Tony need 16 inch long pieces of gold chain to make each 3 necklaces. He has a peice of chain that is 4 1/2 long. How much chain will he have left after making the necklaces
Answer: 6 inches of chain will he have left after making the necklaces
Step-by-step explanation:
There is a missing information. The correct question is:
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces.
Solution
We would convert 4.5 feet to inches
1 foot = 12 inches
4.5 feet = 4.5 × 12 = 54 inches
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. It means that the number of the 16 inches pieces of gold chain that can be gotten to make each of 3 necklaces necklaces is 16 × 3 = 48
The length of chain left chain that will he have left after making the necklaces is
54 - 48 = 6 inches

Leslie found the volume of a cone having both a height and diameter of 12 inches. Her work is shown below.
(attached)
Analyze Leslie’s work. Is she correct? If not, what was her mistake?
Yes, she is correct.
No, the radius is twice the diameter, so she needed to multiply by two instead of dividing.
No, the value of 62 is 6 times 2, or 12.
No, she forgot to take one-third of the base area times height.

Juliet is standing on the balcony 44 above the ground. She is looking at Romeo at an angle of depression of 6 degrees. if both star-crossed lovers were holding the end of a strong, what would the length of the string be?
Answer:
length of string ≈ 421 units (nearest whole number)
Step-by-step explanation:
Juliet is standing on the balcony 44 above the ground . The angle of depression is 6°. A string was held between Juliet and Romeo.
The illustration forms a right angle triangle. The hypotenuse of the triangle is the length of the string held by both star crossed lovers. The opposite side of the triangle is given as 44. Therefore,
using sin ratio
sin 6° = opposite/hypotenuse
sin 6° = 44/length of string
cross multiply
length of string sin 6° = 44
divide both sides by sin 6°
length of string = 44/sin 6°
length of string = 44/0.10452846326
length of string = 420.937978274
length of string ≈ 421 units(nearest whole number)

Answer:
2x⁶ + 16x⁵ + 30x⁴
Step-by-step explanation:
area of rectangle with height 2x⁴ and width x²+8x+15
area = height x width
2x⁴( x²+8x+15)
2x⁴( x²) +2x⁴(8x)+ 2x⁴(15)
2x⁴⁺² + 16x⁴⁺¹ + 30x⁴
2x⁶ + 16x⁵ + 30x⁴

7) The senior classes at High School A and High School B planned separate trips to
Yellowstone National Park. The senior class at High School A rented and filled 2 vans
and 7 buses with 407 students. High School B rented and filled 1 van and 7 buses with
389 students. Every van had the same number of students in it as did the buses. How
many students can a van carry? How many students can a bus carry?
Answer:
Number of students in each van = 18
Number of students in each bus = 53
Step-by-step explanation:
Given: The senior class at High School A rented and filled 2 vans and 7 buses with 407 students.
High School B rented and filled 1 van and 7 buses with 389 students.
Also, every van and the van had the same number of students in it.
Solution:
Let x denotes number of students in each van and y denotes number of students in each bus.
According to the given information,
[tex]2x+7y=407\,\,\,(i)\\x+7y=389\,\,\, (ii)[/tex]
From (ii), put [tex]x=389-7y[/tex] in (i)
[tex]2(389-7y)+7y=407[/tex]
[tex]778-14y+7y=407\\778-407=7y\\7y=371\\y=\frac{371}{7}=53[/tex]
Put [tex]y=53[/tex] in [tex]x=389-7y[/tex]
[tex]x=389-7(53)\\=389-371\\=18[/tex]
Number of students in each van = 18
Number of students in each bus = 53

the quotient of a number and 3 is 8
Answer:
The number is 24
Step-by-step explanation:
The quotient is the answer of a division problem. If a number is divided by 3 and the answer is 8, then the number would be 24. You could set it up into an equation.
x/3=8
then you multiply both sides by 3 and you will get
x=24
The quotient is indeed the number generated by dividing one integer by the other. Whenever a fraction is simplified, the division is the whole amount that results.
The quotient is the solution to a division issue. Whenever a number is divided by three and the answer is eight, the amount is twenty-four.Calculation of the equation:
[tex]\to \bold{\frac{x}{3}=8}\\\\\to \bold{x=8\times 3} \\\\\to \bold{x=24}[/tex]
Therefore, the final answer is "24".

Find the 96th term of the arithmetic sequence
-3, -14, -25, ...
Answer:
-1059
Step-by-step explanation:
Katelyn, this is super easy to understand.
Anyways, to find the 96th term of the sequence, first subtract -14 and -3. You may be thinking it is -17, but it is not. -17 is only if you are subtracting -14 and 3.
(-14) - (-3) = -14 + 3 = -11.
That means the difference between each number is -11.
Now all you have to do is take the -11 and multiply it by 96, which is -1056. Then, add the -1056 to -3, which is -1059. That should be your answer.
Your school may have taught you a different way, but this is my way.

Find the length of the segment indicated. Round your answer to the nearest tenth if necessary.
Answer:
Length of x ⇒ ( About ) 11.5; Option C
Step-by-step explanation:
~ Let us plan this question step-by-step. We know that the line segment with length 13.1 is a radii to the circle, as well as a hypotenuse to a right triangle. Respectively the hypotenuse of another triangle is a hypotenuse as well. By radii ≅, these two part of these two triangles are ≅ ~
1. If these two parts are ≅, the triangle with leg x has a hypotenuse of 13.1 as well ( through ≅ ). This would mean that Pythagorean theorem is applicable for this triangle, as to solve for line segment x.
2. By Pythagorean Theorem ⇒
6.2^2 + x^2 = 13.1^2,
38.44 + x^2 = 171.61,
x^2 = 133.17
Length of x ⇒ ( About ) 11.5

The equation y minus 3 = negative 2 (x + 5) is written in point-slope form. What is the y-intercept of the line?
–13
–7
2
8
Answer:
(B)
Step-by-step explanation:
We have the equation:
[tex]y-3=-2(x+5)[/tex]
Convert into Slope Intercept Form:
[tex]y-3=-2(x+5)[/tex]
[tex]-2*x=-2x\\-2*5 = -10[/tex]
[tex]y-3=-2x-10[/tex]
[tex]y-3+3=-2x-10+3\\\boxed {y=-2x-7}[/tex]
Slope-intercept form is [tex]y=mx+b[/tex].
Since '-7' is in the 'b spot', the y-intercept of the line would be -7, or option B.
Option B should be the correct answer.
Answer:
y intercept is -7
Step-by-step explanation:
y - 3 = -2 (x+5)
This is point slope form
We want to get this to slope intercept form
y=mx+b where m is the slope and b is the y intercept
Distribute
y-3 = -2x-10
Add 3 to each side
y-3+3 = -2x-10+3
y = -2x-7
The slope is -2 and the y intercept is -7

Step-by-step explanation:
Each brick is 13 inches long,5 inches wide,and 4 inches tall.of they used 11,700in3 of concrete how many Bricks did they make.
Answer:
45 bricks
Step-by-step explanation:
- With the knowledge of the 11,700 in^3 being used. We would need to have the measurements of the brick in that form as well. So in order to find the volume, we must multiply all sides. (13*5*4) = 260 in^3
- Now we have both numbers, we can just divide 11,700 by 260. This will give us 45. Meaning that 45 bricks are made.
