Hey there!
3 ÷ 10 is 0.3
So, 0.3 ÷ 6 = x
x = 0.05
Hope this helps! Have a wonderful day!
Answer: 0.05 or [tex]\frac{1}{20}[/tex]
Step-by-step explanation:
We can solve this in 2 ways :
1st Method :
In the first method, we will keep 3/10 as a fraction
[tex]\frac{3}{10}[/tex] ÷ 6
= [tex]\frac{3}{10}[/tex] × [tex]\frac{1}{6}[/tex]
Since 3 and 6 is divisible, we can cancel them
Answer: [tex]\frac{1}{20}[/tex] or 0.05
2nd Method :
3 ÷ 10 =0.3
0.3 ÷ 6
=0.05
A cuboid has a length of 25cm, a width of 5cm and height of (x-2)cm
(a) write an expression, in terms of x, for the volume of the cuboid
(b) the volume of the cuboid is 750cm³.
(i) form an equation in terms of x to represent this information
(ii) solve the equation in (i)
(iii) hence or otherwise calculate the height of the cuboid.
Step-by-step explanation:
Hi there!
From above question;
A cuboid has a length of 25cm, a width of 5cm and height of (x-2)cm.
Length (l) = 25cm
width (b) = 5cm
height (h) = (x-2)cm.
a).
Volume= l*b*h
V = 25*5*(x-2)
V = 125(x-2)
V = 125x - 250 → Answer
b).
(i)
V = 750cm³
V = 125x - 250
750 = 125x - 250..........(i)
(ii)
The equation (i) is: 750 = 125x - 250
or, 125x = 750+250
or, 125x = 1000
or, X = 1000/125
Therefore, X= 8cm.
(iii)
Height (h) = x-2
= 8-2
= 6
Therefore, height is 6cm.
Hope it helps!

Answer:
I'm going to say A and B (I think)
In the right triangle ABC, angle A is 36 degrees.
Answer:
Step-by-step explanation:
The best way to start this question is to find the value of the big 3. The big three (on your calculator) are the sin cos and the tangent. Once you have them, the other three are just the reciprocals.
Sin36 = 0.588
Cos36= 0.809
Tan36 = 0.727
============
Now for the other three, which are not on your calculator (directly)
Csc(36) = 1/sin(36) = 1/0.588 = 1.70
Sec(36) = 1/cos(36) = 1/ 0.809 = 1.236
cot(36) = 1/tan(36) = 1/0.727 = 1.376
I don't know if you remember who marries who here. I always remember that cofunction goes with the non cofunction. So the sin and csc are going out together. The cot and tan are dating etc.

which number best completes the pattern ?
17,12,7
3,7,11
21,16(?)
a. 12 b. 11 c. 8 d. 3
Answer:
11
Step-by-step explanation:
the common difference in the last sequence is 5 which can be gotten by subtracting the first term minus the second term.. therefore to find the next term you subtract 5 from the previous term,and 16-5 is 11.
I hope this helps
Answer:
b
Step-by-step explanation:
The first series has a patten which is an=a(n-1)-5. The second series follow the pattern which is an=a(n-1)+4. The third series follow the pattern an=a(n-1)+5. So 16-5=11.

Answer:
[tex]\displaystyle x = \frac{\pi}{4} , \frac{5\pi}{4}[/tex]
Step-by-step explanation:
We want to find all solutions to the equation:
[tex]\displaystyle \sin 2x - 1 = 0[/tex]
In the interval [0, 2π).
First, add one to both sides:
[tex]\displaystyle \sin 2x = 1[/tex]
Recall that sin(u) equals one whenever u = π/2. This will occur for every rotation. Hence, we can say that u = π/2 + 2nπ where n is an integer.
And in this case, u = 2x. Thus:
[tex]\displaystyle 2x = \frac{\pi}{2} + 2n\pi\text{ where } n\in\mathbb{Z}[/tex]
Dividing both sides by two yields:
[tex]\displaystyle x = \frac{\pi}{4} + n\pi \text{ where } n\in \mathbb{Z}[/tex]
There are two values of x in the interval [0, 2π) given when n = 0 and n = 1:
[tex]\displaystyle x _ 1= \frac{\pi}{4} \text{ and } x_2 = \frac{\pi}{4} + (1)\pi = \frac{5\pi}{4}[/tex]
Any other solutions will be outside our interval.
Therefore, our solutions are:
[tex]\displaystyle x = \frac{\pi}{4} , \frac{5\pi}{4}[/tex]

