Answer:

j=7

Step-by-step explanation:

10=2j-4                          add 4 on both sides

10+4=2j                        

14=2j                                divide by 2 on both sides

Answer:

K = 40 degrees

I = 50 degrees

Step-by-step explanation:

Recall that the addition of all three internal angles of a triangle must give 180 degrees

Then 90 + (5 x - 5) + (4 x + 14) = 180

90 + 5 x + 4 x - 5 + 14 = 180

99 + 9 x = 180

9 x = 180 - 99

9 x = 81

x = 81 / 9

x = 9

Then we can find the measures of angles K and I as:

K = 5 x - 5 = 5 (9) - 5 = 40 degrees

I = 4 x + 14 = 4 (9) + 14 = 36 + 14 = 50 degrees

A triangular prism is a three-dimensional geometric shape that consists of two triangular bases and three rectangular faces connecting them. It is a polyhedron with six faces, nine edges, and six vertices.

The two triangular bases of a triangular prism are congruent and parallel to each other. The rectangular faces are perpendicular to the triangular bases, and their lateral edges connect the corresponding vertices of the triangular bases.

The triangular bases are identical and parallel to each other. Each base has three vertices, three edges, and one face.There are three rectangular lateral faces connecting the corresponding vertices of the triangular bases. Each lateral face has two edges and one face.

Measure the shape yourself and follow the explanation.

Step-by-step explanation:

Measure each side of the Triangles with your ruler. Record it.

For example,

I measured and got 3cm, 3.5cm, 3.5cm.

Multiply by scale factor r 2.

for example, 3cm × 2 = 6cm

3.5cm × 2 = 7.0cm

3.5cm × 2 = 7.0cm

Use your pencil to draw your new numbers to form the new Triangle.

As for the second shape, measure each four sides using ruler

for example, I measured and had 4cm, 6cm, 4cm, 6m.

Multiply by scale factor r 2.

for example, 4cm × 1/4 = 1 cm

6cm × 1/4 = 1.5cm

4cm × 1/4 = 1 cm

6cm × 1/4 = 1.5cm

Use your ruler to measure 1cm, 1.5cm, 1cm and 1.5cm, then to draw your new shape

Bob had 50 pencils in the beginning.

A fractional number is expressed in the form -

x/y    {where y ≠ 0)

Given is that Bob gave four - fifths of his pencils to Barbara, then he gave two - thirds of the remaining pencils to bonnie.

Assume that he had {x} pencils in the beginning. We can write -

4x/5 + 2/3(x - 4x/5) = 10

4x/5 + 2x/3 - 8x/15 = 10

x(4/5 + 2/3 - 8/15) = 10

x = 10/0.93

x = 50

Therefore, Bob had 50 pencils in the beginning.

After applying the distributive property, Ezra's expression was 8y + 16. After he used the commutative property, his expression was 16 + 86

An equation is an expression showing the relationship between two or more numbers and variables.

The distributive property is one of the basic math principles. It states that for an expression in the form:

a(b + c) = ab + ac

Commutative property is given by:

a + b = b + a

Given the expression:

8(y + 2)

Applying the distributive property:

= 8y + 16

Applying the commutative property:

= 16 + 8y

The expression 8(y + 2) is equivalent to 16 + 8y

Applying the logarithmic function, it is found that:

The age of a fossil with a proportion c of carbon 14 remaining is given by:

\(t(c) = -3970\ln{c}\)

If the fossil has 47% of carbon-14 remaining, we have that \(c = 0.47\), and thus:

\(t(0.47) = -3970\ln{0.47} = 2997\)

For a fossil that is 7000 years old, we have that \(t(c) = 7000\), and hence:

\(t(c) = -3970\ln{c}\)

\(\ln{c} = -\frac{3970}{7000}\)

\(e^{\ln{c}} = e^{-\frac{3970}{7000}}\)

\(c = 0.5671\)

The amount of the investment after 8 years will be, $4,357.64

Given, $500 is invested in an account earning 7% interest compounded quarterly.

We have to find the value of the invested amount after 8 years,

as, Amount = P(1 + r/100)^t

where, P is the amount of money invested, r is the rate of interest and t is the amount of time

Amount = 500(1 + 7/100)^(8×4)

Amount = 500(1.07)^32

Amount = 500×8.715

Amount = 4,357.635

So, the amount of the investment after 8 years will be, $4,357.64

Additional comment

Some calculators compute roots using logarithms. Since the logs of negative number are not real, they will give you an error if you try to do this directly. You have to know that the odd index root of a negative number is the opposite of the same root of its absolute value.

The prime factoring of 108 is 2²·3³. Factoring out the perfect cube gives the simplified form ...

The entrepreneur's revenue is  $2325x, entrepreneur's cost is $33,750 + $1700x and entrepreneur's profit from x sold-out performances is  $625x - $33,750

The entrepreneur's revenue from x sold-out performances is given by the formula:

Revenue = (Price per Performance) x (Number of Performances)

Revenue = $2325 x x

Revenue = $2325x

The entrepreneur's cost from x sold-out performances is given by the formula:

Cost = Overhead + (Production Cost per Performance) x (Number of Performances)

Cost = $33,750 + $1700x

The entrepreneur's profit from x sold-out performances is the revenue minus the cost:

Profit = Revenue - Cost

a= 28

b= 17

c = 15

C = arcCos [ (a^2 + b^2 - c^2)  /  (2 * a * b) ]

C = arcCos[ 28^2 + 17^2 - 15^2  / 2*28 *17 ]

C = arcCos[ 784 + 289 -225 / 952 ]

C = arcCos [ 848 / 952 ]

C = arcCos [0.8907563]

C = 27.03 °

To find the number of bacteria present after 12 hours, we simply need to substitute t=12 in the given equation:

\(n(12) = 500e^{1.8}\)

n(12) ≈ 3024.82

The value of E(x) is 0.8695 and Var(x) is 0.5877

From the question, we have the following parameters that can be used in our computation:

n = 23

x = 4

k = 5

The value of E(x) is calculated as

E(x) = xk/N

Substitute the known values in the above equation, so, we have the following representation

E(x) = 4 * 5/23

E(x) = 0.8695

This is calculated as

Var(x) = E(x) * (1 - k/n) * ([n - x]/[n - 1])

Substitute the known values in the above equation, so, we have the following representation

Var(x) = (4 * 5/23) * (1 - 5/23) * ([23 - 4]/[23 - 1])
