Answer:

12.5 feet

Step-by-step explanation:

how to:

lets find the angle that corresponds with the 10 foot side.

to do that we add 50 degrees plus 90 degrees (right angle) to get 140 degrees.

as we know, a triangles angles will total 180 degrees, so 180 - 140 = 40 degrees for the angle corresponding to the 10 foot side.

put these into ratios:

Angle A = Angle B

side a side b

now plug in our numbers:

50 degrees = 40 degrees

X 10 feet

Cross multiply:

50 (10 feet) = 40 (x)

solve for x:

500 = 40 (x)

500/40 = x

12.5 = x

Subtract w + 4 from 6w + 3

Simora [160]

It is well simples, look:

Answer = (6w + 3) - ( w + 4 )

A = 6w + 3 - w - 4

A = 6w - w + 3 - 4

A = 5w - 1

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

2x - 3y = 25

5x + 3y = 10

Step 2: Solve for x

Elimination

Combine two equations: 7x = 35
[Division Property of Equality] Divide 7 on both sides: x = 5

Step 3: Solve for y

Substitute in x [1st Equation]: 2(5) - 3y = 25
Multiply: 10 - 3y = 25
[Subtraction Property of Equality] Subtract 10 on both sides: -3y = 15
[Division Property of Equality] Divide -3 on both sides: y = -5

Helen rented a kayak at the lake. There is a charge of $8 as an initial fee and then $2 an hour for every hour that she uses the

vladimir1956 [14]

$20 total cost
$8 fee
$2 per hour

20 (total) - 8 (initial fee) = 12 (amount spent on hourly use)
12 (amount spent on hourly use) / 2 (cost per hour) = 6 (hours)

20 - 8 = 12
12 / 2 = 6

ANSWER: 6 hours

Solve the equation for y. 2x + 5y = 5 y=x +1 y= -10% + 25 y=22+1 y=x +5

Elena-2011 [213]

Answer:

y=-2/5x+1

y=x+1

y=249/10

y=23

y=x+5

Step-by-step explanation:

Let's solve for x.

y=x+5

Step 1: Flip the equation.

x+5=y

Step 2: Add -5 to both sides.

x+5+−5=y+−5

x=y−5

Answer:

x=y−5

What is the volume of the figure below if a = 4.5 units, b = 5.8 units, and c = 3 units?

Anastasy [175]

Answer:

The answer to your question is the letter C

Step-by-step explanation:

Data

a = 4.5 u

b = 5.8 u

c = 3 u

Process

1.- Calculate the volume of the rectangular prisms

Formula

Volume = a x a x c

Substitution

Volume = 4.5 x 4.5 x 3

Result

Volume = 60.75 u³

But there are two rectangular prism

Total volume = 2 x 60.75

= 121.5 u³

2.- Calculate the volume of the triangles

Formula

Volume = base x width x height

Substitution

Volume = 5.8 x 3 x 4.5

Result

Volume = 78.3 u³

3.- Total volume

Volume = 121.5 + 78.3

= 199.8 u³
