Can someone help me pls

Mathematics
1 answer:
Leviafan [203]2 years ago

Answer:

Step-by-step explanation:

0.75 feet / day [ 1 day / 24 hours] * [12 inches / 1 foot]

This process is called dimensional analysis. The trick it uses is to cancel out units (like feet or days ) where possible. In this case, 1 day is going to cancel out and leave behind 24 hours. 1 foot will cancel out and leave behind 12 inches.

It is well worth learning how to do this, because the process is done in the higher sciences.

So what you are left with is

0.75 * 12 inches / 24 hours

0.75 inches /hour * 1/2

0.375 inches / hour.

Write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).
Levart [38]

Answer:

y = 3x - 14

Step-by-step explanation:

Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.

Plug in the slope and given point into y = mx + b, then solve for b:

y = mx + b

4 = 3(6) + b

4 = 18 + b

-14 = b

Plug in the slope and y intercept into y = mx + b

y = 3x - 14

So, the equation of the line is y = 3x - 14

Explain why the graph below does not represent a direct variation
Nitella [24]

Answer:

C. The line does not go through the origin.

Step-by-step explanation:

We have been given a straight line graph that doesn't pass through origin (0,0) and has y-intercept at (0,3).

Now we need to decide why that graph doesn't represent a direct variation.

We know that graph represents variation when it passes through origin. But since given graph doesn't passes through origin so it doesn't represent the direct variation.

Correct choice is :

<u>C. The line does not go through the origin.</u>

Lizards can eat 45 ants per minute. To find how many minutes it takes for lizards to eat 1,080 ants, you have to divide the total amount of ants by how many it can eat per minute.

\frac{1,080}{45}

Divide 1,080 by 45

1,080 \div 45 = 24

It takes lizards <u>24 minutes</u> to eat 1,080 ants

nordsb [41]

Answer:

4.24

Step-by-step explanation:

remember a² + b² = c²

(3*(sqrt(2))² + (3*(sqrt(2))² = 18

this would be c²

square root of this is c = 4.2426...
