Answer:

plane: 850 mph
jet stream: 150 mph

Step-by-step explanation:

The speed of the plane is the average of the two speeds. The speed of the jet stream is half their difference.

against: (5600 mi)/(8 h) = 700 mi/h

with: (4000 mi)/(4 h) = 1000 mi/h

Plane's speed = (700 + 1000)/2 mi/h = 850 mi/h

jetstream speed = (1000 -700)/2 mi/h = 150 mi/h

The rate of the jet in still air is 850 mi/h; the rate of the jetstream is 150 mi/h.

The mass of a textbook is approximately 0.00165 metric ton. How is this number written in scientific notation?

Juli2301 [7.4K]

Answer:

B) 1.65 × 10⁻³

Step-by-step explanation:

A number in scientific notation has the form A × 10ⁿ.

A is a number from 1 to 10, but not 10 itself and is called the coefficient.

n is an integer and is called the exponent.

To convert a small decimal number to exponential notation, you move the decimal point to the right until you have one nonzero digit in front of the decimal point.

The exponent is negative of the number of places you moved the decimal point.

To convert 0.001 65 to scientific notation:

Move the decimal point to the right until it is just past the 1. The coefficient is 1.65

Count the number of places you have moved the decimal (three). The exponent is -3.

The number in scientific notation is 1.65 × 10⁻³.

geniusboy [140]

Answer:

6 liters

Step-by-step explanation:

Given:

Renata's recipe for her famous Kale 'n' Clam Quencher calls for kale juice and clam juice in a 3:1 ratio.

If Renata pours 18 liters of fresh kale juice, how many liters of clam juice should she add to maintain this ratio?

Solution:

Ratio to be maintain by using kale juice and clam juice = 3 : 1 ( given)

Renata pours fresh kale juice = 18 liters

We have to calculate quantity of clam juice should be added to maintain this ratio:-

Let quantity of clam juice should be added = $x$

Ratio to be maintain : : quantity of kale juice : quantity of clam juice

$3 : 1=18:x\\ \\ \frac{3}{1} =\frac{18}{x} \\ \\$

By cross multiplication:

$3x=18$

By dividing both sides by 3

$x=6\ liters$

Thus, 6 liters of clam juice should she add.
