Answer:
32
Step-by-step explanation:
In order to find the measure of angle A we must first find x
If you didn't know, supplementary angles add up to equal 180
Hence, 2x - 16 + 5x + 28 = 180
( Note that we just created an equation that we can use to solve for x )
We now solve for x using the equation that we created
2x - 16 + 5x + 28 = 180
Combine like terms
7x + 12 = 180
Subtract 12 from both sides
7x = 168
Divide both sides by 7
We're left with x = 24
Now to find Angle a
To find Angle A we simply substitute 24 for x in 2x - 16
* Substitute 24 for x *
2(24) - 16
Multiply
48 - 16
subtract
/_ A = 32
You just hung a picture twelve inches above the wall trim. Your friend thinks the
picture looks crooked. Use what you know about parallel lines and transversals to
determine if the picture is level.
Step 1: You don't have a level, but you are in luck. You know the wall trim is level.
You have a protractor and the sun is casting a shadow on the wall. Describe how
you can determine if the picture is level.
: Assume you measured ∠3 and ∠5 and found them to be equal. Use the
spaces provided below to complete a formal proof that demonstrates the picture
is level with the trim.
Answer:
The angles measured between the shadow and the wall trim and the shadow and the top or bottom of the picture should be equal if the picture is level
Step-by-step explanation:
Whereby the picture is 12 inches above the wall trim and the Sun is casting a shadow on the wall, therefore, the edges of the shadow of a straight edged object is straight
If the picture is level, the shadow cast by the sun is transversal to the wall trim and the line formed by extending the bottom or top of the picture in the direction of the shadow. That is, if the picture is parallel, the shadow cast by the Sun on the wall is transversal to the picture and the wall trim if or when the shadow eventually crosses the picture
With the protractor, the angle between the shadow and the wall trim and the shadow and the top or bottom is measured
The angles measured should be the same if the picture is level.
I hope this is correct. If not feel free to let me know and I will fix it. I'm sorry in advance if it is wrong.
Sandy went to her local zoo where 50% of it's exhibits featured reptiles. If the zoo features 44 exhibits in total, then how many of the zoo's exhibits feature reptiles?
Answer:
22 exhibits
Step-by-step explanation:
We are told from the above question that:
Sandy went to her local zoo where 50% of it's exhibits featured reptiles.
If the zoo features 44 exhibits in total, then the number of the zoo's exhibits that feature reptiles is calculated as:
50% of 44
50/100 × 44
= 50 × 44/100
= 22
Therefore, the number of the zoo's exhibits that feature reptiles is 22 exhibits.

Determine whether the sequence is arithmetic or geometric. Sequence 1: –10, 20, – 40, 80, ... Sequence 2: 15, – 5, – 25, – 45, ... Which of the following statements are true regarding Sequence 1 and Sequence 2.
Answer:
geometric
arithmetic
Step-by-step explanation:
there are no statements to check. you did not copy them in.
but I can solve the first part of the question.
sequence 1 :
-10, 20, -40, 80, -160, 320, -640, ...
I extended the sequence by a few more terms.
but it is clear that each new term is the previous term multiplied by -2.
since the sequence is built by multiplication, it is geometric.
sequence 2:
15, -5, -25, -45, -65, -85, ...
so, it is clear that each new term is the previous term subtracted by -20.
since the sequence is built by adding or subtracting, it is arithmetic.

One factor of this is (x - 4). Find the other factor.
Answer:
(3-x) is the other factor.
Step-by-step explanation:
The given function is :
[tex]F(x)=-x^{2}+7x-12[/tex]
One of the factor is (x-4)
We need to find the other factor.
It can be solved as follows :
[tex]F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)[/tex]
So, the other factor is (3-x).

975 toffees are to be distributed among 23 children. Estimate the numbers of toffees that each child will get in nearest tens.
Answer:
40
Step-by-step explanation:
Total number of toffees = 975
Total number of children = 23
Estimate the numbers of toffees that each child will get in nearest tens.
Number of toffees each child get = Total number of toffees / Total number of children
= 975 / 23
= 42.391304347826
Approximately,
Number of toffees each child get = 40 to the nearest tens

Now that you know the height of the cone how can you solve for the slant height?
Answer:
imagine a triangle
one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.
remember the pythagoras stuff
so
(slantheight)² = radius² + height²
or finally:
slantheight = squareroot (radius² + height²)

High population density can cause increases in competition for resources, such as food and shelter. The table shows the number of zebras living in four different regions.
A 3-column table has 4 rows. The first column has entries Region A, Region B, Region C, Region D. The second column is labeled Population of Zebras with entries 1,312, 630, 16,400, 17,800. The third column is labeled Area (kilometers squared) with entries 212, 314, 625, 902.
In which region is competition for resources most likely the greatest?
Region A
Region B
Region C
Region D
Answer:
C
Step-by-step explanation:
magic
The region with the competition for resources is region C with the highest population density
What is Population Density?The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.
Population density = number of people / the area they occupy
Given data ,
Let the population density be represented as P
Region Population Area
A 1,312 212
B 630 314
C 16,400 625
D 17,800 902
Now , the state with the highest population density will have the greater competition for the resources
So , The population density in Region A = 1312 / 212 = 6.19
The population density in Region B = 630 / 314 = 2
The population density in Region C = 16400 / 625 = 26.24
The population density in Region D = 17800 / 902 = 19.7
Hence , the region C has the highest population density

I really need help do can someone do it step by step so I can understand plzzzz
Answer:
64 × pi m²
Step-by-step explanation:
the formulas needed for the surface area of a cone are :
base area plus the "mantle", the lateral "wall" around it.
the base area is a circle.
so, that formula is Ac = pi×r²
the "wall" formula is Aw = pi×r×s
r = radius
s = slant height = 12
the formula for the surface area of a sphere is
As = 4×pi×r²
we know now, that both surface areas are the same, and also the radius is the same for both objects.
Ac + Aw = As
pi×r² + 12×pi×r = 4×pi×r²
=>
12×pi×r = 3×pi×r²
12×pi = 3×pi×r
12 = 3×r
r = 4 m
now, we only need to use this value of r in our formulas for surface areas, like for the sphere :
4×pi×r² = 4×pi×4² = 4³×pi = 64×pi
