Keelie has a triangular-shaped card. The lengths of its sides are 3.9 cm, 5.2 cm, and 6.5 cm. Is the card a right triangle?
Answer:
Yes
Step-by-step explanation:
Since the longest side is 6.5 cm, so let it be hypotenuse c.
Verifying by right angle formula
c^2=a^2+b^2
(6.5)^2=(3.9)^2+(5.2)^2
42.25=15.21+27.04
42.25=42.25
Hence the given triangle is a right angles triangle
let x be an integer that satisfies x^4 + 24 = 105. what is the value of x^2 - 24?
Answer: -15
Step-by-step explanation:
[tex]x^{4}[/tex] + 24 = 105
subtract 24 from both sides of the equation .
[tex]x^{4}[/tex] = 105 - 24
[tex]x^{4}[/tex] = 81
find the fourth root of both sides
x = 3
Therefore : substitute x = 3 to find the value of [tex]x^{2} -24[/tex]
[tex]x^{2}[/tex] - 24 = [tex]3^{2}[/tex] - 24
= 9 - 24

which is a better buy: 50 head of cattle for $24,500 or 37 head of cattle for $18,870?
Let us see...
50 head of cattle = 24,500
Divide everything by 50: 1 head of cattle = $490
37 head of cattle = 18,870
Divide the entire equation by 37: 1 head of cattle = $510
The second choice would cost a person $20 more than the first choice, so 50 head of cattle for $24,500 is a better buy.

9. A parallelogram is a quadrilateral.
True or False?
Answer:
YES
Step-by-step explanation:
Quadrilateral have 4 sides and their sum of angles is 360 and parallelogram also have 4 sides and sum of angles is 360
Final answer:
The statement that a parallelogram is a quadrilateral is true. A parallelogram is a type of quadrilateral with parallel opposite sides, and its properties are related to the parallelogram law in vector addition.
Explanation:
A parallelogram is indeed a type of quadrilateral with two pairs of parallel sides. In geometry, quadrilaterals are four-sided polygons, and parallelograms are a specific class within that category. Furthermore, in the context of vector addition, the parallelogram law shows how two vectors can combine to form the sides of a parallelogram. This law is closely related to the triangle law of vector addition as both can depict how vectors combine.
An example of the parallelogram's properties in advanced concepts would be where two objects at rest have world-lines that define a rectangle which may become a parallelogram in a different frame of reference. Additionally, the concept of vectors is also relevant when discussing the diagonals of a rhombus, which is a special type of parallelogram with all sides equal in length. Using vectors and their scalar products, it can be shown that the diagonals of a rhombus are always perpendicular to each other.

James spent half of his weekly allowance on clothes. To earn more money his parents let him clean the oven for $8. What is his weekly allowance if he ended with $15.
Answer: 14
Step-by-step explanation: If you add 7 to 8 you get 15 so if he spent half of his allowance you multiply 7 by 2 so your answer is 14.
James's weekly allowance is calculated by setting up an equation based on the information given. After spending half of his allowance on clothes and earning an additional $8, the equation 0.5A + $8 = $15 is solved to reveal that James's weekly allowance is $14.
The student's question involves solving for James's weekly allowance, given that he spent half of it on clothes and earned an additional $8 by cleaning the oven, which resulted in him having a total of $15 at the end. To solve the problem, we need to set up an equation where 'A' represents James's weekly allowance.
James spent half of his allowance on clothes, which means he has half of it left. So, we can represent this as 0.5A. Then he adds $8 from cleaning the oven: 0.5A + $8 = $15. We isolate 'A' by subtracting $8 from both sides of the equation: 0.5A = $15 - $8, which simplifies to 0.5A = $7. To find the full value of his allowance (A), we divide by 0.5: A = $7 / 0.5, so A = $14.
Thus, James's weekly allowance is $14.

150 grams of zinc is present
Solution:
Given that, ratio of zinc to copper is 3 to 13
A jar of the chemical contains 650 grams of copper
From given information,
zinc : copper = 3 : 13
Let the zinc present be 3x
Let the copper present be 13x
Given that, jar contains 650 grams of copper
13x = 650
x = 50
Substitute x = 50 in 3x
Zinc present = 3x = 3(50) = 150
Thus it contains 150 grams of zinc

Three national news networks are trying to estimate what percentage of
American voters support a particular presidential candidate. To estimate the
population parameter, each of the three networks collect data from a simple
random sample of voters. Here are the numbers of voters in the networks
random samples:
• Network A: 1500 voters sampled
• Network B: 1250 voters sampled
• Network C: 1800 voters sampled
Which sample is likely to have the least variability?
O
A. The Network A sample
O
B. The Network B sample
O
C. The Network C sample
Answer:
Option C. The Network C sample.Explanation:
The variability of a sample may be described by using some common statistics like the variance and the standard deviation.
The variance and the standard deviation measure the difference between the values of the data and the mean. The variance is the average square of those differences or deviations. The standard deviation is the square root of the variance.
Thus, both variance and deviations, being an average of the differences of the data from the mean contain the number of data in the denominator of the equation.
That lets you know to conclude that the larger the number of data (the larger the sample) the smaller the variance and the standard deviation, this is the lower the variability of the data.
Hence, Network C, which has the greatest number of voters sampled (1,800) is likely to have the least variability.

