darlene uses 4 nails for every 12 inches of wood how many nails will she use in 6 feet of wood

Answer: The rate represents a decrease in speed for each 1% grade increases.

Step-by-step explanation:

You can use the fact that normal slope is measurement of how much the height changes as we walk on the ground for a unit distance forward. And that percent calculates everything compared to 100 parts.

The rate of change or slope, in this situation tells that if we walk 100 units horizontally, then the slope percent gives us the amount of height increased compared to height before walking 100 units.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Suppose that we have to measure the rate of change of y as x changes, then we have:

[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

where we have

[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]

Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.

(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)

(where dependent variable is height and the independent variable is the distance walked horizontally)

Slope percent  = [tex]Slope \times 100[/tex] = [tex]\dfrac{y_2 - y_1}{x_2 - x_1} \times 100[/tex]

This, shows that, if we walk 100 units horizontally, then the slope percent gives us the amount of height increased.

Answer:

m∠QPR = 35°         m∠QPM =40°       m∠PRS = 30°

Step-by-step explanation:

ΔPRQ is a right triangle with right angle at R.  So m∠QPR = 90 - 55 = 35

ΔQPM is a right triangle with right angle at M.  So m∠QPM = 90 - 40 = 40

Arc RQ = 2(35) = 70 and arc SR = 2(25) = 50.  

So arc PS = 180 - (arc RQ + arc SR) = 180 - (70 + 50) = 180 - 120 = 60

Now arc PS is the intercepted arc for ∠PRS.  

Therefore, m∠PRS = 60/2 = 30

I used the fact that an inscribed angle has a measure 1/2 the measure of the intercepted arc several times.  Also, I used the fact that the acute angles of a right triangle are complementary.  And, finally I used the fact that an inscribed angle in a semicircle is a right angle.

Answer: 48 feet below the surface

Step-by-step explanation:

From the question, we are informed that two divers are underwater. Nick is 33 feet below the surface while Tristan is 15 feet above him.

Tristan's depth will be represented as x.

Therefore, x - 33 = 15

x = 15 + 33

x = 48

Therefore, the answer is 48 feet below the surface.

Answer:

B 18 feet below

Step-by-step explanation:

So subtract 33-15 bechas depth means below and since tristan has less of a depth to go rather than Nick you would subtrac.

Answer:

4.5

Step-by-step explanation:

1+2=3

3/4+3/4=6/4=1.5

3+1.5=4.5

Eloise ran a total of 9/2 miles, which can also be expressed as 4.5 miles.

To find out the total number of miles Eloise ran, we need to add the distances she ran on Monday and Tuesday.

On Monday, Eloise ran [tex]1\frac{3}{4}[/tex] miles.

On Tuesday, she ran [tex]2\frac{3}{4}[/tex] miles.

To add these distances, we need to find a common denominator for the fractions.

The least common multiple of 4 and 4 is 4.

Converting the mixed numbers to improper fractions:

[tex]1\frac{3}{4} = \frac{(1 \times 4 + 3)}{4}[/tex]

[tex]= \frac{7}{4}[/tex]

[tex]2\frac{3}{4} = \frac{(2 \times 4 + 3)}{4}[/tex]

[tex]= \frac{11}{4}[/tex]

Now, we can add the fractions:

7/4 + 11/4

= 18/4

Simplifying the fraction:

18/4

= 9/2

Therefore, Eloise ran a total of 9/2 miles, which can also be expressed as 4.5 miles.

Answer:

y = 2.5x + 3

Step-by-step explanation:

y = mx + b

y = 2.5x + 3

As you can see, each unit is not 1, its 0.5. We need to go up 5 times, and so 0.5 times 5 gives us 2.5, and thats how i got my slope.

I got 3 as my y-intercept because it's were the line intersects the y axis.

Answer:

y=5x+3

Step-by-step explanation:

Slope: y2-y1 over x2-x1 so it will be 3-(-2) over 0-(-1) and the answer will be 5.

Y intercept: In order to find the y intercept it is necessary to replace the y an x coordinate in the equation: y= mx+b and replace 3=5(0)+b... simplifying would be 3=b

so the final answer would be y=5x+3

Answer:

Step-by-step explanation:

First, look at your terms. You have two terms and two variables in each. So they can be factored out because you can distribute them back in easily.

Focus one variable first, x. You cant factor an x^12 out of an x^4. You can, but you really don't want to, it'll turn your problem into a mess. So the only thing you can do is factor out the lower exponent, x^4.

[tex]x^4(x^8y^4-y^1^2)[/tex]

We arent done yet because the terms still share the y variable. You cant factor a y^12 from a y^4. This is the same problem with the x variable. So take out the lower one, y^4.

Step-by-step explanation:

115+x = 135 (remote interior angles)

x = 135-115

x = 20

Please Make Me Brainlist

Answer:

20

Step-by-step explanation:

first look at the line which says a and 135, they add up to 180 so

a + 135 =180

a= 180-135

a= 45

Then to find the x we will have to add all the angles inside the triangle which would add up to 180

So,

x+115+45=180

x+160=180

x=180-160

x=20

THEREFORE X = 20⁰

Answer: -5/4

Step-by-step explanation:

Answer:

= -5/4

Step-by-step explanation:

To find the slope, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -9 - -4)/( -4 - -8)

   = ( -9 +4)/( -4 +8)

    = -5/4

Answer:

The correct answer is 1.75

Step-by-step explanation:

5 x 0.50 = 2.5

3 x 1.25 = 3.75

2 x 2.75 = 5.5

Then we want to add

2.5 + 3.75 + 5.5 = 11.75

Now, Subtract.

11.75 - 10.00 = 1.75

The total amount spent will be equal to $12, so the money added by Ralph will be equal to $2.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data given in the question,

The total money Ralph has is $10.

Price of each pencil = $0.50

Then, price of 5 pencil will be = 5 × 0.50 = $2.5

Price of each pen = $1.25

Then, the price of 3 pens will be = 3 × 1.25 = 3.75

Price of each notebook = $2.75

Then, the price of 2 notebooks will be = 2 × 2.75 = 5.5

Then, the total money spent by Ralph = 5.5 + 3.75 + 2.75 = 12

The money that he should have to add will be,

$12 - $10 = $2
