Answer:
The expression is not factorable with rational numbers
Step-by-step explanation:
a²-10a+24+6b-9b²
(a-6)(a-4)+3b(2-3b) but this is incorrect
Therefore, the expression is not factorable with rational numbers
In the triangle ABC
are drawn two sides
of it, BB1 and AA1.
Those half-edges
intersect at point O.
What is the length of
the semicircular BB1
if B10 = a cm?
Answer:
3a
Step-by-step explanation:
What we have as the point O refers to the centroid of the triangle
The centroid splits the distance between the opposite vertex and the middle of the side length that faces it into two; with the longer side being twice the length of the shorter
So what we have here is that;
B1O is half the length of BO
So, if B1O is a cm, BO would be 2a
So we have the entire side length measure as;
a + 2a = 3a

Angelo drew a scale model of the flagpole at school. If the actual pole is 15 feet tall, and his drawing is 10 inches tall, what scale did he use?
Answer: [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Given
Angelo drew a model with his drawing length 10 inches tall
The actual pole length is 15 feet tall
drawing scale is the ratio of drawing length to the actual length i.e.
[tex]\Rightarrow \text{Scale used l=}\dfrac{10}{15}\\\\\Rightarrow l=\dfrac{2}{3}[/tex]

Triangle ABC is similar to triangle DEF. What is the value of x ?
Answer:
A
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DF}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{45}{x+8}[/tex] = [tex]\frac{30}{25}[/tex] ( cross- multiply )
30(x + 8) = 1125 ( divide both sides by 30 )
x + 8 = 37.5 ( subtract 8 from both sides )
x = 29.5 → A

Sales Tax: At the movie theater, a bucket of popcorn costs $8.00 and a soda costs $2.50. How much will you pay in sales tax if the rate is 6%?
We have to pay $0.63 sales tax if the rate is 6%.
What is the sales tax?
Sales tax is a tax that is added to the price of goods or services when they are sold. It is typically a percentage of the purchase price and is collected by the seller from the buyer.
In this case, the price of the bucket of popcorn is $8.00 and the price of the soda is $2.50. If the sales tax rate is 6%, the total amount of sales tax paid on the popcorn would be $8.00 x 6/100 = $0.48 and on soda is $2.50 x 6/100 = $0.15. So the total amount of sales tax paid on both items is $0.48 + $0.15 = $0.63
Hence, we have to pay $0.63 sales tax if the rate is 6%.

find the area of the shaded region. Use 3.14 for pi
Answer:
This shaded region is consisted of 2 shapes: a right triangle and a semi-circle. To find the overall area, we must first find the are of the 2 shapes and add them together.
Step-by-step explanation:
1. Find the area of the right triangle:
a = 14, b = 2r = 8cm
A1 = ab/2 = 112/2 = 56cm²
2. Find the area of the circle:
r = 4 cm
A2 = πr² = 3.14 × 4² = 50.24cm²
3. Divide the area of the circle to get the area of the semi-circle:
A3 = A2/2 = 50.24/2 = 25.12cm²
4. Add the areas of the right triangle and the semi-circle together:
A1 + A3 = 56 + 25.12 = 81.12cm²

Gcf difference of square (trinomials (xmethod)
Help with math problem
9514 1404 393
Answer:
A) difference of squares
B) GCF
C) trinomials (X method)
Step-by-step explanation:
When a binomial is a difference of squares, factoring using the "difference of squares" method is appropriate.
The first binomial is ...
(2x)² -5² . . . . . a difference of squares
= (2x -5)(2x +5)
__
When the binomial is not a difference of squares, but there is a common factor, then the GCF method is appropriate.
2x³ -4x² = 2x²(x -2) . . . . . GCF method
__
When the expression is a trinomial, often the X method can work for factoring it.
x²-5x +6 . . . . 2 numbers are needed that sum to -5 and are factors of 6
6 = (-2)(-3), so the factorization is (by X method)
(x -2)(x -3)

The volume of a cone-shaped hole is 25 pi ft cubed . If the hole is 3 ft deep, what is the radius of the hole?
Answer:
5ft
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Volume = 25π ft cubed
Depth = 3 ft
So, we can calculate the radius by using following formula,
V = 1/3 ×π ×radius squared×depth
25π = 1/3×π×radius squared ×3
Radius squared = 25
Radius = √25
Radius = 5 ft
Hence the radius of the hole is 5 ft.
