Answer:
Dina took 12/8 = 3/2 hrs
So, if Masha's speed was x
3/2 x = 12-3
x = 6 mi/hr
Answer:

Find the sum of the next two numbers in the series below
20,24,33,49,_,_
A.74. B.36
C.184. D.110
Answer:
74 and 110
Step-by-step explanation:
lay out the numbers and the difference between the numbers:
20,24,33,49
+4 +9 +16
and notice the different between the amount added between the numbers
4,9,16
+5 +7
It seems the amount added to the amount added increases by 2 each time
the next two numbers in the sequence above is 9 and 11.
From that we can try to figure out what will be added to the original number by adding 9 and 11 to the difference list.
4, 9, 16, 25(added 9), 36(added 11)
and we can test those values
20,24,33,49,74(added 25),110(added 36)

The given fraction [tex](\frac{1}{16} )[/tex] can correctly be read as one divided by sixteen.
A fraction can be defined as a numerical quantity that isn't a whole number and as such has two (2) parts.
Hence, a fraction is simply a part of a whole number.
Generally, a fraction comprises two (2) main parts and these include:
Denominator: this refers to the lower part of a fraction.Numerator: this is the upper part of a fraction.Mathematically, a fraction is represented as:
[tex]Fraction \;A = \frac{1}{16}[/tex]In order to read a fraction, you will start by naming the numerator (upper part) followed by the denominator (lower part).

The table shows the mass of a substance decreasing over a period of time during a chemical experiment.
Identify a quadratic model for the mass M, given the time t. Then use the model to predict the mass at t = 11
seconds
Time (s) Mass (g)
2
94.8
5
87.9
8
81.3
B
O M(x) = -0.02x2 - 2.42x + 99.57
M(11) - 75 g
O M(x) = 0.02x2 - 2.42x + 99.57
M(11) - 1299
O M(x) = -0.02x2 - 2.42X + 99.57
M(11) = 129 g
O M(x) = 0.02x2 - 2.42x + 99.57
M(11) = 75 g
So from a table, we want to find an equation that models the mass as a function of time, we will get the equation:
M(t) = 0.02*t^2 - 2.42*t + 99.57
And with that equation, we will find that the mass after 11 seconds is 75 grams.
From the table we have the points:
(2, 94.8)
(5, 87.9)
(8, 81.3)
And we know that this follows a quadratic model, then we have:
M(t) = a*t^2 + b*t + c
Notice that from the known points, we have 3 equations:
94.8 = a*2^2 + b*2 + c
87.9 = a*5^2 + b*5 + c
81.3 = a*8^2 + b*8 + c
So we have a system of equations, we can simplify the equations to get:
94.8 = a*4 + b*2 + c
87.9 = a*25 + b*5 + c
81.3 = a*64 + b*8 + c
To solve this, we start by isolating one of the variables in one of the equations, let's isolate c in the first one.
c = 94.8 - a*4 - b*2
now we replace this in the other two equations to get:
87.9 = a*25 + b*5 + (94.8 - a*4 - b*2)
81.3 = a*64 + b*8 + ( 94.8 - a*4 - b*2)
Now we simplify these two equations to get:
-6.9 = a*21 + b*3
-13.5 = a*60 + b*6
Now we do the same thing, I will isolate b in the first equation:
b = (-6.9 - a*21)/3 = -2.3 - a*7
Now we replace this in the other equation:
-13.5 = a*60 + (-2.3 - a*7)*6
Now we can just solve this for a:
-13.5 = a*(60 - 7*6) - 2.3*6
0.3 = a*18
0.3/18 = a = 0.016
Wich can be rounded to:
a = 0.02
Then the value of b is:
b = -2.3 - a*7 = -2.3 - 0.016*7 = -2.42
And the value of c is:
c = 94.8 - a*4 - b*2 = 94.8 - 0.016*4 - (-2.42)*2 = 99.57
So the equation is:
M(t) = 0.02*t^2 - 2.42*t + 99.57
Now we can evaluate this in t = 11s to get:
M(11) = 0.02*11^2 - 2.42*11 + 99.57 = 75.37
Wich can be rounded to 75 grams.

What are the slope and y-intercept of the line?
slope = -170. y-intercept = 1020
Step-by-step explanation:
Let [tex]P_1(0, 1020)[/tex] and [tex]P_2(6, 0).[/tex] The slope can be calculated as
[tex]m = \dfrac{0 - 1020}{6 - 0} = -170\:\text{m/hr}[/tex]
So the equation can be written as
[tex]y = -170x + b[/tex]
To solve for b, let's use the values for P2:
[tex]0 = -170(6) + b \Rightarrow b = 1020[/tex]
Therefore,
[tex]y = -170x + 1020[/tex]
To find the y-intercept, let x = 0. then the y-intercept is
[tex]y = -170(0) + 1020[/tex]
or
[tex](0, 1020).[/tex]

Answer: See the drawing below
Explanation:
The region to the left of x = -3 has f(x) > 0, aka f(x) is positive. This is due to the sign chart indicating this with a + sign. The same applies from the region between x = -3 and x = -2. The graph will show f(x) above the x axis for these two regions.
When -2 < x < 0, f(x) is now negative and below the x axis. It goes above the x axis for the interval 0 < x < 2. Then it dips back down below the x axis again once it passes x = 2.
The graph below visually summarizes everything talked about. Keep in mind that there are infinitely many ways to draw a graph like this. There's not enough info to pin down one exact answer.

Angle AEB and Angle DEC are opposite angles which means they are equal in measure. Hence,
⇛ Angle AEB = Angle DEC

⇛ 9x - 3x = 42° - 8°
⇛ 6x = 34°
⇛ x = (34/6)°
To find: Angle DEC = 3(
