Answer:

84

Step-by-step explanation:

here's a little lesson for you:

if any number has the decimal ≥ 0.5, you should round up. like for example, if the number was 83.5, it would still be 84 as a whole number rounded.

however, if any number has the decimal ≤ 0.4, then you should round downwards, meaning that if the number given was 83.4, the whole number rounded would be 83

What is the solution to the equation w+6=5w-10

docker41 [41]

Answer:

w = 4

Step-by-step explanation:

you would do this by re-arranging the equation

6 = 5w-10-w (move w to the other side)

6 = 4w-10 (because 5w-w = 4w)

6+10=4w (move 10 to the other side)

16 = 4w (add 6 and 10)

4 = w (divide both sides by 4)

16z+29z=pz-v solve for z

Margarita [4]

16z + 29z=pz - v

45z - pz = -v

z(45 - p) = -v

z = $\frac{-v}{(45 - p)}$

Tony and Manuel were trimming the branches of a tree. Tony was using an 18 ft ladder and Manuel was using a 24 ft ladder. Both l

REY [17]

Answer:

9.33 feet = 111.96 inches

Step-by-step explanation:

If we have similar triangles, the rate between matching sides is the same.

So the length of the smaller ladder (18 ft) over the length of the taller ladder (24 ft) is equal to the distance from the bottom of the smaller ladder to the tree (7 ft) over the distance from the bottom of the taller ladder to the tree (x ft):

18 / 7 = 24 / x

x = 7 * 24 / 18

x = 9.33 feet

To find this measure in inches, we just need to multiply by 12:

x = 9.33 * 12 = 111.96 inches

Plot the axis of symmetry and the vertex for this function: h(x) = (x − 5)2 − 7.

jeka94

Answer:

The vertex and the axis of symmetry in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola written in vertex form is equal to

$f(x)=a(x-h)^2+k$

where

a is the leading coefficient

(h,k) is the vertex of the parabola

and the equation of the axis of symmetry is equal to the x-coordinate of the vertex

$x=h$

In this problem

we have

$h(x)=(x-5)^2-7$

This is a vertical parabola written in vertex form open upward

The vertex is a minimum

where

the vertex is the point (5,-7)

the x-coordinate of the vertex is 5

the equation of the axis of symmetry is equal to

$x=5$

The graph in the attached figure
