7. Marcy is taking part in a summer movie club. She will
earn 3 points for each movie she attends throughout the
summer. Which equation represents the relationship
between y, the total points, and x the number of movies?
A y=3x
B. y = 3+x
C. x= 3y
D. x=y+3
Answer:
The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;
A y = 3·x
Step-by-step explanation:
The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie
The number of points she will earn for attending each movie = 3 points
The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;
y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write
[tex]y = \sum\limits_{i =1}^x 3 = 3 \times x[/tex]
Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.

PLZ HELP ASAP BRANILIEST!!!! Seven hundred people are gathered in a trapezoidal park with bases measuring 50 yards and 90 yards and a height of 50 yards.
Find the population density of the park.
The population density of the park is ______ people per square yard.
Find the population density if the bases and height are halved.
The population density of the park if the bases and height are halved is
________people per square yard.
Answer:
0.2, 0.8
Step-by-step explanation:
The area of the park is 0.5h(b1 + b2), where h is the height, b1 is the first base, and b2 is the other base.
Plug the values in:
Area = 0.5(50)(50+90) = 0.5(50)(140) = (50)(70) = 3500
Since 700 people are in the park, there is 700/3500 = 0.2 people per square yard.
If the bases and height are halved, the new area is:
Area = 0.5(25)(25+45) = (35)(25) = 875
The new population density is 700/875 = 0.8 people per square yard.

Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seatsFormula of nth term:
aₙ = a₁ + (n - 1)daₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9aₙ = 3n + 9Humphrey needs to mail a package. He weighs it at home as 20.2 ounces. When he gets to the post office, the clerk weighs it at 18.6 ounces. What is the percent error in the weight of the package, assuming that his home weight is the correct weight?
Answer:
7.92%
Step-by-step explanation:
Given the following
Weight of package at home = 20.2 ounces.
Weight of the package at the office = 18.6ounces
Decrement = 20.2 - 18.6
percentage error = decrement/wt at home * 100
percentage error = 1.6/20.2* 100
percentage error = 160/20.2
percentage error = 7.92
HEnce the percent error in the weight of the package is 7.92%

For what values of x is the trinomial 2x2−x+55 equal to the square of binomial x+5?
The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6
Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;
2x^2−x+55 = (x+5)^2
2x^2−x+55 = x^2 + 10x + 25
Collect the like terms;
2x^2-x^2-x-10x+55-25 = 0
x^2 - 11x + 30 = 0
Factorize the result
x^2 - 6x - 5x + 30 =0
x(x-6)-5(x-6) = 0
x-5 = 0 and x - 6 = 0
x = 5 and 6
Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Using the markings below, determine which of the following is the measure of angle 2
Answer:
4. 132°Step-by-step explanation:
Both the triangles on the left and right are isosceles
The top angle of the triangle on the left:
180° - 2*69° = 42°The top angle of the triangle on the right:
90° - 42° = 48°This is the same angle as supplementary with angle 2:
∠2 = 180° - 48° = 132°Correct choice is 4
Beth is a real estate agent. She earns 6.5% commission on each sale she makes. Last month she sold a house for
$225,000 and another for $195,000. What did Beth earn in commissions for the month?
Answer:
Beth earned $27,300 in commissions
Step-by-step explanation:
225,000 * 6.5% = 14,625
195,000 * 6.5% = 12,675
12,675 + 14,625 = 27,300
So, the answer is 27,300

The diagram shows a square ABCD
M is the midpoint of AB
N is the midpoint of AD
The area of the shaded triangle AMN is 8cm^2
Work out the area of triangle MCN
The area of the triangle, Δ AMN is 8 cm², so the area of the triangle, ΔMCN is 24 cm².
A triangle is one of the most basic geometric figures with 3 sides, 3 angles, and 3 vertices.
The area of a triangle is half of the product of the base and height.
Given that
ABCD is square and M and N are mid-points of lines AB and AD respectively.
Area of triangle, ΔAMN = 8 cm²
[tex]\dfrac{1}{2} \times AN \times AM = 8\\AN \times AM = 8 \times 2\\AN \times AM = 16[/tex] ...(i)
Since ABCD is square, therefore AB = AD.
Also, as M and N are mid-points of lines AB and AD, so
AN = AM.
Substitute AN = AM in equation (i),
[tex]AN \times AN = 16\\AN^2 = 16\\AN = \sqrt{16}\\AN = 4\ cm[/tex]
So,
AD = 2 × AN
= 2 × 4
= 8 cm
As ABCD is square,
AB = BC = CD = AD = 8 cm.
Area of the square ABCD = 8² = 64.
Since CD = BC, ND = MB, ∠D = ∠B.
Therefore by SAS property of similarity,
ΔCDN ≅ ΔCBM
Area of the triangle, ΔCDN = Area of the triangle, ΔCBM.
[tex]= \dfrac{1}{2} \times CB \times BM\\= \dfrac{1}{2} \times 8 \times 4\\\\= 16\ cm^2[/tex]
Area of the triangle, ΔCMN = Area of ABCD - Area of ΔAMN - Area of ΔCDN - Area of ΔCBM
Area of the triangle, ΔCMN = 64 - 8 - 16 - 16
= 24 cm²
Therefore, the area of ΔCMN is 24 cm².

One pint of chalkboard paint covers 60 square feet. What is the least number of pints needed to paint the walls of a room in the shape of a rectangular prism with a length of 15 feet a width of 13 feet and a height of 10 feet
Answer:
15.833 pints of chalkboard paint
Step-by-step explanation:
Surface area of a rectangular prism = 2(lw × hl × hw)
Where,
L = length = 15 feet
w = Width = 13 feet
h = height = 10 feet
Surface area of a rectangular prism = 2(lw + hl + hw)
= 2(15*13 + 10*15 + 10*13)
= 2(195 + 150 + 130)
= 2(475)
= 950 square feet
One pint of chalkboard paint covers 60 square feet
Least number of pints needed to paint the walls = 950 square feet / 60 square feet
= 15.833 pints of chalkboard paint
