Answer:
Step-by-step explanation:
The formula u have written is incorrect. It should be C = [5 (F-32)]÷9.
To identify which is hotter, you need to bring both the values either in celsius or in Fahrenheit.
Let's convert 85°F to celsius:
C = [5 ( F - 32 )] ÷ 9
C = [5 ( 85-32 )] ÷ 9
C = [5 (53)] ÷ 9
C = 29.4 °C
thus 30°C is hotter than 85°F
An online music store is offering a promotion. When you spend $45 or more, you receive 3 songs for free. You buy an album for $15. Identify the inequality that represents how much more money m you must spend to receive the three free songs.
Answer: x ≥ $30.
Where x is the amount of money that you need to spend if you want to have the 3 free songs.
Step-by-step explanation:
When you spend $45 or more, you get 3 free songs.
You already bought an album that costs $15, then the minimum amount that you need to spend is (when you spend exactly $45):
$45 - $15 = x = $30.
Then the inequality is:
x ≥ $30.
Because if you spend more than $45 you also get the songs.

Problem 4:
The hypotenuse of a right angled triangle is 20 cm. The difference between its other two sides is 4 cm. Find the length of the sides.
Answer:
12cm and 16cm
Step-by-step explanation:
The hypotenuse of the right angle triangle = 20cm
let the other two sides be x and y;
The difference;
x = y - 4
Problem:
Find x and y;
Solution:
According to the pythagoras theorem;
x² + y² = 20² ------ i
x² + y² = 400 ----- i
and x - y = 4 ---- ii
So; x = 4 + y
Now input the value into equation (i);
(y + 4)² + y² = 400
(y+4)(y+4) + y² = 400
y² + y² + 4y + 4y + 16 = 400
2y² + 8y + 16 = 400
2y² + 8y + 16 -400 = 0
2y² + 8y - 384 = 0;
y² + 4y - 192 = 0
Factorize the equation;
y² + 16y - 12y - 192 = 0
y(y + 16) - 12(y + 16) = 0
(y-12)(y + 16) = 0
y -12 = 0 or y+ 16 = 0
y = 12 or -16
It is not realistic for the length of a body to be a negative value, so y= 12;
since;
x - y = 4,
x = 4 + 12
x = 16

Answer:
see below
Step-by-step explanation:
x+ 7.05 = 45.3
Subtract 7.05 from each side
x+ 7.05-7.05 = 45.3-7.05
x =38.25
Let x be the number
x+3.5 = -4.3
Subtract 3.5 from each side
x+3.5 - 3.5 = -4.3-3.5
x = -7.8
x is the cost of the drawing tablet
x+ 3.95 = 6.94 correct
The second equation add the total cost plus the cost of the drawing tablet and sets it equal to the cost of the pencils. This is not correct
6.94+x = 3.95 incorrect
Answer:
1. x=38.25
2. -7.8
3. the second option
Step-by-step explanation:
1. x+7.05=45.3
(move the constant to the right)
x=45.3-7.05
(calculate)
x= 38.25
(answer)
2.
(you subtract -4.3 by 3.5)
3.
(you can't use $6.94 + x = $3.95 because $6.94 is your total overall so you can only use that as your end result)

What is the answer of question 17 in lesson 2.1 translations
9514 1404 393
Answer:
y = 2x(1, 2)Step-by-step explanation:
The line representing Murphy street goes through point (0, 3) and has a slope of 2/1 = 2. Its equation is then ...
y = mx + b
y = 2x +3
The translation vector transforms this equation* by adding -1 to y, and replacing x with x-1.
y = (2(x-1)) +3) -1
y = 2x -2 +3 -1 . . . . eliminate parentheses
y = 2x . . . . . . . . . . . the equation for Nolan street
__
Of course, adding (1, -1) to the point (0, 3) moves it to ...
(1, -1) +(0, 3) = (0+1, -1+3) = (1, 2)
The image of (0, 3) is (1, 2).
_____
* f(x) is translated by (a, b) this way: g(x) = f(x-a) +b. Here, f(x) = 2x+3 is translated to f(x-1)+(-1) = (2(x-1) +3) -1.

Answer:
-1
Step-by-step explanation:
The mean is the sum of all values divided by the amount of values.
We take the sum of all the numbers:
-3 + -8 + 12 + -15 + 9
-11 + 12 + -15 + 9
1 + -15 + 9
10 + -15
-5
We then divide the sum by how many number we have (we are given 5 numbers):
-5/5 = -1
Therefore, our mean is equal to -1.
Answer:
-1
Step-by-step explanation:
-3 + -8 + 12 + -15 + 9 = -5 Now divide it by the amount of numbers given. -5 / 5 = -1

Use the divisibility rules to determine which of the following numbers 315 is divisible by.(Check all that apply.)
-2
-3
-5
-7
-11
Answer: 3, 5, 7
Step-by-step explanation:
There is a "trick" to determine divisibility by 3: if the sum of the digits is divisible by 3, the number is divisible by 3.
3 + 1 + 5 = 9 which is a multiple of 3, so 315 is divisible by 3.
It works for 9 also. since the sum of the digits is 9, 315 is divisible by 9.
Divisibility by 5: any number that has the units digit 5 or 0 is divisible by 5.
For 7, I just tried it 315÷7= 45
Only even numbers are divisible by 2.
If a 3-digit number is divisible by 11, the middle digit will be the sum of the first and last digits. (That is not the case for 315) But 385 is divisible by 11, also 495, 253, and many others you can try for fun.

.Rahul and his wife work in Mohan's farm. The Government has declared that the farm workers should be paid Rs. 71 for a day's work. But the land lord, Mohan pays Rs. 60 for Rahul and Rs.55 to his wife. If Rahul works for 55 days and his wife for 40 days, what amount of money will they earn together?
Answer:
Rs. 5500
Step-by-step explanation:
The government has declared that farm workers should be paid Rs. 71 for a day's work
The landlord Mohan pays Rahul Rs. 60 and pays Rs. 55 to his wife
Rahul works for 55 days
= 60 × 55
= Rs. 3,300
His wife works for 40 days
= 55 ×40
= Rs. 2,200
Therefore the total amount of money earned together can be calculated as follows
= 3300 + 2200
= Rs. 5500
Hence they will earn Rs. 5500 together

For a data set of weights? (pounds) and highway fuel consumption amounts? (mpg) of eight types of? automobile, the linear correlation coefficient is found and the? P-value is 0.001. Write a statement that interprets the? P-value and includes a conclusion about linear correlation.The? P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is nothing?%, which is ? low, high, so there ? is not is sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles
Answer:
The correct option is;
Low
Step-by-step explanation:
Given that the P-value of the linear correlation = 0.001, we have that the P-value is a demonstration that a linear correlation that has a value in the range of the given correlation is ,most arguably very low
From the z-table, a P-value of 0.001 corresponds to a z-value of -3.09, we have that in a normal distribution since 95% of the scores have a z-score of between -2 and 2, the z-score of -3.09 is very distant from the mean and having a low value, whereby the P-value shows that the likelihood of finding another linear correlation that is as far from the mean as the given correlation is very low.
The city council budgeted $2,784 to buy new garbage cans. If each garbage can costs $96,
how many garbage cans will the city be able to buy?
Answer:
29 trash cans!
Step-by-step explanation:
Hello!
To solve this, we simply divide the budget by how much each garbage can costs. This will tell us how many times 96 goes into 2,784, and thus, how many they can buy.
$2,784 ÷ $96 = 29!
So, they can buy 29 trash cans with that budget!
