Answer:
3.5 hours
Step-by-step explanation:
It is given that,
Velocity of first car, v = 20 mph
Velocity of second car, v' = 60 mph
They are moving in opposite direction. Their relative speed is given by :
V = 20 mph + 60 mph = 80 mph
Distance, d = 280 miles
So,
[tex]t=\dfrac{d}{V}\\\\t=\dfrac{280}{80}\ h\\\\t=3.5\ h[/tex]
Hene, they will be 280 mile apart in 3.5 hours.

Jonathan will run a 614-mile relay with 4 other team members, where each team member runs an equal distance. How many miles will Jonathan run?
Answer: Jonathan will rum [tex]1\dfrac14\text{ mile}[/tex] .
Step-by-step explanation:
Given: Total distance to run =[tex]6\dfrac14[/tex] miles [tex]=\dfrac{25}{4}[/tex] miles
Total members = 1+4 = 5
if each member runs equal distance.
Then, each member will run = [tex]\dfrac{\text{Total distance}}{\text{Total members}}[/tex]
[tex]=\dfrac{\dfrac{25}{4}}{5}\\\\ \lim_{n \to \infty} a_n =\dfrac{25}{4\times5}\\\\=\dfrac{5}{4}\\\\ = 1\dfrac14 \text{miles}[/tex]
Hence, Jonathan will rum [tex]1\dfrac14\text{ mile}[/tex] .

each basket?
Three baskets contain three consecutive odd numbers of apples. There are 105 apples in total. How many apples are
Enter the numbers from least to greatest.
==================================
Explanation:
Consecutive integers are integers like 1,2,3,... or 6,7,8... so they are integers that follow one after another.
Consecutive odd integers are sequences like 3,5,7,... or 21,23,35... meaning they are odd integers following one after another as close as possible.
If x is some integer, then 2x is always even and 2x+1 is always odd
let 2x+1 be that first odd integer
adding on 2 leads to the next odd integer: (2x+1)+2 = 2x+3
adding on another 2 leads to the next one: (2x+3)+2 = 2x+5
The three expressions
2x+1
2x+3
2x+5
represents three consecutive odd integers. They must add to 105
(2x+1)+(2x+3)+(2x+5) = 105
(2x+2x+2x)+(1+3+5) = 105
6x+9 = 105
6x = 105-9
6x = 96
x = 96/6
x = 16
Meaning that
2x+1 = 2(16)+1 = 33 = first odd integer
2x+3 = 2(16)+3 = 35 = second odd integer
2x+5 = 2(16)+5 = 37 = third odd integer
As a check
33+35+37 = 105
which confirms the answer

Since 1/2 slope is perpendicular to the equation the slope is -2 which is the opposite of the reciprocal of 1/2.
Since the slope is -2, every time you go forward you go down 2.

Which are true if figure DEFG is reflected across the x-axis? Check all that apply.
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from G' to the x-axis will equal 2 units.
The perpendicular distance from D' to the x-axis will equal 8 units.
The orientation will be preserved.
Answer:
A,B,C
Step-by-step explanation:
If figure DEFG is reflected across the x-axis, the correct statements are:
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from D' to the x-axis will equal 8 units.
Options A, B, and E are the correct answers.
What is a reflection?There are two ways of reflection.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
D(0, 4) → D'(0, –4) - True.
Reflecting a point across the x-axis negates its y-coordinate.
E(–2, 0) → E'(–2, 0) - True.
Reflecting a point across the x-axis does not change its x-coordinate.
The perpendicular distance from G' to the x-axis will equal 2 units. - False. The perpendicular distance from G' to the x-axis will be the same as the perpendicular distance from G to the x-axis.
The perpendicular distance from D' to the x-axis will equal 8 units. - True.
The perpendicular distance from D' to the x-axis will be the same as the perpendicular distance from D to the x-axis, which is twice the distance between D and the x-axis.
The orientation will be preserved. - False.
Reflecting a figure across the x-axis will reverse the orientation of the figure.
Thus,
D(0, 4) → D'(0, –4) - True
E(–2, 0) → E'(–2, 0) - True
The perpendicular distance from D' to the x-axis will equal 8 units. - True.

Answer:
76
Step-by-step explanation:
angle FGH = 120, angle FGV = 44, and angles VGH and FGV add up to angle FGH. These are the givens. Since VGH + FGV = FGH, then FGH - FGV = VGH. That can be rewritten as 120 - 44 = VGH. 120 - 44 = 76, so VGH = 76

Answer:
y = 2x+4
Step-by-step explanation:
From the graph, we can tell that slope is 2 because if we go up 2 units up from (0,4) which is point Q and then go right 1 unit, the slope is 2. The y intercept is (0,4)
y = mx + b
m --> slope
b --> y-intercept
y = 2x+4

Which is the equation of a line that has a slope of -2/3 and passes through point -3 -1?
Answer: y= -2x/3 -3
Step-by-step explanation:
Substitute the x and y values from the given coordinate into the slope-intercept formula and solve for b
y = mx + b
-1 = -2/3(-3) + b
-1 = 2 + b
-1 -2 = b
-3 = b The y-intercept is -3
the equation: y = -2x/3 - 3

Answer:
The invert part of “invert and multiply” means to take the denominator of this big fraction, 1/4, and invert it. In other words, flip it on its head so its numerator becomes its denominator and vice versa. The inverse of 1/4 is therefore 4/1, or just 4.

Determine the value of X 12,9, 3
The value of x from the given proportion is 4.
The given numbers 12, 9 and 3 are proportions.
What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
To find the value of x:
So, 12:x::9:3
⇒ 12×3=x×9
⇒ 9x=36
⇒ x=36/9
⇒ x=4
Therefore, the value of x from the given proportion is 4.
