Show the work for 2 divided by 50

Answers

Answer 1

Answer: first you would do this write out 50 divided by 2 as an equation and put how many times does 2 go into 5 and 2 goes into 5 two times so you put two over the 5 on top of the division house and do that number multiplied by the number your dividing by which is 2 and hat equals 4 so do 5 minus 4 and that equals 1 bring the zero thats beside the 50 down and make the number 1 a 10 and see how many times 2 goes into 10 and that is 5 so you put the five on top of the division house then do five times 2 and that equals 10 down and do 10 minus 10 which equals 00 and then your done your answer should be 25

Answer:

m∠TYW = 93°

Step-by-step explanation:

When naming anangle, the three letters used in the name represent specific points or vertices that define the angle. Each letter has a distinct meaning:

First Letter (Initial Point): This represents the starting point for one of the rays or line segments that form the angle.
Second Letter (Vertex): This represents the point where the two rays or line segments that form the angle meet.
Third Letter (Terminal Point): This represents the terminal point, which is the endpoint for the other ray or line segment that forms the angle.

Therefore, the angle named "VYU" refers to an angle that starts at point V, has a vertex at point Y, and ends at point U. This is shown on the attached diagram in red. Given m∠VYU = 93°:

m∠VYU = m∠6 = 93°

The angle named "TYW" refers to an angle that starts at point T, has a vertex at point Y, and ends at point W. This is shown on the attached diagram in blue.

m∠TYW = m∠4

Assuming that lines TU and VW are straight lines, ∠6 and ∠4 are vertically opposite angles.

According to the Vertical Angles Theorem, when two straight lines intersect, the opposite vertical angles are congruent.

Therefore, ∠4 ≅ ∠6, so:

m∠TYW = m∠VYU

As m∠VYU = 93°, then m∠TYW = 93°.

Answer:

VYW and TYW are opposite interior angles and thus have the same value of 93 deg.

A weight is attached to to a spring that is fixed to the floor. The equation h=7cos (pi/3 t) models the height, h, in centimeters after t seconds of the weight being stretched and released.

Answers

Answer:

$t=(3)/(\pi)\left(\cos ^(-1)(h)/(7)\right)$

Step-by-step explanation:

The given function is,

$h=7\cos \left((\pi)/(3)t\right)$

$\Rightarrow \cos \left((\pi)/(3)t\right)=(h)/(7)$

$\Rightarrow (\pi)/(3)t=\cos ^(-1)(h)/(7)$

$\Rightarrow t=(3)/(\pi)\left(\cos ^(-1)(h)/(7)\right)$

This is the solution of t.

Now we have to find t when h is 1 cm, 3 cm and 5 cm.

When h=1

$t=(3)/(\pi)\left(\cos ^(-1)(1)/(7)\right)=78.10\ s$

When h=3

$t=(3)/(\pi)\left(\cos ^(-1)(3)/(7)\right)=61.71\ s$

When h=5

$t=(3)/(\pi)\left(\cos ^(-1)(5)/(7)\right)=42.41\ s$

lets solve for t in the height equation:

h = 7 cos (pi/3 t)
cos (pi/3 t) = h/7
pi/3 t = cos^-1 (h/7)

t = (3/pi) cos^-1 (h/7)

then we substitute:

t = (3/pi) cos^-1 (1/7)
t = 78.1 s

t = (3/pi) cos^-1 (3/7)
t= 61.71

t = (3/pi) cos^-1 (5/7)
t = 42.41

those are the times in seconds respectively.

Mallory has three dollars in her wallet if this is 10% of her monthly allowance what is her monthly allowance

Answers

Answer:

$30.

Step-by-step explanation:

Definition:

Allowance: A regular sum of money that is given by a parent or guardian to a child in each month.

Solution:

We can use the following formula to find the total amount of Mallory's monthly allowance:

$\sf \textsf{ Percentage of allowance saved} * \textsf{ Total allowance = Amount saved}$

In this case, we know that Mallory has saved $3, which is 10% of her monthly allowance.

Plugging these values into the formula, we get:

$\sf 10\% * \textsf{ Amount saved} = 3$

$\sf 0.10 * \textsf{ Amount saved} = 3$

Divide both sides by 0.10.

$\sf \textsf{ Amount saved} = (3)/(0.10)$

$\sf \textsf{ Amount saved} = 30$

Therefore, Mallory's monthly allowance is $30.

Answers

the measure of ABD=180°- 54°=26°
and then the measure of ADB= x
and x + 26° + 28°= 180°, sum of anlgle in a triagle property
it means x= 180°- 26-28=126°
application of sinus law in the triangle

sin 28 / BD = sin 126/ AD = sin 26/ 25 so we can deduce that

AD= 25sin126 / sin26= 46.12
let 's consider the triangle ADC, so for finding h, we have sin 28 = h / AD
and then h = AD x sin28=21.65

Calculate the height of the tower is 21.65
