Answer: He studied for 315 minutes. Because he studied for 1hr and 45 mins (105 mins). Then you multiply this by 3 because it's been three days.

Hope this helps!

Answer:

y = 25.20 m

Step-by-step explanation:

By applying tangent rule in ΔABC,

tan(25)° = \frac{\text{Opposite side}}{\text{Adjacent side}}

             = \frac{y}{BC}

BC = \frac{y}{\text{tan}(25)} --------(1)

Now we apply tangent rule in ΔABD,

tan(15)° = \frac{y}{BC+CD}

tan(15)° = \frac{y}{BC+40}

BC + 40 = \frac{y}{\text{tan}(15)}

BC = \frac{y}{\text{tan}(15)} - 40 -------(2)

From equation (1) and (2),

\frac{y}{\text{tan}(25)}=\frac{y}{\text{tan}(25)}-40

\frac{y}{\text{tan}(25)}-\frac{y}{\text{tan}(25)}=-40

y[\frac{1}{\text{tan}(25)}-\frac{1}{\text{tan}(25)}]=-40

y(2.1445 - 3.7321) = -40

1.5876y = 40

y = 25.1953

y ≈ 25.20 m

Therefore, measure of y is 25.20 m.

Help for 1-4 and remember show work
Vanyuwa [196]
1. C) $30.00
If you find how much each Pound is worth, which is $2.50 you multiply that by 12 which is $30.00.
2. < because -3.4 is father from 0 on a number line and -2.1 is closest to 0 on the number line so -2.1 is greater than -3.4. | -3.4 < -2.1
3. C) 1/4 because you need to be able to turn the fraction into a decimal and you need to multiply 4 and 1 by 5 and that is 5/20 then you multiply 5 and 20 by 5 and that gives you 25/100 and now you can turn it into a decimal which is 0.25 and 0.27 is greater than 0.25.
4. A) I because if point S is at (-2, 10) it would be in quadrant II so if point T is a reflection of point S than point T is in the I quadrant because the y-axis is the vertical line going up and down. So you put point T across the y-axis which is
at (2, 10) in quadrant I.

Juliette [100K]

Answer:

0.83 mi/min

Step-by-step explanation:

Start with 80 km/hr.  Convert this to the units miles/hr:

(80 km/hr)(1 mile/1.6 km) = 50 miles/hr

Next, apply the equality 60 min / 1 hr = 1 to 50 miles/hr:

50 miles.      1 hr

------------- * ------------ = 5/6 mi/min, or 0.83 mi/min

     hr          60 min

Mekhanik [1.2K]
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30

additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0

so x+3-3=10-3
x+0=7
x=7
