About how many loaves of bread equal the weight of 1 gallon of water? use a strip diagram to write an equations

1 answer:

3 0

I saw the image.
Bread = 1 pound
1 fluid once of water weight about 1 ounce.

1 liquid gallon = 127.998 ounce or 128 ounces
1 pound = 16 ounces

128 ounces ÷ 16 ounces/pound = 8 pounds

Since 1 loaf of bread weighs 1 pound and 8 pounds is equal to 1 liquid gallon of water then, 8 loaves of bread equals the weight of 1 gallon of water.

Use the distance formula to find the distance between (1 3) and (-2 9) rounded to the nearest hundredth

frosja888 [35]

Answer:

D = 6.71

Step-by-step explanation:

The distance formula is $D = \sqrt {(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2} }$

Decide which point will be Point 1 and Point 2.

Point 1: ( 1,3 ) x₁ = 1 y₁ = 3

Point 2: (-2, 9) x₂ = -2 y₂ = 9

Substitute the information into the formula.

$D = \sqrt {(x_{2} -x_{1})^{2} +(y_{2} -y_{1})^{2} }$

$D = \sqrt {(-2 -1)^{2} +(9 -3)^{2} }$ Simplify within the brackets

$D = \sqrt {(-3)^{2} +(6)^{2} }$ Square each number

$D = \sqrt {9 +36 }$ Add

$D = \sqrt {45 }$ Exact answer as a radical (root number)

$D = 6.708....$ Answer in decimals

$D = 6.71$ Rounded answer to nearest hundredth

The nearest hundredth is the second place value. It rounds up because the value after it is "8", which is greater than 4.

For what value of constant c is the function k(x) continuous at x = 0 if k =

nlexa [21]

The value of constant c for which the function k(x) is continuous is zero.

<h3>What is the limit of a function?</h3>

The limit of a function at a point k in its field is the value that the function approaches as its parameter approaches k.

To determine the value of constant c for which the function of k(x) is continuous, we take the limit of the parameter as follows:

$\mathbf{ \lim_{x \to 0^-} k(x) = \lim_{x \to 0^+} k(x) = 0 }$

$\mathbf{\implies \lim_{x \to 0 } \ \ \dfrac{sec \ x - 1}{x}= c }$

Provided that:

$\mathbf{\implies \lim_{x \to 0 } \ \ \dfrac{sec \ x - 1}{x}= \dfrac{0}{0} \ (form) }$

Using l'Hospital's rule:

$\mathbf{\implies \lim_{x \to 0} \ \ \dfrac{\dfrac{d}{dx}(sec \ x - 1)}{\dfrac{d}{dx}(x)}= \lim_{x \to 0} sec \ x \ tan \ x = 0}$

Therefore:

$\mathbf{\implies \lim_{x \to 0 } \ \ \dfrac{sec \ x - 1}{x}=0 }$

Hence; c = 0

andrezito [222]

Answer:

Answer is 1/2 or .5.

Step-by-step explanation:

Out of a die, numbers 2, 4, and 6 are even. So 3/6 numbers on a dice are even. Reduced, the answer is 1/2.

netineya [11]

Answer:I believe it's 31,771

Step-by-step explanation: you first need to add 8,999 + 2,387 to get 11,386 then add 11,386 + 11,386 to get 22,772 and then add 8,999 to get 31,771.
