musickatia [10]

Answer:

w = 16

Step-by-step explanation:

p = w x l

I = 5w

w = ?

96 = w x l

96 = w x (5w)

96 = 6w

16 = w

Please help. Solve the value of x

lutik1710 [3]

Answer:

x = 6

Step-by-step explanation:

GIVEN :-

An isosceles triangle with one side extended.
Measure of one base angle = 66°
Measure of another base angle = m∠2 = 11x°

TO FIND :-

Value of x

FACTS TO KNOW BEFORE SOLVING :-

An isosceles triangle has 2 equal sides (known as legs) & the third side (known as base).
The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.
In an isosceles triangle , base angles are equal in measure.

PROCEDURE :-

As it's an isosceles triangle , it's base angles are equal .

So, m∠2 = 66°

⇒ $11x = 66$

⇒ $x = \frac{66}{11} = 6$

The graph shows a proportional relationship between the number of workers and weekly cost in dollars for a company. Use the poin

galben [10]

The weekly cost per worker is: $800

Unit rate can be used for calculating expenses, calculating cost of multiple units, or calculating expenses.

Recall:

Unit rate is calculated using: $\mathbf{\frac{y_2 - y_1}{x_2 - x_1} }$

Unit rate represents the amount of a quantity compared to its unit of measure.

Unit rate can be used for calculating expenses, calculating cost of multiple units, or calculating expenses.

Since the relationship between number of workers and weekly cost is proportional, we would apply $\mathbf{\frac{y_2 - y_1}{x_2 - x_1} }$ in determining the weekly cost per worker using the points, (6, 4800) and (15, 12000):

Substitute

Unit rate/weekly cost per worker = $\frac{12,000 - 4,800}{15 - 6} = \frac{7,200}{9} = 800$

Unit rate/weekly cost per worker = $800

In summary, the weekly cost per worker is: $800

Unit rate can be used for calculating expenses, calculating cost of multiple units, or calculating expenses.

Choose the system of equations which matches the following graph:

Karo-lina-s [1.5K]

Blue:

y-intercept: (0, 4)

a slope: m = -1/2

The equation: y = -1/2x + 4 |·2

2y = -x + 8 |+x

x + 2y = 8

Red:

y-intercept: (0, 3)

the slope: m = -1/2

The equation: y = -1/2x + 3 |·2

2y = -x + 6 |+x

x + 2y = 6 |·2

2x + 4y = 12

Answer:

x + 2y = 8

2x + 4y = 12
