Step-by-step explanation:

V = B×H ⇒ H = V ÷ B

H = 729 ÷ 108 = 6.75 inches

Answer:

h = 6.75 inches

Step-by-step explanation:

The volume (V) of a prism is calculated as

V = Ah ( A is the area of the base and h the height )

here V = 729 and A = 108 , then

108h = 729 ( divide both sides by 108 )

h = 6.75 inches

Answer:

[tex]\frac{16}{225}[/tex]

Step-by-step explanation:

When attempting probability problems we want to figure out the chances of something happening. This turns into something like:

[tex]\frac{\text{marble drawn}}{\text{total marbles}}[/tex]

In this case we have 8 red marbles, 2 green marbles, and 5 blue marbles in a bag. That brings us to a total of 15 marble.

Since we want to first draw a red marble the chance of that happening would be:

[tex]\frac{8\text{(the marble drawn)}}{15\text{(total # of marbles)}}[/tex]
Now we replace the marble as stated in the problem so we then draw the next marble, which is green.

[tex]\frac{2\text{(the marble drawn)}}{15\text{(total number of marbles)}}[/tex]

All that's left is to multipy the values we got:

[tex]\frac{8}{15} *\frac{2}{15}=\frac{16}{225}[/tex]

That's our answer.

Answer:

slope in parallel = 2

slope in perpendicular = [tex]\sf \bold{-\frac{1}{2} }[/tex]

y intercept = (0, 2)

Rewrite in slope intercept form:

slope intercept form: y = mx + b  || where "m" is slope and "b" is y-intercept

y-intercept:  2  --- as "b" is [+2] then x will be always 0 at y-intercept

slope is same when parallel

perpendicular slope is negative reciprocal of the parallel slope

Convert to slope intercept form

Slope:-

Parallel lines have equal slope

Slope of the perpendicular line=-1/2

[tex]\sf \implies y=242.2\:ft\:(nearest\:tenth)[/tex]

Answer:

A = C = 115°

B = 65°

D = E = 45°

Step-by-step explanation:

65° + C = 180° or 65° + A = 180°, They are supplementary angles that are linear pair that add up to 180°.

A = C = 115°

B° = 65° Vertical Angles meaning they are equal to each other.

D and E are equal to cheat other since the lines on the sides mean that are isosceles.

D + E + 90° = 180°

D + E = 90°

2x = 90

x = 45°

D = E = 45°

The one possible solution can be yy = 10 and xx = 5 .

Inequality refers to the phenomenon of unequal and/or unjust distribution of resources and opportunities among members of a given society. The term inequality may mean different things to different people and in different contexts.

According to the question

Julia and her children went into a restaurant where ,

hamburgers (xx)= $7 each

tacos (yy) = $2.50 each.

Julia has $60 to spend and must buy a minimum of 14 hamburgers and tacos altogether.

i.e,    xx + yy ≥ 14  ----------------------------(1)

       7xx + 2.5yy ≤ 60 ----------------------(2)

from equation (1) and (2)  graph attached ...

solving both equation

multiplying equation (1) with -7

-7xx + -7yy ≤ -98 ----------------(3)

now adding equation (3) and (2)

-7xx + -7yy ≤ -98

7xx + 2.5yy ≤ 60

=   - 4.5yy ≤ -38

=    4.5yy ≥38

=     yy ≥ 8.4

now ,

yy        xx

9         5.35

10         5

11          4.64

Hence, one possible solution can be yy = 10 and xx = 5

[tex]C(A) = 2\times\pi\times OA[/tex]

we know that the circumference of circle B is 3 times the circumference of circle A,

[tex]C(B) = 3\times C(A)[/tex]

The first step for factoring is 3w(x + y) - 4z(x + y). The correct option is (A).

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given algebraic expression is as below,

3wx + 3wy - 4zx - 4zy

In order to factorize it find the common factors for the group terms such that one of the factors is common for both the groups as follows,

3wx + 3wy - 4zx - 4zy

Take (3wx + 3wy) and (- 4zx - 4zy) as two groups.

The factor form for  (3wx + 3wy) is 3w(x + y).

And, for (- 4zx - 4zy) it is -4z(x + y).

Thus, the given expression can be written as,

3wx + 3wy - 4zx - 4zy

= 3w(x + y) - 4z(x + y)

Hence, first step when factoring the given expression is 3w(x + y) - 4z(x + y).

Answer:

Step-by-step explanation:

The values of angles are written below,

a° = 121°

b° = 53°

c° = 87°

d° = 72°

The Inscribed Angle Theorem: This theorem states that the measure of an inscribed angle in a circle is equal to half the measure of the intercepted arc.

In other words, if an angle is formed by two intersecting chords in a circle, the measure of the angle is equal to half the sum of the measures of the arcs intercepted by the angle.

The values of angles are calculated as,

a = (2 x 108 ) - 9 5

a = 121°

b = 360 - ( 121 + 95 + 91 )

b = 53°

c = (121 + 53 ) / 2

c = 87°

d = ( 91 + 53 ) /2

d = 72°

Therefore, the values are a = 121°, b = 53°, c = 87°, and d = 72°.

we know the trapezoids are similar, so that means all sides are at a ratio, thus

that means from the model to actual, the scale is 1:12, so the large side is 12 times as large.

so for the large trapezoid

EF = 6 * 12 =... 72

EH = 4 * 12 =.. 48

HG = 3 * 12 = ..36

GF = 3 * 12 =...36

72+48+36+36 = 192.

Step-by-step explanation:

The freight train was traveling at 40 mph.

Let's use the formula for distance:

distance = rate x time

We know that the two trains are moving away from each other, so we can add their distances to get the total distance between them:

distance = distance traveled by passenger train + distance traveled by freight train

Since they started at the same time, the time traveled by both trains is the same, so we can write:

distance = 80 mph x time + rate of freight train x time

Using the given information, we can write:

720 = 80 x 6 + rate of freight train x 6

Simplifying:

720 = 480 + 6(rate of freight train)

240 = 6(rate of freight train)

rate of freight train = 40 mph
