a) 3.2 ÷ 0.8 = ? please explain how you got it and b) 7.5 ÷ 0.5 also please explain how you got it i'll give the brain thing
Answer: To solve a division problem of the form a ÷ b = c, you need to find the value of c that makes the equation true. This means that if you multiply b by c, the result should be equal to a.
a) In the problem 3.2 ÷ 0.8 = ?, we are looking for the value of c that makes the equation true.
To solve this problem, we can multiply 0.8 by c to find the value of c that makes the equation true:
0.8 * c = 3.2
Dividing both sides of the equation by 0.8, we get:
c = 4
Therefore, the value of c that makes the equation 3.2 ÷ 0.8 = ? true is 4.
b) In the problem 7.5 ÷ 0.5 = ?, we are looking for the value of c that makes the equation true.
To solve this problem, we can multiply 0.5 by c to find the value of c that makes the equation true:
0.5 * c = 7.5
Dividing both sides of the equation by 0.5, we get:
c = 15
Therefore, the value of c that makes the equation 7.5 ÷ 0.5 = ? true is 15.

Step-by-step explanation:
a. we konw triangle have 180°
b. A straight line have 180°, so
∠abc=180-5x-12=168-5x,
∠bca=180-10x+37=217-10x
∠cab=180-9x-1=179-9x
then add them all 564 - 24x = 180
c.384=24x, x=16
d.so ∠bca=217-10·16=57.
Answer:
m∠BCA = 57°-------------------------------------------
Sum of exterior angles is 360°:
9x + 1 + 5x + 12 + 10x - 37 = 36024x - 24 = 36024x = 384x = 384/24x = 16The exterior angle at vertex C is:
10x - 37 = 10*16 - 37 = 160 - 37 = 123The ∠BCA is the linear pair with 123°:

Which expression is not equivalent to logp 36? 1. 6 log 2 2. log 9+ Iog, 4 O 3 2 logb 6 4. log 72 logp 2
log 30+ log 6 is not equivalent to log 36
What is equivalent expressions?Equivalent expressions are expressions that perform the same function not with standing their appearance. If two algebraic expressions are equivalent, they have the same value when the same value(s) for the variable are used (s).
The original phrase is as follows
Log 36
Following that, we write the alternatives (a) log 2+ log 18
Apply the logarithmic rule log 2+ log 18 log (218)
Log 2 plus log 18 log (36)
Remove the bracket
Log 2 plus log 18 log36
(a) Log 2+ Log 18 is the same as log 36.
(b) Log 30 plus log 6
Use the logarithms’ law. 30 logs or more 6 logs (30 x 6)
Log 30 plus log 6 Equals log (180)
Remove the bracket
Log 30-plus log 6-log180
Hence,
(c) Log 30+log 6 does not equal log 36.

Seacausus stadium has a seating capacity for 25,000 spectators. The stadium has 25 exits and can be vacated in 20 minutes. The time taken to exit the stadium varies directly with the number of spectators and inversely with the number of exits. Determine the time taken for 21,000 spectators to vacate the stadium, if only 15 exits are functional.
The time taken for 21,000 spectators to vacate the stadium, if only 15 exits are functional is 28 minutes
How to determine the time taken for 21,000 spectators to vacate the stadium?
A variation is a relation between a set of values of one variable and a set of values of other variables
Let E, N and T represent the number of exits, the number of spectators and the time taken to exit the stadium respectively
We can write the variation as:
T α N/E
T = kN/E (where k is constant of proportionality)
when N = 25,000, E = 25, T = 20:
T = kN/E
k = TE/N
k = (20×25)/25000 = 0.02
when N = 21,000 and E = 15:
T = kN/E
T = (0.02×21,000)/15 = 28 minutes

Suppose m = 2 + 6i, and║m + n║ = 3√10, where n is a complex number.
a. What is the minimum value of the modulus of n?
b. Provide one example of the complex number, n.
Answer:
the modulus of a complex number z = a + bi is:
Izl= √(a²+b²)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nl = 3√10
√(a² + b²+ 2²+ 6²)= 3√10
√(a^2 + b^2 + 40) = 3√10
squaring both side
a²+b²+40 = 3^2*10 = 9*10 =90
a²+b²= 90 - 40
a²+b²=50
So,
|n|=√(a^2 + b^2) = √50
The modulus of n must be equal to the square root of 50.
now
values a and b such
a^2 + b^2 = 50.
for example, a = 5 and b = 5
5²+5²=25+25= 50
Then a possible value for n is:
n = 5+5i
Factor by gcf 5x + 20 please someone

How do you find the missing side of a right triangle without a calculator?
The missing side of a right triangle without using a calculator can be found by using the Pythagoras theorem .
What is Pythagoras Theorem ?
The Pythagoras Theorem states that the square of the hypotnuse (longest side) is equal to the sum of the square of the perpendicular and base .
that means : [tex]Hypotnuse^{2} = Perpendicular^{2} + Base^{2}[/tex] ;
let the missing side of the right triangle be the hypotnuse ;
So , missing side can written as : [tex]Hypotnuse = \sqrt{Perpendicular^{2} + Base^{2}}[/tex] .
For Example : Let the right triangle has sides lengths as perpendicular = 6 and hypotnuse = 10
The length of side "base" is unknown.
So , to find length of side b, we put the known values into theorem:
[tex]10^{2} = 6^{2} + Base^{2}[/tex] ;
[tex]base^{2} = 100 - 36[/tex] ;
So , the missing side "base" = 8 ;
Therefore , the missing side without using calculator can be found by the Pythagoras Theorem .

A horse walks 4224 feet in 12 minutes at this rate how many yards does a horse walk in twelve minutes.
Answer:
1408 yards
Step-by-step explanation:
A horse walks 4224 feet in 12 minutes, so to find out how many yards the horse walks in twelve minutes, we need to convert 4224 feet to yards. Since there are 3 feet in a yard, we can divide 4224 by 3 to find the number of yards:
4224 feet / 3 feet/yard = 1408 yards
So a horse walks 1408 yards in 12 minutes.

2a+9b=4c
Answer:
This equation involves three variables: a, b, and c. Each variable is multiplied by a coefficient and then added together to equal a constant. To solve the equation, we must first determine what the value of the three variables are. To do this, we must use the coefficients to isolate each variable. We can start by isolating c. Divide both sides of the equation by 4 to get 2a + 9b = c. Now we can isolate b by subtracting 2a from both sides to get 9b = c - 2a. Divide both sides by 9 to get b = (c - 2a)/9. Finally, we can isolate a by subtracting 9b from both sides to get 2a = 4c - 9b. Divide both sides by 2 to get a = (4c - 9b)/2. Once we have the values of the three variables, we can substitute them into the original equation to check our work.
Step-by-step explanation:
Answer:
a=\frac{4c-9b}{2}

Solve for x. The triangles in each pair are similar.
Apply arithmetic operations on both sides of the equation to move the variable to one side and all other values to the opposite side.
How Do You Solve for x?Let's begin with a basic equation: x + 2 = 7.
How may x be obtained on its own?
x + 2 - 2 = 7 - 2 x = 5 after deducting 2 from both sides.
Put the solution, x = 5, back into the equation to confirm it. We get 5 + 2= 7.
Since LHS = RHS
In the triangle, find x.
Use triangle properties or the Pythagorean theorem to find the value of x, the unknown side or angle in a triangle.
Let's use an example to better understand how to solve for x in a triangle.
Using the Pythagorean theorem, we obtain AC2 = AB2 + BC2 where x2 = 72 + 242 x = 49 + 576 x = 625 x = 25 units.
