Answer:

dr. potter provides 54 vaccinations TOTAL (including both measles and polio).

p+m=54

since there are 4 doses of polio and of measles, you have to use a variable to distinguish how many doses were given for measles and polio out of 142 given doses.

4p+2m=142

p+m=54

4p+2m=142

^^system of equation

p+m=54

4p+2m=142

p=54-m

4p+2m=142

(substitute 54-m to the equation)

4(54-m)+2m=142

m=37

(collect like terms, then substitute the value of m into the first equation)

p=54-37

p=17

(m, p)=(37, 17)

A ball is thrown into the air with an upward velocity of 28ft/s. Its height h in feet after t seconds is given by the function h
Pavlova-9 [17]

Answer:

In bold below.

Step-by-step explanation:

Find derivative which gives the velocity:

V = h' = -32t + 28

At maxm height V = 0 so

-32t + 28 = 0

Time to reach maxm height t = -28/-32 = 0.875 seconds.

So maxm height

= -16(0.875)^2 + 28*0.875 + 8

= 20.25 ft.

Which two whole numbers does the fraction below lie between 31/5
Eddi Din [679]

Answer: 6 and 7

Step-by-step explanation:

For this exercise it is important to remember that Whole numbers Set contains the positive numbers and zero with no fractional part and with no decimal part.

Rational numbers are those numbers that can be written as a fraction, in this form:

\frac{a}{b}

Where "a" is the numerator and "b" is the denominator. Both are integers.

Then, given the following fraction:

\frac{31}{5}

You can express it as a decimal number by dividing the numerator 31 by the denominator 5:

\frac{31}{5}=6.2

Based on the definition of Whole numbers, you can identify that:

6

So the given fraction lies between the following Whole numbers:

6 and 7
