Mike have 103 Baseball cards while Allan have 84 and Michelle jog at 4 mile per hour while Jamie ride bike at 12 mile per hour.

<h3>How to calculate speed?</h3>
  • Speed is determined by the formula: speed = distance × time. To determine the units for speed, you must first know the units for distance and time.
  • Since the distance in this example is measured in metres and the time in seconds, the units will be metres per second (m/s) (s).
  • Or, to put it another way, you can figure out how long it will take by multiplying the distance by the speed. If you know two of the inputs, you can calculate the third one.
  • If a car travels 120 miles in two hours, for instance, we may get the speed as 120 / 2 = 60 miles per hour. Add the speed and the time together to obtain the distance.

Baseball cards Allan have = 84

Baseball cards Mike have = 84 + 19 = 103

Baseball cards Mike have 103

Jamie can ride at 12 mile per hour

Michelle jog at 12 / 3 = 4 mile per hour

wolverine [178]

Answer:

19.5 ounces of spices

Step-by-step explanation:

Raheem made 14 ounces of curry sauce which contained (among other things), 3.25 ounces of spices. He wants to make a larger batch for a family dinner and decides he will need a total of 84 ounces of sauce altogether. How many ounces of spices will he need to complete his recipe?

The question above is calculated as:

14 ounces of sauce = 3.25 ounces of spices

84 ounces of sauce = x ounces of spices

Cross Multiply

14x = 84 × 3.25

x = 84 × 3.25/14

x = 19.5 ounces of spices

Hence, for 84 ounces of curry sauce he would need 19.5 ounces of spices

the value of n is both 5 times as much as the value of m and 36 more than the value of m. what are the values of n and m? explai
Ray Of Light [21]

You said that        n = 5m

AND                     n = m + 36 .

Well then, if those two quantities are both equal to 'n', then
they must be equal to each other, and we can write

                                               5m = m + 36

Subtract 'm' from each side:    4m =       36

Divide each side by 4 :              m =        9 .

OK.  We're half done.

Way back at the beginning, the first thing you told me
was that 'n' is 5 times the value of 'm'. 

                                   n = 5 (m)

Well !  Now we know what 'm' is, so

                                   n = 5 (9) = 45 .

√(4/7)^2 =<br> equations with square roots and cube roots
zhenek [66]

Answer:

See below

Step-by-step explanation:

If you are squaring a number, and then taking the square root of it, you are essentially undoing the original operation:

\displaystyle \sqrt{\biggr(\frac{4}{7}\biggr)^2}=\biggr[\biggr(\frac{4}{7}\biggr)^2\biggr]^{\frac{1}{2}}=\biggr(\frac{4}{7}\biggr)^{2*\frac{1}{2}}=\frac{4}{7}

Hence, we are back starting with the original number
