Answer:
65.1 km/hr
Step-by-step explanation:
The car travelled 217km in 3 hours and 20 minutes. We can divide the km by the time to obtain a speed that is km per a time value. If we would like it expressed as km/hour, we will need to convert the 20 minutes into hours.
20 minutes is (20 minutes)*(1 hour/60 minutes) = (1/3) hour
The total time to travel 217km is 3 and 1/3, or (10/3) hours.
The speed is (217 km/((10/3) hours)
Speed = 65.1 km/hr

does y+x=1 show direct variation
Answer:
No
Step-by-step explanation:
Equations with direct variation follow the form y= kx, where k = constant of proportionality.
To find out if y + x = 1, we need to isolate y by itself.
Step 1: Subtract x from both sides.
[tex]y+x-x=1-x[/tex] [tex]y=-x+1[/tex]As you can see, y + x = 1 does not show direct variation.

Suppose you bought something
that was priced at $6.95, and the
total bill was $7.61.
What is the sales tax rate in this
city?
Subtract to find the amount of tax paid then divide the amount of tax paid by the price of the item bought.
7.61 - 6.95 = 0.66 (amount of tax paid)
0.66/6.95 = 0.0949 x 100 = 9.49 %
Answer: 9.49 % (round off as needed)
what is 2/3 as many as 18
Answer:
12
Step-by-step explanation:
Multiply 2/3 and 18. Since it a whole number, convert it to a fraction by putting it over a denominator of 1. When multiplying fractions, calculate numerator times numerator, then denominator times denominator. Multiply 2/3 x 18/1 to get 36/3.
Simplify the resulting fraction as needed by dividing it by the common denominator. The common denominator of 36 and 3 is 3. Diving 36 and 3 by 3 gives you a fraction of 12/1, which is the same as 12. Thus, two-thirds of 18 is 12.
[tex]\frac{2}{3}*\frac{18}{1}[/tex]
[tex]=\frac{36}{3}[/tex]
[tex]=\frac{12}{1}[/tex]
[tex]=12[/tex]

Lucy graphed the equations x + 9 y = 5 and 4 x + 15 y = negative 1 and saw that they intersected at the point (–4, 1) as shown.
On a coordinate plane, 2 lines intersect at (negative 4, 1).
What can Lucy conclude?
(–4, 1) is a solution to the system of linear equations.
(–1, 4) is a solution to the system of linear equations.
(1, –4) is a solution to the system of linear equations.
(4, –1) is a solution to the system of linear equations.
Answer: A
Step-by-step explanation:
You can solve a system of equations by graphing, elimination, substitution, or using a combination. The graph of a linear equation is a line. The point(s) where one line intersects another is the solution to the system. Therefore, since Lucy found that the lines intersected at the point (-4, 1), it is the solution to the system of linear equations

Find the odd number less than 100, that is divisible by 7, and when divided by 10 has a remainder of 3.
Answer:
63
Step-by-step explanation:
Multiples of 7 that are less than 100:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98
If when a number is divided by 10 it has a remainder of 3, look for the mulitple of 7 with "3" as its units. Therefore, the number is 63.
Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate Pi.
Given:
Radius of circle = 3 ft.Height of triangle = 4 ft.1. Finding the area of the semi-circle:Since the area of the semi-circle is the area of half the circle, the formula of finding the area of the circle will be divided by 2 to find the area of the semi-circle.
This means that:
Area of semi-circle = Area of circle/2 = πr²/2Now, let's substitute the radius into the formula to find the area.
Substituting the radius into the equation:
Area of semi-circle = πr²/2 => Area of semi-circle = (π)(3²)/2Simplifying the RHS:
=> Area of semi-circle = (π)(3²)/2 => Area of semi-circle = (π)(9)/2Substituting π as 3.14:
=> Area of semi-circle = (π)(9)/2 => Area of semi-circle = (3.14)(9)/2Simplifying the RHS:
=> Area of semi-circle = (3.14)(9)/2 => Area of semi-circle = (1.57)(9)=> Area of semi-circle = 14.132. Finding the area of the triangle:Before we find the area of the triangle, we need to know the base, which is the diameter of the semi-circle.
Diameter = 2(Radius)=> Diameter = 2(3)=> Diameter = 6 feetNow, let's find the area of the triangle.
Area of triangle = 1/2 x 6 x 4=> Area of triangle = 3 x 4=> Area of triangle = 12 ft²3. Finding the area of the figure:The area of the figure is basically the sum of the semi-circle and the triangle.
=> Area of figure = Area of triangle + Area of semi-circle=> Area of figure = 12 + 14.13=> Area of figure = 26.13 ft²Thus, the area of the figure is 26.13 ft².
