Weight Lifting A weight lifter puts an
X-pound weight on each side of a bar.
A weight 5 pounds heavier than the first is
then added to both sides. Finally, a weight
5 pounds heavier than the second weight
is added to both sides. The expression
2[x + (x + 5) + (x + 2(5))]models the
total weight lifted. Simplify the expression.
What would the expression be if each added
weight was 10 pounds heavier than the
previous weight?
Answer:
Expression: 6x + 30
Step-by-step explanation:
2[x + (x + 5) + (x + 2(5))]
2[2x + 5 + x + 10]

6x + 30

Answer:
3/5
Step-by-step explanation:
the sin of an acute angle in a right triangle is the ratio of the opposite side to the hypotenuse
24/40=3/5
Answer:
sine of Z = 36.87 (36.86989765 to be exact)
Step-by-step explanation:
Remember SOH-CAH-TOA
Sine=OH=opposite/hypotenuse.
You want to find the angle of Z so, theta Z= 24/40 (O/H)
On your calculator, put inverse sine(sin ^-1) of 24/40.
So, sin-1 (24/40)=36.87 degrees.

Lous Rate of change is 218 words per minute
and Ricardo can read 150 words per minute
meaning Louis can read faster than Ricardo
Step-by-step explanation:
Answer:
A - 218 B-150 C-Louis
Step-by-step explanation:
for A - 436 /2 = 218 which means one equals 218
for B - 300/2 = 150 and 900/6 = 150

3x = 4x - 12 हे समीकरण सामान्य रूपात लिहा
Answer:
x=12
Step-by-step explanation:
Here,
3x =4x - 12
12= 4x - 3x
12= x
Using algebra tiles, show a model of 4x + 2.
Answer:
Your Correct answer for this question is the first option.
Step-by-step explanation:
The Four 1 tiles on the first half of 4x+2 represent the 4, and the x represents the variable! Then the question is separated by a plus sign and Two more 1 tiles, which represent 4x+2
Steps to solve:Step 1:
Add all the tiles from the first sector of the question before the +.
(1+1+1+1+x) = 4x
Step 2:
Add the second sector together.
(1+1) = 2
Step 3:
Combine all sectors together.
(4x) + (2) = 4x +2

The regular price of a video game is $59.,95. This week it is on sale for 15% off. What does the game cost this week (before taxes)
Answer: $50.96
Step-by-step explanation:
The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.
The game cost this week before taxes will be:
= 59.95 - (15% × 59.95)
= 59.95 - (0.15 × 59.95)
= 59.95 - 8.9925
= $50.9575
= $50.96
The amount this week is $50.96

Un avion vuela ciudad a hacia la ciudad b, a una distancia de 150 millas, y despues vira con un angulo de 50° y se dirige hacia la ciudad C, a una distancia de 100 milllas,¿Con que angulo debe virar el piloto en la ciudad C para regresar a la ciudad A?
Answer:
El piloto debe virar a 87.7° en la ciudad C para regresar a la ciudad A.
Step-by-step explanation:
Podemos encontrar el angulo que debe virar el piloto en la ciudad C para regresar a la ciudad A usando el Teorema del coseno:
[tex] (AC)^{2} = (AB)^{2} + (BC)^{2} - 2(AB)(BC)cos(50) [/tex]
[tex] (AC)^{2} = (150 mi)^{2} + (100 mi)^{2} - 2(150 mi)(100 mi)cos(50) [/tex]
[tex] (AC) = 115 mi [/tex]
Ahora podemos encontrar el ángulo entre los puntos C y A (AC) usando la ley de los senos:
[tex] \frac{sin(50)}{AC} = \frac{sin(\alpha)}{AB} [/tex]
[tex] \frac{sin(50)}{115 mi} = \frac{sin(\alpha)}{150 mi} [/tex]
[tex] \alpha = 87.7 [/tex]
Por lo tanto, el piloto debe virar a 87.7° en la ciudad C para regresar a la ciudad A.
Espero que te sea de utilidad!
El piloto debe virar con un ángulo de 61° 42' 12'' para regresar a la ciudad A.
Dado que un avión vuela desde la ciudad A hacia la ciudad B, a una distancia de 150 millas, y después vira con un ángulo de 50° y se dirige hacia la ciudad C, a una distancia de 100 millas, para determinar con que ángulo debe virar el piloto en la ciudad C para regresar a la ciudad A se debe realizar el siguiente cálculo, aplicando las teorías del seno y el coseno:
Lado A = 150Lado B = 100Lado C = ???Angulo B = 50√(150² + 100² - 2 x 150 x 100 x cos 50) = Lado C√(22500 + 10000 - 19283.62) = Lado C√13216.3717094 = Lado C114.96 = Lado CSen C/114.96 = Sen 50/100Sen C = (114.96 x Sen 50) /100Sen C = 0.8806C = 61,72100 = 6072 = X72 x 60 / 100 = X42,2 = X100 = 60 20 = X20 x 60 / 100 = X12 = X61° 42' 12'' = Ángulo CPor lo tanto, el piloto debe virar con un ángulo de 61° 42' 12'' para regresar a la ciudad A.

From the observation deck of a lighthouse 70 meters above sea level, the lighthouse keeper can see a fishing boat at a 25 degree angle of depression.What is the horizontal distance, to the nearest meter, from thebase of the lighthouse to the fishing boat?
Answer:
150.12
Step-by-step explanation:
From the observation deck of a lighthouse 70 meters above sea level, the lighthouse keeper can see a fishing boat at a 25 degree angle of depression.What is the horizontal distance, to the nearest meter, from the base of the lighthouse to the fishing boat?
We solve the above question using the Trigonometric function of tan
tan y = Opposite /Adjacent
y = 25°
Opposite = 70m
Adjacent = x = Horizontal distance
Therefore:
tan 25 = 70m/x
tan 25 × x = 70m
x = 70m/tan 25
x = 150.11548444m
Approximately = 150.12m
The horizontal distance, to the nearest meter, from the base of the lighthouse to the fishing boat is 150.12m
Find the missing angle.
Round to the nearest tenth.
Answer:
9) 18.2
10) 59 degrees
11) 48.6 degrees
12) 25.8 degrees
13) 41.1 degrees
Step-by-step explanation:
number 9:
sine 60 = [tex]\frac{21}{x}[/tex]
x = 18.18 ⇒ 18.2
number 10:
tan x = [tex]\frac{30}{18}[/tex]
x = 59
number 11:
sine x = [tex]\frac{12}{16}[/tex]
x = 48.59 ⇒ 48.6
number 12:
cos x = [tex]\frac{36}{40}[/tex]
x = 25.8
number 13:
sine x = [tex]\frac{25}{38}[/tex]
x = 41.1
