Answer: A
Step-by-step explanation: If you fill in the x-intercept and the y-intercept and solve -4(2) + 20 = 12 And -4(3) + 20 = 8
if you solve for those you would get your y-intercept

James paid 13.20 for 12 mangoes. For every 5 mangoes that he bought he got one mango free. Mary wants to by 4 mangoes from the same shop. She only has $5.10. How much more money does she need
Answers
Answer:
Mary needs $0.18 more
Step-by-step explanation:
12 mangoes = $13.20
For every 5 mangoes that he bought he got one mango free
This means he bought 10 mangoes (5 mangoes + 1 free mango the first time and 5 mangoes + 1 free mango the second time)
If James paid $13.20 for 10 mangoes, then
Each mango cost = $13.20 / 10
= $1.32
Each mango cost $1.32
Mary wants to by 4 mangoes from the same shop.
Total cost of 4 mangoes = $1.32 × 4
= $5.28
She only has $5.10.
How much more money does she need
Amount needed more = Total amount required - total amount available
= $5.28 - $5.10
= $0.18
Mary needs $0.18 more

Zack wants to purchase vinyl to go on his bathroom floor. The vinyl is sold by the foot in length. If the area of his bathroom is 100 square feet, what will one side of the square bathroom measure?
Answers
Answer:
x = 10 feet
Step-by-step explanation:
Given that,
The area of his bathroom is 100 square feet.
We need to find the one side of the square bathroom.
Let the side be x. The area of a square is given by :
[tex]A=x^2\\\\100=x^2\\\\x=10\ \text{feet}[/tex]
So, the side of the square bathroom is 10 feet.

In the lower triangle, one of the angles of which is 45 degrees, we know:
In the triangle, the side facing the angle 45° is √2 / 2 times the hypothenuse.
Thus ;
[tex]10 = hypothenuse \times \frac{ \sqrt{2} }{2} \\ [/tex]
[tex]hypothenuse \times \frac{ \sqrt{2} }{2} = 10 \\ [/tex]
Multiply sides by 2
[tex]hypothenuse \times \sqrt{2} = 2 \times 10[/tex]
Divide sides by √2
[tex]hypothenuse = \frac{2 \times 10}{ \sqrt{2} } \\ [/tex]
[tex]hypothenuse = \frac{ \sqrt{2} \times \sqrt{2} \times 10 }{ \sqrt{2} } \\ [/tex]
[tex]hypothenuse = 10 \sqrt{2} [/tex]

The common side of the triangles is hypothenuse for both.

[tex]10 \sqrt{2} \times \frac{1}{2} = x \\ [/tex]

Answers
Esta pregunta esta incompleta
Pregunta completa
Calcula el número de vueltas por minuto que hace la polea pequeña mientras que la grande hace 40 vueltas. Sabiendo que cada polea gira de manera que el radio y el número de vueltas son inversamente proporcionales.
El radio de la polea pequeña = 3 cm.
El radio de la polea grande = 9 cm
Answer:
120 vueltas por minuto
Step-by-step explanation:
El radio y el número de vueltas son inversamente proporcionales.
Por lo tanto
R = Radio
T = El número de vueltas por minuto
R ∝ 1 / T
R = k / T
Donde k es constante de proporcionalidad
Polea grande
R = 9 cm
T = 40 vueltas
9 = k / 40
k = 9 × 40
k = 360
Debemos encontrar el número de vueltas para la polea pequeña, por lo tanto,
R = k / T
k = 360, R = 3 cm
3 = 360 / T
3 × T = 360
T = 360/3
T = 120 vueltas
El número de vueltas de la polea pequeña = 120 vueltas por minuto

Add 6 to each side
-1/3 y -6+6 = -11+6
-1/3 y = -5
Multiply each side by -3
-1/3 y * -3 = -5*-3
y = 15
Check
-1/3 *15 -6 = -11
-5 -6 = -11
-11=-11
The area of a circle, in terms of π, is 196π m2.
Find the value of the radius.
Answers
Step-by-step explanation:
if area of circle = pi times radius^2,
area of circle divided by pi = radius^2
so, square root (area of circle divided by 2) = radius.
so, 196pi = m2
approx 616
616=m2
sqrt 616 =m
approx value of radius is 25 or 24.8

Answer:
3948 members
Step-by-step explanation:
SInce a is the initial amount, a = 2000. b represents growth factor, and the amount increases by 12% every year, so b = 1.12. Since you want to find the value in 6 years, x= 6. Therefore your equation is y = 2000 • 1.12 ^ 6. Plug it into your calculator and you get y = 3947.64, and since they are people you round up to 3948 members.

Answers
Answer:
[tex]\dfrac{27}{100}[/tex]
Step-by-step explanation:
The number [tex]0.27[/tex] can be attained by the following expression
[tex]0.27=\dfrac{k27}{k100}[/tex]
Where
[tex]k[/tex] = any positive positive integer.
Let us take the minimum ratio
[tex]0.27=\dfrac{1\times 27}{1\times 100}[/tex]
[tex]=\dfrac{27}{100}[/tex]
where [tex]k = 1[/tex]
So, the probability estimate in ratio form is [tex]\dfrac{27}{100}[/tex].
