Answer:
4(3)+0.95=X
Step-by-step explanation:
Answer:
A sixth-grade student bought three cans of tennis balls for $4 each.
The sales tax for each can was $0.95.
To Find :
The total amount the student spent.
Solution :
Price of each can including taxes :
p = $( 4 + 0.95 )
p = $4.95
So, price of 3 such cans including tax is :
P = p×3
P = $( 4.95×3 )
P = $14.85
Therefore, total amount spend by the student is $14.85 .

The sum of the speeds of two trains is 724.3 miles per hour. If the speed of the first train is 11.7 mph faster than that of the second train, find the speeds of each.
Answer:
A=368 miles
B= 356.3 miles
Step-by-step explanation:
Given data
Let the two trains be A and B
A+B=724.3----------1
A-B=11.7--------------2
From eqn 1
A= 724.3-B
put this in place of A in eqn 2
724.3-B-B= 11.7
724.3-2B= 11.7
724.3-11.7= 2B
712.6=2B
B= 712.6/2
B= 356.3 miles
Put B=356.3 in eqn 1
A+356.3=724.3----------1
A= 724.3-356.3
A=368 miles

The profits of two different manufacturing plants can be modeled as shown. Where x is the number of units produced at each plant.
Plant 1 : P1 (x) = -0.03x^2 + 25x - 1500
Plant 2 : P2 (x) = -0.02x^2 + 21x - 1700
Find polynomials representing the difference in profits between the companies. Find P1(x) - P2 (x) and P1 (x). Compare the two differences and draw conclusions. Show work and make a equation
P1(x) - P2(x) = -0.01x² + 4x + 200
This shows that P1(x) profit is less than P2(x).
P2(x) - P1x = 0.01x² - 4x - 200
This shows that P2(x) profit is more than P1(x).
What is a polynomial?Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
We have,
Plant 1:
P1 (x) = -0.03x² + 25x - 1500
Plant 2:
P2 (x) = -0.02x² + 21x - 1700
P1(x) - P2(x):
= -0.03x² + 25x - 1500 - (-0.02x² + 21x - 1700)
= -0.03x² + 25x - 1500 + 0.02x² - 21x + 1700
= -0.01x² + 4x + 200
For any x value, we will get a negative value.
This means,
P1(x) profit is less than P2(x).
P2(x) - P1x:
= -0.02x² + 21x - 1700 - (-0.03x² + 25x - 1500)
= -0.02x² + 21x - 1700 + 0.03x² - 25x + 1500
= 0.01x² - 4x - 200
For any x value, we will get a positive value.
This means,
P2(x) profit is more than P1(x).
Thus,
P1(x) - P2(x) shows that P1(x) profit is less than P2(x).
P2(x) - P1x shows that P2(x) profit is more than P1(x).

a) 648 cm
b) 648 m
c) 648 cm
d) 648 m
Answer:
648 cm³
Step-by-step explanation:
For Cuboid
l = 12cm
b = 9cm
h = 6cm
Now, The volume of a cube is
l × b × h
12 × 9 × 6 cm
108 × 6 cm
648 cm³
Thus, The volume of a cuboid 12cm long 9 sm broad and 6 cm high is 648 cm³

The pair of points is on the graph of an inverse variation. Find the missing value.
(2.4, 3) and (5, y)
A. 1
B. 1.44
C. 6.25
D. 0.69
Answer:
Step-by-step explanation:
In verse variation would be 3 = k / 2.4 so k = 7.2
So we have y = 7.2 / 5 = 1.44
Answer is 1.44.
Answer:
Hence, the value of y is:
1.44
Step-by-step explanation:
It is given that:
The pair of points is on the graph of an inverse variation.
(2.4, 3) and (5, y)
We have to find the missing value y in the point.
As we know that in the inverse variation the value of y is the inverse value of x by some k.
i.e. in first point (2.4,3) let 'k' be a number such that:
Hence, the inverse is k=7.2
Now in the second point (5,y) we find the value of y as:
Hence, the value of y is:
1.44
Variation can be direct, inverse, joint or combined.
The missing value of y is (b) 1.44
The points are said to represent inverse variation.
So, we have:
[tex]x_1 \times y_1 = x_2 \times y_2[/tex]
Substitute x and y values in the equation
[tex]2.4 \times 3 = 5\times y_2[/tex]
Multiply 2.4 and 3
[tex]7.2= 5\times y_2[/tex]
Divide both sides by 5
[tex]1.44 = y_2[/tex]
Rewrite as:
[tex]y_2 = 1.44[/tex]
Hence, the missing value of y is (b) 1.44

x = 80°
Step-by-step explanation:
The measure of the angles of the inside of a triangle, when added result in 180°
58° + 42° + x = 180°
x = 180° - 42° - 58°
x = 80°
