Answer:
You have to take 15 pens to get at least one red pencil.
Step-by-step explanation:
If there were one red and 6 green pens, there would be more red than green pens.
If there were 3 or more blue and thus 18 or more green pens, the number of pens would be over 20.
So there must be 2 blue, 12 green and thus 6 red pencils. So you have to take at least 15 pens to be sure that you got a red one.
This is a math question. Solve for x - 5x = 15?
Answer:
x = -3.75
Step-by-step explanation:
First, combine like terms:
x - 5x = -4x
-4x = 15
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide -4 from both sides:
(-4x)/-4 = (15)/-4
x = 15/-4
x = -3.75
-3.75 is your answer for x.

Answer:
x = -15/4
Step-by-step explanation:
x - 5x = 15
Combine like terms
-4x = 15
Divide each side by -4
-4x/-4 = 15/-4
x = -15/4
BRAINLIEST!! THANKS! How many numbers less than 1000 are there that use only the digits of 2088?
Answer:
The answer is 17
Step by Step explanation:
The one-digit numbers are: 2, 0 and 8
The two-digits number are: 20, 28, 80, 82 and 88
The three-digits number are: 208, 280, 288, 808, 880, 802, 882, 828 and 820
So if you add all the numbers up, it is 17 since the one-digit numbers contain totally 3 numbers, the two-digit numbers contain 5 numbers and the three-digit numbers contain 9 numbers.
which is the equation of a line that is perpendicular to the line represented by y=3/4x-1/2?
Find the slope of the line. m=
Answer:
the slope is 0
m= 0
Step-by-step explanation:
whenever a line is horizontal and straight across the plane the slope is 0
Answer:
m = 0
Step-by-step explanation:
slope can be found using the following equation:
m (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-3 , -2)
(x₂ , y₂) = (1 , -2)
Plug in the corresponding numbers to the corresponding variables:
m = (y₂ - y₁)/(x₂ - x₁) = (-2 - (-2))/(1 - (-3))
Simplify:
m = (-2 - (-2))/(1 - (-3)) = (-2 (+2))/(1 +3) = (-2 + 2)/(1 + 3)
m = (-2 + 2)/(1 + 3) = (0)/(4)
m = 0/4 = 0
The slope of the line is 0.

SOMEONE PLEASEEEEE HELLPPP !! The diameters of Breaburn apples are normally distributed with a mean of 8.2cm and a standard deviation of 2.8cm. If you had a shipment of 2000 apples, how many apples would have a diameter: a) smaller than 5.9cm? b) larger than 10.2cm?
Answer:
a. 412
b. 478
Step-by-step explanation:
We have to find the corresponding probabilities using the standard normal table, that is, we must calculate the value of z, the formula of z is as follows:
z = (x - m) / sd
where x is the value to evaluate, m is the mean and sd is the standard deviation.
We are told that the mean is 8.2 cm and the standard deviation is equal to 2.8 cm.
a. smaller than 5.9cm?
In this case x would be 5.9, we replace and we are left with:
z = (x - m) / sd
z = (5.9 - 8.2) /2.8
z = -0.82
If we look for this value in the normal table (attached) it corresponds to 0.2061, to know the number of apples we must multiply this value by the total value of apples, that is 2000. Therefore:
2000 * 0.2061 = 412.2 = 412
b) larger than 10.2cm?
In this case x would be 10.2, we replace and we are left with:
z = (x - m) / sd
z = (10.2 - 8.2) /2.8
z = 0.71
In this case z corresponds to 0.7611, but since this is the value is smaller than 10.2, and we need is larger than 10.2cm, it would be the complement, that is:
1 - 0.7611 = 0.2389
Now to calculate the total number of apples we have:
2000 * 0.2389 = 477.8 = 478
There are several sets of different numbers which can be chosen from {0,1,2,3,4,5,6,7,8,9}. How many of these sets contain any 5 numbers?
Answer:
252 sets
Step-by-step explanation:
The set given to us is:
{0,1,2,3,4,5,6,7,8,9}
Total number of elements in set = n = 10
Number of elements to be included in seach set = r = 5
As the order doesn't matter, we can use the combination formula to find number of different combinations if we choose 5 numbers from the given 10 numbers with no repetition:
C(10,5) = 10!/(5!)(10-5)!
C(10,5) = 10!/(5!)(5!)
C(10,5) = 10·9·8·7·6/ 5·4·3·2·1
C(10,5) = 252
Thus 252 sets can be formed which contains any of the 5 numbers from the sets

Find two consecutive odd whole numbers whose sum is two less than six times the first number.
Answer:
1, 3
Step-by-step explanation:
1st number = x
2nd number = x+2
x+x+2=6x-2
2x+2=6x-2
4=4x
x=1
so the first number is 1 and the second number is 3.
CHECK: The sum of one and three is four, which is two less than six times one.

