Answer:
It's D
Step-by-step explanation:
2t - 30() = 20
2t - () = 20
2t - = 20
2t - 6 = 20
2t - 6 + 6 = 20 +6
2t = 26
=
t = 13
Answer:
Step-by-step explanation:
Jim drank 2 and 4/5 orange juice
2and 4/5=14/5 orange juice
jack drank 1and 1/10 less than Jim= 11/10 less than Jim
I introduce the whole numbers into the fractions
we will convert the number 14/5 into a fraction that has the denominator 10, by multiplying by 2 both numerator and denominator
(14/5 )*2=28/10
Now we can find out how much juine Jack drank
28/10- 11/10= 17/10
so Jack drank 17/10 orange juice , the fraction can be written also as
1 and 7/10
Answer:
Perimeter is 130r units
Area is n*r^2 square units
Step-by-step explanation:
So, something special happens to perimeter and area if you scale a figure by some factor. let's say you make a figure twice as big, well, the perimeter also gets twice as big. Area though will get 4 times as big. more generally, if you scale a figure by x, the perimeter also scales by x, while the area scales by x^2.
So for this triangle, the perimeter of abc is 30 + 40 + 60, then when you scale them by r the perimeter becomes 30r + 40r + 60r or (30 + 40 +60)r. of course 30 + 60 + 40 is 130 so the perimeter of xyz is 130r
Now for area, the problem just vices us the area as n. Scaling the sides by r makes the area n*r^2. This is for all shapes. If you want to check try on a random triangle, or more easily a square
For this case we have the following statement:
<em>"You have 2 meters of fabric and you cut 85% to make curtains, 50% of the rest to make the strips that hold it. How many centimeters of fabric were left?"</em>
So, we have:
2 meters ---------> 100%
x ----------------------> 85%
Where "x" represents the amount of fabric meters equivalent to 85%.
Thus, 1.7 meters of fabric were used to make curtains.
There are 0.3 meters of fabric left, of which half (50%) is used to make the strips that hold the curtain. That is to say:
Thus, 0.15 meters of fabric remain.
Thus, 15 cm of fabric remain
Answer;
15 cm
