Rachel's biscuits require 0.75 cup of milk for 1 batch. Use dimensional analysis to convert this amount into liters. Use the conversion factors 1 cup/0.5 pints to convert cups into pints, 1 pint/0.5 quart to convert pintos to quarts, and 1 quart/0.94 liter to convert quarts to liters. Use the correct number of significant digits to give your answer

Answers

Answer:

0.75 cup = 0.1763 liters

Step-by-step explanation:

From the question:

Using the conversion factors given in question

We are converting

0.75 cup to liters

Step 1

Convert cups to pint

1 cup = 0.5 pints

0.75 cup = x pints

x = 0.75 × 0.5 pints

x = 0.375 pints

Step 2

Convert pints to Quart

1 pints = 0.5 quart

0.375 pint = x quart

Cross Multiply

x quart = 0.375 × 0.5 quart

x quart = 0.1875 quart

Step 3

Convert from quart

1 quart = 0.94 liter

0.1875 quart = x liter

Cross Multiply

x liter = 0.1875 × 0.94 liter

x liter = 0.17625 liters

Approximately to 4 significant figures= 0.75 cup = 0.1763 liters

Answer:

0.75 cup = 0.1763 liters

James’s little brother and sister wanted to get a face paint. There were 5 kids in front, each kid takes 15 minutes to get their face painted. How many minutes do they have to wait after 3 kids?

Answers

Answer:

9 minutes

Step-by-step explanation:

As it states in the question it takes 15 minutes to paint 5 kids so you do 15/5=3

So it takes 3 minutes to paint each kid.

In the problem it asks how long does it take to paint three kids.

So now we do 3 minutes*3 kids=9 minutes

So it takes 9 minutes to paint three kids

Robert needs to know if the triangle shown is a right triangle. Which equation could he use to help? A. 36+ 25= 49B. 25 + 36 = 49 C. 25 2 + 36 2 = 49 2 D. 36 2 –25 2 = 49 2

Answers

Answer:

C. 25² + 36² = 49²

Step-by-step explanation:

We use the Pythagoras theorem to determine if the triangle is a right angle triangle. The theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In geometry, hypotenuse is the longest side in a right angle triangle. This means it would have the highest number.

A. 36+ 25= 49

This is wrong because the theorem deal with the sum of the squares of the other two sides.

B. 25 + 36 = 49

This is wrong because the theorem deal with the sum of the squares of the other two sides.

C. 25² + 36² = 49²

This is correct as it matches the theorem.

D. 36² –25² = 49²

This is wrong because the theorem deal with the sum of the squares of the other two sides and not their difference.

HURRY PLEASE!!! Which generic rectangle would be used to factor x^2+7x+6

Answers

Answer:

Rectangle B

Step-by-step explanation:

Given the expression x^2+7x+6, to get the required rectangle we need to factorize first;

= x^2+7x+6

= x^2+6x+x+6

= x(x+6)  + 1 (x+6)

= (x+1)(x+6)

From line 2 we will see that the terms contains x², 6x, x and 6. The rectangle that contains all this terms is rectangle B. Hence option B is correct.

Mae Ling earns a weekly salary of $390 plus a 8.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,300 worth of merchandise?

Answers

Answer:

She would make $734 in a work week if she sold $4,300 worth of merchandise.

Step-by-step explanation:

First, you should calculate the amount she would receive on comissions by multiplying the amount she sold for 8%:

$4,300*8%=$344

Now, you have to add the weekly salary plus the amount she receives for the comission on sales:

$390+$344=$734

According to this, the answer is that she would make $734 in a work week if she sold $4,300 worth of merchandise.


HELP, i’m not good a triangles

Answers

Answer:

B

Step-by-step explanation:

SSS stand for Side Side Side, so the truangle must identify all it's sides. To identify sides it uses lines through the side like in B where 1 side has 1 line, 1 side has 2 lines, and the other side has 3 lines. That is the side identifiers, and because each side in B matches with 1 side in A, means that A and B are congruent because they have the same sides, so SSS.
