The kite is 73.4 feet above the ground.
A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.
Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.
Let h represent the perpendicular distance from the top of the kite to her hand. The angle of elevation = 34°. Hence:
sin(34) = h/125
h = 69.9 feet
The distance from the kite to the ground = 69.9 + 3.5 = 73.4 feet

A 45 gram sample of a substance that's used to sterilize surgical equipment has a
K-value of 0.1483.
Find the substance's half-life, in days. Round your answer to the nearest tenth.
Answer:
Answers
Answer:
t = 4.7 days
Step-by-step explanation:
The half life formula is
N = No * e ^ (-kt)
Where No is the initial amount of the substance
N = 45 e ^ (-.1483 t)
We want 1/2 of the substance left
22.5 is half of 45 grams
22.5 = 45 e ^ (-.1483 t)
Divide each side by 45
1/2 = e ^ (-.1483 t)
Take the natural log of each side
ln(1/2) = ln (e ^ (-.1483 t))
ln(1/2) = -.1483t
Divide each side by -.1483
ln(1/2) / -.1483 = t
t=4.67395
Rounding to the nearest tenth
t = 4.7 days

a bag contains 517.6 g of dollar coins. Each coin has a mass of 8.1 g
Answers
Answer:
63 coins
Step-by-step explanation:
I am going to assume you are asking how many dollar coins are in the bag, I apologize if I am wrong.
So first, set up the problem. The total number is 517.6 and each coin weighs 8.1
So you would divide 517.6 by 8.1 to get 63.9012346 (which has too many decimal points so round)
But rounding up would get the wrong number because it would be too light for the amount of coins said to be in there, but rounding down gives you 63.
So 63 times 8.1 is 510.3 and the total could consider the weight of the bag into the total 517.6.
A section of a rectangle is shaded.
The area of the shaded section is 63 square units.

x = 8
Step-by-step explanation:
To get x, we will use the pythagoras theorem;
10² = x² + (12/2)²
100 = x² + 6²
100 = x² + 36
100 - 36 = x²
64 = x²
Swap
x² = 64
x =√64
x = 8
Hence the value of x is 8

∠SPR = 48°
Step-by-step explanation:
The relevant relations are ...
an inscribed angle is half the measure of the arc it interceptsa triangle inscribed in a semicircle is a right trianglean exterior angle is equal to the sum of the remote interior angles of a triangleSince PR is a diameter, triangle PQR is a right triangle with angle PQR being the right angle.
This makes ∠PRQ complementary to ∠RPQ:
∠PRQ = 90° -28° = 62°
Exterior angle RTS is the sum of interior angles TRQ and TQR, so angle TQR can be found to be ...
110° = 62° +∠TQR
∠TQR = 110° -62° = 48° = ∠SQR
__
Angle TQR, also angle SQR, subtends arc SR, so is the same measure as angle SPR, which also subtends the same arc.
∠SPR = 48°

Jorge y Noelia van a jugar al "4 en línea". Si el tiempo de una partida es de 2 minutos y 30 segundos, ¿cuántas partidas podrían jugar durante 25 minutos?
Answers
Answer:
Pueden jugar 10 partidas en 25 minutos.
Step-by-step explanation:
Sabemos que el tiempo de una partida es:
t = 2min + 30 seg
Queremos saber cuantas partidas se pueden jugar en un total de 25 minutos.
Esto es simplemente igual a la cantidad de veces que podemos "meter" 2 minutos y 30 segundos en 25 minutos, que está dado por el cociente:
N = (25 min)/(2min + 30 seg)
Pero para resolver esto, primero tenemos que tener todos nuestros valores en las mismas unidades.
Sabiendo que 60 se = 1 min
entonces:
30 seg = (30/60) min = 0.5 min
Entonces podemos reescribir:
t = 2 min + 30 seg = 2 min + 0.5 min = 2.5 min
Ahora podemos resolver el cociente:
N = (25 min)/(2.5 min) = 10
Esto significa que pueden jugar 10 partidas en 25 minutos.

Step-by-step explanation:
The formula to find the area of a trapezoid is the following,
[tex]A=(h)(\frac{(b_1)+(b_2)}{2})[/tex]
Where ([tex]h[/tex]) represents the heights of the trapezoid, ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.
One is given all of these values in the picture,
[tex]h = 2.5\\\\b_1 = 2\\\\b_2 = 4[/tex]
Substitute these values into the formula and solve for the area of the trapezoid,
[tex]A=(2.5)(\frac{(2)+(4)}{2})[/tex]
Simplify,
[tex]=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5[/tex]
Given that √5=2.24 and √7.07, find the value of
(a) √0.05
(b)√0.0005
(c)√0.5
(d)√0.005
Answers
Answer:
0.05 = 5/100
sqrt(0.05] = sqrt(5/100) = sqrt(5)/sqrt(100) = 2.24/10 = 0.224
0.0005 = 5/10000
sqrt [0.0005) = sqrt(5/10000) = sqrt(5)/sqrt(10000) =
= 2.24/100 = 0.0224
0.5 = 50/100
sqrt(0.5) = sqrt(50/100) = sqrt(50)/sqrt(100) = 7.07/10 =
= 0.707
0.005 = 50/10000
sqrt(0.005) = sqrt(50/10000) = sqrt(50)/sqrt(10000) =
