HELPPP PLEASEE SIMPIFY THIS EXPRESSION !!!!!

Answer:

z = 188

Step-by-step explanation:

1. 10/13 = 8 - 2z/52 (simplify - 2z/52)

10/13 = 8 (- 1/26)*z

2. 10/13 = (- 1/26)*z + 8 (flip for ease in solving)

(- 1/26)*z + 8 = 10/13

3. (- 1/26)*z + 8 = 10/13 (inverse: subtract 8 from each side to isolate variable z)

(- 1/26)*z = 10/13 - (8*13)/(1*13)  (common denominator needed for add/subtract)

(- 1/26)*z = - 94/13 (simplify)

4. (- 1/26)*z = - 94/13 (inverse: multiply both sides by -26/1 to isolate variable z)

Answer:

188

Answer:

square 20 has 44 green squares

square 21 has 45 green squares

Step-by-step explanation:

To solve the problem, we need to observe the cases, and determine/define a rule for each case (odd number of sides, or even number of sides).

For square one, we note that the centre square is shared by two diagonals, so we saved one square from the two diagonals.

The side length is 3 for square 1, 4 for square 2, and so on.

Let

n= square number (1, 2,3...)

L = side length (3,4,5...)

G1(n) = function that gives the number of green squares for square n, n=odd

G2(n) = function that gives the number of green squares for square n, n=even

side length, L=n+2   ................(1)

G1(n) = twice the side length less one, as discussed above

G1(n) = 2L-1       now substitute L=n+2

G1(n) = 2(n+2) -1    simplify

G1(n) = 2n + 3

Check:

for n=1, square 1 has 2*1+3 = 5 green squares ... checks

for n=3, square 3 has 2*3+3 = 9... checks

for n=5, square 5 has 2*5+3 = 13 ....checks

For even squares, it is even easier, because

G2(n) = 2L = 2(n+2)

check:

for n=2, square 2 has 2(2+2) = 8 green squares........checks

for n=4, square 4 has 2(4+2) = 12 green squares........checks.

Fincally, we apply our formula to n=20 and n=21

square 20 : G2(20) = 2(n+2) = 2(20+2) = 44 green quars

square 21 : G1(21) = 2n+3 = 2(21)+3 = 45 green squares

Answer:

Mean: 8

Median: 6

Mode: 6

Range: 7

Step-by-step explanation:

Mean: 5+6+6+11+12=40 Then. 5 numbers, so 40 divided by 5=8.

Median: The middle number which is 6

Mode: The most occurring number which is 6.

Range: Highest number(12)-lowest number (5)=7

Answer: median= 1.05

Step-by-step explanation: mean: 8

mode: 6

Answer:

Step-by-step explanation:

Displacement:  d(t) = 2t^3 + 5t^2 - 3

Velocity:  (d/dt)(2t^3 + 5t^2 - 3) = v(t) = 6t^2 + 10t

Acceleration:  (d/dt)(d/dt)(6t^2 + 10t) = a(t) = 12t + 10

At time t = 4hr,

d(4) = [128 + 80 - 3] km = 205 km

v(4) = [96 + 40] km/hr  =  136 km/hr

a(4) = [48 + 10] km per hour squared  = 58 km over hours squared

Answer:

Step-by-step explanation:

hello,

for t = 4 hours

[tex]d(4)=24^3+54^2-3=2*64+5*80-3=128+80-3=205[/tex]

this is 205 km

d is differentiable and

[tex]d'(t)=6t^2+10t[/tex]

and

[tex]d'(4)=6*4^2+10*4=6*16+40=96+40=136[/tex]

this is 136 km/h

d' is differentiable and

[tex]d''(t)=12t+10[/tex]

and

[tex]d''(4)=12*4+10=48+10=58[/tex]

this is [tex]58 \ km/h^2[/tex]

Answer: The center is (-7, 4) and the radius is 7.

Step-by-step explanation:

The equation for a circle usually is:

(x - a)^2 + (y - b)^2 = R^2

where R is the radius, and (a, b) is the center of the circle.

I guess that the equation in this case is:

(x + 7)^2 + (y - 4)^2 = 49

then, in this case we have:

a = -7 and b = 4, then (a, b) = (-7, 4)

this means that the center of our circle is in the point (-7, 4)

and we know that:

R^2 = 49

R = √49 = 7

Then the radius is equal to 7.

Answer:

For each additional pound, the price increases $1.50.

Step-by-step explanation:

Lets find the slope of the graph of othe given data.

Let x be the weight of pumpkin in pounds

Let y be the price of the pumpkin in dollars.

For 4 pound pumpkin the price is 6 dollars, so first point is (4,6)

For 8 pound pumpkin the price is 12 dollars, so first point is (8,12)

Find the slope between these points

m = y₂ - y₁ / x₂ - x₁

m = 12 - 6 / 8 -4

m = 6/4

m = 1.5

Which means that for every pound increase in weight, the price of pumpkin increases by 1.5 dollars

Answer:

Range remains the same.

Step-by-step explanation:

(1,3),(-2,1),(-5,-1) and (1,-2)

The range is { -2 ≤ y≤ 3 } .

