well I hate to say this but my question was there are 13 animals and 40 legs how many pigs and chickens are there and you said 9
Licemer1 [7]

Answer:

There are 7 Pigs and 6 Chickens

Step-by-step explanation:

Let's assume

Pigs= x

Chicken=y

(eq 1) x+y = 13----------y=13-x

4x + 2y = 40

replace the y

4x+ 2(13-x) = 40

you get x = 7

replace x in y=13 -x

you get y = 6

hence the answer.

Based on the information given say whether or not △ABC∼△FED. Explain your reasoning.
GalinKa [24]

Answer:

Yes, △ABC ∼ △FED by AA postulate.

Step-by-step explanation:

Given:

Two triangles ABC and FED.

m∠A = m∠B

m∠C = m∠A + 30°

m∠E = m∠F = x

m∠D = 2x-20°.

Now, let m∠A = m∠B = y

So, m∠C = m∠A + 30° = y+30

Now, sum of all interior angles of a triangle is 180°. Therefore,

m∠A + m∠B +  m∠C = 180

y+y+y+30=180\\3y=180-30\\3y=150\\y=\frac{150}{3}=50

Therefore, m∠A = 50°, m∠B = 50° and m∠C =  m∠A + 30° = 50 + 30 = 80°.

Now, consider triangle FED,

m∠D+ m∠E + m∠F = 180

2x-20+x+x=180\\4x=180+20\\4x=200\\x=\frac{200}{4}=50

Therefore,  m∠F = 50°  

m∠E = 50° and  

m∠D =  2x-20=2(50)-20=100-20=80\°

So, both the triangles have congruent corresponding angle measures.

m∠A = m∠F = 50°

m∠B = m∠E = 50°

m∠C = m∠D = 80°

Therefore, the two triangles are similar by AA postulate.

for the polynomial P(x)=4x^2-5x+6 and c =1, find p(c) by (a. direct substitution and (b. the remainder theorem
nata0808 [166]
p(x)=4x^2-5x+6

c=1\implies p(c)=4(1)^2-5(1)+6=5

By the remainder theorem, the remainder upon dividing a polynomial p(x) by a linear binomial x-c is equal to p(c). Via synthetic division, we get

1   |  4   -5   6
.    |        4  -1
- - - - - - - - - - -
.    |  4   -1   5

which translates to

\dfrac{4x^2-5x+6}{x-1}=4x-1+\dfrac5{x-1}

or

4x^2-5x+6=(4x-1)(x-1)+5

Indeed, when x=1, the first term on the right hand side vanished and we're left with 5.

∠EFG and ∠GFH are a linear​ pair, m∠EFG=3n+23​, and m∠GFH=2n+32. What are m∠EFG and m∠​GFH?
NARA [144]

the measures of the angles are:

  • m∠EFG = 98°
  • m∠GFH = 82°
<h3>How to find the measures of the angles?</h3>

Two angles are a linear pair if their measures add up to 180°.

Then we will have that:

∠EFG + ∠GFH = 180

Here we know that:

m∠EFG=3n+23

m∠GFH=2n+32

Replacing that we get:

3n + 23 + 2n + 32 = 180

5n + 55 = 180

5n = 180 - 55 = 125

n = 125/5 = 25

Then the measures of the angles are:

m∠EFG=3n+23 = 3*25 +23 = 98°

m∠GFH=2n+32 = 2*25 + 32 = 82°
