Answer:

$\huge\boxed{42.9 \%}$

Step-by-step explanation:

=> $\frac{3}{7}$

To make it a percentage, we need to multiply and divide it by 100

=> $\frac{3}{7} * \frac{100}{100}$

=> $\frac{300}{700}$

To make the denominator 100, we'll divide the numerator and denominator by 7

=> $\frac{300/7}{700/7}$

=> $\frac{42.9}{100}$

Percentage means out of hundred, so it becomes

=> 42.9 %

koban [17]

<h2>Answer:</h2><h2>Bethany started het homework at 3.05 PM approx 3 PM.</h2>

Step-by-step explanation:

The number of problems completed by Bethany = 25

The time taken to complete 1 problem = 3 minutes

The time taken to complete 25 problems = 25 * 3 = 75 minutes

Bethany finished her math homework at 4:20 p.M.

So she started 75 minutes 4.20 PM, (i.e) 3.05 PM or

approx around 3 PM.

Anettt [7]

Answer:

The statement is True!

Step-by-step explanation:

Clare paid full price for an item.

Let Price of the item = x

Han bought the same item for 80% of the full price.

Han bought it for 0.8x

Clare said, I cants believe I paid 125% of what you paid, Han!

The above statement is True if;

125% of 0.8x = x

1.25 * 0.8x = x

x =x

The statement is True!

The distance from the centroid of a triangle to its vertices are 16cm, 17cm, and 18cm. What is the length of the shortest median

Marizza181 [45]

Answer:

$24$ $\text{cm}$

Step-by-step explanation:

Given: The distance from the centroid of a triangle to its vertices are $16\text{cm}$ , $17\text{cm}$ , and $18\text{cm}$ .

To Find: Length of shortest median.

Solution:

Consider the figure attached

A centroid is an intersection point of medians of a triangle.

Also,

A centroid divides a median in a ratio of 2:1.

Let G be the centroid, and vertices are A,B and C.

length of $\text{AG}$ $=16\text{cm}$

length of $\text{BG}$ $=17\text{cm}$

length of $\text{CG}$ $=18\text{cm}$

as centrod divides median in ratio of $2:1$

length of $\text{AD}$ $=\frac{3}{2}\text{AG}$

$=\frac{3}{2}\times16$

$=24\text{cm}$

length of $\text{BE}$ $=\frac{3}{2}\text{BG}$

$=\frac{3}{2}\times17$

$=\frac{51}{2}\text{cm}$

length of $\text{CF}$ $=\frac{3}{2}\text{CG}$

$=\frac{3}{2}\times18$

$=27\text{cm}$

Hence the shortest median is $\text{AD}$ of length $24\text{cm}$

An equation of the line that contains the origin and the point (1,2) is

Semmy [17]

(0,0)(1,2)......(0,0) is the origin
slope = (2-0) / (1-0) = 2/1 or just 2

y = mx + b
slope(m) = 2
(1,2)...x = 1 and y = 2
now we sub, we r looking for b, the y intercept
2 = 2(1) + b
2 = 2 + b
2 - 2 = b
0 = b

ur equation is : y = 2x + 0...or just y = 2x
