To have equal numbers of bowls and cups, Randy should buy 4 packs of bowls and 3 packs of cups, as the least common multiple of 6 (number of bowls per pack) and 8 (number of cups per pack) is 24.
Explanation:If Randy needs an equal number of bowls and cups for his picnic and one pack consists of 6 bowls and another pack consists of 8 cups, the least common multiple (LCM) of 6 and 8 must be found to ensure an equal number of both items. The LCM of 6 and 8 is 24, because 24 is the smallest number that both 6 and 8 can divide evenly into. Therefore, Randy will need to buy 4 packs of bowls (4 packs × 6 bowls per pack = 24 bowls) and 3 packs of cups (3 packs × 8 cups per pack = 24 cups) to have an equal number of each for his picnic.

if the x-intercept (–68, 0), and the y-intercept (0, –34), what is the equation?
y = - [tex]\frac{1}{2}[/tex] x - 34
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 68, 0 ) and (x₂, y₂ ) = (0, - 34 )
m = [tex]\frac{-34-0}{0+68}[/tex] = [tex]\frac{-34}{68}[/tex] = - [tex]\frac{1}{2}[/tex]
the y-intercept = (0, - 34 ) ⇒ c = - 34
y= - [tex]\frac{1}{2}[/tex] x - 34
Answer:
Y=-.5x-34
Step-by-step explanation:
this is because you can do y2-y1/x2-x1 to get slope
-34/68
Which equals one half so currently
Y=-1/2x
To get the y intercept we can look at the number when x=0 so it would be -34. So here is the equation
Y=-.5x-34

The graph of an inequality has a closed circle at 2.6, and the ray moves to the left. What inequality is graphed?
x Greater-than-or-equal-to 12
A closed circle is used on the graph.
The arrow on the graph points right.
The inequality representation is x ≤ 2.6 and has been graphed.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of before example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given,
The graph of inequality has a closed circle at 2.6, and the ray moves to the left.
The closed circle represents that point x = 2.6 is included.
Suppose the variable is x then x ≤ 2.6 represents the inequality.
Hence "The inequality representation is x ≤ 2.6 and has been graphed".

C)f(x)=53x+5

Answer:
B) f(x) = -3/5x +5
Step-by-step explanation:
There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located.
The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.
The slope, the change in y divided by the change in x for two points, is ...
... (-1 -2)/(10 -5) = -3/5
This is the slope and the coefficient of x in the linear equation.
Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:
... y = mx + b
... y = (-3/5)x + 5
Gina is making pancakes for breakfast. Each batch of pancakes calls for 1/4 of a teaspoon of salt. Gina has 9/10 of a teaspoon of salt left. How many batches of pancakes can she make?
Divide the total amount she has by how much she needs per batch.
When dividing fractions, flip the second one over and then multiply straight across.
9/10 / 1/4 becomes: 9/10 x 4/1
9/10 x 4/1 = 36/10 = 3 6/10 = 3 3/5
She can make 3 more batches and have 3/5 of a teaspoon left over.
My friend needed help with this and I found the height through the theorem but can't figure out how to get the base of the overall triangle
You found CD from the Pythagorean theorem to be ...
... CD = √(5² -2²) = √21
Since triangle ADC ~ triangle ACB, the ratios of corresponding sides are the same:
... AC/AD = AB/AC
... AB = AC²/AD
... AB = 5²/2 = 12.5 . . . . . . . the base of the overall triangle
_____
Then the area (A) is ...
... A = (1/2)bh
... A = (1/2)(12.5)(√21) ≈ 28.64 square units
_____
As you see here, the altitude of a right triangle divides it into three similar triangles. From smallest to largest, they are ...
... ADC ~ CDB ~ ACB
You can figure this using AAA similarity, since the smallest and largest triangles listed above share an acute angle vertex (∠A). That, together with the right angle, means all angles are congruent. After that, then you know ∠ACD ≅ ∠CBD, so you can show the middle sized triangle is similar to the other two.

