One night, it is 24 ℃ warmer in Tucson than it was in Minneapolis. If the temperatures in Tucson and Minneapolis are opposites, what is the temperature in Tucson?
Answers
Answer:
The temperature in Tucson is [tex]12\,^{\circ}C[/tex].
Step-by-step explanation:
Let be [tex]T[/tex] and [tex]-T[/tex] the temperatures registered in Tucson and Minneapolis, respectively. The difference between both temperatures is:
[tex]T - (-T) = 24\,^{\circ}C[/tex]
[tex]2\cdot T = 24\,^{\circ}C[/tex]
[tex]T = 12\,^{\circ}C[/tex]
The temperature in Tucson is [tex]12\,^{\circ}C[/tex].
Answer:
The temperature in Tucson is 12°C, and that of Minneapolis is -12°C.
Step-by-step explanation:
Let the temperature in Tucson = T
And the temperature in Minneapolis = -T. Because the temperatures are opposites.
Since we know that it is 24°C warmer in Tucson that it was in Minneapolis, then
T - (-T) = 24
T + T = 24
2T = 24
T = 24/2
= 12
Therefore, the temperature in Tucson is 12°C, and that of Minneapolis is -12°C.

Isaac is constructing a circular pool that has a diameter of 20 ft and is 5 ft deep. Part A: Find the circumference of the pool to the nearest tenth of a foot. Use 3.14 for pi. Part B: Find the area of the circle formed by the pool to the nearest foot.
Answers
Answer:
The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².
Step-by-step explanation:
The circumference of the pool can be found by calculating the arc's length of the edges of the pool. This is done by using the following formula:
[tex]circumference = 2*\pi*r[/tex]
Where the radius is half the diameter, applying the data from the problem we have:
[tex]circumference = 2*3.14*10 = 62.8 \text{ ft}[/tex]
The area of the circle formed by the pool can be found using the following expression:
[tex]area = pi*r^2 = 3.14*(10)^2 = 314 \text{ ft}^2[/tex]
The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².
The weights of the cars passing over a bridge have a mean 3,550 pounds and standard deviation of 870 pounds. Assume that the weights of the cars passing over the bridge are normally distributed. Use the empirical rule to estimate the percentage of cars over the bridge whose weights are between 1810 and 4420 lbs.
a. 13.5%
b. 81.5%
c. 68%
d. 95%
Answers
Mean = 3550
SD = 870
Find P(1810 <x<4420)
z = x -mean / sd
= (1810 - 3550 / 870) < z< (4420 - 3550 / 870)
= -2 <z< 1
Using the -z table -2 = 0.0228 and 1 = 0.8413
Subtract: 0.8413 - 0.0228 = 0.8185 x 100 = 81.85%
Rounding everything may change answer slightly so
The closest one is B 81.5%

Tyron made 60 cakes. He gave 1/6 of the 60 cakes to Lilly. What fraction of the cakes does he have left?
Answers
Answer:
38/60 or 19/30
Step-by-step explanation:
The question isn't fully attached as stated by the person who submitted it.
The fraction of the cakes he has left is ( 5 / 6 ). The remaining number of cakes is 50.
What is a fraction?Expression in maths is defined as the collection of numbers, variables, and functions using signs like addition, subtraction, multiplication and division.
The fraction is calculated as:-
The remaining fraction = 1 - ( 1 / 6 )
= ( 6 - 1 ) / 6
= 5 / 6
The remaining number of cakes,
Remaining number = 60 x ( 5 / 6 )
Remaining number = 50
Hence, the remaining number of cakes is 50.

What is the equation of the line of best fit for the following data round the slope and Y intercept of the line to three dimensional places. Please help ASAP thank you so much.
Answers
Answer:
y = 1.56 x - 4.105
which agrees with answer "B" in your list of possible options.
Step-by-step explanation:
Notice that you are expected to use some type of regression tool for this problem. either a computer program or a handheld graphing calculator with such functionality.
I have entered the set of data points in two separate lists, one for the x-values,and another one for the y-values, and run the linear regression tool in order to get the best fitting line. See what I obtained using this tool in the screen capture I am attaching below.
Notice that the line of best fit reads:
y = 1.56015038 x - 4.10526316
showing clearly the slope and y-intercept of the line of best fit.
Rounding slope and y-intercept to the third decimal, we get:
y = 1.56 x - 4.105
which agrees with answer "B" in your list of possible options.

Answers
Answer:
H(t) = -10·cos(t/20) +20
Step-by-step explanation:
The range of heights is ...
30 m - 10 m = 20 m
The amplitude of the cosine function is half that, or 10 m. Here, the function starts off at a minimum, whereas the parent cosine function starts at a maximum. That means the parent function is reflected vertically, so the amplitude coefficient in H(t) is negative.
The midline of the cosine function is the average of the extreme heights, so is ...
midline = (30 m +10 m)/2 = 20 m
The period of the function is double the time it takes to go from a minimum to a maximum, so is ...
p = 2(20π) = 40π . . . . seconds
In the given function form ...
H(t) = a·cos(bt) +d
the amplitude is a=-10; the coefficient b is 2π/p = 1/20; and the midline is d = 20. Then the function is ...
H(t) = -10·cos(t/20) +20

What is the area of the given compound shape?
1. 19 sq cm
2. 25 sq cm
3. 34 sq cm
Answers
Answer:
(A)
Step-by-step explanation:
As you can see, the figure can be divided into a square of side 2cm and a rectangle of sides 5cm and 3cm so we find the area of both and add.
Area of the square
= 2x2 = 4cm^2
Area of the rectangle
= lxb
= 3x5
= 15 cm^2
Therefore the area of the entire figure
= Area of square + area of rectangle
= 15+4
= 19 cm^2
So the correct option is (a)

Consider this system of linear equations: y = –3x + 5 y = mx + b Which values of m and b will create a system of linear equations with no solution?
Answers
Answer:
m = - 3 and b = - 3.
Step-by-step explanation:
A system of linear equations will not have solutions if the two lines are parallel.
Two equations are parallel:
1. if their slopes (m) are equal
2. the y-intercep (b) are different.
As y = - 3x + 5, the value of m of the other equation, y = mx + b, in order to make a system with no solution, needs to be - 3, and the value of b need to be different to 5.
The only pair from the choices that meets that is the first option m = - 3 and b = -3.
Answer:
m = -3, b = 5
Step-by-step explanation:
The values m = -3 and b = 5, forms a linear equation: y = -3x + 5. This obviously coincides with the original equation given, and so will create a system of linear equations with no solution.
