Answer:

12 heads

Step-by-step explanation:

if each monster has 47 legs, then there cant be more then 2 monsters because that would be too many legs...and there cant be just 1 monster....because that would leave (106 - 47) = 59 legs....and human legs wont add up to 59....

2 monsters = (2 * 47) = 94 legs........leaving (106 - 94) = 12 legs

each human has 2 legs.......so that means 12/2 = 6 humans.

so we have 2 monsters (each with 47 legs) + 6 humans (each with 2 legs) = 106 legs

so we have 2 monsters and 6 humans....each monster has 3 heads..and if we have 2 monsters, we have (3 * 2) = 6 heads...and if we have 6 humans, we have 6 heads.....so there is a total of 12 heads <====

Write an exponential function in the form y = abthat goes through points (0, 20)<br> and (2,180).
Andrej [43]

Answer:

y=20(6)^x

Step-by-step explanation:

the graph passes through the point (0,20) : when x=0  and  y=20  :

20= ab^0    so a=20 because : b^0 = 1

the graph passes through the point (3,4320) : when x=3.  and  y=4320  : 4320= ab^3  but : a=20   so : 4320 = 20b^3

so : b^3 = 4320/20 = 216...... 216 =  6^3

b^3 = 6^3

b=6

the function is : y=20(6)^x

PLEASE HELP ME ,THIS IS HARD ,AND I DON’T UNDERSTAND MATH..
Tasya [4]

Answer:

Step-by-step explanation:

divide y by x

in a table and coordinate pair, which is something like (0,4), x always comes first. So, in this table x is the time in seconds and y is the distance in meters. 120/4=30 meters per second. For the second part of the table, since we know what the slope is, or the constant rate of change, 30, we can multiply 30 by 25 which is 750. You can also use the equation y=mx, m is the slope, and x is a point on the coordinate pair. For example, in the second table, y=30(25). For the last part of the table, you can use the same equation. 270=30x. We try to get x alone so we do, 270 divided by 30 which is 9. So a cheetah runs at 270 meters per 9 seconds.

Given three consecutive odd integers, what is the greatest number if triple of the sum of thrice the third one and twice the fir
Nostrana [21]

Let n be the smallest of these integers. The other two are then n + 2 and n + 4.

"triple of the sum of thrice the third one and twice the first one is equal to 291" is a long-winded way of saying

3 (3 (n + 4) + 2n) = 291

Solve for n :

3 (3n + 12 + 2n) + 291

3 (5n + 12) = 291

15n + 36 = 291

15n = 255

n = 17

Then the greatest of the three integers is n + 4 = 21.
