On Tuesday morning, the temperature is -5º F. The temperature rises 3 4 degree each hour for 6 hours before dropping 1 4 degree each hour for 3 hours. What is the temperature, in degrees Fahrenheit, after 9 hours?
Answer:
The temperature in degrees after 9 hours is -1.25 degrees Fahrenheit
Step-by-step explanation:
Here, we want to know the temperature after 9 hours
Per hour rise each hour is 3/4 degree = 0.75 degree
In 6 hours that will be 0.75 * 6 = 4.5 degrees
Or hour drop is 1/4 = 0.25 degree
In 3 hours, that will be 0.25 * 3 = 0.75 degree
Since it is a drop, we have -0.75 degree
Temperature after 9 hours will be;
-5 + 4.5 -0.75
= -5.75 + 4.5 = -1.25 degrees fahrenheit

How can we get Equation B from Equation A?
3(x+2)=18
x+2=18
i need them solved aswell
Answer:
x = 4
Step-by-step explanation:
A:3(x+2)=18
Divide each side by 3
3/3(x+2)=18/3
x+2 = 6
This is the same equation as equation B
They will have the same solution since they are the same equation
x+2-2 = 6-2
x = 4
(not my answer)
if you could help me with this i would be very thankful
Answer:
Δ QRS is an obtuse triangle ⇒ according to its angle
Δ QRS is an isosceles triangle ⇒ according to its sides
Step-by-step explanation:
In Δ QRS
∵ m∠Q = 8x - 17
∵ m∠R = 19x + 4
∵ m∠S = 5x + 1
→ The sum of the interior angles of a Δ is 180°
∴ m∠Q + m∠R + m∠S = 180°
→ Substitute their values in the equation above
∵ 8x - 17 + 19x + 4 + 5x + 1 = 180
→ Add the like terms
∴ (8x + 19x + 5x) + (-17 + 4 + 1) = 180
∴ 32x + (-12) = 180
∴ 32x - 12 = 180
→ Add 12 to both sides
∵ 32x - 12 + 12 = 180 + 12
∴ 32x = 192
→ Divide both sides by 32
∵ [tex]\frac{32x}{32}[/tex] = [tex]\frac{192}{32}[/tex]
∴ x = 6
→ Substitute the value of x in each measure of angles to find them
∵ m∠Q = 8(6) - 17 = 48 - 17
∴ m∠Q = 31°
∵ m∠R = 19(6) + 4 = 114 + 4
∴ m∠R = 118°
∵ m∠S = 5(6) + 1 = 30 + 1
∴ m∠S = 31°
∵ m∠R > 90°
∴ ∠R is an obtuse angle
∴ Δ QRS is an obtuse triangle
∵ m∠Q = m∠S
→ In any Δ if two angles are equal in measures, then the two sides
opposite to these angles are equal in length and the Δ is isosceles
∴ RQ = RS
∴ Δ QRS is an isosceles triangle

-8а - 5 = 3 - 6а
Answer:
-8a-5=3-6a
-8a+6a=3+5
-2a=8
a=8/-2
therefore,a=-4 answer...
Answer:
a = 4
Step-by-step explanation:
Firstly, make all subtraction signs, addition signs which should look like this
-8a + -5 = 3 + -6a
Add 5 to both, -5 and 3.
-8a = 8 + -6a
Add 8a to both -8a and -6a
2a = 8
Divide both by 2
a = 4
Your making chocolate chip cookies. The recipe calls for 1/8 teaspoon salt to 1/4 teaspoon baking soda. How much salt is needed for one teaspoon of baking soda
Answer:
Step-by-step explanation:
this ratio of (1/8) to (1/4) can be written as a fraction
however, since we want to find out how much salt is needed for one teaspoon of baking soda, salt is the numerator (top) of the fraction and baking soda is the denominator (bottom) of the fraction
(1/8)/(1/4)
(1/8)x(4/1) when you divide fractions the second fraction switches the top and bottom
(1/8)x4
4/8
1/2
1/2 or 0.5 teaspoons of salt are needed per teaspoon of baking soda

5. Noah and his friends are going to an amusement park. The total cost of admission for 8
students is $100, and all students share the cost equally. Noah brought $13 for his
ticket. Did he bring enough money to get into the park? Explain your reasoning.
Answer:
yes
Step-by-step explanation:
he did because 100 divided by 8 is 12.5 and that would equal $12.50
So in all he would have 50 cents left
Answer:
yes,Noah did bring enough money for the ticket.
Step-by-step explanation:
you know that it's going to 8 students and in total it's 100.You need to know how much each will need to pay so you divide 100 divided by 8.The quotient/answer to what each student will pay is 12.5. 13 dollars is more than enough to pay for the ticket so Noah did bring enough.

I have 5 digits. My q is worth q * 10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am l
Answer:
92,776
Step-by-step explanation:
I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?
My 9 is worth 9*10,000 = 9 * 10,000
= 90,000
My 2 is worth 2 thousand = 2,000
One of my 7s is worth 70 = 70
The other is worth 10 times as much = 70 * 10
= 700
My other digit is a 6 = 6
The number is
90,000 + 2,000 + 700 + 70 + 6
= 92,776

|xl = 5 determine possible values
Answer:
5 and -5
Step-by-step explanation:
The absolute value of a number is how far away the number is from zero and the absolute value is always positive.
If f(a)=-5, what is the value of |f(a)|?
|f(a)| , the vertical lines mean absolute value. Absolute value is the positive value of the answer whether it is actually negative or positive.
F(a) is given as -5, so the absolute answer would be 5
The answer is 5
solve for the missing side

1. In the office, there is a filing cabinet that is 1 foot wide, 3 feet deep and 3
feet tall. You have hundreds of file folders to put into this cabinet.
Assuming that each folder is 12 inches wide, 1 inch thick, and 9 inches
tall, how many folders can you fit into this cabinet? (Draw a picture!)
Answer:
the answer is 144 folders
Step-by-step explanation:
you have to convert the ft of the file cabinet to inches. so the cabinet is 12 in wide, 36 in deep and 36 in tall. the volume of it is 15,552 cu in. each folder is 108 cu in. divide 15,552 by 108 = 144 folders can fit in the cabinet. sorry my pic is messy.

James and Ahmik went to a bicycle show. Of the bicycles they saw at the show, 32% were blue, 25% were red, 25% were green, and 18% were black. In ratio form, what percent of the bicycles were red or black?
Answer: 43:100
Step-by-step explanation:
Percentage of bicycles that are blue = 32%
Percentage of bicycles that are red = 25%
Percentage of bicycles that are green = 25%
Percentage of bicycles that are black = 18%
Percentage of bicycles that are red or black = 25% + 18% = 43%
Therefore, 43% will be written in ratio form as 43:100
