help me A box of cereal weighs 600 grams. How much is this weight in pounds? Explain or show your reasoning. (Note: 1 kilogram = 2.2 pounds)
The box of cereal weighs
Question Blank
type your answer...
pounds.
Answer:
1.32lb
Step-by-step explanation:
We will first have to calculate the grams to kilogram,
600g = 0.6kg
Since 1 kilogram represents 2.2 pound we will multiply 0.6 by 2.2 to get the pounds
0.6 * 2.2
= 1.32lb

Answer:
79°
( vertically opposite angles are equal. So, <AOB = < A'OB' )
Answer:
∠ A'OB' = 79°
Step-by-step explanation:
∠ AOC = ∠ C'OA' = 35° ( vertical angles )
BOB' is a straight angle , thus
∠ COB' = 180° - (79 + 35)° = 180° - 114° = 66°
C'OC is a straight angle, thus
∠ A'OB' = 180° - (66 + 35)° = 180° - 101° = 79°
q/2 - p/3 = 1/6

X=59÷3 and y=29
Step-by-step explanation:
Days the answer
Answer:
p = 13, q = 9
Step-by-step explanation:
Given the 2 equations
[tex]\frac{q}{2}[/tex] - [tex]\frac{p}{3}[/tex] = [tex]\frac{1}{6}[/tex] ( multiply through by 6 to clear the fractions )
3q - 2p = 1 → (1)
[tex]\frac{p}{2}[/tex] - [tex]\frac{q}{6}[/tex] = 5 ( multiply through by 6 to clear the fractions )
3p - q = 30 , that is
- q + 3p = 30 → (2)
Multiplying (2) by 3 and adding to (1) eliminates the term in q
- 3q + 9p = 90 → (3)
Add (1) and (3) term by term to eliminate q
7p = 91 ( divide both sides by 7 )
p = 13
Substitute p = 13 into (2) for corresponding value of q
- q + 3(13) = 30
- q + 39 = 30 ( subtract 39 from both sides )
- q = - 9 ( multiply both sides by - 1 )
q = 9
Thus p = 13 and q = 9

Answer:
the number of grain of salt in the packet
5,401.23
Step-by-step explanation:
1 grain .................... 6.48x10^-5 kg salt
x grain.................... 0.35 kg salt
x= 5,401.23
a) The number of grains of salt in the packet are 5.4 x [tex]10^6[/tex] grains. b) The answer in part (a) is unlikely to be the actual number of grains of salt in the packet because the weight of a grain of salt can vary.
a) The number of grains of salt in the packet can be calculated as follows:
number of grains = total weight of salt / weight of one grain
= 0.35 kg / 6.48 x [tex]10^{-5[/tex] kg/grain
= 5.4 x [tex]10^6[/tex] grains
b) The answer in part (a) is unlikely to be the actual number of grains of salt in the packet because the weight of a grain of salt can vary. The average weight of a grain of salt is 6.48 x [tex]10^{-5[/tex] kg, but the actual weight can be anywhere from 6.2 x [tex]10^{-5[/tex] kg to 6.7 x [tex]10^{-5[/tex] kg. This means that the actual number of grains of salt in the packet could be anywhere from 5.2 x [tex]10^6[/tex] grains to 5.6 x [tex]10^6[/tex] grains.
In addition, the density of salt can also vary slightly, which would also affect the number of grains of salt in the packet.
Therefore, the answer in part (a) is only an estimate of the actual number of grains of salt in the packet.

Step 1: Define equation
[tex]\frac{3.6}{0.2(6y + 1)} =\frac{9}{0.5y}[/tex]
Step 2: Solve for y
Distribute 0.2: [tex]\frac{3.6}{1.2y + 0.2} =\frac{9}{0.5y}[/tex]Cross-multiply: [tex]9(1.2y + 0.2) =3.6(0.5y)}[/tex]Distribute: [tex]10.8y + 1.8 =1.8y[/tex]Subtract 1.8y on both sides: [tex]9y + 1.8 =0[/tex]Subtract 1.8 on both sides: [tex]9y = -1.8[/tex]Divide both sides by 9: [tex]y = -0.2[/tex]Step 3: Check
Plug in y to verify it's a solution.
Substitute: [tex]\frac{3.6}{0.2(6(-0.2) + 1)} =\frac{9}{0.5(-0.2)}[/tex]Multiply: [tex]\frac{3.6}{0.2(-1.2 + 1)} =\frac{9}{-0.1}[/tex]Add: [tex]\frac{3.6}{0.2(-0.2)} =\frac{9}{-0.1}[/tex]Multiply: [tex]\frac{3.6}{-0.04} =\frac{9}{-0.1}[/tex]Divide: [tex]-90=-90[/tex]Here we see that -90 does indeed equal -90. ∴ y = -0.2 is indeed a solution of the equation.

A train leaves the station at time t0. Traveling at a constant speed, the train travels 360 kilometers in 3 hours. Write a function that relates the distance traveled d to the time t
Answer:
d=120t
Step-by-step explanation:
i dont have an explanation for this i just got it wrong and im giving you the answer hope this helps also you have to put it in exactly like this
d = 120t
^^^^^^^^
The function that relates the distance traveled d to the time t is (d = 120t) and this can be determined by using the formula of speed.
Given :
A train leaves the station at time t0. Traveling at a constant speed, the train travels 360 kilometers in 3 hours.The following steps can be used in order to determine the function that relates the distance traveled d to the time t:
Step 1 - The formula of speed can be used in order to determine the function that relates the distance traveled d to the time t.
Step 2 - The speed formula is given below:
[tex]\rm s = \dfrac{d}{t}[/tex]
where distance is 'd' and time is 't'.
Step 3 - Now, substitute the values of d = 360 and t = 3 in the above formula.
[tex]\rm s = \dfrac{360}{3}[/tex]
s = 120 km/hr
Step 4 - Now, at time 't' the distance is given by:
[tex]120=\dfrac{d}{t}[/tex]
d = 120t

Step-by-step explanation:
5/2=15/6=20/8=2.5
From the given equation, list the values of A, B, and C when put into
standard form. 6y - 2x = 5
A = -2, B = 6, C =5
A = 2, B = 6, C = 5
A = 2, B = -6, C = -5
Rewriting in standard form puts the x variable before the y variable:
-2x + 6y = 5
A is the value with x, B is the value with y and c is after the equal sign.
A = -2, B =6, C= 5

110 meters of fencing are used to fence a rectangular pasture of 750 square meters of farmland. If the length of the pasture is longer than the width, what is the width of the pasture in meters?
Answer:
25mStep-by-step explanation:
Perimeter of the rectangular pasture P = 2(L+W)
Area A = LW
L is the length
W is the width
Given
Perimeter = 110m
Area = 750m
If the length of the pasture is 40m longer than the width, then L = W+40
110 = 2L+2w
55 = L+W .....1
750 = LW.....2
Solving simultaneously
from 1; L = 55-W
substitute into 2;
750 = (55-W)W
750 = 55W-W²
-W²+55W -750 = 0
W²-55W+750 = 0
(W²-25W)-(30W+750) = 0
W(W-25)-30(W-25) = 0
(W-25)(W-30) = 0
W-25 = 0 and W-30 = 0
w = 25m and 30m
Since L = 55-W
L = 55-25 = 30m and;
L = 55-30 = 25m
Since we are told that length id longer than the width then, the width we are going to use is 25m
