Answer:
x = 4.4
Step-by-step explanation:
The ratios of corresponding sides are in proportion , that is
[tex]\frac{x}{11}[/tex] = [tex]\frac{4}{10}[/tex] ( cross- multiply )
10x = 44 ( divide both sides by 10 )
x = 4.4

Given m<4 =35, m<1= m<2 + m<4.
Prove m<3 = 70
Answers
Answer:
given m<4 = 35° and m<1 = m<2 + m<4
prove m<3 = 70°
Statements Reasons
m<4 = 35° given
m<1 = m<2 + m<4 given
m<2 = m<4 by the vertical angles theorem
35° = 35° substitution property of equality
m<2 + m<4 = m<1 angle addition postulate
35° + 35° = 70° substitution property of equality
m<3 = m<1 by the vertical angles theorem
m<3 = 70° substitution property of equality
The two column proof for the given set of angles are:
m∠2 = m∠4 by the vertical angles theorem
m∠3 = m∠1 by the vertical angles theorem
Given data:
The measure of angle
The measure of angle m∠4 =35,
The measure of angle m∠1= m∠2 + m∠4.
Now, Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Therefore, m∠2 = m∠4 by the vertical angles theorem
m∠3 = m∠1 by the vertical angles theorem
35° + 35° = 70° substitution property of equality
Hence, the measure of angle m∠3 = 70°

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have
budgeted $4,000 for their reception. If the reception hall charges a $50 cleanup fee plus $35 per person, find the greatest number of people that they may invite and still stay within their budget.
Answers
Answer:
They can invite at max 112 people.
Step-by-step explanation:
4000 - 50 = 3950
3950 / 35 = 112.85 (Can't round up to 113 because then it will go over their budget), so you will get 112 people.

Answer:
∠a = 133°∠b = 15°∠c = 75°∠d = 58°Step-by-step explanation:
We don't know the definitions, properties, postulates, or theorems on your list, so we'll use the following:
a right angle measures 90°a straight angle measures 180°the acute angles in a right triangle total 90°an exterior angle of a triangle is equal to the sum of the remote interior anglesthe measure of an angle is equal to the sum of the measures of its parts.__
∠a = 180° -47° = 133°; reasons 2, 5. The angles form a straight angle.
∠b = 47° -32° = 15°; reason 4
∠c = 90° - ∠b = 90° -15° = 75°; reason 3
∠d = 90° -32° = 58°; reasons 1, 5. The angles form a right angle. If you want to get picky, we know it is a right angle by reasons 1 and 2. The marked right angle and the sum of 32° and ∠d together form a straight angle.

Finally, suppose you decide not to finance (get a loan for) the car and to
wait two years to save up money in addition to the $4,000 you already
have saved for the car.
How much money would you have to save each month in order to
purchase this car without any financing (loan) at the end of two years?
Round your answer to the nearest cent.
Answers
Supposing a cost of $30,000, and using proportions, it is found that you would have to save $1,083.30 each month.
--------------------------
We suppose a cost of $30,000.You already have $4,000 saved.30 - 4 = 26, thus, you would need to save $26,000 in 2 years = 24 months.How much per month?We can solve it using proportions, by the following rule of three:
1 month - $x
24 months - $26,000
Applying cross multiplication:
[tex]24x = 26000[/tex]
[tex]x = \frac{26000}{24}[/tex]
[tex]x = 1083.3[/tex]
You would have to save $1,083.30 each month.

Write an equation of the line in slope intercept form for (0,3) and (4,2)
Answers
Answer: 13
Step-by-step explanation:
Step-by-step explanation:
the slope is the y/x ratio of the y and x coordinate differences when going from one point to the other. and it is always the factor of x in the equation.
x changes by 4 units (from 0 to 4), y changes by -1 unit (from 3 to 2).
so, the slope is -1/4.
the intercept means the intercept with the y-axis. and that means the y value when x = 0. which is given already by the first point : 3
so, the equation is
y = -1/4 x + 3
Solve for x.
