Answer:
x = 32°
y = 17°
Step-by-step explanation:
Let's look at the bottom triangle since it has two angles.
62° + 75° = 137°
180° - 137° = 43°
The missing angle measure is 43°. Since the two angles make up a straight line,
(4x + 9)° + 43° = 180
4x + 52° = 180°
4x = 128°
x = 32°
The angle measuring 62° is a vertical angle so the angle opposite it is also 62°. The missing angle for that triangle would 40° because 180° - 140° = 40°.
62° + 40° = 102°
180° - 102° = 78°
(5y - 7)° = 78°
5y = 85°
y = 17°
Hope that helps.

b. cubic centimeters.
c. kilograms per liter.
d. grams per cubic centimeter.
Answers
Answer:
d. grams per cubic centimeter
Step-by-step explanation:
The unit for density is g/cm^3 because the formula for density is mass divided by volume. The standard unit for mass is grams, and volume is cm^3. So by dividing the two numbers, the unit becomes both units divided.
Can someone plz help me asap!

Answer:
The angle across the given measurements are the same. So there will be a 27 degrees across from the other 27 degrees. The straight line is 180 degrees, so do 180-27=153. The means the other 2 angles are 153 degrees. The other one is the same, but with different measurements. 180-35=145
Step-by-step explanation:
Let the angle adjacent to ∠27° be x .
[tex]∠x + 27 = 180° \: ( \: linear \: pair \: )[/tex]
[tex]x = 180 - 27 \\ ∠x = 153°[/tex]
Let the angle opposite to ∠27° be y .
[tex]∠y = ∠27° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle adjacent to ∠y ( 27°) be w .
[tex]w + ∠27° = 180° \: ( \: linear \: pair \: ) \\ w = 180 - 27 \\ ∠w = 153°[/tex]
Let the angle opposite to ∠35° be p .
[tex]∠p = ∠35° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle adjacent to ∠35° be a .
[tex]∠a + 35° =180 ° \: ( linear \: pair ) \\ a = 180 - 35 \\ ∠a = 145°[/tex]
Let the angle opposite to ∠35° be t .
[tex]∠t = 35° \: ( \: vertically \: opposite \: angles \: )[/tex]
Let the angle opposite to ∠145° be o .
[tex]∠o \: = 145° \: ( \: vertically \: opposite \: angles \: )[/tex]
When lava is expelled from a volcano, it temperature may vary from 700 degrees Celsius to 1200 degrees Celsius. Write an absolute value equation that represents the minimum and maximum temperatures of lava. Use x to represent the temperature.
Equation:__
Answers
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C

If 6x + 4 = 11x - 21, what is the value of x?
Answers
Answer:
x = 5
Step-by-step explanation:
11x - 6x = 4 + 21
5x = 25 (÷5)
x = 5
Explanation: 6x + 4 = 11x - 21
1). Subtract 4 from both sides and you will get 6x = 11x -25.
2). Subtract 11x from both sides and you should get -5x = -25.
3). Divide the -5 with -25 to get x alone and you should get X=5!
Check your work:
6(5) + 4 = 34 & 11(5) - 21 = 34
34=34.
the two angles are supplementary if a=19x+3 and b= 21x +17 solve for x and find the measure of each angle
Answers
Answer:
x = 4
a = 79
b = 101
Step-by-step explanation:
Supplementary means equal to 180° after all angles are added together.
a=19x+3
b= 21x +17
(19x+3) + (21x +17) = 180
19x + 3 + 21x + 17 = 180
40x + 20 = 180
40x = 160
x = 4
a = 19(4)+3 = 79
b = 21(4) +17 = 101

Evaluate the piecewise defined function at the indicated values.

f(0) = 0
f(25) =
Answers
Given:
Consider the piecewise function is
[tex]f(x)=\left \{\begin{matrix}x^2+4x,\text{ if } x\leq -1\\ x, \text{ if }-1<x\leq 1\\-1,\text{ if }x>1\end{Matrix}\right.[/tex]
To find:
The value of the function at indicated values.
Solution:
We know that, [tex]-2,-\dfrac{3}{2},-1[/tex] are less than or equal to -1. So, for these values the function is [tex]f(x)=x^2+4x[/tex].
For x=-2,
[tex]f(-2)=(-2)^2+4(-2)[/tex]
[tex]f(-2)=4-8[/tex]
[tex]f(-2)=-4[/tex]
Similarly,
For [tex]x=-\dfrac{3}{2}[/tex].
[tex]f(-\dfrac{3}{2})=(-\dfrac{3}{2})^2+4(-\dfrac{3}{2})=-\dfrac{15}{4}[/tex]
For [tex]x=-1[/tex].
[tex]f(-1)=(-1)^2+4(-1)=-3[/tex]
We know that, 0 is lies between -1 and 1. So, for this values the function is [tex]f(x)=x[/tex].
For x=0,
[tex]f(0)=0[/tex]
We know that, 25 is greater than 1. So, for this values the function is [tex]f(x)=-1[/tex].
For x=25,
[tex]f(25)=-1[/tex]
Therefore, the required values are, [tex]f(-2)=-4, f(-\dfrac{3}{2})=-\dfrac{15}{4},f(-1)=-3,f(0)=0,f(25)=-1[/tex].
