Sam walked 3/5 of a mile to school. He also walked 6/7 of a mile on his way home. How far did Sam walk in all?

3/5 of 1 mile = 3/5 × 1 = 3 / 5 = 0.6 mile
6/7 of 1 mile = 6/7 × 1 = 6 / 7 = 0.85 mile

total walking distance = 0.6 + 0.85 = 1.45 miles

IF IN FRACTIONS : 3/5 + 6/7
to equalise the denominators multiply 3/5 by 7...........and in 2nd fraction multiply 6/7 by 5

this will become : 21/35 + 30/35
= 51/35 miles

HOPE IT HELPED !!

$\frac{3}{5} + \frac{6}{7}$ you have to get the common denominator which will be:

$\frac{3*7}{5*7} + \frac{6*5}{7*5} = \frac{21}{35} + \frac{30}{35} = \frac{51}{35} or 1 \frac{16}{35} or 1.46$

Hope that helps

Please help me get the right answer?!

The answer is A, $\frac{1}{81}$ . This is because when plugging in -2 for x, the expression will look like this: $9^{-2}$ . To make the exponent positive, you have to flip it into a fraction. Then it will be $\frac{1}{9^2}$ . Lastly, you simplify the denominator into 81.

Answer : The value of x and y is, $90^o$ and $43^oC$

Step-by-step explanation :

First we have to calculate the angle B.

As we know that,

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Thus, $\angle B=\angle C$

Given : $\angle C=47^o$

$\angle B=\angle C=47^o$

$\angle B=47^o$

Now have to calculate the angle A.

As we know that the sum of interior angles of a triangle is equal to $180^o$ .

$\angle A+\angle B+\angle C=180^o$

$\angle A+47^o+47^o=180^o$

$\angle A+94^o=180^o$

$\angle A=180^o-94^o$

$\angle A=86^o$

Now we have to determine the angle y.

As we know that, line AD is an angle bisector. That means, it divides into two equal angles. So,

$\angle y=\frac{\angle A}{2}$

$\angle y=\frac{86^o}{2}$

$\angle y=43^o$

Now we have to determine the angle x.

As we know that the sum of interior angles of a triangle is equal to $180^o$ .

$\angle y+\angle B+\angle x=180^o$

$43^oc+47^o+\angle x=180^o$

$\angle x+90^o=180^o$

$\angle x=180^o-90^o$

$\angle x=90^o$

Thus, the value of x and y is, $90^o$ and $43^oC$

A square root function has both x and y intercepts.

Nata [24]

Step-by-step explanation:

Square Root:

The equation will never touch the x - axis or the y - axis,so the function does not have an x - or y- intercept. ...Therefore,the x- and y- intercepts are 0.

I hope it's helpful!
