Answer:

[tex]k = \frac{3}{10} [/tex]

Step By Step Explanations:

1) Multiply both sides by 2k.

[tex]3 = 5 \times 2k[/tex]

2) Simplify 5 × 2k to 10k.

[tex]3 = 10k[/tex]

3) Divide both sides by 10.

[tex] \frac{3}{10} = k[/tex]

4) Switch sides.

[tex]k = \frac{3}{10} [/tex]

Therefor, the answer is k = 3/10.

Answer:

angle 1 = 51 degrees

angle 2 = 18 degrees

angle 3 = 123 degrees

angle 4 = 39 degrees

Step-by-step explanation:

angle 2 = 90-72 = 18

angle 3 = 180 - 57 = 123

angle 4 = 180 - 123 - 18 = 39

angle 1 = 90 - 39 = 51

Answer:

0.925 or 92.5%

Step-by-step explanation:

y=a(1-b)^x

decay factor is 1-b <- and the part we care about

b is 7.5%=0.075

1-0.075

=0.925

I'm a little rusty on exponential rates, but I hope this helps!

The decay factor for the car will be equal to 0.925 or 92.5%

Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied. Since 2 is the "base" and 5 is the "exponent," it can be written as 2 x 2x 2 x 2=25 for the number 32. This phrase should be understood as "two to the fifth power."

Given that Ed's new car has a value of $23,500, it is expected to depreciate at a rate of 7.5% per year.

The decay factor will be calculated as,

[tex]y=a(1-b)^x[/tex]

b is 7.5%=0.075

Decay factor = 1-0.075

Decay factor = 0.925

The total cost of the tablet is $840

Step-by-step explanation:

Here, we want to calculate the total cost

Let the total cost be $x

From the ratio, the total ratio is 3 + 4 + 1 = 8

so,;

3/8 * x = 315

3x = 8 * 315

x = 8/3 * 315

x = 8 * 103

x = 840

Answer:

x= -3

Step-by-step explanation:

-5x+3=18

-3 on both sides

-5x=15

divide by -5 on both sides

x= -3

Answer:

X= -3

Step-by-step explanation:

-5x+3=18 subtract 3 from both sides this removes the +3 from the left side and makes the 18 into 15

-5x=15 Divide both sides by -5

x=-3

Answer:

x = 60°

y = 72°

z = 48°

Step-by-step explanation:

x = 180 - p = 180 - 120 = 60

Since y;z = 3:2 ,   2y = 3z  or z = 2y/3

Now, x + y + z = 180

60 + y + 2y/3 = 180     Multiply thru by 3 to remove the fraction

180 + 3y + 2y = 540

180 + 5y = 540

5y = 360

y = 72

z = 2(72)/3 = 48

Check:  60 + 72 + 48 = 180

Answer:

x = 3√7

Step-by-step explanation:

The Pythagorean theorem states that in a right triangle, the sum of the legs squared and added together is equal to the hypotenuse (the longest side and the one across the 90° angle)

If the legs are a and b, respectfully, and the hypotenuse is c, the equation would be:

a² + b² = c²

Let's apply this to the problem given.

9² + x² = 12²

Simplify.

81 + x² = 144

Subtract 81 from both sides.

x² = 63

Take the square root.

√(x²) = √63 = √(9 * 7) = √(3² * 7)

x = 3√7

Check the answer.

9² + (3√7)² = 12²

81 + 9 * 7 = 144

81 + 63 = 144

144 = 144

Thus, the answer is correct.

I hope this helps! Feel free to ask any questions! :)

Answer:

Step-by-step explanation:

Answer:

a = 10.36m

B = 47.7º

C = 90º

Step-by-step explanation:

we know the angle of A so we do the sin of A; Spoiler: its 0.67

0.67 = a / 15.4

0.67 * 15.4 = a

a = 10.36

----------

B = 90 - 42.3 = 47.7º

Answer:

x = 4

y = 13

Step-by-step explanation:

x + y = 17

y = 2x + 5

substitute for y:

x + (2x + 5) = 17

reduce:

3x + 5 = 17

subtract 5 from each side:

3x = 12

divide both sides by 3:

x = 4

y = 2(4) + 5

y = 13

Answer:

A set is continuos if the values of the set can be any value in the given ranges

A set is discrete if the values of the set are finite and separate.

Than:

a) The weight of a puppy.

The weight of a puppy can be any value between 0 kg and a given maximum weight, then this is a continuous set.

b) The number of puppies in a litter.

Here we can have only whole numbers, for example, we can not have 7.34321 puppies in the litter, so this is a discrete set.

c) A person's temperature.

Temperature can be any value in a given range, so this is a continuous set.

d) The dress sizes of women.

Normally, there is a given set of dress sizes like s, l, xl, etc.

So in general, this is a discrete set. (While the actual "size" of a dress can take a lot more values than those ones, but this still is a discrete set)

Answer:

120

Step-by-step explanation:

First we can find the value of each exterior angle

The sum  of the exterior angles is 360

because a hexagon has 6 congruent exterior angles we divide 360 by 6

360/6=60 so each exterior angle is equal to 60 degrees

the exterior angle and interior angles of any regular polygon are supplementary angles ( meaning the sum of the two is 180) so to calculate the interior angle we subtract 60 from 180

180-60=120 so each measure of the interior angle of a hexagon is 120 degrees

Answer: 1620 gallons of water

Step-by-step explanation:

Let the water that is in the tank when the tank is at full capacity be represented by x.

Therefore, 40% of x = 648

40% × x = 648

40/100 × x = 648

0.4 × x = 648

0.4x = 648

x = 648/0.4

x = 1620

The answer is 1620 gallons

Step-by-step explanation:

Since we are not asked what to find, we can as well  look for the volume of the cone.

Find the diagram of the cone attached

Volume of the cone = 1/3πr²h

h is the height of the cone

r is the radius of the cone

Volume of the cone = 1/3π(5)²(5)

Volume of the cone= 1/3π(125)

Volume of the cone = 125π/3

Volume of the cone = 41.67πunits³
