Problem part 1: Mia has $20 to spend. Which inequality can be used to represent this situation?
Problem part 2: If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy.
The inequality that can be used to represent this situation is 2x + 1.50y ≤ 20.
The maximum number of apples she can buy is 7 apples.
How to represent inequality?Mia went into a grocery store and where they sell apples for $2 each and mangos $1.50 each.

Answer:
Step-by-step explanation:
okay so what I would do is multiply the denominator of 3 from 2/3 by 4 to get 12. So what you do to the bottom you have to do to the top so that fraction 2/3 will turn to 8/12.
Then I would multiply the denominator of 4 from 1/4 by 3 to get also get 12. And again what you do to the bottom you have to do to the top. So that fraction will be 3/12.
Ten you add them 8/12 + 3/12 = 11/12

If ABCD is a parallelogram, what is the measure of
D
A/9x + 5

C
B
If ABCD is a parallelogram, then the measure of D is 68
From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.
25x + 5 = 180
25x = 180 - 5
25x = 175
x = 7
now let's substitute in the angle < DAB( 16x): 16 × 7= 112To get < ADC lets use the property of parallelogram which says that adjacent angles are supplementary. which means<ADC+ <DAB= 180
<ADC+ 112 = 180
< ADC= 180 - 112
< ADC = 68
Therefore, the measure of D is 68

there are 498 identical plastic chips numbered 1 through 498 in a box. what is the probability of reaching into the box and randomly drawing a chip number that is greater than 315? express your answer as a simplified fraction or a decimal rounded to four decimal places.
The probability of reaching into the box and randomly drawing a chip number that is greater than 3150 is 0.3675
In this question we have been given there are 498 identical plastic chips numbered 1 through 498 in a box.
We need to find the probability of reaching into the box and randomly drawing a chip number that is greater than 315
Total number of chips = 498
so, n(S) = 498
Let event A: drawing a chip number that is greater than 315
The number of chips greater than 315:
498 - 315 = 183
So, n(A) = 183
The probability of reaching into the box and randomly drawing a chip number that is greater than 315 using the formula of probability,
p(A) = n(A)/n(S)
p(A) = 183/498
p(A) = 0.3675
Therefore, the required probability is 0.3675

Which equation is enough information to prove that lines m and n are parallel lines cut by transversal p? select three options. a = c a = d c = d b c = 180° b d = 180°
One of the alternatives isc=d because when a line meets two parallel lines, matching angles are created and the identical corners are congruent.
What are parallel lines?Coplanar, straight lines that don't intersect anywhere are considered parallel lines in geometry. Planes in the same three-dimensional space that never cross each other are said to be parallel. Curves that are parallel to one another and maintain a set minimum distance do not touch or intersect. Lines in a plane that consistently have the same separation are said to be parallel. Nothing can cross a parallel line. Lines that cross at a straight angle of 90 degrees are called perpendicular lines.
A = d is also a solution due to vertical angles. Finally, b+d=180 since b+c=180 and c=d, and b+d=180 as a result. The solution is therefore B,C,E, where a=d, c=d, and b+d=180.

To secure a 500-meter radio tower against high winds,
guy wires are attached to the top of the tower. Each wire
forms a 15° angle with the top of the tower. Find the length
of the wire from the tower to its anchor in the ground.
Answer: To find the length of the wire from the tower to its anchor in the ground, you can use the formula for the length of a side in a 30-60-90 triangle. Since the angle between the wire and the tower is 15°, the angle between the wire and the ground is 75° (90° - 15°). This means that the wire and the tower form a 30-60-90 triangle.
In a 30-60-90 triangle, the side opposite the 30° angle is half as long as the hypotenuse, and the side opposite the 60° angle is half as long as the side opposite the 90° angle. Since the wire is the hypotenuse of the triangle, and the wire is opposite the 60° angle, the length of the wire from the tower to its anchor in the ground is half as long as the hypotenuse.
Therefore, the length of the wire from the tower to its anchor in the ground is 500/2 = 250 meters.

