1. A 2.D
Step-by-step explanation:
G is the number of girls who attended so that will be our product.
Since 75% of the girls attended the dinner and there are 12 girls on the team we are trying to find a part of the team that attended the dinner so
we would multiply a decimal times the whole.
Convert 75% into a decimal
[tex] \frac{75}{100} = 0.75[/tex]
Multiply that by 12 to equal G
[tex]0.75(12) = g[/tex]
So the answer is A
Kim pick 2 1/3 lbs every 1/4 hour. We are asked how many she pick every hour.
Let set up a fraction to make the equation equivalent
[tex] \frac{2 \frac{1}{3} }{ \frac{1}{4} } = \frac{x}{1} [/tex]
1/4 goes into 1 4 times. so we would multiply 4 by 2 1/3 to find the x value.
[tex] 2\frac{1}{3} \times 4[/tex]
[tex]2 \frac{1}{3} \times \frac{12}{3} [/tex]
[tex] \frac{7}{3} \times \frac{12}{3} [/tex]
[tex] \frac{84}{9} [/tex]
[tex]9 \frac{3}{9} [/tex]
[tex] 9\frac{1}{3} [/tex]
so the answer is D

Find the measures of all angles and sides help
Answers
Answer:
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees. Both angles are 36 degrees so that's 72 degrees.
Angle L = Angle J (Opposite angles are equal)
Angle L = 98
Angle K + Angle L = 180 (Adjacent angles are supplementary)
Angle K + 98 = 180
Angle K = 180 - 98
Angle K = 82
Angle M = Angle K (Opposite angles are equal)
Angle M = 82
The Washington Monument in Washington, D.C. is surrounded by a circle of 50 American flags that are each 100 feet from the base of the monument. The distance from the base of a flag pole to the top of the monument is 564 feet. What is the angle of elevation from the base of a flag pole to the top of the monument?
Answers
Answer:
Step-by-step explanation:
cosx=100/564
x=arccos(100/564)
x=79.79 degrees (to the nearest hundredth of a degree)
The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.
Calculation of the angle of elevation;Since there is 100 feet from the base of the monument.
And, The distance from the base of a flag pole to the top of the monument is 564 feet
Now the angle should be like
cosx = 100/564
x = arc cos(100/564)
x=79.79 degrees
hence, The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.

---the system of simoultanious equation
X+2y+z=6
2x+y+2z=6

Answers
Answer:
The system of equations has no solution.
Step-by-step explanation:
Let the following system of linear equations:
[tex]x +2\cdot y + z = 6[/tex] (1)
[tex]2\cdot x + y + 2\cdot z = 6[/tex] (2)
[tex]x + y + z = 5[/tex] (3)
Since the quantity of equations and variables are the same, there is only one solution to this system. First, we clear [tex]x[/tex] in (3):
[tex]x = 5 - y - z[/tex]
And make substitution both in (1) and (2):
[tex](5-y-z) +2\cdot y + z = 6[/tex]
[tex]2\cdot (5-y-z)+y+2\cdot z = 6[/tex]
[tex]y = 1[/tex] (4)
[tex]y = 4[/tex] (5)
Which lead to a contradiction, since [tex]4\ne 5[/tex]. Therefore, the system of linear equations has no solution.

In the year 2005, a person bought a new car for $24500. For each consecutive year
after that, the value of the car depreciated by 9%. How much would the car be worth
in the year 2008, to the nearest hundred dollars?
Answers
because, in three years it would have depreciated by 18% (9%*3=18) so you would subtract 18% off of $24500
Answer:
18500
Step-by-step explanation:
Percent decrease:
\text{Multiply by }(1-r)=(1-0.09)=(0.91)
Multiply by (1−r)=(1−0.09)=(0.91)
2005: \color{green}{24500}
2005:24500
2006: \color{green}{24500} (0.91) = \color{blue}{22295}
2006:24500(0.91)=22295
2007: \color{blue}{22295} (0.91) = \color{red}{20288.45}
2007:22295(0.91)=20288.45
2008: \color{red}{20288.45} (0.91) = \color{orange}{18462.49}
2008:20288.45(0.91)=18462.49

Answers
Answer: 1000 HK dollars has the same value as 188.15 NZ dollars.
Step-by-step explanation:
We know that:
1 US dollar = 7.76 HK dollars
1 US dollar = 1.46 NZ dollars.
We have 1000 HK dollars, and we want to know the value in NZ dollars.
First, let's rewrite the 1000 HK dollars in US dollars.
Here we use the relation:
1 US dollar = 7.76 HK dollars
Then:
1 = (1 US dollar/7.76 HK dollars)
Then we can write:
1000 HK = (1000 HK)*1 = (1000 HK)*( (1 US /7.76 HK ))
1000 HK = (1000 HK/7.76 HK)* 1 US = 128.87 US
1000 HK = 128.87 US
Now we can use the relationship:
1 US = 1.46 NZ
Then:
1 = (1.46 NZ)/(1 US)
So we can rewrite:
128.87 US = (128.87 US)*1 = (128.87 US)*( (1.46 NZ)/(1 US))
128.87 US = (128.87 US/1 US)*1.46 NZ = 188.15 NZ
Then:
1000 HK = 128.87 US = 188.15 NZ
So we can conclude that 1000 HK dollars has the same value as 188.15 NZ dollars.
For f (x) = 2x+1 and g(x) = x2 - 7, find (fºg)(2).
Answers
Answer:
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
