Given that the measure of ∠x is 73°, and the measure of ∠y is 40°, find the measure of ∠z.
Answers
Hi,
In a triangle, all angles must add up to 180*.
73 + 40 = 113
180 - 113 = 67
Thus, the measure of Z is equal to 67

Where's the Lie?
Here are three statements that Tiana wrote about this
exponential
One of the statements is a lie. Which is it?
A. For very large values of x, the exponential has very large
values of y.
OB. The y-intercept of the exponential is (0,1).
C. The point (-2,4) is on the exponential.
Explain how you know it's a lie.
Answers
Answer:
A.
Step-by-step explanation:
As the x value is increasing the y is decreasing because the graph shows exponential decay.
The graph of a simple exponential function always pass through (0,1)
The statement that is a lie is (a) For very large values of x, the exponential has very large values of y.
From the graph, we have the following highlights
The graph passes through point (0,1); this means that the y-intercept is (0,1).The graph passes through (-2,4)The above highlights mean that options (b) and (c) are true, while option (a) is a lie
Option (a) is a lie because, as the value of x increases, the value of y increases.

Complete the point-slope equation of the line through (-1,6) and (1,5).
Use exact numbers.
Y= 6
Answers
Answer:
Y-6=-1/2(x-(-1) )
Step-by-step explanation:
The Equation for the point-slope of the line is y - 6 = -1/2(x + 1).
What is the slope of a line?A line's slope is defined as the ratio of the change in y coordinates to the change in x coordinates.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Given coordinates (-1,6) and (1,5).
the slope of line is given by,
m = (y₂- y₁)/(x₂ - x₁)
y₂- y₁ = 5 - 6 = -1
x₂ - x₁ = 1 - (-1) = 2
m = -1/2
to find the equation at y = 6
when y = 6, x = -1
the equation is given by
y - y₁ = m(x - x₁)
y - 6 = -1/2(x -(-1))
y - 6 = -1/2(x + 1)
Hence equation of a line is y - 6 = -1/2(x + 1).

For a class project, a teacher cuts out 15 congruent circles from a single sheet of paper that measures 6 inches by 10 inches. How much paper is wasted?
Answers
Answer:
60 – 15π square inches
Step-by-step explanation:
Assuming a diameter of 2 inches for each circle, then because the height of the sheet is 6 inches and the length is 10 inches, 5 columns of 3 circles each, are formed (see picture attached).
The area of each circle is: (π*D^2)/4 = (π*2^2)/4 = π square inches
The area of the 15 circles is: 15π square inches
The area of the sheet is = 6*10 = 60 square inches
The wasted paper is equal to the difference between the area of the sheet and the area of all circles, that is, 60 – 15π square inches
Answer:
60 – 15π square inches

How many people are in each row?
Answers
Answer:
8
Step-by-step explanation:
To solve this problem, you need to divide the total number of people the by the amount of rows you have to see how many people can fit in each row.
With 31 girls and 25 boys, you have a total of 56 people. Divide 56 by 7 to get 8.
You will have 8 people in each row.
Answer:
8 people.
Step-by-step explanation:
31 + 5 = 36. 36 + 20 = 56.
56 divided by the number of rows which is 7 in this case = 8.
There will be 8 people per row. Consisting of males and females.

An icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 27 mm. In cubic millimeters, how much frozen water is in the icicle? Use 3.14 for . Round your answer to the nearest hundredth.
Answers
Answer:
volume ≈ 572.27 mm³
Step-by-step explanation:
The icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 27 mm. To find how much in cubic millimetres the frozen water is in the icicle can be calculated below.
In other words the question want us to find the volume of the cylinder. The volume of the cone can be represented as follows:
volume of a cylinder = 1/3πr²h
where
r = radius
h = height
diameter = 9 mm
height = 27 mm
r = diameter/2 = 9/2 = 4.5
volume = πr²h
volume = 1/3 × 3.14 × 4.5² × 27
volume = 1/3 × 3.14 × 20.25 × 27
volume = 1/3 × 63.585 × 27
volume = 1716.795/3
volume = 572.265 mm³
volume ≈ 572.27 mm³
Answer:
572.27 mm³

A square in a rectangle have the same perimeter. The length of a side of the square is 4x-1. The length of the rectangle is 2x+2 and the width is 2x
Answers
The value x is 1, if the perimeter of square and rectangle are same. The perimeter of square and rectangle is 12 units.
Step-by-step explanation:
The given is,
A square in a rectangle have the same perimeter
The length of a side of the square is 4x-1
The length of the rectangle is 2x+2 and width is 2x
Step:1
Let, a - Side of square
l - Length of the rectangle
w - Width of the rectangle
Step:2
Formula for perimeter of square is,
[tex]p=4a[/tex].............................(1)
Formula for perimeter of rectangle is,
[tex]p=2(l+w)[/tex]....................(2)
Step:3
From given,
Equation (1) = Equation (2)
[tex]4a = 2 (l+w)[/tex]
where,
a = 4x-1
l = 2x+2
w = 2x
Substitute the values,
4 ( 4x-1 ) = 2 ( 2x+2+2x )
16x - 4 = 2 (4x + 2)
16x - 4 = 8x + 4
16x - 8x = 8
8x = 8
x = 1
Step:4
Substitute the values of x,
a = 4(1)-1 = 3
l = 2(1)+2) = 4
w = 2(1) = 2
Perimeter of square and rectangle is 12 units
Result:
The value x is 1, if the perimeter of square and rectangle are same. The perimeter of square and rectangle is 12 units.

Point A (-3, 5) is rotated 180º about the origin. What are the coordinates of A' after the rotation?
Answers
A point when rotated 180º about the origin flips the sign of the coordinates. Thus, point A' after rotating point A (-3,5) 180º about the origin would have coordinates (3,-5).
Explanation:A rotation of 180º about the origin essentially changes the signs of the coordinates. If we have Point A as (-3, 5), after a 180° rotation about the origin, you'll get Point A', which will be the opposite of Point A. That means it turns (-3, 5) to (3, -5).
Rotation about the origin flips the point across both axes. This is based on a rule in mathematics: When we rotate a point 180° about the origin, (x, y) becomes (-x, -y).
The coordinates of A' after the 180° rotation are (3, -5).

.
What is the mass of the wooden cube?
Enter your answer in the box.
g
Answers
Answer:
153.36g
Step-by-step explanation:
Density is defined as the ratio of mass per unit volume of a material.
Density = Mass/Volume
Given the edge of a cube which is equivalent to its length L to be 6cm.
Density of the cube = 0.71g/cm³
Volume of the cube = L³
Volume = 6³
Volume of the cube = 216cm³
Mass = Density × Volume
Mass of the cube = 0.71×216
Mass of the cube = 153.36grams
Answer:
153.36 grams
Step-by-step explanation:
Density is mass divided by volume: d = m/v.
Here, we already know that d = 0.71 g/cm³.
We can find the volume of hte cube. The volume of a cube is denoted by:
V = s³, where s is the side length
The cube's length is 6, so plug this in:
V = s³
V = 6³ = 216 cm³
Plug these values in:
d = m/v
0.71 g/cm³ = m / 216 cm³
m = 0.71 * 216 = 153.36 grams
The answer is 153.36 grams.
