Mario walked 7422 steps one day then he walks 5570 stops the next day. which calculation can be used to find the total number of steps Mario walked two days
Answer:
A caucluation he can use is adding, just add 7422 and 5570 and you should get your answer.
Step-by-step explanation:
Mario walked total 12992 steps.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mario walked 7422 steps one day
and, he walks 5570 stops the next day.
So, the total number of steps
= 7422 + 5570
= 12992 steps
Hence, Mario walked total 12992 steps.

The solution of the given inequality v +8 <3 or 8v <-40 is v < -5.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal.
Given the inequality,
v +8 < 3
Adding -8 on both sides
v + 8 - 8 < 3 - 8
v < -5
Or,
8v <-40
Divide 8 on both side
v < -5
Hence "The solution of the given inequality v +8 <3 or 8v <-40 is v < -5".

The function has no intercepts.
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The x-intercept is the point on the x-axis when y= 0.
The y-intercept is the point on the y-axis when x= 0.
We see that,
There is no point on the x-axis or y-axis that the graph is touching.
So,
We can say that,
There are no x-intercepts and y-intercepts.
Thus,
The function has no intercepts.

(10,y) and (3,4) m= -2/7
Answer:
y = 2Step-by-step explanation:
Using slope formula and solving for y
m = (y2 - y1)/(x2 - x1)
-2/7 = (4 - y)/(3 - 10)-2/7 = (4 - y)/-72 = 4 - yy = 4 - 2y = 2Answer:
y = 2
Step-by-step explanation:
Using slope formula and solving for y
m = (y2 - y1)/(x2 - x1)
-2/7 = (4 - y)/(3 - 10)
-2/7 = (4 - y)/-7
2 = 4 - y
y = 4 - 2

1. Given x=5, plug x into y=10x-2.
a. 38
b. 12.
C. 13
d. 48
Answer:
D. 48
Step-by-step explanation:
y=10x-2 is our equation
If x is 5, then multiply 10 by 5. You get 50.
Subtract 2 from that. You get 48.
Answer:
D, 48
Step-by-step explanation:
Given x=5, plug x into y=10x-2
First you should plug the given x into the x in the equation. And put () around it.
y=10(5)-2
Now you multiply 10 by 5 and you get 50.
y=50-2
Now the last step is to subtract 2 from 50 which you will end up getting y=48. So the answer is y=48 which is letter D.

Step-by-step explanation:
Answer:
an inverse function is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g = x.
A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation 1.5s+3.5c=21 represents the relationship between sheets of stickers, s, packs of cardstocks, c, and the dollar amount a kindergarten teacher spent on these supplies.
1. Explain how we can tell that this graph represents the give equation.
2. What do the vertical and horizontal intercepts, (0,6) and (14,0), mean in this situation?
Answer:
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1). [tex]c=-\frac{3}{7}x+6[/tex]
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.

Please solve this question.(Quadratic equation)
Answer: 28
Step-by-step explanation:
Let x represent the digit in the tens place and y represent the digit in the ones place. xy → 10x + y
The square of the sum of the digits is 100.
EQ1: (x + y)² = 100 → x + y = 10
2 is subtracted from 3 times the number is the digits reversed.
EQ2: 3(10x + y) - 2 = 10y + x → 30x + 3y - 2 = 10y + x → 29x - 7y = 2
Solve the system of equations using the Elimination method:
EQ1: x + y = 10 → 7(x + y = 10) → 7x + 7y = 70
EQ2: 29x - 7y = 2 → 1(29x - 7y = 2 → 29x - 7y = 2
36x = 72
÷36 ÷36
x = 2
Substitute x = 2 into either of the equations to solve for y.:
EQ1: x + y = 10
2 + y = 10
y = 8
The digit is: 28
EDGE 2020 The average monthly high temperatures for Phoenix, Arizona from the years 1981-2010 are shown in the table below, with the value 1 representing the month of January, and the value of 12 representing the month of December. Complete the following steps to model the curve using the sine function.
a. Make a scatterplot of the data.
b. What is the minimum temperature in the data set?
c. What is the maximum temperature in the data set?
d. What is the vertical shift, k, for the data set?
e. What is the amplitude, a, for the data set?
f. What is the period and frequency factor for the data set?
g. What is the phase shift for the data set?
h. Write an equation using the sine function that models this data set.
i. When would you expect the temperature in Phoenix to be 82°?
Answer:
a. Please find attached the required scatter plot
b. The minimum temperature in the data set is 67°F
c. The maximum temperature in the data set is 106°F
d. The vertical shift for the data set is 67°F
e. The amplitude 19.5 °F
f. The period is 12 months, the frequency = 1/12 months
h. The sine function equation that models the data set is 19.5·sin(π·t/6 - π/2) + 86.5
i. After the second and before the third month or after the ninth and before the 10th month
Step-by-step explanation:
The equation for the sinusoidal variation of temperature with time can be presented as follows;
y = A·sin(Bt + C) + D
Where;
A = The amplitude = (The Maximum value - The minimum value)/2
The amplitude = (106 - 67)/2 = 19.5°F
B = 2·π/(The period) = 2·π/12 = π/6
t = The time in months
C = The phase shift = -π/2
D = The midline = (The Maximum value + The minimum value)/2 = (106 + 67)/2 = 86.5 °F
The equation that models the data = 19.5·sin(π·t/6 - π/2) + 86.5
When the temperature is 82°, we have;
82 = 19.5·sin(π·t/6 - π/2) + 86.5
82 - 86.5 = 19.5·sin(π·t/6 - π/2)
-4.5°F = 19.5·sin(π·t/6 - π/2)
sin⁻¹(-4.5/12) = π·t/6 - π/2
-0.3844 = π·t/6 - π/2
-0.2329 = π·t/6 - π/2
t = 2.55 or 12 - 2.55 = 9.44
Which is either after the second and before the third month or after the ninth and before the 10th month.
In this exercise we have to use the function knowledge to calculate the temperature that is requested in each alternative, so we have to:
a. The answer is in the scatter plot
b. The minimum is 67°F
c. The maximum is 106°F
d. The vertical shift is 67°F
e. The amplitude 19.5 °F
f. The frequency is 1/12 months and the period is 12.
h. The sine function equation that models the data set is [tex]19.5sin(\pi t/6 - \pi /2) + 86.5[/tex]
i. After the second and before the third month or after the ninth and before the 10th month
The equation for the sinusoidal variation of temperature with time can be presented as follows;
[tex]y = Asin(Bt + C) + D[/tex]
Where;
A = [tex](106 - 67)/2 = 19.5\°F[/tex]B = [tex]2\pi /(T) = 2\pi/12 = \pi/6[/tex]t = 12 C = [tex]\pi/2[/tex]D = [tex](106 + 67)/2 = 86.5 \°F[/tex]The equation that models the data is given by:
[tex]19.5sin(\pi t/6 - \pi/2) + 86.5[/tex]
When the temperature is 82°, we have;
[tex]82 = 19.5sin(\pi t/6 - \pi/2) + 86.5\\82 - 86.5 = 19.5sin(\pi t/6 - \pi/2)\\-4.5\°F = 19.5sin(\pi t/6 - \pi/2)\\sin^{-1}(-4.5/12) = \pi t/6 - \pi /2\\-0.3844 = \pi t/6 - \pi /2 \\-0.2329 = \pi t/6 - \pi /2\\t = 2.55 \ or \ 9.44[/tex]
Which is either after the second and before the third month or after the ninth and before the 10th month.
