ohn drove from Miami to Atlanta, and the trip took him a total of 10 hours.
For 6 hours John’s average speed was 73 mph. His average speed on the remainder of the
trip was 67 mph. What was his average speed on the entire trip?
a) 70.8 mph
b) 70.6 mph
c) 69.4 mph
d) 68.2 mph
Answer:
b) 70.6
Step-by-step explanation:
To calculate average you need to add up all the numbers and divide by the quantity of numbers. They are calculating with mph, with ten hours, so there will be ten numbers. First you do 73 x 6 (6 because of 6 hours of 73 mph) which is 438. Then you do 67 x 4 which is 268. you add it up, then find a total of 706. Then you divide it by ten to find the answer 70.6

Step-by-step explanation:
[tex]9x^{2}y^{-2}[/tex]
If We replace x by -3 and y by 2 we get :
[tex]9\left( -3\right)^{2} \left( 2\right)^{-2}[/tex]
Or we have :
[tex]\left( -3\right)^{2} =9\ \text{and} \ \left( 2\right)^{-2} =\frac{1}{2^{2}} =\frac{1}{4}[/tex]
then
[tex]9\left( -3\right)^{2} \left( 2\right)^{-2}=9\times9\times\frac{1}{4} = \frac{81}{4}[/tex]
on the other hand :
[tex]\frac{81}{4} =\frac{80+1}{4} =\frac{80}{4} +\frac{1}{4} =20+\frac{1}{4}=20\frac{1}{4}[/tex]

What are the solutions to the equation 3(x – 4)(x + 5) = 0?
O x = -4 or x = 5
O x = 3, x = 4, or x = -5
O x = 3, x=-4, or x = 5
O x = 4 or x = -5
The solutions of the given equation are x = 4 or x = -5.
What is solution of an equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations.
Given is an equation, 3(x – 4)(x + 5) = 0 we need to find the solution of the equation,
So, we can see that the equation is a quadratic equation, so it will have two solutions,
The equation is already in factored form,
So,
3(x – 4)(x + 5) = 0
Solution,
x-4 = 0
x = 4
x+5 = 0
x = -5
Hence, the solutions of the given equation are x = 4 or x = -5.

The cost for each person appears to be the same.
Predicted number in group for a cost of $40:
Answer:
The cost for each person is not always the same.10 peopleStep-by-step explanation:
Number : 2 Cost : $10
Per person = 10/2 = $5Number : 3 Cost : $15
Per person = 15/3 = $5Number : 7 Cost : $28
Per person = 28/7 = $4⇒ The cost is not always the same per person.
⇒ Predicted number in a group for cost of $40 :
⇒ Since 7 costs $28 and if we use 8, it will be $5 per head but the price difference will be too large
⇒ 10 people is more reasonable at a rate of $4 per person

Sylvia applies two transformations to WXYZ shown below on the coordinate grid. She applies a reflection across the y-axis and then a rotation of 180° counterclockwise about the origin.
What are the coordinates of the final vertices of the two transformations?
coordinates: ________________________
The coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)
How to determine the final vertices?The coordinates of the polygon WXYZ are:
W = (-4,-1)
X = (-2,-1)
Y = (-2,-4)
Z = (-3,-2)
When reflected across the y-axis, the rule of transformation is:
(x,y) -> (-x,y)
So, we have:
W' = (4,-1)
X' = (2,-1)
Y' = (2,-4)
Z' = (3,-2)
When rotated by 180 degrees, the rule of transformation is:
(x,y) -> (-x,-y)
So, we have:
W" = (-4,1)
X" = (-2,1)
Y" = (-2,4)
Z" = (-3,2)
Hence, the coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)

The volume of a spherical balloon with radius 2.8 cm is about 92 cm^3. Estimate the volume of a similar balloon with radius 8.4 cm.
Step-by-step explanation:
it means the shape of the balloon is close to a sphere.
the volume of a sphere is
4×pi×r³
so, it bases on r³.
that means any scaling factor f between 2 similar balloons for the radius has to be multiplied in 3 times (once for every "r").
in our case we know
8.4 = 2.8 × f
f = 8.4 / 2.8 = 3
so,
large volume = small volume × f×f×f =
= small volume × f³ = 92×3³ = 92×27 =
= 2,484 cm³

Since the resulting function has a leading degree of 1, hence the set or ordered pairs (1,6), (2,9), (3,12), (4,15) satisfies a linear function
How to find a linear function?The standard equation of a linear function is y = mx + b
where:
m is the slopee
b is the y-intercept
Using the coordinate point (1, 6) and (2, 9)
Find the slope

Answer:
If one counts the blocks on the graph from the school to the stadium and back, there are three blocks one way and three blocks going back.
Altogether 6 blocks.
If Catelyn lives halfway between the park and the school, the amount of blocks is 5.
She lives halfway between. Hence, what is 5 divided by 2?

Make a very crude diagram of what these points look like. You will find that
(-8,6) is above (-8,3) (-3,6) is above (-3,3)That gives you a hint about how to find the Length and width.
Givens
From (-8,-3) and (-3, 3) L = -8 - -3 = - 5
From (-8,6) and (-8,3) w = 6 - 3 = 3
Solution
The length cannot be minus 5. The way to get around that is to call it and absolute value of (-5) which is 5
So the area = L*W
area = 5 *3
area = 15

Answer:
3. -1/3 ± 2i√5 / 3
Step-by-step explanation:
3x^2 + 2x = -7
Divide through by 3:
x^2 + 2/3 x = -7/3
Completing the square:
x^2 + 2/3 x + (1/3)^2 = -7/3 + (1/3)^2
(x + 1/3)^2 = -7/3 + 1/9
(x + 1/3)^2 = -20/9
x + 1/3 = ±√(-20) / 3
x + 1/3 = ± 2√-5/3
x = -1/3 ± 2i√5 / 3
