In 1 minute, Alex can type 44 words. While working on a project, Alex types from 10:00 AM until 1 AM, He takes a break from 1 0:25 AM to 10:40 AM. At the same rate, how many words did he type?
Answer:
39600 words
Step-by-step explanation:
Given data
In 1 minute, Alex can type 44 words
from 10:00 AM until 1 AM= 15 hours
15 hours to minutes= 15*60= 900 minutes
Hence in In 1 minute, Alex can type 44 words
in 900 minutes he will type x words
cross multiply
x= 900*44
x= 39600 words
Hence he will type 39600 words

Answer:
Point A(5, -1) is mapped to A'(1, 5)
The rule is:
(x, y) → (-y, x)This is 90° anticlockwise rotation
Point B(-4, 6) will map to:
B(-4, 6) → B'(-6, -4)What is the slope of the line through the points (4, -7) and (9, 2)?
the answer
y/x so its 9/5

If 50% of a number is 6o, find 5% of that number.
Answer:
We have, 50% × x = 60
or,
50
100
× x = 60
Multiplying both sides by 100 and dividing both sides by 50,
we have x = 60 ×
100
50
x = 120
If you are using a calculator, simply enter 60×100÷50, which will give you the answer.

Suppose f(x)= 4x – 2
and g(x) = -2x + 1.
Find the value of
f(-1)/g(-3)
Step-by-step explanation:
f(-1)=4*(-1)-2=-4-2=-6
g(-3)=-2*(-3)+1=6+1=7
f/g=-6/7
The quotient of a number and 6 decreased by 10 is equal to 2.
Answer:
6
Step-by-step explanation:

Answer:
IS a parallelogram
Step-by-step explanation:
The slope formula for the slope of the line between points (x1, y1) and (x2, y2) is ...
m = (y2 -y1)/(x2 -x1)
The distance formula for the length of that same line is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, you're asked to use each of these formulas 4 times, once for each side of the quadrilateral. I find it convenient to let a calculator or spreadsheet do the repetitive calculations. The result is attached.
The attachment shows that opposites sides have the same length and slope, so are parallel. The quadrilateral is a parallelogram. (The two points used in each calculation are the ones on the result line and the line immediately below. That is why point B is copied to the end of the list.)
_____
Additional comments
There are much simpler ways to prove the figure is a parallelogram. My favorite is to add the coordinates of the end points of the diagonals:
B +D = (-2+6, -9-3) = (4, -12)
C +E = (0+4, -5-7) = (4, -12)
These values being the same demonstrates the midpoints of the diagonals are coincident. That will only be the case if the quadrilateral is a parallelogram.
__
If you must use slope and distance formulas, showing either pair of opposite sides is parallel and have the same length is sufficient to guarantee that the other two sides are also parallel and have the same length. That is, the calculations required in this problem only need to be applied to one pair of opposite sides. (Using a spreadsheet, it's not a lot of extra work to do the calculations for both pairs of opposite sides.)
will someone help with this problem?

Solve the following system of equations using the substitution method.
The problem- y= -2x+11
3x + y = 18
Answer:
x = 7
y = -3
Step-by-step explanation:
the first equation is already solved for 'y' so we can substitute '-2x+11' for 'y' in second equation
3x + (-2x + 11) = 18
x + 11 = 18
x = 7
solve for 'y'
y = -2(7) + 11
y = -14 + 11
y = -3
Enter the value of n so that the expression (5y - 2.3) + (-2y -4.3)
is equivalent to (3y-n).
Answer:
Step-by-step explanation:
(5y - 2.3) + (-2y - 4.3) = 3y - n Remove the brackets
5y - 2.3 - 2y - 4.3 = 3y - n Combine like terms
3y - 6.6 = 3y - n Subtract 3y from both sidess
- 6.6 = - n Divide by - 1
6.6 = n

Someone plz help me I will give brainliest btw it’s not “decimals”
Answer:
It will not fit.
Step-by-step explanation:
The mat is 1/2 by 2/3. So, lets add that together.
1/2 + 2/3 = 7/6
Now there are 24 sixths in a fourth.
So subtract 24 - 4 = 17
Final answer would be 17/4. Still way to big to fit in the 1/4 step.
Hope this Helps!!:)
btw. Im back home now :)
