What is the side length of the smallest square plate on which a 30 cm chopstick can fit along a diagonal without any overhang? The approximate side length of the square plate is black cm.
Answer: 21.21 cm
Step-by-step explanation:
Given
length of diagonal on the square is 30 cm
Suppose a is the side length of the square
and length of diagonal is given as [tex]a\sqrt{2}\ units[/tex]
So,
[tex]\Rightarrow a\sqrt{2}=30\\\\\Rightarrow a=\frac{30}{\sqrt{2}}=21.21\ cm[/tex]
Thus, the side length of the square is 21.21 cm
Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.
Answer:
Step-by-step explanation:
(2,4) is point lying on the line represented by 5x + 2y = 18.
They are not intercepts.
x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.
y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.
5x + 2y = 18
To find x-intercept, put y = 0 in the equation
5x = 18
x = 18/5
x = 3.6
To find y-intercept, put x = 0 in the equation
2y = 18
y = 18/2
y = 9
x-intercept : (3.6 , 0)
y-intercept :(0, 9)
30=-6x+6
Solve the equation
Answer:
-4
Step-by-step explanation:
24 = -6x
-4 = x
............
Answer:
x = -4
Step-by-step explanation:
30 = - 6x + 6
- 6x = 30 - 6
- 6x = 24
- x = 24 / 6
- x = 4
x = - 4

What is the value of y in the parallelogram below?
5y"
654
O A. 110
O B. 60
O c. 13
D. 23
Answer:
D. 23
Step-by-step explanation:
5y = [360 - (65 x 2)] / 2
5y = [360 - 130] / 2
5y = 230 / 2
5y = 115
y = 23

What two numbers when multiplied yield 3 but when added yield the middle coefficient -4?
How about -1 times -3?
Yes, (-1)(-3) is 3 but when added yield -4.
(x - 3)(x - 1) = 0
Set each factor to 0 and solve for x.
x - 3 = 0
x = 3
x - 1 = 0
x = 1

Answer:
180 degrees in either direction
Step-by-step explanation:
picture it on a piece of paper, if you turn it once, the image becomes longer vertically, but if you flip it again, it looks like it does originally. If this is confusing, actually draw it and see how many times you need to rotate the page to make it look identical to the one you posted. 1 turn = 90 degrees.
The length of one diagonal of a rhombus is 8 cm. The area of the rhombus is 72 cm2. What is the length of the other diagonal of the rhombus?
Answer:
18 cm
Step-by-step explanation:
From the question above,
Area of a rhombus
A = d₁d₂/2.................. Equation 1
Where A = area of the rhombus, d₁ = length of one diagonal, d₂ = length of the other diagonal
make d₂ the subject of the equation
d₂ = 2A/d₁............... equation 2
Given: A = 72 cm², d₁ = 8 cm
Substitute these values into equation 2
d₂ = (2×72)/8
d₂ = 144/8
d₂ = 18 cm.

What is the complete factorization of 4x2 − 26x + 30?
2(x + 5)(2x − 3) 2(x − 5)(2x − 3) 2(x − 5)(3x − 2) 2(x + 5)(3x − 2)
Answer:
2( 2x -3)(x- 5)
Step-by-step explanation:
step 1 . factor 2 out ( because when you multiply the 2 again with the equation it will give you the main equation)
2 ( 2x^2 - 13x + 15 )
step 2 . factor now by regrouping
2( 2x- 3 )( x - 5)

Near the equator, the Earth rotates approximately 3 4 kilometers every 3 2 seconds. What is the speed of Earth's rotation near the equator?
Answer:
Speed = 1.0625 km / sec
Step-by-step explanation:
Distance = 34 kilometers
Time = 32 seconds
Speed = ?
The relationship between these quantities is given as;
Speed = Distance / Time
Inserting the values;
Speed = 34 km / 32 sec
Speed = 1.0625 km / sec
Mark works 24 hours a week and earns £11.63.
Calculate Mark's weekly basic pay and then find his annual salary
Weekly pay = amount per hour x number of hours:
24 x 11.63 = 279.12
Annual salary = weekly pay x 52 weeks:
279.12 x 52 = 14,514.24
You are building a doghouse for Fido, your loyal poodle. The blueprint of the doghouse uses a scale of 1 : 14. The floor of the doghouse measures 2" x 2.5" on the blueprint.
Answer:
28" x 35"
Step-by-step explanation:
Based on the ratio we see that for every 1 inch in the blueprint there are a total of 14 inches in the real-life model of the doghouse. Therefore, in order to find the actual dimensions of the real-life doghouse we simply need to multiply the individual length and width dimensions of the blueprint by 14. Since the real-life model is 14 times bigger according to the ratio.
2 * 14 = 28
2.5 * 14 = 35
Finally, we can see that the real-life doghouse has a the following dimensions 28" x 35"

The relative frequency that the traffic lights will show GREEN at road works is 0.7. Estimate how many times they would be RED over the next 40 journeys?
Answer:
28 reds are expected over the next 40 journeys
Step-by-step explanation:
Here, we want to get the number of reds in the next 40 journeys
From the question, we have that the relative frequency is 0.7
Thus, for the number of reds, we have to multiply the relative frequency by the number of journeys
We have this as;
40 * 0.7 = 28

What is the average rate of change over the interval 1≤x≤3
9514 1404 393
Answer:
3
Step-by-step explanation:
The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-2))/(3 -1) = 6/2
m = 3
The average rate of change on the interval is 3.
