [tex]x[/tex] represents the number of sandwiches and [tex]y[/tex] represents the number of wraps, so the profit on each food is
[tex]2x[/tex] and [tex]3y[/tex], so the sum of them must be equal to $1470, as follows
[tex]2x+3y=1470[/tex]
Which is a linear equation, that means if we graph, it would be a line.
To graph this, we just need to find two points.
For [tex]x=0[/tex], let's find [tex]y[/tex]
[tex]2x+3y=1470\\2(0)+3y=1470\\y=\frac{1470}{3}=490[/tex]

Answer:
3√5 or ≈6.7082
Step-by-step explanation:
1) √45
2) Factor out the perfect square: √3²×5
3) The root of a product is equal to the product of the roots of each factor: √3²√5
4) Reduce the index of the radical and exponent with 2: 3√5
5) Solution: 3√5 or ≈ 6.7082
after removing the perfect square factor from inside the square root of 45, we are left with 3√5.
To remove all perfect squares from inside the square root of √45, we need to factorize 45 and separate the perfect square factors.
The prime factorization of 45 is 3 × 3 × 5. Since 3 is repeated twice, it represents a perfect square factor.
We can rewrite the square root of 45 as the square root of (3 × 3 × 5). Using the property of square roots (√ab = √a × √b), we can simplify it as √(3 × 3) × √5.
The square root of 3 × 3 equals 3, so the expression simplifies to 3√5.
Therefore, after removing the perfect square factor from inside the square root of 45, we are left with 3√5.

Angles a= 3x + 5 b= 5x - 18. C= 7x - 2
Answer:
x = 13.
So the 3 angles are a = 44, b = 47 and c = 89 degrees.
Step-by-step explanation:
If these are the angles are the 3 angles of a triangle they sum to 180 degrees, so:
3x + 5 + 5x - 18 + 7x - 2 = 180
15x - 15 = 180
15x = 195
x = 195/15
x = 13.
To find the values of angles a, b, and c given by the expressions 3x + 5, 5x - 18, and 7x - 2, we set up and solve equations involving these expressions. Once we find the value of x, we substitute it back into the expressions to find the angles.
Explanation:The question asks about angles given by the expressions a= 3x + 5, b= 5x - 18, and c= 7x - 2. In order to find the values of x and the corresponding values of angles a, b, and c, we need to set up and solve equations involving these expressions.
We can equate these expressions to given angles or to each other, and solve for x. Once we find the value of x, we can substitute it back into the expressions to find the angles.
For example, to find angle a, we substitute the value of x into the expression 3x + 5. Similarly, we substitute the value of x into the expressions 5x - 18 and 7x - 2 to find angles b and c, respectively.
