The total number of peaches is given by the equation A = 25 peaches
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of peaches be represented as A
Now , the equation will be
The percentage of peaches that equals 7 peaches = 28 %
Substituting the values in the equation , we get
28 % of A = 7 be equation (1)
On simplifying the equation , we get
( 28 / 100 ) x A = 7
Multiply by 100 on both sides of the equation , we get
28A = 700
Divide by 28 on both sides of the equation , we get
A = 700/28
A = 25 peaches

If P = (5, 4), Find:
r90° (P)
Answer:
r90° (P) = (4, -5).
Step-by-step explanation:
The point P is (5, 4). To find the image of P after rotating it 90° counterclockwise, we use the transformation matrix for a 90° counterclockwise rotation:
[[0, -1], [1, 0]]
The coordinates of the image of P after rotating 90° counterclockwise are given by:
[[0, -1], [1, 0]] * [5, 4] = [4, -5]
So, r90° (P) = (4, -5).

m∠2 = (y + 10)° and m∠4 = (3y – 24)°
What is m∠2?
The measure of angle 2 from the given figure is 27°.
What is vertical angle theorem?Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.
Given that, m∠2 = (y+10)° and m∠4 = (3y-24)°.
Here, m∠2=m∠4 (∵ Opposite vertical angles are equal)
(y+10)°=(3y-24)°
3y-y=10+24
2y=34
y=17
So, m∠2 = (y+10)°=27°
Therefore, the measure of angle 2 from the given figure is 27°.

Given each pre-image and image, determine the scale factor.
*Note: The pre-image is notated by the shaded gray area. Your answer should be given as a whole number or fraction.
The scale factor of the dilation transformation of the pre-image triangle ΔDEF to the image ΔD'E'F', with the origin as the center of dilation is 3.
What is a dilation transformation?A dilation transformation is one in which the lengths of the sides of the pre-image are scaled up by a common factor to get the lengths of the sides of the image.
The coordinates of the vertices of the triangle ΔDEF are;
D(1, 5), E(1, 2), F(3, 2)
The length of the sides of triangle ΔDEF, making use of the difference between the non equal coordinate points, are;
DE = 5 - 2 = 3
EF = 3 - 1 = 2
The length of the side DF can be found using the formula for the distance between two points on the coordinate plane (a form of the Pythagorean Theorem), which is presented as follows;
DF = √((3 - 1)² + (2 - 5)²) = √(2² + (-3)²) = √(13)
The coordinates of the vertices of triangle ΔD'E'F' are; D'(3, 15), E'(3, 6), F'(9, 6)
Therefore; D'E' = 15 - 6 = 9
E'F' = 9 - 3 = 6
D'F' = √((9 - 3)² + (6 - 15)²) = √(6² + (-9)²) = √(9 × 13) = 3·√(13)
The scale factor, s.f. = The ratio of the corresponding sides of the triangles which is found as follows;
D'E'/DE = 9/3 = 3
E'F'/EF = 6/2 = 3
D'F'/DF = 3·√(13)/√(13) = 3
s.f. = D'E'/DE = E'F'/EF = D'F'/DF = 3

Two angles of a quadrilateral measure 74° and 231°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?
Answer:
22° and 33°
Step-by-step explanation:
the sum of the interior angles of a quadrilateral = 360°
the ratio of the other 2 angles = 2 : 3 = 2x : 5x ( x is a multiplier )
sum the 4 angles and equate to 360
2x + 3x + 74 + 231 = 360
5x + 305 = 360 ( subtract 305 from both sides )
5x = 55 ( divide both sides by 5 )
x = 11
then
2x = 2 × 11 = 22°
3x = 3 × 11 = 33°
the other 2 angles have a measure of 22° and 33°
How do you solve a 30 60 90 problem?
To solve a 30-60-90 triangle problem, you can use the ratios of the sides of a 30-60-90 triangle. The ratios are:
The hypotenuse is opposite the 60 degree angle, and it is always twice the length of the shorter leg.
The longer leg is opposite the 90 degree angle, and it is always √3 times longer than the shorter leg.
The shorter leg is opposite the 30 degree angle, and it is always equal to x where x is the value of the shorter leg.
So, you can use these ratios to find the missing side length(s) of a 30-60-90 triangle, given the length(s) of the other side(s). For example, if you know the length of the hypotenuse, you can find the lengths of the other two sides by dividing the hypotenuse by 2 and √3, respectively.

if the racetrack publishes that the odds in favor of a horse winning a race are 2 to 4, what is probability that the horse will not win the race?
The probability that the horse will not win the race is 0.5. The result is obtained by subtracting the probability of winning from 1.
How to calculate probability?Probability of an event can be expressed as
P(A) = n(A) / n(S)
Where
P(A) is the probability of an event An(A) is the number of favorable outcomesn(S) is the total number of events in the sample spaceWhile, the probability for the opposite event is
P(not A) = 1 - P(A)
If the probability that a horse will win the race is 2/4, find the probability that the horse won't win the race!
The probability that the horse will win the race is
P = 2/4 = 0.5

The angle be 5x - 12 and 3x - 8 then the value of x = 25.
What is meant by measure of angle?The angle created by the two rays or arms at a shared vertex is known as the angle measure in geometry.
Two straight lines or rays intersect at a same terminus to make an angle. The vertex of an angle is the point at which all points meet. Angle is derived from the Latin word angulus, which means "corner."
A protractor is a precision tool for measuring angles. Angles are measured in degrees, therefore the term "degree measure." Because one full revolution is equivalent to 360 degrees, it is divided into 360 segments.
Let the two angle be 5x - 12 and 3x - 8
5x + 3x - 12 - 8 = 180
Add similar elements: 5x + 3x = 8x
8x - 12 - 8 = 180
Subtract the numbers: -12 - 8 = -20
8x - 20 = 180
Move 20 to the right side
8x = 200
Divide both sides by 8
= 8x / 8 = 200 / 8
x = 25

What is the sum of the exterior angles of a polygon with 15 sides?
So, the sum of the exterior angles of a polygon with 15 sides is 2340 degrees.
The sum of the exterior angles of a polygon can be found using the formula: (n-2) * 180 degrees, where n is the number of sides of the polygon.
In the case of a polygon with 15 sides, the number of sides (n) is 15. Therefore, the sum of the exterior angles can be found by plugging in 15 for n and solving the equation:
(15-2) * 180 = (13) * 180 = 2340 degrees
Therefore, the sum of the exterior angles of a polygon with 15 sides is 2340 degrees.
It's worth noting that the sum of all exterior angles of a polygon is always 360 degrees less than the sum of the interior angles of a polygon.
The sum of the interior angles of a polygon with n sides is (n-2)*180.
So for a 15 sided polygon the sum of the interior angles is (15-2)*180 = 2340 degrees.
