Answer:
Angle at x is 75°
Step-by-step explanation:
Data :
Angle at A = 65°
Angle at B = 40°
According to the porperty of triangle we know that total interior angle a triangle has is 180° irrespect of type or size
A + B + C = 180
65 + 40 + C = 180
C = 180 - 65 - 40 = 75°

If the metal used to construct the spinner costs $13. 25 per square centimeter, how much will it cost to make this part of the compass? Round to the nearest cent. Cost = $.
Answer:
129.82
Step-by-step explanation:
I got the right answer
The cost to make the spinner is $132.50.
The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. The base of each of these triangles is 2 centimeters and the legs are 5 centimeters.
The area of each triangle is (1/2) * base * height = (1/2) * 2 * 5 = 5 square centimeters.
The total area of the spinner is 2 * 5 = 10 square centimeters.
The cost to make the spinner is 10 * $13.25 = $132.50.
Rounded to the nearest cent, the cost is $132.51.
Here is the calculation:
Area of each triangle = (1/2) * base * height = (1/2) * 2 * 5 = 5 square centimeters
Total area of the spinner = 2 * 5 = 10 square centimeters
Cost to make the spinner = 10 * $13.25 = $132.50
Rounded to the nearest cent, the cost is $132.51

find the slope of each line
please help i am confused,
Answer:
Slope: 3
Step-by-step explanation:
There are two ways to solve this, one is more algebraically, and one is more logically.
Algebraically:
When only a graph is available to us as a resource, we can use a method called rise-over-run, which looks like this [tex]\frac{y}{x}[/tex].
Now, we select 2 points on the graph that are real integer values, meaning they aren't decimals. I will use (3,-2) and (4,1)
When we use rise-over-run we subtract the y-values and the x-values from each over before dividing. [tex]\frac{1-(2)}{4-3} = 3/1=3[/tex]
Logically:
We can use something called a "slope triangle" to find the slope. We will connect the same 2 points mentioned before.
We will draw a triangle to the right of the two points. I will attach a screenshot.

A globe company currently manufactures a globe that is 16 inches in diameter. If the dimensions of the globe were reduced by half, what would its volume be? Use 3. 14 for π and round your answer to the nearest tenth. 682. 7 in3 2143. 6 in3 85. 3 in3 267. 9 in3.
Volume is the space occupied by an object. The volume of the globe is 268.0825 in³.
What is the volume of a sphere?The volume of the sphere is given by the formula,
[tex]\text{Volume of Sphere}= \dfrac{4}{3} \pi r^3[/tex]
We know that the diameter of the globe is reduced to half, therefore, the diameter of the globe,
[tex]\rm \text{New Diameter of the globe} = \dfrac{Diameter}{2} = \dfrac{16}{2} = 8\ inches[/tex]
Also, the radius of the globe is half of its diameter,
[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{8}{2} = 4\ inches[/tex]
We know that the shape of a globe is spherical, also, we know the formula of the volume of the sphere, therefore, the volume of the globe can be written as,
[tex]\begin{aligned}\text{Volume of Globe}&= \dfrac{4}{3} \pi r^3\\\\& =\dfrac{4}{3} \pi (4)^3\\\\&=268.0825\rm\ in^3 \end{aligned}[/tex]
Hence, the volume of the globe is 268.0825 in³.

Perimeter= 20 inches
Step-by-step explanation:
since the perimeter of a plane figure is distance round the shape, we add all the sides in order to get 20inches.
Perimeter= 4+5+4+4+3= 20incjes. That's for the perimeter.
Then area, we divide the shape into two portions sides A and B.
We find the area of side A which is a rectangle so, the are = Length×Breadth..
= 4×5 = 29cm².Side B is a triangle so it's area will be
Answer:
Total Perimeter = 30 in
Total Area: 30 in²
Step-by-step explanation:
First, do the perimeter of the triangle.
Equation: side+side+base = 3 + 4 + 5 = 12
Next is the perimeter of the rectangle.
Equation: 2(length + width) = 2·(5 + 4) = 18
Then, add the two perimeters:
12 + 18 = 30 in (Total Perimeter = 30 in)
Next, do the area of the triangle.
Equation: height • base/2 = 4 · 5/2 = 10
Finally, the area of the rectangle.
Equation: width • length = 4 · 5 = 20
Then, add the two areas:
10 + 20 = 30 (Total Area: 30 in²)

What is the volume of a right circular cylinder with a base diameter of 17. 5 ft and a height of 24. 5 ft? Enter your answer in the box. Use 3. 14 for pi and round only your final answer to the nearest hundredth.
Right circular cylinder has its height as the straight line connecting centers of its top and bottom circle. The volume of given cylinder is: 5889.95 cubic feet.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi \times r^2 \times h \: \rm unit^3[/tex]
For the given case, the considered right circular cylinder has these dimensions:
Its base diameter = 17.5 ft
Its height = 24.5 ft
Since radius is half of diameter, thus, radius of considered cylinder = 17.5/2 = 8.75 ft
Thus, using the formula for volume of right circular cylinder, we get:
[tex]V = \pi \times r^2 \times h \: \rm unit^3\\V \approx 3.14 \times (8.75)^2 \times (24.5) \approx 5889.95 \: \rm ft^3[/tex]
Hence, the volume of given cylinder is: 5889.95 cubic feet.

How to solve it
Answer:
x=1 and y=4/5
Step-by-step explanation:
Given system of equations
3x+5y=7
5x+10y=13
Multiply first equation by 2
2(3x+5y)=2(7)
6x+10y=14
Eliminate y-variable to get "x"
6x+10y=14
- 5x+10y=13
x = 1
Substitute x=1 into either equation and find "y"
3x+5y=7
3(1)+5y=7
3+5y=7
5y=4
y=4/5
Therefore, x=1 and y=4/5

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes weigh 25 pounds each. There
are 125 boxes in all. If the truck is carrying a total of 4625 pounds in boxes, how many of each type of box is it carrying?
Number of large boxes =
Number of small boxes =
Answer:
There are 50 large boxes.
There are 65 small boxes
Step-by-step explanation:
First, "boxes of two sizes" means we can assign variables:
Let x = number of large boxes
y = number of small boxes
"There are 115 boxes in all" means x + y = 115 [eq1]
Now, the pounds for each kind of box is:
(pounds per box)*(number of boxes)
So,pounds for large boxes + pounds for small boxes = 4125 pounds"the truck is carrying a total of 4125 pounds in boxes"
(50)*(x) + (25)*(y) = 4125 [eq2]
It is important to find two equations so we can solve for two variables.
Solve for one of the variables in eq1 then replace (substitute) the expression for that variable in eq2. Let's solve for x:
x = 115 - y [from eq1]
50(115-y) + 25y = 4125 [from eq2]
5750 - 50y + 25y = 4125 [distribute]
5750 - 25y = 4125
-25y = -1625
y = 65 [divide both sides by (-25)]
There are 65 small boxes.
Put that value into either equation (now, which is easier?) to solve for x:
x = 115 - y
x = 115 - 65
x = 50
There are 50 large boxes.
