Answer:

43 1/3 minutes to iron 10 shirts

Step-by-step explanation:

Number of shirts : Time taken

3 shirts : 13 minutes

10 shirts : x minutes

3 / 13 = 10 / x

Cross product

3 * x = 13 * 10

3x = 130

Divide both sides by 3

3x / 3 = 130 / 3

x = 43 1/3 minutes

x = 43 minutes 20 seconds

It will take 43 minutes 20 seconds to iron 10 shirts

14a - (2a +9)=2/3 (12a-18)​
Dmitrij [34]

Answer: a=-0.75

Step-by-step explanation:

14a - (2a +9)=2/3 (12a-18)​

14a - 2a -9=2/3 * 6(2a-3)​

12a-9=2*6/3 (2a-3)​

12a-9=2*2(2a-3)​

12a-9=4(2a-3)​

12a-9=8a-12

4a-9=-12

4a=-3

a=-3/4

a=-0.75

Give triangle TRY, find TY. Round your answer to the nearest hundredth.
3241004551 [841]

The length of TY is 2.26.

Solution:

In ΔTRY, θ = 37°, Adjacent side = 3.

To find the length of TY.

Using trigonometry identity,

$\tan\theta=\frac{{opposite}}{{Adjacent}}

$\tan37^\circ=\frac{{TY}}{3}

$3\tan37^\circ=TY

$3\times 0.75355=TY

$TY=2.26065

TY = 2.26

Hence the length of TY is 2.26.

A log is floating on swiftly moving water. A stone is dropped from rest from a 50.8-m-high bridge and lands on the log as it pas
TiliK225 [7]

Answer:

Horizontal distance between the log and the bridge when the stone is released = 17.24 m

Step-by-step explanation:

Height of bridge, h = 50.8 m

Speed of log = 5.36 m/s

We need to find the horizontal distance between the log and the bridge when the stone is released, for that first we need to find time taken by the stone to reach on top of log,

We have equation of motion. s = ut + 0.5 at²

       Initial velocity, u = 0 m/s

       Acceleration, a = 9.81 m/s²

       Displacement, s = 50.8 m

Substituting,

                  s = ut + 0.5 at²

                 50.8 = 0.5 x 9.81 x t²

                     t = 3.22 seconds,

So log travels 3.22 seconds at a speed of 5.36 m/s after the release of stone,

We have equation of motion. s = ut + 0.5 at²

       Initial velocity, u = 5.36 m/s

       Acceleration, a = 0 m/s²

       Time, t = 3.22 s

Substituting,

                  s = ut + 0.5 at²

                 s = 5.36 x 3.22 + 0.5 x 0 x 3.22²

                    s = 17.24 m

Horizontal distance between the log and the bridge when the stone is released = 17.24 m
