Two angles are a linear pair. One third of the measure of the first plus 12 is equal to the measure of the second. what are the measures of both angles?
Answer:
Step-by-step explanation:
Let's angle be x and y
Then......
⅓x+12=y......eqn(I)
Since are linear
x+y=180
y=180-x.....eqn(ii)
Substitute the eqns
You get x=126°
From eqn (iii)
You get y=54°
Those are angles
The measures of both angles are 126° and 54°.
What are Linear Pair of Angles?Linear pair of angles are the pair of angles formed when two lines are intersected at a point forming on a line.
Sum of the measures of angles of linear pair is supplementary.
Given that,
Two angles are a linear pair.
Let x and y be the measures of two angles.
We have,
y = 1/3 x + 12
Sum of the angles is supplementary.
x + y = 180
x + 1/3 x + 12 = 180
4/3 x = 168
x = 126°
y = 180 - 126 = 54°
Hence the angles are 126° and 54°.

Diego can make 12 bags without having any cookies left over, ensuring each bag contains an equal number of each flavor.
To determine how many bags Diego can make without having any cookies left over, we need to find the greatest common divisor (GCD) of the quantities of each type of cookie.
Step 1:
Find the GCD of the quantities of each type of cookie:
GCD(48, 64, 100) = 4
Step 2:
Calculate the number of bags Diego can make:
Each bag will contain 4 cookies of each flavor, as determined by the GCD.
For chocolate chip cookies: 48 cookies ÷ 4 cookies/bag = 12 bags
For vanilla cookies: 64 cookies ÷ 4 cookies/bag = 16 bags
For raisin cookies: 100 cookies ÷ 4 cookies/bag = 25 bags
Step 3:
Determine the minimum number of bags Diego can make without any cookies left over:
The minimum number of bags is determined by the smallest number of bags he can make for any type of cookie, which is 12 bags for chocolate chip cookies.
Therefore, Diego can make 12 bags without having any cookies left over.

The length of the minute hand on a clock is 5 in....is it a dimeter, circumference, radius?
Answer: Radius
Step-by-step explanation: The radius of a circle is a segment that joins the center of the circle to a point on the circle.
The minute hand on a clock would start in the center and go outwards towards a certain number. However, the minute hand would not go the full length across the clock so it's not the diameter.
The circumference of a circle which is another way of saying the perimeter of the circle is the distance around the circle so it would not be the circumference.
This means that the minute hand would represent the radius of a clock.
The 5 inch length of the minute hand on the clock is actually a radius, not a diameter or circumference. This radius is the distance from the center of the clock face to the tip of the minute hand. The diameter, which would be twice the length of the radius, would be 10 inches, and the circumference of the circle formed by the minute hand's movement would be approximately 31.4 inches.
Explanation:In this case, the 5 inches refers to the radius of the circle that is created by the minute hand of the clock as it moves around the clock face. This radius is the distance from the center of the clock face to the tip of the minute hand. In general, in any circular motion, the length of the revolving component, like a clock hand, from the center to its tip is called the radius of the circle.
The diameter is simply twice the radius, and in this case if the radius is 5 inches, the diameter would be 10 inches. The circumference of a circle is calculated by the formula 2πr (2 times the value of pi times the radius), hence, in this instance, it would be 10π inches or approximately 31.4 inches.

8 km + 2300 m +12,000 cm = ?
Answer:
The result is 10.42 kilometers, or 10,420 meters or 1'042,000 centimeters.
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
8 kilometers plus 2,300 meters plus 12,000 centimeters
2. Let's do the conversions to find the result either in kilometers, meters or even centimeters.
A. In kilometers:
8 kilometers
2,300 meters = 2.3 kilometers
12,000 centimeters = 120 meters = 0.12 kilometers
10.42 kilometers
B. In meters
8 kilometers = 8,000 meters
2,300 meters
12,000 centimeters = 120 meters
10,420 meters
C. In centimeters
8 kilometers = 8,000 meters = 800,000 centimeters
2,300 meters = 230,000 centimeters
12,000 centimeters
1'042,000 centimeters
The final sum is 10,420 meters.
To solve the mathematical problem of adding different units of measurement, we first need to convert everything to the same unit. In this case, let's convert all measurements to meters (m).
Convert 8 kilometers (km) to meters. Since 1 km = 1000 m => 8 km = 8 x 1000 => 8000 m.Convert 2300 meters (m) to meters. This is already in meters, so no conversion is needed and it remains 2300 m.Convert 12,000 centimeters (cm) to meters. Since 1 m = 100 cm, 12,000 cm = 12,000 / 100 = 120 m.Now, add these values together:
8000 m + 2300 m + 120 m = 10,420 meters

