jessica increases the temperature of a block of ice by 20º. Which integer represents the amount by which Jessica must change the temperature for the block of ice to return to its starting temperature?

Answer:

h =10

Step-by-step explanation:

3/7 = h/14 -2\7

3/7 = 1/14 h + -2/7

1/14 h + -2/7 = 3/7

1/14 h + -2/7 +2/7 = 3/7 + 2/7

1/14 h = 5/7

14 * ( 1/14h) = 14* (5/7)

h =10

The common factor for the given polynomial is 2x.

A factor is a number that divides another number, leaving no remainder.

Given is a polynomial, 20x³-14x

20x³-14x

= 2x(10x²-7)

Hence, the common factor for the given polynomial is 2x.

Answer:

D

Step-by-step explanation:

y2 is the y to the right, and -6 is to the right of -8 on the x-axis, so (x2, y2) = (-6,52). plug in the values and you get (52-48)/(-6--8), which equals 4/2, which simplifies to 2.

Answer:

D. [tex]y = 2x[/tex]

Step-by-step explanation:

A proportional relationship is represented by the formula [tex]y = mx + b[/tex].

m = the slope, which is  [tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex].

b = the y-intercept, the point where the line crosses the y-axis. We actually don't have to worry about the [tex]+ b[/tex] part of the formula because [tex]b = 0[/tex], so it can be left out.

To find the slope, use [tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex]. Subtract the smaller y value (2) from the larger y value (6).

(6 - 2 = 4)

Then subtract the smaller x value (1) from the larger x value (3).

(3 -  1 = 2)

So it looks something like this now:

[tex]\frac{6-2}{3-1}[/tex] , which equals [tex]\frac{4}{2}[/tex]

Then you divide the top part of the fraction (4) by the bottom part. (2).

[tex]\frac{4}{2}[/tex] = 2. The slope (m) is 2.

So the final equation is [tex]y=2x[/tex].

2) x+y) times 2 + (x*2 times 8)

explanation:

for "times" put a multiplication sign and the astric ( * ) is for the exponent or meaning "to the power of"  :)

The first equation will be formed as:  [tex](5 times 2x) - (3 times 2x)[/tex]

The second equation will be performed as [tex](x + y) times\ 2 + (x*2 \ times 8)[/tex]

When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however other symbols like the "*" sign are also occasionally used.

1.) The composition of 3 and that identical number, multiplied by 5, lowered by the products of 5, and double that amount will be represented as (5 times 2x) - (3 times 2x)

2.) The product of the square root of the first variable and eight times a quantity x and a quantity will be represented as (x+y) times 2 + (x*2 times 8)

Greetings from Brasil

Let us call the distance AB of Y (in the problem nothing is said about this dimension, so lets call of Y).

From the attached drawing we can conclude that:

AB + BC = AC

where

  AB = Y

  BC = 2X + 4

  AC = 24

then

AB + BC = AC

Y + (2X + 4) = 24

-Take [tex]25x[/tex] and divide it on both sides of the equation:

[tex]\frac{-25x}{-25} = \frac{10}{-25}[/tex]

[tex]x = -\frac{2}{5}[/tex]

From the question

r = 7 inches

So the area of the circle is

A = 3.14(7)²

We have the final answer as

Hope this helps you

Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14

We know,

Here,

So, let's find the area,

➝ Area of the circle = πr²

➝ Area of the circle = 3.14 × 7²

➝ Area of the circle = 3.14 × 49

➝ Area of the circle = 153.86 inch²

Answer: 12

Step-by-step explanation:

Let p represent this unknown amount.

Nari pours three-fourths of this volume into an empty pot. This can be written as:= 3/4 × p = 3/4p = 0.75p

She then adds another 2 pints of water and the pot now holds a total of 11pints of water. This means we will add 2 to 0.75p and equate to 11. This will be:

0.75p + 2 = 11

0.75p = 11 - 2

0.75p = 9

p = 9/0.75

p = 12

P equals to 12

This question is based on solving linear equation.Therefore, the answer is 12 pints of total amount of water.

Given:

Nari pours three-fourths of this volume into an empty pot.She then adds another 2 pints of water. The pot now holds a total of 11 pints of water.

Let the unknown amount of pints of water is  p.

According to the question,

She pours three-fourths of this volume into an empty pot. This can be written as:

[tex]\dfrac{3}{4}\times p= \dfrac{3}{4} p = \bold{0.75p}[/tex]

She add on  2 pints of water  to 0.75 p in pot, then it becomes  total of 11 pints of water.

In ,mathematically expressed as,

[tex]\begin{alligned}0.75p+2&=11\\0.75p&=11-2\\0.75p&=9\\p&=\frac{9}{0.75}\\\bold{p&=12}\end{alligned}[/tex]

Therefore, there is total amount of 12 pints water.
