Together, teammates pedro and ricky got 2671 base hits last season. pedro had 277 more hits than ricky. how many hits did each player have?
To find out how many hits each player had, we set up a system of equations and solve for the variables. Pedro had 2474 hits and Ricky had 1197 hits.
Explanation:To solve this problem, we need to set up a system of equations. Let's represent the number of hits Pedro had as x and the number of hits Ricky had as y. We are given that their combined hits is 2671, so we can write the equation:
x + y = 2671
Additionally, we are given that Pedro had 277 more hits than Ricky. This can be represented as:
x = y + 277
We can now substitute the second equation into the first and solve for y:
y + 277 + y = 2671
2y = 2394
y = 1197
Now we can substitute the value of y back into the first equation to solve for x:
x + 1197 = 2671
x = 2474
Therefore, Pedro had 2474 hits and Ricky had 1197 hits.

Given triangle JKL, sin 38 degree equals
Answer:
B. [tex]\text{cos}(52^{\circ})[/tex].
Step-by-step explanation:
We have been given a right triangle. We are asked to complete our given statement.
[tex]\text{sin}(38^{\circ})[/tex] equals ___.
We will use identity [tex]\text{sin}(x)=\text{cos}(90-x)[/tex] to solve our given problem.
[tex]\text{sin}(38^{\circ})=\text{cos}(90^{\circ}-38^{\circ})[/tex]
[tex]\text{sin}(38^{\circ})=\text{cos}(52^{\circ})[/tex]
Therefore, [tex]\text{sin}(38^{\circ})[/tex] equals [tex]\text{cos}(52^{\circ})[/tex].

one of the advantages to an employer of pay employees piece-rate or commissions is that the employees paid based solely on their performance what is one disadvantage of this type of pay
Disadvantages of the Piece-Rate Pay System:
Hindered Production -- It's virtually impossible to predict how much product can be created within a set time under this system, because the system doesn’t easily lend itself to regulating and encouraging a production line.
Sick or Injured Workers -- Working for piece-rate pay means that workers might come to work when they are ill, thereby risking the health of their coworkers. This could shut down or seriously reduce production output. Additionally, depending on the materials and equipment, if workers are working too quickly in an attempt to produce more, workers could potentially injure themselves, which could open up the company to liability.
Reduced Quality -- When the focus is on quantity, the output the quality may suffer. Such a system requires dedicated employees who are determined to learn their craft thoroughly and then to increase the output. Employees are human, however, and it can be difficult to work at a rapid pace over a long duration. This can mean that employees may continue to work at a rapid pace but that production may produce items of reduced quality.

Where does f(x) = 3x2 – 11x – 4 intersect the x-axis?
Answer:
f(x) intersect the x-axis ate ( 4 , 0 ) and ( -1/3 , 0)
Step-by-step explanation:
Given function, [tex]f(x)=3x^2-11x-4[/tex]
We need to find this function cuts x-axis at what point.
let, [tex]y=3x^2-11x-4[/tex]
We know that points on x-axis has y-coordinate equal to 0.
So, we put y = 0 to find value of x.
By putting y = 0, we get
[tex]0=3x^2-11x-4[/tex]
[tex]3x^2-11x-4=0[/tex]
solving by quadratic formula,
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\frac{-(-11)\pm\sqrt{(-11)^2-4\times3\times(-4)}}{2\times3}[/tex]
[tex]x=\frac{11\pm\sqrt{121+48}}{6}[/tex]
[tex]x=\frac{11\pm\sqrt{169}}{6}[/tex]
[tex]x=\frac{11\pm13}{6}[/tex]
[tex]x=\frac{11+13}{6}\:\:and\:\:x=\frac{11-13}{6}[/tex]
[tex]x=\frac{24}{6}\:\:and\:\:x=\frac{-2}{6}[/tex]

sarah competes in a long jump competion. her first jump is 4.25m. her best jump is 12% more than this. however, her best jump is 15% lower than the winning jump. work out the of the winning jump.
The winning jump is approximately 5.60 meters.
1. We start by denoting Sarah's first jump distance as [tex]\( x \)[/tex] meters.
2. We calculate Sarah's best jump distance, which is 12% more than her first jump, giving [tex]\( 1.12x \).[/tex]
3. We know Sarah's best jump is 15% lower than the winning jump, so we set up an equation equating her best jump to 0.85 times the winning jump.
4. Solving for the winning jump, we find [tex]\( \frac{1.12x}{0.85} \).[/tex]
5. Substituting the value of Sarah's first jump [tex](\( x = 4.25 \))[/tex], we find that the winning jump is approximately 5.60 meters.
Let's denote Sarah's first jump distance as [tex]\( x \)[/tex] meters.
According to the problem:
- Sarah's best jump is 12% more than her first jump: [tex]\( 1.12x \).[/tex]
- Sarah's best jump is 15% lower than the winning jump.
Let's calculate Sarah's best jump distance:
[tex]\[ \text{Best jump} = 1.12x \][/tex]
Now, let's find the winning jump distance:
[tex]\[ \text{Best jump} = 0.85 \times \text{Winning jump} \][/tex]
Since Sarah's best jump equals 0.85 times the winning jump:
[tex]\[ 1.12x = 0.85 \times \text{Winning jump} \][/tex]
To find the winning jump distance, we'll divide Sarah's best jump by 0.85:
[tex]\[ \text{Winning jump} = \frac{1.12x}{0.85} \][/tex]
Now, let's substitute the value of Sarah's first jump:
[tex]\[ \text{Winning jump} = \frac{1.12 \times 4.25}{0.85} \][/tex]
[tex]\[ \text{Winning jump} = \frac{4.76}{0.85} \][/tex]
[tex]\[ \text{Winning jump} \approx \frac{4.76}{0.85} \][/tex]
[tex]\[ \text{Winning jump} \approx 5.60 \][/tex]
So, the winning jump is approximately 5.60 meters.

Step-by-step explanation:
Chloe draws three parallelograms. In each figure, she measures a pair of angles, as shown. What is a reasonable conjecture for Chloe to make by recognizing a pattern and using inductive reasoning?
a) In a parallelogram, consecutive angles are supplementary.
b) In a parallelogram, all angles are congruent.
c) In a parallelogram, all angles are supplementary.
d) In a parallelogram, consecutive angles are congruent.
The conjecture Chloe can make based on the given information is that in a parallelogram, consecutive angles are congruent.
Explanation:Chloe's conjecture, based on the pattern she observed, would be that in a parallelogram, consecutive angles are congruent. To support this conjecture, we can explain that a parallelogram has opposite sides that are parallel, and therefore, the opposite angles are congruent. Since the consecutive angles are adjacent to these opposite angles, they must also be congruent.
