The larger of the two integers is 18 and the smaller integer is 17.
Integers are collection of whole numbers and negative numbers. Integers are not fractional numbers or decimal. Some examples of integers are -5,-25,0,13,9 .
Let us consider the smaller integer be x.
As the integers are consecutive, the larger integer is (x+1).
Now according to the given condition:
Twice the large integer=2(x+1)
15 less than the 3 times the smaller integer=3x-15
Now the value of these two expressions is equal.
Therefore: [tex]2(x+1)=3x+-15[/tex]
Solving the above equation to find the value of x:
[tex]or,2(x+1)=3x-15\\or,2x+2=3x-15\\or,2x-3x=-15-2\\or,-x=-17\\or,x=17[/tex]
Therefore the smaller integer is 17.
Larger integer(x+1) : 17+1=18
Therefore the integers are 17 and 18.

A member of the junior varsity swim team will be elected as President. Each member is equally likely to be elected. The probability that a sophomore is elected is $3/2$ times the probability that a freshman is elected. Everyone on the junior varsity swim team is either a freshman or sophomore. What fraction of the swim team are sophomores?
Using the probability concept, it is found that 60% of the swim team are sophomores.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The sum of the probabilities of all outcomes of an event is of 1, hence:
P(freshman) + P(sophomore) = 1.
The probability that a sophomore is elected is $3/2$ times the probability that a freshman is elected, hence:
x + 3/2x = 1.
5/2x = 1

Please help me with this question I'm so confused
Answer:
x is equal to 15.
Step-by-step explanation:
In this problem, it is said that ΔABC ~ ΔXYZ. This means that the shapes are the same, however they are not the same size. Here the problem is asking for the value of x when the triangle is scaled up.
Look on the triangles for where there are values on both ABC and XYZ. Notice that the hypotenuse for both triangles have a value.
The hypotenuse of triangle XYZ is 10, while the hypotenuse of triangle ABC is 25. Dividing both of those results by 10 results in a 1:2.5 ratio, meaning that the values of triangle ABC are 2.5 times larger than the values of triangle XYZ.
Knowing this, take the value of XZ on triangle XYZ, and multiply it by 2.5 to get the value of AC on triangle ABC, or x.
6 * 2.5 = 15
The value of x is 15.
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar that means that the sides are proportional. There are a couple of ways to find x. One way is to find the scale factor. We can use the two corresponding sides that we know. 25 and 10 are corresponding sides. They are both the hypotenuse of their triangles or you can say that they are both the side across from the 90 degree angle.
There is some number that I can multiple 10 by to get 25. This is my scale factor. This is how I can find it.
Let s = the scale factor.
10s = 25 Divide both sides of the equation by 10
s = 2.5 This means that each side of the larger triangle is 2.5 times longer than each side of the original triangle.
To find x. Find is corresponding side on the right and take that length and multiple it by 2.5
6 x 2.5 = 15
Another way is to set up a proportion.
[tex]\frac{10}{6}[/tex] = [tex]\frac{25}{x}[/tex] I could cross multiply and solve for x
10x = (6)(25)
10x = 150 Divide both sides by 10
x = 15

Approximately how much fencing is needed to enclose a circular pond with a diameter of 12. 5 feet?.
Approximately 39.26 feet is needed to enclose a circular pond with a diameter of 12. 5 feet.
What is the circumference of a circle?The circumference (from Latin circumference, meaning "carrying around") is the perimeter of a circle or ellipse in geometry. That is, the circumference would be the circle's arc length if it were finally opened and straightened out to a line segment. In general, the perimeter is the length of the curve around any closed figure. The circumference can also refer to the circle itself, i.e. the locus corresponding to a disk's edge. A sphere's circumference is the circumference, or length, of any of its great circles.To fin the circumference:
Formula: C = 2πrRadius = Diameter/2 = 12.5/2 = 6.25So,
C = 2πr= 2 · π · 6.25≈ 39.26991Therefore, approximately 39.26 feet is needed to enclose a circular pond with a diameter of 12. 5 feet.

