Answer:

40

Step-by-step explanation:

1. Plug in the given value for n

6(5) + (5)2

2. Solve using PEMDAS

(I'm not sure if the 2 after the n is supposed to be squared, but if it was n^2 then the correct answer would be 55, I think)

30 + 10 = 40

Therefore, the answer is 40

2.4 meters separate the prairie dog from (0,0) and the ground level.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

To find the distance x from (0,0) where the prairie dog reaches ground level, we need to find the point on the graph where y=0.

Substitute y=0 into the equation:

0 = x^2 - 2.4x

Factor out x:

0 = x(x - 2.4)

So either x = 0 or x - 2.4 = 0.

If x = 0, the prairie dog is still underground, so we take x = 2.4 as the distance from (0,0) where the prairie dog reaches ground level.

Therefore, the prairie dog reaches the ground level at a distance of 2.4 meters from (0,0).

Answer:

55 degrees

Step-by-step explanation:

All the angles of a triangle should add up to 180 degrees.

So, if you add angles 1 and 2 together and subtract them from 180 it will result in the unknown angle.

35+ 90 + x = 180

125 + x = 180

x = 55

b) 2 was not multiplied by 5

Step-by-step explanation:

Correct answer: 2x + 10

Answer:

b

Step-by-step explanation:

Given

12x+ 8 = 10x + 18 ( subtract 10x from both sides )

2x + 8 = 18 ( subtract 8 from both sides )

2x = 10  ( divide both sides by 2 )

x = 5

The equation has one solution

Answer:

B

Step-by-step explanation:

verification

12 x 5 + 8 = 10 x 5 + 18

68= 68

since the answer is 68

it is the only one answer that you can get

Answer:

y = 2

Step-by-step explanation:

The way you solve this is you transform it until one side of the equation is just "y"

3y + 2 = 8   ;    subtract 2 from both sides

3y = 6   ;     divide both sides by 3

y = 2

Answer:1/3

Step-by-step explanation:1/3 is the simplified fraction for 6/18 by using the GCD or HCF method. Thus, 1/3 is the simplified fraction for 6/18 by using the prime factorization method.

Answer:

6/18=1/3

Step-by-step explanation:

here so the 6 is common with 18 and so that is 3

Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)​

Answer:

GCF = 5x² + 8x - 9

Step-by-step explanation:

The given polynomial is;

10x³ + 16x² - 18x

First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.

The greatest number is 2.

Secondly let's inspect the variables to see what we can factor out.

They all contain x. Thus, x is a factor.

Thus, we will divide each term by 2x to obtain the GCF of the polynomial.

GCF = (10x³/2x) + (16x²/2x) - (18x/2x)

GCF = 5x² + 8x - 9

Answer:

5: independent, 6:independent, 7:independent, 8:dependent, 9:dependent

Step-by-step explanation:

5 is independent because the first roll of the die does nothing to affect the second.

6 is independent because the first flip of the coin does nothing to affect the second

7 is independent because the first draw from the bag does nothing to impact the second, if they didn't place a marble back then it would become dependent.

8 is dependent because by keeping the first marble you change the odds for the second draw. The second draw depends on the first.

9 is dependent because there is a set amount of names placed into this raffle. Say to start you have 12. That means you have a 1/12 chance of being chosen. Once your name is drawn it goes up to a 1/11 chance. The first action directly impacts the second making it dependent.

I just did it on EDG, got it wrong so i could give you the answer XD

The likelihood that a randomly chosen consumer on plan B would text on the phone the most frequently is 13/23.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

According to the given data,

Number of customers on plan B = 13 + 10 = 23

Number of customers on plan B who text = 13

P(text|plan B) = P(text and plan B) / P(plan B),

where P(text and plan B) is the probability of a customer being on plan B and texting, and P(plan B) is the probability of a customer being on plan B, can be used to calculate the likelihood that a randomly chosen customer on plan B will text the most.

So,

P(text|plan B) = 13/23

Therefore, the probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23.

Answer:

donuts:  $5.00

croissants: $9.00

Step-by-step explanation:

c - croissants

d - donuts

(1) 3d + 5c = 60        

(2) 4d + 5c = 65

solve for 5c in equation (1)

5c = 60 -3d

substitute 5c = 60-3d into (2)

4d + (60 - 3d) = 65

d + 60 = 65

d = 5      

to find c substitute d = 5 into (1)

3(5) + 5(c) = 60

15 + 5c = 60

5c = 45

c = 9

Answer:

A 2 ounce bag costs $1.2.

Step-by-step explanation:

With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.

6 ounce bag → 3.60

2 ounce bag →   x

x=(2*3.60)/6

x=7.20/6

x=1.2

According to this, the answer is that a 2 ounce bag costs $1.2.

Answer:

A) which graph represents the equation x^2 + y^2 = 2.25?

First, the general equation for a circle can be written as:

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

This is a circle of radius R centered in the point (a, b).

Then we can rewrite our equation as:

(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2

Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5

Then we can see that the correct one is graph C.

b) Now we want to solve the system:

x^2 + y^2 = 2.25

y - x = 1

graphically.

To do it we need to graph both equations and see in which points do they intersect.

We already have the first equation graphed, so we only need to also graph the linear equation:

y - x = 1

y = 1 + x

An example of this can be seen in the graph below:

There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)

Answer:

A. Line r intersects line p

Step-by-step explanation:

to find the second graph multiply the slope of line p by -10

slope is 1/5 or 0.2

So,

0.2 * -10 = -2

slope of second line is -2
