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.

The point (1, −1) is on the terminal side of angle θ, in standard position. What are the values of sine, cosine, and tangent of θ? plz show me how u got the answer
The values of sine, cosine, and tangent for angle θ, where (1, -1) is on its terminal side, are sin(θ) = -1, cos(θ) = 1, and tan(θ) = -1, knowing that the point lies in the fourth quadrant.
To find the values of the sine, cosine, and tangent of an angle θ where the point (1, -1) is on its terminal side, we first recognize that this point lies in the fourth quadrant of the coordinate system. In this quadrant, cosine is positive, and sine and tangent are negative.
The point (1, -1) gives us the x and y coordinates on the Cartesian plane, which correspond to the lengths of the adjacent side and the opposite side of the right-angle triangle formed by the radius (hypotenuse) from the origin to the point, and the axes. Assuming we're dealing with a unit circle (which has a radius of 1), we can directly use the coordinates (1, -1) to find the cosine and sine:
cos(θ) = x = 1sin(θ) = y = -1tangent (θ) = y/x = -1/1 = -1Hence, for angle θ, cos(θ) is 1, sin(θ) is -1, and tan(θ) is -1.

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.

Add the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of x. Find the sum of 4x3 + 2x2 - 4x + 3 and 7x3 -4x2 + 7x + 8.
Answer:
11x^3 - 2x^2 + 3x + 11
Step-by-step explanation:
we need to find the sum of 4x^3 + 2x^2 - 4x + 3 and 7x^3 -4x^2 + 7x + 8
To find the sum we add both the polynomials
4x^3 + 2x^2 - 4x + 3 + 7x^3 -4x^2 + 7x + 8
To add the polynomials we combine like terms
4x^3 + 7x^3 = 11x^3
2x^2 - 4x^2 = -2x^2
-4x+7x= 3x
3+8 = 11
So final expression is 11x^3 -2x^2 +3x+11
