In a school orchestra, the ratio of girls to boys is 3 : 2. There are 75 students in the orchestra. How many boys are in the orchestra?
There were 30 boys in Orchestra.
We have,
Total students in Orchestra= 75
Ratio of Girls to Boys = 3 :2
So, Number of Girls in Orchestra
= 3/5 x 75
= 3 x 15
= 45
and, Number of Boys in Orchestra
= 2/5 x 75
= 2 x 15
= 30
Thus, 30 Boys were in Orchestra.

At Maria's Beading Boutique, 15% of the 40 beads on clearance are plastic. How many plastic beads are there on clearance?
for brainliest u got to get it right
Answer:
The answer would be 6 because 15/100 × 40/1 is 600/100 so 600 ÷ 100 is 6
There are 6 plastic beads on the clearance.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 b= 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of beads = 40
Percentage of plastic beads = 15%
The number of plastic beads.
= 15% of 40
= 15/100 x 40
= 3 x 2
= 6
Thus,
6 beads are plastic beads.

Kim has a 15 meter head start and has a walking rate of 1.5 meters per second. Write an equation that gives the relationship between Kim's distance from the starting line d and the the time t.
Step-by-step explanation:
It is given that,
Distance, d = 15 m
Speed of Kim,v = 1.5 m/s
We need to find the equation that gives the relationship between Kim's distance from the starting line d and the time t. Speed of an object is given by :
speed = distance/time
⇒ [tex]t=\dfrac{d}{v}[/tex]
Putting all the values,
[tex]t=\dfrac{15\ m}{1.5\ m/s}\\\\t=10\ s[/tex]
Hence, this is the required solution.

What’s the distance between (-2,3) and (2,1) ;; using distance formula
Answer:4.472136
Step-by-step explanation:
The formula in finding the distance between two points is given below:
[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]Now, you know the distance formula. So, let us try solving the given problem using the distance formula.
Problem: What is the distance between (-2, 3) and (2, 1), using the distance formula?
From inspection on the given problem:
[tex]\sf (x_1, y_1) = (-2, 3)[/tex][tex]\sf (x_2, y_2) = (2, 1)[/tex]Substitute the given values into the distance formula and solve for d:
[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf d = \sqrt{[2 - (-2)]^2 + (1 - 3)^2}[/tex][tex]\sf d = \sqrt{(4)^2 + (-2)^2}[/tex][tex]\sf d = \sqrt{16 + 4}[/tex][tex]\bold{d = \sqrt{20} \approx 4.47 \: units}[/tex]Therefore, the distance between two points is 4.47 units.

What is equivalent to the product (x-4) (x+9)
Answer:
x^2+5x-36
Step-by-step explanation:
x^2+9x-4x-36
Answer:
x²+ 5x - 36
Step-by-step explanation:
Given
(x - 4)(x + 9)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 9) - 4(x + 9) ← distribute both parenthesis
= x² + 9x - 4x - 36 ← collect like terms
= x² + 5x - 36
Write a rational inequality with the solution: (-2,-1)U(1, oo)
Answer:
[tex]\displaystyle \frac{x^2+3x+2}{1-x}<0[/tex]
Step-by-step explanation:
Rational Inequality
We are given the solution of rational inequality:
(-2,-1) U (1,∞)
The first set suggests a limited zone than can be obtained by a quadratic equation of the form:
[tex](x-a)(x-b)<0[/tex]
Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:
[tex](x+2)(x+1)<0[/tex]
Operating:
[tex]x^2+3x+2<0[/tex]
The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.
Thus, one possible inequality is:
[tex]\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}<0}[/tex]
The solution to the inequality (-2,-1)U(1, ∞) is (-2, ∞)
Inequality
An inequality is an expression used to show the relationship between two or more numbers and variables.
A rational inequality is an inequality that contains a rational expression.

What algebraic property is demonstrated in the equation below? 6 + 4(7x – 2) = 6 + 28x – 8
Answer:
Distributive property
Answer:
The distributive property
Step-by-step explanation:
In the equation, we can see that the 4 in 4(7x - 2) was distributed to the parentheses in the other side of the equation.
The 4 was multiplied to both 7x and -2, creating 28x - 8 on the other side of the equation.
So, this represents the distributive property.

Craig has $1850 dollars in a bank account that he uses to make automatic payments of $400.73 on his car loan. If Craig stops making deposits to that account, when would automatic payments make the value of the account zero?
Given:
Amount in the bank account = $1850
Monthly payment of can loan = $400.73
To find:
When would automatic payments make the value of the account zero?
Solution:
Craig stops making deposits to that account. So, amount $1850 in the bank account is used to make monthly payment of can loan.
On dividing the amount by monthly payment, we get
[tex]\dfrac{1850}{400.73}=4.61657[/tex]
It means, the amount is sufficient for 4 payment but for the 5th payment the amount is not sufficient.
Therefore, the 5th automatic payments make the value of the account zero.
