Set up an algebraic equation and then solve. An integer is 14 less than 4 times another. If the product of the two integers is 30 , then find the integers. The two integers are and I don't know 2 attemp
The two integers are 5 and 6.
Set up with algebraic equationTo solve this problem, we need to set up an algebraic equation based on the information given.
Let's call the first integer x and the second integer y. According to the problem, an integer (x) is 14 less than 4 times another (y).
This can be written as: x = 4y - 14
We are also told that the product of the two integers is 30. This can be written as:
xy = 30
Now we can substitute the first equation into the second equation to solve for one of the variables.
Let's solve for y:
(4y - 14)y = 30
4y^2 - 14y = 30
4y^2 - 14y - 30 = 0
Using the quadratic formula, we can solve for y:
y = (-(-14) ± √((-14)^2 - 4(4)(-30)))/(2(4))
y = (14 ± √(196 + 480))/8
y = (14 ± √676)/8
y = (14 ± 26)/8
y = 5 or y = -1.5
Now we can plug these values of y back into the first equation to find the corresponding values of x:
x = 4(5) - 14 = 6
x = 4(-1.5) - 14 = -20
So the two integers are either 5 and 6, or -1.5 and -20. However, since the problem asks for integers, we can eliminate the second solution.
Therefore, the two integers are 5 and 6.

(a) if tan∅ = 8/15, find the value of
sin∅ + cos∅(1- cos∅) (b)The angle of elevation of the top of a radio mask from a point due east of it and 96m away from its base is 30degrees. From another point, due west of the mask, the angle of elevation of the top is 60degrees. Calculate the distance of the second point from the base of the mast.
Answer:
Below in bold.
Step-by-step explanation:
The right triangle of which ∅ is a part has
Hypotenuse = sqrt(8^2 + 15^2)
= sqrt289
= 17,
So, sin ∅ = 8/17 and cos ∅ = 15/17
and
sin∅ + cos∅(1- cos∅)
= 8/17 + 15/17(1 - 15/17)
= 8/17 + 15/17 - 225/289
= 166/289.
(b) tan 30 = h/96 where h is height of the mast
h = 96 tan 30.
= 55.4256
tan 60 = 55.4256/d where d is the required distance
d = 55.4256/ tAN60
= 32 M

The profits exist the same (slope) but the y-intercept is more increased than the actual diagram.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
The slope-intercept form of a linear equation is where one side includes only "y"
2x+ 3y= 1470
y= -2/3 x + 490
Hence, the y-intercept exists at 490 and the slope is -2/3x.
As, 2x + 3y = 1593
3y = -2x +1593
y = -2/3x +531

Alex has a pile of two pence coins. She swapped exactly half of them for the same number of 10p coins. Now she has £4.20. How much money did Alex have initially?"
Alex initially had 60 two pence coins.
What is Algebra?Algebra is a branch of mathematics that deals with symbols and the rules for manipulating these symbols. It is used to solve problems and represent mathematical relationships and formulas. In algebra, letters and other symbols are used to represent numbers and quantities, allowing us to express mathematical relationships and patterns in a more general and abstract way.
What is Simplification?In mathematics, simplification refers to the process of reducing an expression or equation to a simpler form. This is typically done by applying mathematical operations or rules to the expression or equation to eliminate unnecessary terms, factors, or operations.
For example, if we have the expression (x^2 + 4x + 4)/(x + 2), we can simplify it by factoring the numerator and canceling out the common factor with the denominator. This gives us (x + 2), which is a simplified form of the original expression.
In the given question,
Let's start by using some algebra to solve the problem.
Let's say that Alex initially had x two pence coins. After swapping half of them for 10p coins, she would have x/2 ten pence coins. We can use this information to set up an equation relating the value of her coins to the total amount of money she ended up with:
0.02x + 0.10(x/2) = 4.20
Simplifying this equation, we get:
0.02x + 0.05x = 4.20
0.07x = 4.20
x = 60
So Alex initially had 60 two pence coins. Checking our answer, we can see that she swapped half of them for 30 ten pence coins. The value of her 60 two pence coins is 0.02 x 60 = £1.20, and the value of her 30 ten pence coins is 0.10 x 30 = £3.00. Together, these add up to £4.20, as required.

