ivan pays an $8 monthly service fee so he can rent movies for $1.50 each and games for 3.00 each. Last month, Ivan rented 6 movies and 5 games. Which expression and result show the total amount that Ivan spent last month on his movie and game rentals?
I think 24 dollars without the monthly fee
Answer:
Expression: 8 + m(1.5) + g(3)
Result: 32
Step-by-step explanation:
Let m represent the number of movies and g represent the number of games Ivan rent, then total amount he spent is
8 + m(1.5) + g(3)
Since he rented 6 movies and 5 games
→ 8 + 6(1.5) + 5(3)
→ 8 + 9 + 15
→ 32

There are two lines from the center of the circle labeled 5.
The lines at 90 degrees from the 5 are chords. Because both lines are the same distance from the center they are the same length.
The one on the top is labeled as 9, so the line on the bottom is also 9 units long.
X is half the length, so would b 9 /2 = 4.5 units long.

which of the following is a zero from the function f(x)=(x+3)(x-7)(x+5)? X=-7, X=-3, X=3, X=5
Answer:
x = - 3
Step-by-step explanation:
To find the zeros set f(x) = 0, that is
(x + 3)(x - 7)(x + 5) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 7 = 0 ⇒ x = 7
x + 5 = 0 ⇒ x = - 5
5. What is angel 8 use picture above
Answer:
Angle 8 = Angle 4
Step-by-step explanation:
Answer:
4. ∠3 and ∠5
5. 75°
Step-by-step explanation:
4. Same-side interior angles.
If you look at the figure, the INTERIOR angles are those between the two parallel lines (JL and MP), these are angles #3, #4, #5 and #6. The other angles are exterior angles.
The question asks for same-side... meaning both on the left of NK or on the right side of it. So, the two sets that match this are: 3 with 5 and 4 with 6.
The last option gives you ∠3 and ∠5, so that's your answer.
That makes sense since angles 1 and 2, present in all other choices, are exterior angles.
5. If ∠4 = 75 degrees, what's the value of ∠8?
Since JL and MP are parallel lines crossed by another line (NK), we know that ∠4 and ∠8 will have the same measurement. Those two angles are located on the same position compared to each other and one of the parallel line.
So, since ∠3 = 75°, ∠8 also has to be 75°, same for their opposing angles 2 and 5. While the other angles are complements... so they're 105 degrees angles.

Step-by-step explanation:
A pet store sells puppies and kittens in the ratio 5 : 4.
If their sales of puppies and kittens combined came to 36, how many puppies did they sell?
I found it by random. You times the ratio by 4 to get 36 puppies and kittens combined.
If the puppies was 5 then 5 x 4 = 20 puppies in their sales.
If the puppies was 4 then 4 x 4 = 16 puppies in their sales.
I couldn't tell if the ratio was in the according order of puppies and then kittens or if that was just saying what the ratio was about.
Let us consider the ratio to be x
So, as per the question's statement, we can write it as;
[tex]5x+4x=36[/tex]
⇒[tex]9x=36[/tex]
We will divide 9 on both the sides, we get;
⇒[tex]x=\frac{36}{9}=4[/tex]
So, for getting the number of puppy sold we have to multiply it with 5, we get;
[tex]5x=5*4=20[/tex]
They have sold 20 puppies.
Hence, the answer is [tex]20[/tex] puppies.

What is the midpoint of OA
Answer should be A if I'm not wrong.
Answer:
Option A is the correct answer.
Step-by-step explanation:
Given
The coordinates of point A = (2m, 2n)
The diagram is plotted on the graph, where O represents origin.
As we know that O is the origin whose coordinates are (0,0)
The formula for mid-point is:
Mid-point=((x_1+x_2)/2,(y_1+y_2)/2)
So,
The x-coordinate of mid-point of OA=(2m+0)/2
=2m/2
=m
The y-cooridnate of mid-point of OA=(2n+0)/2
=2n/2
=n
So the mid-point of OA is (m,n) ..

What is Equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). 6.9
Parts of an Equation
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables. As opposed to this, an equation with variables is an algebraic equation.

