Answer:
(a - b)(5x - 2y)
Step-by-step explanation:
Given
5x(a - b) - 2y(a - b) ← factor out (a - b) from each term
= (a - b)(5x - 2y) ← in factored form
The polynomial 5x(a-b)-2y(a-b) can be factored into (a-b)(5x-2y). This is achieved by taking out the common factor of (a-b) from both terms.
Explanation:To factor the polynomial
5x(a-b)-2y(a-b)
, you first notice that the terms have a common factor, (a-b). Factoring is a process where you write the expression as a product of its factors. In this case, you can pull out the common factor from both terms. This leaves you with
(a-b)(5x-2y)
. So, the factored form of the given polynomial is (a-b)(5x-2y). By applying the distributive property, you can check your work: (a-b)*5x gives the first term and (a-b)*(-2y) gives the second term, confirming the factored form is correct.

The ratio of a right angle to the total degrees in a circle is
Select one:
a. 1:2
b. 1:4
c. 1:3
d. 1:5
The ratio of a right angle to the total degrees in a circle is 90:360, which simplifies to a ratio of 1:4.
The ratio of a right angle to the total degrees in a circle can be found by comparing the degree measures of each. A right angle is 90 degrees, and a full circle is 360 degrees.
Therefore, the ratio of a right angle to the total degrees in a circle is 90:360.
When simplifying this ratio, we divide both terms by 90, the degree measure of the right angle, which gives us 1:4.
Hence, the ratio is simplified to 1:4.

I don't want to write the whole thing for you since that would be plagiarism for you to take, but be sure to include these key points:
One cone is oblique.
The cones have different slant heights.
The lengths of all corresponding edges are not equal.
Congruent cones must have congruent corresponding measures, including slant height.
Hope this helps!
The two cones are congruent because they have the same radius, height, and volume - all factors that determine a cone's size and shape.
Explanation:Yes, the two cones are congruent. In mathematics, two shapes are considered congruent when they have the exact same size and shape. When it comes to cones, this means that they possess the same radius and height. Since the question states that both the radius and height of the two cones are the same, we can deduce that the cones are congruent. The volume of a cone is determined by its radius and height (V=1/3πr²h) and since this is also the same for the two cones, it backs up the claim of congruency.

Clint found the area of the parallelogram shown. Which statement explains the error Clint made?
A parallelogram with a base of 11 centimeters, height of 4 centimeters, and side length of 5 centimeters.
Clint’s Work:
A = (b) (h). A = (11) (5). A = 55 centimeters squared.
a.Clint used the wrong units. He should have used cm, as that is what was in the diagram.
b.Clint used the wrong formula. He should have used A = one-half b h.
c.Clint did not use all three numbers in the diagram. He should have multiplied them all.
d.Clint did not use a height perpendicular to the base. He should have used 4 for the height.
Answer:
D
Step-by-step explanation:
like it said, he used 5 instead of the actual height which is 4
Answer:
D
Step-by-step explanation:
The area of a parallelogram is denoted by: [tex]A=bh[/tex] , where b is the base and h is the height that is perpendicular to the base. Depending on what kind of parallelogram it is (square, rectangle, rhombus, regular parallelogram), that height could be the side length, but usually it is not; it is only the side length in special cases, like a square.
Here, we are given that the base is 11 and that the height is 4. Since the problem gives us two different values for the height versus the side length, we know that for this parallelogram, the height is not the same as the side length. Thus, we must use 4 for the height and 11 for the base in the area formula.
Therefore, the only answer that correctly points out this mistake is D.

The square of a positive number increased by twice the number equals three. Find the number
Answer:
1
Step-by-step explanation:
Let the number be x
x² + 2x = 3
x² + 2x - 3 = 0
Product = -3
Sum =2
Factors = 3 * (-1)
x² + 3x - x - 3 = 0
x*(x+3) - (x + 3) = 0
(x + 3)(x - 1) = 0
Ignore x + 3 because the number is a positive number
x - 1 = 0
x = 1
The number is 1
What do you get when you subtract 9 from b?
When you subtract 9 from the variable "b," you get the expression:
b - 9
When you subtract 9 from the variable "b," you are performing a basic arithmetic operation in algebra. This subtraction results in a new value, which is b decreased by 9 units. In mathematical terms, it can be represented as:
b - 9
This expression represents the concept of taking a quantity, "b," and reducing it by 9. The result will depend on the specific value of "b." For example, if b = 15, then b - 9 would equal 6. If b = 20, then b - 9 would equal 11. In essence, subtracting 9 from "b" simply means subtracting 9 from the value represented by "b," whatever that value may be.

A tent company makes one type of tent that is shaped like a triangular prism. The approximate dimensions are 5ft, 6ft, 9ft and 5.5ft. Based on these dimensions, how much fabric is needed to make one tent, including floor.
Given:
The base of the triangle = 6 ft
The height of the triangle = 5 ft
The other two side of the triangle = 5.5 ft and 5.5 ft
The height of the prism = 9 ft
To find the measurement of the fabric to make the tent.
We need to find the surface area of the triangular prism.
Formula
The surface area of the triangular prism is
[tex]SA = bh+(a+b+c)H[/tex]
where, b be the base of the triangle
h be the height of the triangle
a and c be other two sides of the triangle
H be the height of the prism
Now,
Putting,
b = 6, h = 5, a = 5.5, c = 5.5 and H = 9 we get,
[tex]SA = (5)(6)+(6+5.5+5.5)(9)[/tex] sq ft
or, [tex]SA = 30+153[/tex] sq ft
or, [tex]SA = 183[/tex] sq ft
Hence,
Based on the given dimension 183 sq ft fabric is needed to make the tent.

68+51=119
A=180-119=61
180-61=119
B=119
Answer:
∠ B = 119°
Step-by-step explanation:
∠ C and 112° are adjacent angles and supplementary, thus
∠ C = 180° - 112° = 68°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ B is an exterior angle of the triangle, thus
∠ B = 51° + ∠ C = 51° + 68° = 119°

Answer:
5) 27/70
6) 90
Step-by-step explanation:
5) The first step in this problem is to figure out the amount of total spins. To do so, add up all of the numbers in the column "Frequency".
18 + 15 + 27 + 10 = 70.
Now, look at the amount of times the spinner landed on green. This is 27 times. So, the ratio of green spins to total spins is 27:70, or 27 out of 70 spins. Converting this to a fraction, we get the final answer, 27/70.
6) To solve this problem, we have to first do the same steps as the previous problem, but with the color red. There are 70 total spins, and 18 red spins. Therefore, the ratio is 18:70. However, this problem wants the total number of spins to be 350. In other words, 70 needs to become 350. To do this, multiply each side of the ratio by 5. The ratio becomes 90:350. Using this ratio, we can determine that a solid prediction is 90 red spins out of 350 total spins.
Answer:
5) 27/70
6) 90
