We know that 4 and below rounds down and 5 and above round up

That means she walked 3.5 miles   her sister walked 1.2 miles

and her brother walked 0.9 miles

1.2+0.9=2.1 

3.5-2.1=1.4

Lee and Maya are collecting leaves for an art project lee collects 25/100 of the total number leaves needed. Maya collects 4/10
MrRissso [65]

Answer:  The answer is \dfrac{13}{20}.


Step-by-step explanation:  Given that Lee and Maya are collecting leaves for an art project. Let'x' be the total number of leaves needed in the project.

Then, the number of leaves collected by Lee is given by

L_\ell=\dfrac{25}{100}x,

and the fraction of the leaves collected by Maya is given by

M_\ell=\dfrac{4}{10}x.

Therefore, the total number of leaves collected by Lee and Maya altogether is

L=L_\ell+M_\ell=\dfrac{25}{100}x+\dfrac{4}{10}x=\dfrac{25+40}{100}x=\dfrac{65}{100}x=\dfrac{13}{20}x.

Thus, the total fraction of the leaves collected by Lee and Maya is

\dfrac{13}{20}.

Equation of the parabola in vertex form that passes through (4,-7) and has a vertex of (1,-6)
Alina [70]

y = -\frac{1}{9}(x - 1)^2 - 6

Step-by-step explanation:

The vertex form of the equation for a parabola is given by

y = a(x - h)^2 + k

where (h, k) are the coordinates of the parabola's vertex. Since the vertex is at (1, -6), we can write the equation as

y = a(x - 1)^2 - 6

Also, since the parabola passes through (4, -7), we can use this to find the value for a:

-7 = a(4 - 1)^2 - 6 \Rightarrow -7 = 9a - 6

or

a = -\frac{1}{9}

Therefore, the equation of the parabola is

y = -\frac{1}{9}(x - 1)^2 - 6
