Answer:

Linear, y=6x-21

Step-by-step explanation:

Graph the answer to get an idea of the shape: linear.

Use y=mx+b and m=y2-y1/x2-x1 to find formula

m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6

y=6x+b

9=6(5)+b

9-30=b=-21

y=6x-21

Answer:

84

Step-by-step explanation:

To complete the concrete highway with pavers 84 pavers are needed.

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

From the given information each Pavel has an area of 4.5 square feet.

And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,

= (21×18) sq feet.

= 378 sq feet.

Therefore, The number of pavers needed is,

= (378/4.5).

= 84 pavers.

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

Step-by-step explanation:

Answer:

AB=5.39 cm

BC=5 cm

CD=5.83 cm

DE=3.91 cm

A to E=20.13 cm

Step-by-step explanation:

DE^2=2.5^2+3^2

DE^2=6.25+9

DE^2=15.25

DE=3.91

CD^2=3^2+5^2

CD^2=9+25

CD^2=34

CD= 5.83

BC^2=4^2+3^2

BC^2=16+9

BC^2=25

BC=5

AB^2=5^2+2^2

AB^2=25+4

AB^2=29

AB=5.39

5.39+5+5.83+3.91=20.13

Answer:

D. 2019

Step-by-step explanation:

So I started by rewriting the function f(x)

1000 = 10^3 so

    f(x)=10^3 times 1.03^x

1.03 = 103/100 so

     f(x)= 10^3 times (103/100)^x

to raise a fraction to a power you just raise the numerator and denominator to that power so

      f(x)= 10^3 times 103^x/100^x

change it to exponential form with a base of 10

     f(x)=10^3 times 103^x/10^2x

then you can reduce it with the 10^3

     f(x)=103^x/10^2x-3

so now that thats in more of a standard form you can find the intersection of the two functions

which is at (9.012,1305.244)

x is the number of years after 2010, so they will be equal ~9 years after 2010, which is 2019.

Step-by-step explanation:

There are more adults than children so the ratios made have to depict this.

These ratios should add up to 16.

Three different ratios:

11 adults : 5 children

9 adults : 7 children

13 adults : 3 children

The above will all add up to 16 and show more adults than children.

The different ratios of adults to children that might be on the bus is;

14 : 2, 13 : 3, 12 : 4, 11 : 5, 10 : 6, 9 : 7

We are given;

The people on the bus consist of adults and children.

We are told that;

Thus, the different possibilities for ratio between

adults and children will be 2 numbers that add up to 16 which must not be equal. Thus, we have;

14 : 2

13 : 3
