9. The temperature of a liquid that is increasing can be represented by the equation
f(t) = 64 + 4t, where t is the time in hours. Graph the function to show the temperatures over the
first 10 hours. Use the graph to estimate the temperature after 7 hours.
Answers
Answer:
92°F
Step-by-step explanation:
in degrees Fahrenheit,
t=7
f(7)=64 + 4(7)
=92
The required temperature of liquid after 7 hours is 92.
Given that,
The temperature of a liquid that is increasing can be represented by the equation f(t) = 64 + 4t, where t is the time in hours. Graph the function to show the temperatures over the first 10 hours. To use the graph to estimate the temperature after 7 hours.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
f(t) = 64 + 4t
T = 7
f(7) = 64 + 4 * 7
= 64 + 28
= 92
Thus, the required temperature of liquid after 7 hours is 92.

Janice bought an antique clock originally priced at $967 but on sale for 5% off. After 1% sales tax, what was the total cost?
Answers
Answer:
927.84
Step-by-step explanation:
The total cost of the antique clock that Janice bought is $927.82 approximately.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, we have:
Original price of clock = $967Sale discount = 5% on original price1% sales tax on the discounted priceTotal cost = (discounted price of clock)'s price + sales tax of discounted price.
Let d = discounted price of the clock
Then, we have:
[tex]d = $967 - \text{5\% discount on 967} \\\\d = 967 - \dfrac{967}{100} \times 5 = \$918.65[/tex]
1% sales tax on 'd' will be: [tex]\dfrac{d}{100} \times 1 = \$9.1865 \approx \$9.19[/tex]
Thus, we get:
Total cost of the clock ≈ 918.65 + 9.19 = 927.82 (in dollars)
Thus, the total cost of the antique clock that Janice bought is $927.82 approximately.

The relation between the sides and angles of a right triangle is the basis for trigonometry.
Step-by-step explanation:
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).
Answer:
The legs
Step-by-step explanation:
In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

Choose an equivalent system of equations to the following system:
Fx + Gy = H
Qx + Ry = S
6Fx + Gy = 6H
Qx + 6Ry = S
6Fx + 6Gy = 6H
Qx + Ry = S
Fx + 6Gy = 6H
Qx + Ry = S
6Fx + 6Gy = 6H
Qx − Ry = S
Answers
Answer:
B. 6Fx + 6Gy = 6H
Qx + Ry = S
Step-by-step explanation:
Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.
_____
Comments on other choices
A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.
B: the correct choice
C: see A.
D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.

The sum of two numbers is 147. The difference of the two numbers is 25.
What are the two numbers? Show your work.
Answers
x + y = 147
x - y = 25
I always found second setting that second equation up was hardest. How do I know which one comes first? You just keep them in the same order as the first math equation.
So let’s solve for x in terms of y:
x - y = 25
x = 25 + y
Then substitute that into your first equation:
x + y = 147
(25 + y) + y = 147
2y = 122
y = 61
x = 25 + y = 25 + 61 = 86
