130+ ? + (180-160) = 180
130+ ? +20= 180
150+ ? = 180
? = 30°
the missing angle is 30°
4 t-shirts and a hat costs £26.00
A t-shirt and a hat costs £8.00.
How much does a t-shirt cost?
How much does a hat cost?
Answers
Hat $10.00
A t-shirt and hat is $8.00 you can divide that by 2 and you get 4. So it will be $4.00
$4.00 times 4 =$16.00 for T-Shirt
So that will mean that the hat is $10.00
And $16.00+$10.00=$26.00
That’s what I got so far
T-shirt: £6
Hat: £2
Lets say t-shirts are ‘a’ and hats are ‘b’
4a + b = 26 and a + b = 8
In an equation:
|4a + b =26
|a + b =8
Now I’m canceling the ‘a’ in the equation so I can solve for b
I’m going to multiply the ‘a’ in the bottom by -4 so if I add it to the ‘4a’ it’ll be equal 0
I can’t only multiply the ‘a’, I have to multiply the whole bottom part:
|4a + b =26
-4 |a + b =8
And now:
|4a + b =26
|-4a -4b =-32
We got rid of the a in the equation
4a-4a=0
b-4b=-3b
26-32=-6
-3b=-6
And b=2
Now we’ll go back to the original equation and replace ‘b’ with its value to solve for ‘a’
|4a + 2 =26 ==> 4a=26-2
|a + 2 =8 ==> a=8-2
4a=24
a=6
Therefore, a T-shirt cost £6 and a hat cost £2.

Find the measure of the indicated aces and angles
Answers
Answer:
a=21
b=69
c=42
d=138
Step-by-step explanation:
c is supplementary to d (which is 138), so c=180-138= 42.
angle b is on the edge of the central angle 138, so b is 1/2, therefore, b=69.
angle a is complementary to angle b because any triangle that includes the diameter is a right angle, so angle a=90-69=21.
Solve the equation: 12 - x (x - 3) = (6 - x)(x + 2)
Answers
Answer: the answer is 0
Why 0?:
Step 1: Simplify both sides of the equation
-x * x= -x²
-x * -3= 3x all together it is ( -x²+3x+12)
for the other side:
-x * x= -x²
6 * x= 6x and x * 2= 2x and 6 * 2= 12
then subtract 6x-4x= 2x so final would be = −x²+4x+12
Step 2: Add x² to both sides.
−x²+3x+12+x²=−x²+4x+12+x² then we are left with 3x+12=4x+12
Step 3: Subtract 4x from both sides.
3x+12−4x=4x+12−4x --> −x+12=12
Step 4: Subtract 12 from both sides.
−x+12−12=12−12
−x=0
Step 5: Divide both sides by -1 or -x
x=0

f(x) = 1.8x - 10
g(x) = -4
so, for f(x)=g(x) that automatically means
1.8x - 10 = -4
1.8x = 6
x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3
What is the measure of DE?

Answers
Answer:
Option (B) is correct
Step-by-step explanation:
A dot plot with an axis marked from 0 to 10 at increments of 1 is shown. Plot shows 8 dots at 0, 7 dots at 1, 5 dots at 2, 4 dots at 3, 2 dots at 4, and 1 dot at 10.
A)
The mean is equal to the median and the data are symmetric.
B)
The peak is equal to the median and the data are skewed.
C)
The data are skewed and there is an outlier.
D)
The data are symmetric and there is an outlier.
Answers
Answer:
C) The data are skewed and there is an outlier.Step-by-step explanation:
Its clear from the dot plot that:
There is an outlier at 10, since majority of data are concentrated at 0-4 interval with only one far away.The data are skewed, since most data concentrated to one side of the median.So, the correct choice is C
The given information in the dot plot is,
i) An outlier is present at 10.
ii) The data's majority are concentrated at 0 to 4 interval.
iii) 10 is the only one, which is far away.
iv) We confirm that the data are skewed.
v) Because the most data is concentrated in one median's side.
Then the final answer will be,
C) The data are skewed and there is an outlier.
Therefore, option (C) is the answer.

Suggest methods (other than Cartesian Coordinates) of describing the location of points on a plane.
Answers
Answer:
There are two alternatives: (i) Polar coordinate system (a.k.a. Circular coordinate system), (ii) Elliptic coordinate system.
Step-by-step explanation:
There are two alternative ways of describing the location of points on a plane:
(i) Polar coordinate system (a.k.a. Circular coordinate system).
(ii) Elliptic coordinate system.
Now we proceed to explain briefly the characteristic of each option:
Polar coordinate system: [tex](r, \theta)[/tex]
Where:
[tex]r[/tex] - Distance of the point with respect to origin.
[tex]\theta[/tex] - Direction of the vector between origin and point with respect to the +x semiaxis, in sexagesimal degrees.
The formulae for each component in terms of Cartesian coordinates are described below:
[tex]r = \sqrt{x^{2}+y^{2}}[/tex] (1)
[tex]\theta = \tan^{-1} \frac{y}{x}[/tex] (2)
Elliptic coordinate system: [tex](\mu, \nu)[/tex]
Where [tex]\mu[/tex] and [tex]\nu[/tex] are elliptical coordinates.
The formulae for each component in terms of Cartesian coordinates are described below:
[tex]x = a\cdot \cosh \mu \cdot \cos \nu[/tex] (3)
[tex]y = a \cdot \sinh \mu \cdot \sin \nu[/tex] (4)
Where [tex]a[/tex] is the distance between origin and any of the foci along the x axis.

This is a right triangle trig problem. Picture a right triangle. The height of the triangle is the height of the lighthouse, your distance from the base of the lighthouse is what we are solving for, and the reference angle is 2 degrees, which is the angle of inclination from where you stand to the top of this lighthouse. We have the reference angle, the side opposite the reference angle, and we are looking for the side adjacent to the reference angle. This is the tangent ratio: the side opposite the reference angle over the side adjacent to the reference angle. We know the measure of the reference angle and we know the value of the side opposite the reference angle. Filling in:
