Note: This question needs practical measurements so I am going to use my clock at home. Otherwise, you can measure the clock at your house and work out.
the diameter of the clock= 30 cm
the radius of the clock= 15 cm
(a) the area of the clock is
[tex]\pi r^{2} = 3.14 \times 15^{2} = 706.5 \: cm^{2} [/tex]
(b) The length of the minute hand covered in one hour is equal to the circumference of the clock.
The circumference of the clock is
[tex]2\pi \times radius = 2 \times 3.14 \times 15 = 94.2 \: cm[/tex]

What is the slope of the line that passes through the points (25, 50) and (80, 110)?
PLs HELP I WILL DO ANYTHING
Answer:
12/11
Step-by-step explanation:
the formula to find the slope of a line is:
where is the slope and and are the points where the line passes.
in this case we have that the first point is: (25,50) thus⇒ and
and the second point: (80,110) thus ⇒ and
substituting this values into the formula for the slope:
the slope of the line is 12/11

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
Answer:
14.76 cm
Step-by-step explanation:
Use the pythagorean theorem:
a² + b² = c²
Plug in the side lengths and solve for c:
7² + 13² = c²
49 + 169 = c²
218 = c²
14.76 = c
So, the hypotenuse is approximately 14.76 cm

Help pls !!!! Math is fun
Answer:
16
Step-by-step explanation:
The ratio fo the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
In a 30-60-90 triangle, the length of the short leg is the length of the long leg divided by sqrt(3).
The length of the short leg is 8 cm.
The length of the hypotenuse is twice the length of the short leg.
g = 2 * 8 cm = 16 cm
An ice cream shop sells 700 cones per day at a price of $4.50. A survey lets the owner know
that for every decrease in price of $0.50, they will be able to sell 100 extra cones. Write an
equation for the Revenue, R, which can be used to determine how much the owners should
charge in order to maximize their revenue.
Answer:
R(x) = (4.50 – 0.50x)(700 + 100x)
___________________________
R(x) is in factored form
Where x is each decrease in the price.
____________________________
Explanation:
R(x) is in the form ax² + bx + c.
This is where the equation is distributed and simplified [Standard form]
The maximum revenue is represented by
R(-b/2a), where the vertex of this relationship is, at x = -b/2a.
Revenue = (Price)(Quantity)
____________________________
R(x) = (4.50 – 0.50x)(700 + 100x) →
-50x² + 100x + 3150 [ax² + bx + c].
x = -b/2a
x = -(100)/2(-50)
x = -100 / -100
x = 100 / 100
x = 1
Therefore R(1) or where the price is decreased by a factor of 1 is the maximum revenue.
R(2) = -50(1)² + 100(1) + 3150
R(2) = -50(1) + 100 + 3150
R(2) = -50 + 100 + 3150
R(2) = 3200.
_______________________________
Thus the best revenue ($3,200) is obtained by decreasing the price once (Price of 4$), with 800 cones.
whats the area of this figure
Answer:
341km2
Step-by-step explanation:
7km*25km=175km2
8km*(11km+6km)=136km2
5km*6km=30km2
175km2+136km2+30km2=341km2
What are the answers to all the questions? Make sure to show your work and the check.
1. 34c = 68
Divide both sides by 34
C = 68/34
C = 2
2. D - 1/2 = 3/4
Add 1/2 to both sides
D = 3/4 + 1/2
D = 1 1/4
3. E + 52.5 = 81
Subtract 52.5 from both sides
E =81-52.5
E = 28.5
4. 18 = f/0.3
Multiply both sides by 0.3
F = 18 x 0.3
F = 5.4
The combined area of a square and a rectangle is 33 square meters. The width of the rectangle is 1 meter more than the length of one side of the square and the length of the rectangle is 3 meters more
than its width.
a) Calculate the dimensions of the rectangle and its perimeter
b) Calculate the dimensions of the square.
Answer:
Step-by-step explanation:
Square is x meters on each side.
Area of square = x²
Width of rectangle = x+1
Length of rectangle = x+4
Area of rectangle = (x+1)(x+4) = x²+5x+4
Combined area = 2x²+5x+4 = 33
2x²+5x-29 = 0
x = [-5+√(5²-4(2)(-29))]/[2(2)] = [-5 +√257]/4
what valie of x makes the equation true
Answer:
x = 1.25
Step-by-step explanation:
-3x+10 = 5x-8
+3x +3x
10 = 8x - 8
+8 +8
18 = 8x
x = 18/8
x = 1 1/4 = 1.25

