Answer:
1540 square in-17.4π in
Step-by-step explanation:
The box's area is 1540 square inches, and the volume of a sphere is 4πr. So we do 4*π*r, which is 4π*4.35, and simplify it to 17.4π. Then we subtract that from the 1540 square in to get the final answer of 1540-17.4π
Reference: π is approximately 3.1415926
is it 290 or 70 is conjugate angle

There is a direct proportionality between volume and temperature (in Kelvin) of a gas. The volume of a sample of a gas at 277 Kelvin is 2.1883 L.
Which of the following shows a direct variation equation relating the volume V and the temperature T?
Options:
1. V= 0.0079T
2. V= 126.6T
3. T=606.2V
4. T= 0.0079V
Answer:
2. V= 126.6T4. T= 0.0079VExplanation:
V = kT
[ where k is constant ]
277 = k(2.1883)
k = [tex]\frac{277}{2.1883}[/tex]
k = 126.6
Therefore: V = 126.6TVk = T
277k = 2.1883
k = 2.1883/277
k = [tex]7.9 * 10^{-3}[/tex]
V * [tex]7.9 * 10^{-3}[/tex] = T
T = 0.0079V
Therefore T = 0.0079V

Answer:
a/
36s ~ 360º
1s ~ ?
so 1 * 360 / 36 = 10º
b/
36*3/4=27s (closest)
36*1/4=9s (farthest)
c/
20ft
Answer:
a) 10°
b) closest: 27 seconds
farthest: 9 seconds
c) 20 ft
Step-by-step explanation:
a) Angles around a point add up to 360°, therefore 1 rotation = 360°
If it makes one rotation in 36 seconds, then there are 10° per second as 360/36 = 10
b) closest to wall: this will be a 3/4 rotation:
3/4 of 36 seconds = 0.75 x 36 = 27 seconds
farthest from wall: 1/4 rotation:
1/4 of 36 = 0.25 x 36 = 9 seconds
c) 18 seconds is half of 36 seconds. Therefore, you will have made a 1/2 rotation. So you will be on the same horizontal plane as the start position, but on the opposite side of the circle (see attached diagram).
Therefore, you will be 20ft away from the wall (shown in blue).

Step-by-step explanation:
A recursive formula lets us calculate a term in the sequence by multiplying the previous term by the common ratio r
for the sequence
- 3, 9 , - 27 , 81....
the common ratio r is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3
Then the recursive formula is
f(n) = - 3 f(n - 1) if n > 1
f(1) = - 3
option D
Answer:
D)
Step-by-step explanation:
A recursive formula always has two parts: the value of an initial term (or terms), and an equation defining [tex]a_n[/tex] in terms of preceding terms.
From inspection, the initial term is -3
[tex]\implies a_1=-3[/tex]
[tex]\implies f(1)=-3[/tex]
From inspection, we can see that each term is the preceding term multiplied by -3. Therefore, the sequence can be defined as:
[tex]a_n=-3(n-1)[/tex]
[tex]\implies f(n)=-3f(n-1)[/tex]
So the recursive formula for the sequence is D)
[tex]f(n)=\left \{ {{f(1)=-3} \atop {f(n)=-3f(n-1)}} \right.[/tex]

Vertical angles are opposite angles made by intersecting lines.
Any of these would apply: 1,6 or 2,5 or 3,8 or 4,7
Supplementary angles are two angles that add up to 180. Any two angles that are side by side are 180. For example 1,2 or 4,8 etc..
Answer:
supplementary = <5 and <1
vertical = <5 and <2
Euclid Street is parallel to Lambert Street. City Hall is
located between the streets. From City Hall, a straight
road leads to Euclid Street, intersecting it at a 51°
angle. Another straight road leads to Lambert Street,
intersecting it at a 37° angle. Find X. EXPLAIN and
show your method.
Answer:
88
Step-by-step explanation:
Imagine a line through City Hall parallel to the given streets. The angle between that and the path to Euclid Street is 51°, congruent with the alternate interior angle marked 51°.
The angle between our imaginary line and the path to Lambert Street is 37°, congruent with the alternate interior angle marked 37°.
The value of x° is the sum of those two angles:
x° = 51° +37°
x = 88
__
Alternate solution
If you extend the path to Euclid Street until it intersects Lambert Street, the alternate interior angle theorem tells you the angle it makes with Lambert Street is 51°. The angle x° is an external angle to the triangle that now has 51° and 37° as remote interior angles. As such, x is the sum of 51 and 37:
x = 51 +37 = 88

