Answer: the answer is D. the spread is from 1 to 6.
Step-by-step explanation:
Answer:
2(W - 5) ≤ -29
Step-by-step explanation:
"Twice the difference of a number and 5 is at most -29" can be expressed symbolically as follows:
2(W - 5) ≤ -29
Further explanations:
"the difference of a number and 5" is W - 5, and thus "Twice the difference of a number and 5" is 2(W - 5).
"x ≤ -29" states "x is at most -29."
The stalactites become 0.004 + 0.006 = 0.01 inches closer each year, and begin 10 feet apart, or 120 inches apart.
let y be the distance between them, and x be the number of years that go by:
y = -0.01x + 120
We want to find where y = 0, where they meet:
0 = -0.01x + 120 Add 0.01x to both sides
0.01x = 120 Multiply both sides by 100
x = 12,000
The stalagmite and stalactite will meet in 12,000 years
Under a dilation, triangle XYZ where X(4, 7), Y(-3, 8), and Z(-2, -1) becomes triangle X’Y’Z’ where X’(12, 21), Y’(-9, 24), and
-BARSIC- [3]
It is 3, the points are all 3 times greater
Answer:
a
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
let x be the other leg to be found, then
155² = 124² + x²
24025 = 15376 + x² ( subtract 15376 from both sides )
8649 = x² ( take the square root of both sides )
= x
Hence x = 93 cm ← length of other leg → a
