Step-by-step explanation:
Create a list of steps, in order, that will solve the following equation.
2
(
x
+
2
)
2
−
5
=
93
To solve 2(x + 2)^2 - 5 = 93, add 5 to both sides, divide by 2, take the square root of both sides, and finally subtract 2 to find x = 5 and x = -9.
To solve the equation 2(x + 2)^2 - 5 = 93, follow these steps:
First, add 5 to both sides of the equation to isolate the squared term: 2(x + 2)^2 = 98.
Divide both sides of the equation by 2 to get: (x + 2)^2 = 49.
Take the square root of both sides of the equation: x + 2 = 7. Remember that taking the square root yields two possible solutions.
Subtract 2 from both sides to solve for x: x = 5 and x = -9.
Therefore, the solutions to the equation are x = 5 and x = -9.
Order each set of integers from greatest to least
(8, 43, -25, 12, -14, 3)
(-8, 32, 55, -32, -19, -3)
(-100, -89, -124, -69, -52)
(6, 17, -20, -19, 26)
The ordered sets are: (43, 12, 8, 3, -14, -25), (55, 32, -3, -8, -19, -32), (-52, -69, -89, -100, -124), and (26, 17, 6, -19, -20).
To order each set of integers from greatest to least, we start by identifying the largest integer in each set and then follow with the next largest until we reach the smallest integer. Let's order the provided sets one by one:
For the set (8, 43, -25, 12, -14, 3), the order from greatest to least is: 43, 12, 8, 3, -14, -25.
The set (-8, 32, 55, -32, -19, -3) ordered from greatest to least is: 55, 32, -3, -8, -19, -32.
Ordering the set (-100, -89, -124, -69, -52) from greatest to least gives us: -52, -69, -89, -100, -124.
Finally, the set (6, 17, -20, -19, 26) ordered from greatest to least is: 26, 17, 6, -19, -20.
By comparing the positive and negative integers, we determine their placement in the sequence from greatest to smallest.
Solve for z -
-4.75 = z/2 (z/2 is a fraction)
z = ____
Answer:
z= -9.5
Step-by-step explanation:
To solve for z, we need to get z by itself.
-4.75=z/2
z is being divided by 2. To undo this, multiply both sides by 2, since multiplication is the opposite of division. This will cancel out the 2 on the right, and leave z by itself.
2*-4.75=z/2*2
-9.5=z
So, z= -9.5
Final answer:
To solve for z in the equation -4.75 = z/2, multiply both sides by 2, which yields z = -9.5
Explanation:
To solve for z in the equation -4.75 = z/2, we need to isolate z. We can do this by multiplying both sides of the equation by 2. Doing so gives us:
-4.75 × 2 = (z/2) × 2
-9.5 = z
So, z = -9.5
Which triangle can be solved using the law of sines?
The triangle C can be solved using the law of sines.
What is the law of sines?
'The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.'
According to the given problem,
We know,
Law of sines = [tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]
In triangle C,
Third angle = 180 - ( 70 + 30 )
= 180 - 100
= 80°
⇒ [tex]\frac{10}{sin30 }= \frac{b}{sin70} =\frac{c}{sin80}[/tex]
⇒ [tex]\frac{10}{sin30}= \frac{b}{sin70}[/tex]
⇒ 20 × 0.9396 = b
⇒ b = 18.8 m
⇒ [tex]\frac{10}{sin30}=\frac{c}{sin80}[/tex]
⇒ 20 × 0.9848 = c
⇒ c = 19.7 m
Hence, we can conclude that tringle C can be solved using the law of sines.

Which integer represents this situation?
A skydiver jumped out of a plane at an elevation of 1,600 feet.
0
1,600
-1,600
The Answer of the question is "B" or 1,600
Final answer:
The correct integer representing the skydiver's elevation is +1,600 feet. This positive value indicates that the skydiver is above the ground level when they jump from the plane.
Explanation:
To determine which integer represents a skydiver's elevation after jumping out of a plane at 1,600 feet, consider the direction of the elevation change relative to the ground. If we have our origin at the ground level and define upward as positive, then a skydiver jumping out of a plane is moving from a positive elevation down towards the ground. Therefore, their starting elevation is a positive value.
In this context, the appropriate integer to describe the skydiver's starting elevation of 1,600 feet is +1,600, and not 0 or -1,600. No elevation would be represented by 0, and a negative elevation value would imply that the skydiver is below the ground level, which is not the case at the start of the skydive.

If the sum is 6, a small cone will be ordered . If the sum is 7 or 9, a medium cone will be ordered If the sum is 8 a large cone will be ordered
Answer:
C) If the sum is 6, a small cone will be ordered . the sum is 7 or 8 , a medium cone will be ordered. If the sum is 9, a large cone will be ordered
Step-by-step explanation:
If the sum is a 6: (2+4) or (4+2)
P(6) = (2 is first picked)(4 is picked next) + (4 is first picked)(2 is picked next)
[tex] P(6)= (\frac{1}{4})(\frac{2}{3}) +(\frac{2}{4})(\frac{1}{3})[/tex]

If the sum is a 8: (4+4)
[tex] P(8)= (\frac{2}{4})(\frac{1}{3})=\frac{1}{6}[/tex]
If the sum is a 9: (4+5) or (5+4)
P(9) = (4 is first picked)(5 is picked next) + (5 is first picked)(4 is picked next)
[tex] P(9)= (\frac{2}{4})(\frac{1}{3}) +(\frac{1}{4})(\frac{2}{3})[/tex]
[tex] P(9) =\frac{1}{6} + \frac{1}{6} = \frac{1}{3} [/tex]
[tex] P(6) = \frac{1}{3} [/tex]
[tex] P(7) = \frac{1}{6} ;P(8) = \frac{1}{6} [/tex]
[tex]P(7) or P(8) = \frac{1}{6} + \frac{1}{6} = \frac{1}{3} [/tex]
[tex] P(9) = \frac{1}{3} [/tex]
Therefore, if the sum is 6, a small cone will be ordered . the sum is 7 or 8 , a medium cone will be ordered. If the sum is 9, a large cone will be ordered

y=25x+35
Describe what this graph would look like. Where would it start? How would the slope be counted out?
Answer:
The equation is in the form y=mx+b, where m=slope, b=y-intercept.
The y-intercept is 35: so the line goes through the y-axis at (0,35).
The slope is 25: so we need to count out the slope as rise over run, or 25 up and 1 to the right, starting from the y-intercept.

