Step-by-step explanation:

Step 1: Our output value is 350.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$350=100\%$.

Step 4: Similarly, $x=25\%$.

Step 5: This results in a pair of simple equations:

$350=100\%(1)$.

$x=25\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{350}{x}=\frac{100\%}{25\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{350}=\frac{25}{100}$

$\⇒x=87.5$

Therefore, $25\%$ of $350$ is $87.5$

Answer:

The answer is 35 and here is why!

Step-by-step explanation:

It is because, m = 10

So, therefore 3.5m = 3.5*m = 3.5 * 10

Therefore, answer is 35.

Answer:

AA ≅ AA postulate

Step-by-step explanation:

Given

[tex]A=(1,2)[/tex]

[tex]B = (3,5)[/tex]

[tex]C = (4,3)[/tex]

[tex]k = 3[/tex] --- scale factor

Required

Determine which statement that justifies the similarities between ABC and A'B'C'

When ABC is dilated by a scale factor of 3 to form A'B'C', the sides A'B'C are 3 times as large as the sides of ABC.

However, all three angles of both triangles remain the same. This is so, because dilation do not affect angles.

So, a statement that can be used to justify the similarities is:  AA ≅ AA

Red: 2.035 x 10(4)

Step-by-step explanation:

Answer:

Red.

Step-by-step explanation:

Scientific notation consists of the ones place with a decimal right after it and a 10 to the something power next to it, therefore red is your answer.

Answer:

we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and

PM = QM

Step-by-step explanation:

because it's a parrallelogram, Ad = BC and AB = DC.

P passes through both  AB and DC on a diagonal, angles created by P have oppoiste exterior angles of eachother.

the diagonals of AC create congruent angles at DMC and AMB and because P is cutting through them, the angles P cuts at DMQ and QMC are equal to that of AMP and PMB

that being said, we now see that the angles of APM triangle and AMC triangol are equal and because the diagonal of BD is is being cut by AC, which AD is parralel to BC  and AB to Dc, we know now that lines AM and MC are congruent

we thus have enough informnation to prove that the two triangles are congruent. Because of thism, one side of the triangles, Pm which is the congruent side to that of PQ must be equal as well and

thus PM = QM

The alternate interior angles formed by the parallel sides and a common

transversal are equal, such that ΔPBM and ΔQDM are congruent.

Answer:

We conclude that:

[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]

Step-by-step explanation:

Given the radical expression

[tex]\sqrt{\left(-81\right)x^2}[/tex]

simplifying the expression

[tex]\sqrt{\left(-81\right)x^2}[/tex]

Remove parentheses:  (-a) = -a

[tex]\sqrt{\left(-81\right)x^2}=\sqrt{-81x^2}[/tex]

Apply radical rule:   [tex]\sqrt{-a}=\sqrt{-1}\sqrt{a},\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

                 [tex]=\sqrt{-1}\sqrt{81x^2}[/tex]

Apply imaginary number rule:  [tex]\sqrt{-1}=i[/tex]

                 [tex]=i\sqrt{81x^2}[/tex]

Apply radical rule:   [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]

                  [tex]=\sqrt{81}i\sqrt{x^2}[/tex]

                  [tex]=9i\sqrt{x^2}[/tex]

Apply radical rule:  [tex]\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0[/tex]

                  [tex]=9ix[/tex]

Therefore, we conclude that:

[tex]\sqrt{\left(-81\right)x^2}=9ix[/tex]
