Answer:

4 7/10

Step-by-step explanation:

2 3/5 = 2 6/10

2 6/10 - 5/10 = 2 1/10

2 6/10 + 2 1/10 = 4 7/10

What is this I'm lost

Ghella [55]

Basically you have to convert the equalities in each box.
I'll help you figure out what the equalities are and hopefully you can figure it out from there.

Milli= .001
Centi= .01
Deci= .1
Unit base=1
Deka= 10
Hecto= 100
Kilo= 1000

In the first box, it asks for you to convert a millimeter into a meter

1mm=.001m

If you have any more trouble, please message me. I'd be happy to help

2. through: (8,5), perpendicular to y=-1/2x +4

SCORPION-xisa [38]

Perpendicular slope: flip sign and reciprocal = 2
Y = 2x + b
Plug in point (8,5)
5 = 2(8) + b
5 = 16 + b
b = -11
Equation: y= 2x - 11

Answer:

-0.16

Step-by-step explanation:

The 'a' value can be found by looking at the difference between the y-value of a point 1 unit from the vertex, and the y-value of the vertex.

Here, that is a negative fraction of a unit. If we assume the value is a rational number that can be accurately determined from this graph, then we can find it by looking for a point where the graph crosses a grid intersection. It looks like such grid points are (-7, 0) and (3, 0). The vertex is apparently (-2, 4), so the vertex form of the equation is ...

y = a(x +2)^2 +4

Using the point (3, 0), we have ...

0 = a(3 +2)^2 +4 . . . . . fill in the values of x and y

-4 = 25a . . . . . . . . . . subtract 4; next, divide by 25

a = -4/25 = -0.16

Use the given scale factor in the side length of the scale drawing to determine the side links of the real object

ozzi

Answer:

A. side a is 7 inches long, side b is 6 inches long,and side c is 3 inches long

Step-by-step explanation:

Here is the complete question. Please find attached a diagram showing the scaled and real drawing

Use the given scale factor and the side lengths of the scale drawing to determine the side lengths of the real object

A. side a is 7 inches long, side b is 6 inches long,and side c is 3 inches long

B. side a is 30 inches long, side b is 25 inches long, and side c is 20 inches long

C. side a is 40 inches long, side b is 35 inches long,and side c is 20 inches long

D. side a is 175 inches long,side b is 150 inches long, and side c is inches long

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

The scaled drawing is an enlarged image of the original triangle.

It is enlarged at a ratio of 5:1

original dimensions

a = 35/5 = 7

b = 30 / 5 = 6

c = 15/5 = 3