On a survey, 3 out of every 8 band members prefer listening to jazz music.
Based on the survey, how many out of 240 band members would prefer listening to jazz music?
A. 65
B. 90
c. 144
d. 175
Answer:
B.) 90
Step-by-step explanation:
Since the ratio is 3:8, the fraction would look something like the following.:
[tex]\frac{3}{8} =\frac{?}{240}[/tex]
We know that there are 240 band members in this scenario. What do you multiply 8 by to get 240? 30.
[tex]\frac{3*30}{8*30} =\frac{90}{240}[/tex]
To solve the problem, we set up a proportion, 3/8 = x/240. Solving for 'x', we find that 90 out of 240 band members would prefer listening to jazz music, so the correct answer is B (90).
Explanation:This problem concerns proportions. In the survey, it is stated that 3 out of 8 band members preferred listening to jazz. To find out how many out of 240 would prefer jazz, we set up and solve a proportion. Our proportion is 3/8 = x/240, where 'x' is the number of band members we need to find.
To solve for 'x', we cross-multiply 3*240 = 8x. This gives 720 = 8x. Then divide by 8, and we get x = 90. So, 90 out of 240 band members would prefer listening to jazz music.
Therefore, option B (90) is correct.

Debra has two scarves. One is square and each side is 32 inches long. The other is rectangular and is 48 inches long and 20 inches wide. Which statements about the two scarves are correct? Choose all that apply.
The question asks about the geometrical properties of two scarves, one square and one rectangular. The area of the square scarf is 1024 square inches and that of the rectangular one is 960 square inches. Additionally, the square scarf has a side length of 32 inches and the rectangular scarf has lengths of 48 and 20 inches.
Explanation:The subject of the question being asked is Mathematics. Specifically, it deals with the concepts of area and perimeter for square and rectangular shapes. For the square scarf, since all sides are equal and each one is 32 inches, we calculate its area by squaring one side (32*32), yielding an area of 1024 square inches. Its perimeter (the total length of the boundary) is 4*32 i.e., 128 inches.
For the rectangular scarf, its area is determined by the formula length*width, so 48*20 equals 960 square inches. Its perimeter is the sum of all sides (2*length + 2*width) equates to 2*48+2*20 = 136 inches.
Therefore, looking at the given options, the statement regarding both the area and the length of a side (option d) is correct, as we computed the area and side length for both scarves, along with the incorrect calculations provided.

By what percent will the product of two numbers decrease if one of them is decreased by 20% and the other is decreased by 60%?
Answer:
We have:
P1 = a x b
If a decreases by 20% and b decreases by 60%, then we have:
P2 = a x (100 - 20)/100 x b x (100 - 60)/100
= a x 80/100 x b x 40/100
= a x b x 8/25
=> P1 - P2 = ab - (8/25)ab = (17/25)ab
=> If a decreases by 20% and b decreases by 60%, product of a and b would decrease 17/25 = 0.68%

A square floor tile has a diagonal that is 19 inches long. If x is the length of a square, write an equation that shows the relationship between the lengths of the sides and the diagonal.
The equation that shows the relationship between the lengths of the sides and the diagonal is 2[tex]x^2[/tex] = [tex]d^2[/tex] where x is the length of the side and d is the length of the diagonal.
In a square, the diagonal divides the square into two congruent right triangles. By the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the lengths of the other two sides.
Let x be the length of one side of the square, and d be the length of the diagonal. According to the Pythagorean theorem, we have:
[tex]\[ x^2 + x^2 = d^2 \][/tex]
Simplifying:
2[tex]x^2[/tex] = [tex]d^2[/tex]
This equation represents the relationship between the length of the sides (x) and the length of the diagonal (d) of the square tile.

On your own paper, graph the coordinates of quadrilateral ABCD.
● A(-3, 0)

● C(6, -1)
● D(1, -5)
A) Identify what type of quadrilateral ABCD will be and give an explanation of your response. You must also justify it algebraically by showing your work to support your response.
B) What is the perimeter and area of quadrilateral ABCD?
Answer:
A) Square
B) Perimeter: 4sqrt(41) units
Area: 41 units²
Step-by-step explanation:
AB and CD are parallel because both have the same gradient:
AB: (-3-2)/(0-4) = 5/4
CD: (6-1)/(-1--5) = 5/4
AD and BC are parallel because both have the same gradient:
AD: (-3-1)/(0--5) = -4/5
BC: (6-2)/(-1-4) = -4/5
Since (5/4) × (-4/5) = -1
All angles are 90 (Perpendicular)
Lengths
CD = AB = sqrt[(-3-2)²+(0-4)²] = sqrt(41)
BC = AD = sqrt[(6-2)²+(-1-4)²] = sqrt(41)
Therefore all sides are equal in length
Hence it's a square
Perimeter = 4s = 4sqrt(41) units
Area = s² = [sqrt(41)]² = 41 units²
