Answer:
1) (x-2)(x-5)
2) (6r-5)(r+4)
Step-by-step explanation:
1)
It will just be x since the coefficient is 1
To figure out the second number you need to think of the multiples of 10.
So either 2 and 5 or 1 and 10. Since 2 and 5 add to 7 it's them.
They're negative since 7 is and can still make a positive 10.
2)
This one is more just plugging and guessing to see which on works.
Find the multiples of both 6 and 20, afterwards plug in the multiples til you get 19 in the final product.
Since 20 was negative the one of the numbers would be negative.
I can't explain it lol

Step-by-step explanation:
Answer:
23.39
Step-by-step explanation:
To calculate the percentage of underclassmen interested in taking a Mandarin course next year, find the marginal frequency for the total number of underclassmen who showed interest in Mandarin. There are 145 underclassmen who showed interest in Mandarin courses.
Find the total number of underclassmen who were polled. This number is located at the intersection of the marginal frequency row and marginal frequency column. There are 620 underclassmen who were polled in the survey.
Calculate the approximate percentage of underclassmen interested in taking a Mandarin course next year.

Answer:
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x

Step-by-step explanation:
Find the value of x that makes m parallel n .
The required value of the x that makes the line n parallel to line m is 5.
Given that, to determine the value of x that makes the lines m and n parallel to each other.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
For the lines m and n to be parallel the alternate opposite angle must be equal. So,
3x - 15 = 180 - 150
3x - 15 = 30
3x = 30 - 15
3x = 15
x = 15 / 3
x = 5
Thus, the required value of the x makes line n parallel to line m is 5.

Answer:
40000 and 12.5% respectively
Step-by-step explanation:
soln:
given,
cost price(c.p)=320000
selling price(s.p)=280000
loss(l),loss percentage(l%)=?
we know,
l=c.p-s.p
or,l=320000-280000

now,
l%=l/c.p*100%
or,l%=40000/320000*100%

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50
Answer:
A: Negative cash flow, $50
Step-by-step explanation:
Bob makes $3000 a month.
Every month he has to pay $950:
3000 - 950 = 2050
Pay an additional $250:
2050 - 250 = 1800
And another additional $1850:
1800 - 1850 = -50
Therefore, he has a negative cash flow of $50 a month.

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?
70
85
110
143
Answer:
A
Step-by-step explanation:
Let T represent the total number of turtle nests found during the season.
The 28 turtle nests was 40% of 0.4 of the total. Therefore:
[tex]28=0.4T[/tex]
So, to find T, divide both sides by 0.4:
[tex]T=70[/tex]
So, the total number of turtle nests the group found during tthe season was 70.
Hence, our answer is A.

Jasmine bought 3 slices of cheese pizza and 2 slices of pepperoni pizza for a total cost of $11.75. Keegan bought 2 slices of cheese pizza and 1 slice of pepperoni pizza for a total cost of $7. What is the cost of one slice of CHEESE pizza?
Answer:
$2.25
Step-by-step explanation:
Let c represent the price of cheese pizza and let p represent the prize of pepperoni pizza
3c + 2p= 11.75
2c + 1p = 7
Solve using elimination method
3c + 2p= 11.75 × 2
2c + 1p = 7 × 3
6c + 4p = 23.5
-
6c + 3p = 21
p = 2.5
Substitute 2.5 for p in equation 1
3c + 2p= 11.75
3c + 2(2.5) = 11.75
3c + 5 = 11.75
3c = 11.75-5
3c = 6.75
c= 6.75/3
c= 2.25
Hence the price of one slice of cheese pizza is $2.25
Answer:
$2.25