1. y = 3 x
y = -8x
2. y = - 7x
y =-4x - 12
(1)
both equations express y in term of x, hence equate the right sides
- 8x = 3x ( subtract 3x from both sides )
- 11x = 0 ( divide both sides by - 11 )
x = 0
substitute x = 0 into y = 3x → y = 0
solution is : (x, y ) → (0, 0)
(2)
both equations express y in terms of x, hence equate the right sides
- 4x - 12 = - 7x ( add 7x to both sides )
3x - 12 = 0 ( add 12 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into y = - 7x → y = - 28
solution is : (x, y ) = (4, - 28 )

Eva earned the following test scores in science:
82, 100, 96, 90, 91
Ms. Wade entered the next score as 0 because Eva was absent on test day and hadn’t had a chance to make up the test. Which statements are true based on the data? Check all that apply.
After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data.
After adding the 0 test score, the mean would be affected.
After adding the 0 test score, the median would be the most appropriate measure of center to describe the data.
Before the missed test, Eva’s median score was 96.
Before the missed test, Eva’s median score was 91.
Before the missed test, Eva’s mean score was 91.8.
Answer:
The correct answers are "After adding the 0 test score, the mean would be affected.", ad "Before the missed test, Eva’s median score was 91".
Step-by-step explanation:
We know that the mean and median scores would not be helpful in determining Eva's abilities since the 0 is not a representation of how much she knows. However, it will affect the average as adding a 0 to the numerator and a 1 to the denominator will lower the average.
Finally, we can tell the median is 91 before added as when we line up the scores in ascending order, the middle number is 91.
82, 90, 91, 96, 100
Answer:
Statements that are true based on the data:
-After adding the 0 test score, the mean would be affected.
-After adding the 0 test score, the median would be the most appropriate measure of center to describe the data.
-Before the missed test, Eva’s median score was 91.
-Before the missed test, Eva’s mean score was 91.8.
Step-by-step explanation:
-After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data: NO, it won't because the data now has an extreme value that shifts the mean value significantly.
-After adding the 0 test score, the mean would be affected: YES, The mean value would be greatly impacted by adding the 0, (mean=76.5 with the 0; 91.8 without the 0),
-After adding the 0 test score, the median would be the most appropriate measure of center to describe the data: YES, because the median won't be affected as much as the mean by the extreme value.
-Before the missed test, Eva’s median score was 96: NO, the median score was 91 at that point.
-Before the missed test, Eva’s median score was 91: YES, the median score was 91, the median is defined as the value where 50% of sorted values are below and 50% are above
-Before the missed test, Eva’s mean score was 91.8: YES, the mean is defined as the sum of all values divided by the total number of values
The formula for calculating the median is:
-odd number of values: [tex]$ x_m = x_\frac{n+1}{2}[/tex]
-even number of values: [tex]$ x_m = \frac{x_\frac{n}{2}+x_\frac{n+2}{2}}{2}[/tex]
MEDIAN BEFORE ADDING THE 0: 82,90,91,96,100
[tex]$ x_m = x_\frac{5+1}{2}[/tex]=3 (third value)
MEDIAN AFTER ADDING THE 0: 0,82,90,91,96,100,
[tex]$ x_m = \frac{x_\frac{6}{2}+x_\frac{6+2}{2}}{2}[/tex]=average between the 3 and 4 values
[tex]$ x_m = \frac{90+91}{2}[/tex]=90.5

This is 2 seperate triangles
ABC is one triangle and DEF is a different triangle
Answer:
[tex]m\angle c = 30^\circ[/tex]
Step-by-step explanation:
We are given the following information in the question:
ΔABC and ΔDEF
[tex]\angle A \cong \angle D\\\angle B \cong \angle E\\m\angle c = x \\m\angle F = 2x-30[/tex]
According to angle sum property of the triangle the sum of all angles of triangle is equal to 180 degrees.
Since two corresponding angles of the two triangle are equal, therefore the third angle is also equal.
[tex]x = 2x - 30\\\Rightarrow x = 30[/tex]
Thus,
[tex]m\angle c = 30^\circ[/tex]
The measure of the angle from the given information is m∠C = 2x - 30°
How to determine the measure of the angle?Given the information, we have two separate triangles: ABC and DEF.
In triangle ABC, we are given that ∠A ≅ ∠D and ∠B ≅ ∠E.
In triangle DEF, we are given that m∠C = x and m∠F = 2x - 30°.
To find m∠C, we need to find the value of x.
Since ∠A ≅ ∠D, and ∠B ≅ ∠E, we can conclude that triangle ABC is congruent to triangle DEF by the Angle-Angle (AA) congruence criterion.
Using this congruence, we can determine that m∠C = m∠F.
Therefore, we have:
m∠C = m∠F
Since we know that m∠F = 2x - 30°, we can substitute this value into the equation:
m∠C = 2x - 30°
This gives us the measure of angle C in terms of x.
