Answer:
5.02 pounds
Step-by-step explanation:
y = k*x
Where,
y = weight of a object on Jupiter
x = weight of the object on earth
k = constant of proportionality
An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.
y = k*x
378.2 = k*150
378.2 = 150k
k = 378.2/150
= 2.5213
Approximately k = 2.52
determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth
y = k*x
12.64 = 2.52*x
12.64 = 2.52x
x = 12.64 / 2.52
= 5.0159
Approximately x = 5.02 pounds
Answer:
55%
Step-by-step explanation:
11/20 =
11 ÷ 20 =
0.55 =
0.55 × 100/100 =
0.55 × 100% =
The given measurement of the Instagram photo is "4" by "4". And a poster enlargement is being printed with a scale factor of 8.5 .
So on using the scale factor of 8.5 , lengths of new sides are "8.5 *4" by "8.5 *4"
= " 34" by "34" .
So the new lengths of the enlarged pictures are of dimension "34" by "34" .
Answers:
22.)D
23.)D
How?
Explaining number 22:
Well, let’s disprove each one of them.
A.) A is saying 6x=7. Even if we simplify that, it wouldn’t make any sense in what we are trying to do. That equation is equal to x=0.86(estimated to nearest tenth)
B.) B says that 6x=3. When we simplify this, we get x=0.5. That isn’t the number we want, so we know B isn’t right
C.) C is equivalent to 2x+2=6. Let’s simplify since it is multi-step.
2x+2=6
2x=6
x=3
Since we want x to be six, this wouldn’t be the answer either.
D.) D is saying 2x=12. When simplified, this becomes x=6. BINGO THERE IS OUR ANSWER
Explaining 23:
For this, I also used process of elimination.
Remember that x is equal to 2.5
A.)
x+3=5.5
2.5+3=5.5
5.5=5.5
That works.
B.)
2x=5
2(2.5)=5
5=5
That works.
C.)
2.5/2=1.25
1.25=1.25
That works
D.)
x-10=7.5
2.5-10=7.5
-7.5=7.5
THAT DOESNT WORK THERE IS OUR ANSWER
If you divide 6 by 8= 0.75, which is equivalent to 75%. So Amber made 75% of her free throws.
