Find the distance between the points (
-
10,12) and (15,12).

Answers

The distance formula is:

[tex]d= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} [/tex]

We are given two points in the form (x,y), so plug in the values to the distance formula:

[tex]d= \sqrt{(-10-15)^2-(12-12)^2} [/tex]

Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:

[tex]d= \sqrt{(-25)^2} [/tex]

The square and square root cancel each other out leaving us with 25.

The answer is 25.

Toysrus is having a 38% off sale. If a backpack normally costs $22, how much will it cost on sale

Answers

it will be 13.64. it is bc 38% of 22 is 8.36 and 22-8.36=13.64

The backpack will cost $13.64 during the 38% off sale at Toysrus, calculated by subtracting the discount ($8.36) from the original price ($22).

To calculate the discount amount, we multiply the original price by the discount percentage:

$22 * 0.38 = $8.36

Now, to get the sale price, we subtract the discount amount from the original price:

$22 - $8.36 = $13.64

Therefore, the backpack will cost $13.64 on sale.

The table shows the number of boys and girls that have black, blonde, brown, or red hair color. What is the probability that a girl has black hair?

Answers

Answer:

O.25

Step-by-step explanation:

Trust me on this one the answer was in the comments :/

Final answer:

The probability of a girl having black hair is determined by dividing the number of girls who have black hair by the total number of girls. Without actual numbers from the table, a specific probability cannot be calculated.

Explanation:

To find the probability that a girl has black hair, we have to first know the total number of girls, and then the number of girls who have black hair. Probability is determined by dividing the number of desired outcomes by the total number of outcomes. So in this case, if we let 'G' denote the total number of girls and 'B' be the number of girls with black hair, the formula for the probability would be P(B) = B / G. Without the actual numbers from the table, we cannot calculate the specific probability.

Annie is planning a business meeting for her company. her budget is 1,325 for renting the meeting room at the local hotel and providing lunch. she expects 26 people to attend the meeting the room cost $270 which inequality show how to find the amount × Annie can spend for lunch on each person

Answers

$1325 - $270 = $1055

Annie has $1055 to spend on 26 lunches.

Let the cost of a lunch be x.

26x < 1055

x < $40.58

Answer: x < $40.58

Answer:

26x + 270 ≤ 1,325

Step-by-step explanation:

Suppose x be the amount ( in dollars ) of lunch of each person,

So, the cost of lunch for 26 people = 26x,

Also, the cost of meeting room = $ 270,

Thus, the total cost = total cost of lunch + meeting room cost

= 26x + 270,

According to the question,

The budget of meeting is $ 1,325,

That is, the total cost can not exceed to $ 1325,

[tex]\implies 26+270 \leq 1325[/tex]

Which is the required inequality that will used to find the cost of each lunch.

Find f. f ''(x) = 4 + 6x + 36x2, f(0) = 2, f (1) = 10

Answers

It has been a while since I have done differnetial equations but I think here you only need to integrate twice.
4 + 6x + 36x^2= 2*(2+3x+18x^2)

Integrate 2+3x+18x^2 to get 2x+3/2x^2+18/3x^3 +C = 2x +3/2x^2+6x^3 + C
Integrate again now this: 2x +3/2x^2+6x^3 + C to get x^2 + 1/2x^3+3/2x^4 +Cx +D
Now multiply by two (as I have taken out 2 earlier)
2x^2+x^3+3x^4+2Cx+D

Now use the initial conditions.
f(0)=2
D=2
f(1)=10
2+1+3+2C+2=10

if we use the two terms given, setting a12 as starting term and a45 as the end term an.

170 = 38 + 33d
170 - 38 = 33d
132 = 33d

132/33 = d
This is the common difference, use it to find the first term.

38 = a0 + (132/33)(12-1)
38 = a0 + (132/33)(11)
38 = a0 + 132/3
38 - 132/3 = a0
38 - 44 = a0

The starting term is -6

The solution is: The starting term is -6

What is Arithmetic progression?

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

Standard formula for arithmetic sequence:

an = a0 + d(n-1)

if we use the two terms given, setting a12 as starting term and a45 as the end term an.

170 = 38 + 33d

170 - 38 = 33d

132 = 33d

132/33 = d

This is the common difference, use it to find the first term.

38 = a0 + (132/33)(12-1)

38 = a0 + (132/33)(11)

38 = a0 + 132/3

38 - 132/3 = a0

38 - 44 = a0

-6 = a0

The dance committee has a budget of $125 to decorate the gym for the spring dance. They have already spent $65. Some members want to buy helium balloons that cost $0.80 each. Write and solve an inequality to show the number of balloons that the dance committee could buy

Answers

First, we subtract the price already spent:
125 - 65 = 60
Now to find the amount of balloons:
0.8n = 60
Divide:
n = 75
The dance committee can buy 75 balloons

The dance committee could buy up to 75 helium balloons with their remaining budget of $60, after already spending $65 from their total budget of $125.

To determine the number of helium balloons that the dance committee could buy with their remaining budget, we first need to calculate how much money they have left after already spending $65. Since their total budget is $125, the remaining budget is calculated as $125 - $65 = $60.