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of variation
To find k use the condition y = 2 when x = 4
k = yx² = 2 × 4² = 2 × 16 = 32, thus
y = [tex]\frac{32}{x^2}[/tex] ← equation of variation

The volume of a cylinder, V(h), is given by the area of the base times the height, h. The base of the cylinder shown below has a diameter of 5 inches.
Part A: Write the function, V(h), that represents the volume of the cylinder
Part B: find V(3) and tell what it represents
Answer:
Part a) [tex]V(h)=6.25\pi h\ in^3[/tex]
Part b) [tex]V(3)=18.75\pi\ in^3[/tex] (see the explanation)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
[tex]V=Bh[/tex]
where
B is the area of the base of cylinder
h is the height of the cylinder
we have that
[tex]B=\pi r^{2}[/tex]
Part a) Write the function, V(h), that represents the volume of the cylinder
we have
[tex]r=5/2=2.5\ in[/tex] ----> the radius is half the diameter
substitute
[tex]B=\pi (2.5)^{2}[/tex]
[tex]B=6.25\pi\ in^2[/tex]
The volume is
[tex]V(h)=6.25\pi h\ in^3[/tex]
Part b) Find V(3) and tell what it represents
V(3) represent the volume of the cylinder with a height of 3 inches
so
For h=3 in
substitute
[tex]V(3)=6.25\pi(3)\ in^3[/tex]
[tex]V(3)=18.75\pi\ in^3[/tex]
Final answer:
The function for the volume of the cylinder with diameter 5 inches is V(h) = π * (2.5 inches)² * h. To find V(3), we calculate the volume with height 3 inches, which represents the physical volume of the cylinder at that height.
Explanation:
To find the volume of the cylinder, V(h), we must use the formula V = πr²h, where r is the radius of the base, and h is the height of the cylinder.
Part A: Given that the diameter is 5 inches, the radius is half of the diameter, so r = 5 / 2 = 2.5 inches. Thus, the function representing the volume is V(h) = π * (2.5 inches)² * h.
Part B: To find V(3), we substitute h with 3 inches into the function: V(3) = π * (2.5 inches)² * 3 inches. This gives us the volume of the cylinder when the height is 3 inches.

fire work a travels at the speed 300 ft/s firework b travels 240 ft/s. firework b is launched 0.25s before firework a. how many seconds after firework b launches will both fireworks explode?
Answer:
Both fireworks will explode after 1 seconds after firework b launches.
Step-by-step explanation:
Given:
Speed of fire work A= 300 ft/s
Speed of Firework B=240 ft/s
Time before which fire work b is launched =0.25s
To Find:
How many seconds after firework b launches will both fireworks explode=?
Solution:
Let t be the time(seconds) after which both the fireworks explode.
By the time the firework a has been launched, Firework B has been launch 0.25 s, So we can treat them as two separate equation
Firework A= 330(t)
Firework B=240(t)+240(0.25)
Since we need to know the same time after which they explode, we can equate both the equations
330(t) = 240(t)+240(0.25)
300(t)= 240(t)+60
300(t)-240(t)= 60
60(t)=60
[tex]t=\frac{60}{60}[/tex]
t=1
Final answer:
By setting the distance traveled by both fireworks equal, we find that both Firework A and B will explode 1.25 seconds after Firework B is launched.
Explanation:
To solve the problem of when both fireworks will explode, we can use the constant speed equation distance = speed × time. Firework A travels at 300 ft/s, and Firework B travels at 240 ft/s. Firework B is given a 0.25s head start. We need to find the time when they have traveled the same distance.
Let's call the time after Firework B launches when both explode as t. Since Firework A launches 0.25s after B, it will have traveled for t - 0.25s when they explode together. The equations for the distances traveled by both fireworks until that point will be:
Distance Firework A: 300 (t - 0.25)Distance Firework B: 240 tSetting these distances equal to each other:
300 (t - 0.25) = 240 t
Solving for t:
300t - 75 = 240t
60t = 75
t = 1.25s
Therefore, both fireworks will explode 1.25 seconds after Firework B launches.
9. Wade has 126 inches of 1-inch wide bias tape for a border
on a rectangular banner. If the banner needs to be 48
inches long, what is the maximum width it could be?
Answer:
Let 'x' represent the width.
2*48 + 2x = 126
x = 15 in
The maximum width could be 15 inches.
Final answer:
To find the maximum width of the rectangular banner, calculate the total length of bias tape used, subtract it from the available bias tape, and divide the remaining inches by 2. The maximum width of the banner is 15 inches.
Explanation:
Maximum Width Calculation:
Calculate the total length of bias tape used: 48 inches x 2 sides = 96 inches.
Subtract the total length from the available bias tape: 126 - 96 = 30 inches.
Divide the remaining inches by 2 (since there are 2 widths): 30 / 2 = 15 inches.
