Answer:

15.9

Step-by-step explanation:

Draw CE and CF

Note ∠ECD = ∠CFD and ∠D = ∠D

so ΔCED ~ ΔFCD

then ED : CD = CD : PD

CD² = ED x PD = 12 x (9 + 12) = 252

CD = 15.9

Explanation:

Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.

the optimal way is to do it with Cramer's rule.

First, find the determinant and then find the determinant x, y, v, u.

Afterward, simply divide the determinant of variables by the usual determinant.

eg. [tex]\frac{Dx_{} }{D}[/tex] and etc.

I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.

Answer:

Step-by-step explanation:

a) 76.2 dm = 76.2 * 100 = 7620 mm

b) 2.1 km  = 2.1 *100000 = 210000

c) 0.123 Kg = 0.123 * 1000 = 123 g

d) 2.278*10¹¹ km = 2.278*10¹¹ * 10⁵ = 2.278* 10¹¹⁺⁶ = 2.278*10¹⁷ cm

e) 500 nm = 5*10⁻¹⁰ km

f) 35 mm = 35÷ 1000 = 0.035 m

g) 450 cm = 450 *10 = 4500 mm

h) 250 km = 250 * 100000 = 25000000 cm

i) 1500 micro gram = 0.0015 g

Answer:

[tex]225m^{2}[/tex]

Step-by-step explanation:

A square has 4 sides that are equal. 60 ÷ 4 = 15

15m per side

Area of square = b x h

Area of this square field = 15 x 15 = 225m^2

Step-by-step explanation:

when the exponent is an even number, the value is -1 and real.

when the exponent is uneven (odd), then the result is i and therefore imaginary.

i¹⁴ real

i⁴³ imaginary

i⁷ imaginary

i¹⁰ real

(4 - 5i)² = 4² - 40i + 25i² = 16 - 40i - 25 = -9 -40i imaginary

(7 + 2i)(7 - 2i) = 49 - 4i² = 49 + 4 = 53 real

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary

The description of the angles in the quadrilaterals are:

The quadrilateral is given as: JKLM

The opposite angles are:

The opposite angles are supplementary

So, we have:

[tex]J + L = 180[/tex]

[tex]K + M = 180[/tex]

Next, we test the options

Option (a)

[tex]J + L = 180[/tex]

[tex]125 + 35 = 160[/tex]

This is not true

Option (b)

[tex]J + L = 180[/tex]

[tex]48 + 132 =180[/tex]

This is true

Option (c)

[tex]K + M = 180[/tex]

[tex]12 + 78 = 180[/tex]

This is not true

Option (d)

[tex]K + M = 180[/tex]

[tex]120 + 60 = 180[/tex]

This is true

Option (e)

[tex]K + M = 180[/tex]

[tex]72 + 108= 180[/tex]

This is true

Option (f)

[tex]J + L = 180[/tex]

[tex]105 + 75 = 180[/tex]

This true

Hence, the description of the angles in the quadrilaterals are (b), (d), (e) and (f)

Answer:

The value of f(-1) in the given equation is -10.

Step-by-step explanation:

When we see f(-1), it means that -1 is represented as our value of x. So, knowing this information, we can plug this into our given equation.

f(-1) = -3(-1)² + 2(-1) - 5

Simplify the exponent on -1.

f(-1) = -3(1) + 2(-1) - 5

Multiply -3 by 1.

f(-1) = -3 + 2(-1) - 5

Multiply 2 by -1.

f(-1) = -3 - 2 - 5

Subtract 2 from -3.

f(-1) = -5 - 5

Subtract 5 from -5.

f(-1) = -10

Answer:

2a + b

Step-by-step explanation:

volume = 8a³ + b³ + 12a²b + 6ab² = (2a + b)³

volume = ( Side of the cube )³

( Side of the cube )³ = (2a + b)³

Answer:

exactly 135 grandparents

Step-by-step explanation:

Here, it asks us for how many grandparents spend less than two hours online, which is 54% as that is what the sample result says. Now, you must what 54% of 250 is to find the number of grandparents who spend less than 2 hours. To do this, you make 54% a decimal and multiply it with 250. You do 0.54 x 250, which gives you exactly 135 grandparents who spend less than two hours online.
