Answer:
The answer is "She cut a total of 42 pieces of pie".
Step-by-step explanation:
Given :
Total pie= [tex]5 \frac{1}{4}[/tex]
cut pie = [tex]\frac{1}{8}[/tex]
The number of pieces of the pie she has=?
Solve the mixed fraction value:
[tex]\to 5 \frac{1}{4}= \frac{21}{4}[/tex]
If she cuts the pieces into the entire pie, that is = [tex]\frac{1}{8}[/tex]
So, the equation is:
[tex]\to \frac{21}{4} = \frac{1}{8} \times x[/tex]
[tex]\to x= \frac{21 \times 8}{4}\\\\ \to x= 21 \times 2\\\\ \to x=42[/tex]

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.

What value of a will yield a solution of (2,8) for the system?
y = ax
ax + y = 16
Answer:
The value of a is 4 ⇒ D
Step-by-step explanation:
In the system of equations
∵ y = ax ⇒ (1)
∵ ax + y = 16 ⇒ (2)
∵ The solution of the system is (2, 8)
∴ x = 2 and y = 8
→ To find the value of a substitute x by 2 and y by 8 in equation (1) or (2)
∵ y = ax
∵ y = 8 and x = 2
∴ 8 = a(2)
∴ 8 = 2a
→ Divide both sides by 2
∵ [tex]\frac{8}{2}[/tex] = [tex]\frac{2a}{2}[/tex]
∴ 4 = a
∴ The value of a is 4

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
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

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.

You have 784 grams of a radioactive kind of tellurium. If its half-life is 42 minutes, how much will be left after 126 minutes?
Answer:
98 grams
Step-by-step explanation:
The simplest way to think about this is that the half life has elapsed 3 times, so you need to take the initial mass and divide it by 2 3 times, so 784/2/2/2 or 784/8 which is 98

Answer:
Interpolation refers to using the data in order to predict data within the dataset. Extrapolation is the use of the data set to predict beyond the data set.
Step-by-step explanation:
Extrapolation and interpolation are both used to estimate hypothetical values for a variable based on other observations. There are a variety of interpolation and extrapolation methods based on the overall trend that is observed in the data.
