Answer:
By definition, the reference angle is an acute, hence positive angle that the terminal side of a given angle makes with the x-axis.
In this case, the acute angle is 40º.
does this graph represents a function? Why or why not?
Answer:
B. Yes, because it passes the vertical line test.
Step-by-step explanation:
B. Yes, because it passes the vertical line test.
A vertical line going from left to right will intersect at most one point on the graph at a time. That makes it a function.

ASAP If you chose Equilateral Equiangular Triangle Rotation to prove SAS Congruence, use the coordinates of your rotation to show that the two triangles are congruent by the SAS postulate. You can use the distance formula to show congruency for the sides. To show an angle is congruent to a corresponding angle, you can use slope or your compass and straightedge. (Hint: Remember when you learned how to copy an angle?) You must show all work with the distance formula for the corresponding pair of sides, and your work for the corresponding angles, to receive full credit.
Based on the SAS congruence criterion, the statement that best describes Angie's statement is:
D. Two triangles having two pairs of congruent sides and a pair of congruent angles do not necessarily meet the SAS congruence criterion, therefore Angie is incorrect.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.
An included angle is found between two sides that are under consideration.
See image attached below that demonstrates two triangles that are congruent by the SAS Congruence Theorem.
Thus, two triangles having two pairs of corresponding sides and one pair of corresponding angles that are congruent to each other is not enough justification for proving that the two triangles are congruent based on the SAS Congruence Theorem.
The one pair of corresponding angles that are congruent MUST be "INCLUDED ANGLES".
Therefore, based on the SAS congruence criterion, the statement that best describes Angie's statement is:
D. Two triangles having two pairs of congruent sides and a pair of congruent angles do not necessarily meet the SAS congruence criterion, therefore Angie is incorrect.

There are crows and groundhogs in a field. All of them together have 15 heads and 40 legs. How many of each animal are in the field?
Answer:
10 crows and 5 ground hogs
Step-by-step explanation:
10 ×2 is 20 because crows have 2 legs then we do 5×4 which is 20 because ground hogs have 4 legs 10 +5 equals 15 because each animal has one head

linear inequality: solve -4x+2
Answer:
x≤-6
Step-by-step explanation:
-4x+2≥ 26
Subtract 2 from each side
-4x+2-2 ≥ 26 -2
-4x ≥ 24
Divide by -4 remembering to flip the inequality
-4x/-4 ≤-24/-4
x≤-6
Answer:
B. x ≤ -6
Step-by-step explanation:
-4x + 2 ≥ 26
Subtract 2 on both sides.
-4x ≥ 26 - 2
-4x ≥ 24
Divide -4 on both sides.
x ≤ 24/-4
x ≤ -6
59. A car dealership has SUVs and sedans in a ratio of
5:9. How many sedans does the car dealership
have if there are 140 SUVs?
Answer:
The car dealership has 252 sedans.
Step-by-step explanation:
Number of SUVs = 140
Ratio of SUVs to sedans = 5:9
Sum of ratios = 5+9 = 14
Total number of cars = 14/5 × 140 = 392
Number of sedans = 9/14 × 392 = 252
Joshua is going to mow lawns during his summer break. The graph in the figure shows a linear relationship between the number of weeks he will be
mowing and the number of lawns he will mow. If he earns $25 for each lawn he mows, how much money will he earn after mowing lawns 5 weeks?
A. $125
B. $750
C. $1,500
D. $3,000
Answer:
$1,500
Step-by-step explanation:
We see on the graph that he mows 60 lawns in 5 weeks so if we multiply 60 by 25 because 25 is the amount of money he makes for each lawn he mows, we get 1,500 dollars.

