Answer:
Step-by-step explanation:
Let m and n represent the numbers. Then m + n = 97 and n - m = 7.
Solving the second equation for n, we get n = m + 7. Substituting m + 7 for n in the first equation we obtain:
m + (m + 7) = 97, or
2m + 7 = 97, or 2m = 90
Dividing both sides by 2, we get m = 45. Then n must be 52.

Find the number if 12% of it is 10% of 6
Answer:
0.072
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
"Find the number if 12% of IT is 10% of 6."
"It" means "the number," and we can represent this number as "x."
So,
12% * x = 10% * 6
3/25x=3/5
x=5
So, the number is 5.

Enter the equation of the circle described below.
Center (5,2), radius = 3
Answer:
[tex](x-5)^2+(y-2)^2=9\\[/tex]
Step-by-step explanation:
So, you basically want the equation of the circle.
Given:
Center(C): [tex]C(5, 2)[/tex]
[tex]r=3[/tex]
The equation of circle is:
[tex](x-h)^2+(y-k)^2=r^2\\[/tex]
Where, [tex](h, k)[/tex] represents the center point and [tex]r[/tex] is the radius of the circle.
Plotting the values in the equation:
[tex](x-5)^2+(y-2)^2=3^2\\[/tex]
[tex](x-5)^2+(y-2)^2=9\\[/tex]
This is the equation of the circle of center (5, 2) and radius 3.

Step-by-step explanation:
The volume of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A = [tex]\frac{1}{2}[/tex] bh( b is the base and h the height ), thus
A = [tex]\frac{1}{2}[/tex] × 14 × 18 = 7 × 18 = 126 in²

In one day, a yoga instructor teaches 3 classes in the morning and 4 classes in the afternoon. The length of each class is m minutes.
Which expression represents the total number of minutes the yoga instructor teaches in one day?
OA 7m
OB 7+ m
ОС. 10
D10 + m
Answer:
B. 7m
Step-by-step explanation:
She has 7 classes a day (3+4), and each takes the same number of minutes. If m stands for minutes per class, you can find the total minutes per day by multiplying 7 by m. Therefore the answer is 7m.
Example: Let's say a class takes 30 minutes, you would put 30 in the place of m, 7x30=210, so she would be teaching 210 minutes of yoga class each day.

Which graph shows y= (-5x) -4?
Answer: Your answer is A. Hope this helps!
Answer:
A
Step-by-step explanation:
carbon monoxide is a gas that is 43% carbon. carbon dioxide only 27% carbon. suppose that the environmental protection agency (epa) analyzes exhaust from cars, a mixture of carbon monoxide and carbon dioxide. if the epa finds that a 1600 mg sample of exhaust gas has 32% carbon, how many mg of the sample were carbon monoxide, and how many were carbon dioxide?
Answer:
500 mg Carbon Monoxide
1100 mg Carbon Dioxide
Step-by-step explanation:
Weight of total sample = 1600 mg
Percentage of Carbon in Carbon Monoxide = 43%
Percentage of Carbon in Carbon Dioxide = 27%
Percentage of carbon in Mixture = 32%
Let amount of Carbon Monoxide = [tex]x[/tex] mg
Amount of Carbon Dioxide in mixture = (1600-[tex]x[/tex]) mg
Amount of carbon in [tex]x[/tex] mg of Carbon Monoxide =
[tex]x \times 43\%\\\Rightarrow x \times \frac{43}{100} ...... (1)[/tex]
Amount of carbon in (1600-[tex]x[/tex]) mg of Carbon Monoxide =
[tex](1600-x) \times 27\%\\\Rightarrow (1600-x) \times \frac{27}{100}......(2)[/tex]
We know that the sample of 1600 mg contains carbon because of Carbon Monoxide and Carbon Dioxide present in it.
Adding (1) and (2) and equating to 32% of 1600 mg:
[tex]x \times \dfrac{43}{100} + (1600-x) \times \dfrac{27}{100} = 1600 \times \dfrac{32}{100}\\\Rightarrow x \times (43-27) = 1600 \times (32-27)\\\Rightarrow 16x = 1600 \times 5\\\Rightarrow x =500[/tex]
Amount of Carbon Monoxide in sample,[tex]x[/tex] = 500 mg
Amount of Carbon Dioxide in sample = (1600 - [tex]x[/tex]) = (1600 - 500) = 1100 mg
Hence, answer is
500 mg Carbon Monoxide
1100 mg Carbon Dioxide

The answer is the top one to the right
The graph that represents the function g(x) = 2(0.5)ˣ -1 is given.
What is graph?In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.
The relationships between two or more items are frequently represented by the points on a graph.
Given expression,

What is the domain of the function Y= In(x+ 2)?
x <-2
XX-2
x <2
X> 2
Answer:
x > -2
Step-by-step explanation:
Domain is the range is of all possible value for x in y= f(x) .
Domain of logarithmic function log(x) is given by x > 0.
It means any value can greater than x can be plugged in place of x in function log(x).
In the given function Y= In(x+ 2). In place of x there x+2 .
Thus x+2> 0
subtracting -2 from both sides
=> x+2 -2> 0-2
=> x > -2
Thus, domain of the function Y= In(x+ 2) is x > -2