The proof for the Base Angles Theorem is explained below:
What is meant by Base Angles Theorem?A triangle's opposite angles are congruent if its two sides are congruent. We shall build the angle bisector through the vertex angle of an isosceles triangle in order to demonstrate the Base Angles Theorem. We created two congruent triangles by building the angle bisector, and then we utilized CPCTC to prove that the base angles are congruent. Base angles: The angles that include the base of an isosceles triangle are known as the "base angles."
Any triangle with at least two congruent sides is said to be isosceles. Legs are the isosceles triangle's congruent sides. The base is the other side. Base angles are the angles formed between the base and the legs.

4 Describe at least two different transformations or sequences of transformations that
transform square A to square B.
The orientation of ABCD is clockwise, as is the orientation of A'B'C'D'. This means the transformation involves a even number of reflections (may be 0).
Does the order of transformations matter in functions?
Order is not important. According to algebra, y=12f (x3). Our four transformations are (1), (3), (2), and (4); all four are in the x direction. When we combine a stretch and a translation in the same direction, the sequence counts.
The orientation of AB is North, and the orientation of A'B' is West, so a rotation of 90° CCW (or equivalent) is involved. We can find the point of intersection of the perpendicular bisectors of AA' and BB' (at (-1, -1)) to determine a suitable center of rotation.
ABCD can be transformed to A'B'C'D' by ...
rotation 90° CCW about the point (-1, -1)
Rotation by 90° can also be accomplished by reflection across a diagonal line. Since we want the orientation to remain unchanged, we need another reflection to put the figure into its final position. A suitable alternate sequence for mapping ABCD to A'B'C'D' is ...
reflection across the line y=x

A cryotherapy chamber uses extreme cold to reduce muscle soreness. A chamber is currently 0°F. The temperature in the chamber is dropping 2.5°F every second. Identify an inequality that represents the numbers of seconds $s$ that can pass for the temperature to drop below -20 °F
Answer: The answer is $s$ > 7, which represents the number of seconds that can pass for the temperature in the cryotherapy chamber to drop below -20°F.
Step-by-step explanation: The temperature in the chamber will drop below -20°F when it reaches -20°F + 2.5°F = -17.5°F.
The temperature in the chamber is currently 0°F, so we can represent this situation with the inequality 0 - (2.5 * $s$) < -17.5, where $s$ is the number of seconds that can pass.
We can simplify this inequality by multiplying both sides by -1 to get the following: 2.5 * $s$ > 17.5.
Dividing both sides by 2.5, we get the final inequality: $s$ > 7.
Therefore, the number of seconds $s$ that can pass for the temperature in the cryotherapy chamber to drop below -20°F is greater than 7 seconds.

Two cities are 145 miles apart. A truck travels this distance in 2.5 hours. A car is 1.5 times as fast as the truck. How long does it take the car and the truck to meet if they leave at the same time and travel toward each other
The time it will take the car and truck to meet is 5hours
What is velocity?Velocity is the rate of change of displacement with time. It is a vector quantity and it is measured in meter per seconds but it can also be measured in other units like kilometers per hour and miles per hour.
Velocity = displacement/time
the velocity of the truck is 145/2.5 = 58miles per hour
the car is 1.5 times faster than the truck
this means the velocity of the car is 58× 1.5= 87miles per hour
displacement = velocity×time
total displacement = 145miles
displacement of car = 87t
displacement of truck = 58t
using addition of vectors
145=87t-58t
145= 29t
t = 145/29

Step-by-step explanation:
Answer:
Length of garden is 50 m.
Step-by-step explanation:
Fence required for 1 time,
→ 400 ÷ 2
→ 200 m
Perimeter of square formula is,
→ P = 4 × L
Now length of the garden will be,
→ P = 4 × L
→ 200 = 4L
→ 4L = 200
→ L = 200/4
→ [ L = 50 m ]
Hence, length of garden is 50 m.
