Answer:

35 feets

Step-by-step explanation:

Initial Position = - 25 feets

Final height reached after jumping = 10 feets

The vertical distance traveled by dolphin :

Final height reached - Initial position

(10 feets) - (-25 feets)

10 feets + 25 feets

= 35 feets

Answer and explanation:

Given that 1/2cm= 1 foot

5cm= 2×5=10 feet

Length is twice the width, therefore real length of shape = 10×2=20 feet

Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet

Therefore Deana's Patio= 60 feet in real length

Answer:

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0

2x^{2} (x + 6) - 7 (x + 6) = 0

(x + 6) x (2x - 7) = 0

x + 6 = 0

2x - 7 = 0

x = - 6

x = [tex]\frac{7}{2}[/tex]

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Answer:

O 13

Step-by-step explanation:

g(4) is asking for the function of g when x = 4

g(4) = (4)^2 - 2(4) + 5

g(4) = 16 - 8 + 5

g(4) = 13

I can help with number 7 if you want

1. Equation

y=15x + 10

This is the answer because 10 intercepts on the y axis and it says $15 dollars each.

2. -2 so you do y-y and x-x. In this case its 4-2 and 2-3 which equals 2 and -1 . Which  divided equals -2.

Sorry I can't figure out the rest but I did do these ones.

Given:

15 mL of a solution contains 75 mg of medication.

To find:

How many mg of medication are in 60 mL of solution?

Solution:

We have,

Medication in 15 mL of a solution = 75 mg

Medication in 1 mL of a solution = [tex]\dfrac{75}{15}[/tex] mg

                                                     = [tex]5[/tex] mg

Medication in 60 mL of a solution = [tex]60\times 5[/tex] mg

                                                        = [tex]300[/tex] mg

Therefore, 60 mL of a solution contains 300 mg of medication.

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds

Answer:

Hey! Ok so the answer is 6.

Step-by-step explanation:

If 1 pack has 8 bracelets in each and she has 48 in total then you would have to divide the total to the number of bracelets in each pack so therefore 48 divided by 8 which is 6

6 x (-13) = -78

x - 5 = -78

x = -78 + 5

x = -73

Answer:

Im pretty sure the answer is y=5

Step-by-step explanation:

Answer:

x = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = [tex]\frac{6}{8}[/tex]  <----- to reduce, divide the numerator and denominator by 2

Hence,

x =  [tex]\frac{3}{4}[/tex]

Answer:

h = 14 in

Step-by-step explanation:

Volume = length • width • height

6,720 = 30 • 16 • h                    combine like terms by multiplying 30 and 16

6,720 = 480h                            divide both sides by 480

h = 14 in
