Answer:
6
Step-by-step explanation:
a=bh/2
12=4b/2, simplify = 12=2b/1
divide 2 to both sides
12=2b
6=b
Answer:
6 is the base
Step-by-step explanation:
to find the base, you do
b = 2 × A/h
b = 2 × 12/4 = 6
A = Area = 12
h = height = 4
b = base = 6

pls help
1/6
1/12
1/24
1/36
Answer:
1/36
Step-by-step explanation:
The dice color doesn't matter. All that matters is the number of times 6 is likely to come up. For every 6 sides of a dice, there is 1 side with "6" on it. This makes your probability of rolling a 6, 1:6 or 1/6. Since we are trying to find out how likely it is for you to roll 2 sixes in a row, multiply both of the probabilities. Since you are likely to roll one 6 every six rolls, multiply
1/6 x 1/6 to get 1/36:
[tex]\frac{1}{6} *\frac{1}{6} = \frac{1}{36}[/tex].
So for every 36 times you roll the dice, you can expect to roll 2 sixes.

The half-life of plutonium-244 is 80,000,000 years. Express the amount of plutonium-244 remaining as a function of time, measured in years with starting quantity A0.
The exponential function for the amount of plutonium-244 remaining as a function of time is given by:
[tex]A(t) = A(0)e^{-0.00000000866t}[/tex]
What is an exponential function?A decaying exponential function for the amount of a substance is modeled by:
[tex]A(t) = A(0)e^{-kt}[/tex]
In which:
A(0) is the initial value.k is the decay rate, as a decimal.The half-life of plutonium-244 is 80,000,000 years, hence [tex]A(80000000) = 0.5A(0)[/tex], which is used to find k.
[tex]A(t) = A(0)e^{-kt}[/tex]
[tex]0.5A(0) = A(0)e^{-80000000k}[/tex]
[tex]e^{-80000000k} = 0.5[/tex]
[tex]\ln{e^{-80000000k}} = \ln{0.5}[/tex]
[tex]-80000000k = \ln{0.5}[/tex]
[tex]k = -\frac{\ln{0.5}}{80000000}[/tex]
[tex]k = 0.00000000866[/tex]
Hence, the function is:
[tex]A(t) = A(0)e^{-0.00000000866t}[/tex]

Cal and Aaron are both re-doing their
landscaping and getting plants from the
same nursery. Cal bought I rose bush and 12
shrubs for $147, while Aaron bought 5 rose
bushes and 6 shrubs for $87. Find the cost of
one rose bush and one shrub.
Answer:
Rose bush - $3 and shrub - $12Step-by-step explanation:
Let rose bush = x, shrub = y
Equations:
x + 12y = 1475x + 6y = 87Solve the system by elimination, multiply the second equation by 2 and subtract the first equation:
5x*2 +6y*2 - x - 12y = 87*2 - 14710x - x = 174 - 1479x = 27x = 3Find the value of y:

Your classmate is standing on the right side of a monument. She has a piece of rope staked at the base of the monument. She extends the rope to the cardboard square she is holding lined up to the top and bottom of the monument. Use the information in the diagram above to approximate the height of the monument to the nearest tenth.
The height is the hypotenuse side of the right triangle formed by the
cardboard and the ropes to the top and bottom of the monument.
Correct response:
The height of the monument is approximately 14.63 feet.Calculation methods usedThe possible diagram in the question as obtained from a similar question posted online is attached.
From the diagram, we have;
The angle, θ₁ formed by the rope and the 7.2 ft. segment is given as follows;
Therefore;
The angle formed by the segment from the cardboard square to the top of the monument, θ₂, is given as follows;
90° = θ₁ + θ₂Which gives;
θ₂ ≈ 90° - 37.376° = 52.624°
Therefore;
[tex]tan(\theta_2) = \mathbf{\dfrac{d}{7.2} }[/tex]
Which gives;
d = 7.2 × tan(θ₂)
Therefore;
d = 7.2 × tan(52.624°)
Using trigonometric ratios of tangents of angles that sum up to 90°, we have;
[tex]tan(52.624^{\circ}}) = \mathbf{ \dfrac{72}{55} }[/tex]
Which gives;
[tex]d = 7.2 \times \dfrac{72}{55} \approx \mathbf{9.43}[/tex]Height of the monument, h = d + 5.2
Therefore;
h ≈ 9.43 + 5.2 = 14.63

Step-by-step explanation:
if a, b, c, d are four consecutive whole numbers and a + b + c +d =78. find the value of c.
==========================================================
Explanation:
a,b,c,d are consecutive whole numbers. This means one follows right after the other. Example: 5,6,7,8 or 50,51,52,53
In general we have:
a = some whole numberb = a+1c = b+1 = (a+1)+1 = a+2d = c+1 = (a+2)+1 = a+3The sequence a,b,c,d is the same as a,a+1,a+2,a+3
Add those expressions together and set the sum equal to 78. Then solve for 'a'.
a+b+c+d = 78
a+(a+1)+(a+2)+(a+3) = 78
4a+6 = 78
4a = 78-6
4a = 72
a = 72/4
a = 18
This leads to
b = a+1 = 18+1 = 19c = a+2 = 18+2 = 20 which is the answerd = a+3 = 18+3 = 21The four consecutive whole numbers for a,b,c,d are 18,19,20,21 in that order.
As a check,
a+b+c+d = 18+19+20+21 = 78
which confirms our answer.