The ratios of the angles in ABC is 3:5:7. Find the
measure of the angles.
The smallest angle is
So you have a diagram or picture of the triangle?
Anyways...
Answer: 36
Explanation:
3:5:7 is the ratio of the triangle's angles
The sum of all angles = 180 degrees.
3 + 5 + 7 = 15
Lets assume 'a' is the smallest angle with the ratio of 3
b is the second largest with a ratio of 5
And c is the largest angle with the ratio of 7
In other words:
a + b + c = 180
For 15 to get to 180 => 180 ÷ 15 = 12
So 15 × 12 = 180
So for 3 to get to a => 3 × 12 = 36
Thus the smallest angle is 36 degrees
Answer:s
The three angles are 36, 60, and 84 degrees
Smallest angle is 36 degrees
======================================================
Explanation
The ratio 3:5:7 is equivalent to 3x:5x:7x as we can multiply all parts of any ratio by the same number, and still have it be the same ratio.
So we can think of the three angles as 3x, 5x, 7x
Add up those angles. Set them equal to 180 and solve for x.
3x+5x+7x = 180
15x = 180
x = 180/15
x = 12
Use this x value to find the three angle measures
3x = 3*12 = 36
5x = 5*12 = 60
7x = 7*12 = 84
As a check, add up the angles to get: 36+60+84 = 180
So the answer is confirmed.

7=|3x+9|+7
Answer:
[tex]x=-3[/tex]
Step-by-step explanation:
Given the equation
[tex]7=|3x+9|+7[/tex]
1. Use Addition property of equality, add -7 to both sides:
[tex]7-7=|3x+9|+7-7\\ \\0=|3x+9|[/tex]
2. The absolute value of the number is 0 if and only if the number is 0, so
[tex]3x+9=0[/tex]
3. Use Addition property of equality, add -9 to both sides:
[tex]3x+9-9=0-9\\ \\3x=-9[/tex]
4. Use Division property of equality, divide both sides by 3:
[tex]\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3[/tex]
The solution is x = -3.
To solve the equation 7 = |3x + 9| + 7, let us follow these steps:
First, we simplify absolute value expression:
7 = |3x + 9| + 7
0 = |3x + 9|
The absolute value of a number is zero only when the number itself is zero. So, we set the expression inside the absolute value equal to zero:
3x + 9 = 0
3x = -9
x = -3
The solution to the equation is x = -3.
Find the magnitude and direction of -5i + 10j

Given expression: 21 + (36 + 0 + 19)
Using identity property of addition: a + 0 = a
21 + (36 + 0 + 19) = 21 + (36 + 19)
Using commutative property of addition: a + b = b + a
21 + (36 + 19) = 21 + (19 + 36)
Using associative property of addition: a + (b + c) = (a + b) + c
21 + (19 + 36) = (21 + 19) + 36
Now, add two numbers inside the bracket.
(21 + 19) + 36 = 40 + 36
Using closure property of addition: a + b = c any number.
40 + 36 = 76
Hence 21 + (36 + 0 + 19) = 76.
What is -15x + 80 > 170
Answer:
Step-by-step explanation:
Value of x should be less than (-6).
x = { .......,-9,-8,-7}
For example:
-15*-7 +80 = 105+80 = 185 >170
The solution to the inequality -15x + 80 > 170 is x < -6. We subtract 80 from both sides and then divide by -15, remembering to reverse the inequality sign.
Explanation:The question provided asks for the solution to the inequality -15x + 80 > 170. To solve the inequality, we can follow these steps:
Subtract 80 from both sides to get -15x > 90.Divide both sides by -15 to solve for x, remembering that dividing by a negative number in an inequality reverses the inequality sign, resulting in x < -6.Therefore, the solution to the inequality is all values of x that are less than -6.

Is the centroid of a triangle, the center of the circle cirumdcribing it?
Answer:
No
Step-by-step explanation:
No, only if the triangle is a right triangle.
Final answer:
No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid and circumcenter are distinct points that coincide only in equilateral triangles.
Explanation:
No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid is the point of intersection of the medians of the triangle, which are the lines connecting each vertex to the midpoint of the opposite side. On the other hand, the circumcenter of a triangle is the center of the circle that passes through all three vertices of the triangle.
In some cases, the centroid and circumcenter might coincide, but this happens only when the triangle is equilateral. In all other cases, the centroid and circumcenter are distinct points.
For example, an equilateral triangle has its centroid and circumcenter at the same point. However, in an isosceles triangle, the centroid will lie on the line segment connecting the midpoint of the base to the opposite vertex, while the circumcenter will lie on the perpendicular bisector of the base.
