Solution for 17=w-4 equation:

17=w-4

We simplify the equation to the form, which is simple to understand

17=w-4

We move all terms containing w to the left and all other terms to the right.

-1w=-4-17

We simplify the left and right sides of the equation.

-1w=-21

We divide both sides of the equation by -01 to get w.

w=21

Answer:

The answer is A

Step-by-step explanation:

step 1. if r = 2, then its area = (pi)r^2 = (pi)(4) = 4pi

step 2. if r = 3 then its area = (pi)r^2 = (pi)(9) = 9pi

step 3. so A is the area of a circle half the sum of our circles with r = 2 and r = 3.

step 4. A = (4pi + 9pi)/2 = 13pi/2 =6.5(pi).

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.

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.

Hope this helped!

Have a supercalifragilisticexpialidocious day!

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:

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.

I hope this helped.

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

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:

CD = [tex]\sqrt{164}[/tex]

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = C(5, - 2) and (x₂, y₂ ) = (D(- 3, 8)

d = [tex]\sqrt{(-3-5)^2+(8+2)^2}[/tex]

   = [tex]\sqrt{(-8)^2+10^2}[/tex]

    = [tex]\sqrt{64+100}[/tex]

    = [tex]\sqrt{164}[/tex]

     = 2[tex]\sqrt{41}[/tex] ← in simplest form

As, we have C (5, - 2) and D (- 3, 8), to find CD let's use distance formula :

[tex] \underline{\boxed{\tt{Distance \: between \: two \: points = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}}}}[/tex]

Here,

So, by filling values :

[tex] \sf : \implies CD = \sqrt{(-3 - 5)^{2} + (8 - (-2))^{2}}[/tex]

[tex] \sf : \implies CD = \sqrt{(-8)^{2} + (8 +2))^{2}}[/tex]

[tex] \sf : \implies CD = \sqrt{64 + (10)^{2}}[/tex]

[tex] \sf : \implies CD = \sqrt{64 + 100}[/tex]

[tex] \sf : \implies CD = \sqrt{164}[/tex]

Hence, distance of CD is [tex] \bold{\sf \sqrt{164}.}[/tex]

You can use the given function to evaluate the expected sales at year 2009 and 2015 and use the net difference divided by time as the average rate of change.

The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941

Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:

[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

where when

[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]

Since the sales is given by the function [tex]g(t) = t^3 - 2t^2 + 4t - 7[/tex], and the inputs are 2009 and 2015, thus, evaluating g(t) (sales) at those values of t, we get:

[tex]g(2009) = 8023737057[/tex] (replaced 2009 with t and calculated)

[tex]g(2015) = 8096096703[/tex] (replaced 2015 with t and calculated)

Using these values to calculate the average rate

[tex]\text{average rate} = \dfrac{g(2015) - g(2009)}{2015 - 2009} = \dfrac{72359646}{6} = 12059941\\[/tex]

Thus,

The average rate of change in expected sales from 2009 to 2015 is given by $12,059,941
