Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.
lowkey hope this helped you, good luck whatever you need it for Imaooo

Write the slope-intercept form of the equation of the line.
through: (4,1), perpendicular to y = -2x + 5
Answer:
y = -10x + 5 and y = 2/5x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
for your first problem, just plug in the m and b values to complete the equation.
1.) y = mx + b ⇒ y = -10x + 5
plug in -10 for x (slope) and 5 for b (y-intercept)
and for the second problem...
since you're given a value for slope as well as a coordinate pair, all you need to do is plug those values into the equation for their respective variables and then solve for b. (it doesn't matter what order you plug values in, but i'm going to fill them in in the order of the equation; y, m, and x)
1.) plug in -1 for y
y = mx + b ⇒ -1 = mx + b
2.) plug in 2/5 for m
-1 = mx + b ⇒ -1 = 2/5x + b
3.) plug in -5 for x
-1 = 2/5x + b ⇒ -1 = 2/5(-5) + b
now it's time to solve for b! start by multiplying 2/5 and -5.
-1 = 2/5(-5) + b ⇒ -1 = -2 + b
add 2 to both sides of the equation. on the right side, it cancels itself out. on the left side, adding 2 to -1 gives you 1.
and you're left with 1 = b! :)
therefore, y = 2/5x + 1
i hope this helps! have a great day <3

Answer:
A.)
Step-by-step explanation:
5.7^2+3.2^2=42.73
Sqrt of 42.73=6.5
Given :
Length of leg in a triangle = 3.2 cm
Length of leg of another triangle = 5.7 cm
We know that :
[tex]\color{hotpink}\tt {hypotenuse}^{2} \color{plum} = {base}^{2} + {height}^{2} [/tex]
Which means :
[tex] = \tt {3.2}^{2} + {5.7}^{2} = {h}^{2} [/tex]
[tex] =\tt 42.73 = {h}^{2} [/tex]
[tex] =\tt \sqrt{42.73} = h[/tex]
[tex]\hookrightarrow\color{plum} \tt6.5 \: cm= hypotenuse[/tex]
Thus, the hypotenuse of this triangle = 6.5 cm
Therefore, the correct option is (A) 6.5 cm

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for fencing. He knows that the area of
the yard is 51 square meters and that the width is 5.2 meters longer than the length. Which equation could be solved to determine the
dimensions of the backyard, where the length is / and the width is w?
0=w/2+5.2w -51
0=/2+5.2/-51
4w +10.451
4/+10.4 = 51
Answer:
0=w^2-5.2w-51
Step-by-step explanation:
51=width x length
length=width-5.2
substitute for length
51=width x (width-5.2)
51=w^2-5.2w
0=w^2-5.2w-51

what is the distance between coordinates (-6.25,5) and (-3.75,2)
Answer:
[tex]\sqrt{15.25}[/tex]
Step-by-step explanation:
To find the distance, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-6.25,5) and (-3.75,2)
[tex]d=\sqrt{(-6.25-x_1)^2+(5-y_1)^2}\\d=\sqrt{(-6.25-(-3.75))^2+(5-2)^2}\\d=\sqrt{(-6.25+3.75)^2+(5-2)^2}\\d=\sqrt{(-2.5)^2+(3)^2}\\d=\sqrt{6.25+9}\\d=\sqrt{15.25}[/tex]
Therefore, the distance between the two coordinates is [tex]\sqrt{15.25}[/tex], or approximately 3.91.
I hope this helps!

Answer:
10b - 60
Step-by-step explanation:
So the question is asking to use the Distributive Property with giving the equation 10(b - 6).
So the distributive property is just multiplying the number outside the parenthesis with the numbers inside the parenthesis, so lets implement that :
(10 * b - 6 * 10)
10b - 60
Answer:
The answer is 6
Step-by-step explanation:
10(b - 6) =
10 x b = 10b
10 x 6 = 60
10b = 60
10/10 10/60
= 6

Given the equation A=250(1.1)t, you can determine that the interest is compounded annually and the interest rate is 10%. Suppose the interest rate were to change to being compounded quarterly. Rewrite the equation to find the new interest rate that would keep A and P the same.
What is the approximate new interest rate?
Convert your answer to a percentage, round it to the nearest tenth, and enter it in the space provided, like this: 42.53%
Answer:
The new interest rate is about 0.1038.
As a percent, this is about 10.4%.
Step-by-step explanation:
We are given:
[tex]\displaystyle A=250(1.1)^t[/tex]
From this, we can determine that the interest rate is compounded annually at 10%.
We want a new equation that keeps A and P but the interest rate is compounded quarterly.
Compound interest is given by:
[tex]\displaystyle A=P(1+\frac{r}{n})^{nt}[/tex]
Since we are compounding quarterly, n = 4. Since the rate is 10%, r = 0.1. P stays at 250. Therefore:
[tex]\displaystyle A=250(1+\frac{0.1}{4})^{4t}[/tex]
Add:
[tex]\displaystyle A=250(1.025)^{4t}[/tex]
Rewrite:
[tex]A=250((1.025)^4)^t[/tex]
So:
[tex]A\approx 250(1.1038)^t[/tex]
Therefore, the approximate new interest rate is 1.1038 - 1 or about 0.1038.
As a percent, this will be 0.1038 or about 10.4%.

Answer:
Step-by-step explanation:
4). Surface area of front and back = 2(lengh × height)
= 2(7×3)
= 63 cm²
Surface area of top and bottom = 2(length × width)
= 2(8×7)
= 112 cm²
Surface area of left and right = 2(width × height)
= 2(8×3)
= 48 cm²
Total surface area = 63 + 112 + 48
= 223 cm²
5). Surface area of top and bottom = 2πr²
= 2π(4)²
= 32π
= 100.53 cm²
Surface area of middle = h(π × d)
= 4(π × 8)
= 32π
= 100.53 cm²
Total surface area = 32π + 32π
= 64π
= 201.06 cm²
6). Surface area of front and back = [tex]2[\frac{1}{2}(\text{Base})(\text{Height)}][/tex]
= Base × Height
= 6 × 8
= 48 cm²
Surface area of bottom = 6 × 11
= 66 cm²
Surface area of the left = 8 × 11
= 88 cm²
Surface area of right = 10 × 11
= 110 cm²
Total surface area = 48 + 66 + 88 + 110
= 312 cm²

In the figure below, UX and UV are tangent to the circle centered at 0. The segment XV passes through the center of the
circle. Given that UX= 15.7 and XV = 8.5, find XW.
Help
Answer:
2.5
Step-by-step explanation:
The computation of the XW is shown below
As triangle UVX is a right angle
So
VU^2 = XU^2 - VX^2
VU^2 = 15.7^2 - 8.5^2
VU^2 = 246.49 - 72.25
VU^2 = 174.24
VU = 13.2
As VU = WX because of same point tangent
NOw XW is
= UX - UW
= 15.7 - 13.2
= 2.5
