Step-by-step explanation:
A baker puts a chocolate cake in the oven to bake for 30 minutes. Let f(t) = 0.25 + 65 be the temperature of the cake t minutes
after you placed it in the oven. Which of the following statements are true for the given function?
LET ME KNOW ASAP
Answer:
Options (1) and (5)
Step-by-step explanation:
Given function 'f' representing the relation between temperature of the oven after 't' minutes is,
f(t) = 0.25t² + 65
Option (1).
f(0) means that when the cake was placed in the oven, its temperature was 65°.
True.
f(0) = 0 + 65 = 65
Option (2).
To find the temperature after 15 minutes, we need to find 't' when f(t) = 15
False.
We have to find the value of f(15) to find the temperature of the oven after 15 minutes.
Option (3).
Temperature of the cake was 81° F when it was kept in the oven for 8 minutes.
Given statement is False.
It should be represented by,
f(8) = 81
Option (4).
After 10 minutes,the temperature of the cake was 71.25 degree F.
False.
By putting t = 10 in the function,
f(10) = 0.25(10)² + 65
= 25 + 65
= 90° F
Option (5).
The temperature of the cake when the baker takes it out of the oven, can be represented by,
f(30) = 290
True.
f(30) = 0.25(30)² + 65
= 225 + 65
= 290
Tom and Joe are racing towards each other in a game of "chicken." Each boy is riding in a plastic canoe. They are at the local YMCA pool and are starting at a distance of 100 feet apart. Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second. How long will it take for the boys to meet?
Answer:
50 seconds
Step-by-step explanation:
We are told in the question that the distance between them = 100ft
Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second.
The formula for Distance = Speed × Time.
Hence, the Algebraic equation is given as:
6ft/s × t = 4ft/s × t + 100
6t = 4t + 100
6t - 4t = 100
2t = 100
t = 100/2
t = 50 seconds
It will take 50 seconds for the boys to meet.
What is the slope of the line y= 7x + 19 (5)
A line's slope or gradient, which is expressed as a number, indicates the line's steepness and X and Y directions.
The slope of the line y = 7x + 19 (5) exists 7.
What is meant by the slope of the line?The units of the slope (dy/dx), which correspond to speed or velocity, in this case are km/m.y since the y axis is measured in kilometres and the x axis in millions of years. Both the slope and the y intercept might have a positive or negative value. Slope is defined as the y-axis divided by the x-axis.
The slope expresses how quickly the dependent variable changes when the independent variable changes. The Greek capital letter D or D is frequently used by mathematicians and economics to represent change. Slope contrasts the change in the vertical axis, y, with the change in the horizontal axis, x.
A line's slope or gradient, which is expressed as a number, indicates the line's steepness and X and Y directions.

If PQR measures 75°, what is the measure of SQR?
22°
45°
53°
97°
Answer:
The Answer is 53
Step-by-step explanation:
if angle PQR is 75 and PQS is 22... 75-22 is 53
The measure of the angles SQR if PQR measures 75° is 53 degrees
What is Angle?An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.
We have,
<PQR = 75 degrees
<PQS = 22 degrees
From the given diagram
<PQR = <PQS + <SQR
Substitute the given values into the formula
75 = 22 + <SQR
<SQR = 75 - 22
<SQR = 53 degrees
Hence, the measure of the angles SQR is 53 degrees

Chardai reads 25% of a book each night that has 280 pages. How many pages will she read
each night?
HINT: twenty-five percent OF 280
Answer:
70 pages
Step-by-step explanation:
Remember that in math, "of" usually means we multiply.
Here, Chardai reads 25% OF a 280-page book each night.
So, we multiply 25% by 280:
25% * 280 = (25/100) * 280 = (1/4) * 280 = 70
The answer is 70 pages.

Teresa makes 9 dollars for each hour of work. Write an equation to represent her total pay p after working h hours
Answer:
P=9h
Step-by-step explanation:
Since Teresa makes 9 dollars for each hour of work, we can say:
9 dollars/1 hour.
Her total pay will be on one side of the equation:
p=
Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:
h hours
Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.
p=9h

The probability that an event will happen is P(E)=0.34. Find the probability that the event will not happen.
Please I need urgent help
The probability of certainty is 100%=1
If Probability(p)=0.34
then
Probability (p) +cProbability (!p) = 1 where !p is used to denote "not "p

Probability(!p)=1−0.34=0.66
The probability that the event will not happen is 0.66.
What is the probability of an event?The probability of an event can be defined as the chance of happening that particular event.
The probability that the event will happen is P(E) = 0.34.
Therefore, the probability that the event will not happen is

4 2/3 ÷7
Answer:
2/3
Step-by-step explanation:
Convert the mixed fraction into an improper one:
4 2/3 = 4*3 + 2 / 3 = 14 / 3.
Then divide:
14/3 ÷ 7 = 14÷7 / 3 = 2 / 3
Answer:
14/21
Step-by-step explanation:
First, we turn 4 2/3 into an improper fraction. We do this by multiplying 4 by 3 and then adding 2 to this product.
4×3 = 12
12 + 2 = 14
Now, our equation is simplified to 14/3 ÷ 7. Now, all we can do is divide 14/3 by 7.
14/3 ÷ 7 = 14/21
So, our evaluated and simplified answer is 14/21.

Step-by-step explanation:
[tex]4=0\cdot \:x-14[/tex]
[tex]Switch\:sides[/tex]
[tex]0\cdot \:x-14=4[/tex]
[tex]\mathrm{Apply\:rule}\:0\cdot \:a=0[/tex]

[tex]\mathrm{Subtract\:the\:numbers:}\:0-14=-14[/tex]
[tex]-14=4[/tex]
[tex]The\:sides\:are\:not\:equal[/tex]
[tex]No\: Solution[/tex]
x is infinity which means it has no solutions.
Given,
4 = ax - 14
We need to solve for x.
We have,
4 = ax - 14
Now,
We have to assume a = 0.
we get,
4 + 14 = ax
ax = 4 + 14
x = (4+14) / a
x = 18 / a
So,
Putting a = 0 in x = 18 / a
We get,
x = 18/0 = ∞
We can say that x has no solutions.
Thus x is infinity which means it has no solutions.
