Answer:
I assume you know Arithmetic Progression .
so, we have to find the first and last 4-digit number divisible by 5
first = 1000 , last = 9990
we have a formula, 
= a + (n-1)d
here, is the last 4-digit number divisible by 5.
n is the number of 4-digit even numbers divisible by 5
d is the common difference between the numbers, which is 10 in this case
a is the first 4-digit number divisible by 5
9990 = 1000 + (n-1)*10
899 = n-1
n = 900
Hence, there are 900 4-digit even numbers divisible by 5
Answer:
1467
Step-by-step explanation:
i know this because taking a negative number and a positive is like adding and then you subtract 144 and you get 1467
Answer:
PQRS and TUVW are similar.
Step-by-step explanation:
We are give two polygons.
Sides of first polygon are :
PQ = 8 ft
QR= 13ft
RS = 8ft
PS = 13ft.
Sides of second polygon:
TW = 2.4 ft
TU = 5.2 ft
UV = 2.4 ft
VW = 5.2 ft.
We can see that PQRS and TUVW are parallelograms.
Note: <em>If an angle of a parallelogram is equal to an angle of another parallelogram then parallelograms would be similar.</em>
We can see that <Q ≅ <T = 120°.
<h3>Therefore, PQRS and TUVW are similar.</h3>
Hi there!
I'm just gonna answer this and explain as I'm doing it.
So we have (3x10)x8= __x(10x8)
Well, first we look at what they did. They couldn't have changed the equation, but just moved things around.
Now, assuming you know your properties, I'm gonna go ahead and answer it.
(3x10)x8=3x(10x8)
^^
I used the Associative property, which basically says that when 3 or more #s are multiplied, the answer doesn't change no matter how you group the numbers. See how they just moved the numbers around, and only swapped the 3 for the 8?
Hope this helped!
Answer:
x = 9
FGH = 5x-3 = 42°
HGI = FGH = 42°
FGI = 42+42= 84°
Step-by-step explanation:
5x - 3 = 6x - 11
x = 9
