1. Victoria has a total of 65 dimes and quarters worth $10.70. How many of each type of coin does she have?
2. Max has two part-time jobs. He makes $12 per hour mowing lawns and $15 per hour tutoring students. Over the
weekend he worked for a total of 14 hours and made a total of $192. How many hours did he work for each job?
Answer:
1) Let D be the number of dimes and Q be the number of quarters. We can set up the following system of equations to represent the given information:
D + Q = 65
0.1D + 0.25Q = 10.70
The first equation represents the total number of coins Victoria has, and the second equation represents the total value of those coins in dollars. Solving this system of equations will give us the number of dimes and quarters Victoria has.
2) Let M be the number of hours Max spends mowing lawns and T be the number of hours he spends tutoring. We can set up the following system of equations to represent the given information:
M + T = 14
12M + 15T = 192
The first equation represents the total number of hours Max worked over the weekend, and the second equation represents the total amount of money he made during that time. Solving this system of equations will give us the number of hours Max spent on each job.

Answer: The ratio 18:26 simplified is 9:13.
Step-by-step explanation:
To simplify the ratio 18:26, we find the greatest common divisor of 18 and 26, and then we divide 18 and 26 by the greatest common divisor.
The greatest common divisor that you can use to simplify 18:26 is 2. Which means the answer to ratio 18:26 simplified is: 9:13

Find the zeros of the function.
Enter the solutions from least to greatest.
f(x) = (-x - 2) (-2x - 3)
lesser x =
greater x =
PLEASE I NEED HELPPPP
Answer:
lesser x= -2
greater x= -3/2 or -1.5
Step-by-step explanation:
f(x)=(-x-2)(-2x-3)
-x-2=0
+2 +2
-x=2
-1 -1
x=-2
-2x-3=0
+3 +3
-2x=3
-2 -2
x=-3/2
The zeros of the function are x = -2 and x = -1.5.
The lesser value of x is -2, and the greater value of x is -1.5.
What are the zeros of the function?A function's zeros, also known as roots or solutions in mathematics, are the values of the independent variable (typically represented as x) for which the function evaluates to zero. In other terms, a function's zeros are the x-values that make the function equal to zero.
To find the zeros of the function f(x) = (-x - 2) (-2x - 3), we set the function equal to zero and solve for x:
(-x - 2) (-2x - 3) = 0
To find the zeros, we need to consider each factor separately and set them equal to zero:
First factor: -x - 2 = 0
Solving for x, we add 2 to both sides:
-x = 2
Multiplying both sides by -1 to isolate x:
x = -2
Second factor: -2x - 3 = 0
Solving for x, we add 3 to both sides:
-2x = 3
Dividing both sides by -2 to isolate x:
x = -3/2 or -1.5
So, the zeros of the function are x = -2 and x = -1.5.
Therefore, the lesser value of x is -2, and the greater value of x is -1.5.

Therefore , the solution of the given problem of trigonometry comes out to be Cos 2x = -0.760355.
Trigonometry is what?The study of relationships among triangle angles and angles is known as trigonometry. Mathematical modeling is a fundamental idea in all of geometry because it can be used to reduce any straight-sided form to a collection of triangles. Amazingly complex connections exist between trigonometry and other areas of mathematics, particularly mathematics, real or complicated, infinite series, logarithms, and infinite series.
Here,
Given : Cosx = 9/26 (First quadrant)
To find : Cos2x
We use the formula:
=>Cos2x = 2Cos²x -1
=> Cos2x = 2(9/26)² - 1
=> Cos 2x = -0.760355
Therefore , the solution of the given problem of trigonometry comes out to be Cos 2x = -0.760355.

The volume of a cylinder is 40 f3. Which expression represents the volume of a cone with the same base and height as
the cylinder?
O 3(40) ft
O
1
40
O (40) At
o 3 (402)
Answer:
Option (3)
Step-by-step explanation:
Volume of the cylinder = 40 ft³
Since, volume of a cylinder is given by the expression,
V = [tex]\pi r^{2}h[/tex]
Here, r = radius of the circular base
h = Height of the cylinder
40 = [tex]\pi r^{2}h[/tex]
[tex]h=\frac{40}{\pi r^2}[/tex] ------(1)
Volume of a cone = [tex]\frac{1}{3}\pi r^{2} h[/tex]
By substituting the value of 'h' from equation (1)
Volume of the cone = [tex]\frac{1}{3}\pi r^{2}(\frac{40}{\pi r^{2} } )[/tex]
= [tex]\frac{1}{3}(40)[/tex] ft³
Therefore, Option (3) will be the correct option.
HELP ASAP! (20 POINT CUZ I NEED DONE ASAP) In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 7 times out of 10 attempts. Tasha has hit the ball 10 times out of 16 attempts. Which player has a ratio that means they have a better batting average?
Tasha, because she has the lowest ratio since 0.7 < 0.625
Tasha, because she has the highest ratio since 56 over 80 is greater than 50 over 80
Jana, because she has the highest ratio since 56 over 80 is greater than 50 over 80
Jana, because she has the lowest ratio since 0.7 < 0.625
Tasha, because she has the lowest ratio since 0.7 < 0.625

Which property is illustrated by the statement below? 4(3+2)=4(3)+4(2)
Distributive property is illustrated by the statement given as 4[3+2]=4[3]+4[2]
What is distributive property?The distributive property is defined as an expression of the form A(B + C). This property is known by distributive law and applies to subtraction also. This can be solved by a multiplication over addition operation that is written as:
A(B + C) = AB + AC
Distributive property is the sum of two numbers times a third number is equal to the sum of each add end times the third number.
Since the general rule is that:
a(b + c) = ab + ac
Then, 4[3+2]=4[3]+4[2]
Therefore, the given statement elaborates the Distributive property.