A sandwich shop makes home deliveries. The average amount of time from when an order is placed until when it is delivered can be modeled by the equation y = 2.5x + 5, where x is the number of miles between the shop and the delivery location and y is the time in minutes. Which of these statements are correct according to the model? Select two that apply.
The correct statements according to the model are: if the delivery location is 0 miles away, the order will take 5 minutes to be delivered, and if the delivery location is 10 miles away, the order will take 30 minutes to be delivered.
What is statements ?
A statement is a sentence that expresses a complete thought and can be either true or false. In mathematics, statements are often used to make claims or propositions that can be proven or disproven using logical reasoning and evidence.
The equation y = 2.5x + 5 models the average amount of time from when an order is placed until when it is delivered for a sandwich shop that makes home deliveries, where x is the number of miles between the shop and the delivery location, and y is the time in minutes.
To answer the question, we need to look at the statements and see which ones are correct according to the model:
If the delivery location is 0 miles away, the order will take 5 minutes to be delivered.
This statement is true because if x=0, then y=2.5(0)+5=5, which means the order will take 5 minutes to be delivered.
If the delivery location is 10 miles away, the order will take 30 minutes to be delivered.
This statement is true because if x=10, then y=2.5(10)+5=30, which means the order will take 30 minutes to be delivered.
If the delivery location is 1 mile away, the order will take 2.5 minutes to be delivered.
This statement is false because if x=1, then y=2.5(1)+5=7.5, which means the order will take 7.5 minutes to be delivered, not 2.5 minutes.
If the delivery location is 5 miles away, the order will take 20 minutes to be delivered.
This statement is false because if x=5, then y=2.5(5)+5=17.5, which means the order will take 17.5 minutes to be delivered, not 20 minutes.
Therefore, the correct statements according to the model are: if the delivery location is 0 miles away, the order will take 5 minutes to be delivered, and if the delivery location is 10 miles away, the order will take 30 minutes to be delivered.

A local county has an unemployment rate of 6.5%. A random sample of 20 employable people are picked at random from the county and are asked if they are employed. The distribution is a binomial. Round answers to 4 decimal places. a) Find the probability that exactly 3 in the sample are unemployed. b) Find the probability that there are fewer than 3 in the sample are unemployed. c) Find the probability that there are more than 2 in the sample are unemployed. d) Find the probability that there are at most 3 in the sample are unemployed.
The distribution is binomial.
a) The probability that exactly 3 in the sample are unemployed is 0.0311, b) The probability that there are fewer than 3 in the sample are unemployed is 0.5354, c) The probability that there are more than 2 in the sample are unemployed is 0.4646, d) The probability that there are at most 3 in the sample are unemployed is 0.5665.
The binomial distribution formula is P(x) = (nCx)(p^x)(q^(n-x)), where n is the number of trials, x is the number of successes, p is the probability of success, and q is the probability of failure.
a) To find the probability that exactly 3 in the sample are unemployed, we plug in the values: n = 20, x = 3, p = 0.065, and q = 0.935.
P(3) = (20C3)(0.065^3)(0.935^17) = 1140(0.000274625)(0.099961375) = 0.0311
b) To find the probability that there are fewer than 3 in the sample are unemployed, we need to find the probability that 0, 1, or 2 are unemployed and add them together.
P(0) = (20C0)(0.065^0)(0.935^20) = 1(1)(0.1645) = 0.1645
P(1) = (20C1)(0.065^1)(0.935^19) = 20(0.065)(0.1725) = 0.2249
P(2) = (20C2)(0.065^2)(0.935^18) = 190(0.004225)(0.1812) = 0.1460
P(<3) = P(0) + P(1) + P(2) = 0.1645 + 0.2249 + 0.1460 = 0.5354
c) To find the probability that there are more than 2 in the sample are unemployed, we can subtract the probability that there are fewer than 3 from 1.
P(>2) = 1 - P(<3) = 1 - 0.5354 = 0.4646
d) To find the probability that there are at most 3 in the sample are unemployed, we can add the probabilities that there are 0, 1, 2, or 3 unemployed.
P(≤3) = P(0) + P(1) + P(2) + P(3) = 0.1645 + 0.2249 + 0.1460 + 0.0311 = 0.5665
Therefore, the answers are:
a) 0.0311

You need a home loan of $65,000 after your down payment. How much will your monthly house payment be in the bank charges 6.25% APR for a loan of 15 years?( simplify your answer completely. Round your answer to the nearest cent)
Your monthly house payment given that the bank charges 6.25% APR for a loan of 15 years will be $51.95.
To find the monthly house payment for a loan of $65,000 with a 6.25% APR for 15 years, we can use the formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]
Where:
M = monthly payment
P = principal amount
i = monthly interest rate
n = number of monthly payments
First, we need to find the monthly interest rate and the number of monthly payments:
i = 6.25% / 12 = 0.00625
n = 15 years(12 months/year) = 180 months
Now we can plug these values into the formula:
M = 65,000 [ 0.00625(1 + 0.00625)^180 ] / [ (1 + 0.00625)^180 - 1]
M = 65,000 [ 0.00625(1.00625)^180 ] / [ (1.00625)^180 - 1]
M = 65,000 [ 0.024636 ] / [ 0.171184 ]
M = 65,000 [ 0.143875 ]
M = 9,351.88
So, the monthly house payment will be $9,351.88 / 180 = $51.95.

