Answer:
Step-by-step explanation:
x+y=10
x=10-y
x=10-5
x=5
3y= -3x+30
3(10-y)= -3(10-y)+30
30-3y= -30+3y+30
30+30-30=6y
30=6y
y=5

What does a obtuse angle look like .
Answer:
An obtuse angle is more than 90°. We know that a 90° angle, also known as a right angle, is in the shape of an "L".
So, an obtuse angle looks wider than an "L".

Answer:
S(-2,12)
y= -2(x+2)²+12
Location of coordinate axes:
y=0 → x= -2±√6 (-2-√6,0) (-2+√6,0)
x=0 → y=4 (0,4)
12 + x/4 > 20
Thank you if you answer!! please just put the answer
Answer:
The answer is x > 32.
Step-by-step explanation:
1) Subtract 12 from both sides.
[tex] \frac{x}{4} > 20 - 12[/tex]
2) Simplify 20 - 12 to 8.
[tex] \frac{x}{4} > 8[/tex]
3) Multiply both sides by 4.
[tex]x > 8 \times 4[/tex]
4) Simplify 8 × 4 to 32.
[tex]x > 32[/tex]
Therefor, the answer is x > 32.

this is all on you i cant do thatXD
Step-by-step explanation:
A fruit stand has 200 apples. They order 19 bags with 12 apple each. They sell 42 bags that have 8 apples each. The owner says they now have about 120 apples.
Is the owner's estimate reasonable?
The owner’s answer is reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 fewer apples than they started with.
The owner’s estimate is not reasonable. They ordered about 320 apples and sold about 240 so they should have about 80 more apples than they started with.
The owner’s estimate is reasonable. They ordered about 240 apples and sold about 320 so they should have about 80 fewer apples than they started with.
The owner’s estimate is not reasonable. They ordered about 240 apples and sold about 240 so they should have about the same number of apples as they started with.

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.

find the factors of each number. Write the common factor ( CF ) and then state the greatest common factor ( GCF) .
Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are
[tex]12=2\times 2\times 3[/tex]
[tex]21=3\times 7[/tex]
From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.

Answer:
63
Step-by-step explanation:
A triangle always has a total of 180 degrees
Since we know two we can solve for x
76+41+x=180
x=63
Answer:
63
Step-by-step explanation:
Basically there is 180 degrees in every triangle. So all you do is
180-76=104
104-41= 63
so your answer is 63 degrees.

Answer:
I. The width is 43.5 inches.
II. The length is 24.5 inches.
Step-by-step explanation:
Let the length and width of the rectangle be L & W respectively.
Given the following data;
Perimeter of rectangle = 136 inches
Translating the word problem into an algebraic expression, we have;
L = W - 19 ......equation 1
Perimeter of rectangle = 2(L + W) ......equation 2
To find the dimensions of the rectangle;
136 = 2(L + W)
Substituting eqn 1 into eqn 2, we have;
136 = 2(W - 19 + W)
136 = 2(2W - 19)
136 = 4W - 38
4W = 136 + 38
4W = 174
W = 174/4
W = 43.5 inches
To find the length;
L = W - 19
L = 43.5 - 19
L = 24.5 inches
It took the paramedics 840 seconds to arrive at the scene. How many minutes did it take for the paramedics to arrive? (Round to the nearest minute, if necessary.)
Answer:
14 min

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.
