Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.

The ratio of perimeters is the ratio of corresponding sides.
first : second = 8 : 6 = 4 : 3 . . . ratio of perimeters
The ratio of areas is the square of the ratio of linear dimensions.
first : second = 4² : 3² = 16 : 9 . . . ratio of areas

In triangle XYZ right angled at Y. Find the length of the hypotenuse if the length of the other two sides is 1.6 cm and 6.3 cm.
Answers
Answer:
6.5 cm
Step-by-step explanation:
From Pythagoras theorem
C^2= a^2 + b^2
Where a, b are the sides of the triangle
C= hypotenus sides of the triangle
two sides are given as 1.6 cm and 6.3cm respectively.
C^2= 1.6^2 + 6.3^2
C^2= 2.56 + 39.69
C^2 = 42.25
C= √42.25
C=6.5 cm
Hence, the length of the hypotenuse is 6.5 cm

The equation for the line of best fit shows the relationship between the number of students enrolled
The equation for the line of best fit, then predict the number of students enrolled in 2011 is [tex]y = 90.2x - 177670.2[/tex]
How to determine the equation of the line of best fitTo do this, we make use of a graphing calculator that has the following calculation summary
Sum of X = 10020Sum of Y = 15453Mean X = 2004Mean Y = 3090.6Sum of squares (SSX) = 10Sum of products (SP) = 902b = 90.2a = -177670.2A regression equation is represented as:
[tex]y = bx + a[/tex]
So, we have:
[tex]y = 90.2x - 177670.2[/tex]
Hence, the regression equation is [tex]y = 90.2x - 177670.2[/tex]

If one tenement on the Lower East Side of New York had 101 adults and 91 children, and there was an average of 8 persons in a tenement apartment, how many apartments did this tenement have?
Answers
Answer:
24 Apartments
Step-by-step explanation:
To get the total amount of people living in the apartment building, you add 101 and 92.
101+91=192 total people
You then divide this total by the amount of people staying in each apartment, which is 8.
192/8=24 apartments
This leaves you with 24 apartments, with 8 people living in each one.

If your driving 60miles an hour and you drive for 1hour how far do you travel?
Answers
Answer:
60 miles
Step-by-step explanation:
1 hour=60 miles
1 hour=60 miles
The given information in this problem gives us: the speed of r = 60 mi/hr traveled over a distance of 1 mile. We need to find how much time, t, it took to travel a distance d of 1 mile at a speed r = 60 mi/hr, that is:
d/r = t or
t = d/r
Substituting the known values for d and r into the above equation, we have:
t = 1 mi./(60 mi/hr)
t = (1/60) hr.
t = (1/60) hr. (1)
t = (1/60) hr. (60 min./1 hr.)
t = (1/60)(60/1) min.
t = 1 minute ( or 60 seconds) to travel 1 mile at a speed of 60 miles per hour.

A bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavored. How many of the cupcakes sold that day were mocha flavored?
Answers
Answer:
172
Step-by-step explanation:
200 x 0.86 = 172
172 cupcakes sold were of mocha flavoured.
What is Percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavoured.
Let the number of mocha cupcakes sold are x,
Therefore, 86% of 200 = x
x = 200*86/100
x = 2*86
x = 172
Hence, the number of mocha cupcakes sold were 172.
