Answer: 22y and 9y+13y

Step-by-step explanation: Just using basic math, ofc

1st Answer: 9y + 9y = 18y .

18y + 4y = 22y

2nd Answer: 9y + 10y = 19y .

19y + 3y = 22y

Students are painting a mural. So far the mural is painted 1/4 blue 2/8 red and 3/12 green. Use fraction strips to determine how

nirvana33 [79]

If you make the denominators all the same, the fractions are 3/12 , 3/12 , and 3/12. Then by simply adding them together you get that the mural is 9/12 painted. that then simplifies to 3/4 or 75%

Hope this helps :)

A rocket is launched from a tower. The height of the rocket , y in feet, is related to the time after launch, x in seconds, by t

Nikolay [14]

<h3>Answer: Max height = 455.6 feet</h3>

========================================================

Explanation:

The general equation

y = ax^2 + bx + c

has the vertex (h,k) such that

h = -b/(2a)

In this case, a = -16 and b = 147. This means,

h = -b/(2a)

h = -147/(2*(-16))

h = 4.59375

The x coordinate of the vertex is x = 4.59375

Plug this into the original equation to find the y coordinate of the vertex.

y = -16x^2+147x+118

y = -16(4.59375)^2+147(4.59375)+118

y = 455.640625

The vertex is located at (h,k) = (4.59375, 455.640625)

The max height of the rocket occurs at the vertex point. Therefore, the max height is y = 455.640625 feet which rounds to y = 455.6 feet

1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is th

Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

$I=Prt$

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

$I=Pr(3)\\$

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

$I=\frac{Pr(4)}{12}$

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

$I=\frac{Pr(45)}{365}$

Which point can be used to find f(3)

Andreas93 [3]

Commonly the horizontal axis represent the x-axis. So, you need the point that means x = 3 (positive 3), so, it is the point A.
