Answer:

The answer to your question is: One has saved $35 and the other $20

Step-by-step explanation:

Data

2 brothers

combined savings = $55

One brother has $15 more than the other

x = savings of one brother

y = savings of the other brother

   - Process

Write an equation or two equations and solve it for x and y

(1)       x + y = 55

(2)      x = y + 15               Solve this system by substitution (2) in (1)

       y + 15 + y = 55

       2y = 55 - 15

       2y = 40

         y = 40/2

         y = $ 20

      x = 20 + 15

     x = $ 35

Geoffrey is evaluating the expression (-3)^6(2^6)/(-3)^5(2^2) as shown below.
Alekssandra [29.7K]

Answer:

48.

Step-by-step explanation:

First you multiply the number by itself as many times as the number of the exponent is. In this case you <u>multiply -3 to itself 6 times which makes -729</u>, <u>2 to the 6th power is 64</u>, <u>-3 to the 5th power is -243, and 2 to the 2nd power is 4.</u> Then you <u>multiply -729 by 64 which makes -46656</u> and <u>multiply -243 by 4 which makes -972</u>, and then <u>divide -972 from -46656</u> <em>which makes 48</em>.

A right triangle has one angle that measures 6 degrees. What is the measure of the other acute angle?
mylen [45]

84

Step-by-step explanation:

All three angles add up to 180 degrees.

Since it is a right triangle, there is a 90 degrees angle. And we know another angle is 6 degree. So we use the formula: 180 - (known angle + known angle) = unknown angle

Plugging in the information we get: 180 - (90 + 6) = x

180 - 96 = 84

So x = 84

We can check our work by adding all known angles to see if it is equal to 180 using the formula known angle + known angle + known angle = 180 degrees

Plugging in the information we get: 90 + 6 + 84 = 180

96 + 84 = 180

180 = 180

So the answer 84 is correct

If the arc length of a sector in the unit circle is 4.2, what is the measure of the angle of the sector?
Dennis_Churaev [7]
The unit circle is a circle with radius r=1, so you have

L=r\theta\implies4.2=\theta

where \theta is measured in radians, so \theta\approx241^\circ.

Solve: sin2x cosx + cos 2x sin x = √3/2
ludmilkaskok [199]
We are given with the expression or equation s<span>in2x cosx + cos 2x sin x = √3/2. The expression can be patterned from the trigonometric identity sin (a + b) = sin a cos B + cos A sin B. In this case, the expression is equal to sin 3x = sqrt 3 /2. using arc sign, x is equal to pi/9 </span>