Find the area of the rhombus.
Please need help
Answer:
96cm2
Step-by-step explanation:
Area of rhombus=1÷2×d1×d2
=1÷2×12×16
=96
96cm². The are of the rhombus of the image is 96cm².
The key to solve this exercise is breaking down the rhombus in four equals right triangles, each triangle has the sides 10cm, 8cm and 6cm. We can calculate the area of one right triangle and multiply by 4 in order to get the total area of the rhombus.
The area of a triangle is [tex]A_{t}=\frac{bxh}{2}[/tex] where b is the base and h is the height.
The base of the one right triangle is 8cm and the height is the leg adyacent to the right angle that is 6cm. Calculating the area of the right triangle:
[tex]A_{t}=\frac{8cmx6cm}{2}=\frac{48cm^{2} }{2} =24cm^{2}[/tex]
The total area of the rhombus is [tex]A = 4A_{t}[/tex]
[tex]A = 4x24cm^{2}=96cm^{2}[/tex]
If you subtract 12 from my number and multiply the difference by-3 the result is -54 what is my number
first, make an equation:
[tex] - 54 = - 3x - 12[/tex]
then, add twelve to both sides to remove it from the right:
[tex] - 42 = - 3x[/tex]
then just divide by (-3) to get the value of x:
[tex]x = 14[/tex]
The student's question involves setting up and solving a simple algebraic equation. By following the order of operations and isolating the variable, we find that the unknown number is 30.
To solve the problem stated, 'If you subtract 12 from my number and multiply the difference by -3 the result is -54', let's establish a variable to represent the unknown number. Let's call this number 'x'. According to the problem, we need to perform two operations on this number:
1. Subtract 12 from the number x. 2. Multiply the result by -3, which should result in -54.
This establishes the equation:
(x - 12) × -3 = -54
To find x, we'll follow these steps:
Divide both sides of the equation by -3 to isolate the term (x - 12): (x - 12) = -54 / -3 (x - 12) = 18
Add 12 to both sides of the equation to solve for x: x - 12 + 12 = 18 + 12 x = 30
Therefore, the number we're looking for is 30.

Find the solution set of the inequality 14- 3x < -1.14
Final answer:
To solve the inequality 14 - 3x < -1.14, subtract 14 from both sides, then divide by -3 and remember to reverse the inequality, resulting in the solution set x > -5.05.
Explanation:
To find the solution set of the inequality 14 - 3x < -1.14, follow these steps:
Subtract 14 from both sides of the inequality: -3x < -1.14 - 14.Now, the inequality looks like -3x < -15.14.Divide both sides of the inequality by -3, remembering that dividing by a negative number reverses the inequality: x > 15.14 / -3.The solution is x > -5.05.Therefore, the solution set for the inequality is all real numbers greater than -5.05.
How many possible 7 digit phone numbers can be created from the digits 0 through 9 if numbers cannot be repeated and the first number cannot equal 0?
A.181,440
B.544,320
C.604,800
D.10,000,000
Please select the best answer from the choices provided
A
B
C
D
The correct answer is C. 604,800.
To calculate this, we can use the formula for permutations:
P(n, k) = n! / (n-k)!
In this case, we have 9 digits (0-9), and we want to create a 7-digit phone number. Since the first digit cannot be 0, we have 9 choices for the first digit, and 9 remaining choices for each subsequent digit (since numbers cannot be repeated).
So, the total number of possible phone numbers is:
P(9, 7) = 9! / (9-7)! = 9 × 8 × 7 × 6 × 5 × 4 × 3 = 604,800
Therefore, the correct answer is C. 604,800.
Please help! The figure is a rhombus, and I am trying to find the measure of angle ADB
Answer:
86 - 9x
Step-by-step explanation:
In a rhombus, adjacent angles are supplementary. So:
∠ADE + ∠EDC + ∠DCE + ∠ECB = 180
Also, the diagonals of a rhombus are perpendicular. Since the sum of a triangle's angles add up to 180:
∠EDC + 90 + ∠DCE = 180
∠EDC + ∠DCE = 90
Substituting:
∠ADE + 90 + ∠ECB = 180
∠ADE + ∠ECB = 90
∠ADE + 9x + 4 = 90
∠ADE = 86 - 9x
∠ADB is the same as ∠ADE, so the answer is 86 - 9x.
Angle ∠ADB is 41°.
RhombusIt is a polygon that has four sides and four corners. The sum of the internal angle is 360 degrees. In Rhombus opposite sides are parallel and all sides are equal. And its diagonals intersect at the right-angle.
Given
A rhombus ABCD,
∠DCA = 13x - 16
∠ACB = 9x + 4
To findThe measure of ∠ADB.
How to get the measure of ∠ADB?We know that the angle ∠DCA and ∠ACB are equal.
13x - 16 = 9x + 4
13x - 9x = 4 + 16
4x = 20
x = 5
So the angle ∠DCA and ∠ACB will be
∠DCA = 13x - 16 = 64 - 16 = 49
∠ACB = 9x + 4 = 45 + 4 = 49
The sum of the internal angle is 360 degrees
∠ABC + ∠BCD + ∠CDA + ∠DAB = 360
∠CDA + ∠BCD + ∠CDA + ∠BCD = 360
∠ABC + ∠BCD = 180
∠CDA + 98 = 180
∠CDA = 82
So we know
2 x ∠ADB = ∠CDA
2 x ∠ADB = 82
∠ADB = 41
Thus, Angle ∠ADB is 41°.

Answer:
(D) 3, 3, 6
Step-by-step explanation:
The triangle inequality says the sum of the shortest two legs must be longer than the longest. In the case of {3, 3, 6}, the sum is exactly equal to the longest, so the "triangle" will look like a line segment and have zero height and zero area,
Some authors describing the triangle inequality find that to be an acceptable condition. Apparently the author of this question does not.
