The answer is 3/7

Step-by-step explanation:

Find the GCD of both 35 and 15. This is 5.

Then, divide the numerator and denominator by the GCD.

15 ÷ 5/ 35 ÷ 5

This equals 3/7.

HELP ME PLEASE

Arada [10]

Answer:

if you toss a dice 30 times, you will roll a two 5 times.

Step-by-step explanation:

If you toss a dice once, the probability of rolling a 2 is 1/6, like you said.

So if you multiply your chances of rolling a 2 by 30, you get;

30.1/6 = 30/6 = 5

Find the slope of the lines. Are the 2 lines parallel or perpendicular? Explain how you can use the slope of two lines to tell i

rewona [7]

Answer:

slope = $\frac{3}{7}$ and - $\frac{7}{3}$ , perpendicular

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = $\frac{3}{7}$ x + 11 is in this form with m = $\frac{3}{7}$

Rearrange 7x + 3y = 13 into this form

subtract 7x from both sides

3y = - 7x + 13 ( divide all terms by 3 )

y = - $\frac{7}{3}$ x + $\frac{13}{3}$ ← in slope- intercept form

with m = - $\frac{7}{3}$

• Parallel lines have equal slopes

• The product of perpendicular slopes = - 1

The lines are not parallel since slopes are not equal

$\frac{3}{7}$ × - $\frac{7}{3}$ = - 1

Hence lines are perpendicular

What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning

stellarik [79]

Answer:

8 grams

Step-by-step explanation:

The balance is in equilibrium, so the weights of the two sides are equal.

Let the weight of a square be s.

Left side: 2s + 4

Right side: s + 3(4) = s + 12

The weights are equal, so we set the two expressions equal.

2s + 4 = s + 12

s = 8

Answer: The weight of a square is 8 grams.
