One winter day, the temperature in Houston is 8 Celsius. Find the temperatures in these other cities. Explain or show your reasoning.
In Orlando, it is 17 warmer than it is in Houston
In Salt Lake City, it is 18 colder than it is in Houston
In Minneapolis, it is 25 colder than it is in Houston
In Fairbanks, it is 12 colder than it is in Minneapolis
Write an addition equation that represents the relationship between the temperature in Houston and the temperature in Fairbanks.
Answers
Salt Lake city = -10° because 8-18
Minneapolis = -17° because 8-25
Fairbanks = -29° because -17-12
Houston = 8° - 37° = Fairbanks
Hence, the temperatures in these other cities are
Orlando is [tex]25[/tex] degree
Salt Lake is [tex]-10[/tex] degree
Minneapolis is [tex]-17[/tex] degree
Fairbanks is [tex]-29[/tex] degree
What is the degree?
A degree, usually denoted by °, is a measurement of a plane angle in which one full rotation is [tex]360[/tex] degrees.
Here given that,
One winter day, the temperature in Houston is [tex]8[/tex] Celsius.
In Orlando, it is [tex]17[/tex] warmer than it is in Houston.
In Salt Lake City, it is [tex]18[/tex] colder than it is in Houston.
In Minneapolis, it is [tex]25[/tex] colder than it is in Houston.
In Fairbanks, it is [tex]12[/tex] colder than it is in Minneapolis.
So, it would be
Orlando = [tex]25[/tex] degree
because [tex]17+8=25[/tex] degree
Salt Lake city [tex]= -10[/tex] degree
because [tex]8-18=-10[/tex] degree
Minneapolis [tex]= -17[/tex] degree
because [tex]8-25=-17[/tex] degree
Fairbanks [tex]= -29[/tex] degree
because [tex]-17-12=-29[/tex] degree
Hence, the temperatures in these other cities are
Orlando is [tex]25[/tex] degree

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 4(m∠Y) − 210°. Find m∠Y.
Answers
Answer:
angle Y= 60 degrees
Step-by-step explanation:
angle S + angle Y = 90 degrees because they are complementary
Y = 90 - S
angle S = 4(Y)-210
substitute for Y
S = 4(90 - S) - 210
S = 360 - 4S - 210
reduce
5S = 150
S = 30
Y = 90 - 30 = 60

Write a rule for a function with a parabolic graph that contains the x-intercepts (-20,0) and (40,0) and a maximum point whose y-coordinate is 30.
Answers
Step-by-step explanation:
Since the x-intercepts are -20 and 40, the line of symmetry is x = (-20 + 40)/2 = 10.
Now we have y = a(x - 10)² + 30, where a is an unknown constant. We can find a by using an x-intercept point.
=> (0) = a[(40) - 10]² + 30
=> 900a + 30 = 0, a = -1/30.
Hence the rule is y = -(x - 10)²/30 + 30.
An article describes the chemical compositions of certain minerals in the early Archaean mantle. For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4. Find the mean and standard deviation of the sample mean SiO2 content in a random sample of 10 rocks. Round the mean to two decimal places. Mean Standard deviation
Answers
Answer:
The mean is 40.35 and the standard deviation is 0.13.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4.

By the Central Limit Theorem, the mean is 40.35, and the standard deviation is [tex]s = \frac{\sigma}{\sqrt{n}} = \frac{0.4}{\sqrt{10}} = 0.13[/tex]
The mean is 40.35 and the standard deviation is 0.13.

of clay. Each student got 1/2 of a
pound of clay to make a plate.
How many plates did the
students make?
Answers
Answer:
32 plates
Step-by-step explanation:
If the pottery class has 16 pounds of clay and each student got 1/2 of a pound;
then;
1 plate = 1/2 pounds
xplate = 16pounds
Divide both expressions
1/x = 1/2÷16
1/x = 1/2*!6
1/x = 1/32
x = 32

What is the probability of selecting a green shirt
Answers
Answer:
The probability is of selecting a green shirt is 8
Step-by-step explanation:
24 - 4 = 20
20 - 12 = 8
The probability of not selecting a white shirt is 2/3.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that a laundry basket has 24 t-shirts 4 are navy 12 are red and the rest are white
We have to find the probability of not selecting a white shirt
Total number of shirt's= 24
navy = 4
red = 12
white = 24 - ( 4+12)= 8 white shirts
number of shirts that are not white = 16
Therefore the probability of not selecting a white shirt = 16/24
= 2/3
Hence, the probability of not selecting a white shirt is 2/3.

the sum of two numbers is 51 and the difference is 13. what are the numbers
Answers
Answer:
Step-by-step explanation:
19 and 32
Answer:
the two numbers are 19 and 32
Step-by-step explanation:
let's call the numbers x and y.
write out the equations
x + y = 51
x - y = 13
simplify the second equation
x = 13 + y
substitute into the first equation and simplify
(13 + y) + y = 51
13 + 2y = 51
2y = 51 - 13
2y = 38
y = 19
substitute y for 19 in the second equation
x = 13 + y
x = 13 + 19
x = 32

Answers
9514 1404 393
Answer:
∠E = 156°
Step-by-step explanation:
The sum of angle measures in a pentagon is 540°, so we have ...
95 +(7x -4) +90 +(9x -6) +(3x +23) = 540
19x +198 = 540
19x = 342 . . . . . . . subtract 198
x = 18 . . . . . . . . . . .divide by 19
Then the measure of angle E is ...
∠E = (9x -6)° = (9·18 -6)°
∠E = 156°
