Answer:

Quadratic formula

Step-by-step explanation:

You can use the quadratic formula to find solutions for quadratic equations.

Answer:

t=7

Step-by-step explanation:

N=45

find t

45=t^2-t/2

0=t^2-t/2-45

use the quadratic formula

t=6.96~=7

Answer:

Step-by-step explanation:

45 = t2 - t/2

45 = 30(2) - 30/2

45 = 60 - 15

45=45

Answer:

Answer:

21.42ft

Step-by-step explanation:

a²+b²=c² where "c" is the hypotenuse of a right triangle and "a" and "b" are the two other sides

now let's plug in the values

21²+b²=30²

b²= 30² - 21²

b²= 459

b= 21.42

Answer: A

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

For one scientific notation will not work with negative exponents therefore we can eliminate answer choices A and D

Secondly scientific notation usually has a decimal

Answer choice c does not have a decimal point leaving us with answer choice B

Answer:

a

Step-by-step explanation:

both the end points are around the same number

Answer:

$326.94

Step-by-step explanation:

For this equation you are going to do a exponential function, since we are working with percents. To do this you will make the equation

(starting price)x(1-percent)^(t) t=years

which will create the equation

800(0.88)^t

You will then plug in t=7

800(0.88)^7 =

800(0.409) =

326.94 (you will cut it off at the hundredth position because it is working with money)

Answer:

A.4

Step-by-step explanation:

The diameter of the bigger circle is 14

You first subtract 6 from 14 which is 8

8 is the diameter of the smaller circle the radius is 4

your answer is A.

Answer:

y = 5 ; x = 4

Step-by-step explanation:

Given :

5x + 6y = 50 - - - (1)

x - 6y = -26 - - - (2)

From (2)

x = - 26 + 6y

Put - 26 + 6y for x in (1)

5(-26 + 6y) + 6y = 50

-130 + 30y + 6y = 50

-130 + 36y = 50

-130 - 50 = - 36y

-180 = - 36y

y = 180 / 36

y = 5

Put y =5 in x = - 26 + 6y

x = - 26 + 6(5)

x = - 26 + 30

x = 4

y = 5 ; x = 4

4. 22

5. 14

6. 12

7. 45

Step-by-step explanation:

12x4=40+8

20-12=2x4

25-4=3x7

4x9=31+5

16+12=7x4

38-5=3x11

6x7=46-4

Answer:

Step-by-step explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]

Step-by-step explanation:  We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

Answer:

1. Yes the parentheses are necessary. To find a fourth of her regular hours you must find the total amount she works during her regular hours.

2. 6

Answer:

14.96 is the area of the triangle

Answer:

Step-by-step explanation:

use pythagoras

diagonal = [tex]\sqrt{11^{2} + 13^{2} } \\[/tex]

= [tex]\sqrt{290}[/tex]  feet or 17.03 feet

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes

Answer:

-20x+15

Step-by-step explanation:

You use foil method so you distribute it and it becomes -5*4x amd -5*-3 so it would be -20x+15

-5 x 4x=-20x and -5x x -3 = +15

-20x+15 is the answer

Answer:

it would be 128 because 8 divded 2 is 4. 4 is the number of cereal boxes now multiply 4 x32 which would be 128

Answer:

6,666.67cube units

Step-by-step explanation:

Volume of the square based pyramid = BH/3

B is the base area

H is the height of the pyramid

Base area = Length * length

B = 25 * 25

B = 625 square units

Height = 32units

Volume = 625*32/3

Volume = 6,666.67cube units
