Answer:
the third side must be greater than 6 but less than 16
Step-by-step explanation:
use triangle inequality theorem - 3 scenarios (one of which is discounted because it produces a negative and a side of a triangle cannot be negative)
5 + 11 > 3rd side (n) n < 16
5 + n > 11 n > 6
11 + n > 5; n > -6 discounted
If a triangle has three sides with the lengths 20, 16, and 12, what are the angles?
Answer:
angle a = 53.13°
angle b = 36.87°
angle c = 90°
Step-by-step explanation:
The following is one way to perform the calculation. It may not be the best way.
Calculates ∠A, ∠B, ∠C based on given a, b and c.
∠A = arccos( b2 + c2 - a2 2bc )
= 0.9273 rad = 53.13° = 53.13°
∠B = arccos(a2 + c2 - b2 2ac )
= 0.6435 rad = 36.87° = 36.87°
∠C = arccos(a2 + b2 - c2 2ab )
= 1.5708 rad = π/2 = 90°

What is the answer for 3/4g = -12
Answer:
Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\frac{3}{4}g=-12[/tex] and find the value of g
Solving:
[tex]\frac{3}{4}g=-12[/tex]
Multiply both sides of the equation by [tex]\frac{4}{3}[/tex] because we need to find value of g.
[tex]\frac{3}{4}g\times \frac{4}{3} =-12\times \frac{4}{3}\\g=-4\times 4\\g=-16[/tex]
So, we get g = -16
Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]

12 - y = 5
could you explain how to do it :]
Answer:
this is
12-y=5
12-y =5
y=5- 12
then y=7
could you see this this correct
Answer:
7
Step-by-step explanation:
do 12-5 which is 7
that is the answer
you need to find which number needs to be subtracted from 12 to make 5!
Explain the best you can because I’m struggling :)
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
The question is in the picture. I’ll appreciate it so much !! Thank you !!!

Which expression is equivalent to 3/32x8y10
Answer:
I think #2
Step-by-step explanation:
Please help I don’t understand
Answer:
1/2
Step-by-step explanation:
y = mx + b
the "m" is the slope
and the b is the y-intercept
as you can see from the equation y = 1/2x + 3
the 1/2 substituted the m which is the slope
so the slope of the line is 1.2
Hope this helped!

Answer:
The length is 6.875 (6.9) ft, the width is 5 ft, and the area is 34.375 (34.5) [tex]ft^{2}[/tex]
Step-by-step explanation:
If the scale is 4 in to 5 ft, we can simply divide 5 by 4 to find out the scale by which we would multiply one inch. The reason it is 5/4 and not 4/5 is because 5 ft > 4 in. 5/4 = 1.25. 1.25 * 5.5 = 6.875. When rounded to the nearest tenth, it is 6.9. Using the same measurement NOT rounded, it is 34.375, but using the rounded value the answer is 34.5 sqft.
Hope I helped! Also, if this is wrong someone please correct me.

Colin gets £x wages each week. After he pays his tax of £t, he
then pays his rent of £120. He shares what's left between
himself and his wife. How much do they each get?
Answer:
They will each get ;
(x-t)/2 - 60
Step-by-step explanation:
Here, we want to know the amount of money that Colin and his wife gets
we start by subtracting the necessary terms
Mathematically, that would be;
x-t-120
So what each of them get will be;
(x-t-120)/2
= (x-t)/2 - 60

Solve the equation-7(x-2)= -84
Answer:
x = 14
Step-by-step explanation:
First, use the distributive property:
-7x + 14 = -84
-7x = -98
x = 14
Answer:
my answer got deleted for no reason so ill add it again with my way of solving it with steps this time.
x=14
Step-by-step explanation:
divide both sides by -7
[tex]\frac{-7(x-2)}{-7} =\frac{-84}{-7}[/tex]
simplify
[tex]x-2=12[/tex]
add two to both sides
[tex]x-2=12[/tex]
[tex]+2[/tex] [tex]+2[/tex]
simplify
[tex]x=14[/tex]

Add a restaurant the ratio of kids meals sold two adult meals sold was 5:4 if there were 20 kids meals sold what is the combined amount of kids and adult meals sold?
Answer: The combined amount of kids and adult meals sold = 36
Step-by-step explanation:
Let the number of kids meals sold = 5x and the number of adult meals = 4x
Since total kids meals sold = 20
Then, 5x= 20
⇒ x =4
Adult meals = 4(4) = 16
Combined meals sold = kids meals + Adult meals
= 20+ 16
= 36
Hence, the combined amount of kids and adult meals sold = 36
A store is selling T-shirts. Which is the best deal?
8 for $26
5 for $30
4 for $15
12 for $39
10 for $45
divide cost by quantity. The lowest rate is the best buy:
26/8 = 3.25 each
30/5 = 6.00 each
15/4 = 3.75 each
39/12 = 3.25 each
45/10 = 4.50 each
The 8 for 26 and the 12 for 39 are both the same price each and are the better buys.
You spend 264 dollars on clothes. Shirts cost 24 and pants cost :2 you buy a total of 9 items
EQUATIONS:
24x + 32y = 264
x + y = 9
x is shirts, y is pants
SOLVING by substitution:
x = 9 - y
24(9 - y) + 32y = 264
216 - 24y + 32y = 264
8y = 48
y = 6
x + 6 = 9
x = 3
