Answer:

1:2

Step-by-step explanation:

First, find how many are green

Add up the number of blue and red ones:

10 + 15 = 25

Subtract this from 50

50 - 25 = 25

So, 25 are green.

Since there are 50 marbles in total, the ratio will be 25:50

This can be simplified, since both numbers are divisible by 25.

So, the ratio is 1:2

If an altitude is drawn from the right angle of a right triangle to its hypotenuse, the two segments formed on the hypotenuse ar
valentina_108 [34]

Answer:

the length of the altitude is 7.5 cm

Step-by-step explanation:

In a Δ ABC, \overline {BC} is the altitude

If an altitude is drawn to the hypotenuse of the right angle triangle as shown in the image attached below; Then:

(AD)^2 = AD*AC \\ \\ x^2 = 5*11.25 \\ \\ x^2 = 81.25 \\ \\ x = \sqrt{81.25} \\ \\ x= 9.01

NOW;

(BC)^2 = DC*AC \\ \\ z^2 = 11.25 *16.25 \\ \\z^2 = 182.8125 \\ \\ z= \sqrt{182.8125} \\ \\  z= 13.52

Finally; the altitude which is \overline {BD} is calculated as:

(BD)^2 = AD*DC \\ \\ y^2 = 5*11.25 \\ \\ y^2 = 56.25 \\ \\ y = \sqrt{56.25} \\ \\ y= 7.5

Thus; the length of the altitude is 7.5 cm

What is the volume of a rectangular prism with the dimensions: base 3 1 2 cm, height 1 1 2 cm, and length 5 1 2 cm?
jenyasd209 [6]

Answer:

The volume of a rectangular prism is 28\frac{7}{8}\ cm^{3}

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

V=BHL

Convert the given dimensions to an improper fractions

B=3\frac{1}{2}\ cm=\frac{3*2+1}{2}=\frac{7}{2}\ cm

H=1\frac{1}{2}\ cm=\frac{1*2+1}{2}=\frac{3}{2}\ cm

L=5\frac{1}{2}\ cm=\frac{5*2+1}{2}=\frac{11}{2}\ cm

substitute in the formula

V=(\frac{7}{2})(\frac{3}{2})(\frac{11}{2})=\frac{231}{8}\ cm^{3}

Convert to mixed number

\frac{231}{8}=\frac{224}{8}+\frac{7}{8}=28\frac{7}{8}\ cm^{3}
