Answer:
None of these can be triangles.
Step-by-step explanation:
All triangles’ side lengths must follow this pattern - the two shortest sides must be GREATER than the longest when added together. 6 + 4 < 10, so this isn’t a triangle. 3 + 8 = 11, so this isn’t a triangle. 8.4 + 7.7 < 16.6, so this isn’t a triangle. Lastly, 4 + 3 < 16, so this isn’t a triangle. Hope this is accurate & helpful! Best of luck.

Triangle E F G. Side E F is 6 meters, F G is 5 meters, E G is 7 meters. Angle F is 87 degrees and angle G is 58 degrees. Triangle K L J. Side K L is 28 meters, L J is 24 meters, J K is 20 meters. Angle K is 58 degrees, L is 35 degrees, J is 87 degrees. What can you conclude about these triangles? Check all that apply. Angle E corresponds to angle L. All corresponding angles are proportional. The measure of angle E is 29°. The two triangles are similar. The two triangles are congruent.
Answers
Answer:
Angle E corresponds to angle L
The two triangles are similar
Step-by-step explanation:
The information given has been sketched in a diagram attached below.
✔️In ∆EFG:
EF = 6 m
FG = 5 m
EG = 7 m
<F = 87°
<G = 58°
<E = 180 - (87° + 58°) (sum of triangles)
<E = 35°
✔️In ∆KLJ:
KL = 28 m
LJ = 24 m
JK = 20 m
<K = 58°
<L = 35°
<J = 87°
✔️Let's compare both triangles:
<K = <G = 87° (corresponding angles)
Therefore, length of the sides opposite each angle corresponds to each other, which is:
LJ corresponds to EF, hence:
LJ/EF = 24/6 = 4 (corresponding sides are proportional)
<J = <F = 87° (corresponding angles)
KL corresponds to EG, hence:
KL/EF = 28/7 = 4 (both sides are proportional)
<L = <E = 35° (corresponding angles are equal)
JK corresponds to FG, hence:
JK/FG = 20/5 = 4 (both sides are proportional).
As we can see from the above, all three angles of both triangles are congruent/equal to each other. This means they have the same shape.
Also, all three corresponding sides of both triangles are proportional. This means they have different sizes.
Therefore, we can conclude that both triangles are similar to each other because they have corresponding angles that are equal, while their corresponding sides are proportional.
The following statements therefore apply:
Angle E corresponds to angle L
The two triangles are similar
Answer:
Angle E corresponds to angle L
The two triangles are similar

Answer:
Step-by-step explanation:
The larger the number of throws the closer the results will be to the probability of a head. That is for a fair coin it should be close to 50%.
With only 10 throws you could get a result not close to 50% but the coin could still be fair.
So Simon's results ( 100 throws) would be more useful to decide if the coin is biased or not.
A soup recipe uses noodles, cheese, and potatoes in the extended ratio 4:5:7. How many cups of cheese are needed to make 192 cups of soup?
Answers
Answer: 60 cups of cheese
Step-by-step explanation:
noodles:cheese:potatoes
4:5:7
192 total cups of soup
each unit of recipe is 4+5+7=16
so divide total cups of soup by one recipe unit
192/16=12
This means 12 recipe units were used. So each value from ratio 12 times...
4:5:7 = one unit of soup (16 cups)
48:60:84 = 12 units of soup (192 cups)
So 60 cups of cheese are needed for 192 cups of soup.

The area of a square is equal to side times side, so a+b=one of the sides of a square so you multiply this by another a+b to get the whole square
Same as the last part but c is equal to one side so we do c*c for the are
The area of a triangle is 1/2*base*height, so we do 1/2*a*b since a is equal to the base of the triangle and b is equal to the height. This is only equal to 1 triangle so we multiply this by 4 since there are 4 triangles in total

Given

Required
Find [tex]\tan(A - \frac{\pi}{4})[/tex]
In trigonometry:
[tex]\tan(A - B) = \frac{\tan A - \tan B}{1 + \tan A \tan B}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - \tan \frac{\pi}{4}}{1 + \tan A \tan \frac{\pi}{4}}[/tex]
[tex]tan \frac{\pi}{4} = 1[/tex]
So:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A * 1}[/tex]
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A}[/tex]
This gives:

6^3 is not a perfect square because 6 x 6 x 6 (216) is cubed not square

6^5 is not a perfect square because 6 x 6 x 6 x 6 x 6 (7776) it isn't an equal factor combination, that when multiplied together, produce the number 7,776. That means 7,776 is not a perfect square.
6^2 is a perfect square because 6x6= 36 and 36 is a perfect square.

Find the values of a and b given that the polynomial P(x) = x^3+ ax^2 +x+b, is divisible by
both x-1 and x + 3.
Answers
Answer:
a=4
b=-6
Step-by-step explanation:
If P(x) is divisible by x-c, then P(c)=0.
So P(1)=0 implies 1^3+a1^2+1+b=0
and
P(-3)=0 implies (-3)^2+a(-3)^2+-3+b=0
So notice we have a system to solve.
Let's simply it.
First equation:
1^3+a1^2+1+b=0
1+a+1+b=0
2+a+b=0
a+b=-2
Second equation:
(-3)^3+a(-3)^2+-3+b=0
-27+9a-3+b=0
9a+b-30=0
9a+b=30
Let's put our system together:
a+b=-2
9a+b=30
This is setup so if we subtract the equations b will eliminate allowing us to solve for a:
-8a=-32
a=4
If a=4 and a+b=-2, then 4+b=-2 giving us b=-6.
a=4
b=-6

Answers
10x-y=8(x+y)
how can we show that the numbers digits are reversed using our variables? the numbers digits being reversed means that the digit that was in the tens place is now in the ones place and vise versa. so the reversed digit number would look like this: 10y+x
(10x+y)-45=10y+x
now you can solve the system of equations.
10x+y=8(x+y)
solve for one variable, i’ll choose x
2x=7y
x=7/2y, or 3.5y
(10x+y) - 45= 10y+x
go to your second equation
(10•3.5y+y)-45=10y+3.5y
plug in for x
36y-45=45
y=2
x=3.5y go back to the equation where you solved for c in terms of y
x=3.5(2)
plug in for y
x=7
the number is 72
let’s check

Answer:q = - 9 and r = - 10
Step-by-step explanation:
since g(x) is divided by (x - 1) with remainder - 12, then (1) = 4(1)³ + q(1)² + r + 3 = - 12, that is 4 + q + r + 3 = - 12
q + r + 7 = - 12 ( subtract 7 from both sides )
q + r = - 19 → (1)
Since (x - 3) is a factor of g(x), then
g(3) = 4(3)³ + q(3)² + 3r + 3 = 0, that is
108 + 9q + 3r + 3 = 0
9q + 3r + 111 = 0 ( subtract 111 from both sides )
9q + 3r = - 111 → (2)
The 2 equations to be solved simultaneously are (1) and (2)
Multiply (1) by - 3
- 3q - 3r = 57 → (3)
Add (2) and (3) term by term to eliminate r
6q = - 54 ( divide both sides by 6 )
q = - 9
Substitute q = - 9 into (1)
- 9 + r = - 19 ( add 9 to both sides )
r = - 10