Heather runs 3 miles in 28 minutes. At the same rate, how many miles would she run in 42 minutes?
Heather runs 3 miles in 28 minutes, so at the same rate, she would run 4.494 miles in 42 minutes.
To find out how many miles Heather would run in 42 minutes at the same rate, we use the concept of unit rate. Unit rate is a comparison of two different quantities when they are combined together. In this case, we need to find the unit rate of Heather's running speed in miles per minute.
Step 1: Find the unit rate of Heather's running speed in miles per minute.
To do this, we divide the distance she ran by the time she took to run it:
3 miles ÷ 28 minutes = 0.107 miles per minute
Step 2: Use the unit rate to find out how many miles Heather would run in 42 minutes.
To do this, we multiply the unit rate by the time she runs:
0.107 miles per minute × 42 minutes = 4.494 miles

First, we need to find Kai's rate (or speed). We can do this by rearranging the formula to solve for r:
r = d/t
Plug in the values we know:
r = 376 miles / 8 hours
Simplify:
r = 47 miles per hour
Now that we know Kai's rate, we can plug it back into the distance formula to find out how far he drives in 10 hours:
d = rt
d = (47 miles per hour) (10 hours)
Simplify:
d = 470 miles

8 The trinomial 4x^(2)-20x+25 is factorable. Which of these is the correct factorization? F (2x+5)(2x-5) G (2x-5)^(2) H (2x+5)^(2) J (x-5)(4x-5)
The trinomial 4x²-20x+25 is factorable. The correct factorization of the trinomial 4x²-20x+25 is H (2x+5)².
To factor a trinomial, we need to find two numbers that multiply to give the constant term (25) and add to give the coefficient of the middle term (-20). In this case, the two numbers are -5 and -5. We can then write the trinomial as (4x²-10x-10x+25), and factor by grouping:
4x²-10x-10x+25 = (4x^(2)-10x) + (-10x+25) = 2x(2x-5) - 5(2x-5) = (2x-5)(2x-5) = (2x+5)²
Therefore, the correct factorization of the trinomial is H (2x+5)²

Does anyone knows this Central Angle
The value of x is
x=-5
What is The value of x?
Generally, An angle is a figure formed by two rays (or line segments) that share a common endpoint. Angles are usually measured in degrees, with a full angle measuring 360 degrees.
Considering that the angle on a point is 630 , we have that the missing angle is
y=360-(148+92)
y=120
Therefore
y=x+125
Hence
x=y-125
x=120-125

Are these triangles CBA-FGH similar
The two triangles cannot be similar, because they have one pair of corresponding angles that are not equal.
What is triangle ?
A triangle is a geometric shape consisting of three straight sides and three angles. The sum of the angles in a triangle is always 180 degrees. The point where two sides of a triangle meet is called a vertex. The side opposite to a vertex is called the opposite side, and the angle opposite to a side is called the opposite angle.
To determine if two triangles are similar, we need to check if their corresponding angles are equal and their corresponding sides are proportional.
Let's start with the angles:
In triangle CBA, we can use the Law of Cosines to find the measure of angle C:
[tex]cos(C) = (a^2 + b^2 - c^2) / (2ab)[/tex]
where a, b, and c are the side lengths opposite to angles A, B, and C, respectively.
[tex]cos(C) = (72^2 + 48^2 - 84^2) / (2 x 72 x 48)[/tex]
cos(C) = -0.25
Since cos(C) is negative, we know that angle C is obtuse.
Now, let's consider triangle FGH. By the Law of Cosines, we can find the measure of angle H:
[tex]cos(H) = (f^2 + g^2 - h^2) / (2fg)[/tex]
[tex]cos(H) = (8^2 + 12^2 - 14^2) / (2 x 8 x 12)[/tex]
cos(H) = 0.25
Since cos(H) is positive, we know that angle H is acute.
Therefore, the two triangles cannot be similar, because they have one pair of corresponding angles that are not equal.
