Answer:
The sign on the end result is +
Step-by-step explanation:
Given
[tex]-4*(-8/9)*2.78*(1\ 1/3)*(-2/5)*(-6.2)*(0.2873)*(3\ 1/11)[/tex]
Required
Determine the sign of the result
To do this, we simply write out the product of the sign of individual digit.
[tex]-4*(-8/9)*2.78*(1\ 1/3)*(-2/5)*(-6.2)*(0.2873)*(3\ 1/11)[/tex] becomes
[tex]- * - * + * + * - * -* + * +[/tex]
Group the product in 2's
[tex](- * -) *( + * +) *( - * -)* (+ * +)[/tex]
As a general rule:
[tex]- * - = +[/tex]
[tex]- * + = -[/tex]
[tex]+ * - = -[/tex]
[tex]+ * + = +[/tex]
Apply this rule on the above;
[tex](- * -) *( + * +) *( - * -)* (+ * +)[/tex] becomes
[tex]+ * + * + * +[/tex]
Group in 2's
[tex](+ * +) * (+ * +)[/tex]
Apply the rule
[tex]+ * +[/tex]
Finally, this gives:
[tex]+[/tex]
Hence, the sign on the end result is +

A local charity receives 13of a fundraiser during a craft fair and a bake sale. The total amount given to charity was $137.45. How much did the bake sale raise?
Complete question :
A local Charity receives 1/3 of funds raised during a craft fair and bake sale. The total amount given to the charity was $137.45. How much did the bake sale raise
Answer:
$412.35
Step-by-step explanation:
Given that:
Fraction Given to charity from bake sale = 1/3 of amount raised
Amount given to charity = $137.45
Let amount raised from bake sale = x
Hence,
1/3 of x = 137.45
x / 3 = 137.45
x = 137.45 * 3
x = $412.35
Amount raised from bake sale = $412.35

u = 4i + 9j
8= -8j
Find: u +g
Answer:
4i + j
Step-by-step explanation:
I think you meant g instead of 8.
Given:
u = 4i + 9j
g = -8j
u + g
(4i + 9j) + (-8j)
4i + j
A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers, with the same combination of sixth- and seventh-grade students in each group. She wants to form as many groups as possible. If the largest group was formed, how many students of each grade level would be in each group?
Answer:
The music director can form a total of 15 groups
6 Sixth grade students per group
5 Seventh grade students per group
Step-by-step explanation:
Sixth grade students = 90
Seventh grade students = 75
Find the highest common factor of 75 and 90
90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.
75 = 1, 3, 5, 15, 25, 75
The highest common factor of 75 and 90 is 15
Therefore, the music director can form a total of 15 groups
Sixth grade students per group = 90 / 15
= 6 Sixth grade students per group
Seventh grade students per group = 75 / 15
= 5 Seventh grade students per group

Answer:
So, lets say the refridgerator started at 37 degrees F alright?
Step-by-step explanation:
37 - 4 = 33
33 + 2 = 35
35 - 7 = 28
28 - 1 = 27
27 + 3 = 30
30 + 1 = 31
So the final temurature at 2:00pm would be 31 degrees F

Assume you know that a hot-air balloon is currently inflated with a certain amount of air and that the amount is a percent of the total amount required to inflate the balloon. Explain how you would determine the total amount of air required to inflate the balloon.
Answer:
Percent air is calculated as:
Percent air = Current amount/Total amount *100Solve for total amount of air:
Total amount = Current amount / Percent air * 100Substitute the values in hand to get the answer
use the function y=3/2x+3 to complete the table of values
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
Putting all the values of y=9, 6, 0, and -3 to complete the table
FOR y=9
putting y=9
switch sides
subtract 3 from both sides
Hence,
when y=9, x=4
FOR y=6
putting y=6
switch sides
subtract 3 from both sides
Hence,
when y=6, x=2
FOR y=0
putting y=0
switch sides
subtract 3 from both sides
Hence,
when y=0, x=-2
FOR y=-3
putting y=-3
switch sides
subtract 3 from both sides
Hence,
when y=-3, x=-4
Hence, the table becomes:
x y
9 4
6 2

Sierra's ice cream shop made $45 before she had to close early when the power went out. She realized she lost Two-thirds of a dollar each hour when the shop was closed. The expression that models this situation is 45 minus two-thirds h. What was Sierra's profit if the shop was closed for 6 hours? $24 $36 $41 $49
Answer:
the profit in the case when the shop is closed for 6 hours is $41
Step-by-step explanation:
The computation of the profit in the case when the shop is closed for 6 hours is shown below:
= Expression of the situation × number of hours in which the shop is closed
= 45 - 2 ÷ 3 × 6 hours
= $41
hence, the profit in the case when the shop is closed for 6 hours is $41
Therefore the third option is correct

Slope of line a is ½. What is the equation of a line that is parallel to line a? Y+½x=2 -2x+y+2=0 2x-2=y -½x+y-2=0
Answer:
The equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Step-by-step explanation:
A line is a polynomial function of the first degree that has the following form:
y = m * x + b
where m is the slope of the line and b is the intercept with the Y axis. The slope is the inclination of the line with respect to the abscissa axis.
In this case you know that the slope of line a is ½.
Parallel lines are two or more lines in a plane that never intersect. Two lines are parallel if they have the same slope and different y-intercepts.
You have:
y+½x=2 → y= -½x +2-2x+y+2=0 → y=2x -22x-2=y -½x+y-2=0 → y=½x + 2The line that has the same slope as line a is the last one, so the equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0

Susan can swim 105 meters in 70 seconds. At this rate, how far can she swim in 30 seconds?
Answer:
45 meters per 30 seconds
Step-by-step explanation:
To figure this question out you first gave to find the unit rate of meters per second by dividing 105 by 70.
105 divided by 70 = 1.5
So Susan can swim 1.5 meters per second.
Then we multiply that amount by 30 to find the number of meters she can swim in 30 seconds.
1.5 x 30 = 45 meters
So, in conclusion, Susan can swim 45 meters per 30 seconds

Which equation represents a line which is perpendicular to the line y = 4/3x-6
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.
