What is the square root of 9000?
a:b=2:3
b:c= 5:6
Show that a:c=5:9
Answer:
see explanation
Step-by-step explanation:
Expressing ratios in fractional form, then
[tex]\frac{a}{c}[/tex] = [tex]\frac{a}{b}[/tex] × [tex]\frac{b}{c}[/tex] = [tex]\frac{2}{3}[/tex] × [tex]\frac{5}{6}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{5}{3}[/tex] = [tex]\frac{5}{9}[/tex]
That is a : c = 5 : 9

Find the measures of the indicated angles pictures included!!!
Answer:
25
Step-by-step explanation:
The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Find the least number which when divided by 28, 50 and 140 leaves a remainder 7
Answer: 21
Step-by-step explanation:
First we have to find LCM (lowest common multiple) of the given number, i.e 700.
28 = 2 × 2 × 750 = 2 × 5 × 5140 = 2 × 2 × 5 × 7LCM = 2 × 2 × 5 × 5 × 7 = 700
now, let's add 7 to 700
We get the required number as 707

Can anyone help
looks like the answer C. Thousands.
In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively.
What are digits?In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.
A digit is a part of a set that, when combined, makes up a numeration system.
For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are digits.
The place value of a general abcd digit is given by
d = ones
c = tens
b = hundreds
a = thousands
So,
In the given number 72,204
4 = ones
0 = tens
2 = hundreds
2 = thousands
7 = hundred thousand
Hence "In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively".

I’ve been stuck on the same question for days now
Answer:
7
Step-by-step explanation:
You've said that both triangle are equal.
This means, both are in proportion
Let the unknown side be x
4 : 5 : x = 36 : 45 : 63
Divide LHS by 9
4 : 5 : x = 4 : 5 : 7
Since you may see x and 7 are same. So, the missing side is 7.
Answer:
Step-by-step explanation:
[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex] #1 Find same sides
So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex] #2 fill it in.
36BC= 252 #3 Cross multiply.
[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex] #4 Divide by 36
BC= 7 #5 Here's your answer!
If you want to check, plug the sides in.
[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]
[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]
The siplified fractions should all equal the same number. If they do, the triangles are similar.

Perimeter of Triangle Please. Thank you ASAP
Step-by-step explanation:
The perimeter of a parallelogram is twice the sum of the length of a longer and a shorter side.
The length can be evaluated by the distance formula between two points (x_1,y_1), (x_2, y_2)
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For the longer side,
[tex]d=\sqrt{(7-(-4))^2+(3-2)^2}=\sqrt{122}[/tex]
or the shorter side,
[tex]d=\sqrt{(7-6)^2+(3-(-2))^2}=\sqrt{26}[/tex]
Therefore, the perimeter is given by,
[tex]2(\sqrt{122}+\sqrt{26})\approx254.2[/tex]
