Answer:
Step-by-step explanation:
Angle A and 50 will combined have an angle of 180
Angle A = 180-50
Angle C is opposite of angle A and both will be equal. Same with Angle B and it's opposing Angle.
You got this!
The student would have to score 100% on their next test to brung their average up to 90. Here is why;
90+84+86=260
(260+?)/4=90
(260+100)/4=90
360/4=90
This is done to get the mean (or average) of a group of numbers by adding all the numbers and dividing by the amount of numbers you added together. Here it is divided by 4 because of the three tests he has taken and the test he will take.
Imagine right triangle PHF, where P - park, H - home and F - football field, then PH, PF are legs and HF is hypotenuse . Denote point L to be library. You know that point L lies on the segment FH and FL=8, LH=2. Also you know that PL is an altitude to the hypotenuse.
Use the property of altitude drawn from the vertex of right angle to the hypotenuse (the length of the altitude is geometrical mean between legs' projections onto hypotenuse):
mi.
This means that the distance between park and libriry is 4 miles.
Consider right triangle PLF ( angle L is right angle and PF - hypotenuse). By the Pythagorean theorem,
mi. The distance between park and football field is 
miles.
Answer: the distance between park and libriry is 4 miles and the distance between park and football field is miles.
Answer:
The coefficient of k is -6
Step-by-step explanation:
Let x = -2
Let y = 12
y = kx
12 = k(-2)
k =12÷(-2)
= -6

<span>
-- "Two hundred and three thousandths"
means' ' 2.003 '.
-- "Two hundred three thousandths" would mean ' 0.203 '.
How can you tell the difference?
The difference is the 'and'.</span> "And" means 'decimal point'.
' 678 ' is read as "six hundred seventy eight", with no 'and'.
' 40.06 ' is read as 'forty and six hundredths'.
' 0.46 ' is read as ' forty-six hundredths'.
