The number of hits by each player are 1195 and 1470 hits, respectively

Let's call the number of hits that Ricky got "x".

Then, Pedro got x + 275 hits.

The total number of hits for both players is x + (x + 275) = 2665

Solving for x, we get 2x + 275 = 2665

Subtracting 275 from both sides,

We get 2x = 2665 - 275 = 2390

Dividing both sides by 2,

We get x = 2390 / 2 = 1195

So Ricky got 1195 hits and Pedro got 1195 + 275 = 1470 hits.

The location of the waterfall on the graph will be (3,1). Instead of going down down,  Rodrigo goes 4 units upward direction.

Coordinates are defined as a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x-axis (horizontal) and y-axis are the two axes that make up a coordinate plane (vertical).

Given that the location of the entrance is at (6, 5).

To reach the waterfall, you need to go 3 km to the left and 4 km down from the park entrance.

The x-coordinate decreases to the left side of a point and increases to the right side of a point.

The y-coordinate decreases to a downward point and increases upward a point.

The x-coordinate of the waterfall is 6 - 3 =3

The y-coordinate of the waterfall is 5 - 4 = 1.

The coordinate that represents the location of a point is (3,1).

Answer:

B.    175.84 square inches

Step-by-step explanation:

The pizza is shaped like a circle

Area of a circle = π r² where r is the radius

r = d/2 where d = diameter

Here d = 16 in

r = 16/2 = 8

Total area of pizza = π · 8² = 64 π

If 1/8th of the pizza was consumed balance = 1-1/8 = 7/8

7/8 of the total area = 7/8 x 64π = 56π = 175.84 square inches

This is the area of the remaining portion of the pizza

The equation in standard form when the line is passing through point (0,-3) and parallel to x - 5y = 75 is 5y - x + 15

What is equation of a straight line ?

Equation of straight line as follows , y = mx + b

where m is the slope of line.

Given equation ,

x - 5y = 75

and the points are (0,-3)

First lets find the slope of a line

we get,

x - 5y = 75

5y = x - 75

y = 1/5 x  - 15

m = 1/5

Here the point (0,-3) and slope m = 1/5
Therefore,

The equation of the line

y + 3  = 1/5  (x-0)

5y + 15 = x

5y - x + 15

Therefore, The equation in standard form when the line is passing through point (0,-3) and parallel to x - 5y = 75 is 5y - x + 15

The rquired equation of the line is x + 2y = - 10

The slope-intercept form of a line is given by

Where m = slope and c = y-intercept  

Note: The slope of two parallel lines will have the same slope

Here we have

The point (-6, -8) and the line x - 2y = 6 --- (1)

Let the equation y = mx + c ---- (2)  is the equation of the line  that passes through (-6, -8) and parallel to x - 2y = 6  

As we know the parallel  lines will have the same slope

=> Slope of line (1) = Slope of line (2)

Here x - 2y = 6

=> 2y = - x + 6

=>  y = -x/2 + 3  which is in the form of y = mx + c

=> Slope of line = - 1/2

Therefore, the Slope of lines (2) = -1/2

=> y = (-1/2)x + c

=> 2y = -x + 2c --- (3)

Given that line passes through (-6, -8)

=> 2(-8) = - (-6) + 2c

=> - 16 = + 6 + 2c

=> 2c = -10

=> c = -5

=>  y = -x/2 + (-5)

=>  y = -x/2 - 5

=> 2y = - x - 10

=> x + 2y = - 10

Therefore,

The required equation of the line is x + 2y = - 10

The measure of the angles of the parallelogram are: x = 90 degrees, y=   122degress and z=90 degrees

A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides

Remember that the opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

This implies that y + 58 = 180

Making y the subject of the relation

y=180-58

y=122⁰

Also, since the other two opposite angles are not given, then it means that x=y = 180/2 = 90

this therefore means that x= 90, y= 122 and z= 90 degrees

The value of the x for the given triangle is 30.67.

Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Given a right triangle,

the base angle is 61° and the length of the base is 17

using tangent to find the value of x

tanФ = perpendicular/base

here base = 17

perpendicular = x

Ф = 61°

tan61 = x/17

x = 17tan61

x = 30.67

Hence the value of x is 30.67.

The ratio of the side lengths, yellow to green

We see yellow is 36 and green is 60, so we just put that slash mark in between as indicated in the directions, giving us

36/60. We can reduce this to it's simplistic form of 3/5

The ratio of the perimeters, yellow to green.

To find the perimeter, we multiply the side by 5

Yellow; 36x5= 180

Green; 60x5= 300

We put that ratio slash... 180/300. Reducing it comes out to 90/150 > 30/50 > 3/5 also...

And that's because the polygons are similar.

Since the polygons are similar... what would be the ratio for the areas...

Yep, 3/5

Last is to find the area of the green.

The yellow is 45 and the ratio is 3/5. We can write the equation as a ratio

The amount of energy received from the Sun decreases with increasing distance, so the planets farthest from the Sun receive the least energy and therefore have the coolest surface temperatures.
