Answer:
210°F
110 minutes
Step-by-step explanation:
Given that :
Temperature of cake t minutes after being removed from oven :
f(x)=70+140e^-0.024t
Temperature T the timee it is removed ;
At this point, the time t = 0
f(t)=70+140e^-0.024t
f(x)=70+140e^-0.024(0)
= 70 + 140(1)
= 210°F
how long will it take for the cake to reach a temperature of 80oF
80 = 70+140e^-0.024t
80 - 70 = 140*e^-0.024t
10/140 = e^-0.024t
0.0714285 = e^-0.024t
In(0.0714285) = - 0.024t
−2.639057 = - 0.024t
t = 2.639057 / 0.024
t = 109.9607
t = 110 minutes

Someone help me find the answer please
Answer:
[tex]a^{3}[/tex] * [tex]b^{2}[/tex]
Step-by-step explanation:
[tex]\frac{a^{12} * b^{7} }{a^{9} * b^{5} }[/tex]
Divide the equation (split the equation into parts), to show like terms;
[tex]\frac{a^{12} }{a^{9} }[/tex] * [tex]\frac{b^{7} }{b^{5} }[/tex]
Since dividing two numbers with exponents,( that have the same base), is equivalent to subtracting the exponents and retaining the base, hence:
[tex]a^{3}[/tex] * [tex]b^{2}[/tex]

On Monday, George's checking account held $61.72. On Tuesday, he withdrew $57.00 from the account. On Thursday afternoon he deposited $197.27. What was his final balance Friday morning?
Answer:
$201.99
Step-by-step explanation:
Given that:
Amount held on Monday = $61.72
Amount withdrawn on Tuesday = $57.00
Amount deposited on Thursday = $197.27
Final balance :
Amount held on Monday - Amount withdrawn on Tuesday + Amount deposited on Thursday
$61.72 - $57.00 + $197.27 = $201.99
Hence, final balance = $201.99

The flagpole in front of VHS 50 feet tall. The angle of elevation from the end of its shadow to the top of the flagpole is 46°. what is the length of the shadow? Round your answer to the nearest foot
Answer:
The length of the shadow is 48.28 feet.
Step-by-step explanation:
The flagpole at its shadow form a 46, 44, 90 triangle.
Let AB be the flagpole. AC is the shadow.
Let's use the sine law to calculate AC.
[tex]\frac{AC}{sin(44)}=\frac{50}{sin(46)}\\AC=\sin(44)*\frac{50}{sin(46)}AC=48.28[/tex]

What is the y-intercept of this graph?
A. 0
B. 2
C. 4
D. 8
Answer: 0
Step-by-step explanation:
The line runs through the coordinate (0,0), rather than starting at (0,2), (0,4), or (0,8).
Always remember that you read coordinates as (x,y) which..
X is how many spaces right or left
Y is how many spaces up or down.
Answer:
A. 0
Step-by-step explanation:
If you can look at the graph it crosses the y-axis exactly at the origin which is 0. This makes 0 the y-intercept because the line intercepts the y-axis at the point (0,0) making our solution A: 0

Amanda's parents had a birthday dinner for her at Sushi Yama restaurant. The bill came to $74 before the tip. They left an 18% tip. What was the total cost of Amanda's birthday dinner?
Answer:
$87.32Step-by-step explanation:
Step one:
given data
we are told that the initial bill is $74
thereafter they gave a tip worth 18% of the bill
let us compute what 18% of $74 will amount to
Step two:
=18/100*74
=0.18*74
=$13.32
The added expenses is $13.32
Hence the total cost is
the initial bill plus the tip
=74+13.32
=$87.32

to increase an amount by 19% multiple by?
Answer:
1.19
Step-by-step explanation:
The original full amount is 100%.
When you increase the full amount by 19%, you add 19% of the full amount to the full amount, so now you have 119%.
To find 119% of an amount, multiply he amount by 1.19 since 119% = 1.19
Answer: 1.19

x^(2)+16x+28=0 complete the square
Answer:
(x + 8)² = 36
Step-by-step explanation:
When you are trying to complete the square and the equation already has a constant, you add or subtract that value to the other side of the equation so you can cancel it out.
x² + 16x + 28 = 0
x² + 16x + 28 - 28 = 0 -28
x² + 16x = -28
Now, you find ([tex]\frac{b}{2}[/tex])² (divide b by 2 and raise the quotient to the second power). Half of 16 is 8, and 8² is 64. Add 64 to both sides.
x² + 16x + 64 = -28 + 64
x² + 16x + 64 = 36
Now, you just factor the equation on the left. To factor it, you will always use the number you got to make the constant, which in this case is 8.
(x + 8)² = 36

3/4X - 9 = 27 what does x equal?
Answer:X = 48
Step-by-step explanation:
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
The value of x in the equation given 3x/4 - 9 = 27, is 48.
Given is an equation, 3x/4 - 9 = 27, we need to find the value of x,
To find the value of x, we can solve the given equation step by step. Let's go through the process:
Start with the equation:
3x/4 - 9 = 27
To eliminate the fraction, we can multiply both sides of the equation by 4:
4 × (3x/4 - 9) = 4 × 27
Simplifying, we have:
3x - 36 = 108
Add 36 to both sides of the equation to isolate the variable:
3x - 36 + 36 = 108 + 36
Simplifying further:
3x = 144
Divide both sides of the equation by 3 to solve for x:
(3x) / 3 = 144 / 3
This gives us:
x = 48
Therefore, x equals 48 in the given equation: 3x/4 - 9 = 27.

number of boys and girls are in the class are in the ratio of 7 : 5 the number of boys is 8 more than the number of girls what is a total class strength?
Answer:
Step-by-step explanation:
Given ratio of boys and girls in the class =7:5
No of boys is 8more than the girls
So
Let no of boys in the class =7x
No of girls in the class=5x
7x=5x+8
2x=8
X=8/2
X=4.
Total strength =no of boys + no of girls
=7x+5x
=7×4+5×4
= 28+20
=48.
Total strength in the class is 48.
Answer:
Total class strength = 48
Step-by-step explanation:
Boys : Girls = 7 : 5
Number of boys = 7x
Number of girls = 5x
7x - 5x = 8
2x = 8
x = 8/2
x = 4
Total strength = 7x + 5x = 12x = 12*4 = 48
