Answer:

Option D. $0.7963540136$

Step-by-step explanation:

step 1

Convert $52\°\ 47'$ to degrees

$52\°\ 47'=52\°+47/60)=52.7833\°$

step 2

Using a calculator

Find the value of $sin(52.7833\°)$

$sin(52.7833\°)=0.7963540136$

Help plzz (30) points for both of the question-plz help - this is life or dead answer

Elodia [21]

Answer:

The answer is B) 11.

Step-by-step explanation:

We can solve this by making an expression to represent the situation. Let x = the number of student books in the box (what we're looking for):

$2.3x + 4.3 + 0.4 = 30$

$2.3x + 4.7 = 30$

$2.3x + 4.7 - 4.7 = 30 - 4.7$

$2.3x = 25.3$

$2.3x/2.3 = 25.3/2.3$

$x = 11$

Lanette drove 248 miles in 4 hours. At the rate, how many hours will it take her to drive a additional 93miles.

LenaWriter [7]

Answer:

1.5 hours

Step-by-step explanation:

using the relationship between distance/ speed / time

distance = speed × time

speed = $\frac{distance}{time}$ = $\frac{248}{4}$ = 62 mph

travelling at this rate then

time = $\frac{distance}{speed}$ = $\frac{93}{62}$ = 1.5 hours

Please help with this problem <br> thanks so much

Lunna [17]

Answer:

5/17

Step-by-step explanation:

If we do the multiplication first, we get:

$\frac{4-(12\div-12)}{13+(-8\div-2)}$

If we do the division next, we get:

$\frac{4+1}{13+4} = 5/17$

If DEF=GJH, find each missing measure

Bas_tet [7]

Congruent triangles have equal corresponding sides and angles.

The measure of the side lengths are: $\mathbf{DF = 16m}$ , $\mathbf{JH = 14m}$ and $\mathbf{GJ = 19m}$
The measure of the angles are: $\mathbf{\angle G = 34^o}$ , $\mathbf{\angle J = 41^o}$ and $\mathbf{\angle F = 105^o}$

The given parameters are:

$\mathbf{\triangle D EF \cong \triangle GJH}$

$\mathbf{EF = 14m}$

$\mathbf{D E = 19m}$

$\mathbf{GH = 16m}$

$\mathbf{\angle D = 34^o}$

$\mathbf{\angle H = 105^o}$

$\mathbf{\triangle D EF \cong \triangle GJH}$ means that triangles DEF and GHJ are congruent triangles.

So, we have:

$\mathbf{DF = GH}$

This gives

$\mathbf{DF = 16m}$

Also, we have:

$\mathbf{JH = EF}$

This gives

$\mathbf{JH = 14m}$

Also, we have:

$\mathbf{GJ = DE}$

This gives

$\mathbf{GJ = 19m}$

The following angles are also congruent

$\mathbf{\angle F = \angle H}$

This gives

$\mathbf{\angle F = 105^o}$

Also, we have:

$\mathbf{\angle G = \angle D}$

This gives

$\mathbf{\angle G = 34^o}$

The measure of angle J is then calculated using

$\mathbf{\angle J + \angle H + \angle G = 180^o}$

This gives

$\mathbf{\angle J + 105 + 34= 180^o}$

$\mathbf{\angle J + 139= 180^o}$

Subtract 139 from both sides

$\mathbf{\angle J = 41^o}$
