A Toyota Prius is 178.7 inches long. How many would you need to circle Mars’ equator, which is 13,233 mile long?
Answer:
4,691,902
Step-by-step explanation:
There are 5280 ft per mile, and 12 inches per foot. There are 178.7 inches per Prius. The number needed is ...
(13233 mi)(5280 ft/mi)(12 in/ft)/(178.7 in/Prius)
= (13233×5280×12/178.7) Prius
= 4,691,901.95 Prius
With a little squeezing, you could gain the extra 7.4 inches necessary to round this number to the next higher integer value:
4,691,902 Prius cars would be needed to circle Mars at the equator

Find an equation of the line parallel to y=x+3 and that passes through the point (1 -5)
Answer:
y=x-6
Step-by-step explanation:
Y=x+3 according to this equation, the gradient is 1 comparing to y=mx+c. so m is the gradient. so from the equation, the coefficient of x is 1. since the line is parallel so it means the new equation has the same gradient m.
y=x+c but it passes through 1,-5...when x= 1, y=-5 from here , we Can find the new intercept c. -5=1+c. so c=-5-1=-6
the new equation y=x-6

A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
Answer:
Building to the left is taller.
Step-by-step explanation:
Kindly refer to the attached diagram for the given dimensions.
[tex]\triangle ABR, \triangle PQR[/tex]
AB and PQ be the two buildings.
The car be parked at point R.
[tex]\angle ARB = 50^\circ\ and \\\angle PRQ = 40^\circ[/tex]
Distance of R from building bases:
BR = 49 m
QR = 56 m
Let us use tangent in [tex]\triangle PQR:[/tex]
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tan40 = \dfrac{h_1}{56}\\\Rightarrow h_1 = 56 \times 0.839 \\\Rightarrow h_1 \approx 47\ m[/tex]
Let us use tangent in [tex]\triangle PQR:[/tex]
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tan50 = \dfrac{h_2}{49}\\\Rightarrow h_2 = 49 \times 1.19 \\\Rightarrow h_2 \approx 58.4\ m[/tex]
So, building to the left is taller.

At Statebert University, 70% of the students are female. If there are 210 male students
at Statebert U., how many female students are there?
Answer:
490 female students
Step-by-step explanation:
If 70% of students are female, 30% are male.
If 30% of students = 210 students, we can divide both sides of the equation by 3.
30/3 = 10
210/3 = 70
10% of students = 70 students
To get 70% of students, multiply both sides by 7.
10*7 = 70
70 * 7 = 490
70% of students = 490 students

OPTION 2
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular x value. The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
--------------------------------------------------------------------------
HOW TO: GIVEN A GRAPH, USE THE VERTICAL LINE TEST TO DETERMINE IF THE GRAPH REPRESENTS A FUNCTION.
1.Inspect the graph to see if any vertical line drawn would intersect the curve more than once.
2.If there is any such line, the graph does not represent a function.
3.If no vertical line can intersect the curve more than once, the graph does represent a function.
(The 2nd pic represents a graph that has a function)

[tex]7.25 \leqslant x[/tex]
Step-by-step explanation:
you do 1.5×8 to see how much shipping cost
you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25
so he needs to spend $7.25 or more on each friend. (im pretty sure)
The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.
Let the cost of each gift = c
urgio is buying gifts for 8 friends = 8 gifts
Hence, the Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

If Marcus drives no faster than 65 miles per hour, what is the domain that includes all possible average speeds using interval notation?
A [0.65)
B. [65,00)
C. (0.65)
D. (65.00)
Answer:
{0, 65]
Step-by-step explanation:
A function shows the relationship between two variables (an independent and dependent variable). The independent variable is not dependent on other variables, it is considered as the input while the dependent variable is dependent on other variables and considered as output.
The speed of Marcus must not be faster than 65 mph, hence speed ≤ 65 mph. This means that Marcus can drive with speed ranging from 0 mph to 65 mph, hence 0 ≤ speed ≤ 65 mph. This is represented using the interval notation:

The water level in the beaker was 10 mL before the small toy was placed into it. After the toy was submerged in the water, the level was 23 mL. The toy has as much volume as how many mL of water?
Answer:
volume of toy = volume of water after placing toy in it - volume of water before placing toy in it
volume of toy = 23mL - 10mL
volume of toy = 13mL
The increase in the volume of water when the toy is submerged in it is equal to the volume of the toy.
SO VOLUME OF WATER IS 13mL
You plan to rent a car from XYZ Car Rental Company for a flat rate of $35 a
day. If you plan to use the car for 3 days or fewer, you must also pay a $10
insurance fee per day. If you plan to use the car for more than 3 days, there is
a $5 insurance fee per day. Write a piecewise-defined function that models this
function.
Thanks for any help!
Answer:
The piece-wise function is;
[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]
Step-by-step explanation:
The flat rate for renting the car = $35 per day
The amount charged as insurance fee per day for renting the car for 3 days or less = $10
The insurance fee charged per day when the car is rented for more than 3 days = $5
Let the number of days = x
Therefore, we have;
For x ≤ 3, f(x) = 35 × x + 10 × x = x × (35+10) = 45·x
For x > 3, f(x) = 35 × x + 5 × x = x × (35+5) = 40·x
Therefore;
The charge rate for renting the car for less than or equal to 3 days = 45·x
The charge rate for renting the car for more than 3 days = 40·x
The piece-wise function can be presented as follows;
[tex]f\left (x \right ) = \begin{cases} \$ 45 \times x & \text{ if } x \leq 3 \ days \\ \$40 \times x & \text{ if } x > 3 \ days\end{cases}[/tex]
