PLEASE HELP ME! this is due TONIGHT!! thank you so much

explaining your answer = brainliest/ five stars

the area of the parallelogram is ___ square feet

Answer:

x=3

Step-by-step explanation:

5(2)^x=40

Divide each side by 5

5 /5 *(2)^x=40/5

2^x = 8

Rewriting 8 as 2^3

2^x = 2^3

The bases are the same so the exponents are the same

x=3

Answer:

x = log(40)

Step-by-step explanation:

[tex]5(2)^{x} =40[/tex]

[tex]10^{x} =40[/tex]

[tex]10^{x} =40[/tex]

x = log(40)

Answer:

I think it will be combined and simplified

Answer:

Simplified/combined

Explanation:

In order to simplify an algebraic expression you need to combine all of the like terms which have the same variables and powers.

Answer:

31

Step-by-step explanation:

y=2x^2 - 2x + 7

Let x= -3

y=2(-3)^2 - 2(-3) + 7

 =2 (9) +6 +7

 = 18 +6+7

 = 31

Answer:

350

Step-by-step explanation:

Answer:

200π

Step-by-step explanation:

Surface area of a cone  = πr(r+l)

r is the radius

l is the slant height

Volume of the cone = 1/3πr²h

320π = 1/3πr²h

320 = 1/3r²(15)

320 = 5r²

r² = 320/5

r² = 64

r = 8

l² = 15² + 8²

l² = 225 + 64

l² = 289

l = 17

Get the surface area;

S =  πr(r+l)

S =  π8(8+17)

S = π*8*25

S = 200π

Hence the surface area of the cone is 200π

Answer:

They will win 21 games

Step-by-step explanation:

Here, we want to get the number of possible wins

From the question, we have it that the probability that the team will win is 0.875

Now, out of the 24 games, we simply have to multiply their winning probability by the number of games

We have this as;

0.875 * 24 = 21

Hence, out of the 24, 21 will result in a win

Answer:

27

Step-by-step explanation:

Number of member of staff that drank tee = total number of member of staff - number that drank coffee - number that drank both tea and coffee

100 - 48 - 25 = 27 members of staff

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

2x+3y=15;x+y=6

Rewrite equations:

x+y=6;2x+3y=15

Step: Solvex+y=6for x:

x+y=6

x+y+−y=6+−y(Add -y to both sides)

x=−y+6

Step: Substitute−y+6forxin2x+3y=15:

2x+3y=15

2(−y+6)+3y=15

y+12=15(Simplify both sides of the equation)

y+12+−12=15+−12(Add -12 to both sides)

y=3

Step: Substitute3foryinx=−y+6:

x=−y+6

x=−3+6

x=3(Simplify both sides of the equation)

Answer:

x=3 and y=3

Answer:

x = 3, y = 3

Step-by-step explanation:

Given the 2 equations

2x + 3y = 15 → (1)

x + y = 6 → (2)

Multiplying 2) by - 2 and adding to (1) will eliminate x

- 2x - 2y = - 6 → (3)

Add (1) and (3) term by term to eliminate x

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(3) = 15

2x + 9 = 15 ( subtract 9 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Answer:

10, 100, 1,000, 10,000, 100,000

If you are adding one zero in the end for every number, then 100,000 will be your next number

Answer:

t = -4

Step-by-step explanation:

-6-9t+4=34

-9t=34+6-4

-9t=36

-t=36/9

-t = 4

t = -4

Answer:

t = -4

Step-by-step explanation:

-6-9t+4=34

Combine like terms

-9t -2 = 34

Add 2 to each side

-9t -2+2 = 34+2

-9t = 36

Divide by -9

-9t/-9 = 36/-9

t = -4

Answer:

If a line is parallel with Another...

They will have the same Gradient or equal Gradient (m)

So for two parallel lines

m=m'

So the gradient of the second or other line would be Same

Now

y= -3x + 10

comparing with

y= mx + c

m = -3

So the other line would have the same gradient.

from the options provided in the comment section...

y= -3x + 12

Is your Most probable answer cos it has the same gradient

Answer:

x < -1/2

Step-by-step explanation:

x - 8 > 5x

-8 > 5x -x

-8 > 4x

Divide through by 8

-1/2 > x or x < -1/2.

That is ofcourse if I interpreted the first part correctly.

Answer:

The correct graph is the second. The coefficient -1/8 indicates that the curve opens down.

Answer:

use the slope formula to find the slope of a line given the coordinates of two points on the line and the slope formula is m=( y2- y1)/ (x2 - x1) or the change in the y values over the change in x values.The coordinates of the point represent x1 and y1. The coordinates of the second points are x2, y2.
