Answer:
2 9/10 pans
Step-by-step explanation:
4 2/5-1 1/2=2 9/10 pans
2 and 9/10 pans of lasagna were eaten at the party.
To find out how much lasagna was eaten at the party, you need to calculate the difference between the initial amount of lasagna Margie had and the amount she has left after the party.
Initial amount of lasagna = 4 2/5 pans
Amount left after the party = 1 1/2 pans
First, we need to convert both fractions to a common denominator. The common denominator of 5 and 2 is 10.
Initial amount of lasagna = 4 x 10/10 + 2/5 x 10/10
= 40/10 + 4/10
= 44/10 pans
Amount left after the party = 1 x 10/10 + 1/2 x 10/10
= 10/10 + 5/10
= 15/10 pans
Now, subtract the amount left after the party from the initial amount to find out how much lasagna was eaten:
Amount eaten = Initial amount - Amount left
Amount eaten = 44/10 - 15/10 = 29/10 pans
You can simplify the fraction further:
Amount eaten = 2 + 9/10 pans
So, 2 and 9/10 pans of lasagna were eaten at the party.

caterpillar crawls 25 inches in one minute. How many inches does it crawl in 5 minutes?
Answer:
125 inches
Step-by-step explanation:
In one minute caterpillar crawls 25 inches. So in 5 minutes we have 5 times 25 inches is 125 inches.
By equation
Additional: 25 + 25 + 25 + 25 + 25 = 125 (inches)
Mutiplication: 25 * 5 = 125 (inches)
The caterpillar crawls 125 inches in 5 minutes
because it is said that the caterpillar crawls 25 inches in one minute so we can use multiplication 25 x 5 = 125
in a class of 7 students there are 4 that play soccer.
if the teacher picks 3 students what is the probability that none of them play soccer
Answer:
Step-by-step explanation:
The total number of ways to draw 3 students is 7*6*5 = 210
Order does not matter. There are 3 students that don't play soccer.
P(3 don't play soccer) = 3*2 * 1 / 210 = 1/35 = 0.02857

Graph the line with slope 2 passing through the point (-5, 2)
Answer:
Equation is y=2x+12
The image is a picture of the graph(it's not the best but it's something.
(1.) Find the equation of the line passing through the points (-4,-6 ) and (-5,5).
(2.) Find the equation of the line with slope -8 that passes through the point (3, -8).
Answer:
1) y=-11x-50 2)y=-8x+16
Step-by-step explanation:
1. y=mx+b- it is the main equation for a line'
If we take the first point and use its coordinates we have -6=-4m+b
If we take the second point and use its coordinates we have 5=5m+b
These equations are simultaneous for our line because the line passes through both points
-6=-4m+b
5=-5m+b
If subtract the second one from the first equation
-6-5= -4m+b- (-5m+b)
-11= m
b= -6-44=-50
y=-11x-50
2) y=mx+b
-8=-8*3+b
b=16
y=-8x+16

Which function below has the following domain and range?
Answer:
The first choice.
Step-by-step explanation:
Domain = x value (first value in a coordinate pair: (x,y))
Range = y value
A function cannot have a repeating Domain value.
This eliminates the last option since -4 is used twice.
The second option has 11 as a y value but it is not in the range.
The third option has 10 as an x value but it is not in the domain.

The second term of arithematic proggresions 7. and the sum of the first four termd is 12 find
a) first term
b)common difference
Answer:
a) a1=15 first term
b) d=-8 common difference
Step-by-step explanation:
1)a1+d=7
2)a1+a2+a3+a4=12
a1+a1+d+a1+2d+a1+3d=12
4a1+6d=12
2a1+3d=6
We have the system of equations where a1+d=7 and 2a1+3d=6
3a1+3d=21
2a1+3d=6
Subtract the second equation from the first one
a1=15
d=-8
First term = 15
Common difference = -8
Let the first term be a and common difference be d.
Therefore,
a+d = 7 - eq. 1
a+(a+d)+(a+2d)+(a+3d) = 12 - eq. 2
4a + 6d = 12
4a + 4d + 2d = 12
Dividing both sides by 2,
2a + 2d + d = 6
2 (a+d) + d = 6
Substituting value of (a+d) in the above equation,
2*7 + d = 6
d = 6 - 14
d = -8
Substuting value of d in eq. 1
a+d = 7
a + (-8) = 7
a = 7 + 8
a = 15

