Answer:
(x+8)(x+11)
Step-by-step explanation:
When you factor a quadratic by the form:
[tex]x^{2} + bx + c[/tex]
you are looking for two numbers, 'q' and 'r', which ADD to 'b' and MULTIPLY to 'c'.
In this case, some example numbers that multiply to 88 are:
±1, ±2, ±4, ±8, ±11, ±44, ±88.
Since they must add to 19, then you can figure out through some trial and error that the numbers are 8 and 11.
8*11 = 88
8+11 = 19
So, the answer is (x+8)(x+11)
If the lengths of the two legs of a right triangle are 12 and 16, what's the length of
the hypotenuse?
A) 28
B) 14
C) 16
D) 20
Answer:
c=20cm
Step-by-step explanation:
In a right triangle
a^2 +b^2 =c^2
Where c is length of hypotenuse.
⟹12^2 +16^2 =c^2
c^2 =144+256
c^2 =400
c=20cm

A vessel without a lid has the shape of a cylinder. The height of the vessel is 1.5 m, and the diameter of the base represents 40% of the height. Determine if 1 kg of paint is enough to completely paint the vessel inside and out, if it is known that for 1 square meter of surface 150g of paint is consumed.
Answer:
Yes, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.
Step-by-step explanation:
For the given vessel without a lid,
diameter = 0.4 x 1.5
= 0.6 m
radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{0.6}{2}[/tex]
= 0.3 m
Total external surface area of the vessel = 2[tex]\pi[/tex]rh + [tex]\pi[/tex][tex]r^{2}[/tex]
= [2 x [tex]\frac{22}{7}[/tex] x 0.3 x 1.5] + [[tex]\frac{22}{7}[/tex] x [tex](0.3)^{2}[/tex]]
= 2.8286 + 0.2829
= 3.1112
Total external surface area of the vessel is 3.1112 square meter.
Total internal and external surface area = 2 x 3.1112
= 6.2224 [tex]m^{2}[/tex]
But for 1 square meter, 150 g of paint is consumed. Thus;
for 6.2224 [tex]m^{2}[/tex] = 6.2224 x 150 g
= 933.36 g
Thus, 6.2224 [tex]m^{2}[/tex] of area would require 933.36 g of paint.
So that,
[tex]\frac{933.36}{1000}[/tex] = 0.93336 kg
Therefore, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.

Choose the number that is 7.648 rounded to the nearest hundredth
Answer:
7.65
Step-by-step explanation:
because 4 is the hundredths place so you look to the right and the number 8 is more so you round it and you get 5 so its 7.65
The number that equivalent to after rounding off to nearest hundred will be 7.65 .
Given,
Number = 7.648
Here,
The concept of rounding off:
When the digit after decimal is greater than 5 then it can be rounded off to its next value .
If the digit is less than 5 then it can be rounded to its previous value .
So,
The number is 7.648 .
Rounding off to its nearest hundred .
Clearly we can round off the number to its nearest hundred ,
Rounding off to nearest hundred= 7.65

Answer:
24°
Step-by-step explanation:
[tex]r \degree = 180 \degree - (34 + 122) \degree \\(vertical \: \angle s) \\ \\ r \degree = 180 \degree - 156 \degree \\ \\ r \degree = 24 \degree \\ \\ r = 24[/tex]
Answer and Step-by-step explanation:
The answer is 24 degrees.
We see the angle 34 and 122. To find that angle in between, we subtract those numbers from 180.
180 - 34 - 122 = 24 = r
By the vertical angles theorem, r is equal to 24.

Which of the the coordinates is equal to sin (4pi/5) ?
A) x-coordinate of point A
B) y-coordinate of point A
C) x-coordinate of point B
D) y-coordinate of point B
E) x-coordinate of point C
F) y-coordinate of point C
Answer:
Step-by-step explanation:
π/2 < 4π/5 < π
4π/5 is in Quadrant II
sin(4π/5) = y-coordinate of A
The coordinates is equal to sin(4π/5) = y-coordinate of A.
We need to find the coordinates is equal to sin (4pi/5).
Which trigonometric functions are positive in which quadrant?In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Then, we have π/2 < 4π/5 < π
So, 4π/5 is in Quadrant II
Hence, the coordinates is equal to sin(4π/5) = y-coordinate of A.

The price of a cycle after allowing 15% discount and 13% VAT is Rs.19,323. Find the amount of VAT levied and marked price.
Answer:
Rs. 18936.54
Step-by-step explanation:
Given data
Discount=15%
VAT= 13%
Amount paid= Rs.19,323
The amount of VAT
=13/100*19323
=0.13*19323
= Rs. 2511.99
The amount of discount
=15/100*19323
=0.15*19323
= Rs.2898.45
The marked price is
=19323+2511.99-2898.45
=21834.99-2898.45
=Rs. 18936.54

Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate.
a = 8.1 in.
b = 13.3 in.
c = 16.2 in.
A = 31.9°, B = 52.8°, C = 95.3°
No triangle satisfies the given conditions.
A = 29.9°, B = 54.8°, C = 95.3°
A = 27.9°, B = 54.8°, C = 97.3°
I think it might be B
Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°

Answer: $4110.8 (more likely - 95% sure) or $2,107 (less likely)
Step-by-step explanation: It could be $4110.8 because you have the take the total they made and subtract is from the cost of the toys ($7,230-$2,450=$4,780). Then you have to take the result of that and get 14% of it, then subtract that from the $4,780 amount. Then you get the final answer which is $4110.8.
However, it could also be $2,107 because the question itsn't that clear in the second sentence. It could be saying that $2,450 is the price of the toys (which is what I assumed above), or that it is the profit that the $2,450 (which I used below). I think that the above answer is more likely because if not then the first number would never be used. Anyways here is the second way it could be.
Step-by-step explanation: It could be $2,107 because you take the profit ($2,450) and get 14% of it, then subtract that from the $2,450 amount. Then you get the final answer which is $2,107.
If I was you, I would do the first one ($4110.8) because I really think it is that one. I just put the other one here just in case.
Liam has $62. He saves an equal amount of money each week for 6 weeks. Now he has $110. How much money did Liam save each week?
Answer:
Step-by-step explanation:
Liam saved $8 each week for 6 weeks.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's represent the amount of money Liam saves each week as x.
According to the problem, Liam saves an equal amount of money each week for 6 weeks, so the total amount he saves is 6x.
If we add this to the amount he started with, we get the total amount he has now: 6x + 62.
We also know that he now has $110, so we can set up an equation:
6x + 62 = 110
Subtracting 62 from both sides gives:
6x = 48
Dividing both sides by 6 gives:
x = 8
Therefore,
Liam saved $8 each week for 6 weeks.
