A chain has 47 links. 13 link from one end is rusted. From the other end 17 link is also rusted. How many links lie between these tw rusted links?
Answer:
17
Step-by-step explanation:
Answer:
17 links
Step-by-step explanation:
1. 13 Links and 17 links are rusted. Since we need to find out the number of links that are not rusted, we need to add 13+17.
a. 13 + 17 = 30
2. Now since we added the number of lines rusted, we now should subtract the ones rusted and the one not rusted to get the answer.
a. 47-30 = 17
FINAL ANSWER: 17

write 0.00000000018 in a scientific notation
Answer:
[tex]1.8*10^{-10}[/tex]
Step-by-step explanation:
To find the number in scientific notation you want to find how many times you have to move the decimal to get the decimal to be right after the first non-zero number. If you move to the left the exponent is positive and if you move it to the right the exponent is negative. The answer would be [tex]1.8*10^{-10}[/tex].

Twelve hundred dollars ($1200) is divided among four sisters so that each gets $100 more than her next-youngest sister. How much will the two middle sisters each receive?
Answer:
The two middle sisters will each receive $250 and $350 respectively
Step-by-step explanation:
Let
The 4th sister = x
The 3rd sister = 100 + x
The second sister = 200 + x
The first sister = 300 + x
Total amount to share = $1,200
x + (x + 100) + (x + 200) + (x + 300) = 1,200
x + x + 100 + x + 200 + x + 300 = 1,200
4x + 600 = 1,200
4x = 1,200 - 600
4x = 600
Divide both sides by 4
x = 600/4
= 150
x = $150
There two middle sisters are:
The 3rd sister = 100 + x
= 100 + 150
= $250
The second sister = 200 + x
= 200 + 150
= $350
The two middle sisters will each receive $250 and $350 respectively
The 4th sister = x = $150
The first sister = 300 + x
= 300 + 150
= $450

If j and k are nonzero integers, which pair of points must lie in the same quadrant?
(j, j) and (k, k)
(j, k) and (jk, jk)
(j + k, 3) and (3, j + k)
(3j, 3k) and (StartFraction 3 Over j EndFraction, StartFraction 3 Over k EndFraction)
The slash indicates a fraction.
=============================================
Proof:
We'll need to consider 4 different cases.
-----------------------
Case (1): j > 0 and k > 0
If j > 0, then 3j > 0 and 3/j > 0
If k > 0, then 3k > 0 and 3/k > 0
The two points (3j, 3k) and (3/j, 3/k) are both in quadrant 1.
-----------------------
Case (2): j > 0 and k < 0
If j > 0, then 3j > 0 and 3/j > 0
If k < 0, then 3k < 0 and 3/k < 0
Points (3j, 3k) and (3/j, 3/k) are both in quadrant 4.
------------------------
Case (3): j < 0 and k > 0
If j < 0, then 3j < 0 and 3/j < 0
If k > 0, then 3k > 0 and 3/k > 0
Points (3j, 3k) and (3/j, 3/k) are in quadrant 3.
------------------------
Case (4): j < 0 and k < 0
If j < 0, then 3j < 0 and 3/j < 0
If k < 0, then 3k < 0 and 3/k < 0
Points (3j, 3k) and (3/j, 3/k) are in quadrant 4.
------------------------
For nonzero integers j and k, we've shown that Points (3j, 3k) and (3/j, 3/k) are in the same quadrant. This concludes the proof.

Answer:
x = 7, arc DE = 198°
Step-by-step explanation:
Inscribed angles from the same arc are congruent.
∠ DCE and ∠ DWE are inscribed angles from the same arc DE , thus
12x + 15 = 3x + 78 ( subtract 3x from both sides )
9x + 15 = 78 ( subtract 15 from both sides )
9x = 63 ( divide both sides by 9 )
x = 7
Thus
∠ DCE = 12x + 15 = 12(7) + 15 = 84 + 15 = 99°
The inscribed angle DCE is half the measure of its intercepted arc, thus
arc DE = 2 × 99° = 198°
A carpenter use 65 shelves to make 13 bookcases. She uses the same number of shelves for each bookcase. Are 32 shelves enough to build 6 more bookcases?
Answer:
Yes.
Step-by-step explanation:
First, find the unit rate for 1 bookcase.
65 ÷ by 13 = 5 (unit rate)
Then, multiply the unit rate by the bookcases the carpenter wants to make.
6 · 5 = 30
Finally, subtract the shelves the carpenter wants to use by 30.
32 - 30 = 2 shelves.
Therefore, 32 shelves is enough to build 6 more bookcases. <3

Answer:
GH = 12, JH = 8, GJ = 10.6, your answer is the first choice
Step-by-step explanation:
Mid-segment theorem basically means it's like cut in half so just apply that logic to the entire thing:
DG = GF and IH = HF
DI length, 24, divided by two, because half, equals 12 so 12 = GH
JH is DF divided by two so basically 16/2 which is 8 which also equals DG
GJ = IH because like I said half half theory
Essentially, all the parallel lines are halves of each other.
GH = 12, JH = 8, GJ = 10.6, your answer is the first choice
Let p(x) = -2x - 9. If p(x) = -19, find x.
Answer:
x=5
Step-by-step explanation:
Step 1: Flip the equation.
−2x−9=−19
Step 2: Add 9 to both sides.
−2x−9+9=−19+9
−2x=−10
Step 3: Divide both sides by -2.
Exact Form:
x = 9/17
Decimal Form:
x = 0.52941176…
Edit: "but what are the steps to get 9/17"
1. Move all terms containing x to the left side of the equation.
2. Divide each term by −17 and simplify.
The graph of a linear function “f” passes through the point (1, 3) and has a slope of 3.
What is the y-intercept?
Answer:
0
Step-by-step explanation:
Using slope intercept as ref (y=mx+b)
plug in the x and y x=1 and y=3 and the slope m=3
3=3(1)+b
solve for b
3=3+b
b=0
On a coordinate plane, a straight line with a positive slope begins at point (0, 50) and ends at point (5.5, 600).
Which scenario is most likely the one shown on the graph?

3.)the total weight of the barbell, y, where the bar weighs 50 pounds and x 100-pound weights are added to it
4.) the total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce

Answer:
32, consecutive interior angles are supplementary.
Step-by-step explanation:
We know that the two angles add up to 180, because consecutive interior angles are supplementary. So let's set up an equation equal to 180.
2x + 3x + 20 = 180
Now let's add like terms.
5x + 20 = 180
Now let's subtract 20 from both sides.
5x = 160
Now let's divide both sides by 5.
x = 32

if u subtract 17 from my number and multiply the difference by -5 the result is -25 what is the number
Answer:
the number is 22
Step-by-step explanation:
let the number be x
-5(x-17) = -25
-5x + 85 = - 25
-5x = - 25 - 85
-5x = - 110
x = - 110 ÷ - 5
x = 22
Check answer
- 5 × ( 22) + 85
- 110 + 85
- 25

what is this^
a)rectangular prism
b)pentagonal prism
c)rectangular pyramid
d)hexagonal prism
Answer:
A) rectangular prism
Explanation:
The base is a rectangle, not a pentagon nor hexagon. So B and D are out.
The difference between a prism and a pyramid is the shape.
Prism just tends to be extensions of the base while the pyramid would have a pointy top, just like a pyramid.
There is no pointy top on the object, so it is a rectangular prism.
