Answer:
B)642
Step-by-step explanation:
Between 1 and 9 , it will use 9 letters
Between 10 and 99, there are 90 different numbers and every number have 2 digits so it will use 180 letters
Between 100 and 250 , there are 151 different numbers and every number have 3 digits so it will use 453 letters

WILL MARK BRAINLIEST !!! HELP !!! determine the value of x and y that would make a parallelogram 3x-1
Answer:
x=4, y=3.
Step-by-step explanation:
Solving for x,
⟿ 3x-1=11
⟿ 3x=11+1
⟿ 3x=12
⟿ x=12/3
⟿ x=4.
Solving for y,
⟿ 5y=15
⟿ y=15/5

The angles of a quadrilateral are in the ratio 1:2:3:4. The smallest and the largest angle are
urgent pls answer asap
thank you
Step-by-step explanation:
Let the angles of quadrilateral be
X, 2x, 3x, 4x
Sum of all angles of quadrilateral = 360
X+2x+3x+4x = 360
10x = 360
X = 360/10 = 36
Ans: the four angles are
X = 36
2x = 2 X 36 = 72
3x = 3 X 36 = 108
4x 4 X 36 = 144
Please help: is the square root of -9 a whole number, integer, rational., or irrational?
Answer:
Step-by-step explanation:
None of the above.
It is a complex number. The sqrt(-9) is defined as 3i.
i is a definition brought into existence to represent the square root of -1. There is nothing at this level of math that you can point to and say this is the physical thing that is the square root (-1). It is just a math/physics definition.
Divide by rationalizing the denominator.
3+5i/10+3i
A. 25+47i/109
B. 60-18i/109
C. 100-30i/109
D. 45+41i/109
Answer:
D
Step-by-step explanation:
Multiply the numerator and denominator by the conjugate of the denominator.
Note that i² = - 1
The conjugate of 10 + 3i is 10 - 3i , then
[tex]\frac{(3+5i)(10-3i)}{(10+3i)(10-3i)}[/tex] ← Expand numerator/denominator using FOIL
= [tex]\frac{30-9i+50i-15i^2}{100-30i+30i-9i^2}[/tex] ← simplify
= [tex]\frac{30+41i+15}{100+9}[/tex]
= [tex]\frac{45+41i}{109}[/tex] → D

What is the constant of variation for y= 2/5x
Answer:
Step-by-step explanation:
This equation is of the form y = kx, where k is the constant of variation. In our case, this is 2/5. One thing that separates a direct variation from simply a line (although a direct variation does in fact represent a line when graphed), is that the graph of a direct variation will ALWAYS go through the origin. That means that it will never have the "+ k" at the end of its equation and its y-intercept is always 0.

3(y - 5) + 2 = 5
answer choices:
a. 4
b. 7
c. -4
d. 6
Answer:
answer by your own
Step-by-step explanation:lol
Answer:
D.
Step-by-step explanation:
The first step is to subtract 2 on both sides, so
3(y - 5) + 2 - 2 = 5 - 2
3(y - 5) = 3
Next, multiply by or distribute the 3 on the left side.
3y - 15 = 3
Then, add 15 on both sides.
3y - 15 + 15 = 3 + 15
3y = 18
Finally, divide by 3 on both sides.
3y/3 = 18/3
y = 6

"You are growing like a weed!” D’rek's grandmother said to him when she saw him for the
first time in a year. If D’rek grew 8 inches over the last year, and an average dandelion (a
common weed) grows 0.1 inches in one day, is D’rek growing like a weed? Justify your
answer.
growth rate:
[tex]=\frac{8}{365}[/tex]Derek is not growing like a weed because the weed grows at 0.1 inch per day, while he grows at a rate of 0.022 inch per day.
The number of days in a year = 365
The question says that D'rek grew at the rate of 8 inches in the last year'
D'reks growth rate:
[tex]=\frac{8}{365}[/tex]
= 0.022 inch per day
From the calculation above, Derek is growing at the rate of 0.022 inch per day. But the question says that the weed grows at the rate of 0.1 inch per day
In conclusion, Derek is not growing like a weed, his growth rate differs from that of the weed.

Karl drove for 4 hours. For part of the trip he drove at 50 miles per hour. For the rest of the trip he drove at 100 miles per hour.
All together he drove 250 miles.
Solve this equation for h to find out how many hours he drove at 50 miles per hour.
250 = 50h + 100(4 - h)
Answer:
3 hours
Step-by-step explanation:
250 = 50h + 100(4 - h)
250 = 50h + 400 - 100h
250 = -50h + 400
-150 = -50h
h = 3
