what is 0.728416 rounded to the nearest tenth
Answer:
0.7
Step-by-step explanation:
In order to determine if the tenth place is rounded up one number or stay the same, you have to look at the hundredths place. In this scenario it's the 2.
0.728416
If the hundredths place is 5 or greater, you round up in the tenth place. If the hundredths place is 4 or less you keep the same number in the tenth place.

The students in Ms. Baca's art class were mixing yellow and blue paint. She told them that two mixtures will be the same shade if the blue and yellow paint are in the same ratio. How many different shades of paint did the students make?
Answer:
Two shades will be prepared.
Step-by-step explanation:
Ms Baca told the students that when two colors yellow and blue are mixed in the same ratio same shade is prepares.
From the table attached,
If A is a mixture of 1 part yellow and 2 parts of blue color,
Ratio of the colors = 1 : 2
If B is a mixture of 2 parts yellow and 3 parts of blue color,
Ratio of the colors = 2 : 3
If C is the mixture of 3 parts yellow and 6 parts of blue color,
Ratio of the colors = 3 : 6 = 1 : 2
If D is a mixture of 4 parts yellow and 6 parts of blue color,
Ratio of the colors = 4 : 6 = 2 : 3
If E is a mixture of 6 parts yellow and 9 parts of blue color,
Ratio of the colors = 6 : 9 = 2 : 3
Therefore, mixtures A, C will create the same shade while mixtures B, D, E will be of same shade but different from A and C.
Two shades of the paints will be made by the students.

Step-by-step explanation:
If the circumference of a circle is increased by 40%,
then the area of the circle is increased by
A. 18%. B. 20%. C. 40%. D. 96%.
Answer:
96%
Step-by-step explanation:
c=100=22/7D
D=7/22×100
get the radius and find the area
R=D/2
A=pi×r^2
repeat that assuming
C=140
get the area
find the %age
A2_A1=Area difference
A(diff)/A1×100=96.01%
[tex]r_{2}[/tex]Answer:
D) 96%
Step-by-step explanation:
let the circumference of circle be C = 2π[tex]r_{1}[/tex] and [tex]r_{1}[/tex] = [tex]d_{1}[/tex]/2
Initial radius (radius before increment) = [tex]r_{1}[/tex]
initial diameter (diameter before increment) = [tex]d_{1}[/tex]
Increasing the circumference of a circle other factors are constant except the radius which can be used to find the diameter hence increasing the circumference of a circle is equivalent to increasing the diameter
area of the circle before increment [tex]A_{1}[/tex] = π[tex]r_{1}[/tex]²
[tex]A_{1}[/tex] = π × ([tex]d_{1}[/tex]/2)²
[tex]A_{1}[/tex] = π[tex]d_{1}[/tex]²/4
Increment of circumference results to increment of only the diameter
diameter after increment by 40%, [tex]d_{2}[/tex] = 1.4[tex]d_{1}[/tex]
1.4 represents increment by 40%
radius after increment [tex]r_{2}[/tex] = [tex]d_{2}[/tex]/2 = 1.4[tex]d_{1}[/tex]/2 = 0.7[tex]d_{1}[/tex]
area after increment, [tex]A_{2}[/tex] = π[tex]r^{2} _{2}[/tex]
[tex]A_{2}[/tex] = π(0.7[tex]d_{1}[/tex])²
[tex]A_{2}[/tex] = π × 0.49[tex]d_{1}[/tex]²
Change in area = [tex]A_{2}[/tex] - [tex]A_{1}[/tex]
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π × 0.49[tex]d_{1}[/tex]² - π [tex]d_{1}[/tex]²/4
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π [tex]d_{1}[/tex]²(0.49 - ¼)
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = π [tex]d_{1}[/tex]²(0.49 - 0.25)
[tex]A_{2}[/tex] - [tex]A_{1}[/tex] = 0.24 π[tex]d_{1}[/tex]²
Percentage increment = ([tex]A_{2}[/tex] - [tex]A_{1}[/tex]/ [tex]A_{1}[/tex]) × 100
= ((0.24 π[tex]d_{1}[/tex]²)/(π[tex]d_{1}[/tex]²/4)) × 100
= (0.24 × 4 ) × 100
= 0.96 × 100
= 96 %

A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game. The least-squares regression line is y = 5. 0 + 1. 2x, where y is the predicted number of points scored and x is the number of shots taken. In one game, a team takes 50 shots and the residual is –10. How many points were scored by this team in this game?
45
55
65
75
Answer:
65
Step-by-step explanation:
y= 5.0 + 1.2x
when x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
The value of y is 65 when x = 50, or the number of points the team was scored was 65.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A sports analyst determines that the number of points scored in a basketball game is related to the number of shots taken during the game.
y= 5.0 + 1.2x
Plug x = 50
y = 5.0 + 1.2 x 50
= 5.0 + 60
= 65
Thus, the value of y is 65 when x = 50, or the number of points the team was scored was 65.

