Answer:
6.67 seconds
Step-by-step explanation:
Benny = 15 - 0.5s
Juan = 10 + 0.25
Where,
s = number of seconds
Equate
15 - 0.5s = 10 + 0.25s
15 - 10 = 0.25s + 0.5s
5 = 0.75s
s = 5/0.75
= 6.66667 seconds
Approximately 6.67s
Passing through (-2,8) and perpendicular to y=2x+5
Answer: y=-1/2x+7
Step-by-step explanation:
1-
slope is opposite of 2 so -1/2
2-
Plug in the point to the new slope to solve for the b value
8=(-1/2)(-2)+b
3-
Solve for b
7=b
Answer-
y=-1/2x+7
What is 45% written as a fraction in simplest form?
Answer: The answer is 9/20

PX,PY, and PZ are the perpendicular bisectors of ARST. Find PS and XT.
Answer:
PS = 82.8 ; XT = 46.1
Step-by-step explanation:
PZ = [tex]\sqrt{TP^2 - TZ^2}[/tex] = √(82.8² - 76.5²) = √1003.59
TZ = SZ = 76.5
PS = [tex]\sqrt{PZ^2 +SZ^2}[/tex] = √(1003.59 + 5852.25) = 82.8 units
XT = RX = 46.1 units
Simplify this expression.

PLEASEEEEE HELPPPP BEST ANSWER WILL GET BRAINLIEST LESTSSS GOOO.
Answer:
Perimeter of the given triangle is :---
[tex](5w) + (7w - 2) + (9w + 5) \\ = 5w + 7w - 2 + 9w + 5 \\ = \boxed{ 21w + 3}✓[/tex]
(21w+3) is the right answer.which graph could be used to show the situation described?
the temperature decreases by 0.5 degrees every hour.
Answer:
Option (2) [Graph on the top right]
Step-by-step explanation:
To find the temperature decrease by 0.5 degrees every hour we will find the slopes of the lines given in every option.
Option (1) [Top left graph]
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-20}{2}[/tex]
= -10
Option (2) [Top right]
Slope = [tex]\frac{-2}{4}[/tex]
= -0.5
Option (3) [Bottom left]
Slope = [tex]\frac{-2}{2}[/tex]
= -1
Option (4) [Bottom right]
Slope = [tex]\frac{-60}{5}[/tex]
= -12
Therefore, Graph given in option (2) will represent the decrease in temperature by 0.5 degrees per hour.
