In the triangle below, DF = x + 4 and AC = 4x – 6. Solve for x. Type your numerical
answer.

Answer:

foreign stamps = 299

US stamps = 353

Step-by-step explanation:

Let number of foreign stamps be x.

Given she has 54 more U.S stamps than foreign , US stamps = x +54

Total stamps = US + Foreign

652 = x + 54 + x

652 - 54 = 2x

598 = 2x

x = 299

Answer:

The 4th one is the least so you would put that as the first one, then the 2nd one, then the 1st one, then the 3rd one.

Step-by-step explanation:

The fourth one is first because 10 to the power of 0 is 0 times 10 to the power of 1 is still 0 minus 1 to the power of 10 is 1 so 0 minus 1 is -1. The second one is second because 10 to the power of 0 times 10 to the power of 1 is 0, times 1 to the power of 10 is still 0. The first one is third in line because 10 to the power of 0 plus 10 to the power of 1 is 10 times 1 to the power of 10 is 10. The third one is last because its the greatist, 10 to the power of 0 plus 10 to the power of 1 is 10 plus 1 to the power of 10 is 11.

About $48.39

Step-by-step explanation:

Sales tax only applies to the bill, not the tip.

Calculate the sales tax:

38.96 × 8%

38.96 × 0.08

3.1168

Round to the nearest cent:

3.12

Add the sales tax to the bill:

38.96 + 3.12

42.08

Calculate the tip based "on the total amount of the bill:"

42.08 × 15%

42.08 × 0.15

6.312

Round to the nearest cent:

6.31

Add the tip to the rest of the bill:

42.08 + 6.31

Answer:

K = -2J + 24

Step-by-step explanation:

Find two point of the line

(12,0) ; (10,4)

Use this equation:

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y-0)/(4-0) = (x-12)/(10-12)

y/4 = (x-12)/(-2)

y/4 = (-x+12)/2

y = -2x + 24

Answer:

40/41

Step-by-step explanation:

From the given diagram;

BA is the hypotenuse = 41

AC is the opposite = 9

CB is the adjacent = 40

Cos<B = adjaccent/hyp

Cos<B = CB/BA

Cos<B = 40/41

Hence the required ratio is 40/41

Answer:

B.) 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5

Step-by-step explanation:

From the box plot, we can obtain the 5 - Numbe summary and compare with the values in the options given :

Kindly note that each tick mark on the box plot is seperated by a unit of 0.25

Minimum = 0 (starting point of left whisker)

Lower quartile = 0.25 (start point of box)

Median = 0.5 (point in between the box)

Upper quartile = 1.25 (end point of the box)

Maximum = 2.5 (end point of right whisker)

In ascending order we have ;

0, 0.25, 0.5, 1.25, 2.5

The data which best matches the plot is 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5

Answer:

A - 6 units from the y axis. B - 5 units form the x axis. C - 8 units from T to V.

Step-by-step explanation:

So lets go over each question.

A asks for how many units point W is from the y axis. The y axis is the vertical line that goes up and down in the middle of the graph. This line is at x=0.

So we can think of the units between W and the y axis as the distance between W's x coordinates and 0.

In this case, we can see W's x coordinate is at 6.

So this means that W is 6 units from the y axis.

Next we have the distance between the x axis and point U.

The x axis is the line that goes left to right, and is at y=0.

We need to look at the y coordinate of U to find the difference between y=0 and U.

We can see that U is at y=5 on the graph.

So U is 5 units from the x axis.

The last question is the distance between point V and T.

We can see that the x coordinate for both points is x=2.

However, their y coordinates are different.

To find the difference, subtract the y coordinate of one point from the other.

In this case, the y coordinate of V is 5. The y coordinate of T is -3.

So lets see:

v-t=difference of y.

Plug in the values:

5--3

And since the negative sign and the minus sign cancel out:

5+3

=

8

So the difference in y is 8!

Hope this helps!