c. What type of business do you own?
d. How many businesses do you own?
For the considered survey, the questions whose response is going to be qualitative is given by: Option C: "What type of business do you own?"
What is qualitative data?
Qualitative data tells about the quality or characteristic. It is tough to express it numerically or not at all expressible numerically. They are usually catagorical.
In contrast, there is quantitative data which can be expressed numerically.
Option A, Option B and Option D will get answers which would be in numbers. Thus, their responses would be quantitative.
Option C's question will get response as type of business that the business owners own. So its not in numbers and tells about the characteristic of businesses.
Thus, for the considered survey, the questions whose response is going to be qualitative is given by: Option C: "What type of business do you own?"

3n-(2+n) what’s the value of n to make the expression equal to 6
Answer:
4
Step-by-step explanation:
3n-(2+n) = 6
3n-2-n = 6
2n-2 = 6
2n = 8
n = 4
Answer:
n=4
Step-by-step explanation:
Start by writing the equation without parenthesis. Since there is a negative sign, everything in the parenthesis changes sign: 3n-2-n=6
Combine like terms: 2n-2=6
move -2 to the other side: 2n=8
divide both sides by 2: n=4

Answer:
[tex]-3(t+1)(8t-3)[/tex]
Step-by-step explanation:
First, factor both the denominators completely:
[tex]9-24t\\= 3(3-8t)\\= 3(-8t+3)\\= -3(8t-3)[/tex]
[tex]8t^2+5t-3\\= 8t^2+8t-3t-3\\= 8t(t+1)-3(t+1)\\= (8t-3)(t+1)[/tex]
Now, we can see that the factors of the first denominator are -3 and 8t-3.
The factors of the second denominator are t+1 and 8t-3.
To find the LCD, multiply all of these factors together:
[tex]-3(t+1)(8t-3)[/tex]
Notice how we only multiply 8t-3 in the equation once. This is because it was present in both denominators, unlike the other factors.

What is an equation of the line that passes through the points (8,-5) and (8, –2)?
Slope Formula (Between 2 points)
[tex] \displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]
Let these be the following:
[tex] \displaystyle \large{(x_1,y_1 )= (8, - 5)} \\ \displaystyle \large{(x_2,y_2 )= (8 ,- 2)} [/tex]
Substitute these points in.
[tex] \displaystyle \large{m = \frac{ - 2 - ( - 5)}{8 - 8} } \\ \displaystyle \large{m = \frac{ - 2 + 5}{0} }[/tex]
Since the denominator is 0. The slope is undefined. However, we can still find the equation of a line but not in y-isolated form.
Since for all y-values give same x-values. This means that the line will always pass at (8,y) where y is set of real numbers.
The line has to be vertical since a x-value can export many y-values.
Hence, the equation of a line would be x = 8
Laura borrowed a total of $21,000 from two different banks to start a business. One bank charged the equivalent of 5% simple interest, and the other charged

Let x represent the principal on the business loan at 5%.
Then, (ID is
he
remaining amount borrowed at 6.5%
X
The amount borrowed from the first and second bank is 19000 and 2000 respectively.
Recall :
Simple interest = P×R×T
Total principal, P = 21000
Bank 1 :
Let, Principal, P = x
Rate, R = 5%
Time, T = 3
Bank 2 :
Principal, P = (21000 - x)
Rate, R = 6.5%
Time, T = 3
Total interest paid = 3240
Bank A interest + Bank B interest = total interest paid
[x × 5% × 3] + [(21000-x) × 6.5% × 3)] = 3240
0.15x + 4095 - 0.195x = 3240
-0.045x = 3240 - 4095
-0.045x = - 855
x = 19000
Hence,
19000 was borrowed from Bank 1
(21000 - 19000) = 2000 was borrowed from bank 2
