Answer:

7. 48000 ounces

8. 1. 25 pound

9. 1/16

10. ounces

11. weight

12. pounds

Step-by-step explanation:

7) A hippopotamus weighs 1. 5 tons. What is its weighs in ounces

answer

All you need to do is to use proportion to solve this problem

Let x represent the weight of the hippopotamus in ounces

1 ton = 32 000 ounces

1. 5tons= x

cross multiply to get the value of x

x = 32000 × 1. 5

x = 48 000 ounces

Therefore the weight of the hippopotamus in ounces is 48 000

9. What fractional part of a pound is an ounce

answer

1 pound = 16 ounces

which implies

1 ounce = 1/16 pounds

Therefore the fractional part of a pound that is an ounce is 1/16

10. Since the weight of a paper is very light, ounce woud be the most appropriate customary unit to measure it

11. Weight is the measure of how heavy an object is.

12. The weight of a bag of a flour is not upto a ton, therefore pounds would be the appropriate customary unit to measure the weight of a flour.

Find the equation of the line shown. y 4 3 2 1 Х -2 -3 4​
MakcuM [25]

Answer:

y = 1/2x + 0.5

or

y = 1/2x + 1/2

Step-by-step explanation:

y = mx + b

b is y-intercept:

when x = 0, y = 0.5 (when the line cross the vertical (y) axis of the graph)

the point is (0, 0.5) so b = 0.5

m is slope:

slope = rise / run

rise = 1

run = 2

for every 2 x values, y increase by 1

slope (m) = 1/2

EastWind [94]

Answer:

Let coordinates of vertex D be (x,y)

In parallelogram diagonals are bisect each other.

∴ Mid-point of AC= Mid-point of BD

⇒ (

2

3+(−6)

,

2

−4+2

)=(

2

−1+x

,

2

−3+y

)

⇒ (

2

−3

,

2

−2

)=(

2

−1+x

,

2

−3+y

)

⇒ (

2

−3

,−1)=(

2

−1+x

,

2

−3+y

)

Now,

⇒

2

−3

=

2

−1+x

⇒ −6=−2+2x

⇒ −4=2x

∴ x=−2

⇒ −1=

2

−3+y

⇒ −2=−3+y

⇒ 1=y

∴ y=1

∴ Coordinates of vertex D is (−2,1)

Mary walks 4 miles north and then turns and walks 5 miles west. How far is she from her original starting point?
dusya [7]
Answer:  6.403 miles; or, write as:  6.403 mi.  .
__________________________________________________
Explanation:
_________________________________________________





                                5
--------------------------------------------
`                             right angle   |_ |
   `          (right triangle )                 |
         `                                               |    4 
             `                                           |
                      `    
       "c"                        `                  \        
 (hypotenuse)                          Starting point
                     
__________________________________________________
Since we have a "right triangle, we solve for "c"; using the 
"Pythagorean theorem" ; 
_______________________________________________________
→  a² + b² = c² ; Solve for "c" ; our answer (in "miles"; or, "mi.") ;
__________________________________________________
Given : a = 4; b = 5 ; 
____________________________
Plug these known values into our equation:
________________________________________
 → 4² + 5² = c² ; 
____________________________
 → 16 + 25 = c² ;  ↔  c² = 16 + 25 ;
______________________________
 → c² = 41 ; 
_______________________________
 → Take the positive square root of each side of the equation (since the side of a "triangle" cannot be "negative"; 
__________________________________
 → √(c²) = √(41) ; 
_____________________________
 → c =  √41 ; Use calculator;
________________________________
 → c =  6.40312423743 ; Round to:  

 → c = 6.403 miles; or, 6.403 mi.
