Answer:

1/8

Step-by-step explanation:

Substitute a = 3/8 into the equation.

$(3*\frac{3}{8} - \frac{3}{4} ) * \frac{1}{3} = (\frac{9}{8} - \frac{6}{8}) * \frac{1}{3}$

$=\frac{3}{8} * \frac{1}{3} = \frac{1}{8}$

Solve the following proportion. х 42 35 10

anzhelika [568]

Answer:

Step-by-step explanation:

The proportion is equal to $\frac{x}{10}=\frac{42}{35}$

We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

$60=5x$

Dividing both sides by 5, we have the answer as

$x=12$

A car that normally sells for $20,000 is on sale for $16,000. What percent of the original price of the car is the final price?

Travka [436]

Answer:

80%

Step-by-step explanation:

20000. take out 3 zeros from both numbers and you get 20 and 16. 20 is 4 times 5 and 16 is 4 times 4 if 20 is 100% then 4 over 5 is 80%

PLEASE HELP!!! Write the equation of a line that goes through the point (6, 3) and is perpendicular to the line y = 4x + 1.

Tpy6a [65]

For this case we have that by definition, the equation of a line in the point-slope form is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It is the slope of the line and $(x_ {0}, y_ {0})$ is a point through which the line passes.

We have the following equation of the slope-intersection form:

$y = 4x + 1$

Where the slope is $m = 4$

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope:

$m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4}\\m_ {2} = - \frac {1} {4}$

Thus, the equation will be of the form:

$y-y_ {0} = - \frac {1} {4} (x-x_ {0})$

Finally we substitute the given point and we have:

$y-3 = - \frac {1} {4} (x-6)$

What is the m= And what is the equation Please help me asap its almost due

Alenkasestr [34]

Answer:

m = 1 $\frac{1}{7}$ , y = 1 $\frac{1}{7}$ x + 10

Step-by-step explanation:

The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)

m = $\frac{rise}{run}$

= $\frac{2-10}{7-0}$

= $\frac{8}{7}$

= 1 $\frac{1}{7}$

Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1 $\frac{1}{7}$ x + 10.

Find the measure of the numbered angles in rhombus ABCD

sasho [114]

Answer:

see the explanation

Step-by-step explanation:

we know that

In a Rhombus opposite angles are congruent and consecutive angles are supplementary

The diagonals are perpendicular and bisect the angles

step 1

Find the measure of angle 4

we know that

$m\angle 4=27^o$ --->by the diagonals bisect the angles

step 2

Find the measure of angle 1

we know that

$m\angle 1=27^o$ ----> by opposite angles are congruent

step 3

Find the measure of angle 2

we know that

$m\angle 1=m\angle 2$ ----> by the diagonals bisect the angles

$m\angle 2=27^o$

step 4

Find the measure of angle 3

we know that

$m\angle 3=90^o$ ----> by the diagonals are perpendicular

step 5

Find the measure of angle 5

we know that

$m\angle 5+27^o=90^o$ ----> by complementary angles

$m\angle 5=90^o-27^o=63^o$

step 6

Find the measure of angle 6

we know that

$m\angle 6=m\angle 5$ ----> by the diagonals bisect the angles

$m\angle 6=63^o$
