What is the inequality for x -3 < 5 (10 points for this question)
answer is x<8
Step-by-step explanation:
The diameter of a human hair is about 0.00067 inches in length. How is this length
expressed in sclentific notation?
A 6.7 x 10 4in.
B 67 x 10 4 In.
C 6.7 x 10-4 in.
D 67 x 10-4 in.
Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.
Help me with this for brainiest
Answer:
11) 2 x 3.14 x (19/2) > (we want to use the radius)
2 x 3.14 x 9.5 = 59.66
12) 2 x 3.14 x (11/2) > (we want to use the radius)
2 x 3.14 x 5.5 = 34.54
34.54/2 + 11 = 28.27 >(becuase it is only a semicircle)
the plus 11 is the diameter, because the cirlce is cut in half

11 5(2x + 1) + c(x + d) = 12x - 1
Work out the value of c and the value of d.
Answer:
c = 2, d = - 3
Step-by-step explanation:
Expand and simplify the left side then compare the coefficients of like terms on both sides.
5(2x + 1) + c(x + d) ← distribute parenthesis
10x + 5 + cx + cd
= x(10 + c) + 5 + cd
Compare like terms on both sides, that is
10 + c = 12 ( subtract 10 from both sides )
c = 2
Then
5 + cd = 5 + 2d and
5 + 2d = - 1 ( subtract 5 from both sides )
2d = - 6 ( divide both sides by 2 )
d = - 3
A box contains 5 red, 4 white and 6 blue balls. If three balls are drawn at random without replacement, determine the probability that none of the balls selected is red.
Answer:
The probability that none of the balls selected is red ²⁴/₉₁
Step-by-step explanation:
Given;
number of red balls, R = 5
number of white balls, W = 4
number of blue balls, B = 6
Total number of balls, = 5 + 4 + 6 = 15
Probability of selecting 3 none red balls = P(WWW) or P(BBB) or P(WWB) or P(WBW) or P(BWW) or P(BBW) or P(BWB) or P(WBB)
[tex]P = (\frac{4}{15} \times \frac{3}{14} \times \frac{2}{13} ) + (\frac{6}{15} \times \frac{5}{14} \times \frac{4}{13} ) + (\frac{4}{15} \times \frac{3}{14} \times \frac{6}{13} ) + (\frac{4}{15} \times \frac{6}{14} \times \frac{3}{13} ) + \\\\(\frac{6}{15} \times \frac{4}{14} \times \frac{3}{13} ) + (\frac{6}{15} \times \frac{5}{14} \times \frac{4}{13} ) + (\frac{6}{15} \times \frac{4}{14} \times \frac{5}{13} ) + (\frac{4}{15} \times \frac{6}{14} \times \frac{5}{13} )[/tex]
[tex]P = \frac{24}{2730} + \frac{120}{2730} + \frac{72}{2730} +\frac{72}{2730} + \frac{72}{2730} + \frac{120}{2730} + \frac{120}{2730} + \frac{120}{2730} \\\\P = \frac{720}{2730} \\\\P = \frac{24}{91} \\\\[/tex]
Therefore, the probability that none of the balls selected is red ²⁴/₉₁

288 ft2
160 ft2
136 ft2
264 ft2
Answer:
136 ft^2
Step-by-step explanation:

Let point A be [tex] (x_{1}, y_{1}) [/tex], and let point B be [tex] (x_{2}, y_{2}) [/tex].

The equation of a circle centered at the orgin is x^2 + y^2 = 16. What is the radius of the circle
Given:
The equation of the circle is:
[tex]x^2+y^2=16[/tex]
To find:
The radius of the circle.
Solution:
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is the center and r is the radius.
We have,
[tex]x^2+y^2=16[/tex]
In can be written as:
[tex]x^2+y^2=4^2[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]h=0[/tex]
[tex]k=0[/tex]
[tex]r=4[/tex]
Here, the center of the circle is the origin and the radius is equal to 4 units.
Therefore, the radius of the given circle is 4 units.

Answer:
so it is more than 1 quart, but less than 1.5 quarts, so narrow down the answer choices
1. w could be 3/4? no. 3/4 is less than 1
2. w could be 1. no. the bottle contains more than 1 quart.
3. w>1 it could be, but it dosent specify what w is, so we have no way of knowing if its over or under 1.5
4. w could be 4/3. yes that works. in mixed form it would be 1 and 1/3, it is more than one, but less than 1.5
5. w could be 5/3 no. 5 over 3 in mixed forn is 1 and 2/3, witch is over 1.5
6. w>1.5 nope. it cant be over 1.5
THE ANSWER IS THE 4TH ANSWER. W COULD BE 4/3

The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.

