A square has one side that is 19 cm long. What is the perimeter of the square?

2 answers:

6 0

Since a square has 4 equal sides, just do 19 + 19 + 19 + 19 which is 76. Or, 19 x 4, even though you add with permieter, it'll still work on a square.

Hope I helped!

Square has 4 equal sides and the peremeter is adding all the sides together and so 19 + 19 + 19 + 19 = 76

What is 3/4÷1/2??????

sergiy2304 [10]

Answer:

3/2

Step-by-step explanation:

to divide fractions you just have to multiply them by the reciprocal.

so, instead of 3/4 divided by 1/2

it's changed to 3/4 * 2/1

then you just multiply the numerators together and the denominators together

3*2/4*1

6/4

3/2

3/2

Goodluck with your schoolwork/homework.

Which expression is NOT equivalent to this

Dimas [21]

Answer:

A. 88y -40

Step-by-step explanation:

B is definitely equivalent to 11y-5 because it is reversed so it is the same if it is reversed. and D is equivalent too because 11 divided by 5 equals 2.2 same thing as 22 in this case. and C im not that sure about but i do not think that that is not equivalent...and A. is the answer is NOT equivalent because how the heck do u get 88y-40???????? the answer that is not equivalent is A. 88y-40

Hope this explained well :)

When fritz drives to work his trip takes 40 minutes, but when he takes the train it takes 30 minutes. find the distance fritz t

sweet-ann [11.9K]

Distance = rate*time

convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs

Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.

We know the time we know the speed, Next
distance that Fritz drive = $\frac{2}{3}s$
distance the train travel = $\frac{1}{2}(s+15)$

The question: Assume that the train travels the same distance as the car
==> $\frac{2}{3}s = \frac{1}{2}(s+15)$
==> $\frac{2}{3}s = \frac{1}{2}s + \frac{15}{2}$
==> $\frac{2}{3}s - \frac{1}{2}s = \frac{15}{2}$
==> $\frac{1}{6}s = \frac{15}{2}$
==> $\frac{6}{1} * \frac{1}{6}s = \frac{15}{2} * \frac{6}{1}$
==> $s = 45$
Now we know that Fritz drive at 45 mph,
distance = $\frac{2}{3} * 45 = 30 miles$
