Answer:
The angle yo measures 40º.
Step-by-step explanation:
Given that the sum of yo and 50 ° is a right angle, to find the value of yo the following calculation must be performed, knowing that a right angle measures 90 °:
50 + yo = 90
yo = 90 - 50
yo = 40
Therefore, the angle yo measures 40º.
Answer: Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (3, -1)
Focus: (3, - 3/4)
Axis of Symmetry: x = 3
Directrix: y = - 5/4
Step-by-step explanation:

Answer:the price for one shirt is $7.5
the price for one pair of pants is $18.5
Step-by-step explanation:
Let x represent the price for one shirt.
Let y represent the price for one pair of pants.
Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. This means that
4x + 3y = 85.5 - - - - - - - - - -1
She returns the next day and buys three shirts and five pairs of pants for $115.00. This means that
3x + 5y = 115 - - - - - - - - - - - 2
Multiplying equation 1 by b3 and equation 2 by 4, it becomes
12x + 9y = 256.5
12x + 20y = 460
Subtracting, it becomes
- 11y = - 203.5
y = - 203.5/ -11 = 18.5
Substituting y = 18.5 into equation 1, it becomes
4x + 3×18.5 = 85.5
4x + 55.5 = 85.5
4x = 85.5 - 55.5 = 30
x = 30/4 = 7.5
Answer:
Step-by-step explanation:
I will give you the answer in the following steps. In addition to solving this exercise it is necessary the table found in the attachments -And that was probably in the book where this exercise is taken-.
Here we have:
Percentage Method of Withholding –Single Person
Each Weekly Allowance = $63.46
Step 1:
= ∙
=3*$63.46
= $190.38
Step 2:
=−
=$560.00- $190.38
=369.62 US$
Step 3: (Here we refer to the table, as the income is less than $ 645, and more than $ 195, the tax is 14.40 plus 15% for being the income above $ 195)
ℎℎ=$14.40+[15%*($369.62−195)]
ℎℎ= $40.59