Find all solutions of the equation in the interval [0, 2pi)
cosx (2 sinx+1)=0
Answer:
x = pi/2 and 11pi/6
Step-by-step explanation:
Given the trigonometry expression
cosx (2 sinx+1)=0
This can be written in two forms as;
cosx = 0 and 2sinx + 1 = 0
If cos x = 0
x = arccos0
x = 90degrees
x = pi/2
Similarly
2sinx + 1 = 0
2sinx = -1
sinx = -1/2
sinx =-0.5
x = aarcsin(-0.5)
x = -30
Since sin is negative in the third and 4th quadrant
x = 270 + 30
x = 330degrees
x = 330pi/180
x = 11pi/6
Find the value of sin^-1(4pi/5)
Answer:
No value because 4π/5 exceeds the domain
Step-by-step explanation:
The domain and range of sin^-1(x) is a domain of [-1,1] and a range of [-π/2,π/2]
Since 4π/5>1, this exceeds the domain and therefore has no value.

Each color is a

Answer:
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
Step-by-step explanation:
P.S - The exact question -
Given - The diagram
To find - The number that represent Red, Silver and Blue color.
Proof -
Let the number printed in red color = r
Let the number printed in silver color = s
Let the number printed in blue color = b
Also,
Given that the equation is -
b s r
b s r
+ b s r
= r r r
Now,
We have to think of a number that if we add the last digit of the number gives the same last digit.
Bt inspection ,
the number would be 5
Because 5 + 5 + 5 = 15
Lat place of the equation is same
So,
The number printed on red color = 5
⇒r = 5
So, the equation becomes
b s 5
b s 5
+ b s 5
= 5 5 5
Now,
We have to think of a number whose last digit add up to 3 + 1 gives the last digit number 5 ( we add 1 because by adding 5 + 5 + 5 , we get 15 so we write the last digit 5 and 1 goes to the remainder and that remainder 1 will add up in the next number addition)(addition rule)
i.e.
s + s + s + 1 = number whose end digit is 5
By inspection,
The number would be 8
because 8 + 8 + 8 + 1 = 25
So,
we get
s = 8
So, the equation becomes
b 8 5
b 8 5
+ b 8 5
= 5 5 5
Now,
By same process , we will find the number of blue color
By inspection the number on blue color = 1
∴ we get
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
and the equation is -
1 8 5
1 8 5
+ 1 8 5
= 5 5 5
1). What are the vertices of the hyperbola whose equation is:
( y + 6 ) ² ( x + 8 ) ²
_____ - _____
81 49
2). What are the foci of the hyperbola whose equation is:
( x - 6 ) ² ( y + 7 ) ²
_____ - _____
16 9
Answer:
1) The vertices of the hyperbola are (-8, -15), (-8, 3)
2) The foci of the hyperbola are (11, -7) or (1, -7)
Step-by-step explanation:
1) The vertices of a hyperbola given in the form [tex]\dfrac{\left (y - k\right)^2}{a^2} -\dfrac{\left (x - h\right)^2}{b^2} = 1[/tex] is (h, k ± a)
Therefore, for the given hyperbola with the following equation;
[tex]\dfrac{\left (y + 6\right)^2}{81} -\dfrac{\left (x + 8\right)^2}{49} = 1[/tex], we have;
[tex]\dfrac{\left (y + 6\right)^2}{9^2} -\dfrac{\left (x + 8\right)^2}{7^2} = 1[/tex]
Therefore the vertices are;
(-8, -6 ± 9) = (-8, -15), (-8, 3)
2) The equation of the given hyperbola is presented as follows;
[tex]\dfrac{\left (x - 6\right)^2}{16} -\dfrac{\left (y + 7\right)^2}{9} = 1[/tex]
The given hyperbola is of the form;
[tex]\dfrac{\left (x - h\right)^2}{a^2} -\dfrac{\left (y - k\right)^2}{b^2} = 1[/tex]
We get;
[tex]\dfrac{\left (x - 6\right)^2}{4^2} -\dfrac{\left (y + 7\right)^2}{3^2} = 1[/tex]
The foci is then (h ± c, k)
Therefore, by comparison, the foci of the given hyperbola is (6 ± c, -7)
Where c² = a² + b²
∴ c² = 4² + 3² = 25
c = √25 = 5
∴ The foci; (6 ± 5, -7) = (11, -7) or (1, -7).