Central angle BAC of circle A measures 20" radians. Arc BC has a length of 63.487 centimeters. What is the radius of the circle?
The radius of circle A is ✓ centimeters.
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] ( r is the radius )
given arc = 63.48π , then
2πr × [tex]\frac{\frac{23}{20}\pi }{2\pi }[/tex] = 63.48π ( cancel 2π on numerator/ denominator )
r × [tex]\frac{23}{20}[/tex] π = 63.48π ( divide both sides by π )
[tex]\frac{23r}{20}[/tex] = 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
Answer: 55.2

Keeping car tires inflated is essential to safe driving. For one type of car tire, the tire pressure in pounds per square inch (psi) is assumed to be approximately Normal, with a mean of 35 psi and a standard deviation of 2 psi. What percentage of tires are inflated to a pressure above 36 psi?
Answer:
30.854%
Step-by-step explanation:
First, we find the z-score corresponding to the value given
z-score = (x - mean)/SD
Z-score = (36-35)/2 = 1/2 = 0.5
we find the Probability of (x > 0.5)
we use the standard normal distribution table for this
P( x > 0.5) = 0.30854
This has a percentage 30.854%
Answer:
30.854%

Which is a function and not a function
Answer:
Function: A, C, F, H,I
NOT: B,D,E,G
Step-by-step explanation:
To be a function every x is only allowed to pair up with one y. If there's no repeated x's, then its a function. If x repeats, it has to have the same y as the first time it showed up. If a vertical line (up and down) touches a graph in more than one place, its NOT a function. Any y can partner up with however many x's it wants to, doesn't matter, its still a function. But to be a function ONLY ONE y for each x. Life's not fair.

On a piece of paper, use a protractor to construct a triangle with angle measures of 60° and 80°. I Which statements about this triangle are true? Select all correct answers.
Answer:
Option A
Option C
Option D
Step-by-step explanation:
Triangle attached in image~
A) It is an acute triangle (Yes)
Before we put reasonings why this is true, let's find the missing angle in the triangle.
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°This triangle is an acute triangle because all angles in the triangle are acute, as 80°, 60°, 40° are acute angles.
B) Two sides have the same length (No)
Two sides can only be the same if two angles are equivalent. Since all angles are different, two sides cannot have the same length.
C) All sides have different lengths (Yes)
Since all angles are unalike, the triangle has different side lengths.
D) The third angle measures 40° (Yes)
⇒ 60 + 80 + x = 180°⇒ 140 + x = 180°⇒ x = 180 - 140⇒ x = 40°Answer:

No receives a $5 discount each month on his cell phone bill because he signed up for autoplay from his bank account over the last eight months nor has pay a total of $284 for his cell phone bill what would Noah be charged for his cell phone bill each month if he stopped using autoplay?
Answer:
$36Step-by-step explanation:
Normally Noah is expected to pay an amount without a discount.
let this amount be x
so the amount paid monthly after the discount is removed is (x-5)
Noah paid this amount for 8 months
(x-5)*8=248
solving for x we will get the amount that Noah is expected to be charged when he stopped using the autoplay
(x-5)*8=248
8x-40=248
8x=248+40
8x=288
divide both sides by 8 we have
x=288/8
x=$36

Use the angle relationship in the figure below to solve for x. Assume that line A and line B are parallel, line C is a transversal and the given angles are given in
degrees
AC
4x+29
12x+55
B
Answer:
x = 6
Step-by-step explanation:
The 2 angles given are same- side interior angles and are supplementary, thus
4x + 29 + 12x + 55 = 180, that is
16x + 84 = 180 ( subtract 84 from both sides )
16x = 96 ( divide both sides by 16 )
x = 6
