The awnser Choice for each on is( one solution no solution infinity many solutions of all real numbers ) plz help
Answers
1: one solution
Explanation: We see that the variable x is equal to 9 (and only 9). Therefore there is only one solution
2: infinitely many solutions
Explanation: When an equation has infinitely many solutions, it means that any real number (aka all real numbers) would satisfy that equation. For example 2x = 2x. Any number you plug in for x would result in both sides being equal. So you know an equation has infinitely many solutions if both sides are the same
3: no solution
Explanation: 7 does not equal 4 so you can't solve this equation.
4: no solution
Explanation: 7 is not less than 7, that is impossible, so there is no solution.
5: one solution
Explanation: 8 is greater than or equal to -2, so this inequality is true, meaning it represents one solution

You have two values - the height and length and - and you are missing the width.
The volume (353 m^3) of this rectangular prism is equal to b(ase) x h(eight) x w(idth).

352/88 = 4

Amanda wants to buy 15 dollars worth of candy. The gummy worms cost $1.50 per pound and the peanut
butter cups cost $3 per pound. Let x be the amount of gummy worms in pounds and y be the amount of peanut
butter cups in pounds.
Answers
Answer:
C = $1.50x + $3y
Step-by-step explanation:
Using the information provided we can create an equation to model the total dollar cost of Amanda's purchase when visiting the candy store. To do this we need to multiply each candies individiual cost by the amount of each candy they are purchasing. Then we add together all of these values to get the final total cost which would be represented by C.
C = $1.50x + $3y

Answers
Complete Question:
A pedestal for a statue is made with 405 cubic feet of concrete. A rectangular prism with a height of 9 feet.
What is the area of the base of the pedestal?
Answer:
45 square feet
Step-by-step explanation:
Given the following data;
Volume of pedestal = 405 ft³
Height of rectangular prism = 9 ft
To find the area of the base of the pedestal;
Volume of pedestal = base area * height
405 = base area * 9
Base area = 405/9
Base area = 45 square feet.
Therefore, the area of the base of the pedestal is 45 square feet.
Answer:
45 square feet

a) Find the coordinates of M the midpoint of [AB]
b) Find the coordinates of G the center of gravity of the triangle ABC .
Answers
Answer:
The answer is below
Step-by-step explanation:
a) If O(x, y) is the midpoint between two points X(x₁, y₁) and Y(x₂, y₂)m then the coordinates of O is:
x = (x₁ + x₂)/2; y = (y₁ + y₂) / 2
Since M(x, y) is the midpoint of AB, then the coordinates of M is:
x = (0 + 5) / 2 = 2.5; y = (1 + 0)/2 = 0.5
M = (2.5, 0.5)
b) The center of gravity is gotten by finding the average of the x coordinates and the y coordinates of the vertices of the triangle.
Let O(x, y) be the center of gravity of triangle ABC, hence;
x = (0 + 5 + 4) / 3 = 3
y = (1 + 0 + 2) / 3 = 1
O = (3, 1)

A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function
h = -16t2 + 64t + 960.
What is the maximum height?
960 feet
1008 feet
1024 feet
1152 feet
Answers
The maximum height that the ball will reach is the one in the third option, 1,024 feet.
What is the maximum height?We know that the height is modeled by a quadratic function:
H = -16t² + 64t + 960.
Where t represents the time in seconds, and H is the height in feet.
To find the maximum height we need to find the vertex of the quadratic, in this case, the vertex is at:
t = -64/2*-16 = 2
Evaluting there we will get:
H(2) = -16*2² + 64*2 + 960 = 1,024
That is the maximum height that the ball will reach.

A teacher has 20 students. Each student is paying $12.50 for a ticket to see a play during a field trip. The teacher collects their money for two weeks. In the first week, 14 students pay for their ticket. In the second week, the rest of the students pay for their ticket. How much did the teacher collect in the second week?
Answers
Answer:
$75
Step-by-step explanation:
Steps to determining the answerDetermine the number of students that would pay in the second week. This can be known by subtracting 14 from 20. 20 is the total number of students. 14 is the number of students that paid in the first week. Multiply the answer gotten from one above by the price of the ticket20 - 14 = 6
6 students would pay in the second week
6 x $12.50 = $75
The teacher would collect $75 in the second week
