Answer:
575
Step-by-step explanation:
First, divide 2 7/8 by 1/4. This gives you 11.5. Then, multiply 50 by 11.5, giving you 575.
The number of miles represented by [tex]2\frac{7}{8}[/tex] inches is 575 miles.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, 1/4 inch on a map represents 50 miles.
So, 1 inch is represented by
= 50÷1/4
= 50×4
= 200 miles
The number of miles represented by [tex]2\frac{7}{8}[/tex] =23/8 inches
23/8 ×200
= 23×25
= 575 miles
Therefore, the number of miles represented by [tex]2\frac{7}{8}[/tex] inches is 575 miles.

What is the quotient of 6/7 and 3/14
Answer:
6/7 divided by 3/14=4
Step-by-step explanation:
Hope this helps!
Answer: 4
Step-by-step explanation: To divide fractions, you have to switch the operation to multiplication, and multiply the first fraction by the reciprocal of the second fraction. So 6/7 times 14/3. Cross cancel out, so 14 and 7. 7 cancels out to be 1, 14 cancels out to be two. 6 and 3, are the same thing. So in the end you have 2/1 times 2/1 which is 4.
Last month, Sheldon earned $12.80 in interest on a $320 deposit into his bank account. If the interest earned is directly proportional to the amount deposited, how much interest can Sheldon expect next month if he deposits $830?
Answer:
[tex]x=\$ 32.20[/tex]
Step-by-step explanation:
[tex]\frac{12.80}{320}=\frac{x}{830} \therefore 320x=830\times12.80[/tex]
[tex]x=\$ 32.20[/tex]
Answer:
the answer is $487.20 if he expects to deposits $830

Exponential Decay Function
The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.
The equation of the model is:
[tex]M(t)=M_o\cdot(1-r)^t[/tex]
[tex]M(t)=970\cdot(1-0.277)^t[/tex]
Operating:
[tex]M(t)=970\cdot 0.723^t[/tex]
After t=13 minutes the remaining mass is:
[tex]M(13)=970\cdot 0.723^{13}[/tex]
Calculating:
M(13)=14.3 gram

What is the image of ( 3 , − 5 ) (3,−5) after a dilation by a scale factor of 5 5 centered at the origin?
Answer:
The coordinates of the image will be: (15, -25)
Step-by-step explanation:
Given the point
(3,−5)The scale factor 5.A scale factor of 5 means that the new shape is five times the size of the original.
The coordinates of the image of (3,−5) after dilation by a scale factor of 5 centered at the origin can be obtained by multiplying the original coordinates of the object point by 5.
i.e.
(x, y) → (5x, 5y)
(3, -5) → (5×3, 5×(-5)) = (15, -25)
Therefore, the coordinates of the image will be: (15, -25)

Answer:
-9/22t
Step-by-step explanation:
since the denominators (22) and the variable are the same, you can pretend as if you are only solving -4 - 5
-4 minus 5 is making the number go farther left from the zero on the number line
so the number itself is getting bigger, but the sign will stay negative
if you move five left from -4 on a number line you get -9
so now you can add the denominator to your answer: -9/22 t
