To convert a temperature measured in degrees Fahrenheit to degrees Celsius, there is a formula
C=5/9(F-32)
where C represents the temperature in degrees Celsius and F represents the temperature in degrees Fahrenheit.
If a temperature is 113`F, what is that temperature measured in Celsius?
Answer:
113`F= 46.11° Celsius
Step-by-step explanation:
(Celsius°C × 9/5) + 32 = Fahrenheit
(Celsius°C × 9/5) + 32 = 113
(Celsius°C × 9/5) = 113 - 32
(Celsius°C × 9/5) = 83
Celsius = 5(83)/9
Celsius = 46.11° Celsius
[tex]\\ \tt\hookrightarrow C=5/9(F-32)[/tex]
[tex]\\ \tt\hookrightarrow C=5/9(113-32)[/tex]
[tex]\\ \tt\hookrightarrow C=5/9(81)[/tex]
[tex]\\ \tt\hookrightarrow C=5(9)[/tex]
[tex]\\ \tt\hookrightarrow C=45°C[/tex]
A video game costs $16.40 before tax. What is the total cost after the 5% sales tax?
Answer:
$17.22
Step-by-step explanation:
→ Find the multiplier
( 100 + 5 ) ÷ 100 = 1.05
→ Multiply answer by cost
16.40 × 1.05 = $17.22
The data set represents a progression of hourly temperature measurements. Use a graphing calculator to determine the quadratic regression equation for this data set. X 0 1 2 3 4 5 y 20 16 10 0 -7 -20 a. Y = 0. 795 x squared 3. 796 x 20. 180 c. Y = negative 0. 875 x squared minus 3. 596 x 20. 179 b. Y = negative 0. 795 x squared minus 3. 760 x 20. 180 d. Y = negative 0. 795 x squared minus 3. 796 x 20. 180.
A regression can be modeled by linear regression, quadratic regression, quartic regression or exponential regression
The quadratic regression equation that models the data is
[tex]\^y = -0.875\^x^2 -3.596\^x +20.179[/tex]
How to determine the regression equationThe table entries are given as:
x: 0,1,2,3,4,5
y: 20,16,10,0,-7,-20
A quadratic regression is represented as:
[tex]\^y = a\^x^2 + b\^x + c[/tex]
Using a graphing calculator to determine the quadratic regression equation, we have the following calculation summary
a = -0.875
b = -3.596
c = 20.179
Hence, the quadratic regression equation is:
[tex]\^y = -0.875\^x^2 -3.596\^x +20.179[/tex]