In a basketball game, Noli scored 3 points by shooting the ball at a horizontal distance of 7 feet from the 10-feet-high hoop. Noli threw the ball 6 feet above the ground and the ball went twice as high as its initial horizontal distance from the hoop. What was the horizontal distance of the ball from Noli when it reached its maximum height?
Answer:
The horizontal distance of the ball from Noli when it reached maximum height is approximately 4.1 feet
Step-by-step explanation:
The horizontal distance from the hoop at which Noli threw the ball, y₀ = 7 feet
The height of the hoop = 10 feet
The height from which the ball was thrown = 6 feet
The height to which the ball is thrown = 2 × The initial horizontal distance from the hoop
∴ The height to which the ball is thrown, [tex]y_{max}[/tex] = 2 × 7 feet = 14 feet
The coordinates of points on the path of the ball are;
(0, 6), (7, 10), (x, 14)
The projectile in vertex form is y = a·(x - h)² + k
Where;
(h, k) = The x, and y-coordinate of the maximum height
The y-coordinate of the maximum height reached = k = 14 feet
The x-coordinate of the maximum height = h = The horizontal distance of the ball from Noli when it reached maximum height
At y = 6, x = 0, therefore, we get;
6 = a·(0 - h)² + 14 = a·h² + 14
6 = a·h² + 14
a = -8/h²
At y = 10, x = 7, we get;
10 = a·(7 - h)² + 14 = (-8/h²)·(7 - h)² + 14
10·h² = -8·(7 - h)² + 14·h²
-4·h² = -8·(7 - h)²
4·h² - 8·(7 - h)² = 0
-4·h² + 112·h - 392 = 0
h = (-112 ± √(112² - 4 × (-4) × (-392)))/(2 × -4)
h ≈ 4.1, or h ≈ 23.9
We reject the value, h ≈ 23.9 feet given that the distance between the where the Noli threw the ball and the hoop = 7 feet
Therefore, the horizontal distance of the ball from Noli at which the ball reached its maximum height, h ≈ 4.1 feet
Help me pls! L need help with this
Answer:
G. -5/2
Step-by-step explanation:
First we want to distribute the 6 into q and 3.
6q + 18 = 2(q + 4)
Next distribute the 2 into q and 4.
6q + 18 = 2q + 8
Now the variable needs to be on one side of the equation. Subtract 2q from both sides.
4q + 18 = 8
Isolate the variable. Subtract 18 from both sides.
4q = -10
Divide 4 on both sides.
q = -10/4
We can now simplify this even further. Divide -10/4 by 2/2
q = -5/2
The question is in the picture

Simplify and find the perimeter of the triangle
Answer:
2x - 19
Step-by-step explanation:
Perimeter = sum of sides
First let's simplify each side
We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.
2(x + 5)
Distribute by multiplying x and 5 by 2
2 * x = 2x and 2 * 5 = 10
2x + 10
1/2(4x + 8)
Distribute by multiplying 4x and 8 by 1/2
1/2 * 4x = 2x and 1/2 * 8 = 4
2x + 4
-3(2x + 11)
Distribute by multiplying 2x and 11 by -3
-3 * 2x = -6x
-3 * -33
-6x - 33
Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )
2x + 10 + 2x + 4 - 6x - 33
Combine like terms
2x + 2x - 6x = -2x
10 + 4 - 33 = -19
Perimeter: -2x - 19
Answer:
Perimeter = - 2x - 19
Step-by-step explanation:
[tex]Perimeter \: of \: a \: triangle \\ = Sum \: of \: the \: length \: of \: all \: sides \\ = [2(x+5)]+[-3(2x+11)]+[ \frac{1}{2} (4x+8)] \\ = [(2 \times x)+(2 \times 5)]+[(-3 \times 2x)+( - 3 \times 11)]+[ (\frac{1}{2} \times 4x) + ( \frac{1}{2} \times 8)] \\ = (2x + 10) + ( - 6x - 33) + (2x + 4) \\ = 2x + 10 - 6x - 33 + 2x + 4 \\ = 2x - 6x + 2x + 10 - 33 + 4 \\ = - 2x - 19[/tex]
So, the perimeter is - 2x - 19.

Answer:

.2776
2.3
1.342
.4129
*note* I had trouble reading the standard deviation of the second part, so if it's not 3 then leave a comment and i will fix it*
Step-by-step explanation:
1.)
the mean would be something like 460*.16= 73.6
The variance should be 460*.16(1-.16)= 61.824 which means the standard deviation is √61.824= 7.863
for p to be less than .15 it would have to be less than .15*460= 69
(69-73.6)/7.863= -.59 which has a probability of .2776
2.)
the mean is 2.3
I am not sure if the standard deviation is 3 or .3 (picture is kind of blurry)
I am thinking that it's three which would mean that the standard deviation would be √(3²*(1/5))= 1.342
(2-2.3)/1.342= -.22 = .4129

The area of the surface of a pool table is 24 square feet. The perimeter is 22 feet. What are the dimensions of the pool table?
Answer: The dimensions are 8 and 3
Step-by-step explanation:
So 8*3=24 which corresponds with the formula for area l*w= Area
And perimeter means we add up all 4 sides so
8+8+3+3= 22
So the dimensions are 8 and 3

Does the graph represent a function? Why or why not?
Answer:
D. Yes, because it passes the vertical line test.
Step-by-step explanation:
In order to be a function, it needs to pass the vertical line test as a function can not have multiple y's for one x. However, functions can have multiple x's for one y such as in a quadratic function.
Answer:
D.
Brainliest, please!
Step-by-step explanation:
This function passes both the horizontal and vertical line tests. But when determining if it is a function or not, the vertical line test is the only one that matters. If we wanted to know if this function had an inverse or not, then B. would be right.