Step-by-step explanation:
Tom spent half of his allowance going to the movies. He washed the family car and earned 7 dollars. What is his weekly allowance if he ended with 15 dollars?
Answer:
Tom's weekly allowance is $16.
Step-by-step explanation:
With the information provided, first you have to subtract the amount he earned washing the family car from the total amount he had to determine the amount he had left from his allowance after going to the movies:
$15-$7=$8
Now, since the statement indicates that tom spent half of his allowance going to the movies, this means that the $8 represents the amount left after going to the movies and it is half of his allowance. So, you have to multiply this amount by 2 to find his weekly allowance:
$8*2=$16
According to this,the answer is that Tom's weekly allowance is $16.
Solve for x solve for x
Answer:
15
Step-by-step explanation:
The sum of angles around a point is added up to 360°.
Accordingly,
4x - 2 + 9x + 6 + 8x - 5 + 46 = 360
Combine like terms.
21x + 45 = 360
Subtract 45 from both sides.
21x = 360 - 45
21x = 315
x = 15

[AB] is a diameter of center C(O, 3cm). M is a point on (C) such that MA=MB. D is the symmetric of A with respect to M.
What is the nature of triangle AMB? Justify.
Answer:
Isosceles right triangle.
Step-by-step explanation:
From the given triangle ABM,
AM ≅ MB [Given]
∠AMB is an angle subtended by the diameter AB.
By theorem, angle subtended by a diameter is always 90°.
m∠AMB = 90°
So the given triangle is a right triangle with two equal sides AM and MB.
Therefore, ΔAMB is an isosceles right triangle.

Apply the distributive property to create an equivalent expression. 1/2 ( 10 x + 20 y + 10 z )=
Answer:
5x+10y+5z
Step-by-step explanation:
Distributive Property means you multiply each component by the value you are distributing in this case: (1/2)(10x) + (1/2)(20y) + (1/2)(10z) which will yield 5x+10y+5z
Students took a poll that asked whether or not they watch television in the evenings and whether or not they have homework on those same evenings. The two-way table below shows the results of the poll.
Homework No Homework Total
TV 6 12 18
No TV 9 3 12
Total 15 15 30
Calculate the relative frequency of the data to determine which association the two-way table suggests.
A.
Students who watch television in the evenings tend to have homework.
B.
None of the associations listed are correct.
C.
Students who watch television in the evenings tend not to have any homework.
D.
Students who do not watch television in the evenings tend not to have any homework.
Answer:
Students who watch television in the evenings tend not to have any homework is the association suggested by the two-way table.
Step-by-step explanation:
Of the students who watch television, 33% have homework, and 67% do not have homework.
So, students who watch television in the evening tend not to have homework.
Of the students who do not watch television, 75% have homework, and 25% do not have homework.
So, students who do not watch television in the evenings tend to have homework.

Find the measure of the angle
Answer:
27
Step-by-step explanation:
The triangle shown is an isoceles triangle. This means that there are two congruent base angles and a vertex angle. In this case, angle X and angle Y are the base angles, so we can set up an equation to first find the value of t.
5t - 13 = 3t + 3
2t - 13 = 3 (Subtract 3t from both sides)
2t = 16 (Add 13 to both sides)
t = 8 (Divide both sides by 2)
Now that we have the value of t, we can plug it back in to the expression for angle X to find its measure.
5(8) - 13
40 - 13
27
So, the measure of angle X is 27
