2(4)squared by 2 -3(4)-3

Answer:

15

Step-by-step explanation:

There are 4/4 to make a whole so 2 1/2 cups would be 10 'scoops' and 1 1/4 would be 5 'scoops'. Add 10 + 5 to get a total of 15 scoops.

Hope that helps and have a great day!

Answer

square root of 32

Step-by-step explanation:

in a right triangle we can use Pythagorean theorem to find B

[tex]C^{2} =A^{2}+B^{2} \\\\ 9^{2}=7^{2}+B^{2} \\81=49+B^{2} \\81-49=B^{2} 32=B^{2}\\ B=\sqrt{32}[/tex]we substitute C for 9 and A for 7

Answer:

3 + 7 =10

Step-by-step explanation:

i have three cookies the tree cookies are choclate chip cookies and i have 7 more cookies they are oreos  i add all the cookies and i get 10                                       7 oreos + 3 choclate = 10 cookies

Answer:

the mean is 8

Step-by-step explanation:

To find the mean, add the numbers together and then divide by the number of numbers

( 6+11+7+4+12+15+1)/7

56/7

8

Answer:

9 x 8 = 72

This equation shows that 9 is a factor of 72 because 9 times something is 72 in this equation. Hope it helps!

Answer:

72 / 9 = 8

Step-by-step explanation:

This equation shows that 9 is a factor of 72 because the number at the end comes out as a whole number. If it wasn't a whole number, then 9 would not be a factor of 72. Hope this helps!

Answer:

d. 46

Step-by-step explanation:

46(students) × 40(kg) = 1840(total kg)

Given:

Amount borrowed (P)= $25000

Rate of interest (r)= 6%

Time (t)= 4 years.

To find:

The total interest the company pay in all.

Solution:

We know that,

[tex]A=P(1+r)^t[/tex]

where, A is amount, P is principal, r is rate of interest and t is time period.

[tex]A=25000(1+\dfrac{6}{100})^4[/tex]

[tex]A=25000(1.06)^4[/tex]

[tex]A=25000(1.26247696)[/tex]

[tex]A=31561.924 [/tex]

Now,

[tex]I=A-P[/tex]

[tex]I=31561.924-25000[/tex]

[tex]I=6561.924[/tex]

Therefore, the total interest is $6561.924.

Answer: $6,000

Step-by-step explanation:

The formula to find the circumference of a circle is 2 x pi (π) x radius. The radius is half of the diameter. Therefore, since the diameter is 20, the radius is 10. Pi is equal to approximately 3.14.

3.14 x 10 x 2 is 62.8.

The circumference of the circle is 62.8 m.

Answer: The answer should be j=26/9.

Answer:

y = 3/4x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step 1: Define

(0, -2) y-intercept

(4, 1) random point

Step 2: Find slope m

[tex]m=\frac{1-(-2)}{4-0}[/tex]

[tex]m=\frac{1+2}{4}[/tex]

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

y = 3/4x + b

Step 3: Write linear equation

y = 3/4x - 2

Answer:

13.2 C

Step-by-step explanation:

6am the temp is at -5.7

from 6am to 12pm is 18 hours apart

so if the temp rises at 1.05 every hour you multiply 1.05*18= 18.9

18.9-5.7=13.2

Answer: 6x + 24

Explanation: In this problem, the 6 "distributes" through the parenthses, which means that it multiplies by each of the terms inside.

So we have 6(x) + 6(4) which simplifies to 6x + 24.

Answer: 50 feet

Step-by-step explanation: There are 48 feet in 4 yards, and plus 2 feet would be 50 feet.

Answer:

14 feet

Step-by-step explanation:

3 feet = 1 yard

4 yards = 12 feet

12 feet + 2 feet = 14 feet

Answer:

maybe 13 and 21

Step-by-step explanation:

because there all just adding

Add the two previous numbers for the next number:

1+ 1 = 2

2+ 1 = 3

3+ 2 = 5

5 + 3 = 8

Now add 5 and 8 : 5 + 8 = 13

Now add 8 and 13: 8 + 13 = 21

The two numbers are 13 and 21

Answer: 12x + 2y

Step-by-step explanation:

Answer:

-5/3 = x

x = 5/6 ± 5 sqrt(3)i /(6)

Step-by-step explanation:

0= 27x^3 + 125

Subtract 125 from each side

-125 = 27 x^3

Divide each side by 27

-125/27 = x^3

Take the cube root of each side

(-125/27 ) ^ (1/3) = x^3 ^ (1/3)

-5/3 = x

This is the only real answer

Let me know if you want the complex solutions

0= 27x^3 + 125 = ( 3x) ^3 + 5^3

a^3 + b^3 = (a+b) • (a^2-ab+b^2)

             0   = ( 3x+5) ( 9x^2 - 15x +25)

Using the zero product property

3x+5 =0      9x^2 - 15x +25 =0

3x = -5         9x^2 -15x = -25

x = -5/3       9(x^2 - 5/3x) = -25

Completing the square

                    (x^2 - 5/3x) = -25/9

                     x^2 - 5/3x +25/36 = -25/9 + 25/36

                    ( x-5/6) ^2 = -25/12

                    Take the square root of each side

                    sqrt( x-5/6) ^2 =± sqrt(-25/12)

                       ( x-5/6)  =± 5i/(2 sqrt(3))

                   Add 5/6

                       x = 5/6 ± 5i/(2 sqrt(3))

We cannot leave a sqrt in the denominator so multiply by sqrt(3)/sqrt(3)

                      x = 5/6 ± 5 sqrt(3)i /(2(3))

                     x = 5/6 ± 5 sqrt(3)i /(6)

y= √x

Identify the equation of the function.
