Answer:
bottom right is 65 degrees, bottom left is 25 degrees, top is 90 degrees. x=12
Step-by-step explanation:
the angles if a triangle always add up to 180, lets make an equation
2x+1+5x+5+90=180
^^ we know that's 90 because there is a square for the angle, which means it's 90 degrees.
7x+96=180
7x=84
x=12
2(12)+1
25
5(12)+5
65

Answer: It is located in quadrant III (3) of the coordinat plain
Step-by-step explanation:
You can use the negative numbers to find their placement. if there are no negative numbers, it’s in quadrant I (1). If there‘s a negative number for the Y-coordinate, then it’s in quadrant II (2). If there are 2 negative numbers, it’s in quadrant III (3). And if there’s a Negative number for the X-coordinate, it’s in quadrant IV (4).

Which equation represents the line that is perpendicular to y=1/5 and passes through (-4,-3)?
A. x= -4
B. x= -3
C. y= -5
D. y= -3
Answers
Answer:
The required line's equation is x=-4. Option A.
Step-by-step explanation:
This is more conceptual than a numerical problem.
We have the line y=1/5 and want to find a perpendicular line that passes through (4,-3).
The line y=1/5 is a horizontal line with slope 0. The perpendicular line would have an infinity slope and it would make it impossible to use the regular procedure to find it.
Instead, we realize that a perpendicular line to a horizontal line is a vertical line.
All vertical lines have the equation x = h, where h is the x-component of the point it passes through.
Now we only have to see the x-component of the point (-4,-3) and write our solution:
The required line's equation is x=-4. Option A.

PLEASE HELP 15 POINTS The sum of the measures
of seven out of ten angles
in a decagon is 1086°. If the
three remaining angles are
equal in measure, what is the
measure of each angle?
Answers
Answer:
118
Step-by-step explanation:
1440-1086= 354
354/3=118
The measure of each angle is 118 degrees
The given parameters are:
Shape: DecagonSeven angles add up to 1086The remaining three angles are congruentThe sum of interior angles of a decagon is 1440.
Let each of the remaining three angles be represented with x.
So, we have:
[tex]1086 + 3x = 1440[/tex]
Collect like terms
[tex]3x = 1440 - 1086[/tex]
[tex]3x = 354[/tex]
Divide both sides by 3
[tex]x = 118[/tex]
Hence, the measure of each angle is 118 degrees

Answers
Complete question :
Larry Mitchell invested part of his $32000 advance at 4% annual simple interest and the rest at 9% annual simple interest. If his total yearly interest from both accounts was 2430, find the amount invested at each rate. The amount invested at is $ nothing. The amount invested at is $ nothing.
Answer:
Investment at 4% = $9000
Investment at 9% = $23,000
Step-by-step explanation:
Given that :
Total investment = 32000
Let;
amount invested at 4% = a
amount invested at 9% = 32000 - a
Total interest earned = 2430
Simple interest = principal * rate * time
Investment at 4%:
(a * 0.04) + [(32000 - a) * 0.09] = 2430
0.04a + 2880 - 0.09a= 2430
-0.05a + 2880 = 2430
-0.05a = 2430 - 2880
-0.05a = - 450
a = 9000
Hence,
Investment at 4% = $9000
Investment at 9% = $32,000 - $9000 = $23,000

Answers
c=4

I have attached the worked out problems as well hope it helps!
x – 7 = 4 + 10 (x=21)
x−7=4+10
x+−7=4+10
x−7=(4+10)(Combine Like Terms)
x−7=14
x−7=14
Step 2: Add 7 to both sides.
x−7+7=14+7
x=21
---------------------------------------------------
12−c=8 (c=4)
12+−c=8
−c+12=8
Step 2: Subtract 12 from both sides.
−c+12−12=8−12
−c=−4
Step 3: Divide both sides by -1.

-42=20=-2=13x (x=−2
Simplifying
-42 + 20 = 2x + 13x
Combine like terms: -42 + 20 = -22
-22 = 2x + 13x
Combine like terms: 2x + 13x = 15x
-22 = 15x
Solving
-22 = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
-22 + -15x = 15x + -15x
Combine like terms: 15x + -15x = 0
-22 + -15x = 0
Add '22' to each side of the equation.
-22 + 22 + -15x = 0 + 22
Combine like terms: -22 + 22 = 0
0 + -15x = 0 + 22
-15x = 0 + 22
Combine like terms: 0 + 22 = 22
-15x = 22
Divide each side by '-15'.
x = -1.466666667
Simplifying
x = -1.466666667
Ferdinand Freight Company charges a flat rate of $200 plus $0.75 per pound to transport freight in
the metro area. This cost is represented by the function below where w is the weight of the freight
in pounds and c(w) is the cost given the weight of the freight
c(w) = 200+ 0.750
Answers
Answer:
$1325
Step-by-step explanation:
c(w) = 200 + 0.75w
c(1500) = 200 + 0.75(1500)
c(1500) = 200 + 1125
c(1500) = 1325
