The minute hand of a clock is 6 inches long. How far does the tip of the minute hand move in 15 minutes? How far does it move in 25 minutes?
Answer:
Step-by-step explanation:
angle subtended at center in 15 minutes=360÷60×15=90°=π/4
distance traveled by minute hand=2πr/4=πr/2=6π/2=3π inches≈9.42 inches
distance travelled by minute hand in 25 minutes=2πr×25/60=50πr/60=5/6πr
≈5/6 π×6=5π inches ≈15.71 inches

A company makes 140 bags.
21 of the bags have buttons but no zips.
25 of the bags have zips but no buttons.
45 of the bags have neither zips nor buttons.
How many bags have zips on them?
A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object. The total number of bags that have both zips and buttons is 49.
What is a set?A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that A company makes 140 bags. 21 of the bags have buttons but no zips. 25 of the bags have zips but no buttons. 45 of the bags have neither zips nor buttons.
Now, we can write the following things about the given condition,
Total number of bags, s = 140
Bags with Only zips, only Z = 25
Bags with only buttons, only B = 21
Bags with neither or them, Z'∩B' = 45
Now, the total number of bags that have both of them is,
Z∩B = s - only Z - only B - Z'∩B'
= 140 - 25 - 21 - 45
= 49
Hence, the total number of bags that have both zips and buttons is 49.

) Kadence has $50 in her bank account. Then, she bought a new shirt that cost $33. She then deposited x dollars into her account to bring her balance to $28. What is the value of x?
Answer:
The value of X is $5
Step-by-step explanation:
Step-by-step explanation:
We have $50 - $33 + $x = $28.
=> $17 + $x = $28

The value of x is 11.
a car travels 120 km in one and a half hours. what is the average speed
Answer:
The speed would be 60kph.
Answer:
80 mph (average)
Step-by-step explanation:
Split 120 into thirds, each one being half an hour.
120/3=40
Add two of them together, getting 80.
40x2(or 40+40)=80
Since the car travels 80 miles in one hour, 80 mph is the average speed.

Answer:
the ten-inch side is the hypotenuse.
Step-by-step explanation:
[tex]a^{2}+ b^{2} =c^{2}[/tex]a= 6
b= 8
c= 10
use substitution to replace the variables in the equation, it should look like this:
36+64=100
the equation above is true, so the answer is that the 10-inch side is the hypotenuse.

point (-4,-8) Reflected across the x-axis
Answer:
(-4 , 8)
Step-by-step explanation:
The x-axis is the horizontal line. In this case, if you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.
Same with the y-axis. If you are reflecting over the y-axis, you are flipping the sign of the x-coordinate.
In this case, reflect across the x-axis. Flip the sign of the y: (x , y)
(-4 , -8) reflected over the x-axis is (-4 , 8).

Which model represents 2.36 ÷ 4? A. Three groups of three tenths and four hundredths B. Three groups of five tenths and nine hundredths C. Four groups of three tenths and six hundredths D. Five groups of five tenths and nine hundredths
Answer:
Five groups of five tenths and nine hundredths
Step-by-step explanation:
Mathematically;
2.36 divided by 4 = 0.59
So we want to select from the options, the best representation of this
That will be
0.5 + 0.09
so our answer is 5 groups of five tents and nine hundredths
The model which represents 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths
We must perform the division 2.36 ÷ 4 first so that we have;
2.36 ÷ 4 = 0.59The result, 0.59 can then be written in words as; Five tenths and 9 Hundredths.
Ultimately, the model. which represents the expression 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths.

A rectangular lawn has a diagonal path running across it. The lawn is 10m wide and 15m long. Work out the length of the path
Answer:
d = 18.02 m
Step-by-step explanation:
Given that,
A rectangular lawn has a diagonal path running across it. The lawn is 10m wide and 15m long.
We need to find the length of the path.
The diagonal of a rectangle can be calculated as follows :
[tex]d=\sqrt{10^2+15^2} \\\\d=18.02\ m[/tex]
So, the length of the path is 18.02 m.
Write a quadratic equation given the roots -1/3 and 5, show your work
[tex] \boxed{(x - a)(x - b) = 0}[/tex]
The equation above is the intercept form. Both a-term and b-term are the roots of equation.
[tex]x = - \frac{1}{3} \\ x = 5[/tex]
These are the roots of equation. Therefore we substitute a = - 1/3 and b = 5 in the equation.
[tex](x + \frac{1}{3} )(x - 5) = 0[/tex]
Here we can convert the expression x+1/3 to this.
[tex]x + \frac{1}{3} = 0 \\ 3x + 1 = 0[/tex]
Rewrite the equation.
[tex](3x + 1)(x - 5) = 0[/tex]
Simplify by multiplying both expressions.
[tex]3 {x}^{2} - 15x + x - 5 = 0 \\ 3 {x}^{2} - 14x - 5 = 0[/tex]
Answer Check
Substitute the given roots in the equation.
[tex]3 {(5)}^{2} - 14(5) - 5 = 0 \\ 75 - 70 - 5 = 0 \\ 75 - 75 = 0 \\ 0 = 0[/tex]
[tex]3( - \frac{1}{3} )^{2} - 14( - \frac{1}{3}) - 5 = 0 \\ 3( \frac{1}{9} ) + \frac{14}{3} - 5 = 0 \\ \frac{1}{3} + \frac{14}{3} - \frac{15}{3} = 0 \\ \frac{15}{3} - \frac{15}{3} = 0 \\ 0 = 0[/tex]
The equation is true for both roots.
