Answer:

25(s)

s= the number of hours

Step-by-step explanation:

25(s)

answer would be 25(3) = 75 miles.

75+25= 100 miles

so the distance from Jose's house to City A is 100 miles

Answer:D(t) = 100 - 25t

Step-by-step explanation:

Distance travelled = speed × time

Jose plans to drive at

a speed of 25 miles per hour and he drove for three hours. It means the the distance that Jose covered in three hours would be

25 × 3 = 75 miles

After driving for 3 hours, he will be 25 miles away from City A.

This means that the total distance from city A is 75 + 25 = 100 miles

Let D(t), represent Jose's distance

from city A, t hours after leaving his house. Therefore,

D(t) = 100 - 25t

A statue is mounted on top of a 21 foot hill. From the base of the hill to where you are standing is 57feet and the statue subte

AleksandrR [38]

Please find the attached diagram for a better understanding of the question.

As we can see from the diagram,

RQ = 21 feet = height of the hill

PQ = 57 feet = Distance between you and the base of the hill

SR= h=height of the statue

$\angle SPR$ =Angle subtended by the statue to where you are standing.

$\angle x=\angle RPQ$ = which is unknown.

Let us begin solving now. The first step is to find the angle $\angle x$ which can be found by using the following trigonometric ratio in $\Delta PQR$ :

$tan(x)=\frac{RQ}{PQ} =\frac{21}{57}$

Which gives $\angle x$ to be:

$\angle x=tan^{-1}(\frac{21}{57})\approx20.22^{0}$

Now, we know that $\angle x$ and $\angle SPR$ can be added to give us the complete angle $\angle SPQ$ in the right triangle $\Delta SPQ$ .

We can again use the tan trigonometric ratio in $\Delta SPQ$ to solve for the height of the statue, h.

This can be done as:

$tan(\angle SPQ)=\frac{SQ}{PQ}$

$tan(7.1^0+20.22^0)=\frac{SR+RQ}{PQ}$

$tan(27.32^0)=\frac{h+21}{57}$

$\therefore h+21=57tan(27.32^0)$

$h\approx8.45 ft$

Thus, the height of the statue is approximately, 8.45 feet.

13. Find the value of x. 140° 136° х 148° 142° 150°

garik1379 [7]

Answer:

sum of interior angle of heptagon is 900°.

140°+148°+136°+150°+142°+90°+x=900°

806+x=900°

x=900°-806°

x=94°
