Answer:
AC = 24
Step-by-step explanation:
First you want to set up the equation to find what x equals which is AB + BC = AC
12x - 20 = x + 6 + 5x - 4
Then combine like terms and solve.
12x - 20 = x + 6 + 5x - 4
12x - 20 = 6x +2
+20 +20
12x = 6x + 22
-6x -6x
6x = 22
x = 11/3 or 3 2/3
Then plug in x to the AC equation.\
12(11/3) - 20
44-20
AC = 24

The length of a field in feet is a function f(n) of the length n in yards. Write a function rule for this situation.
A.f(n) = 12n
B.f(n)=1/3n
C.f(n)=n/12
D.f(n) = 3n
Answer:
D.f(n) = 3n
Step-by-step explanation:
The function rule for this given situation is shown below;
Given that
The length of the field in feet would be f(n) of the length n in yards
Now as we know that
1 yard = 3 inches
So
f(n) = 3n
Hence, the option d is correct

The ratio of salamanders to frogs is 6 to 7. If there are 9 salamanders, how many frogs are there?
Answer
10
Step-by-step explanation:
salamander:frog
6:7
start by setting up the ratios as fractions and using x as the variable.
[tex]\frac{6}{7}[/tex]=[tex]\frac{9}{x}[/tex]
next cross multiply.
6x=63

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°
how do I resolve this?
Answer:
32
Step-by-step explanation:
20+2+4+6

The measure of one base angle of an isosceles triangle is 35 degrees. What is the measure of the vertex angle?
Answer:
110 degrees
Step-by-step explanation:
The measures of the two base angles of an isosceles triangle are the same so 180 - 2(35) = 110 which is the vertex angle.
What should be added to both sides of the equation below to complete the square?
x?
+ 6x = -8
O-4
O-2
O-9
09
Answer:
Step-by-step explanation:
x² + 6x = 8
Coefficient of the x term: 6
Divide it in half: 3
Square it: 3²
Add 3² to both sides of the equation to complete the square and keep the equation balanced:
x² + 6x + 3² = 8 + 3²
(x+3)² = 17

Find the arc length of the partial circle.
Either enter an exact answer in terms of it or use 3.14 for 4 and enter your answer as a decimal.
units
Answer:
3.14 times 4 equal 12.56
The requried arc length of the partial circle with a radius of 4 and a central angle of 270 degrees is 6π units, or approximately 18.85 units if using 3.14 as an approximation for π.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
Here,
When the central angle of a circle is given in degrees, we can use the formula for arc length:
arc length = (Ф/360) x 2πr
Here, the radius is given as 4, and the central angle theta is 270 degrees. Substituting these values into the formula,
arc length = (270/360) x 2π(4)
arc length = (3/4) x 2π(4)
arc length = (3/4) x 8π
arc length = 6π
Therefore, the arc length of the partial circle with a radius of 4 and a central angle of 270 degrees is 6π units, or approximately 18.85 units if using 3.14 as an approximation for π.

In a scale drawing of an airplane, 1 inch represents 7 feet.
Scale
Answer:
35 ft
Step-by-step explanation:
if
1=7 then
5x7=35/1= 35
(a) the length of real airplane is 35feets (b) the wingspan of the airplane in the scale drawing is 9inches
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
Given;
1in= 7feet
length of real airplane =5inches
the wingspan of the airplane in the scale drawing= 63feet
Length of real airplane
5 x 7= 35feets
Wingspan of airplane in drawing
63/7= 9inches
Therefore, the answers after conversions are 35feets and 9inches
