The light from a lamp casts a shadow of a man standing 10 feet away from
the lamppost. The shadow is 5 feet long. The angle of elevation from the tip
of the shadow to the lamp is 50°. To the nearest foot, the lamppost is _________
feet tall.
Answer: x ≈ 18 ft
Step-by-step explanation:
We will use our trig knowledge to solve this.
The man is standing 10 ft away, but we also need to add the 5 ft shadow as well as that is a point on our triangle.
We can set up a simple trig equation of: tan(50) = x/15
x being the height of the lamppost.
Now we solve.
tan(50) = 1.1918
1.1918 *15 = x
x = 17.876
Now round to the nearest foot.
x ≈ 18 ft

can someone please help me answer this
Answer:
Step-by-step explanation:
5) Perimeter = 15 + 21 + 15 + 21 = 72 cm
6) diameter = 12 cm
Radius r = 12/2 = 6 cm
Circumference = 2πr
= 2 * 3.14 * 6
= 37.68 cm
8) Distance around the track = 2 *circumference of semi circle + 80 + 80
= circumference of circle + 80 + 80
= 2 * 3.14 * 10 + 80 +80
= 62.8 +80 +80
= 222.8 cm
A large box P containing 15 cans of biscuits weighs 23 kg and weighs 500g when empty. A box containing 8 cans of the same biscuits Q weighs 12.3kg. Box Q What is the mass when the box is empty?
Answer:
300 g
Step-by-step explanation:
weight of a can of biscuits= (23- 0.5)/15= 1.5 kg
weight of 8 cans= 1.5 * 8= 12 kg
mass of the empty box Q= 12.3- 12= 0.3 kg= 300 g
Answer:
300 g or 0.3 kg
Step-by-step explanation:
23 kg - 500g = 22.5 kg
each can of biscuits weighs 22.5 ÷ 15 = 1.5 kg
if the box Q weighs 12.3kg when there's 8 box of biscuits then
8 × 1.5 = 12 kg is the weight of biscuits and the remaining 300 g is box Q's weight

Rubi tosses a quarter off the Main Street bridge into the St. John’s River. The distance, in feet, the quarter is above the water is modeled by the equation d(t) = −16t2+96t + 112, where t represents time in seconds.
Answer: a. 112 feet, b= 3 seconds, c= 256 feet, d = 6 seconds
Step-by-step explanation:
Here is the complete question:
Rubi tosses a quarter off the Main Street bridge into the St. John’s River. The distance, in feet, the quarter is above the water is modeled by the equation d(t) = −16t2+96t + 112, where t represents time in seconds.
Find the actual value(s) now to each question. Use the solution from the previous question to assist you with what you are actual solving for.
(a) From what height was the quarter tossed?
The quarter was tossed at 112 feet.
(b) How long does it take the quarter to reach its maximum height?
It will take ________ seconds for the quarter to reach its maximum height.
(c) What is the maximum height of the quarter?
The maximum height of the quarter is ________ feet.
(d) How much time does it take for the quarter to hit the water?
It will take ______ seconds for the quarter to hit the water.
a. Since the function is
d(t) = −16t² + 96t + 112,
The coin is tossed at 112 feet. This is because it is the the initial value of the function. It is the constant term and does not depend on any other variable.
b. To calculate the maximum height, we have to find vertex of the function, that has coordinates of h,k and,
h = -b/2a and k = f(h).
From the question, we are aware that,
a = -16, b = 96, c = 112
Using the values, the vertex will be:
h = -b/2a
= -96/(2 × -16)
= -96/-32
= 3
k = f(3)
= 16t² + 96t + 112
= -16(3)² + 96(3) + 112
= -144 + 288 + 112
= 256
The maximum height is therefore 256 feet, and time needed to reach the height will be 3 seconds.
c. The maximum height has been calculated and it is 256 feet.
d. The time it take for the quarter to hit the water will be:
= 3 seconds × 2 = 6 seconds
Since the maximum height took 3 seconds, it would take another 3 seconds to hit the water. This makes it 6 seconds

