4. On the way to the movies, you get pulled over for speeding. The ticket costs $120 plus $20 for every mph above the speed limit you were driving. If your ticket costs $280, how many mph above the speed limit were you driving? *
20x+280=120
120-20x=280
120x+20=280
120+20x=280

Answer:

Approximate maximum height is 5 ft

[tex]h(\frac{18}{32} )= 5 \ ft[/tex]

Step-by-step explanation:

[tex]h(t)=-16t^{2} + 18t[/tex]      ---------- (1)

Differentiate equation (1)  w.r.t t and equate it to zero (in order to determine maxima)

[tex]h^{'}(t) = -32t+18[/tex]

[tex]0= -32t+18[/tex]

[tex]t=\frac{18}{32}[/tex]

Substitute this value in equation (1)

[tex]h(\frac{18}{32} )=-16(\frac{18}{32} )^{2} + 18(\frac{18}{32} )[/tex]

[tex]h(\frac{18}{32} )=-5+ 10[/tex]

[tex]h(\frac{18}{32} )= 5 \ ft[/tex]

Answer:

The coordinates of the point 3/5 of the way from A(-4,-4) to B(6,6) are (2, 2).

Step-by-step explanation:

Given the points

We need to find the coordinates of the point 3/5 of the way from A(-4,-4) to B(6,6).

Let P be the required point, then

AP : AB = 3 : 5

as

so

AP / AB = 3/5

AP / (AP + BP) = 3/5

5AP = 3(AP + BP)

5AP = 3AP + 3BP

2AP = 3BP

AP/BP = 3/2

AP : BP = 3 : 2

The formula of the coordinates of a point that divides the line joining the points (a, b) and (c, d) in the ratio m : n is:

[tex]\left(\frac{mc+na}{m+n},\:\frac{md+nb}{m+n}\right)[/tex]

For the given division,

m : n = 3 : 2

Thus, the coordinates of the point P are:

[tex]\left(\frac{3\left(6\right)+2\left(-4\right)}{3+2},\:\frac{3\left(6\right)+2\left(-4\right)}{3+2}\right)[/tex]

[tex]=\left(\frac{18-8}{5},\:\frac{18-8}{5}\right)[/tex]

[tex]=\left(\frac{10}{5},\:\frac{10}{5}\right)[/tex]

[tex]=\left(2,\:2\right)[/tex]

Therefore, the coordinates of the point 3/5 of the way from A(-4,-4) to B(6,6) are (2, 2).

Answer:

3 2/3 square feet.

Step-by-step explanation:

You just need to multiply 6 and 4 2/3. To do this you have to change both of them into improper fractions so 6 would be 21/3 and 4 2/3 would be 14/3. If you cross cancel the 21/3 will become 7/3 and the 14/3 will become 14/1. Now you have to multiply across and you should get 98/3. To change the improper fraction into a mixed number you have to divide 98 and 3 so you can get 3 2/3. Therefore, the answer to the area of the quilt is 3 2/3 square feet.

Step-by-step explanation:

Answer:

x=t-p

Step-by-step explanation:

just move p to the other side and since it crosses the equals sign so you have to change it from positive to negative

Answer:

x=t-p

Step-by-step explanation:

To make x the subject of the formula, you’d have to take p to the other side. And when (+p) crosses over to the other side, it changes to (-p) because of the equality sign.

hehehehe is it right??

First, subtract 0.6 from both sides of the numbers and then simplify

Then multiply all terms by the same value to eliminate fraction denominators which gives us 2.8

So, n = 2.8

The area of the garden is increased by 20 % . If the width remains the same, then the new length of the garden is 2.4 yards.

The area of Rectangle is length times of width.

Given that A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide

Area = Length × Width

Area=6 yards.

The area of the garden is increased by 20 % .

20/100=0.2

the area would equal 6 (l x w) and 6 increased by 20% equals 7.2.

As the width remains same

so we use 7.2/3 to find the new length

7.2/3=2.4 yards.

Hence, 2.4 yards is the new length of the garden.

Answer:

x=1

Step-by-step explanation:

Its x=1 because if we put the 1 as in x then it will be like 2(1)+3(4(1)-3)= 8-3(1)

2(1)+3(4(1)-3) is equal to 5

8-3(1) is equal to 5

5=5

so x is 1

Answer:

Because we know the height of the mailbox is 4 feet and the length is 6 feet, and we also know that it's located 54 feet from the base of the flagpole, we can use proportions to solve the problem.

[tex]\frac{4}{6\\}[/tex]=  [tex]\frac{x}{54}[/tex]  

Cross-multiply 4 with 54 and 6 with x to result with 216=6x. Divide 6 to both sides to get 36. So, the height of the flagpole would be 36 feet.

Answer: 3r + 2b = 24

r + 3b = 16

Step-by-step explanation:

Let the red blocks be represented by r

Let blue blocks be represented by b

Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:

3r + 2b = 24

1 red block and 3 blue blocks weigh 16 ounces. This will be:

r + 3b = 16

Therefore, the equation will be:

3r + 2b = 24

r + 3b = 16