Step-by-step explanation:
and distance of the last ramp is ______ feet (round to the nearest foot)
Answer:
The distance of the last ramp is 10 feet.
Step-by-step explanation:
From the options and the question, I assume that the height of the ramp is 6 feet. Pythagorean theorem states:
a² + b² = c²
where c is the hypotenuse, and a and b are the legs of the triangle. In this case:
6² + 8² = x²
√100 = x
10 ft = x

A. A jet rose to a height of 1000 feet above the ground. It then descended to a height of 100 feet.

A theater sold 980 tickets for a ballet. The orchestra seats cost $50 each and the
balcony seats cost $35 each. The theater collected $44, 350 in ticket sales for the
performance.
How many balcony tickets were sold?
Answer:
310 balcony tickets were sold
Step-by-step explanation:
Part 1:
X=the number of orchestra seats sold
Y=the number of balcony seats sold
980=the total of tickets sold
X+Y=980
Part 2:
Orchestra seats cost $50
Balcony Seats cost $35
Total money collected $44,350
50X+35Y=44,350
X+Y=980
Y=980-X (substitute y in your second equation)
50X+35(980-X)=44,350
50X+34,300-35X=44,350
50X-35X=44,350-34,300
15X=10,050
X=670
Y=980-X
Y=980-670
Y=310
Check
50X+35Y=44,350
50(670)+35(310)=44,350

Write an equation of the line passing through the point (7,3) that is parallel to the line 4x-7y=9
Answer:
y = -7/4x + 61/4
Step-by-step explanation:
Step 1: Write equation in slope-intercept form
-7y = 9 - 4x
y = 4/7x - 9/7
Step 2: Find slope of perpendicular line
Take the negative reciprocal of the 1st equation
m = -7/4
Step 3: Write out known variables
y = -7/4x + b
Step 4: Find b
3 = -7/4(7) + b
3 = -49/4 + b
b = 61/4
Step 4: Rewrite equation
y = -7/4x + 61/4

Does this table represent a function? why or why not?
Answer:
I think it's A but I could be wrong
Answer: B
Step-by-step explanation:
A graph or table is a function if it passes the vertical line test. That means, each x and only 1 y. One x cannot have more than 1 y because, that means it does not pass the veritcal line test. In the vertical line test, the vertival line only passes through 1 point, not 2. Since we know that this graph does not pass the vertical in test, we can eliminate C and D. We can eliminate A because 2 y-values can be the same as lone as there have different x. B fits the description of what we see on the table. Therefore, the answer is B.
Richard made tables of values to solve a system of equations. First he found
that the x-value of the solution was between 0 and 1, and then he found that it
was between 0.5 and 1. Next, he made this table.
Answer:
(0.9,4.2)
Step-by-step explanation:
Given:
The table above such that
[tex]y = -x + 5[/tex]
[tex]y = 6x - 1[/tex]
Required
Approximation of the solution
To do this, we start by equating both values of y
[tex]-x + 5 = 6x - 1[/tex]
Collect like terms
[tex]-x - 6x = -5 -1[/tex]
[tex]-7x = -6[/tex]
Divide both sides by -7
[tex]\frac{-7x}{-7} = \frac{-6}{=7}[/tex]
[tex]x = \frac{6}{7}[/tex]
[tex]x = 0.8571[/tex]
[tex]x = 0.9[/tex] (Approximated)
Substitute [tex]\frac{6}{7}[/tex] for x in any of the expression of y
Using [tex]y = -x + 5[/tex]
[tex]y = -\frac{6}{7}+ 5[/tex]
[tex]y = \frac{-6+35}{7}[/tex]
[tex]y = \frac{29}{7}[/tex]
[tex]y = 4.1[/tex] (Approximated)
The closest to this is option D
(x,y) = (0.9,4.2)

Answer:
8.5.....
Step-by-step explanation:
The length of AP is 8.5 units.
To find length of AP.
What is bisector?Bisecting a line is cutting a line exactly in half. It may also be referred to as constructing a perpendicular bisector as the line you are drawing will be at a right angle to the original line. A line, a ray, a line segment, or a point that cuts a line segment at the center dividing the line into two equal parts.
Given that:
AB=17 units
The segment bisector is a line that passes through the midpoint of a given segment.
It's a segment bisector which means the other line bisects the direct middle of AB. 17/2 is 8.5, meaning that AP should be 8.5.
AP=8.5
So, the length of AP is 8.5 units.
