Two angles of a quadrilateral measure 125° and 35°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answers
Answer:
120° and 80°
Step-by-step explanation:
quadrilateral = 360°
125° + 35° = 160°
360° - 160° = 200°
3/5 of 200° = 120°
200° - 120° = 80°
Answer:
Step-by-step explanation:
Finding the missing angles of quadrilateral:
Ratio of other two angles = 3 : 5
Other two angles are 3x , 5x
Sum of all angles of quadrilateral = 360
125 + 35 + 3x + 5x = 360
Combine like terms
160 + 8x = 360
Subtract 160 from both sides
8x = 360 - 160
8x = 200
Divide both sides by 8 to isolate x
x = 200/8
x = 25
5x = 5*25 = 125
3x = 3*25 = 75
The other two angles are 125° , 75°

Step-by-step explanation:
d = 18 cm

Because the points have the same x-coordinate, the distance between the two points is a vertical distance. The distance from the ordered pair (−4,−3) to the x-axis is the absolute val
ue of it's y-coordinate. What is the absolute value of the y-coordinate in the ordered pair (−4,−3)?
Answers
Answer:
3
Step-by-step explanation:
The distance from a point to the x axis is the absolute value of its y-coordinate as it mentioned in the problem.
So take the y-coordinate, -3, and find the absolute value by making the number positive. Absolute values are always positive.
Which is an equation of the line that passes through the points (5, 2) and (10, -3)? HELP
Answers
Answer:
y = − x + 7
Step-by-step explanation:
let D be the line that passes through the points (5, 2) and (10, -3)
Then D has an equation of the form D: y = mx + p
Now we need to find m and p in order to be able to write the equation of the line D:
[tex]m = \frac{2-(-3)}{5-10} = \frac{5}{-5} = -1[/tex]
Since the point (5 , 2) lies on the line D then :
2 = -1 × (5) + p
then
2 = -5 + p
then
p = 2 + 5
= 7
then
p = 7
Conclusion:
Since m = -1 and p = 7
then
[tex]D : y = -x + 7[/tex]

Alyssa is getting gas for her car. Her car’s 15-gallon tank has 1/5 a tank of gas left. If gas costs $2.699 per gallon, how much will she pay for gas, rounded to the nearest cent?
Answers
Answer:
$32.39
Step-by-step explanation:
She has a 15-gallon tank and it has 1/5 a tank of gas left (so about 3/15)
Because she needs to refill it and already has 1/5, she'll only need to pay for 4/5 a tank of gas (12/15).
So the equation should be 12 times $2.699.
12 × 2.699 = 32.388
Then, round to the nearest cent.
32.388 = $32.39

help! p(x) = 4x^4 - 10x^3 + 8x - 1
x = 8
Answers
Answer:
p(8) = 11,327
Step-by-step explanation:
Hey there!
In order to find the answer, all we need to do is subtitute the x values for 8
After substituting, the equation will look like this:
[tex]p(8)=4(8)^4-10(8)^3+8(8)-1[/tex]
Now we simplify
8 to the power of four is 4096 and when you multiply that by 4, you get 16384
8 to the power of 3 is 512 and when you multiply that by -10, you get -5120
8 times 8 is 64
And then there is -1
Now all we have to do is combine all the answers together for one final answer
16384-5120+64-1 is equal to 11327
So the output of this function when you input 8 is 11,327
