Answer 1

Answer:

b)30 boys c)1425 beats

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

b and g are the number of boys and girls, respectively.

b:g = 3:4

b = 3x, g = 4x

3x+4x = 70

x = 10

There are 30 boys.

:::::

(380 beats)/(4 minutes) = (380/4 beats)/minute = (95 beats)/minute

15 minutes × (95 beats)/minute = 1425 beats

your question is wrong.......

Now use the expression found in Part C for the distance between your eyes and the object at point O, and find the ratio of the apparent distance to the real distance, d/D. Remember that the apparent distance is the distance calculated by your eyes using the angle θa instead of the angle θw. Since we are dealing with small angles, you may use the approximation sin(x)≈x and asin(x)≈x.

Answer:

Hello your question is incomplete attached below is the missing part of the  question

answer :  ( d / D )  =  [tex]n_{a}[/tex]

                                 [tex]n_{w}[/tex]

Step-by-step explanation:

Given data:

Apparent distance = distance calculated using angle ∅a

also applying the approximation ; sin(x) ≈ x  and  asin(x) ≈ x

Find the ratio of apparent distance to real distance (d / D )

Using the given data in the question the ratio of apparent distance to real distance ( d / D )  =  [tex]n_{a}[/tex]

                                 [tex]n_{w}[/tex]

where [tex]n_{a}[/tex] = index of refraction ( air )

           [tex]n_{w}[/tex] = index of refraction ( water )

can someone help me on this one ... this is pythagorean theorem and converse geometry

Answers

Answer:

The correct answer is D.

Step-by-step explanation:

According to the Pythagorean Theorem, the legs of a right triangle squared and added together is equivalent to the hypotenuse squared. To solve for x, you can use any of the two right triangles. Each of the bottom legs of the right triangles is 9 units since the two right triangles are congruent, so now we apply the Pythagorean Theorem to solve for x. [tex]x^2+9^2=19^2[/tex] ⇒ [tex]x^2+81 = 361[/tex] ⇒ [tex]x^2 = 280[/tex] ⇒ [tex]x = \sqrt{280}[/tex] ⇒ [tex]x = \sqrt{4 * 70}[/tex] ⇒ [tex]x = \sqrt{4} * \sqrt{70}[/tex] ⇒ [tex]x = 2\sqrt{70}[/tex].

Point P is the centroid of △LMN. Find PN and QP. QN=42

Answers

The diagram of the triangle is missing, so i have attached it.

Answer:

PN = 28

QP = 14

Step-by-step explanation:

We are told that QN = 42

Since P is the centroid, by inspection we can see that;

PN = ⅔QN

Thus, PN = ⅔ × 42

PN = 28

Also, we see that PN + QP = QN

Thus;

28 + QP = 42

QP = 42 - 28

QP = 14

Following are the calculation on the PN and QP:

Mp, Lp, and NQ are indeed the central lines of a large briangle MNL, according the problem. Particles entersect at point P.This is referred to as a baryc enter of a friangle.And has the quality Np= 2PQ, therefore we can obtain it.

              [tex]Np = \frac{2}{3} QN\\\\ PQ = \frac{1}{3} QN \\\\NP=\frac{2}{3} \times 42= 28 \\\\PQ= \frac{1}{3} \times 42 = 14 \\\\[/tex]  

When you are aware, the point p is indeed the barycenter of a large triangle, and this is an important trait.

Answer:

[tex] y = \frac {1}{2}x +2[/tex]

Step-by-step explanation:

Line is passing through the points (0, 2) & (2, 3)

Slope of line = (3 - 2)/(2 - 0) = 1/2

Equation of line in point slope form is given as:

y - 2 = 1/2(x - 0)

2(y - 2) = x

2y - 4 = x

2y = x + 4

[tex] y = \frac {1}{2}x +\frac {4}{2}[/tex]

A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second. The polynomial 16t^ ^ 2+220t+8 gives the height in feet that the skyrocket will rise in t seconds. How high will the rocket rise if it has a 7-second fuse?

The equation above is - 16t ^ 2 + 220t + 8

A) 748
B) 764
C) 788
D) 882

Answers

Given :

A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second.

The polynomial -16t² + 220t + 8 gives the height in feet that the skyrocket will rise in t seconds.

To Find :

How high will the rocket rise if it has a 7-second fuse?

Solution :

Since, it is given that the rocket has a fuse time of 7 seconds.

Putting value of 7 sec in given equation, we get :

Height = -16×( 7 )² + 220×( 7 ) + 8

Height = 764 m

Therefore, height of rocket in 7 second fuse is 764 m.

Write an equation in slope-intercept form of the line that passes through the given points. 0,4 4,2

Answers

First, find the slope: m = Δy/Δx = (2-4)/(4-0) = -0.5

The "intercept" in the slope-intercept form of a line is the y-intercept. And at the y-intercept, x = 0. Conveniently, one of our points has an x = 0, i.e., the point (0,4). So, our equation would be y = -0.5x + 4.

If you wanted to double-check, you could use the point (4,2) to find the point-slope equation of the line and see if it matches up with the slope-intercept form above. Given a slope of -0.5 and a point (4,2), our point-slope equation would be y - 2 = -0.5(x - 4). If we expand this, we get y - 2 = -0.5x + 2. Solving for y, we obtain y = -0.5x + 4.

Thus, y = -0.5x + 4 would be our equation.

E.C. What is the standard equation of a circle with center (h,k) and radius r in the coordinate plane?

Answers

Answer:

(x-h)^2 + (y-k)^2 = r^2

Step-by-step explanation:

Here, we want to write the standard equation of the circle

We have this as;

(x-h)^2 + (y-k)^2 = r^2

The above equation is the standard equation for the circle

Answer:

(x − 4)2 + (y + 6)2 = 25

(x − 4)2 + (y − (-6))2 = 52

When I compare my equation with the standard form, (x − h)2 + (y − k)2 = r2, I get h = 4, k = -6, and r = 5. The center is at (4, -6), and the length of the radius is 5.