Coach Brown had to buy baseballs for his team. He bought practice baseballs at $1.75 each, rubber pitching machine balls at $2.80 each, and leather game balls at $6.25 each. He bought 250 balls in total, and 20 fewer game balls than pitching machine balls.
If the total came to $974.65, then how many of each ball were ordered?
A. 130 practice, 113 machine, and 93 game balls
B. 44 practice, 113 machine, and 93 game balls
C. 206 practice, 113 machine, and 93 game balls
D. 114 practice, 113 machine, and 73 game balls
44 practice, 113 machine, and 93 game balls
===========================================================
Explanation:
x = number of practice baseballsy = number of pitching machine baseballsz = number of game ballsHe bought 20 fewer game balls than pitching machine baseballs, which means,
z = y-20
Since the coach bought 250 baseballs total we can also write
x+y+z = 250
Let's replace z with y-20 and simplify
x+y+z = 250
x+y+y-20 = 250
x+2y = 250+20
x+2y = 270
Now let's calculate the subtotal costs for each type of baseball
1.75x = cost of just the practice baseballs2.80y = cost of just the pitching machine baseballs6.25z = cost of just the leather game balls.Those subtotals add to this
1.75x+2.80y+6.25z = total cost = $974.65
1.75x+2.80y+6.25z = 974.65
Like before, I'll replace z with y-20
1.75x+2.80y+6.25(y-20) = 974.65
1.75x+2.80y+6.25y-125 = 974.65
1.75x+9.05y = 974.65+125
1.75x+9.05y = 1099.65
------------------------------
So far we have this system of equations
[tex]\begin{cases}x+2y = 270\\1.75x+9.05y = 1099.65\end{cases}[/tex]
I'll use substitution to solve the system.
Isolate x in equation (1)
x+2y = 270
x = 270-2y
Then plug this into equation (2) and solve for y.
1.75x+9.05y = 1099.65
1.75(270-2y)+9.05y = 1099.65
472.5-3.5y+9.05y = 1099.65
472.5+5.55y = 1099.65
5.55y = 1099.65-472.5
5.55y = 627.15
y = 627.15/5.55
y = 113
There are 113 pitching machine baseballs.
Use this y value to find x
x = 270-2y
x = 270-2(113)
x = 270-226
x = 44
There are 44 practice baseballs.
Also, we can say,
z = y-20
z = 113-20
z = 93
There are 93 game balls.
------------------------------
Check:
x+y+z = 44+113+93 = 250 baseballs total
A = 1.75*x = 1.75*44 = 77 = cost of just the practice baseballsB = 2.80*y = 2.80*113 = 316.40 = cost of just the pitching machine baseballsC = 6.25*z = 6.25*93 = 581.25 = cost of just the game ballsA+B+C = 77+316.40+581.25 = 974.65 = total cost
Everything checks out. Also note that value of z is 20 fewer than the value of y.
Which angles are complementary to each other?
Answer:
All apply
Step-by-step explanation:
Complementary angles are ones that total 90°. Here, we have two pairs of congruent angles such that each pair totals 90°. We can mix and match to find pairs of complementary angles.
less than 45°: BGC and EGF
more than 45°: AGB and DGE
A complementary pair will consist of one angle from the first list and one angle from the second list. There are 4 possible pairings, and all are shown as answer choices.
All of the choices apply.
A bike was recently marked down $200. 00 from its initial price. If you have a coupon for an additional 30% off after the markdown, how much will the bike cost if it was originally $950. 00?.
Percentage is represented by '%' symbol. The final cost of the bike will be equal to $490.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
Given to us
The initial cost of the bike, P = $950
Additional coupon = 30%
Marked down = $200
We know the original cost of the bike which is $950. therefore, when the price of the bike was marked down, its cost will be,
$900 - $200 = $700
Thus, the marked-down cost of the bike will be $700.
As it is given that we have an additional 30% off after the markdown, therefore, cost of the bike will be 70% of the marked price,
[tex]70\%\ of\ \$700\\\\ = 0.70 \times 700\\\\= \$490[/tex]
Hence, the final cost of the bike will be equal to $490.

Which of the following equations has both -5 and 5 as possible values of z?
z^2 =36
z^3 = 125
none of the above
The correct answer is z can take on the values of both -6 and 6, not -5 and 5.
The equation that has both -5 and 5 as possible values of z is:
[tex]z^2 = 36[/tex]
When we solve this equation, taking the square root of both sides, we get:
z = ±6
Therefore, z can take on the values of both -6 and 6, not -5 and 5.
Hence, none of the given equations have both -5 and 5 as possible values of z.For the equation z^2 = 36, we need to find the values of z that satisfy the equation. Taking the square root of both sides, we get:
z = ±√36
Simplifying the square root of 36, we have:
z = ±6
This means that z can take on the values of both -6 and 6. However, the values -5 and 5 are not solutions to this equation.
Similarly, for the equation z^3 = 125, there are no values of z that satisfy the equation for z equal to -5 or 5.
Therefore, none of the given equations, z^2 = 36 and z^3 = 125, have both -5 and 5 as possible values of z.

The exponent outside parentheses multiplies all of the exponents inside parentheses.

Additional comment
When it comes to exponents, I find it useful to remember that an exponent signifies repeated multiplication: x·x·x = x³. The exponent outside parentheses has the same meaning:
(x³)² = (x·x·x)·(x·x·x) = x⁶

b. Hot Spot
c. Sedimentary Rock
d. Continental Crust
e. Seafloor Crust
f. Fault
g. Fubduction
Seafloor spreading can be defined as a process that involves the formation of new oceanic crust as a result of volcanic activities and an upwelling of molten magma at mid-ocean ridges, as well as a slowly increasing distance (outward movement) from the ridge.
The theory of seafloor spreading was established by Harry Hammond Hess and it can be used to explain in details the slowly increasing distance between South America and Africa which grows from the center.
What is a hot spot?A hot spot refers to an area deep within Earth's mantle or under the rocky outermost layer of Earth, from which heat rises through convection and acquired as heat energy by a landform.
In the United States of America, you will see a layered sedimentary rock that is exposed by erosion when you view the Grand Canyon.
Furthermore, Australia is made up of relatively old and thick continental crust. Also, subduction causes the formation of extremely deep ocean Marianas Trench.
