Ms. Swanson asked the question, "How does knowing the fact 6 × 5 6×5 help you find 60 × 500 60×500?" Maria answered, "I know 6 ×

Allushta [10]

Answer:

Correct answer is 30,000

Step-by-step explanation:

From multiplication :

6 * 5 = 30

Now moving to:

60 * 500

Number of ending zeros in both values = 3 ; (000)

This 3 0's will be placed at the end of the result of multiplying 6 by 5

Hence,

6 * 5 = 30

60 * 500 = 30+000 = 30,000

Hence, 60 * 500 = 30000

50 POINTS!!!!!! AND BRAINLIEST!!! PLEASE HELP. SAT.

QveST [7]

Answer:

2b -a

a-2c

Step-by-step explanation:

a = b+c

We want to find b-c

Solve the first equation for b

b = a-c

and for c

c = a-b

b-c in terms of b and a

using c = a-b

b - (a-b)

Distribute the minus sign

b - a +b

Combine like terms

2b -a

b-c in terms of c and a

using b = a-c

(a-c) -c

a-c -c

Combine like terms

a-2c

rodikova [14]

Given:

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2).

To find:

The intersection point of medians DG and EH.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

$Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)$

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2). So, the centroid of the triangle is

$Centroid=\left(\dfrac{0+2+(-4)}{3},\dfrac{5+0+2}{3}\right)$

$Centroid=\left(\dfrac{-2}{3},\dfrac{7}{3}\right)$

$Centroid=\left(-0.666...,2.333\right)$

Round each coordinate to the nearest tenth.

$Centroid=\left(-0.7,2.3\right)$

Therefore, the correct option is C.