Let's let b represent the number of balloons they can buy. The cost per balloon is $0.80, so the inequality representing the situation is 0.80b \<= 60. To solve for b, we divide both sides of the inequality by 0.80, which gives us b \<= 60 / 0.80, or b \<= 75.

Therefore, the dance committee could buy up to 75 helium balloons with their remaining budget, staying within their financial limitations.

describe the steps you would use to factor 2x ^ 3 + 5x ^ 2 - 8x - 20 completely then State the factored form. this isn't multiple choice btw

Answers

Answer:

2·x^3 + 5·x^2 - 8·x - 20 = 0

You see that the term will be 0 for x = 2

(2·x^3 + 5·x^2 - 8·x - 20) / (x - 2) = 2·x^2 + 9·x + 10 = 0

You can use the abc-formula to solve the quadratic equation.

x = -2.5 ∨ x = -2

So the factored form will be

2·x^3 + 5·x^2 - 8·x - 20 = 2·(x - 2)·(x + 2)·(x + 2.5)

Answer:

2·x^3 + 5·x^2 - 8·x - 20 = 0

You see that the term will be 0 for x = 2

(2·x^3 + 5·x^2 - 8·x - 20) / (x - 2) = 2·x^2 + 9·x + 10 = 0

You can use the abc-formula to solve the quadratic equation.

x = -2.5 ∨ x = -2

So the factored form will be

2·x^3 + 5·x^2 - 8·x - 20 = 2·(x - 2)·(x + 2)·(x + 2.5)

If the total income generated from gasoline for AER was $408 million how much would be the cost for a barrel of gasoline, gasoline 34% kerosene 14% 60 million barrels total production crude oil

Answers

The problem statement appears to be trying to tell you that 60 million barrels of crude were processed, resulting in 34% of that volume being turned into gasoline, which was then sold for a total of $408 million. You are asked for the revenue associated with 1 barrel of gasoline.

($408·10^6)/(60·10^6 bbl × 0.34) = $408/(20.4 bbl) = $20/bbl

The income from one barrel of gasoline is $20.00.

The correct answer is: $20

Explanation:

As we are interested in finding the cost for a barrel of gasoline, we need to read the percentage of gasoline from the pie-chart first—which is 34%.

Now number of barrels containing gasoline = 34% of 60 million barrels = [tex] \frac{34}{100} * 60 = 20.4 [/tex] million barrels

For all the barrels, the total income is $408 million; therefore, in order to find the per-barrel cost, we need to divide $408 by 20.4:

[tex] \frac{408}{20.4} = \$20 [/tex]

Hence the correct answer is $20.

the sum of two numbers is 7 five times the larger number plus four times the the smaller number is 47.

Answers

Let x and y represent the larger and smaller numbers, respectively. The problem conditions give rise to two equations:
x + y = 7
5x +4y = 47

You can use the first equation to write an expression for y, then substitute that into the second equation.
y = 7 - x
5x +4(7 -x) = 47 . . . . substitute for y
x + 28 = 47 . . . . . . .. simplify
x = 19 . . . . . . . . . . . . subtract 28

Using our expression for y, we have
y = 7 -19 = -12

The larger number is 19.
The smaller number is -12.

Final answer:

The question is about solving simultaneous equations. Two equations can be set up from the statements provided: x + y = 7 (sum of two numbers is 7) and 5x + 4y = 47 (five times the larger number plus four times the smaller number equals 47). After setting up these equations, solve for x and y.

Explanation:

The subject you are asking about falls under the area of Mathematics, specifically simultaneous equations. To solve this question, we need to set up two equations based on the problem's statement and then solve these two equations together.

Given the problem that the sum of two numbers is 7 and five times the larger number plus four times the smaller number is 47, we can set it up as follows:

Let the larger number be x and the smaller number be y.The first statement gives us the equation: x + y = 7The second statement gives us the equation: 5x + 4y = 47

Subtracting the first equation from the second gives 4x + 3y = 40 so y = (40 - 4x)/3. Substituting y into the first equation gives x = 7 - (40 - 4x)/3. Solve for x to find the larger number, then substitute x into the equation y = 7 - x to find the smaller number.

Suppose a population proportion is .40, and 80% of the time when you draw a random sample from this population you get a sample proportion of .35 or more. how large a sample were you taking?

Answers

Final answer:

To determine the sample size needed, use the formula for sample proportion: n = (z * sqrt(p * q)) / E. Plugging in the given values, the minimum sample size required is 178.

Explanation:

To determine the sample size needed, we can use the formula for sample proportion:

n = (z * sqrt(p * q)) / E

Where:

n is the sample size

z is the z-value corresponding to the desired confidence level (in this case, 80%)

p is the population proportion (0.4)

q is 1 - p

E is the maximum allowable error (0.05)

Plugging in the values, we have:

n = (z * sqrt(p * q)) / E = (0.84 * sqrt(0.4 * (1 - 0.4))) / 0.05 ≈ 177.6

Since we cannot have a fractional number of individuals, we round up to the next whole number. Therefore, we would need a minimum sample size of 178 to be 80% confident that the population proportion is estimated to within 0.05.
