Answer:
The polygons are similar.
Step-by-step explanation:
By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.
Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.
The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is [tex]\frac{3}{3.75}[/tex].
The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is [tex]\frac{5}{6.25}[/tex].
If these polygons are similar, these proportions must be equal.
[tex]\frac{3}{3.75}=\frac{5}{6.25},\\0.8=0.8\:\checkmark[/tex]
Checking, we see that these proportions are equal, and therefore the polygons are similar.
Iliana cubed the number of flowering plants in her garden, then added 2 vegetable plants. Let p represent the original number of plants in her garden. Which shows an expression to represent the total number of plants in her garden and the total number of plants if p = 3?
Answer:
p³+2; 29 plants
Step-by-step explanation:
Hi there!
Find the expression to represent the total number of plants in her garden
p
First, we're told that Iliana cubed the number of flowering plants in her garden. This means she raised the original number of plants by an exponent of 3.
p³
Then, we're told that she added 2 vegetable plants.
p³+2
Find the number of total plants if p=3
p³+2
= (3)³+2
= 27+2
= 29
Therefore, Iliana now has 29 plants in total.
I hope this helps!

The double cone is intersected by a vertical plane passing through the point where the tips of the cones meet. What is the shape of the cross section formed?
I have attached a picture of the double cone.
I have also attached the options missing.
Answer:
Option B is correct
Step-by-step explanation:
From the image of the double given, when we cut a section vertically through the centre where the tips of the cones meet, when we look at the cut section, we will not see curves but straight lines meaning that the top and bottom will be horizontal lines and not curves.
Also, the meeting point of the two cone tips will remain the same.
Looking at the options, the only one that fulfills the condition is option B.

B

Answer:
z = 45 (it is the same angle as x)
y and u = 135
Step-by-step explanation:
45 + 45 = 90
360 - 90 = 270
270/2 = 135
CHECK YOUR WORK:
135 + 135 + 45 + 45 = 360
270 + 90 = 360
360 = 360
Answer:
z = 45
y = 135
u = 135
Step-by-step explanation:
Vertically opposite angles are equal so x and z must be the same.
A circle is 360 degrees so
360 - (45 + 45) = 270
270 / 2 = 135 degrees
This means that y and u must both be 135 as they too are vertically opposite.
can someone help me plss

The mean temperature of 10 cups of coffee is 89.6°C. The mean temperature of a different collection of 20 cups of coffee is 92.1 °C. What is the mean temperature of all 30 cups of coffee?
Answer:
91.3 degrees celsius
Step-by-step explanation:
Here, we want to calculate the mean temperature of the 30 cups
From what we have here, if we multiplied the mean by the count of cups, we have the total
That means, we have the total temperature of all as;
(10 * 89.6) + (20 * 92.1) = 2,738
So to get the temperature of the thirty, we divide this by 30 as follows;
2,738/30 = 91.3

Use the empirical rule to calculate the percentage of individuals who sleep between and hours per day. At least
Answer:
Following are the solution to the given question:
Step-by-step explanation:
For point a:
[tex]6.5 - 4.9 = 2.4 \\\\\frac{2.4}{1.2} = 2 \\\\\sigma \ \ so \ k = 2[/tex]
For point b:
[tex]\frac{3}{1.2}\ \ \sigma\ \ so \ k =\frac{3}{1.2} \ \ so\ \ 1- \frac{1}{k ^2} = 0.84[/tex]
For point c:
Once again, we have k = 2 though with Chebyshev discrepancy of witness numbers in the same number of standard deviations off mean = at least 75 percent.

Answer:
Step-by-step explanation:
f(x) = px + q
f(-2) = 4
p*(-2) + q = 4
-2p + q = 4 -----------------(I)
f(3) = 4
p*3 + q = 4
3p + q = 4 ---------------------(II)
Subtract equation (II) from (I)
(I) -2p + q = 4
(II) 3p + q = 4 {Subtract}
- - -
-5p + 0 = 0
-5p = 0
p = 0
Plugin p = 0 in equation (I)
0 + q = 4
q = 4
p = 0
q = 4

Find the unknown for every letter
Answer:
x = 70°, y = 110°, z = 70°
Step-by-step explanation:
The two straight lines are intersection each other.
y = 110° [justification vertical angles, or vertically opposite angles]
x + 110° = 180 [supplementary angles]
therefore x = 180-110 = 70°
Similarly,
z + 110° = 180 [supplementary angles]
therefore z = 180-110 = 70°
Answer:
Y= 110°
Z= 70°
X= Z, which is 70°
Step-by-step explanation:
Because 110° is same to y, y=110°.
A 180° angle is a straight line, so 180-110=70.
Thus, z is 70°
Because x is same to z, it is 70° too.

Answer:
Reflex AngleStep-by-step explanation:
All the measuring angles above 180 degrees and less than 360 degrees are termed Reflex angles.

x-124=9(2x+3)-15 ???
Answer:
x = - 8
Step-by-step explanation:
x - 124 = 9(2x + 3) - 15
x - 124 = 18x + 27 - 15
x - 124 = 18x + 12
x - 124 + 124 = 18x + 12 + 124
x = 18x + 136
x - 18x = 18x - 18x + 136
- 17x = 136
- 17x ÷ - 17 = 136 ÷ - 17
x = - 8
Graph the second equation to find the solution of the system of equations.
y = –x,
y = 2x + 6
What is the point of intersection
Answer:
So the point of intersection would be -x=2x+6
and then we'll subtract 2x on both sides and get -3x=6
this will result in x=-2
Then we'll substitute that into y=-x, so y=2
Therefore the point of intersection is (-2,2)

Coopersville Middle School raised $71,875 on their sub sale. There were 575 students selling subs. What was the average amount of money raised by each student?
Answer:
$125
Step-by-step explanation:
Coopersville middle school raised 71, 875 on their sale sub
There are 575 students in the school
Therefore the average amount raised by each student can be calculated as follows
°= 71875/575
= 125
Hence the average amount raised by each student is $125
Round off 2/3 correct to 2 significane figures
=====================================================
Explanation:
Use of a calculator will show that
2/3 = 0.6666...
where the 6's go on forever. Your teacher only wants 2 significant figures though. That means you'll round to the nearest hundredth to get 0.67
The 0 to the left of the decimal point is not a significant figure. The reason being is because we can rewrite 0.67 into 6.7*10^(-1); we can see the coefficient 6.7 having two sig figs.
Hayden is creating triangles using plastic straws cut to various lengths for the sides. Which set of straw lengths can he use to create a scalene triangle?
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.
A scalene triangle is a triangle in which all the three sides of the triangle have different lengths hence, all the angles of the triangle also have different lengths.
Therefore the set of straw lengths that can be used a scalene triangle must have different lengths, for example:
5, 7 , 8
