Answers
Answer:
Step-by-step explanation:
First, draw the diagram.
We have the variable, l.
Then, we have:
tan angle=opposite/adjacent
So plug it in, it will be:
tan 60=l/50m
So then l=tan60*50m.
tan60=1.732
l=1.732*50m
and so out answer ends up being 86.6m.

If the length of qr is 8 cm and the length of qs is 12 cm, what is the length of rs?
Answers
Answer:
8.94
Step-by-step explanation:
Given that
qs = 12cm
qr = 8cm
Required
rs
Using the pythagoras theorem
Let us assume qs is the hypotenuse side
qs² = qr² + rs²
12² = 8² + rs²
144 = 64 +rs²
rs² = 144 - 64
rs² = 80
rs = √80
rs = 8.94
Hence the value of rs is 8.94

Which of the following is the equation of a line in slope-intercept form for a
line with slope = 1 and yintercept at (0, -1)?
A. y= 4x+1
B. y= 1x-1
C. y=-x-1
D. y= 4x-1
Answers
Hi there!
[tex]\large\boxed{\text{ B. } y = 1x - 1}[/tex]
Recall that the equation of a line is:
y = mx + b, where:
m = slope
b = y-value of the y-intercept.
We are given that the slope is 1 and the y-intercept is -1, so:
m = 1
b = -1
The correct equation is B. y = 1x - 1
Find the expected value of the winnings
from a game that has the following
payout probability distribution:
Payout ($)| 0 4 6 8 10
Probability 0.45 0.3 0.1 0.1 0.05
Expected Value = [?]
Round to the nearest hundredth.
Answers
Answer:
2.65
Step-by-step explanation:
Multiply each payout by its probability, then add those products.
See the attached image.
The first column has the payouts. The second column has the probabilities. The third column has the results of multiplying a payout by its probability.
The sum of the entries in the third column is 2.65
The expected value is $3.1 if the payout probability distribution is payout ($)| 0 4 6 8 10 probability 0.45 0.3 0.1 0.1 0.05
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
From the table we can find the expected value:
Multiply payout to probability such that:
= 0×0.45 = 0
= 4×0.3 = 1.2
And so on
Now sum all values(refer to the attached table)
= 0+1.2+0.6+0.8+0.5
= $3.1
Thus, the expected value is $3.1 if the payout probability distribution is payout ($)| 0 4 6 8 10 probability 0.45 0.3 0.1 0.1 0.05

Perimetrul unui teren de sport este de 224m. Alfa lungimea si latimea terenului, daca latimea este cu 8m mai mare decat 1/3 din lungime
Answers
Answer:
I. L = 78 metros
II. W = 34 metros.
Step-by-step explanation:
Deje que la longitud del rectángulo sea L. Deje que el ancho del rectángulo sea W.Sabemos que un campo deportivo tiene forma rectangular.
Dados los siguientes datos;
Perímetro del rectángulo = 224 m
Traduciendo el problema verbal a una expresión algebraica, tenemos;
W = ⅓L + 8 = L/3 + 8
Matemáticamente, el perímetro de un rectángulo viene dado por la fórmula;
P = 2 (largo + ancho)
Sustituyendo en la ecuación, tenemos;
224 = 2(L + [L/3 + 8])
224 = 2L + 2L/3 + 16
Reordenando la ecuación (recolectando términos semejantes), tenemos;
224 - 16 = 2L + 2L/3
224 - 16 = 8L/3
208 = 8L/3
Multiplicación cruzada, tenemos;
8L = 208 * 3
8L = 624
L = 624/8
L = 78 metros
Para encontrar el ancho;
W = L/3 + 8
W = 78/3 + 8
W = 26 + 8
W = 34 metros.

[tex]\frac{3}{38}[/tex]
Step-by-step explanation:
[tex]\frac{6}{20}\cdot \frac{5}{19}=\frac{30}{380}=\boxed{\frac{3}{38}}[/tex]
Answer:
3/38
Step-by-step explanation:
So, you add the total numbers of socks and the total is 20. Since there is 6 white socks the first time you pick, your first fraction is 6/20 (3/10). So since you didn't put the first sock back, now the probability of picking another white sock is 5/19. So now multiply your fractions, and your answer should be 15/190 (Simplifyed 3/38)

How many triangles can be drawn with one 90o angle, a 70° angle, and an included side measuring 3 inches? Explain. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
Answers
Answer:
2
Step-by-step explanation:
This is because any of the sides can be the one measuring 3 inches. Since it is a triangle, the sum of angles is 180. Let the third angle be x.
So, x + 90° + 70° = 180°
x + 160° = 180°
x = 180° - 160°
x = 20°
So, the third angle is 20°.
If the included side is a side other than the hypotenuse side, we can find it by applying the sine rule.
The included side can be either side other than the hypotenuse.
Also, either of the third angle in each triangle can be 20°
So, we have two sides and two triangles.
If the included side is the hypotenuse side, we use Pythagoras' theorem to find the length of the other two sides (and they must be equal)since the angle between the two sides is a right-angle, that is, 90°.
Since the other two angles are not equal, we cannot have a triangle with two equal sides and an hypotenuse. That is, we cannot have an isosceles triangle. So, no third triangle.
So, the total number of triangles that can be drawn with one 90° angle, a 70° angle and an included side measuring 3 inches is 2.

Answers
Answer:
6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 8^2 = 10^2
a^2 +64=100
a^2 = 100-64
a^2 = 36
Take the square root of each side
sqrt(a^2) = sqrt(36)
a = 6

In the morning, the temperature was – 10°C. By the afternoon, it had risen to – 2°C. What was the change in temperature from the morning to the afternoon?
Answers
Answer:
8 °C
Step-by-step explanation:
Step 1: Given data
Initial temperature value (T1): -10 °C
Final temperature value (T2): -2 °C
Step 2: Calculate the change in temperature from the morning to the afternoon
To calculate the change in the temperature, we have to perform the subtraction T2 - T1.
ΔT = T2 - T1 = (-2 °C) - (-10 °C) = -2 °C + 10 °C = 8 °C
The temperature change is positive, meaning that the temperature increased.