Transformation is changing the graph to a new one by Rotation, Reflection, Translation, and Dilation.

Reflection is to create a mirror image of the coordinate or the figure.

After reflection along any axis, the coordinate of the other axis changes to its additive inverse.

(x,y) ----> when reflected along y axis ----> ( -x , y)

The domain is all the values a function can have as input and the range is all the values that a function can have.

The original coordinate changes to  (-1,3),(2,1),(5,-1)and(-1,-2).

When reflected along the y-axis, the coordinates of the x-axis change and there is no change in the y-axis.

So the value of the domain changes while the range remains the same.

The range is { -2 ≤y≤3}

Step-by-step explanation:

Polynomials are closed under subtraction and multiplication because any subtraction or multiplication of polynomials gives as result another polynomial.

As can be seen in option D, polynomials aren't closed under division because not every division between polynomials gives as result another polynomial.

Answer: 307.8 yards

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.  

Sin α = opposite side / hypotenuse  

Where α is the angle of depression of the boat looking down to a submarine, the hypotenuse is the distance from the boat to the submarine, and the opposite side (x) is the distance between the submarine and the sea level:

Replacing with the values given:  

Sin 38 = x/ 500

Solving for x  

Sin 38 (500) =x  

x= 307.8 yards

D:  Acute triangle

Step-by-step explanation:

First check whether this could be a right triangle.  Using the Pythagorean Theorem, we get:

5^2 + 6^2 = ? = 7^2      This equation is not true, and therefore the triangle is not a right triangle.

The side lengths 5, 6 and 7 are very close to one another, and so the triangle must have essentially similar interior angles, which means that all three angles are acute.  Answer D is correct:  This is an acute triangle.

Answer:

x >  -22/9

Step-by-step explanation:

-9x/11 < 2 (add 7 to both sides)

-9x < 22  (multiply both sides by 11)

x > 22/-9 (Switch the sign because you are dividing by a negative number)

Answer:

x > -22/9

Step-by-step explanation:

- 9x/11 - 7 < -5

Add 7 to both sides.

- 9x/11 - 7 + 7 < -5 + 7

- 9x/11 < 2

Multiply both sides by 11.

-9x/11 × 11  < 2 × 11

-9x < 22

Divide both sides by -9, reverse sign.

-9x/-9 < 22/-9

x > -22/9

Answer:

2775.9  

Step-by-step explanation:

options are

A) 578

B) 2775.9

C) 134.591

D) 31.757

Value of digit 5 in 4.59 is 0.5 as is is at tenth place after decimal

0.5 = 5/10

ten times of this value = 5/10*10 = 5

Thus, 5 is the value, and hence the number which we require should be at unit place of the required number.

In the given question

A) 578

here 5 is at hundredth place

other way to represent is is 500+70+8

B) 2775.9

here 5 is unit place and is correct option

it can be represented as

2000+ 700+ 70+ 7 + 9/10

c)C) 134.591

here 5 is tenth place after decimal

it can be represented as

100+ 30+ 5 + 5/10+9/100 + 1/1000

d)31.757

here 5 is hundredth place after decimal

it can be represented as

30+ 1 + 7/10+5/100 + 7/1000\

Hence, 2775.9  is correct choice.

Answer:

16.492422502 units or 4√17 units

Step-by-step explanation:

The Perimeter of a Square can be defined as the Addition of it's 4 sides or the Multiplication of 4 and one of its sides.

This means,

The perimeter of square = a + b + c + d

or

4 × any of the sides because the sides of a square are equal to one another.

In the above question, we are given vertices at A(-1,3) B(0,7) C(4,6) and D(3,2)

The formula to solve for this is

√(x2 - x1)² + (y2 - y1)² when you have vertices: (x1 , y1 ) and (x2 , y2)

For Side AB: A(-1,3), B(0,7)

= √(x2 - x1)² + (y2 - y1)²

= √(0- (-1))² + (7 - 3)² = √1² + 4² = √1 + 16 = √17

For Side BC: B(0,7), C(4,6)

√(x2 - x1)² + (y2 - y1)²

= √(4 - 0)² + (6 - 7)² = √4² + 1² = √16 + 1 = √17

For Side AD : A(-1,3), D(3,2)

= √(x2 - x1)² + (y2 - y1)²

= √(3- (-1))² + (2 - 3)² = √4² + (-1)² = √16 + 1= √17

For Side CD: C(4,6), D(3,2)

= √(x2 - x1)² + (y2 - y1)²

= √(3 - 4)² + (6 - 2)² = √-1² + 4² = √1 + 16 = √17

From the above calculations we can side that sides AB = BC = AC = CD

Hence the perimeter of square ABCD can be calculated as 4 × √17 or √17 + √17 + √17 + √17

= 16.492422502 units or 4√17 units

Answer:

Step-by-step explanation:

c = $30.24

g = 16

Divide c/g

Answer:

g gallon = $1.89 g

Step-by-step explanation:

Gallon = g

16 gallons = 16 g

Cost = $30.24

16 gallons = $30.24

1 gallon = $30.24/16

1 gallon = $1.89

g gallon = $1.89 g
