18 questions answered correctly on a test. that is 75% of the total number of questions. How many questions were on the test?
adelina 88 [10]

Answer:

24 = questions on test

Step-by-step explanation:

Questions answered correctly = questions on test * percent answered correctly


We know that she answered 18 correctly and that 75% were answered correctly

Substitute this information into the equation

18 = questions on test *.75

Divide by .75 on each side

18/.75 = questions on test *.75/.75

24 = questions on test

Answer:

Its 9.0 units

Step-by-step explanation:

For the side mostly to the left, its gonna be 3 units, since we can easlily count it

Now, for the diagonals, we have to use the formula for the area of a triangle, which is (l * w) / 2 = a.

For the bottom side, its 3 along the x axis and 1 along the y axis. 3 * 1 is 3, now divide that by 2 and you got 1.5

Now, for the right side, its 5 on the y, 1 on the x. Multiply 1 by 5, you got 5. Now divide that by 2 and you have 2.5

Finally, for the top side, its 4 on the x, and 1 on the y. 4 * 1 is 4, divided by 2 and its 2.

Alright, now we have to add 'em all together. 3 + 1.5 + 2.5 + 2 is 9 units

Theres your answer :)

Common difference refers to how you get from one value in the sequence to the next.

Becky has been tracking the population of a town. The population was 5,340 last year and has been increasing by 1.75 times each
Scorpion4ik [409]
<span> the population grows at rate of 1.75
multiply it by this rate every year
As in year 3 it would be 5340(1.75)(1.75)(1.75) the function is 5340(1.75)^x
</span>f(x) = 5340(1.75)^x where 1.75 is the rate of growth 
so D is right answer
