if
[tex] \frac{f}{g} = \frac{1}{4} [/tex]
and
[tex] \frac{g}{h } = \frac{2}{5} [/tex]
what is the ratio of f:h​

Answers

Answer 1

Answer:

f:h = 1 : 10

Step-by-step explanation:

[tex]\frac{f}{g}=\frac{1}{4}\\\\Cross multiply,\\\\4f = g\\\\g = 4f ------------(I)\\\\\frac{g}{h}=\frac{2}{5}\\\\\frac{4f}{h}=\frac{2}{5} from(I)\\\\\frac{f}{h}=\frac{2}{5*4}\\\\\frac{f}{h}=\frac{1}{5*2}\\\\\frac{f}{h}=\frac{1}{10}[/tex]

The radius, r, of the base is 16 cm. The height, h, is 25 cm. What is the length of the slant height, l, in centimeters?

Answers

Answer:

Step-by-step explanation:

What shape? A right cone?

√(16^2+25^2) =√881 ≈ 29.7cm

The length of the slant height is 29.68 centimeters.

What is Pythagoras theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

The radius, r, of the base is 16 cm.

The height, h, is 25 cm.

To find the length of slant height:

Using the Pythagorean theorem,

l = √(25)² + (16)²

l = 29.68 centimeters.

Therefore, slant height is 29.68 centimeters.

Find the ten missing angles labeled in the diagram. Line a is parallel to line b. The measures of two angles are given.​

Answers

Answer:

m∠3 = 112°     m∠5 = 38°     m∠6 = 68°    m∠8 = 74°

You do the others

Step-by-step explanation:

Facts you need to solve this problem.

1.  Vertical angles are congruent

2.  Alternate interior angles are congruent when lines are parallel

3.  Sum of the measures of the angles of a triangle is 180

4.  Adjacent angles are supplementary when two lines intersect

m∠3 = 112°   (Reason 1 above)

m∠6 = 180 - 112 = 68°   (Reason 4)

m∠6 + m∠5 + 74 = 180°  (Reason 3)

68 + m∠5 + 74 = 180

142 + m∠5 = 180

m∠5 = 38°

m∠8 = 74°  (Reason 2)

That gives you a start, so I will let you find all the others.  OK?  I know you don't want to do that, but you need to be able to do this type of problem.  Now, go for it!!

Brenda had 3/4 of a pizza. Her sister ate 1/2 of her pizza. How
much pizza did Brenda's sister eat?

Answers

her sister are two slices of pizza,

you multiply 1/2 to make it equivalent to 3/4 so once you multiply it should turn out to be 2/4 which means her sister ate 2 slices,lmk if 2 was an option.

1/8? If brenda at 3/4. Then theres 1/4 left. Her sister ate 1/2. So 1/4 divided in half would be 2/8. So i think its 1/8. Im not sure but you can try.
