Answer: it should be 5
Step-by-step explanation: if 3 3/4 divided into three parts its 1 1/4. If we add 3 3/4 and 1 1/4, then we have 5
The rate of rise in temperature in degrees per hour will be equal to 5° per hour.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.
Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given information in the question,
The temperature rise of the compound to 3 3/4° every 3/4 of an hour.
1 hour = 60 minutes then,
3/4 of an hour = 3/4 × 60 = 45 minutes.
(15/4)° rise in 45 minutes or,
3.75° rise in 45 minutes.
Let the rise in temperature in 1 hour will be x° then,
x = (3.75 × 60)/45
x = 5° per hour.

Answer:
for the first one I got y=-2x-2 the second part i got y=-x-1 or -1x-y-1=0 Correct me if I am wrong
Step-by-step explanation:
Use the slope formula
-4-4 =-8
/ =-2
1 - -3=4
2. The second part use this formula y-y1=m(x-x1)
y--4=-1(x-3)
y+4=-x+3

A sailor is allowed 7 days off for every 30 days at sea. For 28 days off, how many days at sea must the sailor spend?
Answer:
120 days
Step-by-step explanation:
7 days off x 4 days off = 28 days off, so you have to multiply 30 x 4 which equals 120
Find the length of the shorter leg of a right triangle if the longer leg is 15 feet more than the shorter leg and the hypotenuse is 15 feet less than twice the shorter leg
Answer:
45
Step-by-step explanation:
Let the length of the shorter leg be represented as x.
Let the length of the longer let let be represented as x+15
While the length of the hypotenuse be 2x-15.
From the knowledge of phythagoras theorem:
x^2+(x+15)^2 = (2x-15)^2
x^2+x^2+15x+15x+225 = 4x^2-30x-30x+225
2x^2+30x+225 = 4x^2-60x+225
2x^2-4x^2+30x+60x+225-225=0
-2x^2+90x+0= 0
2x^2-90x = 0
Divide through by 2
x^2-45x=0
x(x-45)=0
x = 0 or x-45=0
Considering x-45=0
x-45=0
x = 45
If x is for the shorter leg,
The length for the longer leg is: x+15
= 45+15
= 60
For the hypotenuse = 2x-15
= 2×45-15
= 90-15
= 75

Show work
Answer:
7x-4+x=-1+13x+7
8x-4=13x+6
add 4 to both sides
8x-4+4=13x+6+4
8x=13x+10
subtract 13x from both sides
8x-13x=13x+10-13x
-5x=10
divide both sides by -5
-5x÷-5=10÷-5
x=-2

If these numbers represent elevations in meters, which is the farthest away from sea level?
Answer:
Option (1)
Step-by-step explanation:
Minus notation of the elevations from the sea level represents the distance below the sea level and positive notation represents the elevations above the sea level.
+7 → 7 meters above the sea level
-3 → 3 meters below the sea level
[tex]+\frac{1}{2}[/tex] → 0.5 meters above the sea level
-0.8 → 0.8 meters below the sea level
+0.8 → 0.8 meters above the sea level
[tex]-\frac{1}{10}[/tex] → 0.1 meters below the sea level
-2 → 2 meters below the sea level
Therefore, +7 meters above the sea level will be the farthest point from the sea level.
Option (1) will be the answer.

Jerry purchases a used sofa for $275. He cleans and reupholsters the sofa to make it look brand new. After all the improvements, Jerry sells the sofa for 40% more than what he originally purchased it for. What was the profit Jerry made after selling the sofa?
Answer:
$110Step-by-step explanation:
Step one:
we are told that the cost of the sofa is $275
also, he sells it for 40% more of the cost price
let us find 40% of $275
=40/100*275
=0.4*275
=110
=$110
Step two:
This means that the selling price is 275+110
=$385
profit = selling price- cost price
profit=385-275
profit=$110
Simplify the following expression. (19x + 4y) + (49x + 32y)
Answer: 68x + 36y
Step-by-step explanation:
Combine Like Terms:
= 19x + 4y + 49x + 32y
= (19x + 49x) + (4y + 32y)
= 68x + 36y
Hope this helped you!
Answer:
68x + 36y
Step-by-step explanation:
You can compeletely get rid of the parenthesis because it is addition through and thorough.
You have 19x + 4y + 49x + 32y
You can combine like terms to get
19x +49x which is 68x
and
4y + 32y which is 36y
You now have 68 + 36y which cannot be simplified anymore because the variables are different.
Hope this helps!

A school group has $140 to spend. Write and solve an inequality that represents the cost to rent the main hall, where h represents the number of hours the group can rent the room.
Answer:
a. 15h + 40 ≤ 140
b. h ≤ 6.6
Note: The question is missing a table. The table is shown in the attachment below.
Step-by-step explanation:
a. The school group has $140 to spend, and so can only spend an amount less than or equal to $140 when renting the main hall.
The cost of renting the main includes an hourly rate of $15 and a set-up fee of $40.
Let h represent the number of hours the group can rent the hall.
Cost of renting the main hall, C is given by:
15h + 40 ≤ 140
b. Solution of the inequality:
15h + 40 ≤ 140
15h ≤ 140 - 40
15h ≤ 100
h ≤ 100/15
h ≤ 6.6
Therefore, the main hall can only be rented for a maximum of 6.6 hours or less

What is the value of M ?
Answer:
m = 124 degrees.
Step-by-step explanation:
The sum of the interior angles of a triangle is 180.
The angle opposite m + 56 + 68 = 180.
The angle opposite m = 56.
The angle opposite m + m = 180, so 56 + m = 180.
Angle m = 124.
