I WILL MARK BRAINLIEST! Solve for X
Answer:
Step-by-step explanation:
You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional. So set up two ratios that are = to each other
On the left
long side small triange / long side large triangle = base small triangle / base large triangle
On the right
hypotenuse/longest leg = hypotenuse / longest leg.
Problem A
Set up the similar Proportion
5/40 = x/20 Cross Multiply
40x = 20*5
40x = 100 Divide by 40
x = 100/40
x = 2.5
Problem B
Again set up the similar triangle proportion
15/10 = x/2 Multiply by 2
15*2/10 = x
3 = x

Answer:
a) -42
b) -23
c) -100
d) 45
Answer:
a) | -29 - 13 | = 42
b) | 39 - 62 | = 23
c) | -59 - 41 | = 100
d) | -26 + 71 | = 45
Remember, absolute value refers to a number's distance from zero on the number line, without taking direction into account. A number's absolute value can never be negative.

Select all ratios equivalent to 2:3.
Answer:
12:18 and 10:12 (i think)
Step-by-step explanation:
After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.
To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.
The given ratios are,
12:18,
3:21,
10:12
For the ratio 12:18,
Simplify it by finding the greatest common divisor (GCD) of 12 and 18.
The GCD of 12 and 18 is 6.
By dividing both numbers by 6, we get the smallest ratio of 2:3.
Moving to the ratio of 3:21,
Find the GCD of 3 and 21, which is 3.
Dividing both numbers by 3 results in the smallest ratio of 1:7.
Find the smallest ratio for 10:12.
The GCD of 10 and 12 is 2.
Dividing both numbers by 2 gives us the smallest ratio of 5:6.
Hence, the simplest form of ratios for the given ratios are:
12:18 = 2:3,
3:21 = 1:7,
10:12 = 5:6.
Hence,
The ratio equivalent to 2:3 is 12:18.

Which number has a 9 that is 1/10 the value of the 9 in 296?
195
409
981
1,956
Answer:
409
Step-by-step explanation:
This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.
1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)
The only number which has 9 as its final digit is 409

Circle question of the rug
That you needed answer for is ;
3/4 pi^2
Step-by-step explanation:
Proof 1/4 pi r^2
We can state the radius of small rug is 3ft
to show Area pi 3^2 = pi 9
If the large rug is 3x this size
then pi 9^2 = pi81
So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius
Ratio is 1 : 9 when 1cm or 1 : 3 radius
When 1 : 9 cm when 5cm or 1 : 3 radius
So if we are considering an expression of the larger rug
that shows 3: 1 more radius to that of the small.
1/4 pi^2 becomes 3/4 pi^2 of the smaller rug
As this is 3 x 1/4 pi^2 we show 3/4pi r^2
How can you use 5, 5, 5, 5, to make 24 using addition, multiplication, subtraction, or division, but without using other numbers.
Step-by-step explanation:
5×5×5=125
125-5=120
120÷5=24
Step-by-step explanation:
A number has many factors including 3 and 8. What other number must also be a factor of the same number?
Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."
Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).
Practice:
What is the square root of 49?
What is the square root of 100?
What is the square root of 625?
Memorize the squares of the numbers from 1 to 10, or 1 to 20 -- that will be very helpful in math classes.
