Answer:

It's answer is 2....

...

Answer:

3x + 4/2 + 5 ( x - 3 ) = 3/1

or, 3x + 4/2 + 5 x - 15 = 3/1

or, 3x + 5x - 15 = 3/1 -4/2

or, 8x - 15 = 6-2/2

or, 8x -15 = 4/2

or, 8x = 2 +15

or, x = 17/8

or, x = 2.125

hope it is helpful to you ☺️

Answer:19 would be 79 because you would do 8 plus itself 7 times which would be like 8*7 which is 56 so 56+23 is 79 im not sure what 18 is because im not sure if its x*2 or x^2 but 20 would just be 38/4 which is 9.5 so the answer for 20 is that Becca makes $9.5 dollars an hour.

Answer:

k =0.156

Step-by-step explanation:

According to the Question,

We Have To apply Just some Basic Properties of log here.

[tex]log_{3}4 = log_{1/27}k\\\frac{log_{}4 }{log_{}3 } = \frac{log_{}k }{log_{}1/27 }\\\\\frac{log_{}4 }{log_{}3 } = \frac{log_{}k }{log_{}1-log_{27} }\\\\frac{log_{}4 }{log_{}3 } = \frac{log_{}k }{0-3*0.4771} }\\\[/tex]

0.620/0.4771 = ㏒k / -1.4313

㏒k = -1.86

k = anti㏒(-1.86)

k =0.156

Answer:

15

Step-by-step explanation:

525/4 ÷ 35/4

=525/4 x 4/35

=525/35

=105/7

=15/1

=15

Answer:

So 1) x²-2x-8

= x(x-2-8/x)

2) y²-13y+42

= y(y-13+42/y)

3) m²-6m-7

= m(m-6-7/m)

Given:

In the first year, the car will decrease in value by 25%.

The cost of a car is Rs. 200,000.

To find:

The worth of the car after 1 year.

Solution:

The cost of a car is Rs. 200,000 and in the first year the car will decrease in value by 25%. So, the worth of the car after 1 year is:

[tex]Worth=200000-\dfrac{25}{100}\times 200000[/tex]

[tex]Worth=200000-\dfrac{1}{4}\times 200000[/tex]

[tex]Worth=200000-50000[/tex]

[tex]Worth=150000[/tex]

Therefore, the worth of the car after 1 year is Rs. 150,000.

Hello!

10*17 = > 170 cm²

(3,14 * 8)/4 =>6,28cm²

170 + 6,28 => 176,28cm²

Answer:

182.56

Step-by-step explanation:

Area of the rectangle = 10 * 17 = 170cm^2

Area of Circle = 8 * 2 * [tex]\pi[/tex] * 1/4

=> 12.56

=> 170 + 12.56

=> 182.56 is the area

Answer:

07-7-7

Step-by-step explanation:

Answer:

675 sq feet

Step-by-step explanation:

Radius =15ft

Area = 3(15)^2

= 3(15)(15)

= 3(225)

=675 sq ft

Answer:

675

Step-by-step explanation:

We square r first, so 15 ^ 2 = 225.

Then multiply by pi, which is 3 for this problem. 225 x 3 = 675.

Therefore, the answer is 675.

Answer:40: the amount in dollars that sam owes Daniel. 12: the amount in dollars that sam earns per hour, y variable: the amount in dollars that sam has after paying back Daniel, x variable: the number of hours Sam works at the airport.

Step-by-step explanation:

Answer:

x variable =  represents the number of hours Sam works at the airport

y variable = represents the amount in dollars that Sam has after paying Daniel 

12 = is the amount in dollars that Sam earns per hour

40 = is the amount in dollars Sam owes Daniel

√9 is rational and √3 irrational number

Answer:

Step-by-step explanation:

First, let's find the area of the triangle. The Area of a triangle can be modeled as

b x h x 1/2; base = 6 and the height equals 8. 6x8=48 then don't forget to divide by 2. 48/2= 24

To find the area of a half-circle, you first need to find the area of the whole circle. Whole circle area equation = r^2 times pi. The diameter is 8 and the radius is 1/2 times the diameter, therefore the radius = 4. 4^2= 16

16pi= approximately 50.24

50.24/2= 25.12

25.12 + 16 = 41.12

The area of the figure is approximately 41.12 ft^2

Hope this helps and please mark me brainliest, it really helps!

Answer:

49.12 ft²

Step-by-step explanation:

The compound figure includes both a right angled triangle and a semi-circle. To find the area of the figure, it is best to find the area of both shapes then add them.

Area of semi-circle = (πr²) ÷ 2

= (3.14 × 4 × 4) ÷ 2

= 50.24 ÷ 2

= 25.12 ft²

Area of triangle = [tex]\frac{1}{2}[/tex]bh

= [tex]\frac{1}{2}[/tex] × 6 × 8

= 24 ft²

Area of compound figure = Area of semi-circle + Area of triangle

= 25.12 + 24

= 49.12 ft²

Answer:

[tex]slop = \frac{2 - 1}{2 - 0} = \frac{1}{2} \\ for \: point \: x = 0 \: y = 1 \\ y - 1 = \frac{1}{2} \times (x - 0) \\ y = \frac{1}{2} x + 1[/tex]

Answer:

vertex = (- 2, - 4 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 4x ← is in standard form

with a = 1, b = 4, c = 0 , then

x = - [tex]\frac{4}{2}[/tex] = - 2

Substitute x = - 2 into the equation for corresponding value of y

y = (- 2)² + 4(- 2) = 4 - 8 = - 4

vertex = (- 2, - 4 )

Answer:

68% of the area

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this question:

By the Empirical Rule, 68% of the area is within 1 standard deviation of the mean.

Answer:

the correct answer is 68.27%

Step-by-step explanation:

Answer:

Geometric mean is the nth root of the product of n numbers

For two numbers it's the square root

for three numbers it's the cube root

for 4 numbers it's the fourth root

etc.

Answer: 72.6 cm

Step-by-step explanation:

Data: the length of the sides we know=13 cm, 16 cm 7.3 cm, 5.7 cm, 6.2 cm

The length of the side in the middle=x

The perimeter of the shape=x

Step one, Find the length of the missing side by adding then subtracting

5.7+6.2=11.9

16-11.9=4.1

x=4.1 cm

Reason: If you want to find the missing side, we know that the entire side down there is 16 cm so we just add 5.7 to 6.2 to get 11.9 and the amount of cm left after subtracting 11.9 from 16 will be the length(l) of the missing side.

Step two, add up all the sides

13+13+16+7.3+7.3+4.1+5.7+6.2=72.6

Reason: To find the perimiter of a shape, you add up all the sides and since we have all of the sides(some sides appear twice) we can just add them all together for the answer.

Also, don't forget the 'cm' in the answer

x=72.6 cm
