A basketball costs $15.00. If the sales tax is 6%, which equation can be used to find the amount of tax?
Answer:
Tax amount = $15.00 x 0.06 =0.9
Total amount of the basketball = $15.00 x 1.06 = $15.90
Answer:
Tax amount = $15.00 x 0.06 =0.9Total amount of the basketball = $15.00 x 1.06 = $15.90

Which is an example of the Associative
Property of Addition?
A. 4 + 2 = 2 + 4
C. 7 + (-7) = 0
B. (2+5) + 7 = 2 + (5+7) D. 8(1) = 8
Answer:
B
Step-by-step explanation:
Answer:
B. (2+5) + 7 = 2 + (5+7)
Step-by-step explanation:
The Associative Property of Addition states that:
(a+b) + c = a + (b+c).
Or, any three or more numbers added together will have the same sum no matter how they are grouped.
Answer choice B is the only choice that exhibits this, and so, B is the answer.

Answer:
(-2, 0, 1, 3)
Step-by-step explanation:
From the given graph, there are four x-intercepts, which are the points the graph crosses the x-axis
Taking the y-axis as the given vertical line, and each demarcation as representing one unit division, we have;
The x coordinates of the x-intercepts are given as follows;
1) Two lines to the left of the origin which represents "-2"
2) Through the origin, which represents "0"
3) One line to the right of the origin which represents "1"
4) Three lines to the right of the origin which represents "3"
The set of values that represents the x-intercepts of the function are;
(-2, 0, 1, and 3)

7.0 x 10^3 + 2.0 x 10^2
Answer:
7200
Step-by-step explanation:
Find the exponents first.
10^3 = 1000
10^2 = 100
So..
7 x 1000 + 2 x 100
Do the multiplication first (BEDMAS - Brackets Exponents Division Multiplication Addition Subtraction).
7000 + 200 = 7200

what will happen to the graph of the line y= 3/4x -7 if you change 3/4 to -3/4?
a) the line will intersect
b) the slope of the line will change from positive to negative
c) (4,-4) will become a point on the line
d) the y-intercept will change from negative to positive
Answer:
B choice
Step-by-step explanation:
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
The value of m is 3/4. That means slope is 3/4. Changing 3/4 to - 3/4 will make the slope become negative. Therefore the answer is B.
Answer: b) the slope of the line will change from positive to negative

Answer:
Here is the summary of true statements:
A) The statement of the function modeled is (0, 3) is TRUE.
D) the equation for the line function is y = 2x+3 is TRUE.
E) the given table represents the linear function is TRUE
Step-by-step explanation:
Given the table
x 1 3 5 7
y 5 9 13 17
E)
It is clear that there is a CONSTANT CHANGE in the x and y values of the graph.
THE CONSTANT CHANGE IN X VALUES
i.e. 3-1=2, 5-3=2, 7-5=2
THE CONSTANT CHANGE IN Y VALUES
i.e. 9-5 = 4, 13 - 9 = 4, 17 - 13 = 4
Thus, the given table represents the linear function is TRUE
B)
It is clear that the value of y increase as the value of x increases.
Thus, the statement ''the value of y decreases as the value of x increases'' is FALSE!
D)
We know that the slop-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept.
Determining the equation
Taking two points
(1, 5)
(3, 9)
Finding the slope between (1, 5) and (3, 9)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [9 - 5] / [3 - 1]
= 4 / 2
= 2
Thus, the slope of the line = m = 2
now substituting m = 2 and the point (1, 5) to determine the y-intercept
y = mx+b
5 = 2(1) + b
b = 5-2
b = 3
Thus, the value of y-intercept b = 3
substituting b = 3 and m = 2 in the slope-intercept form
y = mx+b
y = 2x+3
Therefore, the equation for the line function is y = 2x+3 is TRUE
A)
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
We already know that the y-intercept b = 3
It means the y-intercept modeled is (0, 3)
Therefore, the statement of the function modeled is (0, 3) is TRUE.
C)
We have already got the equation
y = 2x+3
substituting x = 8
y = 2(8)+3
y = 10+3
y = 13
so at x = 8, the value of y = 13
Therefore, the statement that the ''On a graph of the function when x = 8, the value of y will be 2'' is FALSE!
Conclusion:
Here is the summary of true statements:
A) The statement of the function modeled is (0, 3) is TRUE.
D) the equation for the line function is y = 2x+3 is TRUE.
E) the given table represents the linear function is TRUE

