figure 1 has a volume of 250 cubic meters. Figure 2 has a volume of 128 cubic meters. If figure 2 has a height of 12 meters, the
LUCKY_DIMON [66]

Answer:

15 m.

Step-by-step explanation:

If the figures are similar then the ratio of their heights is

∛128 / ∛250

= 0.8.

So 0.8 = 12/ h      where h is the height of figure 1,

h = 12 / 0.8

= 15 m.

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.
Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is x.

180 = 44 + 90 + x

180 = 134 + x

x= 46

The angle y of the other triangle plus the angle x of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

90 = x + y

90 = 46 + y

y=44

To find ?, we have

180 = 58 + 44 +?

180 = 58 + 44 +?

? =78

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

180 = x + 50 + 25\\180 = x+ 75\\x=105

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

180 = 36 + 105 + y

180 = 141+ y

y=39

?=39

A direct variation function contains the points (-8,-6) and (12, 9). Which equation represents the function?
mrs_skeptik [129]

Answer:

y=\dfrac{3}{4}x.

Step-by-step explanation:

The direct variation is defined as

y\propto x

y=kx

where, k is constant of proportionality.

It is given that a direct variation function contains the points (-8,-6) and (12, 9).

Substitute x=-8 and y=-6 in the above equation.

-6=-8k

Divide both sides by -8.

\dfrac{-6}{-8}=k

\dfrac{3}{4}=k

The value of constant of proportionality is \dfrac{3}{4}. So, the required equation is

y=\dfrac{3}{4}x

At x=12,

y=\dfrac{3}{4}(12)=9

It means, the line passing through (12,9). Hence, the equation is correct.

Therefore, the equation of the function is y=\dfrac{3}{4}x.

Find the result when 30 is decreased by 85%. ...?
Naddika [18.5K]
We can first change 85% in the decimal form:
85 % = 0.85
30 x 0.85 = 25.5
30 - 25.5 = 4.5
Or we can do it another way :
30 x ( 1 - 0.85 ) = 30 x 0.15 = 4.5
