Answer:
71
Step-by-step explanation:
Answer:
3)
Step-by-step explanation:
152 - 90 = 62
180-152 = 28 which <CED and <BAC = 28.
180-28-43 = 109
<ACD = 71 because if <ACB = 109. then think of DCB as a 180 degree. 180-109. then it is 71.

Answer:
16.75 meters
Step-by-step explanation:
This problem is a plug in problem.
H = 0.20x + 12.75
we plug in 20 for x which gives us
(0.20 * 20) + 12.75
which equals
4 + 12.75
giving us
16.75 meters
Answer:
16.75 meters
Step-by-step explanation:
First of all, in this x=20
let's plug it in
y=0.20×20+12.75
y=4+12.75
y=16.75

The table shows the amount of money Tyler earns for mowing lawns. Is the
relationship a proportional relationship? Complete the explanation.
Answer:
The constant of variation 'k' is NOT constant.
Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.
Step-by-step explanation:
Given the table
Number of Lawns 1 2 3 4
Amount Earned ($) 16 32 54 72
We know that when y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where 'k' is called the constant of proportionality.
In our case, the 'Amount earned ($) ' is represented by 'y', and the 'Number of Lawns' is represented by 'x'.
Let us check the constant of proportionality using the equation
k = y/x
k = 16/1 = 16
k = 32/2 = 16
k = 54/3 = 18
k = 72/4 = 18
It is clear that that the constant of variation 'k' is NOT constant.
Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.

Answer:
Equation → 5y = 3y + 6
Value of ST = 15
Step-by-step explanation:
From the picture attached,
In right triangles ΔVST and ΔVUT,
Acute angles ∠SVT ≅ ∠UVT [Given]
TV ≅ TV [By reflexive property of congruence]
ΔVST ≅ ΔVUT [Hypotenuse angle congruence of right triangles]
Therefore, corresponding parts of the congruent triangles are congruent.
Therefore, ST ≅ TU
5y = 3y + 6
5y - 3y = 6
2y = 6
y = 3
Therefore, ST = 5y
ST = 5(3)
= 15

Many adults are selected at random to respond to a survey about their favorite season and whether they have allergies or not. The two-way table summarizes the results from the survey.
Which season is the least popular in this group? 1. winter 2. spring 3. summer 4. fall
How many more people have allergies than people without allergies in this group?
How many people were surveyed in this group?
Answer:
1. spring
2. 21
3. 225
Step-by-step explanation:
102-123=21
all the numbers added equal 225
The solution is
A) The season which is least popular is Spring
B) The number of people who have more allergies than the non-allergic group is 21 people
C) The total number of people surveyed is 225 people
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the Allergic group be = A
Let the non-allergic group be = B
Now , the equation is given as
Allergic Group A = { Winter = 43 , Spring = 12 , Summer = 35 , Fall = 33 }
Non-Allergic Group B = { Winter = 21 , Spring = 13 , Summer = 33 , Fall = 35 }
A)
To find the lease popular season
Find the number in the group which has the least values
So , the Spring season of Group B has the least number of people
Therefore , the spring season of non-allergic group is least popular
B)
The total number of Allergic people = Total sum of Allergic group A
So , the equation will be
Sum of Group A = 43 + 12 + 35 + 33
Sum of Group A = 123 people
Now ,
Total number of non-allergic people = Total sum of non-allergic group B
So , the equation will be
Sum of Group B = 21 + 13 + 33 + 35
Sum of Group B = 102 people
So , the difference between Group A and Group B = 123 - 102
= 21 people
Therefore , a total of 21 people were more in allergic group
C)
The total number of people surveyed = Sum of Group A + Sum of Group B
So , the equation will be
The total number of people surveyed = 123 + 102
The total number of people surveyed = 225 people
Therefore , The total number of people surveyed is 225 people
Hence ,
A) The season which is least popular is Spring
B) The number of people who have more allergies than the non-allergic group is 21
C) The total number of people surveyed is 225 people

y=2x+3 -----(i)
y=-x-9 ------(ii)
now, putting value of equation (i) in (ii)
y= -x-9
or, 2x+3 = -x-9
or, 2x+x = 9-3
or, 3x = 6
or, x = 6/3
or, x = 2
again,
y = 2x+3
or, y = 2×2+3
or, y = 7
therefore, value of X and Y are 2 and 7 respectively.

John works for a company that cuts down dead trees for the city. He needs to determine the height of the tree to ensure safety. He chooses a point 10 m from the base of the tree. From this point, the angle of elevation to the top of the tree is 46°. Determine the height of the tree to the nearest tenth of a meter.
Answer:
10.4m
Step-by-step explanation:
We solve the above question using the Trigonometric function of Tangent.
The formula is given as:
tan θ = Opposite/Adjacent
θ = Angle of Elevation = 46°
Opposite = Height of the tree = x
Adjacent = Distance from the base of the tree = 10m
Hence:
tan 46 = x/10
Cross Multiply
x = tan 46 × 10
x = 10.355303138m
Approximately to the nearest tenth = 10.4m

Planes Q and R are parallel. Lines a and b are shown on planes Q and R, respectively. Planes Q and R are parallel. Plane Q contains line a and plane R contains line b. Both lines are going in different directions. Which statement is true about lines a and b?
Answer:
They are skew lines.
Step-by-step explanation:
Which statement is true about lines a and b?
They are parallel lines.
They are perpendicular lines.
They are skew lines.
They will intersect.
As they both are in different directions they are skew lines .
Skew lines are not parallel neither they .They are also not co planar i.e they lie in different planes.
We have two plane Q and R . We have two line a and b on the different planes Q and R. Both planes are parallel but the lines a and b are in different directions. Therefore they are skew lines . They do not intersect and are also not parallel neither co planar.
