Answer:
324 degrees
Step-by-step explanation: A circle has 360 degrees. In the question, they are 90 quantities. So that means we need 90% of the circle graph.
So first let divide 90 by 100 which gives us 0.9.
Now let multiply 0.9 times 360 which gives us 324.

The hanger image below represents a balanced equation
Answer:
9.1 = a + 4
Step-by-step explanation:
Equations
If the hanger image represents a balanced equation, then the left and the right 'weights' on the hanger must be equal.
On the left side, there is a weight of 9.1, and on the right side, the weight is a+4. Balancing the hanger, we obtain the required equation:
9.1 = a + 4
Answer:
the equation would be 9.1 = a + 4

(4x2 - 17x3 + 9) - (x² + 9x + 23x² + 11)
0 - 19.73 – 25x2 – 12x – 3
- 10.x3 – 162x2 – 24x - 4
-17x3 - 20x2 – 9x 2
-16x3 – 243x2 – 12x – 3
Step-by-step explanation:
1) Your problem → (4x^2 - 17x^3 + 9) - (x^2 + 9x + 23x^2 + 11)
(-17x^3+4x^2+9)-(x^2+23x^2+9x+11)
=-17x^3+4x^2+9-x^2-23x^2-9x-11
=-17x^3+4x^2-x^2-23x^2-9x+9-11
=-17x^3-20x^2-9x-2
2) Your problem → 0 - 19.73 - 25x^2 - 12x - 3
=0-19.73-25x2-12x-3
=-25x^2-12x-22.73
3) - 10.x^3 – 162x^2 – 24x - 4
4) Your problem → 17x^3 - 20x^2 - 9x^2
=17x^3-20x^2-9x^2
=17x^3-29x^2
5) -16x^3 – 243x^2 – 12x – 3

Last year a poll of 1,000 voters conducted by the staff of Senator Chun found that 522 people approved of the job the senator was doing. This year, a new poll of 1,000 voters shows that 423 people approve of the senator's performance. Find the percent of change in the number of voters who approved of the senator's performance, and identify it as an increase or decrease.
A 19%, increase
B 23.4%; decrease
C 23.4%, increase
D 19%; decrease
Answer:
19% decrease
Step-by-step explanation:
First, find out how much it decreased by. 522 - 423 = 99. Then, since it decreased by 99/522 you find the percent this is equal to, which would be
18.96%. = about 19%
It is going down, so it's decreasing

Answer:
$0.25 per pound (answer B)
Step-by-step explanation:
We can use any two points to give the answer, by doing the slope of the graph, using the formula:
slope = (y2-y1)/(x2-x1)
Using the points (0, 0) and for example (16, 4)
we have:
slope = (4-0)/(16-0) = 4/16 = 1/4 = $0.25 per pound
which agrees with answer B.
Answer:
B) 0.25 pounds
Step-by-step explanation:
Go up the graph to 4 and div the pounds by 4 and you get 0.25! :)

Adinah and her friend planted a maple tree. The expression 3.1a + 5.2 can be used to find the height of the tree, in feet, after a years. How tall is the tree when a = 9
Answer:
33.1
Step-by-step explanation:
The tree would be 33.1 feet in 9 years.
the problem i put in my calculator is 3.1 * 9 + 5.2 , this is because if there is no sign indicating to add, subtract ect. you will multiply
The variables x and y vary directly. Use the values to find the constant of proportionality, k. Then write an equation that relates x and y. Write any fractions in simplest form.
y=20; x=12
k=
y=
Answer:
y=(5/3)x
Step-by-step explanation:
Since y varies directly with x, then the constant of proportionality is equal to k=y/x. Since y/x=20/12=5/3, then k=5/3. This means the equation to relate x and y is y=(5/3)x

Algebraically solve the following system of equations.
(x+2)2+(y-3)2=16
x+y-1=0
Answer:
[tex](-2-2\sqrt{2},3+2\sqrt{2})\,,\,(-2+2\sqrt{2},3-2\sqrt{2})[/tex]
Step-by-step explanation:
Given:
[tex](x+2)^2+(y-3)^2=16\\x+y-1=0[/tex]
To find: value of [tex]x,y[/tex]
Solution:
[tex](x+2)^2+(y-3)^2=16\,\,\,...(i)\\x+y-1=0\,\,\,(ii)[/tex]
From (ii),
[tex]x=1-y[/tex]
Put this value of [tex]x[/tex] in (i)
[tex](1-y+2)^2+(y-3)^2=16\\(3-y)^2+(y-3)^2=16\\(y-3)^2+(y-3)^2=16\\2(y-3)^2=16\\(y-3)^2=8[/tex]
[tex]y-3=[/tex] ± [tex]\sqrt{8}[/tex] = ± [tex]2\sqrt{2}[/tex]
[tex]y=3[/tex] ± [tex]2\sqrt{2}[/tex]
At [tex]y=3[/tex] + [tex]2\sqrt{2}[/tex] ,
[tex]x=1-(3+2\sqrt{2})=1-3-2\sqrt{2}=-2-2\sqrt{2}[/tex]
At [tex]y=3-2\sqrt{2}[/tex] ,
[tex]x=1-(3-2\sqrt{2})=1-3+2\sqrt{2}=-2+2\sqrt{2}[/tex]

In the graph above, what's the distance between (5, –2) and (5, 3)?
Answer:
5
Step-by-step explanation:
To find the distance between two points, subtract the two values and find the absolute value. So in this question, our equation would be |-2-3| which equals |-5| which then solves to 5.
Write an equation in slope intercept form that is perpendicular to 3x + 2y equals 12 and passes through the point (1,2)
Answer:
The equation is y = (2/3)x + (4/3).
Step-by-step explanation:
First, you have to change the equation into slope-intecept formula to find its gradient (slope) :
[tex]3x + 2y = 12[/tex]
[tex]2y = - 3x + 12[/tex]
[tex]y = - \frac{3}{2}x + 6[/tex]
Given that when a line is perpendicular to the other line, their slope value multiplied, will form -1. Next, we have to find the slope for line :
[tex]m1 \times m2 = - 1[/tex]
[tex] - \frac{3}{2} \times m2 = - 1[/tex]
[tex]m2 = - 1 \div - \frac{3}{2} [/tex]
[tex]m2 = \frac{2}{3} [/tex]
Lastly, we have to subatitute the x and y values into the equation, to find its intercept value :
[tex]y = \frac{2}{3}x + b[/tex]
[tex]let \: x = 1,y = 2[/tex]
[tex]2 = \frac{2}{3} (1) + b[/tex]
[tex]b = 2 - \frac{2}{3} [/tex]
[tex]b = \frac{4}{3} [/tex]
[tex]y = \frac{2}{3} x + \frac{4}{3} [/tex]
