Answer:
$76.80
Step-by-step explanation:
since you can't multiply to more easially get your answer you want to divid ethe $51.20 by 2 which = $25.60
he get's 25.60 for 40 miles
since 120 divided by 3 = 40 this means:
40x3=120
25.60x3=76.80
25.60+25.60=51.20+25.60= 76.80

Step-by-step explanation:
When Brooklyn runs the 400 meter dash, her finishing times are normally distributed with a mean of 76 seconds and a standard deviation of 3 seconds. Using the empirical rule, what percentage of races will her finishing time be between 70 and 82 seconds?
Using the Empirical Rule, it is found that her finishing time will be between 70 and 82 seconds in 95% of her races.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, the mean is of 76 seconds and the standard deviation is of 3 seconds, then:
76 - 2 x 3 = 70.
76 + 2 x 3 = 82.
Which means that values between 70 and 82 seconds are within 2 standard deviations of the mean, hence the percentage is of 95%.

The slope for 5 and 2
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
As we know, slope (m) is equal to tan θ for a straight line :
[tex]\qquad \tt\dashrightarrow \: m = \tan( \theta) [/tex]
[tex]\qquad \tt\dashrightarrow \: m = \dfrac{5}{2} [/tex]
So, we can say that it's a positive constant slope
Christina is 11 years older than caden. the sum of their ages is 35. how old is christina? how old is caden?
Answer:
Caden is 11 and Christina is 24.
Step-by-step explanation: IF we know the sum of their ages is 35, then we can do the math. 35 - 11 = 24
So this means we know two ages 11 and 24.
The only thing left to do is to figure out who's age is who's. We know that Christina is older so she has to be 24 year old and Caden would be younger.

What is the difference between 1.1 and 1.10
Answer:
They are the same.
Step-by-step explanation:
1.1 and 1.10 are both the same, actually. There is just an extra 0 at the end. For example, 2 and 2.0 are the same, because 0 is 0, and it doesn't change your answer. The 0 could go on as in 1.100000000 but it will still equal 1.1 .

The area of a circle is 4π ft². What is the circumference, in feet? Express your answer in terms of \piπ.
Answer:
4π ft.
Step-by-step explanation:
Area = π r^2 = 4π = π2^2
- so the radius is 2 ft,
and the circumfrence = 2 π r
= 2*π*2
= 4π ft.
The circumference of the circle is 4π feet.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
The formula for the area A of a circle with radius r is given by:
A = πr²
We are given that the area of the circle is 4π ft², so we can set up the following equation:
4π = πr²
Dividing both sides by π, we get:
r² = 4
Taking the square root of both sides, we get:
r = 2
The circumference C of a circle with radius r is given by:
C = 2πr
Substituting r = 2, we get:
C = 2π(2) = 4π
Therefore,
The circumference of the circle is 4π feet.

find m<1.
A. 30°
B. 32°
C. 34°
D. 36°
Answer:
B. 32°
Step-by-step explanation:
Finding ∠S and ∠R
∠S = 58°∠S = ∠R (Isoceles trapezoid)⇒ ∠R = 58°Similarly, ∠P = ∠Q (same reason as above)
Applying the Angle Sum Property of Quadrilaterals,
∠P + ∠Q + ∠R + ∠S = 360°2∠P + 2∠S = 360°∠P + ∠S = 180°∠P = 180° - 58°∠P = 122° = ∠QFinding the missing angles of the triangle

Please can u look at the following
Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x+3) = x - 4
==> distribute the 2
2x + 6 = x - 4
==> add 4 to both sides
2x + 10 = x
==> subtract 2x from both sides
10 = -x
==> divide both sides by -1
x = -10
b)
4(5x - 2) = 2(9x + 3)
==> distribute the 4 and 2
20x - 8 = 18x + 6
==> add 8 to both sides
20x = 18x + 14
==> subtract 18x from both sides
2x = 14
==> divide both sides by 2
x = 7
