Find the value of x!!!!!
Answer:
96 degrees
Step-by-step explanation:
The 144 degrees is on a straight line, meaning the angle next to it inside the triangle and 144 are supplementary. They add up to 180 degrees.
Coincidentally, the other two angles plus the third, unlabeled angle will add up to 180 degrees as well, meaning that the the 48+x = 144 degrees (according the property of equality, which is if a=b and b=c, then a=c). Solve for x from there:
x = 144-48
x = 96

Annie needs $30 to buy a coat she has saved $12 and plans to work as a baby siter to earn $6 per hour which inequality shows the minimum number of hours, n, that annie should work as a babysitter to earn enough to buy a coat?
a 12 + 6n ≤ 30, so n ≤ 3
b 12 + 6n ≥ 30, so n ≤ 3
c 6n ≥30 + 12, so n ≥ 7
d 6n ≤30 + 12, so n ≤ 7
Answer:
The answer would be B.
Step-by-step explanation:
This is because the total cost is $30 so it can't be c or d. A shows that Annie can only have at least $30. this means that B is the only option left.

A cake is removed from an oven. The temperature, in degrees Fahrenheit, of the cake after t minutes can be modeled by the equation, f(x)=70+140e^-0.024t.
What is the temperature of the cake at the moment it is removed from the oven and about how long will it take for the cake to reach a temperature of 80F ? Round your answer to the nearest whole minute.
Thank you (:

Answer:
210 °F110 minutesStep-by-step explanation:
A graphing calculator answers the questions easily.
At t=0, f(0) = 210 . . . degrees F
f(t) = 80 at about t=109.96, so it takes about 110 minutes to reach 80 °F.
__\
Working "by hand"
The exponential term is 1 at t=0, so the temperature then is ...
f(0) = 70 +140·1 = 210 . . . degrees F
The temperature of the cake from the oven is 210 °F.
__
The time when the temperature is 80 °F will be ...
80 = 70 +140e^(-.024t)
10 = 140e^(-.024t)
10/140 = e^(-.024t)
ln(1/14) = -0.024t
t = ln(1/14)/-0.024 ≈ 109.9607
t ≈ 110 when f(t) = 80
It takes about 110 minutes for the cake to cool to 80 °F.

What single percentage change is equivalent to a 8% increase followed by a 15% increase?
Answer:
24.2%
Step-by-step explanation:
If we take 100 for example, an 8% increase would make it 108, and a further 15% increase would make it 124.2 and 124.2 is 124.2% of 100 and if we minus the initial value of 100% it would be 24.2%

The Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep. How many feet deeper is the Mariana Trench than the Puerto Rico Trench?
Answer:
8708 feet
Step-by-step explanation:
The Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep.
We need to find how many feet deeper is the Mariana Trench than the Puerto Rico Trench.
As Mariana Trench and Puerto Rico Trench is deep.
h = -27,493-(-36,201)
h = 8708 feet
So, Mariana Trench is 8708 feet deeper than Puerto Rico Trench

pls help me 98+29 x=96+33x
Answer:
x=1/2
Step-by-step explanation:
98+29x=96+33x
Step 1: Simplify both sides of the equation.
29x+98=33x+96
Step 2: Subtract 33x from both sides.
29x+98−33x=33x+96−33x
−4x+98=96
Step 3: Subtract 98 from both sides.
−4x+98−98=96−98
−4x=−2
Step 4: Divide both sides by -4.
−4x
−4
=
−2/−4

n is an integer.
Write the values of n such that -15 < 3n<6
Answer:
(-1,-2, -3, -4)
Step-by-step explanation:
-15 < 3n <6
-15 < 3 (-1,-2, -3, -4) <6
3 • -1 = -3
3 • -2 = -6
3 • -3= - 9
3 • -4 = -12
so all these answer still make -15 the lowest value and 6 the highest value.
