Answer: The average speed is 3m/s.
Step-by-step explanation:
We can define the average speed as the quotient between the total distance traveled in a given period of time, and that period of time,
Here we have that:
d = distance
t = time.
"A lioness hunting antelope runs a distance of 60 m in 15 s"
1) d = 60m, t = 15s
"Then she stops to survey the herd for 20 s"
We add 0 meters to the distance, and 20 seconds to the time.
2) d = 60m + 0m, t = 15s + 20s = 35s
"she trots for 25 s over 60 m around the edge of the herd."
we add 60m to the distance, and 25s to the time
3) d = 60m + 60m = 120m, t = 35s + 25s = 60s.
"Finally, the lioness races after the antelope, traveling 120 m in 20 s"
we add 120m to the distance and 20s to the time.
4) d = 120m + 120m = 240m, t = 60s + 20s = 80s.
Then the average speed of the lioness in that period of time is:
S = 240m/80s = 3m/s
Write an integer that represents a $3 loss.
Answer: -3 or -$3.
Step-by-step explanation:
First, the set of integer numbers is the set of all the whole numbers (negatives, zero, and positives).
We want to write a $3 loss, now, the most important part here is that we have a loss, so we must represent this with a negative number.
Then we can write this as:
"An integer that represents a $3 loss"
is -3 or -$3 (if we want to also respect the units)
Solve this equation 4+4|2x−1|=12.
Answer:
x=1.5 or3/4
Step-by-step explanation:
using bodmas
remove the bracket: 4+4=(2x-1)=12
4+8x-4=12
8x=12+4-4
8x=12
x=3/2 or 1.5

The standard form of the equation is 11x + 10y = -10.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given equation is y=-11/10x-1. The standard form of the equation can be written as,
y=-11/10x-1
10y = -11x - 10
11x + 10y = -10
Hence, the standard form of the equation is 11x + 10y = -10.

Can someone please help me with this. If you do the equation solve for F
2(x+4)= -5x+1
Some one please solve
Let's solve your equation step-by-step.
2(x+4)=−5x+1
Step 1: Simplify both sides of the equation.
2(x+4)=−5x+1
(2)(x)+(2)(4)=−5x+1(Distribute)
2x+8=−5x+1
Step 2: Add 5x to both sides.
2x+8+5x=−5x+1+5x
7x+8=1
Step 3: Subtract 8 from both sides.
7x+8−8=1−8
7x=−7
Step 4: Divide both sides by 7.

How do you evaluate 3x+8 when x=2?
Answer:
3x + 8 is equal to 14 when x = 2.
Step-by-step explanation:
To evaluate the expression 3x + 8 when x = 2, we simply subsititute the value of x into the expression. We can write this expression as the function:
f(x) = 3x + 8
And we can evaluate the function when x = 2 by simply plugging in the value 2 for x:
f(x) = 3x + 8
f(2) = 3(2) + 8
f(2) = 6 + 8
f(2) = 14
Hence, the expression 3x + 8 is equal to 14 when x = 2.
Cheers.

Step-by-step explanation:
use the properties of equality to show that the equation 6x + 3 = 27 is equivalent to the equation 2x = 8.
Answer:
Step-by-step explanation:
The equation 6x + 3 = 27 is equivalent to 2x = 8 because you can divide 8 by 2x to get X=4. To solve 6x + 3 = 27, you can subtract 3 to both sides of the equal sign to end up with 6x = 24, and from there you can divide 24 by 6x and also end up with X = 4. Both equations have the same answer.
how would I exactly resolve this
Answer:
m∠BFE = m∠BAF + m∠AFE
m∠BFE = 65º + 25º
m∠BFE = 90º
m∠AFC = m∠AFB + m∠BFC
m∠AFC = 65º + 45º
m∠AFC = 110º
m∠BFD = m∠BFC + m∠CFD
m∠BFD = 45º + 70º
m∠BFD = 115º
Use formulas d=rt. find t for r=48.3 m/h and d = 545.79 m.
(A) 26,362 h
(B) 497.49 h
(C) 0.09 h
(D) 11.3 h
Answer:
11.3
Step-by-step explanation:
Just plug in the known variables.
d = rt
d = 545.79
r = 48.3
545.79 = 48.3t
you need to get T alone
so divide
the end answer is 11.3
