8 ones 9 hundredths - 3.4

1 answer:

5 0

8 ones = 1 X 8 = 8
0 tenths = 0 X 1/10 = 0
9 hundredths = 9 X 1/100 = 0.09.

Now we can add everything together to obtain the value.

8 + 0 + 0.09 = 8.09.

Now we can find the difference between the 2 values.

8.09 - 3.40 = 4.69.

4.69 is the final answer.

Which best explains whether or not all isosceles triangles are similar?

The third statement is correct.

All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.

Answer:

4.71 minutes

Step-by-step explanation:

Incomplete question [See comment for complete question]

Given

Shape: Cone

$r = 3$ -- radius

$h = 7$ --- height

$Rate = 14in^3/min$

Required

Time to pass out all liquid

First, calculate the volume of the cone.

This is calculated as:

$V = \frac{1}{3} \pi r^2h$

This gives:

$V = \frac{1}{3} * 3.14 * 3^2 * 7$

$V = \frac{1}{3} * 197.82$

$V = 65.94in^3$

To calculate the time, we make use of the following rate formula.

$Rate = \frac{Volume}{Time}$

Make Time the subject

$Time= \frac{Volume}{Rate }$

This gives:

$Time= \frac{65.94in^3}{14in^3/min}$

$Time= \frac{65.94in^3}{14in^3}min$

Cancel out the units

$Time= \frac{65.94}{14} min$

$Time= 4.71 min\\$

Polygon R and polygon S are similar. The perimeter of polygon R is 136 cm, and the perimeter of polygon S is 64 cm. If one side

e-lub [12.9K]

Answer

Option A) 17cm

Explanation

Polygon R and polygon S are similar. This means the polygon R and S have equal number of sides.

Step 1 : Find the number of sides of polygon S

The perimeter of polygon S is 64 cm. If one side of polygon S is 8 cm

Therefore, Number of sides of polygon S = 64/8 = 8 sides

and number of sides of polygon R = 8 side

Step 2 : Find the number of sides of polygon R

The perimeter of polygon R is 136 cm,

Number of sides of polygon R = 136/8 = 17 cm

Therefore side length of polygon R = 17 cm

Perhaps that Margos spends X dollars on her paycheck , then I found my equation . 0.25 X + 0.125X + 24 = 60 ( 1/8 is equal to 0.125 ). After u solved this equation u will get $96 for the total amount of her paycheck.
