How many 7/8 cup servings are in a pitcher that contains 8 1/4 cups of fruit punch?
Answer:
9 and 3/8 left over
Step-by-step explanation:
to calculate this you have to convert the cups to eighths so:
8 cups*8= 64/8
1/4*2= 2/8
64/8+ 2/8= 66/8
66 divided by 7= 9 and 3/8

If the equality symbol of an equation is changed to an inequality symbol that does not includes equal to,
why is the solution to the equation always not included in the solution to the inequality?
The solution to the equation always not included in the solution to the inequality
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Two or more expressions with an Equal sign is called as Equation.
Where as a relationship between two expressions or values that are not equal to each other is called 'inequality.
Both inequality and equations are different,
Inequalities and equations are both math statements that compare two values.
Equations use the symbol =

In the morning a group of hikers hiked 3 ½ miles, took a break, and then hiked another 2 ¾ miles. The group then stopped for lunch. In the afternoon, the group the hiked 4 ¼ miles, and took another break. How many more miles do they need if the whole trail is 14 miles long?
Answer:
3 2/4
Step-by-step explanation:
1/2 is equivalent to 2/4 so you add 3 2/4 + 2 3/4 and that = 6 1/4 and its simple math from there on, 6 1/4 + 4 1/4 = 10 2/4 finally 14 - 10 2/4 = 3 2/4

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
In the morning a group of hikers hiked 3 ½ miles
and then hiked another 2 ¾ miles. then group the hiked 4 ¼ miles.
Total miles to cover = 14 miles
So, number of miles to be driven
= 14 - ( 3 ½ + 2 ¾ + 4 ¼)
= 14 - ( 7/2 + 11/4 + 17/4)
= 14- (14/4 + 11/4 + 17/4)
= 64 - 42 / 4
= 22/4= 11/2
= 5.5 miles
Hence, 5.5 miles are left to cover.

Barbra has a part-time lawn-mowing job. The table below shows the amount of money Barbra earned for different numbers of hours of work: Barbaras earnings from lawn mowing number of hours worked money earned (dollars) 5 40 6 48 56 part A: what are the missing numbers in the table? Show your work. (4 points) part b. Barbara also works Part time at a theme park. To the money she earns so 1:9.create a table to show the money earned by Barbara for 5,6 and 8 hours of work at the theme park (3 points) PartC: how many more dollars does Barbara ern working fat the theme park for 5 hours then mowing lawns for 5 hours? Show your work
Answer:
it isn't obvious from your problem statement where the missing numbers are in your table. We have assumed that Barbara charges the same hourly rate for all mowing jobs, so the red numbers were the ones that were missing.
Since we know our times-8 and times-9 times tables, all the work is mental. There is nothing to show. Each number in the Dollars column is 8 times the number in the Hours column.
B) See the table on the right. Again, we know our times tables. 5*9 = 45, and so on.
C) 45 -40 = 5
Barbara earns 5 dollars more at the theme park for 5 hours' work than she does mowing lawns. (Check: The rate difference is $1 per hour, so the difference in earnings will be $5 for 5 hours.)

if the area of a right isosceles triangle is 128 sq . m, what will be length of the identical side of the triangle
Let's see. What is a right isosceles triangle?
A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.
What is the formula for the area of an isosceles triangle?
When y = the identical side lengths of the triangle,
and A = area,
(y × y) ÷ 2 = A
Note: Remember to compute from left to right! :)
We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.
Now, we can plug-in our values!
(y × y) ÷ 2 = 128
(y × y) = 64
Now, we square root both sides!
y = √64
y = 8
The length of the identical sides of the triangle is 8 meters.
[tex]\large\underline{\underline{\red{\sf \blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]
Given that area of an isosceles triangle is 128m² .
And the triangle is right Angled ∆ .
So , the measure of sides along 90° that is perpendicular and the base will be equal .
Let us say that each of the equal sides is x .
Then , we can find the area of the triangle as ,
[tex]\boxed{\bf{\red{ Area_{triangle}=\dfrac{1}{2}\times(base)\times(height)}}}[/tex]
Now , here substitute the respective values ,
[tex]\implies \sf \dfrac{1}{2}\times(base)\times(height)=128m^2[/tex]
[tex]\sf\implies \dfrac{1}{2}\times x \times x = 128m^2[/tex]
[tex]\sf \implies \dfrac{x^2}{2}=128m^2[/tex]
[tex]\sf\implies x^2=128\times2 m^2[/tex]
[tex]\sf\implies x^2=256 m^2[/tex]
[tex]\sf\implies x=\sqrt{256m^2}[/tex]
[tex]\underline{\boxed{\red{\sf\longmapsto x=16m}}}[/tex]
Hence the value of value of identical side of the triangle is 16m .
y=t+a/t-b
express t in terms of a, b and y.
t-b
Answer:
t=(a+by)/(y-1)
Step-by-step explanation:
(t-b)y =t+a
ty-by = t+a
ty-by=t+a
ty-by=a+by
t(y-1)=a+by
thus,
t=(a+by)/(y-1)
What is the equation of the line that passes through the points (-6,-7) and (6,3)
Answer:
[tex]y=\frac{5}{6} x-2[/tex]
Step-by-step explanation:
Point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]where [tex](x_1, \ y_1)[/tex] are coordinates of a point that the line passes through, and [tex]m[/tex] is the slope of the line.
We are given two points that the line passes through, but we are not given the slope.
We can find the slope by using the slope formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]where [tex](x_1, \ x_2)[/tex] and [tex](y_1, \ y_2)[/tex] are two points that the line passes through.
Substitute (-6, -7) and (6, 3) into the slope formula:
[tex]\frac{3-(-7)}{6-(-6)} = \frac{10}{12} = \frac{5}{6}[/tex]The slope of this line is 5/6. Now we are able to use the point-slope equation to find the slope-intercept equation [tex](y=mx+b)[/tex] of this line.
Substitute a point that the line passes through and the slope of the line into the point-slope equation. I'm using the point (6, 3).
[tex]y-y_1=m(x-x_1)[/tex][tex]y-(3)=\frac{5}{6} (x-(6)[/tex][tex]y-3=\frac{5}{6} (x-6)[/tex]Distribute 5/6 inside the parentheses.
[tex]y-3=\frac{5}{6} x-\frac{30}{6}[/tex][tex]y-3=\frac{5}{6} x-5[/tex]Add 3 to both sides of the equation.
[tex]y=\frac{5}{6} x-2[/tex]This is the equation of the line that passes through (-6, -7) and (6, 3) in slope-intercept form.

The opposite of 45 is equal to the absolute value of −45.
The opposite of −45 is not equal to the absolute value of 45.
The opposite of 45 is equal to the absolute value of 45.
Answer:
The opposite of 45 is equal to the absolute value of -45.
Absolute value means switching to to a negative if it's a positive and if it's a negative to a positive. For 0, it remains 0 and doesn't switch to a -/+.
