The movie club is having a new member sale, so Mindy signs up. The equation -0.4x + 0.05y - 1.25 = 0 relates y, the total cost, and x, the number of months. What is the y-intercept of the line represented by the equation?
Answers
Answer:
Y intercept : ( 0 , 25 )
Step-by-step explanation:
Answer:
(0, 25)Step-by-step explanation:
We need to convert function to slope-intrcept form y=mx+b, where:
-0.4x + 0.05y - 1.25 = 0 {multiply both sides by 20}
-8x + y - 25 = 0 {add (8x+25) to both sides}
y = 8x + 25 ⇒ b = 25
Therefore y-intercept of the line is (0, 25)

The triangle shown below are similar. Solve for x. 
Answers
Answer:
x=16
Step-by-step explanation:
27/45=(2x+7)/(4x+1)
cross multiply
27(4x+1)=45(2x+7)
108x+27=90x+315
108x-90x=315-27
18x=288
x=288/18
x=16
Looking at the image, The triangle shown below are similar. The value for x is 16.
What is the triangle about?Note that in the triangle given, the shapes are similar. Therefore:
27/45 = 2x + 7/ 4x + 1
3/5 = 2x + 7/ 4x + 1
So:
3 (4x + 1) = 5 (2x + 7)
12x + 3 = 10x + 35
12x - 10x = 35-3
2x = 32
x = 32/ 2
x = 16
Therefore, the value of x is 16.

Answers
Answer:
[tex]x = \frac{ - 63}{2} \: or \: - 31.5[/tex]
Step-by-step explanation:
[tex] \frac{x}{7} - \frac{x}{9} = - 1[/tex]
Lets take the L.C.M of 7 & 9.
L.C.M of 7 & 9 = 63
[tex] = > \frac{9x - 7x}{63} = - 1[/tex]
[tex] = > \frac{2x}{ 63} = - 1[/tex]

The population of a city decreases by 1.6% per year. If this year's population is 320,000, what will next year's population be, to the nearest individual?
Answers
Answer:
314,880
Step-by-step explanation:
If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

Answer:
5/12
Step-by-step explanation:
Since Pedro had 1/3 of the book remaining at the end of the day, he had read a total of 2/3 of the book. If n represents the amount read at night, you have ...
1/4 + n = 2/3
3 +12n = 8 . . . . . multiply by 12
12n = 5 . . . . . . . .subtract 3
n = 5/12 . . . . . . divide by 12
Pedro read 5/12 of the book at night.
_____
Since Pedro reads only a fraction of the book, it is not a "mixed number."
__
The solution is equivalent to finding the difference ...
2/3 - 1/4
= 8/12 - 3/12 = 5/12

Mrs. Cho is bringing cans and bottles to a recycling center. For a type A can, she gets 5 cents. For type B can, she gets 10 cents. She knows that she has redeemed at least 11 cans but has no more than 95cents. What are the possible combinations?
Answers
Answer:
One possible solution be -
Mrs. Cho is brings type A cans = 10
Mrs. Cho is brings type B cans = 3
Step-by-step explanation:
Let us assume
Mrs. Cho is brings type A cans = x
Mrs. Cho is brings type B cans = y
As given,
For a type A can, she gets 5 cents and For type B can, she gets 10 cents
As we have x Type A cans and y Type B cans
And she has redeemed no more than 95 cents
⇒5x + 10y ≤ 95 .......(1)
Also given,
She has redeemed at least 11 cans
⇒ x + y ≥ 11 ........(2)
∴ we get
x + y ≥ 11
5x + 10y ≤ 95
By applying graphical method , we get
The equations become
5x + 10y = 95 .......(1)
x + y = 11 ........(2)
Table for equation (1) -
x y
0 9.5
19 0
Table for equation (2) -
x y
0 11
11 0
The two lines intersect at point (3, 8)
So the possible combinations are in the shaded portion which is covered by both the lines.
One possible combination is ( 10, 3) which lies in the shaded region.
So,
Mrs. Cho is brings type A cans = x = 10
Mrs. Cho is brings type B cans = y = 3

Each circles radius diameter circumference and formula used needs to be found!!!! I need help urgently and I’ll give brainliest!
Answers
Answer:
Check bolded below
Step-by-step explanation:
1)radius = 10 in (given), diameter = 2*radius = 2(10 in) = 20 in
formula for circumference => 2πr => 2π(10)
circumference = 20π in
2)diameter = 12 ft (given), radius = 1/2*diameter = 1/2(12 ft) = 6 ft
formula for circumference => 2πr => 2π(6)
circumference = 12π ft
3)radius = 3 m (given), diameter = 2*radius = 2(3 m) = 6 m
formula for circumference => 2πr => 2π(3)
circumference = 6π m
4)diameter = 18 cm (given), radius = 1/2*diameter = 1/2(18 cm) = 9 cm
formula for circumference => 2πr => 2π(9)
circumference = 18π cm
1.
radius = 10 in
diameter = 10 × 2 = 20 in
formula = π × d
circumference = π × 20 = 62.83 in
2.
radius = 12 ÷ 2 = 6 ft
diameter = 12 ft
formula = π × d
circumference = π × 12 = 37.70 ft
3.
radius = 3 m
diameter = 3 × 2 = 6 m
formula = π × d
circumference = π × 6 = 18.85 m
4.
radius = 18 ÷ 2 = 9 cm
diameter = 18 cm
formula = π × d
circumference = π × 18 = 56.55 cm

Answer:
437.3 ftStep-by-step explanation:

sin A = perpendicular ÷ hypotenuse
