Meredith has $630,000 she wants to save. If the FDIC insurance limit per
Viefleur [7K]

Answer:

$200,000 in bank A, $200,000 in bank B, $230,000 in bank C

Step-by-step explanation:

Meredith has $630,000

Limit per depositor, per bank, is $250,000

She needs to distribute her money between three Banks to guarantee that her money is insured.

A. $200,000 in bank A, $200,000 in bank B, $230,000 in bank C

It can be seen in A that her deposit per bank deposit didn't exceed the $250,000 limit in the three Banks.

B. $200,000 in bank A, $170,000 in bank B, $260,000 in bank C

Here, her deposit in bank C exceeds $250,000, so there is no guarantee for insurance in bank C

C. $160,000 in bank A, $180,000 in bank B, $290,000 in bank C

Her deposit in bank C is $290,000 which exceeds the $250,000 limit. Therefore, no guarantee for insurance of her money in bank C

D. $160,000 in bank A, $200,000 in bank B, $270,000 in bank C

you

Also, her deposit in bank C exceeds $250,000, so there is no guarantee for insurance in bank C

The way her money can be distributed between three Banks and guarantee insurance is

A. $200,000 in bank A, $200,000 in bank B, $230,000 in bank C.

That way, her deposit per bank is less than the $250,000 limit

What value of cc​ will complete the square below and make the expression a perfect square trinomial?
Sav [38]

Question: What value of c​ will complete the square below (x^{2} +30x+c) and make the expression a perfect square trinomial?

Answer: c = 225

Step-by-step explanation:

Perfect square trinomials come in the form a² + 2ab + b², which is equal to (a + b)². In the presented trinomial, we can immediately identify that <u>a = x, and b² = c</u>, but we need to find the numerical value of c.

To do this, note that the middle term, or <u>2ab, corresponds with (is equal to) 30x</u>. We know that a = x, and thus, <u>2ab = 2bx</u>. Now, 2bx and 30x are corresponding terms; thus, <u>2bx = 30x</u>.

Dividing by 2x on both sides gives us <u>b = 15</u>. Therefore, c = b² = 15² = 225. (As a squared binomial, this would be (x + 15)² as a = x and b = 15.)

Proofs and congruent triangles ( serious full answers only or 1 star and report )
krok68 [10]

Answer:

<em>There are 5 ways to find if two triangles are congruent.</em>

<em>SSS-</em><em> {Side Side Side Congruence.}</em>

<em>This law of congruence states that if we have two triangles, each with the same measures on each 3 sides it deems the triangles congruent.</em>

<em>SAS- </em><em>{Side Angle Side Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with 2 equal sides and one angle which is common among them; the triangles are congruent.</em>

<em>ASA- </em><em>{Angle Side Angle Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with 2 congruent angle measures and 1 congruent side; the triangles are indeed congruent.</em>

<em>AAS- </em><em>{Angle Angle Side Congruence.}</em>

<em>You may be wondering how this law of congruence differs from the previous one. </em><em> ASA </em><em>refers to any two angles and the included side, whereas </em><em>AAS </em><em>refers to the two corresponding angles and the non-included side.</em>

<em>HL- </em><em>{Hypotenuse Leg Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with a common (congruent) leg and hypotenuse; the triangles are congruent.</em>
