There are 272 people in an audience. The ratio of adults to children is 5 : 3. How many are children? (please answer)
Answer:
There are 102 children
Step-by-step explanation:
Let us solve the question
∵ There are 272 people in an audience
∴ The total number of people = 272
∵ The ratio of adults to children is 5: 3
→ Find the sum of the two parts of the ratio
∴ The sum of the parts of the ratio = 5 + 3 = 8
→ By using the ratio method
→ Adults: Children: People
→ 5 : 3 : 8
→ A : C : 272
→ By using the cross multiplication
∵ C × 8 = 3 × 272
∴ 8C = 816
→ Divide both sides by 8
∴ C = 102
∵ C represents the number of children
∴ There are 102 children

If x – 9 is a factor of x2 – 5x – 36, what is the other factor?
Answer: (x+4)(x−9)
Step-by-step explanation:
Answer:
(X - 9) is one factor
(X + 4) is the other factor
Step-by-step explanation:
You can factor polynomials with guess work or with polynomial division
To factor using guess work search for a number that will multiply with -9 to equal -36 and add with -9 to equal -5.
In order for -9 to add with another number and equal -5 you need to add 4 to it. And because -9 will multiply with 4 to equal -36 as well, 4 is confirmed to be the other factor. You can write out the factor as (x + 4)

1. Given a right triangle ABC, find the following trigonometric ratios with sides AB = 6, BC = 8 and AC = 10 units. Hint: draw and label your triangle.
a) sin A = 0.13
b) cos A = 0.99
c) tan A = 0.02
d) sin C = 0.01
e) cos C = 0.99
2. Looking back at question 1,
a) which vertex has the right angle? How do you know? B has a vertex. I know this because angle A and and C connect to angle B, and angle B it the corner of a right angle.
b) what do you notice about sine and cosine of complementary angles? The sine of A is different from the sine of C, and the Cosine of A is the same as the cosine of C
Answer:
Q1.
AC is the greatest side, therefore is hypotenuse. AB and BC are legs.
B is 90 deg as the two legs cross at this point.
Ratios:
sin = opposite / hypotenusecos = adjacent / hypotenusetan = opposite / adjacentBC is opposite to A and adjacent to C
AB is adjacent to A and opposite to C
sin A = cos C = 8/10 = 4/5cos A = sin C = 6/10 = 3/5tan A = cot C = 8/6 = 4/3tan C = cot A = 6/8 = 3/4Q2.

Is (2, 10) a solution to this system of equations?
y = 4x + 2
y = x + 8
Answer:
Yes, (2, 10) is a solution to this system:
y = 4x + 2
y = x + 8
Step-by-step explanation:
When graphed, the two equations cross at (2,10) making it a solution.
Answer:
Yes
Step-by-step explanation:
If y=4x+2 and y=x+8, then 4x+2=x+8
4x+2=x+8
4x=x+6
3x=6
x=2
Plugging this into the original equation "y=x+8", we obtain the result that y=10.
This means, (2, 10) is a solution to the system.

Answer:
Neither
Step-by-step explanation:
Triangles are similar if their angles are the same, and if the sides are changed by a proportional ratio. The angles for FED and ZXY are not the same. Therefore, they are not similar
Answer:
D. Neither
Step-by-step explanation:
Similar triangles are scaled versions of each other. Two triangles that are similar will have congruent angles. Hence, to find a triangle that is similarto ABC, the angles of the other triangles will be congruent to the given angles of ABC. As one can see, no other triangle has congruent angles to ABC, and hence the answer is D, neither of the two triangles are similar to ABC.

Circle A has center of (6, 7) and a radius of 4, and circle B has a center of (2, 4) and a radius of 16. What steps will help show that circle A is similar to circle B?
Translate circle A using the rule (x + 4, y + 3).
Rotate circle A 45° about the center.
Dilate circle A by a scale factor of 4.
Reflect circle A about the origin.
Answer:
c took quiz
Step-by-step explanation:
Circle A can be made similar to circle B by dilating circle A by scale factor 4.
Circles can be made similar by performing transformations such as dilations, translation, etc.
The given parameters are:
Circle A
[tex](x,y) = (6,7)[/tex] --- center
[tex]r=4[/tex] --- radius
Circle B
[tex](x,y) = (2,4)[/tex] --- center
[tex]r = 16[/tex] --- radius
To do this, we simply make both circles have the same radius.
Given that:
[tex]r_A=4[/tex] --- radius of A
[tex]r_B = 16[/tex] --- radius of B
Dilating the radius of A by 4 will make both circles have the same radius.
i.e.
[tex]R = r_A * 4[/tex]
[tex]R = 4 * 4[/tex]
[tex]R = 16[/tex]
Now, the new radius of A is 16; same as B
Both circles now have the same radius, means that the circles are similar.

Answer: 15.199
Step-by-step explanation:
Using the Pythagorean theorem, we know that a²+b²=c²
In this case, we know that c is 16, and that b is 5.
We can rearrange the equation so that it becomes a²=c²-b²
a²=16²-5²
a²=256-25
a²=231
√a²=√231
a=15.199
The product of 5 and x is at least 25
Answer: 5n≥25 and if you divide 5 on both sides, n≥5 (I don't know if you are supposed to solve or simply put it in the equation form).
Step-by-step explanation:
Molly's hair was 20 inches long. Three years later it was 53 inches long. What was the percent increase, to the nearest hundredth, of Molly's hair length.
Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%
Which ordered pair is a solution to the equation y = -6x?
(12, -2)
(3,-9)
-10.60)
(18, -3)
Answer:
(-10; 60)
Step-by-step explanation:
y = -6x
(12; -2)
-2 = -6 · 12
-2 = -72 - no
(3; -9)
-9 = -6 · 3
-9 = -18 - no
(-10; 60)
60 = -6 · (-10)
60 = 60 - yes
(18; -3)
-3 = -6 · 18
-3 = -78 - no
Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some Sour Straws for $1.50 each. How many Sour Straws can Jamal purchase with the money that he has? Variable: ______________________________ Inequality: ______________________________ Solution: ______________________________
Answer: Variable: y= Number of sour straws.
Inequality: 7.50+1.50y ≤ 15
Solution: y ≤ 5
Step-by-step explanation:
Let y= Number of sour straws.
Cost for nachos = $7.50
Cost per sour straw = $1.50
Total cost = 7.50+1.50y
Money he has $15
Total cost must be less than orequal to the money he has.
So required inequality: 7.50+1.50y ≤ 15
Subtract 7.50 from both sides
[tex]1.5y\leq 7.5\\\\\Rightarrow\ y\leq\dfrac{7.5}{1.5}\\\\\Rightarrow\ y\leq 5[/tex]
He can buy at most 5 sour straws.
2x^4=9x^2 solve by factoring
Step-by-step explanation:
2x⁴ = 9x²
2x⁴ - 9x² = 0
x²(2x² - 9) = 0
Either x² = 0 or 2x² - 9 = 0.
When x² = 0, x = 0.
When 2x² - 9 = 0, x² = 9/2, x = ± 3/√2.
Hence the solutions are
x = 0, x = 3/√2 and x = -3/√2.

write the linear equation in slope intercept form.
4x+y=1
Answer: y=-4x+1
Step-by-step explanation:
The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:
4x+y=1
(4x+y)-4x=1-4x
y=1-4x
y=-4x+1
