Amber trains for 1h one day. She runs for 10 min, walks for 5 min, runs for 15 min, and walks for 5 min. Her running time increases by 5 min each interval, but she always walks for 5 min. Use fractions of one hour. Write an addition equation that represents Amber's total running time. Find her total running time.
Answers
Answer:
Part A
The addition equation that gives Amber's total running time is presented as follows;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr
Part B
Amber's total running time = 5/6 hr = 50 minutes
Step-by-step explanation:
Part A
The given parameters are;
The time duration Amber first ran = 10 min = 1/6 hr
The time duration Amber walks in between = 5 min = 1/12 hr
The increase in the number of minutes Amber runs in subsequent times = 5 min = 1/12 hr
Therefore, the Amber's total time is given as follows;
1/6 hr + 1/12 hr + (1/6 + 1/12) hr + 1/12 hr + x hr = 1 hr
7/12 hr + x hr = 1 hr
x hr = 1 hr - 7/12 hr = 5/12 hr
x = 5/12
Therefore, her total running time is given by the following addition equation;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr
Part B
Therefore her total running time is given as follows;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr = 5/6 hr = 50 minutes

A triangle has a 62° angle and a right angle. What is the measure of the third angle?
Answers
Answer:
Measure of the third angle is 28°
Step-by-step explanation:
A Triangle has three angles in total which when summed up equal to 180 degrees. Now the information in the question is that the first angle is 62° the second angle is a right angle which means it is a 90° angle and we need the third angle, and when all of this when added equals 180° So,
We let the third angle be called x.
[tex]62 + 90 + x = 180\\\\152+x=180\\\\x=180-152\\\\x=28[/tex]
So our third angle is 28°
Step-by-step explanation:
Sum of angles on a straight line = 180°
Let the third angle be x°
62° + 90° + x° = 180°......(Sum of angles on a straight)
152° + x. = 180°
x°. = 180°-152°
x° =28°

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wraps cost $1.00 and the chicken wraps cost $1.50. Today they made $149.00 from the 105 wraps sold. How many wraps sold were vegetarian?
Answers
Answer:
17 wraps
Step-by-step explanation:
Given data
let the number of vegetarian wraps be x
and chicken wraps be y
so
x+1.5y= 149------------1
and
x+y= 105----------------2
the systems of equation for the problem is
x+1.5y= 149
x+y= 105
from 2
x= 105-y
put this in 1
105-y+1.5y= 149
105-0.5y= 149
-0.5y= 149-105
-0.5y=44
y= 44/0.5
y= 88
put y = 88 in 2
x+88= 105
x= 105-88
x= 17

Answers
find the values of x and y.
Answers
Answer:
x = 20, y = 70
Step-by-step explanation:
The angle adjacent to 40° is 180° - 40° = 140°
Since the triangle on the right has 2 congruent sides then it is isosceles and its base angles are congruent, both x
2x + 140 = 180 ← sum of 3 angles in triangle
Subtract 140 from both sides
2x = 40 ( divide both sides by 2 )
x = 20
------------------------------------------
The angle inside the triangle on the left is 90° - 20° = 70° , then
y = 180 - (40 + 70) = 180 - 110 = 70

Find the degree measure of each angle in the triangle. Giving brainly
Answers
Answer:
∠ I = 39°, ∠ J = 51°, ∠ K = 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the3 angles and equate to 180
3x + 21 + 5x + 21 + 90 = 180, that is
8x + 132 = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
Then
∠ I = 3x + 21 = 3(6) + 21 = 18 + 21 = 39°
∠ J = 5x + 21 = 5(6) + 21 = 30 + 21 = 51°
∠ K = 90°
What are the zeros of f(x) = x2 + x – 30?
A. x = –6 and x = 5
B. x = –5 and x = 6
C. x = –15 and x = 2
D. x = –2 and x = 15
Answers
Answer:
Answer A is correct. (x + 6)(x - 5) = x^2 + x - 30.
Step-by-step explanation:
Note that -30 = (-5)(6) and (5)(-6). This quadratic can be factored easily:
x^2 + x - 30 = (x + 6)(x - 5) is correct because 6x - 5x = x, the middle term of x^2 + x - 30.
Setting each factor equal to zero, one by one, we get:
x + 6 = 0 => x = -6, and x - 5 = 0 => x = 5
Answer A is correct.
