A ticket to a movie theater costs $5.25. A large lemonade costs $3 and a small popcorn costs $1.55. What is the total cost of going to the movie and buying a large lemonade and a small popcorn?
Answer:
Your answer is 9.8
Step-by-step explanation:
Well, this is fairly simple... You're adding the cost for the move, the cost for large lemonade, and the cost for a small popcorn.
5.25+3= 8.25 | 8.25+1.55= 9.8
Your answer is 9.8
Answer:
$9.80
Step-by-step explanation:
Add the cost of the ticket, lemonade, and popcorn.
total cost=5.25+3+1.55
total cost=9.8
Which means $9.80

Step-by-step explanation:
How many numbers x between 1 and 100 (inclusive) have the property that x2+x3 is a perfect square?
(Please help. I'm suffering)
=========================================================
Explanation:
Factor the given expression
x^2+x^3
x^2*1+x^2*x
x^2(1+x)
x^2(x+1)
We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.
In short, we don't need to worry about the x^2 portion.
--------------------
The only thing of importance is the x+1 factor.
The x+1 must be a perfect square so that the original expression is as well.
Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}
If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".
Subtract 1 from each item to end up with this modified set
{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}
--------------------
Every item mentioned in that second set will make x^2+x^3 to be a perfect square.
For example, let's pick x = 15
x^2(x+1) = 15^2*(15+1)
x^2(x+1) = 15^2*16
x^2(x+1) = 15^2*4^2
x^2(x+1) = (15*4)^2
x^2(x+1) = 60^2
This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.
There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.
--------------------
To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.

Which equation represents a line that passes through (5, 1) and has a slope of 1/2?
Oy-5= 1/2(x-1)
oy- į = 5(x-1)
oy-1 = 1/2(x–5)
oy-1 = 5(x-1/2)
Answer:
C. y - 1 = 1/2(x - 5)Step-by-step explanation:
Use the point- slope form:
y - y₁ = m(x - x₁)Substitute know values:
y - 1 = 1/2(x - 5)The matching choice is C
The correct equation which represents a line that passes through (5, 1) and has a slope of 1/2 is,
y - 1 = 1/2(x - 5)
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
A equation of a line that passes through (5, 1) and has a slope of 1/2.
Now, Use the point- slope form:
⇒ y - y₁ = m(x - x₁)
Hence, Substitute all the values:
y - y₁ = m(x - x₁)
y - 1 = 1/2(x - 5)
Thus, The correct equation which represents a line that passes through (5, 1) and has a slope of 1/2 is,
y - 1 = 1/2(x - 5)

Good day dear friends,
The expression 2L + 2W is used to find the perimeter of a rectangle with length L and width of W.
What is the perimeter of a rectangle with length 15cm and width 4cm?
Show your work.
A. 38
B. 60
C. 239
D. 23
Answer:
A, 38cm
Step-by-step explanation:
since u have to take 15cm (the length) then multiply by 2 to take both the sides of the rectangle
then you have to take the width 2 times to take the perimeter and add it up. so 15x2 and 4x2 added is 38. there!
What is the area of a triangle that has a height of 60 and a base length of 7 feet
Answer:
210
Step-by-step explanation:
so the formula for the area of a triangle is base × height ÷ 2
so you do 60 × 7 = 420 then divide by 2 = 210
round to nearest ten 8,990.97
Answer:
8990
Step-by-step explanation:
The 9 underlined is in the tens place.
8990.97 ⇒ 8990
Since you can't round up, you replace everything after the underlined 9 with 0's.
8990.00 = 8990

Answer:
315 = 5*3*7*3
Step-by-step explanation:
This diagram shows a pre-image △ABC, and its image, △A′′B′′C′′, after a series of transformations. Select from the drop-down menus to correctly complete the statements. △ABC is Choose... to become △A′B′C′. Then △A′B′C′ is Choose... to become △A′′B′′C′′ . Because the transformations are Choose... , the pre-image and image are Choose... . Triangles on a coordinate plane whose axes are labeled x and y. Triangle A B C has vertex A at 1 comma negative 1, vertex B at 4 comma negative 2, and vertex C at 7 comma 2. Triangle A prime B prime C prime has vertex A prime at negative 1 comma 1, vertex B prime at negative 4 comma 2, and vertex C prime at negative 7 comma negative 2. Triangle A double prime B double prime and C double prime has vertex A double prime at negative 1 comma negative 2, vertex B double prime at negative 4 comma negative 1, and vertex C double prime at negative 7 comma negative 5.
The answers that complete the statements of the series of transformations are;
- △ABC to △A′B′C′; because the △ABC has been rotated at angle of 180° about the origin.
- △A′B′C′ to △A′′B′′C′′; Because the △A′B′C′ has been shifted down by 3 units.
- All 3 transformations are rigid transformations
- All three transformations are congruent transformations.
The image showing triangles △ABC, △A′′B′′C′′, and △A′B′C′ is missing and so I have attached it.From the image attached, we see the following coordinates of the triangles;
Coordinates of △ABC; A(1, -1), B(4, -2), C(7, 2)
Coordinates of △A′B′C′; A'(-1, 1), B'(-4, 2), C'(-7, -2)
Coordinates of △A′′B′′C′′; A''(-1. -2), B''(-4, -1), C''(-7, -5)
Now, in transformation from △ABC to △A′B′C′, we see that the pattern of transformation is; (x, y) → (−x ,−y). This pattern where coordinates of x and y are transformed to the negative part of them denotes that there has been a rotation at angle of 180° about the origin.In transformation from △A′B′C′ to △A′′B′′C′′, we see that triangle shifted down because the y-coordinates have reduced by 3 units. Thus, we can say that the transformation was to shift △A′B′C′ down by 3 units.In each of the transformations, we can tell that regardless of the position of the triangle, the distances AB, BC and AC remain the same. Thus, the transformation is rigid. The transformations are also congruent because all their corresponding sides are equal.Read more at; https://brainly.com/question/11254677

Victor's solution to an equation is shown below. Which property of real numbers did Victor use for Step 3? A. Associative Property of Multiplication B. Addition Property of Equality C. Subtraction Property of Equality D. Commutative Property of Multiplication
Answer:
can't see the equation sorry
Answer:
Subtraction Property of Equality
Step-by-step explanation:
Victor solved this inequality as shown:
Given: 6+3(x+5) = 36
Step 1: 6+3x+15 = 36
Step 2: 3x+21= 36
Step 3: 3x = 15
Step 4: 3x=15
What property justifies the work between step 3, I'm guessing its this question if not message me.
from step 2 to 3 we must use Subtraction Property of Equality since
3x+21 = 36 must subtract 21 both sides
then u get 3x=15
