Answer:

81 is a perfect square

18 isn't a perfect square

50 isn't a perfect square

32 isn't a perfect square

Step-by-step explanation:

Numbers whose square roots are whole numbers, or more accurately positive integers are called perfect root

Example 7×7=49

Adding the score of each round, Connor's current score is of -11 points.

To find the sum of two negative numbers, we keep the signal and add numbers.

For each round, Connor's scores are given as follows:

The combined score is the sum of each score, hence:

C = -5 + (-6) = -5 - 6 = -(5 + 6) = -11.

Connor's current score is of -11 points.

Answer:

0.9 in the context represent the price of the ginger

It is called decreasing factor for the function because it decreases the price of the ginger

Step-by-step explanation:

Original price of fresh ginger ale = G

Coupon = 10% off

The actual price paid = 100% - 10% of G

= 90% of G

= 90/100 × G

= 0.9 × G

Answer:

Step-by-step explanation:

interior angle =(n-2)180

=(4-2)*180

=360

360=164+71+24+x

360=260+x

x=360-260

x=100

Answer:

Step-by-step explanation:

Since angles in quadrilateral (4-sided shape) add up to 360 degrees

therefore,

360 = 164 + 71 + 25 + x

360 = 260 + x

subtract 260 from both sides

360-260 = 260-260 + x

100 = x

Explanation:

Add -3 to each term to get the next term. This is the same as subtracting 3 from each term. In this case, the common difference is d = -3.

The first term is a = 20

---------

The nth term formula for the arithmetic sequence is

a(n) = a+d(n-1)

a(n) = 20+(-3)(n-1)

a(n) = 20-3n+3

a(n) = -3n+23

If we plug in n = 1, we would get a(n) = 20. Plug in n = 2 to get a(n) = 17. And so on. This helps confirm we have the correct nth term formula.

The solution is, $210 does he have to spend after paying his bills.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given that,

Drake’s monthly outlay include a $70 phone bill and a $120 car assuming he makes $400 a month,

i.e. we get,

Drake’s monthly outlay include a $70 phone bill and a $120 car.

so, total spend = $ 120 + 70

                         = $190

now, we have to find how much does he have to spend after paying his bills.

so, we have to subtract 190 from 400

i.e. 400 - 190

=210

Hence, $210 does he have to spend after paying his bills.

Answer: 5 inches

Step-by-step explanation:

The volume of a cylinder is equal to pi*radius^2*height.

We can replace the height with 12 inches and the volume with 942 cubic inches.

Therefore, 942 in^3 = pi*radius^2*12 inches

We can divide both sides by 12:

pi*radius^2 = 78.5 inches^2

We can divide both sides by pi:

Radius^2 = About 24.99 inches^2

We can square both sides:

Radius approximately equals 5 inches.

Answer:

y=x+1

Step-by-step explanation:

The slope of the equation is 1, you can try the rise over run method or picking 2 points and subtracting them for example 2,3 and 3,4

2,3-3-4=1,1. The y-intercept is 1 because that is the point where the line crosses the y axis.

Answer:

Slope intercept form:

y = mx + b

Where 'y' is the independent variable and 'x' is the dependent variable.

'm' represents the slope(rise/run), and 'b' represents the y-intercept(where the line meets the y-axis).

If we look at this graph, we can see the line meets the y-axis at 1. So 1, will be our y - intercept.

We can also see, that from the point 1, it rises 1 and goes over 1. So 1, will be our slope as well.

To double check this, we select two fixed points on this graph and subtract the y-coordinates from each other and divide the result of that by the x-coordinates subtracted from each other.

y2(second y-coordinate) - y1(first y-coordinate)

_____________________________________

x2(second x-coordinate) - x1(first x-coordinate)

We pick the two points to be, (1,2) and (2,3).

 3 - 2              1

______ = _______, which is equal to 1, so 1 is the slope.

 2 - 1               1

Now we insert these values into our slope intercept form equation:-

y = mx + b

y = 1x + 1 or y = x + 1.

Where 1 is the slope, and the y-intercept is 1.

Answer:

y = 2x + 8

Step-by-step explanation:

the equation of a line in slope-intercept form is.

y = mx+b

where m is the slope and b the y-intercept

to calculate m use the gradient formula

m = (y2−y1 ) / (x2−x1)

let (x1,y1)=(-6,-4) and (x2,y2)=(-4,0)

m = (0 - (-4)) / (-4 - (-6) = 2

y = 2x+b←is the partial equation

to find b substitute either of the 2 given points

into the partial equation

using (-6, -4) then

-4 = -12+b⇒b=8

y = 2x + 8←is the equation of line

Given :

Population of country in 2006 , P = 300 million.

Consumption of fruit juice in 2006 by while population, C = 1.85 billion.

To Find :

The average number of gallons of fruit juice consumed per person in the country in​ 2006.

Solution :

We know, 1 billion = 1000 million.

C = 1.85 billion = 1850 million.

Now, average umber of gallons of fruit juice consumed per person in the country in​ 2006 is :

[tex]c =\dfrac{C}{P}\\\\c=\dfrac{1850}{300}\ gallons/person\\\\c=6.17 \ gallons/person[/tex]

a) Probability of getting a medium shirt for the player ≈ 0.0385

b) Probability of getting a medium shirt for the player's sister ≈ 0.0385

c) Probability of getting a medium shirt for both the player and his sister ≈ 0.00148225

d) Probability of getting either a medium, large, or extra-large shirt ≈ 0.0385.

Here, we have,

To find the probability of each event, we first need to determine the total number of shirts in the box and the number of shirts that satisfy each event.

a) Probability of getting a medium shirt for the player:

Total number of medium shirts = 6

Number of medium shirts needed for the player = 1

Probability = (Number of medium shirts needed) / (Total number of shirts) = 1 / (6 + 10 + 10) = 1 / 26 ≈ 0.0385

b) Probability of getting a medium shirt for the player's sister:

Total number of medium shirts = 6

Number of medium shirts needed for the player's sister = 1

Probability = (Number of medium shirts needed) / (Total number of shirts) = 1 / (6 + 10 + 10) = 1 / 26 ≈ 0.0385

c) Probability of getting a medium shirt for both the player and his sister:

Since the two events are independent (one person getting a medium shirt does not affect the other's chance of getting a medium shirt), we can multiply the probabilities of each event:

Probability = Probability of player getting a medium shirt * Probability of player's sister getting a medium shirt ≈ 0.0385 * 0.0385 ≈ 0.00148225

d) Probability of getting either a medium, large, or extra-large shirt:

Total number of medium, large, and extra-large shirts = 6 + 10 + 10 = 26

Number of shirts needed = 1 (for the player or his sister)

Probability = (Number of shirts needed) / (Total number of shirts) = 1 / 26 ≈ 0.0385

To summarize:

a) Probability of getting a medium shirt for the player ≈ 0.0385

b) Probability of getting a medium shirt for the player's sister ≈ 0.0385

c) Probability of getting a medium shirt for both the player and his sister ≈ 0.00148225

d) Probability of getting either a medium, large, or extra-large shirt ≈ 0.0385.
