Dionte needs to make at least $140 over winter break to pay back his parents. If he makes $15 per sidewalk that he shovels for, how many sidewalks must he shovel to meet his goal?

Answer:

x=1/2,-5/2

Step-by-step explanation:

Answer:

x=82

Step-by-step explanation:

You start of with subtracting both sides with 9

then you divide both side with 9

Remember the rule that whatever you do to one side, you have to do to the other side. So, how do we find x? The objective when we are simplifying equations like this is to isolate x. We need to make x lonely on one side. So let's try!

747 = 9x + 9

What is the first step to making x lonely? Usually try to use the property of addition or subtraction because it makes things 10x easier. So, using the idea of using addition or subtraction, let's make x lonely by minusing 9 on both sides.

747 = 9x + 9

- 9           - 9   (Remember we have to do the same thing to both sides!)

738 = 9x

Now we have 9 times x = 738. Hm, how do we make x lonely even more? What if divide both sides by 9. We are dividing both sides by 9 because this way, the 9 times will cancel out and disappear. Look:

738 = 9x

÷9     ÷9

82 = x

And there we go, we made x completely lonely and found out x = 82!

The mathematical formula  for the area of the triangle is:

base x height / 2

Answer:

7) circumference = 11.78 ft

8) arc NMP = 198° or 27.63 ft

Step-by-step explanation:

7) circumference = πd = (3.14) (3 3/4) = 11.78 ft

8) radius = 8 ft

diameter = 2 x 8 = 16 ft

arc NM + arc QP = 360° - 162° - 162° = 36°

arc NM = arc QP because they are arcs of vertical angles.

arc QP = 18°

arc NMQ = 180°

arc NMP = 180° + 18° = 198°

circumference = πd = (3.14)(16) = 50.24 ft

(198°/360°)(50.24) = 27.63 ft

Given:

The equation of the curve is:

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

To find:

The gradient of the given curve at the point where [tex]x = 4[/tex].

Solution:

We have,

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

Differentiate with respect to x.

[tex]y'=\dfrac{5}{2}x^{\frac{5}{2}-1}[/tex]       [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]

[tex]y'=\dfrac{5}{2}x^{\frac{3}{2}}[/tex]

Substituting [tex]x=4[/tex], we get

[tex]y'=\dfrac{5}{2}(4)^{\frac{3}{2}}[/tex]

[tex]y'=\dfrac{5}{2}(2^2)^{\frac{3}{2}}[/tex]

Using properties of exponents, we get

[tex]y'=\dfrac{5}{2}(2)^{2\times \frac{3}{2}}[/tex]         [tex][\because (a^m)^n=a^{mn}][/tex]

[tex]y'=\dfrac{5}{2}(2)^{3}[/tex]

[tex]y'=\dfrac{5}{2}(8)[/tex]

[tex]y'=20[/tex]

Therefore, the gradient of the given curve at the point where [tex]x = 4[/tex] is 20.

16) 16x+2+43x+1 = 180 59 x = 177 x = 3

17) 29x+3+31x-3 = 180 60x = 180 x = 3

18) 16x -5 + -5 + 22x = 180 38x = 190 x = 5

Answer:

It's exactly the same, except the size

Step-by-step explanation:

Answer:

They are similar because if you look at the length of 2 of the sides that you know

Triangle ABC has side length 1 and 2 or 1:2

CFE has sides length 2 and 4 or 2:4 and 2:4 can also be written as [tex]\frac{2}{4}[/tex] which is a fraction, and fractions can be simplified to 1:2.

So they are similar but just one is bigger then the other.

Answer:

Home by $17.50

Step-by-step explanation:

Home by 17.50 because when going to the theater you have to consider all the costs of everything you will be purchasing so there will be 2 tickets for yourself and your friend 2 drinks and 2 small popcorns when you add all of these up it will look like this 7.75+7.75+2.50+2.50+2.50+2.50 = 25.50 then I will subtract this from the at home cost so 25.50 - 4.50 - 1.50 - 2.00 = 17.50 So it's cheaper home by 17.50

Answer:

Jacob sold 25 bars - chocolates and 15 peanut butter.

Step-by-step explanation:

Jacob sold 40 candy bars.

Let the bars - chocolate be x and peanut butter be y and made $65.

Now,

x + y = 40 ...(1)

2x + y = 65 ...(2)

Now, From equation (1) we get,

x + y = 40

x = 40 - y

Now, put the value of x = 40 - y in equation (2) we get,

2x + y = 65

2(40 - y) + y = 65

80 - 2y + y = 65

y = 80 - 65

y = 15

Now, put the value of y in equation (1)

x + y = 40

x + 15 = 40

x = 40 - 15

x = 25

The bars - chocolate = x = 25 and

peanut butter = y = 15

Thus, Jacob sold 25 bars - chocolates and 15 peanut butter.

Answer:

Same y-intercept

Step-by-step explanation:

They have the same y-intercept of 2

look a y intercept is where the function crosses the y axis or when x is 0

In the chart y=2 when x =2 meaning a y intercept of 2

in the graph u can see the line going through the y intercept at (0,2)

So they have the same y-intercept

Answer:

x = .06418

Step-by-step explanation:

2 + (9.2)−8x = 2.32

(9.2)−8x = 2.32 − 2

log (9.2)−8x = log .32

−8x log 9.2 = log .32

−8x log 9.2

−8 log 9.2

=

log .32

−8 log 9.2

x = .06418
