Answer:
The answer to your question is 24 cm³
Step-by-step explanation:
Data
Initial volume = 2/5
Additional volume = 42 cm³
Final volume = 4/7
the total volume of the glass = ?
Process
1.- Write a proportion to help you solve the problem
42 cm³ -------------------- 4/7 of the total
x ------------------- 7/7
2.- Solve the proportion
x = (7/7 x 42) / 4/7
3.- Simplification
x = 42 / 4/7
x = 168/7
x = 24 cm³
Answer:
24 birds
Step-by-step explanation:
Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...
5b +7.5(41 -b) = 247.50
-2.5b +307.50 = 247.50 . . . . . simplify
-2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50
b = 24 . . . . . . . . . divide by -2.5
The number of birds at the shelter on Wednesday was 24.
The answer is 7x = 6(x + 15)
x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours: 7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y
</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15
</span>7x = 6y
y = x + 15
Substitute the second equation into the first one:
7x = 6(x + 15)
Answer: 5.64 *10^2
Step-by-step explanation:
A rhombus is related to a “Parallelogram”
Why? - because it fulfills the requirements of a parallelogram: a quadrilateral with two pairs of parallel sides. It goes above and beyond that to also have four equal-length sides, but it is still a type of parallelogram.
hope this helped <3
