9 999 999 in words is read as nine million, nine hundred and ninety-nine thousand, and nine hundred and ninety-nine
By partitioning, we can write 9 999 999 as follow
9 000 000 + 900 000 + 90 000 + 9000 + 900 + 90 + 9
If we start at the first digit of '9' on the left, the next digit is ten times smaller than the previous one.
∠P=∠R, ∠Q=2∠R
the three angles make a total of 180, so
∠P+∠R+∠Q=180
∠R+∠R+2∠R=180
∠R=45
∠P=45, ∠Q=90
Answer:
$7
Step-by-step explanation:
a) First let's organize the information:
The cage cost $40
two bowls cost the same
the total was $54
b) Put it as an equation
40+x+x= 54
c) we will subtract 54-40 and get 14
d) divide 14 by 2 and get 7 for the cost of each bowl.
Hope you understand it ;)
Divide 3 1/2 by 7= 1/2 a cup per person
A line is perpendiculat to another which has a slope of m if the perpendicular line has a slope of -1/m.
That means that if the product of slopes of two lines is -1, the two lines are perpendicular.
Here, y1=-7/4x, or m=-7/4
The perpendicular should have a slope of -1/m=-1/(-7/4)=4/7
