Answer:
1.55 feet.
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle R = 24°
Hypothenus = RS = 3.8 feet
Opposite = ST = x
The value of x can be obtained by using the sine ratio. This is illustrated below:
Sine R = Opposite / Hypothenus
Sine 24 = x / 3.8
Cross multiply
x = 3.8 × Sine 24
x = 3.8 × 0.4067
x = 1.55 feet
Thus, the Lenght ST is 1.55 feet.
Answer:
2/3
Step-by-step explanation:
since they are just two colors of fish inside, since the probability is always 1.. so we have to minus 1/3 from 1,which is 1-1/3=2/3
X=Lucy´s money
y=Edy´s money
we can suggest this system of equations:
x=y+(35/100)y ⇒x=135y/100
x+y=206.8
solve by substitution method.
(135y/100)+y=206.8
Least common multiple=100
135y+100y=20680
235y=20680
y=20680/235=88
then:
x=135y/100=135(88)/100=118.8
Answer:
Lucy´s money=$118.8
Edy´s money=$88
To check:
Together, the girls have saved a total of $118.8+$88=$206.8
Lucy´s savings account has: $88+(35/100)$88=$118.8, 35% more monty than Edy´s. account. .
The simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.

What is an expression?</h3>
- An expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.
To find the simplified expression:
Given -
- Distance cycled = x² + 7 miles
- Distance ran = 2x miles
- Distance swam = x - 2 miles
Thus,
- Total distance she covers = x² + 7 + 2x + x - 2
- Total distance = x² + 3x + 5 miles
Therefore, the simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.

The complete question is given below:
Joy is training for a triathlon. She runs a distance of 2x miles, cycles a distance of (x2 + 7) miles, and swims a distance of (x - 2) miles. Which simplified expression is equivalent to the total distance, in miles, Joy covers?
(A) x2 + 3x + 5
(B) x2 + 3x + 9
(C) 3x2 + 5
(D) 3x2 + 9
<span>The first part is already in squared terms. "19.25 sq ft"
Taking the measurements for the mirror 3ft and 5ft, you'd get: "15 sq ft."
Subtract that answer from the previous number to get "4.25 sq ft.
Hope this helps out a little lol :)</span>