Which is the equation of the line of best-fit for this scatterplot? (2nd picture)
Answer:
D) y = (81/2)x - (160,069/2)
Step-by-step Explanation:
From the scatter plot in the graph attached below, we are given the ordered pairs of the coordinates (2009, 1330), (2013, 1492), we can derive the equation of the line of best-fit for the scatter plot using the slope-intercept formula.
Thus, the slope-intercept formula is y = mx + b, where m is the slope of the line; and b is the y-intercept.
We need to find m, and then b to input into the formula to get our equation of the line.
==> Finding m using the two sets of coordinate given on the graph [ (2009, 1330) and (2013, 1492) ]:
slope (m) = (y2 - y1)/(x2 - x1)
m = (1492 - 1330)/(2013 - 2009)
= 162/4
m = 81/2
Next is to find b, which is the y-intercept
Recall, y = mx + b
Using one of the coordinates given (2009, 1330), we can find b by inputting 1330 for y, 2009 for x, and 81/2 for m in the slope-intercept formula:
Thus, we would have ==>
1330 = (81/2 * 2009) + b
1330 = (162,729/2) + b
1330 - 162,729/2 = b
(2,660 - 162,729)/2 = b
- 160,069/2 = b
Having known the values of m, and b, let's input their values to get the equation of the line.
Thus, using the slope-intercept formula y = mx + b, the equation of the line of best-fit for the scatter plot would be
==> y = (81/2)x +(-160,069/2)
y = (81/2)x - (160,069/2)

Correct question is:
A cone with radius 3 units is shown below. Its volume is 57 cubic units. Find the height of the cone. Use 3.14 for pi and round your final answer to the nearest hundredth.
Hi, to answer this question we have to apply the next formula:
Volume of a cone = 1/3 x π x radius^2 x height
Replacing with the values given:
57 = 1/3x 3.14 x (3)^2 (h)
Solving for h
57 = 1/3 x 3.14 x 9 (h)
57 =9.42h
57/9.42 =h
h= 6.05 units

find the measure of angle B. Show work please
Answer:
c. 54.6°
Step-by-step explanation:
The Law of Cosines can be used to find the first of the unknown angles in a triangle with only three side lengths given.
b² = a² +c² -2ac·cos(B)
Solving for B, we have ...
2ac·cos(B) = a² +c² -b²
B = arccos((a² +c² -b²)/(2ac)) = arccos((10.4² +21.9² -18²)/(2(10.4)(21.9)))
B = arccos(0.579053) ≈ 54.6° . . . . . matches choice C
Answer:
C 54.6°
Step-by-step explanation:
Using cosine law:
18² = 10.4² + 21.9² - 2(10.4)(21.9)cosB
cosB = 2029/3504
B =54.6160711

If the function m(x) has the point (1, 9) on its graph name a point that would be on the function 17n(x) + 2.
Answer: if we want to find a point of 17*m(x) + 2, one is (1, 155)
Step-by-step explanation:
I guess you want to know a point in the function
h(x) = 17*m(x) + 2
we know that m(1) = 9 (because m(x) has the point (1, 9) in it's graph)
then h(1) = 17*m(1) + 2 = 17*9 + 2 = 155
so this function has the point (1, 155)

When a number is decreased by 25%, the result is 22. What is the original number to the nearest tenth?
The decrease is 25% so this means that 22 is 75% of the original number (100% - 25% = 75%)
Divide 22 by 75%:
22/ 0.75 = 29.3
The answer is 29.3

What are the coordinates of the point on the directed line segment from (3, 3) to (7,−5) that partitions the segment into a ratio of 5 to 3
Answer:
The coordinates of the point is (5.5, -2)
Step-by-step explanation:
Okay, what we want to do here is to get the point that divides the line that joins the points (3,3) to (7,-5) in the ratio 5 to 3
Generally, given the ratio a:b and we want to divide the line joining the points (x1,y1) and (x2,y2) in that ratio, we use the condensed formula below;
Let’s call the point dividing the line in the given ratio z.
The coordinates of Z is;
{(bx1 + ax2)/(a+b), (by1 + ay2)/(a+b)}
In this question (x1,y1) = (3,3)
While (x2,y2) = (7,-5)
while a:b = 5:3
Substituting these values into the coordinate equation for point z, we have ;
{((3(3) + 5(7))/(5+3), ((3)(3) + 5(-5))/(5+3)}
= {44/8 , -16/8} = {5.5, -2}
Help me find these angles ASAP
Answer:
49°
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
let x be the other exterior angle then sum and equate to 360
37 + 84 + 49 + 38 + 35 + 68 + x = 360
311 + x = 360 ( subtract 311 from both sides )
x = 49
The other exterior angle = 49°