As treasurer of her school's 4H club, Carol wants to buy gifts for all
11 members. She can buy t-shirts for $5 and sweatshirts for $12.
The club has $118 to spend and Carol wants to spend all of the
money. How many of each type of gift should she buy?
Using algebraic expressions and equations, Carol should buy 2 t-shirts and 9 sweatshirts.
We can set up an algebraic expressions and equations to determine how many of each type of gift should Carol buy.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
1. Write an equation for the total number of members.
x + y = 11 (equation 1)
where x is the number of members who will get t-shirt
y is the number of members who will get sweatshirt
2. If each t-shirt costs $5 and each sweatshirt costs $12, write an equation for the total amount spent buying the gift.
$5(x) + $12(y) = $118 (equation 2)
where x is the number of members who will get t-shirt
y is the number of members who will get sweatshirt
3. Rewrite equation 1 as an equation of y in terms of x.
x + y = 11 (equation 1)
y = 11 - x
4 . Plug in the expression for y in equation 2 and solve for x.
$5(x) + $12(y) = $118 (equation 2)
5x + 12(11 - x) = 118
5x + 132 - 12x = 118
-7x = -14
x = 2
5. Substitute the value of x in either equation 1 or 2 and solve for x.
x + y = 11 (equation 1)
2 + y = 11
y = 11 - 2
y = 9
Hence, Carol should buy 2 t-shirts and 9 sweatshirts.
Checking,
2 + 9 = 11
Each member will receive a gift.
2($5) + 9($12) =$118
Carol will be spending $118 for the gifts.

Find the velocity, acceleration, and speed of a particle with the given position function. r(t) = t i t2 j 2 k
The velocity of a particle = i + 2t j
The acceleration of a particle = 2 j
The speed of a particle = [tex]\sqrt{1 + 4t^{2} }[/tex]
Here,
The position function is, [tex]r (t ) = ti + t^{2} j +2k[/tex]
We have to find, the velocity, acceleration, and speed of a particle with the given position function.
What is Velocity of a particle with the given position function?
The instantaneous velocity v(t) of a particle is the derivative of the position with respect to time. That is, v(t)=dx/dt.
Now,
The position function is, [tex]r (t ) = ti + t^{2} j +2k[/tex]
The velocity of a particle = [tex]\frac{d r(t)}{dt}[/tex]
[tex]r (t ) = ti + t^{2} j +2k[/tex]
[tex]\frac{d r(t)}{dt} = i + 2t j[/tex]
The acceleration of a particle = [tex]\frac{d^{2} r(t)}{dt^{2} }[/tex]
[tex]r (t ) = ti + t^{2} j +2k[/tex]
[tex]\frac{d r(t)}{dt} = i + 2t j[/tex]
[tex]\frac{d^{2} r(t)}{dt^{2} }= 2j[/tex]
The speed of a particle = [tex]| \frac{d r(t)}{dt}| = |v(t)|[/tex]
[tex]\frac{d r(t)}{dt} = i + 2t j[/tex]
[tex]|v(t)|=\sqrt{1 + 4t^{2} }[/tex]
Hence, The velocity of a particle = [tex]i + 2t j[/tex]
The acceleration of a particle = [tex]2 j[/tex]
The speed of a particle = [tex]\sqrt{1 + 4t^{2} }[/tex]

a) The distance of the plane from the airport is approximately 781.025 miles.
b) The bearing of the airplane in standard position is approximately 320.194°.
How to calculate the distance and the bearing of the bearing from the airport
Let the location of the airport be the origin and the orthogonal axes are oriented to the east and north, respectively. Beside, let consider that the plane moves at constant speed. a) Thus, the distance of the plane can be found by using the Pythagorean Theorem:
d = √[[(240 mi / h) · (2.5 h)]² + (500 mi)²]
d ≈ 781.025 mi
