Answer:

50

Step-by-step explanation:

60% of 50 is 30

Step-by-step explanation:

When we have a function in formula form, it is usually a simple matter to evaluate the function. For example, the function \displaystyle f\left(x\right)=5 - 3{x}^{2}f(x)=5−3x

2

can be evaluated by squaring the input value, multiplying by 3, and then subtracting the product from 5.

Answer:

x=-1

Step-by-step explanation:

4(x-3(-2))=6(x-3(-2)) => 4(x+6)=6(x+6) => 4x+24=6x+26 => -2=2x => x=-1

Answer:

20% decrease

Step-by-step explanation:

First, let's find the net decrease: Peter started at 80kg and his weight is now 64kg, which is a 16kg decrease. Next, we need to find what percentage of 80kg 16kg represents. First, let's find what part of 80 is 16:

16/80 = 1/5

To convert this to a percent, we need to find an equivalent fraction to 1/5 with a denominator of 100. To do this, we can multiply the numerator and denominator of 1/5 by 20, giving us 20/100, or 20%.

Answer:

$8.4 million.

Step-by-step explanation:

9% of 7.1 is .639

2011 = 7.1 + .639 = 7.739

2012 = 7.739 + .639 = 8.378

8.378 rounded to the nearest tenth is 8.4

Answer:

  (-3, 3)

Step-by-step explanation:

The midpoint of a line segment is the average of the end point coordinates:

  ((1, 1) +(-7, 5))/2 = (1 -7, 1 +5)/2 = (-6, 6)/2 = (-3, 3) . . . midpoint coordinates

Sides of the prism:

Volume:

Answer:

18ft²

Step-by-step explanation:

V volume pyramid = 1/3× base area × height

V = 1/3 × B × h

24 ft³ = 1/3(12ft²)(6ft)

when V =54 ft³ h= 9ft B =?

V=1/3Bh

B=V3/h

B=(54×3)/9

B=6×3

B=18 ft²

Answer:

slope of line p = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex] ← slope of line p

(a)first term=2

(n)no of term=10

(r)common ratio=8/2=4

sn={a(r^n-1)}÷(r-1)

s1o={2(4^10-1)}÷(4-1)

Answer:

Its c pretty sure

The answer to your question is D

First, you multiply the two decimal numbers, without the x 10 part:

3.84 x 2

7.68

Next, you add the exponents of the 10's:

5 + 6

11

Therefore, it is 7.68 x 10^11

Answer:

136.35

Step-by-step explanation:

Answer:

X = 75

Step-by-step explanation:

here, DY || FS ,

SO, Angle DFS = Angle JDY

( Corresponding angle pair )

Angle JSF = Angle JYD

( Corresponding angle pair )

Hence, triangle JDY ~ JFS ( By AA CRITERIA )

Now, JY / YS = JD / DF

=》42 / 63 = 50 / X

=》X = 50/42 × 63

=》X = 75

Answer:

your answer is 3

Step-by-step explanation:

36 divide by 3 = 12 and 12 divide by 2 = 6 and 6 divide by 2 = 3

Answer:

The answer is below

Step-by-step explanation:

The perimeter of the rectangle is given as:

Perimeter = x + x + y + y + y = 2x + 3y

2x + 3y = 120

2x = 120 - 3y

Dividing through by 2:

x = 60 - 3y/2

The area of the rectangle is given by:

Area (A) = x * y

A = (60 - 3y/2)(y)

A = 60y - 3y² / 2

But the total area = 600 yd², hence

600 = 60y - 3y²/2

multiply through by 2:

1200 = 120y - 3y²

3y² - 120y + 1200 = 0

3y² - 60y - 60y + 1200 = 0

3y(y - 20) - 60(y - 20) = 0

(3y - 60)(y - 20) = 0

3y - 60 = 0, or y - 20 = 0

3y = 60 or y - 20 = 0

y= 20

x = 60 - 3y/2

x = 60 - 3(20)/2

x = 60 - 30

x = 30

Answer:

30 pounds of raspberries and 50 pounds of blueberries

Step-by-step explanation:

Let's use b to represent blueberries and r for raspberries. Each pound of raspberries costs $1, so to find the total cost of raspberries we use 1r, which is just r. For blueberries, we do 3.25b.

r+3.25b=192.5

We also know that we can combine the numbers for 80 total pounds.

r+b=80

We can subtract the two equations we have made to eliminate the r and solve for b.

2.25b=112.5

We divide both sides by 2.25.

b=50

We know that r+b=80, so if b is 50 then r must be 30.

Have a wonderful day! :D

Answer:

50lbs of blueberries = $162.50

30lbs raspberries = $30.00

$192.50 total

Step-by-step explanation:

- 80 pounds totaling at $192.50 -

I found the answer by guessing/estimating between the pound amounts and prices. I eventually got down to 50lbs of blueberries and 30lbs raspberries

3.25 x 40 = $130.00

1 x 40 = $40.00

3.25 x 45 = $146.25

1 x 35 = $35.00

Final Answer:

3.25 x 50 = $162.50

1 x 30 = $30

$162.50 + $30.00 = $192.50

Answer:

14.25

Step-by-step explanation:

im sorry im bad at explaning

Answer:

25！=1*2*3*4*5*6*...23*24*25

26= 2*13

28=2*14or 4*7

36=2*18or 3*12 or 4*9

56=7*8

All products above are inside 25! So they are all factors of 25!

But 58=2*29 and 29 is not inside 25! so it's not a factor of 25!

Step-by-step explanation:

hope it helped

Answer:

n=25

Step-by-step explanation:

Let n be the greatest possible integer Jo could be thinking of. We know n<100 and n=8k-1=7l-3 for some positive integers k and l. From this, we see that 7l=8k+2=2(4k+1), so $7l$ is a multiple of 14. List some multiples of 14, in decreasing order: 112, 98, 84, 70, .... Since n<100, 112 is too large, but 98 works: [tex]$7k=98\Rightarrow n=98-3=95=8(12)-1$[/tex]. Thus,[tex]$n=\boxed{95}$[/tex].

Hope this helped! :)
