On solving the linear equation, There are in total 24 unshaded squares and 16 shaded squares.

Ax+By=C is the usual form for two-variable linear equations. A typical form linear equation is, for instance, 2x+3y=5. When an equation is provided in this format, finding both intercepts is rather simple (x and y).

squares, where x= number of squares

2x = shaded squares

Number of unshaded squares = 3x.

This is due to the fact that there are 3 times as many unshaded squares as there are shaded squares (2 times more unshaded = 3*). (shaded)

Overall, there are 40 squares (5 * 8), therefore 40 total squares—shaded and unshaded—are present.

2x+3x = 40

5x = 40

x = 40/5

x = 8

There are 3×8 = 24 unshaded squares

8×2 = 16 shaded squares in all.

Therefore, you may shade in 8 squares whatever you choose.

Answer:

y = 1/3x - 3

Answer:

  -19/60

Step-by-step explanation:

You want the rational number halfway between -1/3 and -3/10.

The average of two numbers is the number halfway between them. It is their sum, divided by two.

Effectively, you are being asked for the average of -1/3 and -3/10.

  [tex]\text{average }=\left(-\dfrac{1}{3}-\dfrac{3}{10}\right)\times\dfrac{1}{2}=-\dfrac{1\cdot10+3\cdot3}{3\cdot10\cdot2}=\boxed{-\dfrac{19}{60}}[/tex]

Reroll 6’s = 26 times

Failed turn on 6's = 21 times

If the initial roll is a 6, the question enters an unending cycle. Reroll till it isn't 6, or simply treat it as a failed round since the roll was legal and didn't result in a pair of twos.

The likelihood of each number being rolled is the same.

If the first roll is n, there are (6 - n) options for the greater number. Thus p = 1/(6 - n) for a specific (possible) result such as n + 2.

Then,

p(2 apart) = p(1, then 3) + p(2, then 4) + p(3, then 5) + p(4, then 6)

Reroll 6’s:

p(2 apart) = (1/5)(1/5) + (1/5)(1/4) + (1/5)(1/3) + (1/5)(1/2)

p(2 apart) = (1/5)(1/5 + 1/4 + 1/3 + 1/2) = 0.25666…

So for 100 times, we will get 26 times 2 apart

Failed turn on 6:

p(2 apart) = (1/6)(1/5) + (1/6)(1/4) + (1/6)(1/3) + (1/6)(1/2)

p(2 apart) = (1/6)(1/5 + 1/4 + 1/3 + 1/2) = 0.2138

So for 100 times, we will get 21 times 2 apart

The graph cannot be used to complete the table of values and the missing value of a is 7

The graph represents the given parameter

There are no points plotted on the graph

This means that the table of values cannot be completed

Hence, the graph cannot be used to complete the table of values

The table represents the given parameter

On the table, we have the following points

(x, y) = (0, -2), (2, 4), (3, a)

Also, we have that the points fall on a line

This means that the points make a linear equation

By analyzing the x and y values, we can see that

As x increases by 2, y increases by 6

This means that as x increases by 1, y increases by 3

So, when x = 3, the value of y is

y = 4 + 3

Evaluate

y  = 7

Rewrite as

a= 7

Hence, the missing value of a is 7

Answer:b

Step-by-step explanation:

The area of circle S will be 50.24 mm². Then the correct option is A.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of circle S is half the radius of circle L.

Let 'r₁' be the radius of circle S and 'r₂' be the radius of circle L. Then the equation is given as

r₁ = r₂ / 2

The radius of circle L is 8 millimeters. Then the radius of the circle S is calculated as,

r₁ = 8 / 2

r₁ = 4 mm

The area of the circle S is calculated as,

A = πr₁²

A = 3.14 x (4)²

A = 50.24 mm²

The range of the circle S is 4 mm. Then the region of the circle S will be 50.24 mm². Then the right choice is A.

Answer:

Step-by-step explanation:

Using translation concepts, we have that:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The parent absolute value function is defined by:

f(x) = |x|.

And has vertex at (0,0).

After a translation, the absolute value function is given by:

g(x) = |a(x - h)| + k.

The vertex is at: (h, k).

In this problem, the function is:

g(x) = |-0.5(x + 3)| - 1.

Recall the Weierstrass product definition of the gamma function,

[tex]\displaystyle \frac1{\Gamma(z)} = ze^{\gamma z} \prod_{n=1}^\infty \left(1+\frac zn\right) e^{-z/n}[/tex]

from which we can obtain the log-gamma (i.e. logarithm of gamma) function,

Along with the definition of the Riemann zeta function,

The location rotates 24.9 miles in 1 day

It is a method in which one finds the value of a unit from the value of a number of units and the value of a number of units from the value of a  unit.

In the unit method, we always count the value of a unit or quantity first, and then we calculate the value of more or less quantities. This is why this method is called the unitary method.

Earth equator moves 2.075 miles in 2 hours, We need to find how far does this location rotate in 1 day

Using Unitary Method

1 hour = 2.075/2 mile

1 hour = 1.0375 mile

Step-by-step explanation:

There are 18 more servers than cooks at Bruno's burgers when the ratio is 2 : 5.

We are given that the ratio of cook to server in Bruno's Burgers is given by 2 : 5

We also know that the total number of cooks and servers = 42

Now, let number of cooks be 2 x and the number of servers be 5 x

So, ATQ, we get that:

2 x + 5 x = 42

7 x = 42

x = 42 / 7

x = 6

Number of cooks = 2 x = 2 (6) = 12

Number of servers = 5 x = 5 (6) = 30.

Difference = 30 - 12 = 18

Therefore, we get that, there are 18 more servers than cooks at Bruno's burgers when the ratio is given as 2 : 5.

Answer:

x = 11

Step-by-step explanation:

If given angles m∠A = (3x +22)° and m∠B= (7x – 22)°, the value of x is 11.

Vertical angles are formed by the intersection of two lines. They are opposite to each other and have equal measures. In this case, we have two vertical angles, ∠A and ∠B.

Given that m∠A = (3x + 22)° and m∠B = (7x - 22)°, we can set up an equation based on the fact that vertical angles are equal.

(3x + 22)° = (7x - 22)°

To solve for x, we can simplify the equation:

3x + 22 = 7x - 22

Next, we can isolate the variable x by moving the terms containing x to one side of the equation:

3x - 7x = -22 - 22

-4x = -44

Finally, we divide both sides of the equation by -4 to solve for x:

x = -44 / -4

x = 11
