How would 125% be expressed as a decimal. You also need to explain what is the rule in changing Percent to decimal . Give another 3 examples . pa help po ty po in advance ❤
Answer:
[tex]\frac{45}{100}\\\\ \frac{9}{10}[/tex]
[tex]\frac{10}{100} = 10%[/tex]
Step-by-step explanation:
125 % can be expressed as decimal as
[tex]\frac{125}{100} \\\frac{25}{20} \\\frac{5}{4}[/tex]
Rule in changing Percent to decimal
a) Divide a percent by 100
b) Remove percent sign
example
30%
= 3/10
45 %
[tex]\frac{45}{100}\\\\ \frac{9}{10}[/tex]
[tex]\frac{10}{100} = 10%[/tex]

Measure of angle s:
Sum all angles of triangle is = 180 degrees
So,
31 + 58 + x = 180
x = 180 - 31 - 58
x = 91
Measure of angle s: 91 degrees

Please help!! Use the discriminate to determine the number of solutions and types of solutions for the quadratic equation.
Discriminant=__
Number of solutions for the quadratic equation=___
a^2+3a=7
Answer:
two unequal, complex roots
Step-by-step explanation:
Rewrite this quadratic as a^2 + 3a - 7 = 0. The coefficients are {1, 3, -7}. The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.
Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.

Sunrise, a bed-and-breakfast hotel, charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night. Craig wants to book a hotel for 5 nights.
Answer:
Sunrise $450 Bright Eyes $475
Step-by-step explanation:
Let x= number of days
Sunrise:
(25 + 85x)= total cost
(25+85(5))= $450
Bright Eyes:
(95x)= total cost
(95(5))= $475
The Bright eyes hotel would be more cost efficient than the Sunrise hotel.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sunrise, a bed-and-breakfast hotel, that charges a one-time deposit of $25 plus $85 per night. Another bed-and-breakfast hotel called Bright Eyes charges a flat rate of $95 per night.
The total cost for 5 nights at Sunrise hotel would be -
C(s) = 25 + 85 x 5 = $450
The total cost for 5 nights at Bright eyes hotel would be -
C(b) = 95 x 5 = $475
Therefore, the Bright eyes hotel would be more cost efficient than the Sunrise hotel.

Simplify the expression
Hi there!
So what we need to do here is this...
Multiply -3/4 with there own parentheses and multiply 2 with it’s own parentthese also.
[tex]- \frac{3}{4} x 5p = 3 \frac{3}{4} p[/tex]
[tex]-\frac{3}{4} x 12 = 9[/tex]
Then do the second parenthese...
[tex]2x8=16[/tex]
[tex]2x - \frac{1}{4} = \frac{1}{2}p[/tex]
Add them like this...
[tex]( 3 \frac{3}{4}p + 9 ) + ( 16 -\frac{1}{2}p )[/tex]
Simplflied it again.../ since 3 3/4 and 1/2 both have p, add them...
[tex]3 \frac{3}{4} + - \frac{1}{2}p=3 \frac{1}{4}p[/tex]
Add the rest:
[tex]3 \frac{1}{4}p+9+16[/tex]

solve for x. 9 4 13.5 x+4
Answer:
x = 2
Step-by-step explanation:
The parallel lines divide the transversals into proportional segments, that is
[tex]\frac{x+4}{13.5}[/tex] = [tex]\frac{4}{9}[/tex] ( cross- multiply )
9(x + 4) = 54 ( divide both sides by 9 )
x + 4 = 6 ( subtract 4 from both sides )

What is the value ofx?
Answer:
x = 39
Step-by-step explanation:
∠JKL and ∠LKM are complementary angles meaning they have a sum of 90° Knowing this, we can create an equation to solve for x.
2x - 14 + 26 = 90
2x + 12 = 90
2x = 78
x = 39

Solve the quadratic equation.
3x^2=81
Answer:
3x^2=81
x²=81/3
x=√27=3√3
Step-by-step explanation:
3x²=81
With this we have to square root both sides to find the value of x.
[tex] \sqrt{3 {x}^{2} } = \sqrt{81} [/tex]
So the x will cancel the square root sign so;
[tex]3x = \sqrt{81} [/tex]
And now we have to find the square root of 81 which is 9, because when we multiply 9 by 9 we are going to be get 81 so the square of 9 is 81 and the square root of 81 is 9
So;
[tex]3x = 9[/tex]
And then we divide both sides by 3 to find the value of x ;
[tex] \frac{3x}{3} = \frac{9}{3} [/tex]
[tex]x = \frac{9}{3} [/tex]
[tex]x = 3[/tex]