A line passes through the point (2,7) and has a slope of 9. Write an equation in slope-intercept form for this line.
Hi there!
We are given a point that the line passes through and the slope of the line, so we can use Point-Slope Form:

Answer: 1 is correct
2 is correct
3 is correct
4 is correct
5 is correct

7 is correct
8 is wrong it should be because you wouldn't add you would subtract it and the other number is negative so it would be x=-26
9 is correct
10 is correct
13 is correct
14 I think is correct
I think 15 is incorrect because if he says one less than twice the number of last year then I think you first should subtract 1 from 25 and then divide by 2 this would give you 17 packages
and I think 16 is correct too.

A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path. A circle has a radius of 28 feet. A larger circle goes around the smaller circle that is 4 feet wide. About how many feet of fencing are needed to go around the pool path? Use 3. 14 for Pi. 88 ft 100 ft 176 ft 201 ft.
There is 201 feet of fencing are needed to go around the pool path.
Given
A circular swimming pool has a radius of 28 ft.
There is a path all the way around the pool that is 4 ft wide.
A fence is going to be built around the outside edge of the pool path.
A circle has a radius of 28 feet.
A larger circle goes around the smaller circle that is 4 feet wide.
Circumference;For the length of the fence, we need to find the circumference of the outside of the pool path.
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= 28 + 4 = 32 feet
The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter;
[tex]\rm Perimeter = 2\pi r[/tex]
Where r is the radius.
Substitute all the values in the formula;
[tex]\rm Perimeter = 2\pi r\\\\\rm Perimeter = 2\times 3.14 \times 32\\\\Perimeter = 201[/tex]
Hence, there is 201 feet of fencing are needed to go around the pool path.

A teacher wants to find the average (mean) grade on a math test. The gradebook program can provide data about the class as a stem-and-leaf plot or as a box-and-whisker plot. Which plot should she use? Why?
Answer:
Box-and-whisker plot
Step-by-step explanation:
Box-and-whisker plot is a graph commonly used to not only find the mean but find the minimum, maximum, third and first quartile. In order to calculate the mean of a set of data, you have to rearrange the data and the middle number separating one half of the set, from the other half of the set is the mean. Box-and-whisker plot can accurately show the average grade on this math test.

The junior class sold boxes of pecans at $6 each and boxes of peanuts at $5 each. They sold a total of 82 boxes for $440. How many boxes of pecans and peanuts did they sell?
I NEED THE EQUATIONS...I can get the number of pecans and peanuts..I just need the equation to find them..please help me
This is Algebra
Answer:
Following are the required equations
[tex]x +y=84[/tex]
[tex]6x +5y=440[/tex]
Step-by-step explanation:
Let x boxes of pecans and y boxes of peanuts sold.
Total no of boxes sold = 84
[tex]\implies x +y=84[/tex]
Cost of one box of pecan =$6
So, cost of x boxes of pecans =$6x
Cost of one box of peanuts = $5
So, cost of y boxes of peanuts =$5y
Total sales = $440
[tex]\implies 6x +5y=440[/tex]

X^2+y^2=128
Find the intersection of the line and the circle
Answer:
(-8, 8)
Step-by-step explanation:
Plug in the y from the top equation into the y of the bottom equation
x² + (x + 16)² = 128
x² + x² + 32x + 256 = 128
Subtract 128 from both sides to make it equal to zero
2x² + 32x + 256 = 128
- 128 - 128
2x² + 32x + 128 = 0
Divide both sides by 2
(2x² + 32x + 128)2 = 0/2
x² + 16x + 64 = 0
Factor the equation
(x + 8)(x + 8) = 0
We see that x will have to be -8 for it to equal zero
so x = -8
Plug the new x into one of the original equations; let's use the top one
y = -8 + 16
y = 8