Answer:
A scale factor of 4in to 5in should be used
Step-by-step explanation:
Given
[tex]Original\ Measurement = 4.5\ in[/tex]
[tex]Scale\ Measurement = 3.6\ in[/tex]
Required
Determine the scale to use
The scale to use can be represented as:
[tex]Scale = Scale\ Measurement : Original\ Measurement[/tex]
This gives:
[tex]Scale = 3.6\ in : 4.5\ in[/tex]
Divide by 0.9
[tex]Scale = \frac{3.6}{0.9}\ in : \frac{4.5}{0..9}\ in[/tex]
[tex]Scale = \frac{3.6}{0.9} : \frac{4.5}{0.9}[/tex]
[tex]Scale = 4 : 5[/tex]
What is the equation of the line that passes through the point (-3,4) and has a slope of zero?
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1, thus
y = x + c ← is the partial equation
To find c substitute (- 3, 4) into the partial equation
4 = - 3 + c ⇒ c = 4 + 3 = 7
y = x + 7 ← equation of line
Hope this helps.

and
g(x) = 5x + 7
Find
f(g(x)) = [ ? ]x2 +[ ]x + [ ]
9514 1404 393
Answer:
f(g(x)) = 50x² +140x +93
Step-by-step explanation:
Put the function argument in place of x and simplify.
f(g(x)) = f(5x+7) = 2(5x+7)² -5
= 2(25x² +70x +49) -5
f(g(x)) = 50x² +140x +93

Noa is making a circular party cake for her sister Léa. He only has the icing left to put on his cake which measures 22cm in radius and which has a height of 11cm. He ran to the store with his remaining $ 5.33 and chose two types of ice cream. The most beautiful but the most expensive will cost him $ 0.20 / 100cm2. Can he buy it or must he take the one that is less expensive?

The rational number lies between −67/7 and−78/8
Pls explain and pls don't write bad answer pls
9514 1404 393
Answer:
-135/14
Step-by-step explanation:
There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...
-67/7 = -9 4/7 = -9.571428... (repeating)
-78/8 = -9 3/4 = -9.75
So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.
If you like, you can convert these numbers to ones with a common denominator (56).
-67/7 = -536/56
-78/8 = -546/56
These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.
A car is traveling at a rate of 35 meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 3 hours? Do not round your answers.
Answer:
126 km/h
378 km
Step-by-step explanation:
To convert m/s into km/h, we multiply it by 3.6.
35 m/s x 3.6 = 126 km/h.
Distance travelled in 3 hours = 126 x 3 km = 378 km.
URGENT‼️‼️‼️ solve the triangle using law of sines and cosines.
Answer:
[tex]m\angle C=20^{\circ}\\m\angle B = 127^{\circ}\\b=37\\[/tex]
Step-by-step explanation:
The Law of Sines for any triangle is:
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex]
Let's solve for [tex]m\angle C[/tex] first:
[tex]\frac{\sin33^{\circ}}{25}=\frac{\sin (m\angle C)}{16},\\\sin (m\angle C)=\frac{16\cdot \sin33^{\circ}}{25}, \\m\angle C= \sin^{-1}(\frac{16\cdot \sin33^{\circ}}{25})\approx \fbox{$20^{\circ}$}[/tex]
Since the sum of the interior angles in a triangle is always [tex]180^{\circ}[/tex], the measure of angle B is [tex]m\angle B=180-33-20=\fbox{$127^{\circ}$}[/tex].
Now we can use to solve for side length [tex]b[/tex]:
[tex]\frac{\sin33^{\circ}}{25}=\frac{\sin 127^{\circ}}{b},\\b=\frac{25\cdot \sin127^{\circ}}{\sin33^{\circ}}\approx \fbox{37}[/tex].
