The cost of 94 training sessions is $1681.3.
A unit means one thing. A unit rate means the rate of something. Write this as a ratio with a denominator of 1. For example, if you ran 70 meters in 10 seconds, you ran an average of 7 meters in 1 second. A ratio of 70 yards in 10 seconds and 7 yards in 1 second are both rates, but 7 yards in 1 second is a unit rate. The unitary method is a method of finding the value of one unit and then finding the value of the required number of units.Suppose you go to the market to buy six apples. The shopkeeper told you that he sells 10 apples for 100 rupees. In this case, the apple is the unit and the apple price is the value.
62 training sessions for $1109
1 session = 1109/62
94 sessions = (1109/62) * 94
= $1681 .3

Two trains leave towns 900 miles apart at the same time and travel toward each other. One train travels 20mi/h slower than the other. If they meet in 6 hours, what is the rate of each train?
Answer:
Hello,
Step-by-step explanation:
The time they travel is t=6 hours
v is rate of the fastest train
v-2 the slower one.
v*t+(v-20)*t=900
2vt-20t=900
12v-120=900
12v=900+120
v=1020/12
v=85 (mi/h)

The Density of the given plank with dimensions is; 33.82 kg/m³
How to calculate the density of an Object?We are given;
Length of plank = 2.3 meters
Width of plank = 30 cm = 0.3 m
Height of Plank = 3 cm = 0.03 m
Mass of plank = 0.7 kg
Now, formula for density = mass/volume
Volume of the plank is gotten from the formula;
Volume = Length * width * height
V = 2.3 * 0.3 * 0.03
V = 0.0207 m³
Thus;
Density = 0.7/ 0.0207
Density = 33.82 kg/m³
Thus, we can conclude that the Density of the given plank with dimensions is 33.82 kg/m³

the length of a rectangle is 6 m longer than its width. of the perimeter of the rectangle is 36 m, find its area
The length of a rectangle is 6 m longer than its width. of the perimeter of the rectangle is 36 m, its area is 72 m².
Any polygon's area is the amount of space it takes up or encloses. The amount of square units that make up the polygon. Because the area is a two-dimensional object, it has both length and width. Typically, the area is expressed in square meters, square feet, or square inches. Acres, hectares, and square kilometers are used to measure the size of larger shapes like cities and farms.
Let l be the length of the rectangle
And w be the width of the rectangle.
Given, l=6+w
Perimeter,p =36m
We know that, p= 2(l+w)
p =36=2(6+w+w)
36/2= 6 +2w
18-6=2w
w=6m
Therefore, l=6+w

Answer:
Step-by-step explanation:
sin2x = cosx + l
This can be written as:
2 sinxcosx = cosx + 1
One way would be to draw graphs of sin2x and cosx + 1 and see where they intersect.
Another way is to use y = tan(x/2), then sinx = 2y/(y^2+1) and cos x
= (-y^2 + 1) / (y^2 + 1) to substitute into the given equation and solve for y.

13. A large group of 30 people attended a hockey game. Each person ordered a hotdog or a slice of pizza from the concession stand. Hot dogs cost $2.50 each and a slice of pizza costs $3.25 each. If the total bill for these items was $81.75, how many of each type was purchased?
Answer:
21 hot dogs
9 pizza slices
Step-by-step explanation:
Given information:
Group = 30 peopleCost of a hot dog = $2.50Cost of a slice of pizza = $3.25Total bill = $81.75Define the variables:
Let x = the number of hot dogs purchased.Let y = the number of pizza slices purchased.Create two equations from the given information:
[tex]\textsf{Equation 1}: \quad x + y = 30[/tex]
[tex]\textsf{Equation 2}: \quad 2.5x+3.25y=81.75[/tex]
Rewrite Equation 1 to make x the subject:
[tex]\implies x=30-y[/tex]
Substitute this into Equation 2 and solve for x:
[tex]\implies 2.5(30-y)+3.25y=81.75[/tex]
[tex]\implies 75-2.5y+3.25y=81.75[/tex]
[tex]\implies 75+0.75y=81.75[/tex]
[tex]\implies 0.75y=6.75[/tex]

Substitute the found value of y into the rewritten form of Equation 1 and solve for x:

https://brainly.com/question/27034625
Answer:
Number of hot dogs purchased = 21
Number of pizza slices purchased = 9
Step-by-step explanation:
Let the number of people buying hot dogs be represented by the variable H and the number of people buying pizzas be represented by the variable P
Since H hot dogs were purchased and each hot dog costs $2.50, total amount spent on hot dog purchase = $2.50H
Since P slices of pizza were purchased and each slice of pizza costs $3,25, total amount spent on hot dog purchase = $3,25P
Total amount spent (in $) = 2.50H + 3.25P and we are given that this total amount is $81.75
So we have an equation in two variables
2.50H + 3.25P = 81.75 (1)
We know the number of people is 30 and that should equal the number of hot dogs and pizza slices purchased
So
H + P = 30 (2)
Multiply Equation (2) on both sides by 2.50
==> 2.50(H + P) = 2.50 x 30
2.50H + 2.50P = 75 (3)
Subtract equation (3) from equation (1) to eliminate the H terms
(1) - (3):
2.50H + 3.25P - (2.50H + 2.50P) = 81.75 -75
2.50H + 3.25P - 2.50H - 2.50P = 6.75
Collect like terms and simplify
==> (2.50H -2.50H) + (3.25P - 2.50P) = 6.75
==> 0.75P = 6.75
Divide both sides by 0.75
==> 0.75P/0.75 = 6.75/0.75
==> P = 9
So number of people who bought pizza slices = 9
This is the same as the number of pizza slices that were bought
Substitute for P in Eq (2) H + P = 30
==> H + 9 = 30
Subtract 9 from both sides
==> H + 9 - 9 = 30 - 9
==> H = 21
So number of people who bought hot dogs = 21
This is the same as the number of hot dogs purchased

The value of angle A is 60.
In Euclidean geometry, a parallelogram is a simple quadrilateral having two sets of parallel sides. A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.
We have the angles as:
∠H = 2x + 60
∠T = x + 30
Now, HALT is a parallelogram.
Therefore, angles H and T are supplementary.
So,
∠H + ∠T = 180
2x + 60 + x + 30 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
x = 90 / 3
x = 30
Substituting the value of x in the angles, we get:
∠H = 2x + 60
∠H = 2(30) + 60
∠H = 60 + 60 =120
∠T = x +30
∠T = 30 + 30
∠T = 60
Now, angles T and A are congruent angles.
Therefore, ∠T = ∠A
∠A = 60
