If you decide to study 4 hours more a week during your junior year (32 weeks) with the expectation of getting $2,000 scholarship

aliina [53]

Answer: You will get $2,000 for 128 hour, or 2,000/128 = $15.625 per hour study time.

Step-by-step explanation:

We will give the solution of the following problem:

"If you decided to study for four hours a week during your junior year (32 weeks) with the expectation of getting a $2,000 scholarship to college, how much is your study time worth per hour?"

In 32 weeks you will have total of 4*32 = 128 study hours.

You will get $2,000 for 128 hour, or 2,000/128 = $15.625 per hour study time.

2 (10- 22x0) = (2x + 2)

Lorico [155]

Answer:

x=9

Step-by-step explanation:

2(10-22×0)=(2x+2)

Applying BODMAS

2(10-0)=(2x+2)

2(10)=2x+2

2x+2=20

2x=20-2

2x=18

x=9

To find the distance across the river, the given diagram is laid out. what is the distance rounded to the nearest meter?

kati45 [8]

Given:

Angle A = 18.6°

Angle B = 93°

Length of side AB = 646 meters

To find:

the distance across the river, distance between BC

Steps:

Since we know the measure of 2 angles of a triangle we can find the measure of the third angle.

18.6° + 93° + ∠C = 180°

111.6° + ∠C = 180°

∠C = 180° - 111.6°

∠C = 68.4°

Therefore the measure of angle C is 68.4°.

now we can use the law of Sines,

$\frac{BC}{sinA}=\frac{AB}{SinC}$

$\frac{BC}{sin(18.6)}= \frac{646}{sin(68.4)}$

$BC[sin(68.4)] = 646 [sin(18.6)]$

$BC = \frac{646*sin(18.6)}{sin(68.4)}$

$BC = \frac{646 * 0.3190}{0.9298}$

$BC = 221.63$

$BC = 222$ meters

Therefore, the distance across the river is 222 meters.
