Megan has a bowl containing $1.95 in pennies and dimes. If she has 3 times as many pennies as she has dimes, how many pennies and how many dimes does she have?
Answer: she has 15 dimes and 45 pennies.
Step-by-step explanation:
01p+1d=1.95
p=3d
01(3d)+.1d=1.95
p=3.15
03d+.1d=1.95
p=45

A researcher observes the level of aggression of six 5-year-old boys over the course of a school day. The number of incidents for the group of boys was 2, 4, 6, 12, 8, 10. What is the mean number of aggressive acts for this group of children?
a) 9
b) 5
c) 7
d) 4
Answer:
[tex]Mean = 7[/tex]
Step-by-step explanation:
Given
[tex]Data: 2, 4, 6, 12, 8, 10.[/tex]
Required
Determine the mean
The mean of a data is calculated as thus:
[tex]Mean = \frac{\sum x}{n}[/tex]
In this case:
[tex]n = 6[/tex]
So, the formula becomes:
[tex]Mean = \frac{2+4+6+12+8+10}{6}[/tex]
[tex]Mean = \frac{42}{6}[/tex]
[tex]Mean = 7[/tex]

At the movie theatre, child admission is $5.70 and adult admission is $9.80. On Wednesday, 149 tickets were sold for a total sales of $1222.40. How many child tickets were sold that day?
Answer:
I am not sure but sold of the say 2,334
Answer:
58 child tickets
Step-by-step explanation:
5.7(x)+9.8(149-x)=1222.40
5.7x+1460.2-9.8x=1222.40
1460.2-4.1x=1222.40

Simonne predicted that she would sell 99 picture frames. She actually sold 88 picture frames. What are the values of 'a' and 'b'? Round round to the nearest tenth if necessary.
Item-
Picture frames
Approximate value-
99
Exact value-
88
Error-
Blank
Absolute error-
Blank
Ratio-
a
percent error-
b
Possible answers:
1. a= 11/99; b= 11.1%
2. a= 11/88; b= 12.5%
3. a= 88/99; b= 88/99%
4. a= 11/11; b= 100%
Step-by-step explanation:
Ratio
= Difference between Prediction and Actual / Prediction
= (99 - 88)/99 = 11/99.
Percentage Error
= Difference between Prediction and Actual * 100%
= (99 - 88) * 100% = 11.1%. (1)
The ratio (a) & percent error (b) will be option A which is a=11/99 and b= 11.11% respectively
Ratio and Percent errorRatio can be defined as difference between approximate value and exact value divided by approximate value.Percent error is ratio multiplied by 100How to solve this problem?Given
Approximate value = 99 frames
Exact value = 88 frames
Ratio (a) = (Approximate value - Exact value) / Approximate value∴ Ratio (a) = (99-88)/99
∴ a = 11/99
Ratio (a) x 100∴ Percent error (b) = (11/99) x 100
∴ b = 11.11%
So, the answer of ratio (a) & percent error (b) will be 11/99 and 11.11% respectively

Which statement is true about this equation?
-9(x + 3) + 12 = -3(2x + 5) - 3x
OA
The equation has one solution, x= 1.
OB. The equation has one solution, x = 0.
OC. The equation has no solution.
OD
The equation has infinitely many solutions.
Reset
Next
Answer: D. The equation has infinitely many solutions.
Step-by-step explanation:
Given equation: [tex]-9(x + 3) + 12 = -3(2x + 5) - 3x[/tex]
[tex]\Rightarrow -9(x)+(-9)(3)+12=(-3)(2x)+(-3)(5)-3x\\\\\Rightarrow\ -9x-27+12=-6x-15-3x\\\\\Rightarrow\ -9x-15=-9x-15\\\\\Rightarrow\ -9x+9x=-15+15\\\\\Rightarrow\ 0=0[/tex]
which is true.
This happens when all numbers are solutions.
i.e. The equation has infinitely many solutions.
Correct option : D.

- 5x2 + 2x + 9= 0
factorize
Answer:
Please check the explanation.
Step-by-step explanation:
Given the quadratic equation
5x²−2x−9 = 0
To factor the quadratic function 5x²−2x−9, we should solve the corresponding quadratic equation 5x²−2x−9 = 0.
Indeed, if x₁ and x₂ are the roots of the quadratic equation ax²+bx+c=0, then
ax²+bx+c = a(x-x₁)(x-x₂)
Now,
solving the quadratic function 5x²−2x−9 = 0
[tex]-5x^2+2x+9=0[/tex]
subtract 9 from both sides
[tex]-5x^2+2x+9-9=0-9[/tex]
Simplify
[tex]-5x^2+2x=-9[/tex]
Divide both sides by -5
[tex]\frac{-5x^2+2x}{-5}=\frac{-9}{-5}[/tex]
[tex]x^2-\frac{2x}{5}=\frac{9}{5}[/tex]
Add (-1/5)² to both sides
[tex]x^2-\frac{2x}{5}+\left(-\frac{1}{5}\right)^2=\frac{9}{5}+\left(-\frac{1}{5}\right)^2[/tex]
[tex]x^2-\frac{2x}{5}+\left(-\frac{1}{5}\right)^2=\frac{46}{25}[/tex]
[tex]\left(x-\frac{1}{5}\right)^2=\frac{46}{25} \\[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
so solving
[tex]x-\frac{1}{5}=\sqrt{\frac{46}{25}}[/tex]
[tex]x-\frac{1}{5}=\frac{\sqrt{46}}{\sqrt{25}}[/tex]
Add 1/5 to both sides
[tex]x-\frac{1}{5}+\frac{1}{5}=\frac{\sqrt{46}}{5}+\frac{1}{5}[/tex]
[tex]x=\frac{\sqrt{46}+1}{5}[/tex]
similarly solving
[tex]x-\frac{1}{5}=-\sqrt{\frac{46}{25}}[/tex]
[tex]x-\frac{1}{5}=-\frac{\sqrt{46}}{5}[/tex]
Add 1/5 to both sides
[tex]x-\frac{1}{5}+\frac{1}{5}=-\frac{\sqrt{46}}{5}+\frac{1}{5}[/tex]
[tex]x=\frac{-\sqrt{46}+1}{5}[/tex]
Thus, the roots are:
[tex]x_{1} =\frac{\sqrt{46}+1}{5},\:x_{2}=\frac{-\sqrt{46}+1}{5}[/tex]
Conclusion:
Since the roots are irrational, we do not factor further.
Therefore, we leave 5x²−2x−9 as it is.
