I really need help on this question! Thank you!
Answer:
A
Step-by-step explanation:
We know the following:
[tex]OE=5\\\\FG=4\\\\EF=8\\\\[/tex]
so the segment EF is equal to
[tex]EF=EG+GO+OF\\\\[/tex]
and here we can do a trick :)
[tex]EF=(EG+GO)+GO+(OF+OG)-2GO\\\\[/tex]
you see it's the same
[tex]EF=EO-GO+FG\\\\[/tex]
now we plug the values given
[tex]8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1[/tex]
so it's option A
Rewrite the expression in the form 5^n
(5^-8) (5^-10)
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

What is the slope of the line through (-4,2)(−4,2)left parenthesis, minus, 4, comma, 2, right parenthesis and (3,-3)(3,−3)left parenthesis, 3, comma, minus, 3, right parenthesis? Choose 1 answer: Choose 1 answer: (Choice A) A \dfrac57 7 5 start fraction, 5, divided by, 7, end fraction (Choice B) B \dfrac75 5 7 start fraction, 7, divided by, 5, end fraction (Choice C) C -\dfrac57− 7 5 minus, start fraction, 5, divided by, 7, end fraction (Choice D) D -\dfrac75− 5 7
Answer:
-5/7
Step-by-step explanation:
slope = (difference in y)/(difference in x) = (-3 - 2)/(3 - (-4)) =
= -5/(3 + 4) = -5/7
Answer: -5/7
Answer:
-5/7 that is the answer

A lost turtle - swimming 13 feet below the surface of the water - begins to ascend at 0.5 foot per second. In hopes of (harmlessly) capturing the turtle, a diver jumps into the water to a depth of 4 feet before descending at a rate of 0.25 foot per second.
a) Write an equation to model the position of the turtle at any given time.
b) Write an equation to model the position of the diver at any given time.
c) After how long will the diver be able to catch the turtle?
d) At what depth will the diver be able to catch the turtle?
9514 1404 393
Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.

David went for a run in his town.
• He ran from his house to the school, which is 1.2 miles.
• Then he ran 3 laps around the school track. Each lap is 0.25 miles.
• Then he ran halfway to the gas station. The distance from the school track to the gas station is 2.68 miles
Finally he ran straight home, which is 0.49 miles.
What is the total distance David ran?
8x + 3 (3 - x) = 34
A. x = 5
B. x = 2
C. x = 8
D. x = 4
Answer:
A. x=5
Step-by-step explanation:
8x+3(3-x)=34
We move all terms to the left:
8x+3(3-x)-(34)=0
We add all the numbers together, and all the variables
8x+3(-1x+3)-34=0
We multiply parentheses
8x-3x+9-34=0
We add all the numbers together, and all the variables
5x-25=0
We move all terms containing x to the left, all other terms to the right
5x=25
x=25/5
x=5
I think this is correct.
Answer: its A; x=5
Step-by-step explanation:
8x+3(3-x)=34
distribute the 3 through the parentheses
8x+9-3x=34
then add the like terms
5x+9=34
subtract the 9 to the 34
you shoud get
5x=25
then divide the 5 on both sides and you get your answer of x=5

Answer:
70
Step-by-step explanation:
The % itself stands for a ratio of 100, so 70% would be 70/100
Answer:
70/100
Step-by-step explanation:
This is because if you break down a percantage, it is just a fraction or decimal. The numerator is 70 because 70/100 = 0.7
0.7 is just the decimal form of the percent "70%"
