Polly surveyed 850 teenagers to find out their favorite type of music. She found that 32% of the teenagers surveyed like hard rock.
Part A: How many teenagers surveyed like hard rock? Show your work. (4 points)
Part B: In another survey, Damian found that 75% of the total number of teenagers surveyed like pop music. If 150 teenagers like pop music, what is the total number of teenagers that Damian surveyed? Show your work. (4 points)
Part C: Give an example of a situation in which a percentage is greater than 100%. (2 points)
Answer:
Step-by-step explanation:
A) There are 850 total teens and 32% like rock.
32% of 850 = 0.32*850 = 272 teens like rock
B) 75% of teens = 150 teens. Make total teens = x. 75%x = 150
0.75x = 150
x = 200 teens like pop
C) well...

maggie is baking 8 dozen cookies. the recipe she is using makes 24 cookies. she needs 2/3 cup of flour for one recipe. how much flour will she need?
Answer: 2 2/3 cups of flour
Step-by-step explanation:
Maggie is baking 8 dozen cookies.
8 dozen is equal to 96 cookies as 8×12=96
One recipe is equal to 24 cookies and for each recipe she'll need 2/3 cup of flour.
So you divide 96 by 24 which is equal to 4.
Therefore, you will need 4 recipes worth of flour.
4×2/3=2 2/3
So Maggie would need 2 2/3 cups of flour

Answer:
y = 0.1x - 4
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-3, 7)
Points on the y-axis (y1, y2) = (-7, -6)
First of all, we would find the slope;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
Slope = (-6 - (-7))/(7 - (-3))
Slope = (-6 + 7)/(7 + 3)
Slope = 1/10
Slope = 0.1
Next, we would write the equation using the formula;
y - y1 = m(x - x1)
y - (-7) = 0.1(x - (-3))
y + 7 = 0.1(x + 3)
y + 7 = 0.1x + 3
y = 0.1x + 3 - 7
y = 0.1x - 4
Compute and simplify the following: (a+b+c)^3
Answer:

age 16 and over: £32.70
under 16: £17.90
143 people pay and 38 of these people are under 16.
How much ticket money is collected?
Answer:
£4113.70
Step-by-step explanation:
Given that:
143 people pay ; out of which 38 are under 16 ;
Hence ; 143 - 38 = 105 are over 16
Under 16 = £17.90
£17.90 * 38 = £680.20
16 and Over : = £32.70
£32.70 * 105 = £3433.50
£(680.20 + 3433.50) = £4113.70

STD 10
Answer:
c
Step-by-step explanation:
since all the tangent(tan) angles are multiplying,
you factor tan out and multiply the numbers. that's : tan( 23+35+60+67+55)
tan(240)
tan(240) =√3

which functions have a range of
Answer:
Option (4) and (5)
Step-by-step explanation:
Option (1)
f(x) = -(x + 1)² - 4
Since, given function has the vertex = (-1, -4) and the parabola is the opening downwards,
Range of the function → (-∞, -4]
Option (2)
f(x) = [tex]2^{x+3}[/tex]
Horizontal asymptote of the function is,
y = 0
Therefore, range of the given function → (0, ∞)
Option (3)
f(x) = x² + 7x - 9
= x² + 2(3.5)x + (3.5)² - (3.5)² - 9
= (x + 3.5)²- 12.25 - 9
= (x + 3.5)²- 21.25
Vertex of the parabola is (-3.5, -21.25) and parabola is opening upwards.
Therefore, range of the function → [-21.25, ∞)
Option (4)
f(x) = -4x + 11
Range of this function is (-∞, ∞).
Option (5)
f(x) = [tex]\frac{2}{3}x-8[/tex]
Range of the function is (-∞, ∞).
Options (4) and (5) are the correct options.

Step-by-step explanation:
Answer:
[tex]\sqrt{85}[/tex]
Step-by-step explanation:
Distance formula.
(-7, -2) (2, -4)
-7 minus 2, you get -9. Squared is 81.
-2 minus -4 gets you 2. Squared is 4.
Add 81 & 4. You get 85.
Square root 85, there's your answer.

Step-by-step explanation:
The number of defective laptops = 6/145 * 100 as a percent.
The number of defective laptops = 4.13% in a sample of 145
A: False. The percentage should be the same for 290 laptops. The % does not change. The number of defective laptops will change (12)
B: True. It is a reason assertion that about 4% of all laptops will be defective.
C: True. It is not reasonable to assume that only 0.5 laptops will be defective. .5% is too small.
D: True. 10% is too high.
E: False. The variation should not be much.

Answer:
3 7/16
Step-by-step explanation:
Answer:
Step-by-step explanation:
improper fraction you take the whole number, multiply it by the denominator and add the numerator. That number goes on top and you keep the denominator the sam.
2 1/2 in an improper fraction is 5/2
1 3/8 in an improper fraction is 11/8
keep change flip
keep the first fraction
change multiplication to division and flip the second fraction
5/2 x 11/8
5/2 divided by 8/11
answer is 3 7/16
what expression is equivalent to 1/3(9x+12)+ 4x+6
Multiply 1/3 and 9, and 1/3 and 12 first. Or divide 9 and 12 by 3, that also works.
3x+4+4x+6
Now combine like terms.
3x+4x=7x
4+6=10
The final expression is 7x+10

Option 2
Step-by-step explanation:
it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16
Answer:
2 15/16
Step-by-step explanation:
We need to make sure all fractions have the same denominator.
The LCM (least common denominator) is 16.
Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.
1/2: 1x8= 8, 2x8= 16→ 8/16
3/8: 3x2= 6, 8x2= 16→ 6/16
Now every add everything all up.
8/16 + 6/16 + 2 1/16 = 2 15/16
2 15/16 is our answer.