In which quadrants do solutions for the inequality y is less than or equal to two sevenths times x plus 1 exist?
Answer:
y will be in every single quadrant
Step-by-step explanation:
So we have the equation [tex]y\leq \frac{2}{7} x+1[/tex] first we will have to look at the equation. It says that y is less than or equal to [tex]\frac{2}{7} x+1[/tex] since y is less than [tex]\frac{2}{7} x+1[/tex] the only place the shaded area where y can be is under the line that is drawn be the equation. When the equation is graphed the y-intercept will be on positive 1 it since slope is rise over run it will look something like the file attached to this. so under the line you can see every single quadrant so that is why it would be that way
1/2g=8 pleaseee help
Answer:
g= 16
Step-by-step explanation:
(1/2)*g = 8 to get rid of the 1/2 multiply by 2
g (1/2)*2 = 2*8
1*g = 2*8
g= 16
Answer:
16
1/2g=8
Divide by 1/2 on each side
1/2 = 0.5 because 1 divided by 2 is 0.5
0.5g / 0.5 = g
8 / 0.5 = 16
We are left with
G=16
So G=16

If BD is the angle bisector of ∠ABC, then "∠ABC ≅ ∠ABD + ∠DBC" represents which of the following? Question 12 options: A) Angle addition postulate B) Symmetric property of congruence C) Transitive property of congruence D) Addition property of equality
Answer:
∠ABC ≅ ∠ABD + ∠DBC
Step-by-step explanation:
The angle addition postulate is applied a larger angle is divided into two smaller angles that share the same vertices, the measure of the larger angle is the sum of the two smaller angles. That is the resulting angle formed by two angles which are side by side is the sum of the two angles. In triangle ABC, if ∠ABC is divided by line BD then ∠ABC is divided into ∠ABD and ∠DBC. Therefore:
∠ABC ≅ ∠ABD + ∠DBC

Which angle on a circle graph does 36% represent?
Answer:
There are 360° in a full circle. 36% of 360 = 0.36 * 360 = 129.6° which rounds to 130°.
Answer:
x= 130°
Step-by-step explanation:
We want to khow what is the size of the angle that coresponds 36 percent
we can state :
360 degree ⇒100 percent x (the angle we are looking for)⇒ 36 percent using the proportionality relation : x= (360*36)/100x = 129.6° round it x= 130°Find (f•f)(0)
F(x) = 3x - 2
Answer:
The answer is option C
- 8Step-by-step explanation:
To find ( f•f)(0) first find (f•f)(x)
F(x) = 3x - 2
(f•f)(x) = 3( 3x - 2) - 2
= 9x - 6 - 2
= 9x - 8
( f•f)(0) = 9(0) - 8
= 0 - 8
= - 8

What’s the equation for Property of Zero: 0 divided by 33 =
Answer:
0 / 33 will be 0. Although if it were 33 / 0 then you will get UNDEFINED.
Step-by-step explanation:
You cannot divide anything by zero. This is called the property of zero.
Although, if you divide a number by zero, lets say 33/0, you will get UNDEFINED. You get undefined because zero does not act like a normal number. It is neither positive nor negative.
If f(x) = 1 – x, which value is equivalent to |f(i)|?l
Answer:
Square root ( 2 )
Step-by-step explanation:
We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ).
k=5r-11s solve for r
Answer:
[tex]r=\frac{k+11s}{5}[/tex]
Step-by-step explanation:
[tex]k=5r-11s[/tex]
Add 11s on both sides.
[tex]k+11s=5r-11s+11s[/tex]
[tex]k+11s=5r[/tex]
Divide both sides by 5.
[tex]\frac{k+11s}{5} =\frac{5r}{5}[/tex]
[tex]\frac{k+11s}{5} =r[/tex]
Answer:
11s + k
r = ------------
5
Step-by-step explanation:
k=5r-11s needs to be manipulated so that the 5r term is isolated / alone.
Adding 11s to both sides, we get:
5r = 11s + k
and then dividing all three terms by 5 yields:
11s + k
r = ------------
5
What is the equation of the line that is parallel to the given line and passes through the point (12, −2)? y = –Six-fifths x + 10 y = –Six-fifths x + 12 y = –Five-sixths x – 10 y = Five-sixths x – 12
Answer:
y = Five-sixths x – 12
Step-by-step explanation:
In the picture attached, the given line is shown. Its slope is:
m = [6 - (-4)]/[12 - 0] = 5/6
The line that is parallel to the given line has the same slope.
A line with slope m that pass through (x1, y1) satisfies:
y - y1 = m(x - x1)
Replacing with m = 5/6 and point (12, -2):
y - (-2) = 5/6(x - 12)
y + 2 = 5/6x - 10
y = 5/6x - 10 - 2
y = 5/6x - 12
