From inspection, we can see that the center of the circle = (0, 0)

Layla is baking a Double Chocolate Chocolate Chip cake. For this recipe, she will need one bag of flour and a number of bags of chocolate chips. At the grocery store, she sees that a bag of flour costs $3.59 and each bag of chocolate chips, c, costs $2.75. Write an algebraic expression to represent the total amount she will spend at the store.
Answers
Answer:
2.75c +3.59
Step-by-step explanation:
She only needs one bag of flour so it is a constant 3.59. She needs multiple bags of chocolate chips which is unknown so that will be c times the 2.75 for each bag

2.5 times 1,760 in steps.
Answers
Answer:
2.5 times 1760 is 4400
Step-by-step explanation:
math lol
Answer:
. We assume, that the number 1760 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 1760 is 100%, so we can write it down as 1760=100%.
4. We know, that x is 2.5% of the output value, so we can write it down as x=2.5%.
5. Now we have two simple equations:
1) 1760=100%
2) x=2.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
1760/x=100%/2.5%
6. Now we just have to solve the simple
equation, and we will get the solution we are looking for.
7. Solution for what is 2.5% of 1760
1760/x=100/2.5
(1760/x)*x=(100/2.5)*x - we multiply both sides of the equation by x
1760=40*x - we divide both sides of the equation by (40) to get x
1760/40=x

a
triangle
The measure of the First angle of
is 25 degree less than the measure of the
Second angle. The measure of the third angle
of the triangle is triple the measure of the
second angle.
Answers
Alright, lets say the measure of the 3rd angle (the smallest one) is x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.
(x + 25) + 3x + x = 180
5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)
31 + 25 = 56o (first angle)
3 × 31 = 93o (second angle)
56 + 93 + 31 = 180

Two water balloons were launched into the air at different moments and collided. The water balloons were modeled by the quadratic functions: y=-7x2 + 26x + 6 and
y=-6x2 + 25x + 4 where y represents the height in meters and x represents the time in seconds after the launch. What is the time in seconds that the balloons
collided at the highest point?
O 1.75 seconds
O 20 seconds
O2 25 seconds
O 2.5 seconds
Answers
The time in seconds that the balloons collided at the highest point is; B: 2.0 seconds
What are quadratic equations?We are told that the water balloons were modeled by the quadratic functions:
y = -7x² + 26x + 6 and y = -6x² + 25x + 4
where;
y = the height in meters
x = the time in seconds after the launch
The time at which they will collide has to be at the same height.
Thus;
-7x² + 26x + 6 = -6x² + 25x + 4
Rearranging this gives;
x² - x - 2 = 0
Using online quadratic equation solver gives us x = 2 or -1. We will take the positive one as x = 2.0 seconds
