Answer:
Using the Charles law equation
V1/T1=V2/T2
V1=25L
V2=?
T1=110°C
T1=110+273
T1=383K
T2=266°C
T2=266+273
T2=539K
25L/283K=T2/539K
T2=(25L×539K)/283K
T2=47.6L
Therefore at the temperature of 266°C, it will occupy 47.6L of volume.

Find the equation of the line that has a slope of 1 and passes through the point (-3,7) write the equation in point-slope form
Answer:
y - 7 = 1(x + 3)
Step-by-step explanation:
Point-Slope Form: [tex]y-y_1=m(x-x_1)[/tex]
[tex]{\large \textsf{where}\ m\ \textsf{is the slope}}\ \textsf{and}\ {\large{(x_1,y_1)\ \textsf{is the given coordinate.}}[/tex]
Given info:
A line with a slope of 1 and passes through the point (-3, 7).
m = 1x₁ = -3, y₁ =7Substitute the given values into the formula and simplify.
[tex]\implies y-7=1(x-(-3))[/tex]
[tex]\implies y-7=1(x+3)[/tex]
Travis spies an owl in a tall tree. He estimates the height of the tree to be 85 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Travis to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Travis step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Please help!!
Answer:
63.44 feet
Step-by-step explanation:
tan(68 degrees)= 85/y
y tan (68 degrees)=85
y=85/tan(68 degrees) ( cross multiply)
y = 34.34 feet
tan (41 degrees)=85/x+y
(x+y)tan(41 degrees)=85
x+y=85/tan 41 degrees
x=85/tan(41 degrees) - y
x= 85/tan (41 degrees)-(34.34) (cross multiply)
Therefore, Travis stepped back 63.44 feet to gain a better view!

Megan needs 4200 sheets of paper how many packs should she buy if each pack has 500 sheets
Answer:
she will need 8.4 so just get 9
If each box has 500 sheets, Megan should purchase 9 packs if she needs 4200 sheets of paper.
What are arithmetic operations?The area of arithmetic operations encompasses the study of numbers and their operations, which are essential to all other branches of mathematics. These systems use the four operations of addition, subtraction, multiplication, and division as their foundation.
It is given that, Megan purchases 4200 sheets of paper because each box has 500 sheets.
Suppose x be the number of packs,
Applying division to select how to share pack equitably among a group, divide the object into equal halves or groups.
The number of packs needed will be,
x=4200/500
x=8.4 ≈ 9
Thus, she should buy 9 packs if each pack has 500 sheets.

The measures of the exterior angles of an octagon are x°, 2x", 3x°, 4x °, 6x°, 7xº,
8xº, and 9x °. Find the measure of the largest exterior angle.
Answer:
216
Step-by-step explanation:
Total of octagon amount is 1080, so set it equal.
x + 2x + 3x + 4x + 6x + 7x + 8x + 9x = 1080
45x = 1080
/45 /45
x = 24
Then plug in for largest number.
9 (24) = 216

Last week Connor and his roommates ate 1 1/6 cartons of yogurt, and this week they ate 3 cartons. How much more yogurt did they eat this week compared to last week?
Step-by-step explanation:
last week they ate 1 1/6 = 6/6 + 1/7 = 7/6 cartons.
this week they ate 3 = 3×6/6 = 18/6 cartons.
so, how much more did they eat ?
it is not fully clear to me, if we need to find the absolute difference in cartons, or if we need the factor between both amounts (like "how many times did they eat more ?").
to be safe I give you both.
in absolute difference :
18/6 - 7/6 = 11/6 cartons = 1 5/6 cartons more.
as factor :
7/6 × x = 18/6
7x = 18
x = 18/7
they ate 18/7 = 2 4/7 times more

what is the correct equation
Answer: y = 0.4x
In fraction form, this is y = (2/5)x
================================================
Explanation:
For each row, divide the y over x values
Row One: y/x = 0.8/2 = 0.4Row Two: y/x = 4/10 = 0.4Row Three: y/x = 6/15 = 0.4Row Four: y/x = 10/25 = 0.4We end up with the same thing each time.
Since y/x = 0.4, this rearranges to y = 0.4x
Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4

A convention center is in the shape of a rectangular pyramid with a height of 221 m. Its base measures 522 m by 500 m. Find the volume of the convention center. If necessary, round your answer to the nearest tenth.
19,227,000 m3
9,613,500 m3
57,681,000 m3
1,243 m3
Answer:
[tex]19\ 227\ 000\ m^{3}[/tex]
Step-by-step explanation:
The equation for volume of a rectangular prism is
[tex]V = \frac{hB}{3}[/tex]
[tex]B = lw[/tex]
V is volume
B is base
so if the base measures 522 multipled by 500
multiply length and width B = 522 • 500 = 261000
height is 221
V = [tex]\frac{hB}{3}[/tex]
Fill in variables V = [tex]\frac{221(251000)}{3}[/tex]
Multiply V = [tex]\frac{57681000}{3}[/tex]
Divide V = [tex]19\ 227\ 000\ m^{3}[/tex]
8. The circle below is centered at the point (5,-2) and has a radius of length 4. Write the equation for the circle.
Answer:
(x - 5)² + (y + 2)² = 16
Step-by-step explanation:
Equation of a circle formula: (x - a)² + (y - b)² = r²
where (a, b) is the center of the circle and r is the radius
Given, center = (5, -2) and radius = 4
Substitute this information in the equation of a circle formula.
⇒ Equation of the circle: (x - 5)² + (y + 2)² = 16
