Helene drove 70 km on 4 L of gasoline. Which proportion would help determine how far she can travel on a full 30 L tank of gasol

kondor19780726 [428]

I think it would be 70/4=x/30 because if she went 70km on 4L she could go Xkm on 30L

Find the measure of arc DF (with an explanation of how to solve please!)

allochka39001 [22]

Answer:

mDF = 90°

(Assuming arc mCE is 5x + 10)

Step-by-step explanation:

When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.

So in this case, we have:

70° = (mCE + mDF)/2

Assuming mCE is 5x + 10, we have:

70 = (5x + 10 + 11x + 2)/2

70 = (16x + 12)/2

70 = 8x + 6

8x = 64

x = 8

So the arc mDF is:

mDF = 11x + 2 = 11 * 8 + 2 = 90°

Please find the surface area of the cone (image attached) and reduce answer to nearest tenth, if necessary.

Luba_88 [7]

Answer:

$S.A = 135.6 yd^2$ (

Step-by-step explanation:

Surface area of cone is given as:

Surface Area (S.A) = πr(r + l)

Where,

$r = radius = 3 yd$

$l = slant height = 11.4 yd$

Take π as 3.14

Plug the given values into the formula to find the surface area.

$S.A = 3.14*3(3 + 11.4)$

$S.A = 9.42(14.4)$

$S.A = 135.6 yd^2$ (rounded to the nearest tenth)

Select True or false for each statement

PilotLPTM [1.2K]

Answer:

False

True

False

Step-by-step explanation:

1. We have to get the sum as follows :

$3\frac{4}{9} + 4\frac{6}{9}$

= $\frac{31}{9} + \frac{42}{9}$

= $\frac{31 + 42}{9}$

= $\frac{73}{9}$

= $8\frac{1}{9} \neq 7\frac{1}{9}$

So, this is false.

2. We have to get the sum as follows :

$4\frac{5}{6} + 1\frac{3}{6}$

= $\frac{29}{6} + \frac{9}{6}$

= $\frac{29 + 9}{6}$

= $\frac{38}{6}$

= $6\frac{2}{6}$

So, this is true.

3. We have to get the difference as follows :

$4\frac{5}{8} - 2\frac{4}{8}$

= $\frac{37}{8} - \frac{20}{8}$

= $\frac{37 - 20}{8}$

= $\frac{17}{8}$

= $2\frac{1}{8} \neq 2\frac{3}{8}$

So, this is false.

4. We have to get the difference as follows :

$7\frac{5}{8} - 4\frac{2}{8}$

= $\frac{61}{8} - \frac{34}{8}$

= $\frac{61 - 34}{8}$

= $\frac{27}{8}$

= $3\frac{3}{8} \neq 3$

So, this is also false. (Answer)
