John’s bank account increased in value from last year to those year by 8% to $250. If the account increases by the same percenta

inessss [21]

Answer:

$270

Step-by-step explanation:

We are given;

The rate of increase is 8%
The new amount is $250

We need to determine the value in the next year with the same rate of increase;

Therefore;

250% = 100%

New amount = 100 + 8 = 108%

Therefore;

New amount = (250 × 108)÷ 100

= $270

Therefore, the value in the next year is $270

Given mZ1= x° and m Z2 = (x +50)".

Tju [1.3M]

Given:

m∠1= x° and m∠2 = (x +50)°.

To find:

The value of x, m∠1 and m∠2.

Solution:

From the figure it is clear that, transversal side intersect the opposite sides which are parallel and form ∠1 and ∠2.

Sum of same sided interior angles is 180 degrees. So,

$m\angle 1+m\angle 2=180^\circ$

$x^\circ+(x+50)^\circ=180^\circ$

$2x^\circ+50^\circ=180^\circ$

$2x^\circ=180^\circ-50^\circ$

$2x^\circ=130^\circ$

Divide both sides by 2.

$x^\circ=65^\circ$

$x=65$

Now,

$m\angle 1=65^\circ$

$m\angle 2=(65+50)^\circ=115^\circ$

Therefore, the correct option is C.

Find the missing lengths in the triangle. round to the nearest tenth if necessary

lubasha [3.4K]

Answer:

$x=8,\\y\approx 6.9$

Step-by-step explanation:

The side lengths of all 30-60-90 triangles are in ratio $x:x\sqrt{3}:2x}$ , where $2x$ is the hypotenuse of the triangle and $x$ is the side opposite to the 30 degree angle.

In the given diagram, the side labelled 4 is opposite to the 30 degree angle. Since $x$ is labelled as the hypotenuse of the triangle, $x$ must be $4\cdot 2=\boxed{8}$ .

Variable $y$ must then represent $x\sqrt{3}$ for $x=4$ , yielding $y=4\sqrt{3}\approx \boxed{6.9}$
