Solve in logarithms no scam 94100×√38.2\5.68^3×8.14 pls help don't scam pls

maks197457 [2]

Answer:

389.89879489

Step-by-step explanation:

1. Multiply

(5.68^3 × 8.14= 1491.65851648)

94100 × √38.2 / 1491.65851648

2. evaluate root

(√38.2 = 6.18061485)

94100 × 6.18061485 / 1491.65851648

3. multiply 

(94100 × 6.18061485 = 581595.85796324)

581595.85796324 / 1491.65851648

4. divide

(581595.85796324 / 1491.65851648 = 389.89879489)

Determine whether line AB and line CD are parallel, perpendicular, or neither. A( 4, 2), B(-3, 1), C(6, 0), D(-10, 8)

Lapatulllka [165]

Answer:

<h2>neither</h2>

Step-by-step explanation:

If AB an CD are parallel, then their slopes are the same.

If AB and CD are perpendicular, then the product of their slopes is equal -1.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Calculate the both slope:

$A(4,\ 2),\ B(-3,\ 1)\\\\m_{AB}=\dfrac{1-2}{-3-4}=\dfrac{-1}{-7}=\dfrac{1}{7}\\\\C(6,\ 0),\ D(-10,\ 8)\\\\m_{CD}=\dfrac{8-0}{-10-6}=\dfrac{8}{-16}=-\dfrac{1}{2}\\\\=============================$

$m_{AB}\neq m_{CD}$

The line AB and line CD are not parallel

$m_{AB}\cdot m_{CD}=\left(\dfrac{1}{7}\right)\left(-\dfrac{1}{2}\right)=-\dfrac{1}{14}\neq-1$

The line AB and line CD are not perpendicular.

Jing is helping the kindergarten teacher put together bags of crayons. Each bag has 4 crayons, and 1/4 of the crayons in each ba

wariber [46]

Answer:

A) $\frac{3}{12}$

Step-by-step explanation:

Given:

Jing is helping the kindergarten teacher put together bags of crayons.

Each bag has 4 crayons, and 1/4 of the crayons in each bag are green.

What fraction of the crayons in 3 bags are green?

Solution:

1 bag contains number of crayons = 4

1 bag contains number of green crayons = $\frac{1}{4} \ of\ 4 = \frac{1}{4}\times4=1$

Total number of bags = 3

Total number of crayons in 3 bags = 4 $\times$ 3 = 12

1 bag contains number of green crayons = 1

Total number of green crayons in 3 bags = 1 $\times$ 3 = 3

Fraction of the green crayons out of total = 3 out of 12 = $\frac{3}{12}$

Therefore, fraction of the crayons in 3 bags are green are $\frac{3}{12}$

Y = -x + 5 y = 2x - 7

Pavlova-9 [17]

Answer: x=4, y=1

Step-by-step explanation:

Because y=y, you can make an equation that is -x+5=2x-7. Then add the x to the right side, so it would be 5=3x-7. Then add the 7 to the left side to get all of the numbers in one place. So it would be 12=3x. Divide by 3 on both sides and you get x=4. Then plug x into either one of the original equations. Both equations should get you the same answer for y. Y=-4+5. Y=1. And the other equation. Y=2x-7, y=8-7. Y=1
