Answer:14 red marbles
Step-by-step explanation:
60% of the marbles are yellow and there is a total of 35 marbles.
60% of 35 is 21, so there are 21 yellow marbles.
35-21= 14,
leaving you with 14 red marbles.

do Parentheses first which would then be 8x-3=10x+5
then put "10x in the middle of 8x and -3
so
[tex]8x - 10x - 3 = 5[/tex]
then 8x-10x which would equal -2x
then you would be left with
[tex] - 2x = 5 + 3[/tex]
add the 5+3 ------>> -2x=8
(divide both sides)

What dose 750 divided by 30 equals what
Answer:
25
Step-by-step explanation:
30 goes into 750 25 times.
You can check your answer by multiplying 30 by 25 which equals 750. Therefore your answer is correct.
The 750 divided by 30 equals 25. This means that if we distribute 750 objects into 30 groups equally, each group would contain 25 objects.
When we divide 750 by 30, we can calculate the result as follows:
750 ÷ 30 = 25
Therefore, 750 divided by 30 equals 25. This means that if we distribute 750 objects into 30 groups equally, each group would contain 25 objects. Division is the arithmetic operation that allows us to determine how many times one number (the divisor) can be subtracted from another number (the dividend) without resulting in a negative value.
In this case, when we divide 750 by 30, we find that the quotient is 25. This represents the number of groups or units we can obtain when dividing 750 into 30 equal parts. Division is a fundamental mathematical operation used in various real-life scenarios, such as distributing resources, calculating averages, and solving ratio problems.

An elliptical culvert is 3.5 feet tall and 6 feet wide. It is filled with water to a depth of 0.95 feet. Find the width of the stream.
Answer:
[tex]W_s \approx5.3[/tex]
Step-by-step explanation:
From the question we are told that
Height [tex]H=3.5ft[/tex]
Weight [tex]W= 6ft[/tex]
Depth [tex]D=0.95ft[/tex]
Generally the equation for ellipses is given as
[tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]
Where
[tex]b=H/2\\b=3.5/2\\Therefore\\b=1.75\\a=W/2\\a=6/2\\Therefore\\a=3\\[/tex]
[tex]\frac{x^2}{3^2} +\frac{y^2}{1.75^2} =1[/tex]
Generally to find y in the equation [tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]
[tex]y=-b+d[/tex]
[tex]y=-1.75+0.95[/tex]
[tex]y=-0.8[/tex]
Therefore
[tex]\frac{x^2}{3^2} +\frac{(0.8)^2}{1.75^2} =1[/tex]
[tex]\frac{x^2}{3^2} =1-\frac{(0.8)^2}{1.75^2}[/tex]
[tex]\frac{x^2}{3^2} =1-0.2089795918[/tex]
[tex]X^2 =3^2(1-0.2089795918)[/tex]
[tex]X^2 =7.119183674[/tex]
[tex]X =\sqrt{7.119183674}[/tex]
[tex]X =2.66817984[/tex]
Therefore the width of the given stream is
[tex]W_s=2.66817984*2[/tex]
[tex]W_s=5.33635968[/tex]
[tex]W_s \approx5.3[/tex]

Which of the following is equivalent to sin(30°)?
Question 2 options:
A) cos(60°)
B) cos(90°)
C) sin(60°)
D) cos(30°)
Answer:
A. cos(60°)
Step-by-step explanation:
sin(30 degrees) = 0.5
cos(60°) = 0.5
cos(90°) = 0
sin(60°) = √[tex]\frac{3}{2}[/tex]
cos(30°) = √[tex]\frac{3}{2}[/tex]
so it's A.
Ace
The sin 30° is equivalent to the expression cos 60°. Then the correct option is A.
What is trigonometry?Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The equivalent is the expression that is in different forms but is equal to the same value.
The expression is given below.
⇒ sin(30°)
We know that the formula which is written as,
sin (90° - x) = cos x
Then by the above property, the expression is written as,
sin 30° = sin (90° - 30°) = cos x
sin 30° = cos 60°
The sin 30° is equivalent to the expression cos 60°. Then the correct option is A.

3 is what percent of 75?
Answer:
4%
Step-by-step explanation:
First, we turn this into a fraction:
3/75 = 1/25 = 4%
So 3 is 4% of 75
Using the percentage expression 4 percent of the number 75 is 3.
We have,
Given percentage = M
Under the condition, an expression can be written as,
M% of 75 = 3
Solve for M.
M/100 x 75 = 3
Multiply 100 on both sides.
75M = 3 x 100
75M = 300
Divide 75 on both sides.
M = 300/75
M = 4
Cross checked.
4% of 755

Which expression is equivalent to 15c+20?
Answer:
5 (3 c + 4)
Step-by-step explanation:
We factor out the 5, to get 5(3c+4)
We check by distributing the 5, and we get 15c+20 which is correct!
Hope this helps
The expression equivalent to 15c + 20 is 5(3c + 4).
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 15c + 20.
We have to find an equivalent expression of this using the distributive property.
For three numbers or expressions a, b and c, Distributive property states that,
a (b + c) = ab + ac
In the expression of 15c + 20, write each terms as a multiple of a common factor.
15c = 5 × 3c
20 = 5 × 4
15c + 20 = (5 × 3c) + (5 × 4)
= 5 (3c + 4)
Hence the correct expression which is equivalent to the given expression is 5 (3c + 4).
